Double self-sealing anti-counterfeit seal valve Features:
F43X-10 double-sealed self-cleaning anti-reverse valve is the main application of dry clearance, reservoir overflow pipe. Usually there is a solid seal valve seal to stop the sewage pipe into the clean water, due to heavy rain sewer blockage caused by rain Sewage pipe water level can be increased to prevent water intrusion pool, is a good water supply health protection device.
Double-sealed self-cleaning anti-counterfeit valve main performance:
Double self-sealing anti-reverse water seal valve structure is simple, smooth and unobstructed overflow, with double water seal. Barrier odor and sewage intrusion, reliable performance, good effect, and when the sewage intrusion debris does not affect the sealing performance.
Double self-sealing anti-counterfeit valve working principle:
F43x10T anti-reverse water-proof valve is mainly composed of a body with a water trap and a float cover, etc. The cover with a float covers the sealed valve seat of the valve body and divides the valve chamber into two parts, inner and outer Part of the water, the outer cavity through the drain pipe, when the cavity is filled with water, the target is located in the visceral float for the month, reducing the lid pressure, easy to open the flow. After the overflow stops, the cover plate can reset itself, and the tight valve seat can strictly cut off the odor and sewage. If the pool inlet float valve is closed well. Years without overflow, the valve cavity is dry, floating ball can increase the weight of the cover. Better cover strict seat, the head can be strict sister stench and prevent rain, sewage intrusion Clean water tank. If the sewage into the body cavity, the debris can only be attached to the outer surface of the cover, does not affect the cover seal Yan seat. Therefore, the anti-counterfeit Mizuki work reliable. Good effect, not easy to fail. And when there is debris precipitation, T times overflow can automatically out of the valve body.
