A kind of pipeline micro expansion and contraction mechanism for water supply equipment and using method thereof

Abstract

The invention relates to a pipeline micro expansion and contraction mechanism for water supply equipment and a method of using the same. At the connection end of the fixed pipeline, corresponding locking bolts are respectively connected between the first connection hole of the pipeline flange and the second connection hole of the positioning pipeline flange; The fixed convex edge at the edge of the inner hole of the positioning pipeline flange, a corresponding telescopic flange is sleeved on the fixed convex edge, and the bottom surface of the telescopic flange is fixed on the positioning pipeline flange. Tightening bolts for jacking; sealing gaskets, installed between the expansion flange and the pipeline flange; side sealing rings, squeezed between the sealing groove of the expansion flange and the outer side wall of the fixed flange. between. The invention has simple structure, low cost, low space occupation, convenient installation and easy operation.

Description

technical field [0001] The invention relates to a pipe micro-expansion mechanism for water supply equipment and a method of using the same. Background technique [0002] With the advancement of urbanization, the city is getting bigger and bigger, and the pressure of the residential quarters where the tap water pressure can meet the demand has dropped. Pressurized water supply equipment began to be widely used. [0003] When the existing water supply pipeline for water supply equipment is connected, a water supply pipeline often contains various pipe fittings, valves and other components. The axial installation distance of the water supply pipeline needs to be able to achieve micro-adjustment, so as to realize the convenient disassembly and assembly of pipe fittings, valves and other components on the basis of not affecting the airtightness of the pipeline installation. At present, most of the axial micro expansion and contraction mechanisms of pipelines are metal bellows w...

Problems solved by technology

[0004] The use of metal bellows is not only expensive, but in order to achieve sufficient stretching / compression, the length of the metal bellows is required to be high, resulting in a substantial increase in space occupation; moreover, it requires high technical requirements for installation and construction, and the installation is labor-intensive; One is that the inner wall of the bellows will block the water flow, resulting in the loss of water flow
