Flexible soft seal gate valve features:
Flat-bottom valve seat: Traditional gate valves often deposit in the groove at the bottom of the valve due to external materials such as stones, blocks, cement, paper scraps, debris, etc. after washing the pipe with water. It is easy to cause leakage due to the close closure. The flat bottom design of the lower part of the soft sealing gate valve is the same as that of the water pipe. It is not easy to cause the accumulation of debris and make the fluid smooth and unimpeded.
Integral encapsulation: The valve plate uses high-quality rubber to carry out integral encapsulation and rubber encapsulation. The domestic first-class rubber vulcanization technology enables the vulcanized valve plate to ensure accurate geometric dimensions, and the rubber and ductile iron gate plate are firmly connected, not easy to fall off and have good elastic memory.
Corrosion resistance: The valve body is coated with powder epoxy resin, which can prevent the corrosion and rust of the valve body, and can be used in sewage system.
It is not easy to break: in the past, the traditional cast iron gate valve often caused by external objects hitting, collision or overlap, resulting in fracture and other phenomena.
As the valve is replaced by ductile iron, this situation can be greatly reduced. 53 "O" Ring Seal Ring: Because the valve stem adopts three "0" Ring Seal Ring Seal Design, it can reduce the friction resistance of the switch, greatly reduce the leakage phenomenon, and can replace the sealing ring without stopping water construction.
Help students drink: Because the inner part of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate are completely covered with rubber without rust water or corrosion, so it can be used as raw drink.
Precision Casting Valve Body: Precision casting is used for the valve body. The precise geometric dimension ensures the sealing of the valve body without any finishing. 8 light weight: the valve is made of spheroidal graphite casting, and its weight is reduced by about 20% - 30% compared with the traditional gate valve. Easy installation and maintenance.
The opening and closing part of the elastic seat sealing gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and closed, and can not be adjusted and throttled. Hebei Hengchuang Valve Equipment Co., Ltd. is the leading domestic well-known manufacturer. Its company is the designated management production enterprise of the Ministry of Machinery Industry, the Ministry of Chemical Industry and China Chemical Equipment Corporation. Its products have certain price advantages and technical advantages in the industry.
