Elastic seat gate valve product introduction: 
 
For a long time, the general gate valve used in the market generally has the phenomenon of water leakage or rust. Shanghai Wootto Valve Factory introduced the European high-tech rubber and valve manufacturing technology of the elastic seat seal valve, to overcome the general valve seal defects, rust and other defects The elastic seat sealing gate valve uses the elastic gate to produce a slight amount of elastic deformation compensation to achieve a good sealing effect. The valve has the advantages of lightweight switch, reliable sealing, excellent elastic memory and useful life. 
 
The opening and closing part of the elastic seat gate valve is a gate plate. The movement direction of the gate plate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The concealed rod elastic seat sealing gate valve utilizes the overall encapsulation of the valve to produce a deformation compensation effect to achieve a good sealing effect, overcomes the general phenomenon that the gate valve is poorly sealed, leaks water and rust, and saves installation space more effectively. Soft-sealed gate valves can be widely used as regulating and shut-off devices in fluid lines such as tap water, sewage, construction, petroleum, chemicals, food, medicine, textile, power, marine, metallurgy, and energy systems. 
 
When the valve is opened, when the lifting height of the gate is equal to 1:1 of the valve diameter, the channel of the fluid is completely open, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a mark, that is, a position that does not move, as its fully open position. In order to consider the phenomenon of lock-up temperature change, usually in the open to the top position, and then rewind 1/2-1 lap, as a fully open valve position. Therefore, the fully open position of the valve is determined by the position of the gate (ie stroke). 
 
The working pressure of the elastic seat gate valve requires ≥ the working pressure of the pipeline. Under the premise of not affecting the price, the working pressure of the valve can be greater than the actual working pressure of the pipeline; any side of the soft sealing gate closed should be able to withstand 1.1 times the valve pressure without leakage; valve open conditions, the valve body should be able to withstand the requirements of double the valve pressure. 
 
Application range: 
 
Flexible seat sealing gate valve is especially suitable for drinking water system, food and pharmaceutical industry, industrial water supply and drainage and sewage treatment, natural gas and gas, soft seal gate valve can also be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine , textile, power, shipping, metallurgy, energy systems and other fluid lines. 
 
Structural features: 
 
Flat seat 
 
The bottom of the soft seal gate valve adopts the entire basin straight-through design without stagnant flow cavity structure to ensure the fluid flow and does not cause secondary pollution to the medium. 
 
Full-cover shutter 
 
The gate plate adopts ductile iron QT500-7 frame as a whole to cover high-performance rubber. Mature vulcanization technology and advanced vulcanization technology thoroughly isolate the gate iron core from the fluid. The coating is tight and reliable, and its bonding strength conforms to the requirements of DVGW. Even if subjected to frequent squeezing stress, the rubber will not fall off. 
 
The two-body structure of the stem nut and the gate plate ensures sufficient freedom, flexibility in opening and closing and no jamming. 
 
Reliable upper seal 
 
The upper seal between the valve stem and the top cover adopts five [O" seal ring structures of [inner 3 and outer 2". Compared with the packing and sealing structure of traditional gate valves, the seal is tight and reliable, and friction resistance is greatly reduced. 
 
Anti-corrosion performance 
 
Electrostatic spraying of epoxy powder on the inner and outer surfaces of the shell (ball-ductile QT500-7) ensures a uniform and firm coating with no exposed iron. The middle cavity attaches the top seal of the bolts and isolates the bolts from contact with the environment to prevent corrosion.
