Abstract
The utility model relates to a pipeline connection device which comprises a pipeline sealing element which is arrange in a pipe base and is connected with pipe elements, the pipeline sealing element is a drum-shaped podetium whose outer wall is a drum-shaped face, and a ring gutter is arranged on one end face of the drum-shaped podetium. The structure of the utility model solves the deficiency that a conventional sealing ring of the prior arts adopts has bad sealing effect, and is easy damaged and the like, and has excellent effect of surface sealing and end face sealing, and the life span is long, the structure is simple and the manufacture is easy.
Description
Technical field
The utility model relates to a kind of connection set, the especially a kind of stainless steel pipe of band bulge loop and assembling pipe joint that base links into an integrated entity of making.
Background technique
Traditional metal tube connects adopt more and is threaded or the groove Placement, and these connections must be carried out cutting to the port of pipe fitting, therefore has defectives such as destroying, weaken pipe end intensity.For guaranteeing pipe end intensity, tubing is reserved machining allowance when producing, the wall thickness of tubing is greatly increased, and has wasted a large amount of metallic material.The bulge loop pipe fitting connects the wall thickness that then can effectively reduce tubing; protection body port intensity; reduce cost; be not specifically designed to the seal arrangement of the stainless steel pipe of being with bulge loop when being connected but still has at present with base; defectives such as some Sealings that come from the improvement of conventional seals circle exist sealing effect poor, and are fragile.
The model utility content
Defectives such as the purpose of this utility model provides a kind of assembling pipe joint, is used for being connected of pipe fitting and base, effectively solves prior art and uses the conventional seals circle to exist sealing effect poor, and is fragile.
To achieve these goals, the utility model provides a kind of assembling pipe joint, comprise being arranged in the base and the conduit seals that is connected with pipe fitting that described conduit seals is that an outer wall is the planar cydariform cylinder of cydariform, an end face of described cydariform cylinder is provided with circular groove.
Further, described circular groove is an arc groove shape circular groove, and the end of described base is provided with step, or the end of described base is provided with the circuitous portion of arcuation.
On the technique scheme basis, described pipe fitting is provided with bulge loop, is provided with pressing plate between described bulge loop and the conduit seals, and described pipe fitting is a stainless steel pipe.
The utility model provides a kind of assembling pipe joint of new structure, will connect into assemblying body with the stainless steel pipe and the base of bulge loop by a conduit seals.Conduit seals is that an outer wall is the planar cydariform cylinder of cydariform, and end face is provided with circular groove, has surface of good and end face seal performance.Because taked abovementioned technology, the utility model to compare to have good sealing effect with the conventional seals circle, long service life, simple in structure, make characteristics such as easy.In addition, use the utility model can further reduce the wall thickness of tubing, reduce tubing and produce cost.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Embodiment
First embodiment
Fig. 1 is the utility model first embodiment's a structural representation.As shown in Figure 1, the utility model assembling pipe joint comprises base 6, pipe fitting 10 and conduit seals 2, and conduit seals 2 is arranged in the base 6 and with pipe fitting 10 and is connected to form assemblying body.Wherein, conduit seals 2 is that an outer wall is the planar cydariform cylinder of cydariform, and an end face of cydariform cylinder is provided with circular groove 3, forms the rubber-like sealing lip between base 6 and pipe fitting 10.The outer wall of cydariform cylinder and circular groove 3 make outer surface have elasticity, therefore have good face seal performance.The end of base 6 is provided with step 5, with the end face formation end face seal of cydariform cylinder.Circular groove 3 can improve sealability of the present utility model to greatest extent for arc groove shape circular groove.
Second embodiment
Fig. 2 is the utility model second embodiment's a structural representation.As shown in Figure 2, the utility model assembling pipe joint comprises base 6, pipe fitting 10 and conduit seals 2, and conduit seals 2 is arranged in the base 6 and with pipe fitting 10 and is connected to form assemblying body.Wherein, conduit seals 2 is that an outer wall is the planar cydariform cylinder of cydariform, specifically, is that a cross section is subcircular or oval-shaped cydariform cylinder, and an end face is provided with circular groove 3, forms the rubber-like sealing lip between base 6 and pipe fitting 10.The circuitous portion 4 of arc is arranged in the end of base 6, and the planar outer wall of cydariform of arc inner wall and cydariform cylinder fits tightly, and therefore has good face seal performance and end face seal performance.Circular groove 3 can improve sealability of the present utility model to greatest extent for arc groove shape circular groove.
The 3rd embodiment
Fig. 3 is the utility model the 3rd embodiment's a structural representation, the structural representation when being to use state.As shown in Figure 3, when the utility model uses, pipe laying Sealing 2 and pressing plate 7 on base 6, the stainless steel pipe 10 insertion bases 6 that an end had bulge loop 8 can be finished installation.Stainless steel pipe is generally the stainless steel fluid hose.Specifically, pressing plate 7 is close to the internal surface of base 6 with the cydariform face of cydariform cylinder 1, and its sealing lip 9 is close to the outer surface of stainless steel pipe 10 simultaneously, plays seal action, nut 11 is socketed in outside the base 6, the end face of stainless steel pipe 10 is pressed close to the step 5 that is provided with in the base 6.Because taked abovementioned technology, the utility model to compare to have good sealing effect with the conventional seals circle, long service life, simple in structure, make characteristics such as easy.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
