Z15X silk mouth soft sealing gate valve utilizes the overall encapsulation of the gate to produce deformation compensation to achieve a good sealing effect, which overcomes the phenomenon of poor sealing, water leakage and rust of general gate valves. Material deposition, small flow resistance coefficient, smooth channel. The inside and outside of the valve body is coated with non-toxic epoxy resin to prevent corrosion and rust. It can be used not only for domestic water, but also for sewage treatment system. Widely used in tap water, sewage, construction, petrochemical, food, medicine, textile, electric power, ships, metallurgical energy systems and other fluid pipelines as regulating and throttling devices. Structural features of Z15X soft-sealed gate valve 1. Flat-bottomed valve seat: Traditional gate valves often accumulate in the groove at the bottom of the valve due to foreign objects such as stones, wood blocks, cement, paper scraps, sundries, etc. after the pipe is washed with water. Inside, it is easy to cause the phenomenon of water leakage that cannot be closed tightly. The bottom of the soft-sealed gate valve adopts the same flat-bottom design as the water pipe, which is not easy to cause debris to accumulate, so that the fluid is unobstructed. 2. Overall rubber coating: The valve is made of high-quality rubber as a whole and covered with rubber. The domestic first-class rubber vulcanization technology enables the vulcanized valve to ensure accurate geometric dimensions, and the rubber and ductile iron valve are connected firmly, not easy to fall off and elastic Good memory. 3. Corrosion resistance: The valve body is coated with powder epoxy resin, which can prevent the valve body from corroding and rusting. And can be used in sewage system. It is not easy to break. Traditional cast iron gate valves often break due to foreign objects hitting, colliding or overlapping. Due to the use of ductile iron for the body, this situation can be greatly reduced. 4. Three 'O' type: Because the valve stem adopts the design of three 'O' type ring seals. It can reduce the frictional resistance when switching, greatly reduce the phenomenon of water leakage, and can replace the sealing ring without stopping the water construction. 5. It is helpful for raw drinking: Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate valve are completely covered with rubber, so that there will be no rust or corrosion, and it can be used for raw drinking. 6. Precision casting valve body: The valve body adopts precision casting, and the precise geometric dimensions make the valve body's northern part without any finishing to ensure the sealing performance of the valve. 7. Light weight: The body is made of ductile ink casting, and the weight is about 20% to 30% lighter than that of the traditional gate valve, which is convenient for maintenance.
In an age when valve application is increasingly important, the researchers believe manufacturers should pay close attention to their results.
