Embodiment Construction

[0006] The electric gate valve of the present invention is basically composed of a valve body, a gate plate, a bracket, a gate rod, a pressure plate, and a sealing ring. Its connection is the same as that of an ordinary gate valve. The valve body is snapped together, that is, the connection between the two ends of the valve body and the pipe is circular, and the middle connection is also the place where the gate is installed. shape. The cross-sectional area is enlarged at the installation place of the ram, and the flow velocity is slowed down to reduce the wear of the ram by the slurry.

Abstract

An objective of the invention is to provide an electric wear-resisting pulp gate valve, formed by a valve body, a flashboard, a support, a valve rod, a pressure plate, and a seal ring. The support is provided with an electric actuator. The valve body is formed by fastening two symmetric half-valve-bodies which are in a round-to-square funnel-shape. Two ends of the valve body, the end are connected with pipes, are round. The inner cavity on the on-off position of the flashboard on the middle of the valve body is square. Thus, the inner cavity converts to square from round, thereby increasing open area, reducing flowing speed, and achieving an objective of reducing wearing. The inner cavity of the valve body is covered by fluorine lining. The incident flow surface of the flashboard is provided with a wear-resisting composite layer. The wear-resisting composite layer can be special metal, rubber, or cast stones. The fluorine lining material is polyvinyl fluoride. Thus, wear resistance of the gate valve is enhanced, and service life is prolonged.

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. Contents of the invention [0003] In order to solve the problem o...
