AI Technical Summary

Technical Problem

Existing valve assembly and disassembly tools have limited functionality, and the disassembly and installation process is time-consuming and laborious, and can easily damage the valve body and valve.

Method used

A rapid cutting and disassembly device for valve rubber was designed, including a main support, a clamping mechanism, a cutting mechanism, and a pushing mechanism. The valve body is clamped and fixed, the cutting blade moves radially to cut the old rubber, and the new rubber is pushed and installed by the pushing mechanism.

Benefits of technology

It enables the quick disassembly of old valve sheets and the installation of new valve sheets, saving time and effort, improving work efficiency, enriching the functions of the tool, and reducing the use of human resources.

Abstract

This invention relates to the field of oil and gas field development equipment maintenance technology, and particularly to a rapid valve shearing and disassembly device, aiming to alleviate the technical problem of limited functionality in existing rapid valve shearing and disassembly devices. The rapid valve shearing and disassembly device includes a main support, a clamping mechanism, a shearing mechanism, and a pushing mechanism. The clamping mechanism is located on the main support and is used to clamp the valve body. The shearing mechanism includes a first drive assembly and a shearing blade. The first drive assembly is located on the main support and is connected to the shearing blade for driving the shearing blade to move radially along the valve body. The pushing mechanism is connected to the clamping mechanism and is used to push the valve to the valve body. This rapid valve shearing and disassembly device can both cut the valve to disassemble the old valve and push the valve to install the new valve, thus enriching the tool's functionality.
