Product Description

As a manufacturer, we can carry out special design of the sealing surface according to customer requirements, and theoretically the design structure of the hard seal can achieve zero flow without leakage.
2, if there is a frequent small flow of water in the branches of the pressure reducing valve (such as a variety of domestic water), then even if there is a slight drip leakage, the increased pressure after the valve can be discharged in time. The hard sealing structure pressure reducing valve with higher degree and stronger anti-cavitation ability is better than the pressure reducing valve with soft sealing structure.
At the same time, the ZJY46H piston pressure reducing valve with soft seal is also effective. The sealing surface of the soft seal material can ensure that the high pressure water in front of the valve will not leak into the pipeline behind the valve, and the pipeline behind the valve still maintains low pressure. With the development of economy, low noise, safe, stable and reliable self-flow water supply must be the mainstream in the future. We have confidence and technology more ability to control the operating noise of ZJY46H combined pressure reducing valve in various complex conditions at 80-87dB.
The utility discloses a low noise pressure reducing valve, which belongs to the technical field of valves, including a valve body, interconnected and arranged at both ends of the valve body inlet and outlet, the valve seat hole between the intake and outlet and the valve cover installed on the top of the valve body, the valve body and the valve cover cooperate and form an inner cavity, the inner cavity is equipped with a movable valve stem, the lower end of the valve stem is provided with the valve seat The hole constitutes the sealing of the opening and closing valve flap, the side wall of the valve body is provided with a number of soundproof cavity, soundproof cavity is provided with acoustic cotton; The valve body is provided with upward through the piston hole and matching activities installed in the piston hole, the upper chamber is provided with a pressure regulator, the upper end of the valve stem through the piston, the middle of the valve stem and the piston are fixed between each other, the upper chamber is provided with a set of spring outside the valve stem, the upper end of the spring and the regulator is fixed, the lower end of the spring is fixed with the piston. It can reduce the noise caused by the water flowing from the pressure reducing valve.

ZJY46H higher degree of cavitation resistance stronger high pressure reduction than piston combined pressure reducing valve
The utility model relates to a self-regulating pressure reducing valve with water pressure, which keeps the pressure and flow at the outlet stable when the inlet pressure and flow change. Its complete self-control, simple debugging, operation can be when the pipeline flow rate is 0, the pressure reducing valve into the full closed state, the pressure after the valve to maintain low pressure (can reduce static pressure) as shown in the figure: when P1 changes, the pressure reducing valve outlet first performance P2±△P2 through the feedback system outlet pipe to the control valve, so that Pt=Pk±△P2; Thus L changes accordingly, resulting in the change of ±△Pe, resulting in the corresponding change of Pk through the pressure conduit, Pt and Pk reach a new balance, the main valve flow area H changes accordingly, therefore, P1 changes, and the flow through H remains unchanged. P2 is always the low pressure value of the original setting. When the flow rate changes, the self-regulation of the pressure reducing valve works as above.
ZJY46H low noise combined pressure reducing valve technical requirements
(1) The design, manufacture and test of all parts and spare parts of the pressure reducing valve should meet the requirements of the corresponding equipment, materials and components.
(2) The reducing valve of the power station shall be a piston type reducing valve and adopt a decompression mode.

(4) Adjustable pressure reducing valve in a stable flow state, the outlet pressure is constant, when the inlet pressure changes, the outlet flow deviation value shall not exceed 10%. When the inlet pressure is constant and the outlet flow rate changes from the maximum flow rate of 20% under the working condition to the maximum flow rate, the negative deviation value of the outlet pressure shall not exceed 10%. The pressure reducing valve should be equipped with a throttling device, and in the case of relatively large pressure loss, there is a wide flow range.
The pressure reducing valve is in a stable flow state, the outlet flow is constant, and the outlet pressure deviation value shall not exceed 5% when the inlet pressure changes.
(5) The control water pipe of the pressure reducing valve should be installed with a detachable filter to prevent silting.
(6) The pressure reducing valve is equipped with stainless steel valve position indicator to indicate the opening position of the valve.
(7) The pressure reducing valve has no abnormal blocking, slip, vibration and noise in the running state, and has high adjustment sensitivity and accuracy, and small head loss.
(8) The life of the pressure reducing valve should be above.
(9) The noise of the pressure reducing valve in the range of 1m should be less than 90dB.
(10) The body material of the pressure relief valve is alloy cast steel.
