Abstract

The present invention inserts the ends of the joints of both pipes to be connected so that both ends abut against both ends of the packing fitted in the inner circumferential insert grooves of the socket middle part to seal the joints of the pipe and the middle part of the upper and lower hard rings. It is the end hanger of the connecting rod attached to the outside, and it is inserted into the recess formed at the distal end of the socket so as to correspond to this, and then the left and right fastening ends of the upper and lower hard rings are fastened as bolts and nuts, and the joints of both pipes Couplings for pipe joints, to secure the socket to both sides of the socket.

Description

Coupling for pipe joints {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 separated by the upper and lower semicircles of the joints of both pipes are assembled as bolts and nuts, which is difficult to assemble due to the 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, the ends of the joints of both pipes to be connected are inserted so that both ends abut against both ends of the packing fitted in the inner peripheral edge insertion grooves of the socket middle part, and the pipe joints are sealed. It is the end hanger of the connecting rod attached to the outer side of the middle part of the upper and lower hard rings. It is inserted into the recess formed at the ends of the socket so as to correspond to this, and the left and right fastening ends of the upper and lower hard rings are bolted and nuts. As described in detail according to the drawings to fasten the joint portion of both pipes firmly to both sides of the socket as follows.

The ends of the joints of both the pipes 1 and 1a, which are to be connected to both ends of the well-known socket 10 in which the packing 12 is fitted into the inner peripheral both insertion grooves 11 of the middle of the socket, are in the middle of the socket 10. Inserts 21 and 21a which are inserted into both ends of the packing 12 of the inner circumferential edge insertion groove 11 of the part so as to be in contact with each other and attached to one side of the middle part of the upper and lower hard rings 20 and 20a. And the left and right fastening rings of the upper and lower hard rings after being inserted into the recesses 13 and 13a formed at the distal end portions 22 and 22a of the socket 10 and correspondingly formed at the distal ends of the socket 10. The ends 23 and 23a are fastened by bolts and nuts, and the ends of the hooks 22 and 22a of the connecting rods 21 and 21a are formed in a or b shape. The recesses 13 and 13a of the tip portions of the sockets can also be formed into a | or a shape so that they can be inserted so as to be caught by each other.

Serrated protrusion (a) can be formed on the edge of the contact inner surface of the upper and lower hard rings, or serrated protrusion (a) can be formed on the entire contact inner surface. Grooves (b) and protrusions (c) which are opposite to each other in the outer diameter of the puddle are formed so as to be engaged with irregularities so that the joints can be firmly fixed.

And it is possible to use the pipe connection state as a type pipe joint type by forming the socket shape as a type, and to use the pipe connection state as a type pipe fitting type by forming the socket shape as a type of pipe type.

When explaining the assembly state of the present invention having such a structure is inserted into the both ends of the socket (10) to the end of the joint portion of the two pipes (1), (1a) to be connected to the inner peripheral both insertion grooves 11 of the middle portion Both ends of the fitted packing 12 are inserted so that both ends abut each other to seal the joint portions of both pipes, and the connecting rods 21 and 21a attached to the outer side of the middle part of the upper and lower hard rings 20 and 20a. The hooks 22 and 22a of the sockets are inserted into the recesses 13 and 13a formed correspondingly to the tip portions of both sockets 10 and the sockets of the upper and lower hard rings as the tip hooks. After fastening to the upper and lower hard rings 20 and 20a, the left and right fastening ends 23 and 23a of the upper and lower hard rings 20 and 20a can be fastened with bolts and nuts to secure the joints of both pipes to both sides of the socket. There is.
