Description

A kind of pipe joint that improves efficiency of assembling and reliability

Technical field

The present invention relates to a kind of pipe joint that improves efficiency of assembling and reliability.

Background technique

In the existing technology, PVC, PVC-U and PE manage in industry and civil building and are widely used in the pipeline of city, especially in plumbing, are widely used.In view of the profile of body itself be circular, the pipe joint that uses that matches with it has interior circular port, and again through welding enforcement connection, pipe joint can be implemented can also to implement outside the connection between the body and being connected of parts such as tap in the body insertion tube joint.Pipe joint has butt joint reducing, butt joint reducing or equal tee, butt joint plug, butt joint elbow and the inside and outside tooth elbow of socket joint etc.The outer wall of joint be generally cylindrical or pass through mutually cylindrical; Like this; When pipe joint and body or corresponding part assembling, need fix pipe joint usually, and because the circular outer wall of pipe joint is difficult to use corresponding tool to be fixed; Whether installation procedure puts in place with regard to very consuming time and installation and is difficult to confirm like this, has a strong impact on the q&r of assembling.

Summary of the invention

The purpose of this invention is to provide a kind of pipe joint that improves efficiency of assembling and reliability; The circular outer wall of pipe joint is difficult to use corresponding tool to be fixed in the existing technology to overcome; Whether installation procedure is very consuming time and install to put in place and be difficult to confirm, has a strong impact on the deficiency of the q&r of assembling.

The objective of the invention is to realize through following technological scheme:

A kind of pipe joint that improves efficiency of assembling and reliability comprises joint, and the outer wall of said joint is provided with first plane, and first plane parallel is in the axle center of body; There are two pairs first planes and second plane in the plane that is parallel to each other, and the transition circle cambered surface is arranged between the adjacent plane, and the distance between the plane that is parallel to each other is more than or equal to the diameter of transition cambered surface between the adjacent plane; The plane that is parallel to each other is that two pairs and adjacent plane first plane and second plane are perpendicular to one another, the equal diameters of the transition cambered surface between the adjacent plane, and the distance between the plane that is parallel to each other equals the diameter of transition cambered surface; Said joint is embedded with thread bush.

Beneficial effect of the present invention is: in the assembly process; Can be with back-up wrench or claim the plane that is parallel to each other on the pipe joint that instruments such as stiff hand secure the above; So just can insert pipe fitting easily or turn parts such as tap; Can improve installation efficiency effectively, also guarantee the reliability of assembling simultaneously, thus the quality and the working life of having improved equipment.

Embodiment

Shown in Fig. 1-6; The described a kind of pipe joint that improves efficiency of assembling and reliability of the embodiment of the invention comprises joint 1, and the outer wall of said joint 1 is provided with first plane 2 that is parallel to each other; First plane 2 is parallel to the axle center of body; Can block first plane 2 that is parallel to each other easily with solid wrench or adjustable spanner, solid wrench or screw wrench cooperate and will rotate arbitrarily around the axle center by no-go nipple with first plane 2, rotate the connection that other pipe fittings or parts can be realized pipeline again; The plane that is parallel to each other has two pairs, and there is transition circle cambered surface 4 on first plane 2 and second plane 3 between the adjacent plane, and the distance between the plane that is parallel to each other is more than or equal to the diameter of transition cambered surface 4 between the adjacent plane; The plane that is parallel to each other is that two pairs and adjacent plane first plane 2 and second plane 3 are perpendicular to one another; The equal diameters of the transition cambered surface 4 between the adjacent plane; Distance between the plane that is parallel to each other equals the diameter of transition cambered surface 4; Guaranteeing to form the plane that is parallel to each other under the prerequisite of pipe thickness like this, not only practicing thrift material but also guaranteed the raising of efficiency of assembling.

Elbow structure among Fig. 1,2 is used for connecting isometrical body, makes body become vertical configuration to arrange, the position, both sides of joint is provided with first plane 2 that is parallel to each other, and first plane 2 among Fig. 1 is in the middle part, and in Fig. 2, first plane 2 is positioned at both sides; Another is in the excurvation and the interior crook of elbow respectively to second plane 3 that is parallel to each other, and the first adjacent plane 2 is perpendicular to one another with second plane 3, and like Fig. 2, first plane 2 and second plane 3 can extend to the other port along an end port of elbow.Second plane 3 at outer tube place can be with the transition of postponing of cambered surface and two ends at the position, stage casing, and in Fig. 1, inboard turn of bilge position then can adopt two second planes 3 that are perpendicular to one another directly to intersect transition.

Fig. 3,4 is the structure of reducing coupling, and at the minor diameter tip side, the plane that is parallel to each other is set has two pairs first planes 2 and second plane 3, and transition cambered surface 4 is arranged between the two; At the major diameter tip side, the plane that is parallel to each other is set has two pairs the 3rd planes 5 and Siping City's face 6, and transition cambered surface 4 is arranged between the two, between the section of large and small diameter street corner, the conical surface 7 transition is arranged.
