The electric butterfly valve belongs to one of the electric valves and electric regulating valves. The main connection modes are flange type and wafer type. It is an important execution unit in the field of industrial automation control? Q: The difference between butterfly valve and gate valve?? Answer:? Butterfly valve refers to a kind of valve whose closing part (butterfly plate) is a disc, which rotates around the valve shaft to open and close. It mainly plays the role of cutting off and throttling on the pipeline. The opening and closing part of butterfly valve is a disc shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Precautions and model of knife gate valve product in use: the opening and closing part of knife gate valve is the gate, and the movement direction of the gate is perpendicular to the fluid direction. Manual knife gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valve form a wedge shape, and the wedge angle varies with the valve parameters, usually 50. The gate of the wedge knife gate valve can be made into a whole, called a rigid gate; It can also be made into a ram that can produce slight deformation to improve its processability and make up for the deviation of the angle of the sealing surface during processing. This kind of ram is called elastic ram. When the knife gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the ram is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self sealing. Most knife gate valves adopt forced sealing, that is, when the valve is closed, the gate plate should be forced to the valve seat by external force to ensure the sealing surface tightness. This type of valve should be installed horizontally in the pipeline.
