Performance and features

F43X-1.0-type double sealing self-purification anti-reversed water sealing valve is the latest product that researched open valve according to abroad technology. It is mainly used in the clean, reservoir overflow pipe, usually because it has water sealing internal to prevent sewer odor entering into the clean water tank, rain or sewer blockage caused sewage pipes to stop sewage flowing into clean water tank, anti-reversed water sealing valve is a good water supply and sanitation protection device, with simple structure, smooth and unimpeded overflow, a double sealing effect, reliable blocking and exhaust and sewage backflow, good effect, and the debris carried by water intrusion will not affect the sealing performance.

working principle

F43X-1.0T double sealing self-purification anti-reversed water sealing valve is mainly composed by trap bending valve and the floating ball cover components, etc. with floating ball cover is covered on the body sealing seat, dividing the valve cavity into inside and outside parts, internal wall of clean water while external wall of drainage pipes, when the interior is full of water, as a result of the floating ball, the cover pressure reduces, easy to open the same stream. Overflow stopped, the cover can be self-reset, cover the seat tightly, which can strictly block the exhaust and sewage flow backward. If the pool port float valve shut down well, a few years it will not overflow, no water in valve cavity, floating ball can enlarge the valve weight, better to cover the seat, and meanwhile can strictly separated odor and prevent rain water intrusion clean water tank. If the sewage enters into the body external cavity, the debris only can adhere to the cover external surface, and will not cover sealing seat tightly. So the anti-reversed water sealing valve has reliable working, good effects, hard to fail. When there is debris and sediment, the next overflow will automatically rush them out of the body.
