Water pressure regulators are devices whose main purpose is to maintain the necessary pressure or lower it. It should be noted that often these devices are also called step-down valves or gearboxes. Thanks to them, the probability of breakdown of system elements
due to pressure surges is reduced almost to zero
. In this regard, such valves are widely used not only in industrial, but also in domestic systems. Among other things, the water pressure regulator for the pump significantly reduces the noise level during its operation.
Principle of operation
The principle of the device’s operation is based on the equalization system. More specifically, the direction of the stem force is the opposite of the elastic force that characterizes the tuned spring. As soon as the water level drops as a result of water intake, the valve opens under the action of the spring's elasticity (in other words, its strength). Until the moment when the balancing of the forces of the spring and the rod occurs, the output pressure indicator will rise. As for the incoming, it does not have any effect on the opening or closing of the valve. A high-quality domestic version of this device, which is recommended by many experts, is the RD-15 water pressure regulator. All materials used in its manufacture have been certified and authorized by the Russian Ministry of Health.
Industrial use
As already noted above, in industrial plants and systems, the device is designed to reduce excess pressure and minimize the likelihood of water hammer.
In addition, water pressure regulators contribute to an increase in the terms of operation of units and machines. The fact is that a certain
pressure of a gas or liquid in many technological processes must be constant. To ensure this without the use of gears is almost impossible. If you look from an economic point of view, water pressure regulators are simply irreplaceable, because in most cases the process equipment itself and its repair are estimated at very large sums of money.
Domestic use
Reducers are widely used to get rid of high pressure in private homes and apartments. The device avoids water hammer, and also protects many plumbing fixtures from damage. These include showers, washing machines and dishwashers, faucets and others. If there are no water pressure regulators at home, this often leads to increased wear and the gradual destruction of their seals and gaskets, resulting in water leakage.
conclusions
In conclusion, it should be noted that the use of the gearbox can be safely called economically feasible. In this regard, the vast majority of heating and water supply systems are designed and constructed with the mandatory use of water pressure regulators.
