Abstract
The utility model relates to a sojourn in car domestic water way field, especially relate to a pipeline seal structure. A strenghthened type pipeline seal structure, includes passive connecting pipe, sealing plug and initiative connecting pipe, the open end of passive connecting pipe is provided with the first step and the second step of the increase along the axial from interior outside successive layer, the body of sealing plug is cylindrical, and the front end of body is provided with the round boss, cooperate with the inner circle of first step in the outer lane of boss, cooperate with the internal diameter of initiative connecting pipe in the outer lane of body, outer wall and the first step of initiative connecting pipe cooperate, seal through primary seal circle interference fit between the outer wall of initiative connecting pipe and the second step, the body all is provided with the embedded annular groove that has inferior sealing washer with the outer lane of boss. The utility model discloses how the connecting pipe of no matter taking the initiative is tailor, and the sealed face that the sealing plug corresponds can not receive the influence, has saved the leak hunting - mode of reprocessing that adopts in the current production, has simplified the installation jobs flow.
Description
Technical field
The utility model relates to field, lodging vehicle domestic water road, particularly relates to a kind of pipe sealing structure.
Background technique
In prior art, water pipe and pipe fitting use an O type circle to seal, and this sealing means exists following shortcoming:
1, because supplying pipe is softer, water pipe is easily because pressure factor becomes ellipticity in transport and using process are crossed, and so just there will be deviation from circular from and exceed standard, now the sealing effect of O type circle will be affected, and occurs leaking;
2, pipeline can carry out cutting as required in installation process, and during cutting, end is subject to shear pressure and there will be distortion equally, causes deviation from circular to exceed standard.
Therefore, find in actual use, only use the sealing of O type circle, disposable fitting tight can not realize 100%, and sealing reliability is not high, needs a kind of new sealing configuration.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of reinforced pipe sealing structure by sealing plug transition two connecting pipeline, the sealing surface of sealing plug is provided with extra seal ring, no matter initiatively connecting tube how cutting, the sealing surface that sealing plug is corresponding all can not be affected, ensure that the sealing of pipeline assembly is qualified, simplify installation exercise flow process.
The utility model is achieved in that a kind of reinforced pipe sealing structure, comprise passive connecting tube, sealing plug and initiatively connecting tube, the opening end of described passive connecting tube is provided with the first step and second step that from inside to outside successively increase vertically, the body cylindrical of described sealing plug, the front end of body is provided with a circle boss, match with the inner ring of first step in the outer ring of described boss, the outer ring of described body is closed with the diameter compatible of active connecting tube, the outer wall of described active connecting tube matches with first step, by primary seal circle interference fit seal between the outer wall of active connecting tube and second step, the annular groove of time seal ring is embedded with together with described body is all provided with the outer ring of boss.
The front end of described boss is provided with the chamfering of convergent.
The rear end of described body is provided with the chamfering of convergent.
The reinforced pipe sealing structure of the utility model is by sealing plug transition two connecting pipeline, the sealing surface of sealing plug is provided with extra seal ring, no matter initiatively connecting tube how cutting, the sealing surface that sealing plug is corresponding all can not be affected, the sealing of two passages can realize a fitting tight and reach 100%, eliminates the leak detection that adopts in existing production-reprocess pattern, ensures that the sealing of pipeline assembly is qualified, simplify installation exercise flow process, improve manufacturing efficiency.

In figure: 1 passive connecting tube, 2 sealing plugs, 3 initiatively connecting tube, 4 primary seal circles, 5 seal rings, 11 first steps, 12 second steps, 21 bodies, 22 boss.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As Fig. 1, shown in 2, a kind of reinforced pipe sealing structure, comprise passive connecting tube 1, sealing plug 2 and initiatively connecting tube 3, the opening end of described passive connecting tube 1 is provided with the first step 11 and second step 12 that from inside to outside successively increase vertically, the body 21 of described sealing plug 2 is cylindrical, the front end of body 21 is provided with a circle boss 22, match with the inner ring of first step 11 in the outer ring of described boss 21, the outer ring of described body 21 is closed with the diameter compatible of active connecting tube 3, the outer wall of described active connecting tube 3 matches with first step 11, by primary seal circle 4 interference fit seal between the outer wall of active connecting tube 3 and second step 12, the annular groove of time seal ring 5 is embedded with together with described body 21 is all provided with the outer ring of boss 22.
When installing connection, first sealing plug 2 is inserted in passive connecting tube 1, the front end of the boss 22 of sealing plug 2 is made to prop up the bottom of first step 11, then the body 21 active connecting tube 3 being sleeved on sealing plug 2 is outer and be inserted in passive connecting tube 1, and making the front end of initiatively connecting tube 3 prop up the rear end of boss 22, sealing plug 2 and passive the connecting tube 1 and secondary seal ring 5 initiatively between connecting tube 3 matches with primary seal circle 4 and forms multi-pass and seal the effect that improve sealing.
In the present embodiment, as shown in Figure 3, for the ease of the insertion of sealing plug 2 with active connecting tube 3, the front end of described boss 22 is provided with the chamfering of convergent, and the rear end of described body 21 is provided with the chamfering of convergent.
