Abstract

The utility model discloses a spherical four-way pipe fitting. According to the technical scheme, the spherical four-way pipe fitting is characterized by comprising a spherical middle portion and four connection portions connected with the spherical middle portion integrally, wherein the other ends, corresponding to the spherical middle portion, of the four connection portions are respectively provided with a connection mouth which is of a wedge-shaped structure, and each wedge-shaped structure is gradually reduced from the corresponding connection mouth to the spherical middle portion. The connection mouths are of the wedge-shaped structures so that pipes in different specifications can be tightly connected with different portions of the connection mouths, and pipes in various specifications can be connected with the spherical four-way pipe fitting in a thermal energy welding or electric welding mode.

Description

Spherical four-way pipe fitting
Technical field
The utility model relates to a kind of pipe fitting, and more particularly, it relates to a kind of spherical four-way pipe fitting.
Background technique
Pipe fitting is tubing to be connected into the part of pipeline, and the multiplex material identical with tubing made.There are elbow (ell), flange, tee pipe fitting, four-way pipe fitting (crosshead) and reducing fittings (CONCENTRIC REDUCER) etc.Bend pipe is for the place of pipeline turning, and flange is used for making tubing and the interconnective part of tubing, connects and pipe end, and tee pipe fitting is for three places that tubing collects; Four-way pipe fitting is for four places that tubing collects; Reducing fittings is for two places that tubing is connected of different tube diameters.
At present, because the place that tubing is applicable is extensive, cause the tubing specification on market varied, in order to connect the tubing of all size, the specification of corresponding pipe fitting is also with regard to corresponding increase.A pipe fitting for the corresponding a kind of specification of tubing like this, causes the waste of material.
In addition, pipe fitting, in the process of moulding, can not guarantee it must is round structure, tubing was difficult in concentric with being connected of pipe fitting, when liquid flows in pipe fitting, and tubing and pipe fitting joint meeting discontinuity, cause tubing and pipe fitting joint insecure, cause leakage.Therefore, if tubing and pipe fitting when being connected not in concentric, also can reduce the working life of whole pipe-line system.
Model utility content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of can heat energy welding or the spherical four-way pipe fitting of the tubing of electric fusion welding all size.
For achieving the above object, the utility model provides following technological scheme: a kind of spherical four-way pipe fitting, comprise spherical intermediate portion and four joints that are wholely set with spherical intermediate portion, the other end of four corresponding spherical intermediate portions of joint all forms birdsmouth, described birdsmouth place is wedge-shaped structure setting, and wedge-shaped structure reduces gradually for being opening along birdsmouth place to spherical intermediate portion direction.
By adopting technique scheme, birdsmouth is arranged to wedge-shaped structure, the tubing of different size can be realized closely and connecting in the different parts of birdsmouth, thus a pipe fitting, can heat energy welding or the tubing of electric fusion welding all size.
The utility model is further set to: the birdsmouth place of described four joints is all wedge-shaped structure setting.
By adopting technique scheme, each birdsmouth of a pipe fitting can connect the tubing of all size.
The utility model is further set to: the inwall at described birdsmouth place is provided with groove.
By adopting technique scheme, can on the tubing that need to peg graft with pipe fitting, tubing elastic bumps be set, make tubing elastic bumps and groove suitable, thereby guarantee that pipe fitting and tubing are in concentric position, make the joint of pipe fitting and tubing stressed evenly, extend the working life of whole pipe-line system.
The utility model is further set to: the outer wall at described birdsmouth place is provided with elastic bumps, and described groove is corresponding with elastic bumps.
By adopting technique scheme, can on the tubing that need to peg graft with pipe fitting, tubing groove be set, make elastic bumps and tubing groove suitable, thereby guarantee that pipe fitting and tubing are in concentric position, make the joint of pipe fitting and tubing stressed evenly, extend the working life of whole pipe-line system.
Accompanying drawing explanation
Fig. 1 is the spherical four-way pipe fitting embodiment's of the utility model structural representation.
Embodiment
With reference to Fig. 1, the spherical four-way pipe fitting embodiment of the utility model is described further.
A kind of spherical four-way pipe fitting, comprise spherical intermediate portion 1 and four joints 2 that are wholely set with spherical intermediate portion 1, the other end of four corresponding spherical intermediate portions 1 of joint 2 all forms birdsmouth 21, described birdsmouth 21 places are wedge-shaped structure setting, and wedge-shaped structure reduces gradually for being opening along birdsmouth 21 places to spherical intermediate portion 1 direction.
By adopting technique scheme, birdsmouth 21 is arranged to wedge-shaped structure, the tubing of different size can be realized closely and connecting in the different parts of birdsmouth 21, thus a pipe fitting, can heat energy welding or the tubing of electric fusion welding all size.
Birdsmouth 21 places of described four joints 2 are all wedge-shaped structure setting.
By adopting technique scheme, each birdsmouth 21 of a pipe fitting can connect the tubing of all size.
The inwall at described birdsmouth 21 places is provided with groove 22.
By adopting technique scheme, can on the tubing that need to peg graft with pipe fitting, tubing elastic bumps be set, make tubing elastic bumps and groove 22 suitable, thereby guarantee that pipe fitting and tubing are in concentric position, make the joint of pipe fitting and tubing stressed evenly, extend the working life of whole pipe-line system.
The outer wall at described birdsmouth 21 places is provided with elastic bumps 23, and described groove 22 and elastic bumps 23 are corresponding.
By adopting technique scheme, can on the tubing that need to peg graft with pipe fitting, tubing groove be set, make elastic bumps 23 and tubing groove suitable, thereby guarantee that pipe fitting and tubing are in concentric position, make the joint of pipe fitting and tubing stressed evenly, extend the working life of whole pipe-line system.
