What is a hydraulic pressure reducing valve?

hydraulic pressure reducing Industrial Valves is a kind of USES the energy of water to regulate and control line pressure intelligent pressure reducing valve.

hydraulic pressure reducing valve used in the drinking water, fire water, and other industrial water supply system, by adjusting the pressure pilot valve, can adjust the outlet pressure of the main valve.

outlet pressure does not change because of the change of inlet pressure, inlet flow, safe and reliable to keep outlet pressure on the set value, and can according to need to adjust the Settings to achieve the relief.

hydraulic pressure reducing valve, decompression precision, stable performance, safe and reliable, easy installation and adjustment, long service life.

ZJY46H piston hydraulic pressure reducing valve is a new 7 series of patented technology products, stable and reliable for the technical water supply system for hydropower station of cooling water.

hydraulic pressure reducing valve model is introduced:

ZJY46H piston type hydraulic 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.

the 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 hydraulic pressure reducing valve structure shows schematic

a part, the main valve

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, part of the feedback system

by the 3-way switch valve, control valve, drain valve, jet pump, pressure pipe, outlet pressure locking valve ( 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 Industrial Valves. Standby system available in the pressure reducing valve under the condition of disassembly repair.

three, regulating mechanism

ZJY46H piston hydraulic 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.

hydraulic pressure reducing valve working principle:

a, ZJY46H piston hydraulic pressure reducing valve working principle:

ZJY46H piston working principle of hydraulic pressure reducing valve is controlled by the feedback on the system control valves, jet pump chamber pressure regulation, make the pressure regulating cavity and the main spring pressure balance.

due to the spring pressure is not affected by the inlet pressure P1, so when P1 inlet pressure and flow change, always can quickly adjust the spring pressure and the pressure regulating cavity pressure balance, keep P2 outlet pressure and flow stability.

2, ZJY46H piston hydraulic pressure reducing valve outlet pressure locking system working principle:

outlet pressure locking device is composed of safety lock nut, tie rod and the piston rod, effectively ensure the safety of outlet pressure P2 value.

by easily set the safety lock nut, can lock the outlet pressure of the relief valve cap. Even ZJY46H piston hydraulic pressure reducing valve feedback system suffered from accidental damage, in the main piston at the bottom of the pressure regulating cavity loss of pressure, the outlet pressure P2 value can be very rigid protection, reliable locking cap on the discharge pressure.
