Abstract
A pipeline connecting end sealing device is used for pipeline connecting end sealing. The pipeline connecting end sealing device comprises two pipe ends connected together. The pipe ends are externally provided with an upper connecting piece and a lower connecting piece which are matched with each other, an elastic sealing piece is arranged between the upper connecting piece and the lower connecting piece, a groove is formed in the bottom of the lower connecting piece, and the upper portion of the elastic sealing piece and the groove in the bottom of the lower connecting piece are provided with an upper seal ring and a lower seal ring respectively. The upper connecting piece and the lower connecting piece are tightly connected through a bolt. The upper portion of the elastic sealing piece is provided with a groove, and the upper seal ring is arranged in the groove in the upper portion of the elastic sealing piece. The pipeline connecting end sealing device has the advantages that the connecting ends of a pipeline are better protected, and the leakage phenomenon is reduced.
Description
Technical field
The utility model is for the sealing of pipeline connection end.
Background technique
In the work progresss such as chemical industry, oil, heat supply, often can use pipeline connection each other.In Large Construction, if pipeline does not need to change in a short time, general that the joint of pipeline termination is integrally welded, prevent that it from occurring leakage phenomenon.But situation is to adopt screw thread or flange to connect mostly, and joint adopts the inner encapsulating method that adds seal ring or sealing gasket.But along with vibrations appear in time lengthening or pipeline, can cause joint area to become flexible and occur leaking.
Summary of the invention
The purpose of this utility model is to provide a kind of pipeline connection end seal arrangement, adopts outside seal method, reduces pipe joint joint and produces leakage.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of pipeline connection end seal arrangement, comprise two pipe ends that link together, it is characterized in that: at described pipe end, be provided with upper connector and the lower link cooperatively interacting outward, between described upper connector and lower link, be provided with elastomer seal, in lower link bottom, be provided with groove, in elastomer seal top and lower link bottom groove, be respectively equipped with seal ring and lower seal.
Above-described upper connector and lower link are bolted connection.
Above-described elastomer seal top is provided with groove, and described upper seal ring is arranged in the groove on elastomer seal top.
The beneficial effects of the utility model are, the connection end of pipeline has been played to better protective action, have reduced and have occurred the phenomenon of leaking.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. pipe end; 2. go up seal ring; 3. elastomer seal; 4. descend link; 5. lower seal; 6. bolt; 7. upper connector.
Embodiment
From accompanying drawing 1; the utility model provides a kind of connection end to pipeline to play the seal arrangement of seal protection effect; outside interconnective pipe end 1, to be provided with upper connector 7 and the lower link 4 cooperatively interacting; between described upper connector 7 and lower link 4, be provided with elastomer seal 3; in lower link 4 bottoms, be provided with groove, in elastomer seal 3 tops and lower link 4 bottom grooves, be respectively equipped with seal ring 2 and lower seal 5.Elastomer seal 3 described in the utility model can adopt teflon prefabricated component, on described elastomer seal 3 tops, is provided with groove, and described upper seal ring 2 is arranged in the groove on elastomer seal 3 tops.Above-described upper connector 7 and lower link 4 are fastenedly connected by bolt 6.
The utility model can be used for the pipe end that any mode connects, such as employing is threaded or flange connection.When the pipe end that adopts flange to connect is sealed, due to the elastic reaction of elastomer seal 3, adpting flange can well be wrapped up, its effect is obvious equally.
Claims (3)
1. a pipeline connection end seal arrangement, comprise two pipe ends that link together, it is characterized in that: at described pipe end, be provided with upper connector and the lower link cooperatively interacting outward, between described upper connector and lower link, be provided with elastomer seal, in lower link bottom, be provided with groove, in elastomer seal top and lower link bottom groove, be respectively equipped with seal ring and lower seal.
2. pipeline connection end seal arrangement according to claim 1, is characterized in that: described upper connector and lower link are bolted connection.
