Abstract

The utility model relates to a liquid pipeline plug-in sealing joint, which comprises a sealing ring, a container wall hole and an insertion pipeline. The sealing ring is made of elastic material with the external circumference provided with annular notch, two sides of the notch are provided with radial circular edging, and the container wall hole is provided with axially inward raised circular ring edging. The ring edging is inserted into the annular notch on the sealing ring external circumference when installing and is axially positioned by the annular edging at the two sides of the notch, the insertion pipeline is provided with glabrous external circle, and the external diameter of the insertion pipeline is formed an elastic sealer insertion with the annular notch on the sealing ring inner bore circumference. The utility model has the advantages of steady inserting, convenient installing, reliable sealing and wide application.

Description

Fluid pipeline grafting SEALING FITTING

The utility model relates to pipe coupling, refers in particular to a kind of fluid pipeline grafting SEALING FITTING.

In industrial production and domestic life field, be unable to do without various pipelines, pipeline needs to connect, various all kinds of Placement and corresponding joint are arranged in the prior art, these joints are generally be threaded fixedly connected, but some occasion needs revocable being tightly connected in actual applications, and that for example pegs graft is tightly connected.

The purpose of this utility model provides a kind of fluid pipeline grafting SEALING FITTING, is applied to the grafting sealing of liquid line in connecting, and makes that it is easy to use, it is firm to connect, sealing is reliable.

The utility model is achieved in that

A kind of fluid pipeline grafting SEALING FITTING is made up of seal ring, container wall aperture, grafting pipeline, and seal ring is made with elastic material, be circular, on its excircle annular groove is arranged, there is annular edge radially these groove both sides, on sealing circle endoporus circumference some annular grooves are arranged; There is axial inwardly protruded circular ring limit in the container wall aperture, and this ring limit embeds the annular groove of described seal ring with outer on week during installation, and by the annular edge axially locating of these groove both sides, becomes demountable elastic packing to connect; The grafting pipeline has bright and clean cylindrical, and its external diameter becomes elastic packing to peg graft with annular groove on the described ring inner hole circumference.

In preferred embodiment, the annular groove on the described ring inner hole circumference, its horizontal sanction face has the wedge angle towards container intracavity, and entry end is a fillet.

In most preferred embodiment, the endoporus circumference that annular groove is arranged of described seal ring is the conical surface that less tapering is arranged, and the big end of this conical surface is towards the container wall outside, small end towards between container intracavity.

During enforcement, two radial ringed limits of described seal ring with outer groove both sides, its diameter difference, the annular edge diameter that is installed on the container wall outside is bigger, and the slightly larger in diameter that is installed on less and this annular edge of the annular edge diameter of inboard, container hole choma limit is in the external diameter on container hole choma limit.

The utility model has following actively useful effect:

1. it is firm to peg graft: the dual torus limit that raises up from interior is arranged on the excircle of the seal ring of present technique, this dual torus limit particularly is positioned at the radial ringed limit of container inside the axial rings checkpost of container orifice is lived, it can not be moved axially, thereby realize that seal ring is connected with the firm of container orifice, also make pipeline firm simultaneously to the grafting of ring inner hole.

2. easy for installation: in two radial ring limits of seal ring, the ring limit diameter that is installed on the container wall inboard is less, only is slightly larger than the diameter on container hole choma limit, thereby disassemble or assemble easily, conveniently.

3. sealing is reliable: the annular groove on the ring inner hole circumference of present technique, and its horizontal sanction face has the wedge angle towards container intracavity, and this wedge angle produces the external diameter that resiliently deformable compresses intubate under the fluid pressure effect, prevents fluid seepage, and the better seal effect is arranged.

4. applied range: the SEALING FITTING of present technique can be applicable to industrial production, domestic life field, for example is applied to the glass tube with vacuum of solar water heater and being connected of water storage box, washing machine and being connected of running water pipe etc.

Now in conjunction with the accompanying drawings with preferred embodiment.

Fig. 1 is a splice combinations schematic representation of the present utility model.

Fig. 2 is the container orifice organigram.

Fig. 3 is a kind of embodiment of the utility model seal ring.

Fig. 4 is the partial enlarged drawing of seal ring annular groove among Fig. 3.

Fig. 5 is the another embodiment of the utility model seal ring.

Fluid pipeline grafting SEALING FITTING of the present utility model, form by seal ring 1, container wall aperture 2, grafting pipeline 3 and to see Fig. 1:

Seal ring 1 usefulness elastic material for example rubber is made, and is the circular Fig. 3 of opinion, and annular groove 4 is arranged on its excircle, and there is annular edge 5,6 radially these groove 4 both sides, on sealing circle endoporus circumference some annular grooves 7 is arranged;

Container wall 8 apertures 2 have axial inwardly protruded circular ring limit 7 to see Fig. 2, should embed the annular groove 4 of described seal ring with outer on week in ring limit 9 during installation, and by annular edge 5,6 axially locating of these groove both sides, become demountable elastic packing to connect;

Grafting pipeline 3 has bright and clean cylindrical, and its external diameter is pegged graft with the 7 one-tenth elastic packings of annular groove on the described ring inner hole circumference and seen Fig. 1.

In preferred embodiment, the annular groove 7 on the described seal ring 1 endoporus circumference, its horizontal sanction face has the wedge angle 10 towards container intracavity, and entry end has fillet 11 to see Fig. 4.

In most preferred embodiment, the endoporus circumference that annular groove is arranged of described seal ring is the conical surface 12 that less tapering is arranged, and the big end of this conical surface is towards the outside of container wall 8, and container intracavity 13 is seen Fig. 5 between small end court.

During enforcement, two radial ringed limits of described seal ring with outer groove both sides, its diameter difference, annular edge 5 diameters that are installed on the container wall outside are bigger, are installed on the less and slightly larger in diameter this annular edge 6 of annular edge 6 diameters of 7 inboards, container hole choma limit and see Fig. 1 in the external diameter on container hole choma limit 7.
