Abstract

The utility model discloses a three-way connector belonging to the technical field of pipeline connection, which is composed of a three-way body. The utility model is characterized in that The inner walls of the three connecting openings of the three-way body are provided with sealing slots and locking slots and N (N is not smaller than 2) axial slots communicated with the locking slots. The utility model has simple structure and is connected with a pipe to be connected with convenient disassembly and good sealing effect. The work efficiency can be increased.

Description

The threeway joiner

The utility model relates to a kind of threeway joiner, metal conduit connection technique field.

Existing threeway joiner a kind ofly is provided with screw thread in it, with being connected of pipe, dismantle time-consuming, effort; Another kind is the flange-type threeway, cost height, complex structure, the same existence in succession, the drawback of dismounting inconvenience.

The purpose of this utility model is, provides a kind of simple in structure, and good airproof performance is with being connected of pipe, convenient disassembly, the three-way connector that cost is low.

The purpose of this utility model reaches by the following technical programs.It is made up of three-way body, its special way is, causes on the inwall of this each connection mouth of three-way body and is provided with 2 road circumferential grooves less, and near the inside is seal groove together, near the outside be locking slot together, on the inwall in the locking slot outside, establish N (N 〉=2) axial groove that communicates with it.The width of seal groove can be set as required.Ruo Qinei places an O type or V-shaped seal ring, and its width can be narrower; Ruo Qinei is provided with each one of O type, V-shaped seal ring, and then its width should sell wideer.Circumferential groove on each connection mouth inwall of three-way body is generally 2 roads, if 3 roads, what then have more is generally seal groove together.The bore of each company's mouth of three-way body can be identical, also can be inequality, should design as required.This threeway joiner requires to have several lock dogs on the end circumference of connected tube.

Because the utility model adopted above-mentioned technical solution, make it compared with prior art, have with pipe be connected, dismantle convenient, save time, laborsaving; The setting of seal groove strengthens sealing effect, and simple in structure, easy to manufacture, and cost is low.

The explanation of accompanying drawing drawing

An embodiment's of Fig. 1-the utility model structural representation

The A-A sectional view of Fig. 2-Fig. 1

Another embodiment's of Fig. 3-the utility model structural representation

The A-A sectional view of Fig. 4-Fig. 3

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment 1, with reference to figure 1, Fig. 2.In order more to be clear that and the annexation of pipe, also comprise pipe and seal ring among the figure.The bore of three

connection mouths

20,30,40 of this threeway joiner is identical, and they and three-way body connect as one.Twice circumferential groove on the connection mouth 20, one is seal groove 22,23 embeddings of O RunddichtringO within it, another is a locking slot 21, lock dog 51 cards of pipe on 50 within it.Twice circumferential groove on the connection mouth 30, a seal groove 32,33 embeddings of O RunddichtringO within it, another is a locking slot, pipe 60 lock dog 61 cards within it.Twice circumferential groove on the connection mouth 40, one is seal groove 42,43 embeddings of O RunddichtringO within it, another is a locking slot 41, pipe 70 lock dog 71 cards within it.On the inwall of each connection mouth, evenly laid 4 axial grooves, communicate with locking slot.Communicate with locking slot 21 as 4 axial grooves 24 (Fig. 2) on the connection mouth 20.Connection, unloading process are: make the

lock dog

51,61,71 of managing on 50,60,70 aim at 4 axial grooves of place connection mouth respectively, advance to three-way body 10 directions then, when treating that these lock dogs enter into locking slot and axial groove confluce, swinging head 50,60,70, then lock

dog

51,61,71 snaps into respectively in the

locking slot

21,31,41, thereby finishes the connection procedure with pipe.Desire to make it to separate with connected tube, swinging head 50,60,70 round about then,

lock dog

51,61,71 on it, break away from

locking slot

21,31,41 respectively, and enter axial groove, and groove draws three pipes outward vertically, can reach and the separating of threeway joiner.

Embodiment 2, with reference to figure 3, Fig. 4.The structure of this threeway joiner is substantially the same manner as Example 1.Difference has two, and the one,

seal groove

22,32,42 broads all embed an O RunddichtringO and a V-shaped seal ring; The 2nd, the bore of connection mouth 30 is less than the bore of

connection mouth

20,40, and the bore of

connection mouth

20,40 is identical, compares with embodiment 1, and sealing effect will be better, is suitable for the connection of reducer pipe.With being connected of pipe, unloading process with embodiment 1.

As required, can also provide each connection mouth and have 2,3,5,6 ... the threeway joiner of axial groove or connection mouth be reducing not, and seal groove can hold the threeway joiner of two seal rings; Or the connecting port reducing, and seal groove can only embed the threeway joiner of a seal ring, all belongs to protection domain of the present utility model.

Claims

A kind of threeway joiner, it is made up of three-way body, it is characterized in that, on the inwall of this each connection mouth of three-way body, be provided with 2 road circumferential grooves at least, near the inside is seal groove together, near the outside be locking slot together, on the inwall in the locking slot outside, establish N (N 〉=2) axial groove that communicates with it.
