Problems solved by technology
[0002] In order to transport the medium, bellows are usually used for transportation. The bellows joint is used to connect the bellows, which requires high sealing performance. The existing bellows joints have poor sealing performance and short service life, and the existing bellows The joints are all placed outside, and there is no antifreeze device on the bellows joints. Cold weather causes the bellows in the bellows joints to freeze, making it difficult to use the bellows, which will cause certain damage to the bellows itself and increase maintenance costs. Unable to meet the normal use of bellows in winter

The invention discloses a multipurpose corrugated pipe joint which comprises a joint body. The joint body is of a hollow structure; a mounting groove is formed in the joint body; a sealing sleeve is arranged in the mounting groove; a limiting outer ring is arranged at the right end of the sealing sleeve; a limiting inner ring is arranged at the left end of the sealing sleeve; a corrugated pipe canbe connected into the joint body; the corrugated pipe is connected into the joint body through the limiting inner ring and the limiting outer ring; an anti-freezing device is arranged on the joint body and comprises a first heat preservation layer, a resistance wire, a second heat preservation layer and a vacuum heat insulation layer; the first heat preservation layer is laid on the outer wall ofthe joint body; the resistance wire is laid between the first heat preservation layer and the outer wall of the joint body; the second heat preservation layer is laid on the outer side of the first heat preservation layer; and the vacuum heat insulation layer is laid between the first heat preservation layer and the second heat preservation layer. According to the corrugated pipe joint provided by the invention, reliable sealing can be achieved, and connection is convenient and rapid.
Description
technical field [0001] The invention relates to the field of pipe fittings, in particular to a multi-purpose corrugated pipe joint. Background technique [0002] In order to transport the medium, bellows are usually used for transportation. The bellows joint is used to connect the bellows, which requires high sealing performance. The existing bellows joints have poor sealing performance and short service life, and the existing bellows The joints are all placed outside, and there is no antifreeze device on the bellows joints. Cold weather causes the bellows in the bellows joints to freeze, making it difficult to use the bellows, which will cause certain damage to the bellows itself and increase maintenance costs. It cannot meet the normal use of bellows in winter. Contents of the invention [0003] In order to solve the problems of the technologies described above, the present invention provides the following technical solutions: [0004] The invention provides a multi-pu...
