Product description:
The HS41X-A anti-fouling block valve with filter consists of two separated check valves and a hydraulic transmission to Drain valve is formed, and filter screen is housed in the valve body of the first check valve. Local head loss due to check valve Loss, the pressure in the middle cavity is always lower than the pressure of the water inlet. This differential pressure forces the drain valve to close
In the closed state, the pipeline supplies water normally. When the pressure is abnormal, (that is, the pressure at the outlet end is higher than that of the central cavity), that is The two check valves cannot be reversely sealed, and the safety drain valve can also be automatically opened to drain the backflow water.
And form an air partition to ensure the sanitation and safety of upstream water supply. The sub-product structure is reasonable, the use Convenient products, strong sealing performance, durable and beautiful appearance. Widely used in electric power, metallurgy Gold, petroleum, chemical industry, gas, urban construction, papermaking, textiles, medicine, food, ships, water supply and drainage, energy, drilling and other sectors.
