The role of the hydropower station, fire control system, pressure reducing valve: hydropower station, fire control system, usually is to keep the high pressure normally closed system, hydropower station, fire control system pressure reducing valve requires a good sealing and stability.

hydropower station, fire control system working principle of the pressure reducing valve, was closed after the pressure reducing valve valve valve, pressure reducing valve to maintain a good sealing under high pressure working conditions; Open the valve after pressure reducing Industrial Valves, pressure reducing valve can be rapid response, setting pressure of water.

at the same time many hydropower station fire fighting system with water is water and hydropower station setting together, this design puts forward higher requirements on the sensitivity of pressure reducing valve. In the small flow rate under the condition of pressure reducing valve need to often open, and ensure the stability of the valve after pressure.

ZJY46H piston type pressure reducing valve applied in hydropower station on the fire protection system is very much, it has eight to 15 years of steady working condition of ability, can self adjustment without external power supply outlet pressure, responsive. And outlet pressure locking system, recoil drainage system, double feedback system, such as multiple protection device. In the three gorges hydropower station, xiangjiaba hydropower station, the natural arch hydropower station at home and abroad, such as hundreds of hydropower station has a good application performance, pressure reducing valve is a very good hydropower station, fire fighting system.

ZJY46H piston valve is the patent product development. Widely used in pipes, pressure vessels of overvoltage protection. In the pipeline and pressure vessel pressure overload, automatic overload release part of the dielectric fluid, to keep the pressure within the scope of the TVC. ZJA46H piston type pressure relief valve is proved by many years of plant operation, the product performance and reliable, high durability, by users praise.

ZJY46H piston type pressure reducing valve is a new 7 series of products, developed by XFY46H combined pressure reducing valve in the 90 s.

compared with similar products, ZJY46H piston type pressure reducing valve with high pressure, high flow rate, inlet pressure strong adaptability, low noise, long life and other advantages of obtaining customer high praise. Widely used in hydropower station and pumping station at home and abroad, and mine deep well. For example, lijiaxia, orb temple, natural arch, xiaolangdi, goupitan, xiangjiaba, etc.
