Electric wear-resisting ore pulp gate valve

Abstract

The invention discloses an electric wear-resisting ore pulp gate valve which is composed of a valve body, a gate plate, a support, a valve rod, a pressing plate and a sealing ring. An electric head is mounted on the support. The valve body is formed by buckling two symmetrical semi-valve bodies, and each semi-valve body is in a round-to-square funnel shape; the joints of the two ends of the valve body and pipelines are circular, an inner cavity located in a gate plate opening and closing position of the middle of the valve body is square, and therefore the inner cavity is changed into a square shape from a circular shape, the open area is enlarged, the flowing speed is reduced, and the purpose of reducing friction is achieved. The inner cavity of the valve body is covered with a fluorine lining, and a wear-resisting composite layer is arranged on the incident flow face of the gate plate. The wear-resisting composite layer can be made of special metal or rubber or cast stone. The fluorine lining is made of polyvinyl fluoride. Accordingly, the wear resistance of the gate valve is improved, and the service life of the gate valve is prolonged. The gate valve is electrically opened and closed, the labor intensity of workers is relieved, remote control is facilitated, and modern management is achieved. The wear resistance is high; due to the fact that the fluorine lining and the wear-resisting composite layer are additionally arranged, the easily-abraded portions of the whole gate valve are effectively protected, the wear resistance of the gate valve can be remarkably enhanced, the service life is prolonged, the maintenance and replacement frequency is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to a pipeline valve, in particular to an electric wear-resistant gate valve. 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.
