The 10K Resilient Seat Gate Valve has two sealing faces. The two sealing faces of the most common mode gate valves form a wedge shape, and the wedge angle varies with valve parameters. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its process-ability and compensate for the deviation of the sealing surface angle during the machining process. The board is called a resilient shutter.
The elastic seat sealing gate 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, there is a lock-up phenomenon, usually at the position of the opening to the apex, and then back to 1/2-1 lap as the position of the fully open valve. Therefore, the fully open position of the valve is determined by the position of the shutter.
