Introduction

 

Soft seal gate valve, industrial valve, the opening and closing part of soft seal gate valve is the gate. The movement direction of the gate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, not adjusted and throttled. The ram has two sealing surfaces. The two sealing surfaces of the most commonly used Mode RAM valve form a wedge, and the wedge angle varies with the valve parameters. The nominal diameter is DN50 ~ DN1200, and the service temperature: ≤ 200 ℃.

 

Product principle

 

 

The gate of wedge gate valve can be made into a whole, which is called steel gate valve; It can also be made into a ram that can produce slight deformation to improve its manufacturability and make up for the deviation of the angle of the sealing surface in the processing process. This kind of ram is called elastic ram.

Soft seal gate valves are divided into rising stem soft seal gate valves and Non rising stem soft seal gate valves. Generally, there are trapezoidal threads on the lifting rod. Through the nut in the middle of the ram and the guide groove on the valve body, the rotary motion is changed into linear motion, that is, the operating torque is changed into operating thrust. When the valve is opened, when the lifting height of the ram is equal to 1:1 times the valve diameter, the fluid channel is completely unblocked, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as the mark, that is, the position that cannot be opened is used as its fully open position. In order to consider the locking phenomenon caused by temperature change, it is usually opened to the peak position and then turned back 1 / 2-1 turn as the position of fully open valve. Therefore, the full open position of the valve shall be determined according to the position of the RAM (i.e. stroke). This kind of valve shall generally be installed horizontally in the pipeline
