Abstract

The utility model relates to a non-screw multi-purpose pipe joint, comprising upper and lower semicircle pipes 4 and 7, and bolt 11. The non-screw multi-purpose pipe joint is characterized in that semicircle bosses 3 and 8 which are pressed on the upper sides of radical sealing rings 2 and 5 are respectively arranged at the both ends of the upper and the lower semicircle pipes 4 and 7; two axial sealing gaskets 14 and 15 are arranged at the axial boundary surfaces of the upper and the lower semicircle pipes 4 and 7. The utility model has the advantages that screws do not need to be hinged on pipes which are connected when the pipes are connected; the non-screw multi-purpose pipe joint is convenient to install; the long dimensions of the pipes is conveniently adjusted. The non-screw multi-purpose pipe joint can be used as a pipe joint and a movable joint; the non-screw multi-purpose pipe joint can automatically eliminate the influence of the heat expansion and cold contraction of the pipes; the non-screw multi-purpose pipe joint is safe.

Description

Non-screw multi-purpose pipe joint

The utility model relates to a kind of pipe joint, particularly relates to a kind of screw-thread-free pipe joint.

The connection of at present industrial or domestic gas, liquid pipeline needs a large amount of pipe joints, and modal have a common straight connector, the head of pipe need be twisted into screw thread during use, is screwed on the pipe joint respectively then to get final product.This straight connector except the pipe head must being twisted into screw thread, is installed the restricted local inconvenience of using of occasion at some.Therefore also have a kind of union commonly used, this status of joint two-part can suitably be adjusted the pipe range size during installation, this union, though more easy to use than straight connector, screw thread also must strand be made in institute adapter road, need heavy support and strand pipe device, very inconvenient.Above-mentioned in addition joint bursts apart sometimes because of expanding with heat and contract with cold.

The purpose of this utility model is a kind of screw-thread-free pipe joint of design, replace used straight connector and union, do not need during adapter pipe strand system screw thread, easy for installation, be convenient to adjust the pipe range size, can restricted local use of occasion be installed at some, and can eliminate the influence of expanding with heat and contract with cold, safe and reliable.

The utility model is achieved in that how a kind of no screw thread comprises upper and lower half garden pipe with pipe joint, 4 engaging lugs of upper and lower position correspondence are each other respectively arranged on the upper and lower half garden pipe, respectively there are corresponding hole and bolt to be connected on the engaging lug, the place, two ends that it is characterized in that upper and lower half garden pipe has half garden boss to be pressed in above the radial direction seal ring respectively, and there are two axial gaskets at the axial separating surface place of upper and lower half garden pipe.

Following accompanying drawing has provided embodiment of the present utility model, is described further in conjunction with the accompanying drawings:

Symbolic representation on Fig. 1～Fig. 7 is as follows:

Connected tube 1, radial direction seal ring 2, half garden boss 3, first garden pipe 4, radial direction seal ring 5, connected tube 6, second garden pipe 7, half garden boss 8, engaging lug 9, hole 10, bolt 11, engaging lug 12, hole 13,

axial gasket

14,15, pressing groove 16.The transverse section of radial

direction seal ring

2,5 is " recessed " type, and pressing groove 16 is arranged on its outer surface, and semi-convex 3,8 of upper and lower half garden pipe 4,7 in pressing groove 16.The transverse section of

axial gasket

14,15 is a T-shape, and radial

direction seal ring

2,5 and

axial gasket

14,15 usefulness rubber are pressed into one.

The utility model is to use like this, radial

direction seal ring

2,5 will be put respectively above the connected

pipe

1,6, half garden boss 8 on the lower tube half 7 is placed in the pressing groove 16, then half garden boss 3 on first garden pipe 4 is placed in the pressing groove 16, and

axial gasket

14,15 is placed on the axial separating surface place of upper and lower half garden pipe respectively, this moment is fastening with upper and lower half garden pipe 4,7 with bolt 11, and connected

tube

1,6 is connected.

The utility model has the advantages that, do not need during adapter strand screw thread processed on the connected tube, easy for installation, be convenient to adjust the pipe range size. This no screw thread multipurpose joint can be used as pipe joint and articulation and uses, and can automatically eliminate the impact that pipeline expands with heat and contract with cold, and is safe and reliable.
