Soft seal groove gate valve features

The groove soft sealing gate valve is light in weight, and the body is made of high-grade ductile iron. The weight is about 20-30% lighter than that of the traditional gate valve, and the installation and maintenance are convenient. Conventional gate valves are often deposited in the groove of the valve bottom due to foreign objects such as stones, wood blocks, cement, iron filings, and debris after the water is washed. It is easy to cause the water to leak tightly and the water leakage is formed. The same flat bottom design as the water pipe is not easy to cause debris accumulation, so that the fluid is unobstructed.

The grooved bright rod soft sealing gate valve adopts a new type of steel pipe connection, also called clamp connection, which has many advantages. The design specification of automatic sprinkler system proposes that the connection of the system piping should be connected by grooved joints or threaded and flanged joints; for pipes with a diameter equal to or greater than 100mm in the system, flanges or grooved joints should be used in sections. connection.

The bright rod sealing seat valve is also called the lifting rod gate valve. Usually there is a trapezoidal thread on the lifting rod, and the rotary motion is changed into a linear motion by the nut at the top end of the valve and the guide groove on the valve body, that is, the operating torque is changed to the operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 times the diameter of the valve, the passage of the fluid is completely unblocked, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a mark, that is, the position where the valve is opened, as its fully open position. In order to consider the temperature change, the lock phenomenon is usually turned on to the apex position, and then back to 1/2-1 turn as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the shutter (ie stroke).

The elastic seat sealing gate valve is also called soft sealing gate valve. It adopts the whole rubber encapsulation of the valve to produce deformation compensation effect to achieve a good sealing effect, and overcomes the phenomenon of poor sealing, water leakage and rust of the general gate valve, and more effectively saves installation space. It can be widely used as a regulating and intercepting device on fluid pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system.

The grooved soft seal gate valve has six major features:

1. All specifications, large inventory, fast delivery, low price, is your ideal first product.

2. Structural Science: Flat Design.

The bottom of the groove soft sealing gate valve adopts the same flat bottom design as the water pipe, which is not easy to cause debris accumulation, so that the fluid is unobstructed.

3. Gate rubber: The whole gate is covered with rubber. It is made of high quality rubber and has good elasticity! Durable.

4. Shell material: made of precision ductile iron, once formed.

Traditional cast iron gate valves often cause breakage due to foreign objects hitting, collision or heavy pressure. Since Hebei Hongqiu valve soft seal gate valve body is changed to ductile iron, this situation can be greatly reduced.

5. The valve body is sprayed with 5005, the coating thickness is not less than 250μm. It can prevent corrosion and rust of the valve body and can be used in sewage system.

6. The internal structure of the open-bar groove soft sealing gate valve is accurate in size. The precise geometrical dimensions allow the valve body to be sealed without any finishing.
