Product Description

Soft Seal Gate Valve

The opening and closing parts of the soft seal gate valve, industrial valve and soft seal gate valve are gate plates. The direction of the motion of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and can not be adjusted and throttle. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges and wedge angles that vary with the parameters of the valve, usually 50 and 2 52''''when the medium is not high.
Product principle

The sluice gate of a wedge valve can be made into a whole, called a steel gate, or a sluice which can produce a small amount of deformation to improve its craft and make up for the deviation produced by the angle of the seal in the process of processing. This gate is called an elastic gate.

Soft sealed butterfly valve

The soft seal gate valves are divided into two types: the open gate soft seal gate valve and the hidden rod soft seal gate valve. Usually there are trapezoid threads on the lifting rod. Through the nut in the middle of the gate and the guide slot on the valve body, the rotation motion is turned into a straight motion, which is to turn the operating torque into an operating thrust. When the valve is opened, when the height of the gate is equal to the 1:1 times of the valve's path, the passage of the fluid is completely unimpeded, but the position is not monitored during operation. The actual use is based on the vertex of the stem as a sign, that is, the location of the open position as its full open position. In order to consider the lock up phenomenon of temperature change, the 1/2 1 circle is usually returned to the top position as the position of the full open valve. Therefore, the full opening position of the valve is determined according to the location of the gate. Valves of this type should be installed horizontally in pipes.

Electric soft seal gate valve

General requirements
1, the specifications and categories of soft sealing gate valves should meet the requirements of piping design documents.
2, the type of the soft seal gate valve should be marked with the GB number requirement. If the enterprise standard, should specify the relevant description of the model.
3, the working pressure of the soft seal gate valve requires that the working pressure of the pipe is greater than that of the pipe. Under the premise of not affecting the price, the valve can bear the working pressure more than the actual working pressure of the pipe. The valve should be able to withstand 1.1 times the valve pressure value on any side under the closed condition of the soft seal gate valve without leakage; the valve body should be able to bear two times the valve under the valve opening condition. The requirement of gate pressure.
4, the manufacturing standards for soft sealing gate valves should be based on the national standard number. If the enterprise standard, the procurement contract should be accompanied by enterprise documents.
