Embodiment Construction

[0020] A method for compensating for expansion and contraction of building drainage pipes in this embodiment, the steps are: installing expansion compensators at the joints of drainage pipes to ensure that when the drainage pipes are heated and deformed and elongated, the elongation can pass through the expansion The compensator is compensated.

[0021] Such as Figure 1~5 As shown, the telescopic compensator in this embodiment includes a flange gland 3, a sealing rubber ring 4, fastening bolts 5, a telescopic compensator body 1 made by casting and a EPDM rubber material. The compensating rubber ring 2, the telescopic compensator body 1 is a cylinder body, the two ends of the telescopic compensator body 1 are provided with flanges 104, and the middle part of the telescopic compensator body 1 is provided with a compensating rubber ring installation groove 102 , the compensation rubber ring compensation groove 101 is provided in the middle of the compensation rubber ring instal...

Abstract

The invention relates to a flexible compensation method and a flexible compensator for a building drainage pipeline, and mainly aims to solve the technical problems of poor corrosion resistance, short service life, easiness in axis deflection of a vertical pipe, easiness in blockage of the pipeline by fiber pollutants, poor drainage performance and incapability of matching a connection way with a cast iron drainage pipe interface in the conventional pipeline compensator. The flexible compensator is arranged on a joint between drainage pipelines in order to ensure that the elongation amount can be compensated through the flexible compensation when the drainage pipelines are deformed in an extending way in a heating way. The flexible compensation method and the flexible compensator have the advantages of high corrosion resistance, long service life, prevention of axis deflection of the vertical pipe, prevention of blockage of the pipeline by the fiber pollutants, high drainage performance, and matching between the connection form and the cast iron drainage interface.

Description

technical field [0001] The invention relates to a stretch compensation method and a stretch compensator for a building drainage pipeline, which belong to a method and a device for compensating the expansion and contraction of the pipeline due to cold and heat deformation in a cast iron drainage pipeline, and preventing the pipeline from being damaged by deformation stress or leaking at the interface. Background technique [0002] The compensator is also called the expansion joint or the expansion joint, and it is mainly used to compensate the thermal expansion and contraction of the pipeline caused by the temperature change. If the pipe is not completely free to expand or contract when the temperature changes, thermal stresses will develop in the pipe. And this thermal stress will lead to the rupture of the pipeline, affecting the normal production. The compensator can compensate the deformation or displacement of the pipeline to prevent the pipeline from cracking due to th...
