5、 Application of electric elastic seat sealing gate valve

Elastic seat sealed gate valves are widely used as regulating and shut-off devices in fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, power, ships, metallurgy, energy systems, etc

6、 Characteristics of Electric Elastic Seat Sealed Gate Valve

1Flat bottomed valve seat, no accumulation of dirt, making the seal more reliable

2The valve disc is entirely wrapped in nitrile rubber,The valve internals are made of corrosion-resistant and rust resistant steel and copper alloy materials, which can be used in sewage systems to adapt to harsh working environments

3Small size, light weight, easy to install and maintain

4The valve stem adopts three channelsOThe ring seal greatly reduces the frictional resistance during switching, making the switch lightweight and leak proof.

7、 Advantages of Electric Elastic Seat Sealing Gate Valve

When the elastic seat seal gate valve is closed, the sealing surface can be sealed solely by the pressure of the medium,That is, relying solely on the pressure of the medium to press the sealing surface of the gate towards the valve seat on the other side to ensure the sealing of the sealing surface, this is called self sealing. mostPneumatic gate valveIt adopts forced sealing, that is, when the gate valve is closed, it needs to rely on external force to forcefully press the gate plate against the valve seat to ensure the sealing surface is sealed.

openelectric gate valveWhen the lifting height of the gate is equal to the diameter of the gate valve1：1At double the time, the fluid channel is completely unobstructed, but during operation, this position cannot be monitored. In actual use, the vertex of the valve stem is used as a marker, that is, the position where it cannot be opened, as its fully open position. To consider the occurrence of locking phenomenon due to temperature changes,Usually when driving to the vertex position,Reverse it again1/2-1circle,As the position for fully opening the gate valve. therefore,Fully open position of the gate valve, according to the position of the gate plate(Determine the itinerary. The sealing surface is prone to wear and tear, which affects its service life. When opening and closing, the two sealing surfaces of the gate and valve seat rub and slide against each other, which is prone to abrasion and wear under the pressure of the medium, affecting the sealing performance and shortening the service life.

For a long time, the general gate valves used in the market have generally suffered from water leakage or rusting. To overcome the defects of poor sealing and rusting of general gate valves, elastic seat seal gate valves use the compensating effect of slight elastic deformation generated by the elastic gate plate to achieve good sealing effect. They have significant advantages such as light switching, reliable sealing, good elastic memory, and service life. It can be widely used as a regulating and intercepting device on pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, energy systems, etc. This is the benefit and advantage of elastic seat sealed gate valves.
