Working principle of open stem elastic seat sealing gate valve

The opening and closing component of the open stem elastic seat seal gate valve is the gate plate, and the movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces that form a wedge shape. The wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, the gate of the wedge gate valve can be made as a whole, called a rigid gate valve; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate. This type of valve should generally be installed horizontally in pipelines.

Introduction to the Function of Bright Rod Elastic Seat Sealing Gate Valve

Rising stem elastic seat seal gate valve, also known as lifting stem gate valve (also known as rising stem gate valve). Usually, there are trapezoidal threads on the lifting rod, which convert rotational motion into linear motion through the nut at the top of the valve and the guide groove on the valve body, that is, convert operating torque into operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 times the valve diameter, the fluid channel is completely unobstructed, but this position cannot be monitored during operation. 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 phenomenon of locking due to temperature changes, it is usually done by opening the valve to the top position and then reversing it back, 1/2-1 turn, as the position for fully opening the valve. Therefore, the fully open position of the valve is determined by the position of the gate (i.e. stroke).
