The water pressure regulator uses the opening degree of the opening and closing parts of the control valve to regulate the flow of the medium, reducing the pressure of the medium, while regulating the opening degree of the opening and closing parts with the help of the post-valve pressure to keep the post-valve pressure within a certain range - the type of pressure reducing valve and the accuracy of pressure regulation are selected according to the requirements of use, and then its diameter is selected according to the maximum output flow required. Buy the lowest priced water pressure regulator at ATO.com and choose from a wide range of adjusting water pressure regulator sizes, 1", 3/4", 1/2" to 2".
The water pressure regulator reduces the water pressure by the local resistance of the flow channel in the valve to the water flow. The principle of constant ratio decompression is controlled by the water pressure ratio of the floating piston in the valve body, and the decompression ratio at the inlet and outlet is inversely proportional to the area ratio of the piston at the inlet and outlet.
The pilot-operated pressure reducing valve changes the flow rate and kinetic energy of the fluid in the pipeline system by changing the throttling area, and after different degrees of pressure loss, the purpose of reducing the pressure inside the pipeline is achieved. Through careful control and adjustment, the internal pressure of the valve can be reduced. The fluctuation of the valve and the spring force reach a balance, and finally the pressure after the valve in the pipeline is kept constant within a certain error range.
Pilot operated pressure reducing valves use hydraulic operating principles to achieve control. As a component for adjusting and throttling local pressure changes, the pilot-operated pressure reducing valve reduces the inlet pressure to a set outlet pressure range by adjusting the inlet pressure, and then automatically keeps the outlet pressure stable by virtue of the energy of the medium itself.
Turn off the water end of the pressure reducing valve after the valve, then open the black cover on the adjusting spring, there is a word starter adjustment, from top to bottom, clockwise rotation of the outlet pressure increases, counterclockwise rotation of the outlet pressure decreases, while adjusting to observe the pressure gauge reading on the valve body or after the valve, stop adjusting after reaching the required pressure and reset the black cover.
Self-operated water pressure regulating valve itself functions as a pressure regulator, although in some conditions the flow rate can be changed by changing the pressure parameters, but this is the result of the impact of the equipment process, not the function of the self-operated water pressure regulating valve. Self-operated water pressure regulating valve itself does not have the function of flow regulation.
Self-operated water pressure regulating valve is divided into two types of adjustment before and after the valve, respectively, can only adjust the pressure before or after the valve, that is, before the valve type regardless of how the pressure fluctuations after the valve, only adjust the pressure before the valve to maintain stability; the same after the valve type only after the valve regardless of the valve before.
After the use of the valve type self-operated water pressure regulating valve to adjust the pressure after the valve, there is a continuous rise in the valve reed reasons:
