Product description:
The soft sealing gate valve is the compensation effect of the overall elastic deformation of the gate plate to achieve a good sealing effect, and overcomes the poor sealing, water leakage and rust of the traditional gate valve. The driving torque is small, and the operation is simple and fast. It is widely used to cut off the flow of medium in fluid pipelines such as tap water, sewage, construction, petroleum, chemical industry, metallurgy, and electric power.
Technical Parameters:
Nominal diameter: DN50 ~ DN1200mm
Nominal pressure: PN1.0 ~ 1.6MPa
Use medium: oil, water, sewage, etc.
Operating temperature: ≤120℃
Drive mode: manual, electric drive
Design standard: design and manufacturing standard CJ/T216 "soft sealing gate valve for water supply and drainage", flange connection standard GB/T17241.6 "monolithic cast iron flange", structural length standard GB/T12221 "metal valve structural length", test and Inspection standard GB/T13927 "Industrial Valve Pressure Test"
Features:
1. Flat bottom type: The bottom of the traditional gate valve is designed with a groove. After the water is passed through, the sundries such as stones, wood, cement, paper scraps, and other debris are easy to silt in the groove at the bottom of the valve. It is easy to cause failure to close tightly and form water leakage. The lower part of the soft-seal gate valve adopts the same flat-bottom design as the water pipe, which is not easy to cause debris to deposit and make the fluid flow unimpeded;
2. Overall encapsulation: The valve plate adopts high-quality rubber for integral inner and outer rubber. The domestic first-class rubber vulcanization technology enables the vulcanized valve plate to ensure accurate geometric dimensions, and the rubber and ductile iron gate are firmly connected, which is not easy Good shedding and elastic memory;
3. Corrosion resistance: the valve body is coated with powder epoxy resin, which can prevent corrosion and rust of the valve body, and can be used in sewage systems. Three "O" ring seals because the stem adopts three "O" ring seals, which can reduce frictional resistance when switching on and off, and greatly reduce water leakage;
4. Conducive to raw drinking: Since the inside of the valve body is coated with non-toxic epoxy resin, the inner and outer surfaces of the gate are completely covered with rubber to prevent rusty water or corrosion, which can be used for raw drinking;
5. Online replacement of valve shaft sealing ring: The valve shaft sealing part can be overhauled and replaced under the condition of normal water supply without stopping water.
