Reducer for stable pressure in the water Bashny.Net

For stable pressure in the water and it is likely always to use a useful unit like a pressure reducer. The device is responsible for automatic control of water pressure and most importantly, that it does not require additional Electromechanical and electric actuators.

The gearbox is a reliable protection of the sanitary equipment from high pressure surges of fluid in the pipeline. The unit of regulation of the water pressure is sealed from the metal. It is equipped with output and input ports with internal thread. Can be equipped with a screw to regulate pressure and a nozzle with a small diameter for connection to a pressure gauge.

The full composition of the mechanism

The pressure reducer consists of the following components:

• A housing with a lid;
• Spring;
• Mesh filter;
• Nut and screw to adjust pressure;
• Pressure gauge;
• Aperture;
• The piston and the plate;
• The Central stand;
• The valve seal;
• The presser bolt;
• Small and large o-ring.

Where mounted reducer

Recently, the pressure reducer can often be seen in front of a washing machine, boiler, gas stove and other household units that "feed" water. It happens that before installing the plumbing in the apartment or house, was not planned in advance fixing a "controller" of pressure on the entire indoor environment. This should be considered at the time of installation of the unit. Before the reducer, it is recommended to install a water purification filter. Similar way to protect the device quite useful, despite the fact that in some of the latest models of gearboxes already installed custom filter.





The working principle of reducer

The principle of the water pressure regulator is based on the alignment of the spring forces and efforts of the diaphragm. When the valve opens, the pipe decreases output pressure of the reducer, and this in turn reduces the pressure on the diaphragm. In this case, the force of the spring more and with its stabilization it opens the valve as long as the outlet pressure is equal to the specified value. At the same time, the output pressure of the regulator and its differences absolutely have no effect on closing or opening of the valve.

The pressure reducer installed on the inlet pipe, which reduces the pressure to the required performance and aligns it in all the water system of homes. If, at the time of installation of the pipeline it has not attached the controller of the liquid, it is possible to supply the reducer to the washer, dishwasher or water heater. It is very important to perform this event, if the piping system contains a pump, which creates water hammer (rapid pressure drop in the pipe) when you turn on and off.

Installation of pressure reducer

Typically, the pressure reducer pressure gauge set up on the section connecting the water supply to the riser or main pipeline. Best water pressure regulator to be mounted on a horizontal clearance plane, behind the counter.

In addition to this, it is necessary to put the filtering system primary filter before installing reducer. But, if the filter is already available at the input of the pipeline, it is possible to do without re-installation. To control water pressure and immediately followed by a need to attach a check valve. Setting and monitoring the pressure in the water needs to be adjusted if the water flow is zero.





It is necessary to leave a straight cut on the pipe after reducer (not less than 5 working diameters). The pressure adjustment device can be set independently, but only if you have experience in plumbing activities. But, to deliver quality work and guarantee correct installation, it is advisable to seek help from a professional plumber.published
