Description

Pipe connection socket

The present invention relates to a pipe connection socket for connecting a pair of pipes in close proximity, more specifically in the shape of a hollow body in which the pipe is inserted, the inner circumferential surface of both ends is formed with an inclined surface to reduce the diameter toward the inside, A housing having a thread formed on an outer circumferential surface thereof; A screw thread is formed on an inner circumferential surface of the screw so as to be coupled to threads formed at both ends of the housing, and a rear end of the screw thread includes a fastening nut having an inclined surface formed to decrease in diameter toward the rear; A packing having a hollow body into which a tube is inserted, and having an inclined surface corresponding to the inclined surface of the housing at one outer peripheral surface thereof; An arm ring having a hollow body into which a tube is inserted, and having an inclined surface corresponding to an inclined surface of the tightening nut on an outer circumferential surface of one end thereof; Washer coupled between the packing and the arm ring: consisting of a washer is screwed to the housing by rotating the tightening nut is pressed by the inclined surface of the housing and the inclined surface of the tightening nut and the inclined surface of the housing and the inclined surface of the arm ring, respectively. The diameter is reduced to the pipe connection socket characterized in that it is fixed to the outer peripheral surface of the pipe inserted into the hollow hole.

Pipe joints or pipe connection sockets are sockets for connecting a pair of pipes or pipes in close proximity and should be completely blocked to prevent the fluid moving into the pipe.

In the prior art of such a pipe connection socket, Patent Document No. 1996-0007436, a cylindrical body having both ends open to have a connection portion connected to the socket at one end; A socket in which one end is connected to the connecting portion of the main body, a pipe is inserted into the other end, and a taper portion having a reduced diameter in the outward direction is formed on an inner circumferential surface around the end where the pipe is inserted; An insert provided inside the main body so as to be able to move back and forth within a certain range; And a tube connector, characterized in that consisting of a collet which is fitted to allow the sliding movement between the inner peripheral surface and the insert of the socket.

In another prior art, in forming the pipe connector in Utility Model Publication No. 1993-0004986, a stepped groove and a fixing groove are formed on the inner surface of the pipe-shaped body to insert an O-ring, and the inclined surface extending outward at the end. Insert the C-type stop ring having the same inclined surface to form a, and when the nut is fastened by screwing the nut drilled with the male screw around the body to maintain a gap between the body and the body from the outside of the C-type stop ring Tube connector is characterized in that the C-type stop ring is configured to be forced to be fixed to the outside of the pipe while sliding.

However, in the above-mentioned prior art, even when a pair of adjacent pipes are connected, an accident in which the fluid flowing inward flows out often occurs.

The present invention has been made to solve the above-mentioned problems, and because the housing, the packing and the tightening nut and the arm ring are in contact with each other by the inclined surface to provide a pipe connection socket which is excellent in adhesion and can prevent the leakage of fluid. There is a purpose.

The pipe connecting socket of the present invention has a hollow body into which a tube is inserted, and an inner circumferential surface of both ends is formed with an inclined surface such that its diameter decreases toward the inside thereof, and a housing having a thread formed on the outer circumferential surface thereof; A screw thread is formed on an inner circumferential surface of the screw so as to be coupled to threads formed at both ends of the housing, and a rear end of the screw thread includes a fastening nut having an inclined surface formed to decrease in diameter toward the rear; A packing having a hollow body into which a tube is inserted, and having an inclined surface corresponding to the inclined surface of the housing at one outer peripheral surface thereof; An arm ring having a hollow body into which a tube is inserted, and having an inclined surface corresponding to an inclined surface of the tightening nut on an outer circumferential surface of one end thereof; Washer coupled between the packing and the arm ring: consisting of a washer is screwed to the housing by rotating the tightening nut is pressed by the inclined surface of the housing and the inclined surface of the tightening nut and the inclined surface of the housing and the inclined surface of the arm ring, respectively. As the diameter is reduced, the outer peripheral surface of the pipe inserted into the hollow hole is firmly fixed.

The pipe connection socket of the present invention has an excellent tightening force by screwing the housing and the fastening nut, and the housing, the packing, and the fastening nut and the arm ring are in contact with each other by the inclined surface, so that the adhesive force is excellent and the outflow of the fluid is prevented. There is.
