Problems solved by technology
[0004] The purpose of the present invention is to provide an easy-to-replace mechanical seal assembly for metal bellows connection, so as to solve the problem that the existing mechanical seal assembly for metal bellows connection proposed in the background art is difficult to disassemble quickly when it is used. Moreover, after the mechanical seal assembly is used for a long time, the inside will be blocked. The general mechanical seal assembly cannot monitor the blockage, and it is not convenient to clean or replace it in time.

The invention discloses an easy-to-replace mechanical seal assembly for metal bellows connection, comprising a first metal bellows, a second metal bellows and a mechanical seal assembly body, the right side of the first metal bellows and the second metal bellows Fixing parts are fixed on the left side of the pipe, a second metal bellows is arranged on the right side of the first metal bellows, a first liquid flow monitor is arranged inside the first connecting pipe, and a first liquid flow monitor is arranged inside the second connecting pipe. There is a second liquid flow monitor, and bolts are arranged on one side of the first sealing ring. The easy-to-replace mechanical seal assembly for metal bellows connection is provided with a first sealing ring and a second sealing ring. The first connecting pipe, the second connecting pipe and the second sealing ring form a disassembly and installation structure. The connection between the first connecting pipe and the second connecting pipe and the body of the mechanical seal assembly can be sealed to prevent leakage of the body of the mechanical seal assembly.
Description
technical field [0001] The invention relates to the technical field of metal bellows, in particular to an easy-to-replace mechanical seal assembly for connecting metal bellows. Background technique [0002] Metal bellows is a pipe that looks like a regular wave. Commonly used metal bellows include carbon steel and stainless steel, as well as steel-lined plastic and aluminum. It is mainly used for non-concentric axial transmission with small bending radius, or irregular turning, expansion and contraction, or absorbing thermal deformation of pipelines, etc., or it is not convenient to use fixed elbows to connect pipelines, or to connect pipelines with pipelines. device connection. [0003] It is difficult to quickly disassemble the existing mechanical seal assembly for metal bellows connection, and after the mechanical seal assembly has been used for a long time, the inside will be clogged, and the general mechanical seal assembly cannot monitor the clogging situation , it i...
