Abstract

The present invention relates to a joint for a synthetic resin pipe. An objective of the present invention is to simply insert and compress a branch pipe (40) of a synthetic resin material which is easily plastically processed in a longitudinal direction with an escape prevention ring (20) of a metallic material and a sealing ring (30a, 30b) of a rubber material into a joint body (10) at once by one touch to structurally compress and seal the branch pipe (40) and then reliably seal and maintain the compressed and fixed portion while preventing the branch pipe (40) from retreating and escaping. An escape prevention ring (20) of a metallic material is depressed in the middle of a pipe insertion surface (12) of the joint body (10) before forming, and a sealing ring compression groove (16), on which a sealing ring (30a, 30b) of a rubber material is compressed and fixed, is formed along with a prevention ring compression groove (14) with an extended preventing ring compression protrusion (15). The escape prevention ring (20) has a plurality of escape prevention protrusions (22) cut out in a trapezoidal shape on the inside of an escape prevention body (24) to prevent a connection end (42) of the inserted and compressed branch pipe (40) from escaping after compression and fixation to tilt and protrude forward. Moreover, the sealing ring (30a, 30b) is formed on a sealing body (34) of a simple circular shape or an insertion guide end (32) is inclined and bent on the rear side of the sealing body (34). The branch pipe (40) of a synthetic resin material has a shape maintaining reinforcing part (44) of a metallic material depressed on the inside of the connection end (42) by a shape maintaining means.

Description

Joint for synthetic resin pipe

The present invention provides a simple one-touch insertion and compression of a synthetic resin branch pipe, which is a pipe for drinking water and boiler heating water, into the joint body.

It relates to a joint for a synthetic resin pipe that can be sealed and connected, and more specifically, a synthetic resin material that is easy to plastically process.

It is a simple one-touch operation with a metal separation prevention ring and a rubber sealing ring in the longitudinal direction of the connecting pipe to the body of the joint.

Synthesis that allows the branch pipe to be securely sealed and fixed without being structurally separated back after compression sealing by inserting and crimping

It relates to joints for resin piping.

That is, the conventional pipe joint has a very complicated structure of the joint body 110, as well as when connected to the pipe insertion surface 111 of the joint body.

After inserting the compression ring 122 in the state in which the kill branch pipe 130 is inserted, and fastening the cap nut 120 thereon, the joint body (1)

10) Another crimping jig in a state in which the intermediate tool fastening part 114 is fixed with a crimping tool (not shown) such as a spanner.

By rotating the cap nut 120 pre-fastened to the nut fastening part 115 of the fitting body using a sphere and screwing the cap nut (1)

20), the branch pipe 130 could be integrally coupled to the joint body 110 by the screw tightening force.

Accordingly, the present invention solves all the problems of the existing pipe joints used for sealing connections between pipes made of synthetic resin by screwing.

This was devised to solve the problem of complicated screw coupling between pipes and pipes that require airtight maintenance as fluid and gas pipelines.

It is possible to reduce the man-hours by enabling simple one-touch compression bonding without damage to components by one pressurization operation.

Not only can the manufacturing cost be reduced while still being manufactured, but also structurally, there is no separation after the branch pipe is compressed and sealed on the body of the joint.

The purpose is to provide a joint for synthetic resin piping that can be securely sealed and fixed.

According to the joint for synthetic resin piping according to the present invention described above, the pipe and the pipe requiring airtight maintenance as a fluid and gas pipeline

It is possible to simply press and combine the connection between the probes with one touch without damaging the components by one press operation instead of complicated screwing.

It is possible to reduce the man-hours and the manufacturing cost as well as the branch pipe in the joint body.

It is expected that the effect of being able to be securely sealed and fixed without structurally falling out after closing is provided.

It is a cross-sectional view showing the internal structure of the coupling state of the joint for synthetic resin pipe by

As shown in the drawing, between the branch pipe 30 and the external supply pipe, which is required to maintain airtightness as drinking water and boiler heating water pipelines (

(not shown in the drawing) is simply pressed without damage to components by one-touch pressing operation instead of complicated screwing.

The joint for a synthetic resin pipe of the present invention that can be combined is a synthetic resin material that is inserted and compressed into the joint body 10 made of a synthetic resin material.

As the vaginal branch pipe 40 is inserted and compressed into the fitting body 10 with one touch, the anti-separation ring 20 and airtight oil, which are means to prevent falling out

It is sealed and fixed together with the sealing ring 30a, which is the water stop end, so that the pipe insertion surface 12 of the fitting body 10 is not required without a separate fixing means such as a cap nut.

After the connection end 42 of the branch pipe 40 is fixed by one-touch compression, a coupling structure that does not fall out can be made.

is configured to

10: joint body 12: pipe insertion surface
14: prevention ring compression groove 15: prevention ring compression jaw
