ZJY46H piston type pressure reducing valve product introduction:

ZJY46H piston type pressure reducing valve is designed for complex conditions the pressure-relief devices of the running water supply system design, through the throttle cones to adjust pressure and flow rate, pressure to reduce the flow area to achieve. When the inlet pressure or flow changes, pressure reducing valve automatic adjustment by the energy of the medium itself, to maintain the outlet pressure of the original set low voltage value.

ZJY46H piston type pressure reducing valve main function for the following four points:

1, decompression, voltage regulator, voltage regulator;

2, locking outlet pressure;

3 recoil blowdown, feedback system;

4, as spare double feedback system.

ZJY46H piston type pressure reducing valve structure diagram

a, the main valve parts

by the valve body, valve cover, the main valve control system ( The main valve adjustment plate bar or the reducer to adjust the handwheel, adjusting screw) , outlet pressure locking system ( The locking lever, safety lock nut, flat bearing, lock nut) .

2 and feedback system part

by the 3-way switch valve, control valve, drain valve, jet pump, pressure pipe, outlet pressure locking Industrial Valves ( China ball valve) And exhaust of bolt.

this product feedback control system is given priority to, prepare two sets. Through the 3-way switch valve switch, to ensure the continuous operation of the pressure reducing valve. Standby system available in the pressure reducing Industrial Valves under the condition of disassembly repair. Three, regulating mechanism

ZJY46H piston type pressure reducing valve regulating mechanism of points is given priority to valve control system and feedback control system of two parts. Adjust the position for the main valve adjusting screw; Adjust the position of control valve adjusting cap feedback control system.

adjusting mechanism is an important component of the pressure reducing valve. When through adjusting mechanism after setting the outlet pressure, running pressure reducing valve on the condition of inlet pressure and flow change, can automatically adjust the pressure reducing valve flow area, maintain the stability of outlet pressure.
