The diameter-variable sealing ring consists of an outer ring and an inner ring which are compounded integrally, the outer ring has a supporting effect, the inner ring has a sealing effect, and Shore A hardness of the outer ring is larger than that of the inner ring. The diameter-variable sealing ring has a good sealing effect, and is applicable to sealing water tubes with different diameters.
Description
Technical field
The utility model relates to a kind of drinking water pipeline adapter connector sealed member that is used for, and particularly is used for the variable-diameter seal ring of drinking water pipeline adapter connector sealing.
Background technique
In the drinking water pipeline adapter connector, need to use seal ring, at present this type seal ring be generally the O RunddichtringO, its sealing effect is not satisfactory.The material of the same hardness of such O RunddichtringO is processed in addition, and in seal process, the seal ring easy deformation can't be fitted with pipeline, also is the reason that causes sealing effect bad.The ring structure of sealing that to be exactly this type seal ring in addition be need be used the seal ring of different model to the pipeline of different bores, causes the sealing cost to increase.
The model utility content
The technical problem that the utility model will solve provides a kind of good sealing effect, can adapt to the variable-diameter seal ring that is used for the sealing of drinking water pipeline adapter connector of different tube diameters.
The technological scheme that the utility model adopted is following:
The variable-diameter seal ring that is used for drinking water pipeline adapter connector sealing, the cross section of said variable-diameter seal ring is wedgewise structure roughly, the cammed surface of this wedge-shaped structure is a sealing surface.
In a preferred version of the utility model, said variable-diameter seal ring is combined into one with the inner ring that seals by passive outer ring and constitutes, and the shore a hardness of said outer ring is greater than the shore a hardness of said inner ring.
In a preferred version of the utility model, the separating surface of said inside and outside circle is in the neutral position of said cammed surface.
In a preferred version of the utility model; Said variable-diameter seal ring is combined by big seal ring and a short seal ring of a disconnection; An end face of the big seal ring that breaks off is provided with one first convexity, and another end face of the big seal ring that breaks off is provided with and the said first protruding first corresponding pit; An end face of short seal ring be provided with the big seal ring that breaks off on the first protruding second corresponding pit, another end face of lacking seal ring be provided with the big seal ring that breaks off on the second corresponding convexity of first pit.
In a preferred version of the utility model, the shore a hardness of said outer ring is 70～80 degree, and the shore a hardness of said inner ring is 54～60 degree.
The variable-diameter seal ring of the utility model since the cammed surface that adopted wedge-shaped structure as sealing surface; Improved sealing effect; Owing to being combined into one with the inner ring that seals by passive outer ring, it constitutes simultaneously; The hardness of outer ring is greater than the hardness of inner ring, and whole like this seal ring is easy deformation at the seal process middle part, has improved sealing effect.Moreover; The utility model variable-diameter seal ring is made up of the big seal ring of a disconnection and a short seal ring and is formed, and can remove short seal ring for the water pipe of little caliber, and the big seal ring that directly will break off is formed the seal ring of a minor diameter; Water pipe for big caliber then adds short seal ring; Form a large diameter seal ring with the big seal ring that breaks off, avoided the water pipe of different tube diameters need use the seal ring of different size dimensions, reduced cost.

Structural representation when Fig. 1 seals for the utility model is applied to big caliber water pipe;
Fig. 2 is the sectional view of B-B among Fig. 1;
Structural representation when Fig. 3 is applied to the water pipe sealing of tubule footpath for the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to illustrated in figures 1 and 2, the utility model is used for the variable-diameter seal ring 100 of drinking water pipeline adapter connector sealing, and its cross section is wedgewise structure roughly, and the cammed surface 110 of this wedge-shaped structure is a sealing surface.
This variable-diameter seal ring is combined into one with the inner ring 130 that seals by passive outer ring 120 and constitutes; Outer ring 120 employing shore a hardness are that the nitrile butadiene rubber 12263 of 70～80 degree is processed, and inner ring 130 employing shore a hardness are that the nitrile butadiene rubber 12268 of 54～60 degree is processed.The separating surface 160 of inside and outside circle 130,120 is in the neutral position of cammed surface 110.
The variable-diameter seal ring is combined by big seal ring 140 and a short seal ring 150 of a disconnection; An end face 141 of the big seal ring 140 that breaks off is provided with a protruding 141a, and another end face 142 is provided with the pit 142a corresponding with protruding 141a; An end face 151 of short seal ring 150 be provided with the big seal ring 140 that breaks off on the corresponding pit 151a of protruding 141a, another end face 152 of lacking seal ring 150 be provided with the big seal ring 140 that breaks off on the corresponding protruding 152a of pit 142a.
When running into tubule footpath water pipe; Can take away lacking seal ring 150; Two end faces 141,142 butt joint of the big seal ring 140 that directly will break off, the protruding 141a on the end face 141 is inserted in the pit 142a of end face 142 can form a minor diameter seal ring (as shown in Figure 3).
