Structural characteristics of electric gate valve

Simply put, the electric valve is to use an electric actuator to control the valve, so as to realize the opening and closing of the valve. It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. The action distance is larger than that of the electric valve. The switching speed of the electric gate valve can be adjusted. The structure is simple and easy to maintain. Due to the cushioning characteristics of the gas itself, it is not easy to be damaged due to jamming during the operation. However, it must have a gas source and its control system More complicated than electric valves. Electric gate valves are sensitive and reliable. Many factories with high control requirements set up compressed air stations for pneumatic instrument control components. Electric is a device that needs electricity and can control its flow.

①The valve adopts pressure self-tightening seal or valve body and bonnet gasket seal structure, which is trustworthy! Reliable in use.

②The valve disc adopts a double gate with a universal top structure in the middle, which can automatically adjust the fit between the valve disc and the sealing surface of the valve seat to ensure the sealing of the valve. At the same time, this structure is convenient to maintain, save costs, and has better valve disc interchangeability.

③The sealing surface of valve disc and valve seat is made of cobalt-chromium-tungsten cemented carbide by plasma spray welding. The sealing surface has high hardness, abrasion resistance, abrasion resistance and long service life.

④The valve stem is made of nitrided steel with surface nitriding treatment, high hardness, scratch resistance, corrosion resistance and long service life.

⑤The electric device is equipped with a torque control mechanism, an on-site operating mechanism, and a hand and electric switching mechanism. In addition to local operation, remote operation, PLC control, 4-20mA current input and output intelligent control, etc. can also be carried out.

⑥The manual valve is opened by the manual mechanism or the hand wheel upon impact. Reduce valve operating force.

⑦The valve can be installed in any position of the pipeline, and the carbon steel or alloy steel valve can be selected according to the temperature of the medium and the medium.

⑧When installing and debugging for the first time, the valve must be manually opened to about half of the position to avoid damage to the valve or electrical equipment due to the reverse connection of the motor phase sequence.
