Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a gate valve that facilitates filtration. Background Technology

[0002] A gate valve is a type of valve in which the opening and closing element (gate) moves perpendicular to the centerline of the passage. It is mainly used for fully opening and fully closing in pipelines and cannot be used for regulation and throttling. The direction of movement of the gate is perpendicular to the direction of fluid flow. The opening and closing of the passage is controlled by changing the relative position between the gate and the valve seat.

[0003] The working principle of a gate valve: When the valve needs to be opened, the operating mechanism drives the valve stem to move upward, which in turn drives the gate to move upward. As the gate rises, the fluid passage gradually opens, and the fluid can flow in from the valve inlet, pass through the filter device, and then flow out from the outlet. When the valve needs to be closed, the operating mechanism drives the valve stem to move downward, which pushes the gate to move downward, so that the gate and the valve seat fit tightly together to form a sealing surface, thereby cutting off the fluid passage and preventing the fluid from flowing.

[0004] In existing convenient gate valves, the filter screen is directly fixed inside the gate valve, usually using bolts or other structures for fixation. Although this fixing method is simple, after long-term use, impurities can easily clog the filter screen. When the filter screen is clogged with impurities, the entire valve needs to be disassembled for cleaning, which is a cumbersome, time-consuming and labor-intensive process. Utility Model Content
