Description

Coupling for pipe joint {A COUPLING FOR PIPING CONNECTION}

The present invention relates to a pipe joint coupling for interconnecting pipes.

In conventional pipe joint couplings, only the upper and lower couplings, which are mainly separated by the upper and lower semicircles, are assembled as bolts and nuts, which makes it difficult to assemble with horizontal accuracy of both pipes. It also had the drawback of leaking due to loose connections in small external flows.

In the present invention, in order to solve such defects, both ends of the a-type sockets formed with the upper and lower fastening ends and the semi-circular fastenings formed with grooves in the middle of the inner circumferential surface of the two ends, respectively, protruding from the ends of the joints of both pipes. One end of the three protrusions formed in the outer diameter passes through the middle recess of the outer circumferential outer side of the semicircular binding portion and is inserted into the groove, while the end of the joint is sealed into both sides of the packing fitted in both insertion grooves of the inner circumference of the socket. After inserting so as to correspond to the semi-circular fastening part, the semi-circular fastening ring of a separate object formed with a groove band in the middle of the upper and lower fastening ends and the inner circumferential surface. Tighten with bolts and nuts to insert two projections of the outer diameter of the joint The side portion of the pipe joint to be fixed on both sides of the socket when described in detail based on drawings as follows.

The packing 12 is inserted into both insertion grooves 11 of the inner circumference of the socket, and the upper and lower fastening ends 14 and 14a on one side of the left and right ends of both ends and the grooves 15 and 15a between the inner circumferential surfaces. Known ?? is formed to protrude each of the semi-circular binding portion (13, 13a) is formed In the socket 10, one of the three projections 2, 2a formed at the outer diameter of the joint portion at the end of the joint portions 1, 1a of both the pipes 1, 1a is formed in a semicircular shape. Passing through the intermediate recesses 17 and 17a of the outer peripheral protrusion strips 16 and 16a by the groove strips 15 and 15a in the middle of the inner circumferential surface of the binding portions 13 and 13a. 15) Insert the end of the joint into the both sides of the packing 12 of both the insertion grooves 11 of the inner circumference of the socket so that the end of the joint is inserted into the upper and lower parts so as to correspond to the semicircular binding parts 13 and 13a. Semi-circular binding ring 20 of a separate body having grooves 22 and 22a formed in the middle of the fastening ends 21 and 21a and the inner circumferential surface, and projection bands 23 and 23a formed on the inner circumference of the inner circumferential surface. 20a) grooves 18 and 18a formed on the outer circumferential surface of the socket tip portion to be in contact with the inner and outer protrusions 23 and 23a of the inner circumferential surface, and grooves 22 and 22a in the middle of the inner circumferential surface. The upper and lower fastening ends 21 of the two protrusions 2 and 2a of the ), (21a), (14) and (14a) are fastened with bolts and nuts, and the grooves 24 and 24a are formed inside the inner circumferential surface of the semicircular binding ring 20 and 20a and are in contact with the socket. (10) The outer circumferential surface of the distal end portion may be formed with projection bands 19 and 19a, respectively, so that the unevenness may be formed to be opposite to each other. (13a) may be formed in the same direction on both sides as necessary or in opposite directions opposite to each other.

And the pipe shape can be used as the pipe shape by forming the socket shape as-shape, and the pipe connection state can be used as the pipe shape as the pipe shape by forming the socket shape as the shape of the pipe shape.
