Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", and the like, indicate positional or positional relationships, are merely for convenience in describing the present invention and to simplify the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

As shown in fig. 1 to 4, a sealing connection device for water supply and drainage pipelines comprises a connecting pipe 1, two ends of the connecting pipe 1 are respectively provided with an annular slot 2, a sealing ring 3 with a cross section of a J-shaped shape is installed in the annular slot 2, a pressing block 4 extending along the axial direction of the connecting pipe 1 is arranged on the outer side wall of the annular slot 2 of the connecting pipe 1, an annular clamping sleeve 6 is sleeved outside the pressing block 4 at the same end of the connecting pipe 1, a circle of annular bulge 5 is arranged in the middle of the outer side of the connecting pipe 1, and the annular clamping sleeve 6 is connected with the annular bulge 5 through a fastener.

Through setting up connecting pipe 1, sealing washer 3, briquetting 4, annular arch 5, annular cutting ferrule 6, fastener cooperation, realize the assembled connection of tubular product, not only easy dismounting only needs the tubular product of replacement damage when the maintenance moreover, and the junction of the tubular product of damage and adjacent tubular product can not receive the destruction formula and demolishs, reduces the loss of tubular product.
