Description

Technical Field

[0001] This utility model relates to the field of sealing valve technology, specifically a limit sealing valve with a telescopic adjustment structure. Background Technology

[0002] A gate valve is an opening and closing element consisting of a gate. The direction of the gate's movement is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling. Gate valves achieve sealing through the contact between the valve seat and the gate. Typically, the sealing surface is overlaid with a metal material to increase wear resistance, such as 1Cr13, STL6, or stainless steel.

[0003] An existing airtight gate valve, CN202110865334.5, has a lifting step that is slightly higher than the left and right guide grooves. After the gate valve is closed, it lifts up, improving the sealing effect. However, it has shortcomings: the installation support height of the existing equipment cannot be adjusted, and the limiting and sealing effects are not good. Moreover, the connection stability and opening and closing stability are not good, resulting in poor performance. Therefore, a limit-sealing valve with a telescopic adjustment structure is needed to solve the above problems. Utility Model Content
