Structural characteristics of electric gate valve ①The valve adopts pressure self-tightening seal or valve body and valve cover gasket sealing structure, which is trustworthy! Safe and reliable to use. ②The valve disc adopts the structure of double gate with a universal top 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, the structure is easy to maintain, saves costs, and has good valve disc interchangeability. ③The sealing surface of valve disc and valve seat is made of cobalt-chromium-tungsten 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, the surface is nitrided, with high hardness, scratch resistance, corrosion resistance and long service life. ⑤The electric device is equipped with torque control mechanism, on-site operating mechanism and hand-electric switching mechanism. In addition to local operation, it can also perform remote operation, PLC control, 4~20mA current input and output intelligent control, etc. ⑥ The manual valve is opened by the manual mechanism or the handwheel when it hits. 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 medium and the temperature of the medium. ⑧ During the initial installation and debugging, the valve must be manually opened to about half of the position, so as to avoid the reverse connection of the motor phase sequence and cause damage to the valve or electrical equipment.
