Description

Technical Field

[0001] This utility model relates to the technical field of quick gasket replacement tools, and in particular to quick gasket replacement tools for chemical pressure vessels. Background Technology

[0002] Quick-change tools for gaskets on chemical pressure vessels are tools specifically designed for the rapid and efficient removal and installation of gaskets on pressure vessels in chemical production. They are designed to be simple and easy to use, allowing operators to quickly master their operation after some training, reducing the difficulty and time required for gasket replacement and improving work efficiency.

[0003] However, existing quick-change tools for gaskets have the following disadvantages:

[0004] (1) When facing multiple devices that require gasket replacement, if it is difficult to disassemble and replace the replacement head of the replacement tool during the replacement process, it will affect the working time. An inconvenient replacement head will also increase the difficulty of the work.

[0005] (2) The gaskets of chemical pressure vessels may be installed deep, especially in some large or complex vessels. If it is difficult to extend the tool when changing tools, it may be inconvenient for operators to accurately deliver the tool to the location of the gasket, which increases the difficulty and complexity of the operation.

[0006] Therefore, this utility model provides a tool for quick replacement of gaskets for chemical pressure vessels. Utility Model Content
