Electric gate valve

Abstract

The invention discloses an electric gate valve composed of a valve body, a gate plate, a support, a valve rod, a pressing plate and a sealing ring. An electric head is installed on the support; the valve body is formed by buckling two symmetric half valve bodies in a round-to-square funnel shape, that is, the connecting positions of the two ends of the valve body and a pipeline are round, an inner cavity in the gate plate opening and closing position in the middle of the valve body is square, in this way, the inner cavity is changed from round to square, the overflowing area is expanded, the overflowing speed is reduced, and therefore the purpose of relieving abrasion is achieved. The inner cavity of the valve body is covered with tefulong, an abrasion-resisting composite layer is arranged on the flow surface of the gate plate, and the abrasion-resisting composite layer can be made of special metal or rubber or cast stone. The tefulong material is polyvinyl fluoride, so that abrasion resistance of the gate valve is enhanced, and the service life of the gate valve is prolonged. The gate valve is electrically switched on or off, so that labor intensity of workers is reduced, remote control is convenient, and modern management is realized. The gate valve is high in abrasion resistance; due to the fact that the tefulong and the abrasion-resisting composite layer are additionally arranged, the easy-to-abrade part of the whole gate valve is effectively protected, the abrasion resistance of the gate valve can be remarkably enhanced, the service life of the gate valve can be prolonged, maintenance and replacement can be reduced, and production efficiency can be improved.

Description

technical field [0001] The invention relates to pipeline valves, especially electric gate valves. Background technique [0002] Slurry gate valves are mainly used in fluid conveying pipelines with materials such as mine concentrators. At present, most of them are manual types, which require workers to operate on site. It is very inconvenient to open and close frequently, and the labor intensity of workers is high. Especially if the gate valve is installed in Inconvenient traffic or dangerous special places have potential safety hazards; it is not conducive to remote control and modern management, and it is impossible to realize simultaneous opening and closing of multiple gates. Because the slurry gate valve is used to transport the fluid loaded with materials (such as iron ore powder, etc.), the wear is very serious, and maintenance and replacement are difficult and time-consuming.
