SU25820A1 - Method of connecting water pipes - Google Patents

Description

To speed up the laying of pipelines, in this method of connecting water pipes, an annular valve device is provided inside one of the ends of each link. The valve is composed of a strip of roofing iron with notches along the free rim, riveted with another rim to the inner surface of the pipe using a gasket. The end of the counter link is inserted into the groove formed by the valve and the pipe.

In FIG. 1 shows a longitudinal section of the junction with a bell; FIG. 2 is the same for connecting pipes without socket.

To connect the ends of the pipes 2 and 3 with the water flow direction shown by the arrow in FIG. 1, a roofing iron band is riveted on the inside of the pipe 2 having a socket at the end, forming the sleeve 1 so that the free rim of this sleeve, provided with notches, is facing towards the opposite link 3 and together with the internal surface of the link 2 forms an annular groove, into which the end of the link 3 can be inserted. In the case of connecting pipes that do not have a plug at the end of the socket. 2), sleeve 1 is withdrawn free

a rim beyond the end of the pipe, to which it is riveted, and protruding it is inserted inside the counter pipe. To seal the joint between the sleeve 1 and the surface of the pipe 2, a gasket 4 is used, and from the outside both pipes are connected by hooks or grips 5 which engage with corresponding protrusions on the surface of the pipes.

The flow of water in the direction indicated by the arrows must press the free rim of the sleeve 1 against the inner surface of the opposite link and thus ensure the tightness of the joint.

The subject matter of the invention.

1. A device for connecting water pipes, characterized by the use in the broadened end of pipe 2 (Fig. 1) of an internal, with incisions along the free rim, of a sleeve 1 made of roofing iron riveted to the end of the pipe, forming an annular, end groove with the latter and representing an annular valve that covers the inner side of an annular gap formed by the end of the attached pipe 3 being inserted into the specified groove. 2. The form of the device according to claim 2, characterized in application, to obtain a tighter and stronger joint, is sealing gasket 4 on sleeve 1 (Fig. 1) and external contractions or hooks 5. 3. Modifying the device according to claim 1., characterized in that the end of the outer pipe does not expand (Fig. 2), and the internal sleeve with a sealing the gasket forms a protruding bezel inserted into the end of the closed pipe ..
