Abstract

A coupling for connecting pipes is provided to connect pipes easily, and to seal a joint portion of the pipes completely by assembling a female screw of an inverse L-shaped race with a horizontal male screw of a pipe assembling unit. An inverse L-shaped race(10a) is formed by expanding an end of a socket(10), and a horizontal female screw(12) is formed in an inner periphery of the inverse L-shaped race. A circular packing(1) is inserted to an end of a pipe(20) to be connected, and a vertical protruded frame(21) is inserted to the inverse L-shaped race. A pipe assembling unit(30) is inserted to the inner periphery of the inverse L-shape race. A horizontal male screw(31) is formed in outer periphery of the pipe assembling unit, and contacted to the vertical protruded frame. An outer periphery(20a) of the pipe is inserted to the inner periphery of the socket, and the horizontal male screw is combined with the horizontal female screw. The pipes are connected by contacting the vertical protruded frame to the circular packing.

Description

{A coupling for piping connection}

The present invention relates to a pipe joint type coupling that prevents leakage by simplifying the connection of the pipe and ensuring a tight seal.

In conventional pipe joint couplings, a tapered female thread is formed at the inner circumference of the socket end to form a tapered male screw that matches the tapered female thread at the distal end of the pipe to be connected to it. When the thread was wound and threaded to the tapered female thread at the socket end, it was necessary to tighten it with all its force as a wrench to prevent leakage.

In the present invention to improve such a problem is formed by expanding the tip of the socket The inner circumferential surface between the inner end and the inner end of the round yoke wheel has a spaced inner peripheral surface to form a horizontal female screw, and the outer end surface of the pipe which is inserted into the inner circumference of the socket can be inserted at the end of the pipe. Form a vertical projecting frame of height that can be inserted into the inside of the urine wheel, and round packing on the front end of the vertical projecting frame and to the rear Insert the pipe fasteners that can be inserted into the inner circumference of the rim, so that the ends of the outer circumferential horizontal male threads are in contact with the vertical protruding frame. As a sphere When the rear flange is connected to the inner peripheral horizontal female screw of the type urinal wheel as the outer peripheral horizontal male screw, the round flange inside the vertical protrusion is in close contact and sealed. Same as

Each tip of the socket 10 is enlarged and formed A circular packing is formed at the distal end of the pipe 20 to form and connect a horizontal female screw 12 with an inner circumferential surface 11 interposed therebetween at an inner end of the inner urging wheel 10a at the inner end thereof. 1) by inserting the outer peripheral surface (20a) between the gap that can be inserted into the inner circumference of the socket (10) A vertical projecting frame 21 having a height that can be inserted into the mold yaw ring 10a is formed, and a circular packing 1 is formed at the end of the pipe 20 around the vertical projecting frame 21, and the pipe 20 is formed. In the rear Insert the pipe fasteners 30, which can be fitted into the inner circumference of the type yaw ring 10a, so that the ends of the outer peripheral horizontal male threads 31 are in contact with the vertical protruding frame 21, respectively, Insert the outer peripheral surface 20a of the space | interval into the inner periphery of the front-end | tip of the socket 10, and as a piping fastening hole 30 The rear flange 32 is fastened to the inner peripheral horizontal female thread 12 of the inner yaw ring 10a as the outer peripheral horizontal male thread 31 so that the circular packing 1 is in close contact with the vertical protrusion frame 21. In the assembly, the support washer 2 may be inserted between the circular packing 1 and the vertical protruding frame 21 inserted into the front end of the pipe 20 to support the inner circular packing 1 accurately at the outer surface. .

And the overall shape of the socket 10 can be used as the elbow type pipe connection state can be used as elbow type pipe joint type and the overall shape of the socket 10 can be used as the tee type pipe joint type can be used. In addition, the connection of the reducer pipe and various valves can be easily connected to the pipe by using the joint coupling of the present invention.

When explaining the assembled state of the present invention having such a configuration, the circular packing (1) to the vertical projection frame 21 toward the front end of the vertical projection frame 21 protruding to the front end of the pipe 20 to be connected to the vertical projection frame (21) The front end of the outer peripheral horizontal male screw 31 of the pipe fastening hole 30 to be in contact with the vertical protruding frame (21), and then the outer peripheral surface (20a) of the gap between the end of the pipe (20) to the socket ( 10) Insert into the inner periphery of the tip and as the pipe fastener 30 The rear flange 32 of the pipe fastening hole 30 is fastened to the inner peripheral horizontal female screw 12 of the type yaw ring 10a by an external peripheral horizontal male screw 31. When fastened so as to be in close contact with the front end of the mold-expanded ring (10a), the vertical protrusion frame 21 of the pipe 20 is to close the inner circular packing (1) The connection between the pipes is fixed in a state in which the pipes connected to the inner circumference of the socket are completely sealed by being in close contact with the inner circumferential surface 11 between the inner circumferential ends of the mold yaw ring 10a.

And when assembling the pipe fastener (30) by connecting the pipe to the socket end Since the inner circumferential female thread of the inner ring and the outer circumferential male thread of the pipe fastener are formed with horizontal threads, it can be easily tightened by hand without having to use the wrench to apply the full force by winding the thread around the tapered thread like a conventional socket It is.
