Technical Field

The utility model relates to a pipe fitting, in particular to a novel socket pressing type pipe fitting for quickly curing anaerobic adhesive.

Background

Socket joint pressfitting formula pipe fitting is a novel pipe fitting, including a socket joint pressfitting soldered connection, socket joint pressfitting soldered connection is bilayer structure, the one end welding is in the same place, one end is uncovered, then add the anaerobism glue in socket joint pressfitting soldered connection inside, insert tubular product wherein again, the one end of tubular product will be arranged in the anaerobism glue, adopt dedicated pressfitting instrument again with tubular product and socket joint pressfitting soldered connection pressfitting together, because after the pressfitting, the anaerobism is glued and is sealed between disconnected and pressfitting department in the welding, isolated with the air, sealed glue in seal space solidifies sealedly under the oxygen deficiency state, thereby strengthen the fastness of product. However, the following disadvantages still exist in this way:

(1) aiming at the socket pressing type pipe fittings of DN200 and above types, anaerobic adhesive is used for the product in the pressing process and easily overflows from the inner wall of the pipe fitting, the adhesive consumption is large, and the waste is serious.

(2) After the pipe and the pipe are in compression joint, the pipe and the pipe are not well attached, air is easy to carry out, and the anaerobic adhesive can not be cured within a short time; when the early engineering is accepted; the pressure is unstable during the water pressure test, and the leakage is easy.

Disclosure of Invention

The utility model aims to solve the problems, and provides a novel socket pressing type pipe fitting which can avoid the overflow of anaerobic adhesive in the pressing process, has high curing speed and good sealing effect and can quickly cure the anaerobic adhesive.

In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a novel socket press-fit pipe fitting for quickly curing anaerobic adhesive comprises a socket press-fit welding head, wherein the socket press-fit welding head comprises an inner pipe body and an outer pipe body which are arranged in a nested manner, the bottoms of the socket press-fit welding head and the outer pipe body are welded together to form a welding end, the top of the socket press-fit welding head is an open end for inserting a pipe, an anti-overflow part is arranged at the middle lower part of the socket press-fit welding head, the anti-overflow part is a pair of first annular grooves which are arranged oppositely, the two first annular grooves are respectively positioned on the inner walls of the inner pipe body and the outer pipe body, and the circle centers of the first annular grooves are opposite;

a second annular groove is formed in the inner wall of the inner pipe body above the anti-overflow part, and a matched sealing ring is arranged in the second annular groove;

the first annular groove and the second annular groove are coaxially arranged with the socket press welding joint.

Preferably, the method comprises the following steps: the socket press welding joint is made of stainless steel materials.

Compared with the prior art, the utility model has the advantages that: the space below the anti-overflow portion is used for injecting anaerobic adhesive, the anti-overflow portion is a pair of first annular grooves which are oppositely arranged, the space distance between the two first annular grooves is larger than the distance between the inner pipe body and the outer pipe body, when the adhesive liquid is excessively injected, the adhesive liquid can overflow into the space formed by the two first annular grooves in the pressing process, and the overflow is avoided. And after the pipe fitting is pressed, the sealing ring deforms under the action of the pipe and the pipe fitting, so that the anaerobic adhesive below is completely isolated from air, and the anaerobic adhesive can be cured within 72 hours.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the present invention in use when connecting pipes.

In the figure: 1. an outer tubular body; 2. an inner tube body; 3. a first annular groove; 4. a seal ring; 5. a pipe; 6. and (5) anaerobic adhesive.

Detailed Description

The utility model will be further explained with reference to the drawings.

Example 1: referring to fig. 1 and 2, a novel socket press-fit pipe fitting for rapid curing of anaerobic adhesive comprises a socket press-fit welding head, wherein the socket press-fit welding head comprises an inner pipe body 2 and an outer pipe body 1 which are nested with each other, the bottoms of the socket press-fit welding head and the outer pipe body are welded together to form a welding end, the top of the socket press-fit welding head is an open end into which a pipe 5 is inserted, an anti-overflow part is arranged at the middle lower part of the socket press-fit welding head, the anti-overflow part is a pair of first annular grooves 3 which are oppositely arranged, the two first annular grooves 3 are respectively positioned on the inner walls of the inner pipe body 2 and the outer pipe body 1, and the centers of circles are opposite;

a second annular groove is formed in the inner wall of the inner pipe body 2 above the anti-overflow part, and a matched sealing ring 4 is arranged in the second annular groove;

the first annular groove 3 and the second annular groove are coaxially arranged with the socket press welding joint.

The socket press welding joint is made of stainless steel materials.

The using method of the utility model comprises the following steps:

(1) earlier through special instrument of gluing, pour into socket joint press fit welding head with anaerobic adhesive 6, in the space of anti-overflow portion below, because the space of anti-overflow portion is great, can not require the amount of anaerobic adhesive 6 too accurate, can simplify the operation flow, improve injecting glue efficiency.

(2) Inserting a matched pipe 5, wherein one end of the pipe 5 is immersed into the anaerobic adhesive 6;

(3) the present invention and the pipe 5 are pressed together by a pressing tool such as a ring press, a clinch press. During the pressfitting, the excessive glue when tubular product 5 and pipe fitting extrusion deformation can get into the anti-overflow portion, can not upwards remove again, can not overflow to sealing ring 4 department. And the sealing ring 4 is also deformed to seal, so that the anaerobic adhesive 6 is completely isolated from air, and the anaerobic adhesive 6 is rapidly solidified.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
