Rail type horizontally-installed gate valve structure

Abstract

The invention discloses a rail type horizontally-installed gate valve structure, and relates to the field of gate valves, the rail type horizontally-installed gate valve structure comprises a valve body, a valve rod and a gate plate, the gate plate is connected with the end, inserted into the valve body, of the valve rod, grooves are formed in the two sides of the interior of the valve body, guide rails are arranged in the grooves and are parallel to the valve rod, and rolling wheels running along the guide rails are arranged on the circumferential walls of the two sides of the gate plate. According to the gate valve, sliding friction between the gate plate and the valve body is converted into rolling friction through matched arrangement of the guide rails and the rolling wheels, the friction loss between the gate plate and the valve body is improved to a large extent, and the service life of the gate valve is prolonged.

Description

technical field [0001] The present application relates to the field of gate valves, in particular to an orbital horizontal gate valve structure. Background technique [0002] The gate valve is a gate of the opening and closing part. The movement direction of the gate is perpendicular to the direction of the fluid. It is sealed by the contact between the gate and the valve seat on the medium channel of the valve body. It can only be fully opened and fully closed, and cannot be adjusted and closed. throttling. As a general equipment for controlling the opening and closing of fluid pipelines, gate valves are widely used in water supply and drainage, sewage treatment, food, medicine, industrial and mining, chemical industry, metallurgy and other industries. [0003] Due to the large opening and closing stroke of the gate plate, the volume of the gate valve is relatively large compared with other valves. Therefore, in some occasions with limited space and height, large-diameter ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor found that during the opening and closing process, the gate moves along the guide ribs of the valve body, and the frictional resistance between the gate limit groove and the guide ribs of the valve body is obvious when the gate valve is installed horizontally. Increased, resulting in wear and tear on the gate and valve body, affecting the service life of the gate valve
