Description

A coupling for piping connection

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

Conventional pipe joint coupling inserts the circular packing into the middle inner circumferential groove of the upper and lower coupling mainly separating the joint parts of both pipes in the upper and lower semicircular shape, and insert the joint parts of the pipe from both sides around the packing. After assembling the upper and lower couplings as bolts and nuts, it was difficult to assemble with the horizontal accuracy of both pipes, and it took a lot of work time.

In the present invention, in order to solve these defects, the upper and lower fastening ends are divided into two, and the upper and lower fastening ends are divided into two and two fastening holes for binding the wheels formed at the outer diameters of the pipe joints at each end of the socket. In order to form the protruding fasteners, separate the fasteners of the circular body into the left and right fasteners of the semicircular body. The bolt holes of the upper and lower protruding joints are joined in a circular shape so that the bolt holes of the upper and lower protruding ends are inserted into the packings fitted into the insertion grooves of the inner circumference of the socket as the pipe joints. Fasten the joints of the pipes to the socket by fastening the bolt holes at the upper and lower ends of the socket as bolts and nuts. If the description follows:

The thicknesses of the upper and lower fastening ends 21, 22, 31, and 32 are divided into two parts, and the upper and lower fastening ends 21a, 22a, 31a, which are opposite to each other in the upper and lower parts. Left and right fasteners 20 and 30 which separate the fasteners of the circular body into semicircular bodies so as to form 32a, and the wheels 2 and 2a formed at the outer diameters of the pipes 1 and 1a. To the grooves 23 and 33 of the inner circumference, respectively, so that the half-tight protrusions 21a, 22a, 31a and 32a of the left and right fastening holes 20 and 30 are respectively inserted. After the bolts are joined together in a circular shape, the packings are closely attached to the rear connection parts 24 and 34 while inserting them into the packing 14 fitted in the insertion groove 13 of the inner circumference of the socket 10 as the joint part of the pipe. The bolt holes of the upper and lower protruding fastening ends 21a, 22a, 31a, and 33a and the upper and lower fastening ends 11 and 12 of the sockets of the sockets are It is made by tightening as a nut.

And by forming the socket 10 in the a-type pipe connection state can be used as the a-type pipe joint type, the socket 10 can be used in the pipe-type pipe fitting type by forming the pipe type.

The present invention having such a structure has the thickness of the upper and lower fastening ends 21, 22, 31 and 32 of the binding holes for binding the wheels formed at the outer diameters of the pipe joints at the respective ends of the sockets. The biconvex fastening fasteners 21a, 22a, 31a, and 32a are formed to be bisected so that the upper and lower portions thereof are opposite to each other. Left and right fastening holes 20 and 30 separated in semicircular shape when the pipes are separated by the pipes 30 and 30 are formed on the outer diameters of the joints 1 and 1a. Into the groove wheels 24 and 34 of the inner circumference to connect the bolt holes of the half-tight protrusions 21a, 22a, 31a, and 32a of the left and right fasteners into a circular body to match. The upper and lower protrusions of which the left and right sides coincide with each other so that the packing is closely attached to the rear connection portions 24 and 34 while being inserted into the packing 14 inserted into the insertion groove 13 of the inner circumference of the socket 10 as the joint portion of the pipe. Fastening end 21a, 22a, 31a, 32a By tightening the bolt of the bolt ball and ball socket each front end upper and lower fastening end (11), 21 volts, as the nut is to easily maintain the connection.
