A stop valve with internal cleaning structure

Abstract

The utility model discloses a stop valve with an internal cleaning structure, comprising a valve body, a valve cover fixedly connected to the top of the valve body, an adjustment seat fixedly connected to the top of the valve cover, and a valve stem meshed inside the adjustment seat. The utility model drives the connection seat to rotate and move in the process of closing and opening the sealing bolt by rotating the valve stem, thereby driving the cleaning ring to perform friction cleaning in the upper half of the valve body. After the valve body is opened, water flows into the interior of the valve body through the water inlet and continuously impacts the fan blades through the sealing plate. Under the impact of the water flow, the fan blades rotate to drive the rotating shaft to rotate, thereby driving four cleaning mechanisms to brush around the surface of the lower half of the valve body, thereby cleaning the inside of the stop valve, avoiding disassembly and cleaning of the stop valve, improving the cleaning efficiency and not interrupting the operation of the entire pipeline system due to cleaning.

Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a stop valve with an internal cleaning structure. Background Art

[0002] A stop valve is usually composed of a valve body, a valve disc and a valve stem for driving the valve disc to move up and down linearly. The valve body is provided with an isolation inner wall with an opening. The two sides of the isolation inner wall constitute an inlet cavity and an outlet cavity respectively. The inlet cavity and the outlet cavity are connected to each other through the opening. The valve stem includes an internal part placed inside the valve body and an external part exposed outside the valve body. The other end of the internal part of the valve body relative to the external part is linked to the valve disc. The valve disc is placed at the conducting point between the inlet cavity and the outlet cavity and can be arranged in contact with the isolation inner wall to form a sealed connection.
