Penetrating type flat gate valve

Abstract

The invention discloses a penetrating type flat gate valve, and relates to the field of flat gate valves. The penetrating type flat gate valve comprises a valve body, an electric push rod and a connecting sleeve, wherein the valve body and the electric push rod are fixedly connected to the two ends of the connecting sleeve respectively, guide wheels are arranged on the periphery of the inner wallof the connecting sleeve, the guide wheels are slidably connected to the surface of a piston rod of the electric push rod, a guide sleeve is arranged at the inlet position of the valve body, and the surface of the piston rod of the electric push rod is movable sleeved with the guide sleeve. According to the penetrating type flat gate valve, a U-shaped movable frame, a limiting sleeve, a through-flow device, a sealing bearing, a communicating plug ,a through-flow hole and a gear ring are arranged, the problems are solved that for the penetrating type flat gate valve driven by the electric pushrod, the valve body can be opened and closed by the parallel movement of a closing part driven by the electric push rod in the linear direction, the moving stroke of the closing part is long, the usetime is long, and the impact on the gate valve when opening and closing by lifting speed is large is solved under the condition that rapid opening and closing are needed.

Description

technical field [0001] The invention relates to the technical field of slab gate valves, in particular to a penetrating slab gate valve. Background technique [0002] The penetrating slab gate valve is a valve body whose closing parts are parallel gates. The slab gate valve has three driving modes: manual slab gate valve, pneumatic slab gate valve and electric slab gate valve. The electric slab gate valve is generally driven by a motor or an electric push rod. During the use of the valve body, a certain amount of grease should be regularly injected into the valve body to maintain the valve body to ensure the service life of the valve body. [0003] The penetrating slab gate valve is generally connected between the pipelines when in use, and is connected with the pipeline through bolt flanges, so that the penetrating slab gate valve can control the flow of the medium in the pipeline. [0004] For the penetrating slab gate valve driven by the electric push rod, most of the cl...

AI Technical Summary

Problems solved by technology

[0004] For the penetrating slab gate valve driven by the electric push rod, most of the closing parts are driven by the electric push rod to move parallelly along the linear direction to realize the opening and closing of the valve body. The moving stroke of the closing part is longer and the time is longer. Under certain conditions, the impact on the gate valve is greater when opening and closing by increasing the speed. To solve the above problems, we provide a penetrating flat gate valve
