Abstract

The utility model relates to a crimp three-way joint. A ring shape bayonet catch is arranged on the inserting end of the joint. A ring shape inwards concave groove is arranged near the inserting end of the joint; a seal ring is arranged in the groove. The utility model provides a crimp three-way joint, which is a crimp structure that extends into the main pipe to accomplish connecting and fixing. Thus rapid assembling is realized and good sealing effect is guaranteed.

Description

The pressure-connected type tee union

Technical field

The utility model relates to a kind of novel pressure-connected type tee union, specifically in order to realize that threeway connects the joint structure design of various pipes.

Background technique

In the various pipes process of deployment,, particularly need when setting up link, the pipeline intermediate portion normally need to be connected with tee union at present because pipe-line changes or additional temporarily other pipelines.

Existing tee union often needs original pipeline to block, by tee union the both sides pipeline is coupled together.It is bigger that the internal structure of this Placement and tee union connects change to original pipeline, often needs to solve especially sealing problem.

Need flow charts such as spot welding when blocking pipeline, operational sequence complexity, IWS International Workman Standard are had relatively high expectations.

And, be not easy to more implement above-mentioned execute-in-place when comparatively intensive or surrounding environment space is comparatively narrow when pipe laying, require follow-up additional sealing configuration and operation to require also higher.

Existing tee union obviously can't address the above problem simultaneously.

Summary of the invention

Pressure-connected type tee union described in the utility model is intended to address the above problem and not enough, provide a kind of stretch into be responsible in and finish the pressure-connected type structure that is connected and fixed, thereby realize a kind of quick mounting and guarantee the threeway Placement of sealing effect.

Pressure-connected type tee union described in the utility model is provided with an annular buckle in its insertion end, and the front end side of buckle is about " L " shape.

Closing on the groove that joint insertion end position is provided with an annular indent, a seal ring is set in groove.

When erection joint, in groove, be inserted in earlier seal ring, buckle is stretched into from being responsible for opening, then buckle outwards is squeezed to be fastened on from the inboard and is responsible on the tube wall, thereby joint is fastened on the person in charge's opening.Joint can connect another pipeline by internal thread after being connected to and being responsible for upward, thereby realizes threeway.

Above-mentioned pressure-connected type tee union has the following advantages and effect:

1, joint is realized tight the connection with the person in charge, has the better seal effect;

2, need not complex job during jointing, operational sequence is simple, IWS International Workman Standard requires lower;

Lower, easy to implement when 3, installing for pipe laying present situation and surrounding environment spatial requirement.

Description of drawings

Fig. 1 is the cut-away section schematic representation of pressure-connected type tee union before unfixing;

Fig. 2 is the schematic representation of pressure-connected type tee union after fixing;

Fig. 3 is the lateral parts generalized section of Fig. 2;

Wherein, include tee union 1, be responsible for 2.

Tee union 1 has groove 11, seal ring 12, buckle 13, internal thread 14.

Embodiment

Embodiment 1, and pressure-connected type tee union 1 described in the utility model needs to use drilling tool leave a hole from being responsible for 2 outsides before connecting the person in charge 2, requires the shape in hole and the insertion end of size and joint 1 to adapt.

Be provided with the buckle 13 of an annular in the insertion end of joint 1, from the section of Fig. 1 to Fig. 3 partly, the front end side of buckle 13 is similarly " L " shape.

Be provided with the groove 11 of an annular indent in the insertion end of closing on joint 1, wherein be provided with a seal ring 12.

When erection joint 1, in groove 11, be inserted in earlier seal ring 12, and buckle 13 is stretched into from the opening of being responsible for 2 quilt and leaving; Then, use special tool that the buckle 13 of joint 1 is outwards pushed from the inboard; Utilize " L " shape front end of buckle 13 to be fastened on the person in charge 2 the tube wall, thereby joint 1 is fastened on the person in charge 2 opening.

Joint 1 has internal thread 14, after joint 1 is connected on the person in charge 2, can connect another pipeline by the mode of being spirally connected, thereby threeway connects.

Seal ring 12 by joint 1 and buckle 13 are finished jointly and are responsible for 2 be connected, and play the effect of sealing simultaneously.

Claims

1, a kind of pressure-connected type tee union, it is characterized in that: the insertion end of joint is provided with the buckle of an annular, and the front end side of buckle is about " L " shape.

2, pressure-connected type tee union according to claim 1 is characterized in that: be provided with the groove of an annular indent in the insertion end of closing on joint, wherein be provided with a seal ring.
