CN200940750Y - Larg caliber ribbed pipe spigot-and-socket mouth - Google Patents

Abstract

The utility model relates to a pipe spigot joint in specific to a large diameter reinforcement pipe spigot joint comprising a front connection joint, a medium connection face and an inclined connection joint which is connected with the flaring end of the reinforcement pipe. The spigot joint has an integration body and a long strip reinforcement is arranged on the external surface of the spigot joint. A saw shaped reinforcement which does not add the amount of the materials is arranged on the external surface of the medium connection face. The technology effects lie in that the amount of the materials which is originally used for the long strip reinforcement are divided into two parts. One part thereof is used to form the saw shaped reinforcement on the external surface of the medium connection face. The other part thereof is used to thicken the wall thickness of the spigot joint. In this way, the strength of the spigot joint can be greatly reinforced thus avoiding the problems of deformation, rupture and leakage because of the strength insufficiency of the spigot joint.

Description

Heavy caliber riffled tube joint socket

Technical field

The utility model relates to a kind of pipeline joint socket, in particular, relates to a kind of joint socket of heavy caliber riffled tube.

Background technique

In the prior art, the heavy caliber riffled tube is after extruding and moulding, pipe after the moulding is heated, softens, carry out enlarging then and make it to form the pipeline joint socket, as shown in Figure 1 and Figure 2, joint socket is by preceding connection mouth 1, middle junction surface 2 and be connected in the inclined-plane connection mouth 3 at the flared end place of riffled tube 4, and joint socket is one-body molded, and outer surface is provided with rectangular muscle 6.General pipe connecting method is the joint socket that the tail end of connecting tube 4 is inserted another root connecting tube 41, comes closed conduit by rubber band 7 is installed between the joint socket of connecting tube 4 and connecting tube 41.Owing to extended at joint socket position pipe, make the pipe wall thickness reduction at original enlarging position, the attenuate amount is about 20%, so just causes pipeline joint socket position greatly to descend than the intensity at other position of pipeline.Reflect generally that in the market the common the poorest place of riffled tube intensity is exactly the joint socket position, this pipeline position is in transportation, yielding and break in the construction and installation process, thereby leaks.

The model utility content

The purpose of this utility model is: provide a kind of can be because of enlarging intensity weaken the joint socket of the heavy caliber riffled tube that does not also increase the materials amount simultaneously and make the mfg. moulding die of this kind joint socket.

In order to solve the problems of the technologies described above, the utility model provides following technical proposals:

A kind of heavy caliber riffled tube joint socket, comprise preceding connection mouth, middle junction surface and be connected in the inclined-plane connection mouth at the flared end place of riffled tube, described joint socket is one-body molded, outer surface is provided with rectangular muscle, materials amount in the described joint socket unit length equals the materials amount of riffled tube in the unit length, and the outer surface of described middle junction surface is provided with continuous saw shape muscle.

The connection mouth wall thickness is even before described, and middle junction surface wall thickness is even, and inclined-plane connection mouth wall thickness is even.

The manufacturing module of making above-mentioned heavy caliber riffled tube joint socket is provided with a through hole, the indent indentation of saw shape muscle form fit on the outer surface that is provided with on the inwall of through hole with joint socket.

Technique effect of the present utility model is: the materials amount that will be used for rectangular muscle originally is divided into two-part: the saw shape muscle of the outer surface of junction surface in the middle of a part is used to form (significantly reducing because of the materials amount of the materials amount of sawing the shape muscle with respect to rectangular muscle); A part is used to thicken the joint socket wall thickness, and makes the wall thickness of three parts of joint socket even.So just can strengthen the intensity of joint socket greatly, thereby avoid the problem that joint socket is out of shape, breaks, leaks owing to insufficient strength in the actual use.

Description of drawings

Fig. 1 is for being provided with the schematic representation of the joint socket of rectangular muscle in the prior art.

Fig. 2 inserts another pipeline joint socket schematic representation in the prior art with connecting tube.

Fig. 3 is the schematic representation of the utility model joint socket.

Fig. 4 is for making the module diagram of the utility model joint socket.

Embodiment

Explanation and embodiment are described further the utility model with reference to the accompanying drawings:

As shown in Figure 3, the outer surface of the middle junction surface 2 of joint socket is provided with saw shape muscle 5, saw shape muscle 5 dense arrangement, and radial length greatly reduces with respect to rectangular muscle 6, this materials amount that just is equivalent to be used to form rectangular muscle 6 originally is divided into two-part, and a part is used to form saw shape muscle 5, and a part is used to form the wall thickness of joint socket, so both can strengthen the intensity of joint socket by saw shape muscle 5 is set, joint socket is not also because enlarging and wall thickness reduction reduces intensity simultaneously.

As shown in Figure 4, the manufacturing module of making the utility model joint socket is provided with a through hole identical with joint socket length, the indent indentation 8 of saw shape muscle 5 form fit on the outer surface that is provided with on the inwall of through hole with joint socket, simultaneously, it is corresponding identical with the preceding connection mouth 1 of joint socket, inclined-plane connection mouth 3 shapes that joint socket is made other positions of module through-hole wall, like this, after the riffled tube flared end being put into the manufacturing module, carry out forming the joint socket that comprises preceding connection mouth 1, middle junction surface 2 and inclined-plane connection mouth 3 described in the utility model after the abundant compression flare.

Claims (3)

1, a kind of heavy caliber riffled tube joint socket, comprise preceding connection mouth (1), middle junction surface (2) and be connected in the inclined-plane connection mouth (3) at the flared end place of riffled tube (4), described joint socket is one-body molded, outer surface is provided with rectangular muscle (6), materials amount in the described joint socket unit length equals the materials amount of riffled tube (4) in the unit length, it is characterized in that: the outer surface of junction surface (2) is provided with continuous saw shape muscle (5) in the middle of described.

2, heavy caliber riffled tube joint socket according to claim 1 is characterized in that: connection mouth (1) wall thickness is even before described, and middle junction surface (2) wall thickness is even, and inclined-plane connection mouth (3) wall thickness is even.

3, make the manufacturing module of claim 1 or 2 described heavy caliber riffled tube joint socket, it is characterized in that: described module is provided with a through hole, be provided with on the inwall of through hole can with the indent indentation (8) of saw shape muscle (5) form fit on the outer surface of joint socket.
