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...
