Abstract

The invention provides a quick assembly tool for valve seat support, which includes a wrench assembly and a drive assembly. The drive assembly is used to install the valve seat support on the valve body. The rod part is also covered with a positioning disc, which is in contact with the valve body channel on the valve body. The driving head at the front end of the wrench assembly acts on the driving assembly, and the driving assembly drives the valve seat support to rotate, so that the valve seat support is threaded into the valve body. . The valve seat support quick assembly tooling of the present invention absorbs the sliding block set in the bottom plate made of ceramic material through the magnetic steel block on the inner wrench, ensures the connection between the wrench assembly and the drive assembly, and drives the valve seat support through the drive key The thread is tightly connected to the valve body.

Description

technical field

[0001] The invention relates to the field of valve assembly, in particular to a quick assembly tool for valve seat support. Background technique

[0002] The valve seat support is the key sealing part in the valve body cavity, and it forms a sealing pair with the ball to realize the sealing function of the valve. At the same time, there should be good sealing performance between the valve seat support and the valve body. The valve seat support assembly tool is a tool for installing the valve seat support in the inner cavity of the valve body. For valves in which the seat support in the valve body cavity is threadedly connected to the valve body, there are double sealing ring structures between the outer circle of the seat support and the valve body, which are respectively located on the end surface and outer circle of the seat support. When the seat support is screwed into the valve body from the lower end of the valve body, it must overcome the huge fricti...
