Description
Technical field
The present invention relates to seal for pipe joints fields, specifically for the release-resistant sealing structure connected between bellows.
Background technique
Bellows is widely used in arranging because of the advantages that crushing resistance is good, project cost is low, light-weight, quick construction facilitates
Water field.In order to facilitate transport, the length of every section of bellows can not be made too long, all be to transport to building site to carry out again when installing
Connection.The connection type of existing bellows is generally plug-in type or flange join type.The connection type of plug-in type are as follows: in socket end
Rubber seal is installed at second trough and coats lubricant, is then inserted directly into bellmouth, and it is noted that bellmouth will be against the current
Direction is flowed, socket wants Parallel to the flow direction.This connection type, since sealing ring is flexible, sealing ring will drive tubing after insertion
Axial rebound, makes sealing effect be deteriorated, and there are also the later period because geology settles, can generate pulling force to tubing, disengage tubing.And flange
Connection type will then have more many connecting components such as flange, bolt assembly, installation trouble, project cost height.
Summary of the invention
The purpose of the present invention is to provide the release-resistant sealing structure connected between a kind of bellows, the bellmouths of the bellows component
