AI Technical Summary
The gate of the existing gate valve wears out severely after repeated opening and closing, leading to leakage at the sealing surface and reducing the service life of the valve. It cannot meet the usage requirements, especially in working conditions where replacement is difficult or inconvenient.
It adopts a structure of large-hole gate and small-hole gate, and provides compensation force through spring. After the two gates are installed, they are set in a wedge shape to reduce wear and provide sealing compensation after wear.
It effectively reduces gate wear, extends valve service life, achieves sealing compensation, and improves the durability of gate valves.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to valve technical field, specifically is a sealing compensation's gate valve gate board. BACKGROUND
[0002] Gate valve is one of the most common valve types in pipeline, the movement direction of gate board is perpendicular to fluid direction, and the gate valve can only be fully opened and closed, the gate valve seals through the contact between valve seat and gate board, and the sealing surface is usually built up with metal material to increase wear resistance. The current common gate valve plate is fixedly connected to the valve rod, after the gate valve is opened and closed for many times, the wear of the gate board is relatively serious, which can easily cause leakage and reduce the service life of the valve, and the valve cannot meet the use under some conditions that are not easy to replace or inconvenient to replace. SUMMARY
[0003] In view of the above problems, the utility model provides a sealing compensation's gate valve gate board, which can reduce the wear of the gate board sealing surface, and can compensate for the sealing after wear, thereby prolonging the service life of the valve.
[0004] To achieve the above object, the utility model provides the following technical scheme: a sealing compensation's gate valve gate board, comprising: a large-hole gate board, a small-hole gate board, a valve shaft and a spring, the back surface of the large-hole gate board sealing surface is a large hole, the back surface of the small-hole gate board sealing surface is a small hole, the small hole in the back surface of the small-hole gate board can be inserted into the large hole in the back surface of the large-hole gate board, a spring is arranged between the large-hole gate board and the small-hole gate board to provide compensation force for the two gate boards, and the two gate boards are installed in the gate board mounting hole of the valve shaft.
[0005] Further, the large-hole gate board and the small-hole gate board are installed in place, and the two sealing surfaces are wedge-shaped and have a certain angle.
[0006] The utility model has the advantages that the spring can reduce the wear of the gate board, and can compensate for the sealing after the wear of the gate board sealing, thereby prolonging the service life. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 The utility model is a structural schematic view.
[0008] In the drawing, the serial number names are as follows: 1. Large-hole gate board 2. Small-hole gate board 3. Spring 4. Valve shaft. DETAILED DESCRIPTION
[0009] In order to make the purpose, technical scheme of the utility model more clear and explicit, the utility model will be further described below in combination with the drawings.
[0010] A kind of sealing compensation gate valve gate board, including: big hole gate board 1, small hole gate board 2, spring 3, valve shaft 4, the back of the sealing surface of the big hole gate board 1 is a big hole, the back of the sealing surface of the small hole gate board 2 is a small hole, the small hole of the back of the small hole gate board 2 can be inserted into the big hole of the back of the big hole gate board 1, the face of two gate boards after installation has certain angle, there is a spring 3 between the big hole gate board 1 and the small hole gate board 2, provides compensation force for two gate boards, two gate boards are installed in the gate board installation hole of valve shaft 4.
