Electric single and bidirectional plug-in valve

Precautions and characteristics for the use of electric single and bidirectional plug-in valves: The opening and closing component of the plug-in valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. The plug-in valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate 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. The gate of the wedge type plug valve can be made as a whole, called a rigid gate; It can also be made into a gate plate 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 plate is called an elastic gate plate insert valve. When the valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface. This is called self sealing Most plug-in valves use forced sealing, which means that when the valve is closed, the gate must be forcefully pressed against the valve seat by external force to ensure the sealing surface is sealed.
