The utility model discloses a terminal seal structure of pipeline through C type buckle, pipe box, sealed lid, rubber seal, sealed cooperation of filling up etc. Has strengthened the sealing performance of pipeline end.
Description
Technical field
This utility model relates to a kind of sealing structure, particularly relates to a kind of pipe end and seals structure.
Background technology
Existing pipe end seals and mainly uses threaded cover body structure to realize connecting, and during seal operation, needs to use the structures such as substantial amounts of sealing gasket, helicitic texture can be avoided leakage occur.Additionally, when carrying liquid material, corrosion situation easily occurs in pipeline, cover body structure is caused to be not easy dismounting.
Utility model content
The purpose of this utility model is: provide a kind of pipe end carrying pipeline high sealing performance to seal structure.
This utility model is achieved through the following technical solutions: pipe end seals structure, including sealing lid, pipeline body, flange and having resilient c-type buckle, described pipeline body is set with pipe box, and described sealing is placed on the end of pipeline body；It is provided with rubber seal at described pipe box, pipeline body and the sealing lid three place of cooperation and is combined with corresponding sealing gasket；Described flange sleeve is equipped with the part covered near sealing on pipe box, and the top and bottom of described c-type buckle are respectively fitting into sealing cap upper surface and the lower surface of flange.
It is combined with sealing ring between described flange and sealing lid.
The end face width bottom surface of the ring body of described sealing ring is narrow so that the lateral surface of ring body is lozenges；Between described flange and sealing lid, it is provided with the thickness hold-down ring less than sealing ring thickness, this hold-down ring is provided with the lozenges coordinated with sealing ring lozenges；It is provided through flange at described flange bottom and holds out against the screw of hold-down ring.
Described sealing cap upper surface is provided with draw-in groove, and the upper end of described c-type buckle coordinates in this draw-in groove.
Described pipe box uses copper material to make.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) pipe end of the present utility model seals structure, by the cooperation of c-type buckle, pipe box, sealing lid, rubber seal, sealing gasket etc., enhances the sealing property of pipe end.
(2) sealing ring arranged further enhancing sealing property.Hold-down ring coordinates with sealing ring, can further strengthen sealing property.
(3) upper end of c-type buckle coordinates in draw-in groove, is possible to prevent c-type buckle to slip, improves stability.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that pipe end of the present utility model seals structure；
In figure, 1 pipeline body, 2 pipe boxes, 3 seal lid, 4 sealing rings, 5 sealing gaskets, 6 flanges, 7 sealing rings, 8 hold-down rings, 9 screws, 10 draw-in grooves, 11 c-type buckles 11.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1:
As it is shown in figure 1, pipe end of the present utility model seals structure, including sealing lid 3, pipeline body 1, flange 6 and having resilient c-type buckle 11, described pipeline body 1 being set with pipe box 2, the described lid 3 that seals is placed on the end of pipeline body 1；It is provided with rubber seal 4 at described pipe box 2, pipeline body 1 and the sealing lid 3 three places of cooperation and is combined with corresponding sealing gasket 5；Described flange 6 is set with on pipe box 2 near the part sealing lid 3, and the top and bottom of described c-type buckle 11 are respectively fitting into sealing lid 3 upper surfaces and the lower surface of flange 6.Pipe end of the present utility model seals structure, by c-type buckle 11, pipe box 2, the cooperation of sealing lid 3, rubber seal 4, sealing gasket 5 etc., enhances the sealing property of pipe end.During use, first install pipeline body 1 and pipe box 2, then sealing gasket 5 and rubber seal 4 are loaded, then lid top cover labyrinth 3, finally install c-type buckle 11 and push down sealing lid 3, for sealing compared with helicitic texture, improve sealing property, and corrosion will not be produced and cause sealing lid to open difficulty.
Embodiment 2:
As preferably, it is combined with sealing ring 7 between described flange 6 and sealing lid 3, further increasing sealing property.In rubber seal 4 and sealing ring 7 one, the setting outside, improves sealing property on the whole.
Embodiment 3:
As preferably, the end face width bottom surface of the ring body of described sealing ring 7 is narrow so that the lateral surface of ring body is lozenges；Between described flange 6 and sealing lid 3, it is provided with the thickness hold-down ring 8 less than sealing ring 7 thickness, this hold-down ring 8 is provided with the lozenges coordinated with sealing ring 7 lozenges；It is provided through flange 6 in described flange 6 bottom surface and holds out against the screw 9 of hold-down ring 8.During use, by turn screw 9, hold-down ring 8 being moved up, the lozenges of hold-down ring 8 applies active force to the lozenges of sealing ring 7 so that sealing ring 7 is more close to seal lid 3 and pipe box 2, thus improves sealing property.
Embodiment 4:
As preferably, described sealing is covered 3 upper surfaces and is provided with draw-in groove 10, and the upper end of described c-type buckle 11 coordinates in this draw-in groove 10, is possible to prevent coming off of c-type buckle 11.It should be noted that the groove coordinated with c-type buckle 11 lower end can also be arranged on flange 6, prevent c-type buckle 11 from slipping.It should be noted that the lower end of described c-type buckle 11 can withstand on screw 9, increase tightening force, improve sealing property further.
Embodiment 5:
As preferably, described pipe box 2 uses copper material to make, and has corrosion resistant effect, it is therefore prevented that pipeline body 1 is corroded.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
