Installation of plumbing equipment in a home, in an enterprise or in municipal institution usually carried out in accordance with all the rules of maintenance and operation. Most consumers purchase plumbing fixtures from reliable manufacturers, but some factors can damage any fixture. For example, water pressure drops in the water supply system often cause breakdown of devices. To solve this problem, it is worth installing a water pressure regulator.

What is a water pressure regulator, what is the principle of its operation

A regulator, or water pressure reducer (WFR), is a special regulating device for plumbing that maintains the water pressure in the normal range. Sudden changes in pressure can not only ruin expensive equipment, but also damage repairs in an apartment or house, which leads to new costs. The reducer mechanism is able to reduce the force of the fluid supply to the normal level and prevent water hammer.

There are two types of WFD design, differing in the direction of regulation:

from oneself - works in a pipeline installed on a plumbing branch;
to himself - works on the highway towards the plumbing fixtures.

The principle of operation of both types is to change the valve section. At a stable pressure not exceeding the norm, the service valve is kept open. Minor surges provoke automatic valve closure, which reduces the head and reduces the risk of breakage of the drainage pipes.

brass or steel body (1) with cover (2) and plug (3);
adjusting bolt for setting the mechanism (4);
nut for fixing the bolt (5);
piston rod (6, 13) with cylinder (8);
mechanical springs (7);
diaphragm (9) with a distribution ring (10) or a piston in a mechanical model;
a service valve consisting of a screw (11) and a gasket (12);
seal (14) and damper chamber for plug (15).

Also, gearboxes, depending on the manufacturer and purpose, are completed with additional elements - air valves, filter, pressure gauge, ball valve.

Hot and cold water regulators are static and dynamic. The former maintain the adjusted pressure level on a constant basis, the latter are designed for continuous water supply and flow. Reducers are used in domestic and industrial municipal water supply, on pumping stations and in fire services, as well as at water stations and reclamation stations.

What are the types of regulators in the water supply system

Modern stores offer to buy water pressure reducers of any kind and purpose. There are several classifications of WFD types.

Regulators differing in internal structure and principle of operation:

piston - mechanical devices in demand due to their low price and ease of use;
diaphragm - more powerful and expensive devices powered by springs and a diaphragm.

Types of regulators by control method:

electronic - equipped with an electric sensor that scans the pressure to activate the pump;
automatic - equipped with a block with springs and nuts, susceptible to pressure drops.

Piston reducer works from springs, a piston and a valve, which, depending on the pressure, control the operation of the spool. The advantages of this design are affordable cost, ease of installation and a simple, reliable mechanism. Of the minuses, it is worth noting the high sensitivity to dirt and friction of parts.

Diaphragm reducer characterized by increased throughput, excellent performance and long service life without breakdowns. The device is powered by a spring-loaded diaphragm, which is located in a special sealed compartment. Such devices have a high price, but it is justified by the powerful technical characteristics.

There are also flow regulators, which are rarely used, but have good properties. They lack a movable mechanism - the internal structure consists of numerous ducts and compartments. Water entering such a labyrinth slows down the speed of movement, which reduces its pressure and protects the plumbing from water hammer.

Technical characteristics of popular RFE models

Installation of the RDV regulator

It is recommended to entrust the installation of the water pressure reducer to specialists and experienced craftsmen. This is the only way to get a guarantee of reliable long-term operation of the device without unscheduled repairs. If there's practical experience in the installation of plumbing or measuring equipment on pipes, you can install the WFD with your own hands.

The procedure for installing the gearbox in the apartment:

Disconnect and shut off water throughout the riser. If necessary, notify your neighbors about the temporary shutdown.
Place an inlet valve on the pipe between the ball stop valve and the meter.
Attach a coarse particle filtration system behind the counter.
Place the regulator on a horizontal pipe.
Seal all joints of the parts using a sealant.
Adjust the position of the pressure gauge so that the dial is clearly visible.
Connect the installed WFD to ball valve, check the consistency of the device.

Installation of the RFE in a private country house is slightly different from the apartment building. In order to prevent water hammer and breakdown of plumbing equipment in the house, you should put the regulator right behind the meter, and then install a check valve, filter and tap.

To choose a reliable device for adjusting the water pressure, you need to know some parameters that should be considered:

Bandwidth. For domestic use, 0.1-0.15 m³ / hour is recommended, for commercial use - 0.2-0.3 m³ / hour, for industrial use - over 0.3 m³ / hour.
Allowable pressure loss. With a low water consumption, it is considered the norm to be 1-2.5 Bar, with an average - 2-5 Bar, with an increased one - 4-7 Bar.
Diameter of the flow area. Measured in inches and depends on the destination. For residential buildings, the diameter should be ½ "to ¼", for industrial buildings, between ¾ and 2 ".
Connection method. There is a flange and threaded (coupling) connection of parts that differ in the type of fastening and cost.

If you have a choice - to install a water pressure regulator or not, the answer is unambiguous - to install. The device fully justifies its cost, and consumers note a lot of advantages of the WFD installation:

reliable and durable plumbing resistance to hydraulic loads and pressure drops;
long-term preservation of plumbing equipment in a house, apartment or at an enterprise;
financial savings due to reduced water use;
lack of noise in the pipeline and during the operation of the reducer;
stable outlet pressure regardless of the inlet level.

Regulator water pressure - the little defender of plumbing fixtures!

Water pressure regulators are designed to stabilize and lower the pressure in the water supply system. The pressure reducer is important element in the system, it is a protective device, for example, we will conditionally compare it with a voltage stabilizer of a 220 volt network, the stabilizer protects electrical appliances from sudden power surges in the network, and a water pressure reducer protects plumbing fixtures and household appliances (washing machines, drinking water purification filters, water heaters, etc.).

Requirements for installing water pressure reducers:
Installing a pressure reducer is quite simple, the main thing is to adhere to the following rules.

The reducer must be installed after the mechanical water filter.
Installation is carried out strictly according to the arrow of the water flow indicator.
As a rule, the reducer has a hole for installing a pressure gauge with a pressure scale; pressure gauges are available with rear and vertical connections. The pressure gauge is installed with the scale up.

Water pressure setting :

The pressure is adjusted by turning the screw, which presses or loosens the spring, which in turn opens or closes the service valve.
Pressure reducers generally allow the outlet pressure to be set from 0.5 to 7 bar. Recommended pressure for apartments is 2 - 3 atmospheres.
To decrease the water pressure, the screw is turned counterclockwise, by turning the screw in the opposite direction, the pressure will increase.

Diaphragm and piston water pressure regulators - what are the differences?

Mdiaphragm regulator pressure due to the presence of a compensation chamber and a shut-off membrane, allows you to obtain a stabilized outlet water pressure at the outlet.

The main advantages of such gearboxes are:

Diaphragm reducers water pressure have no rubbing parts, for this reason they are not so demanding on water quality and the reliability of such gearboxes is significantly higher than that of piston gearboxes with spring blocks.
As a rule, diaphragm regulators have an extended adjustment range - from 0.5 to 7 bar.
Better smooth out pressure drops water inlet.
Work with a large pressure range.
Operation with lower water consumption... But the price of such gearboxes is much higher than that of piston gearboxes.

Piston water pressure reducer in its design contains a piston, which is biased by a spring. Depending on the outlet water pressure, the piston presses the passage that releases the water to the outlet.

Feature of piston water pressure reducers:

The presence of moving parts inside the case.
Higher filtration requirement for inlet water.
The maximum water flow rate is limited to 2 m / s (to exclude increased wear of the piston mechanism).
With a large flow of water, a significant decrease in pressure occurs.

NEW New arrival to our range of water pressure reducers - diaphragm pressure reducers from the manufacturer OFFICINE RIGAMONTI(Italy)

Distinctive features of OR series 0028 diaphragm regulators:

Company OFFICINE RIGAMONTI, abbreviated (OR) previously produced diaphragm water pressure reducers for company VALTEC, model VT.085.N, which has proven itself from the good side. Plumbers and installers are happy to use these products to this day, but pressure reducers VALTEC do not have detachable connections, which in turn greatly simplify installation and subsequent Maintenance appliances.

In water pressure regulators, plug-in function implemented... The basic set includes American women 1 / 2x3 / 4 ", this functionality was previously available only in premium gearboxes e.g. pressure reducer FAR HP-HP series FA 2810 or pressure reducing valve Honeywell D06F B... But the cost of such models is significantly higher than that of gearboxes from the manufacturer. OFFICINE RIGAMONTI, while the admissible maximum temperature at FAR and Honeywell -70 ° C, what 10 ° C less than OR gearboxes, where the permissible temperature is 80 ° C , the safety margin of OR membranes adds reliability to the water supply system.

The most different types equipment: from conventional mixers and plumbing fixtures to complex and expensive household appliances... As a rule, the performance of all this equipment depends on the stability of the water pressure in the pipeline. However, for our engineering systems pressure drops are common, forcing the search for additional solutions to protect plumbing equipment and household appliances. For this purpose, special devices are used - pressure regulators, which our company sells in Moscow at competitive prices.

Application of pressure regulators

A household pressure regulator, or reducer, is a device that allows you to maintain a constant water pressure in the pipeline. These devices are widely used not only in everyday life, but also in the commercial sphere, as well as in small production facilities.

The main purposes of using gearboxes:

Protection engineering networks from water hammer.
Protection of plumbing fixtures and household appliances from failure due to pressure drops.
Reduced water consumption.
Maintaining a stable outlet water pressure.
Reducing water flow noise.

Types of pressure regulators

The main operating element of the gearbox is a regulating device in the form of a valve. As the water pressure increases, it decreases its flow area, which leads to a decrease in the outlet water pressure. When the inlet pressure drops, the valve opens, thereby increasing the outlet pressure.

Today, several types of pressure regulators can be used, the choice of which depends on various parameters. Including, depending on the method of maintaining pressure, water regulators for statics and dynamics are used. Static regulators are used for installation in water supply systems in apartment buildings and private houses, which are characterized by an uneven water intake. Dynamics controllers are used in cases where the flow of water in the pipeline is continuous. In the domestic sphere, such devices can be used, for example, to protect the equipment of heating systems.

Depending on the type of connection to the pipeline, a distinction is made between gearboxes with threaded (coupling) or flange connection... The most common in everyday life are clutch pressure regulators.

Diaphragm and piston gearboxes are distinguished by the type of control device. Diaphragm regulators are characterized by high reliability, resistance to corrosion and pollution. However, their weak point is the membrane, the condition of which must be regularly monitored. Piston pressure regulators are not subject to wear and can have a virtually unlimited life. Their disadvantage is the rather high requirements for care. In addition, the presence of abrasive contaminants such as sand particles in the water can damage the gearbox.
