Description
Technical field
The invention belongs to two siphunculus joint technique field, specifically a kind of variable diameter two siphunculus connector.
Background technique
Two siphunculus connector is the part of connecting line, this is a kind of general name of connector that can be assembled and disassembled in fluid passage,
So that Remote Pipe is transported essential part, be mainly used for liquid, on gas and hydraulic package pipeline connection, lengthen fortune
Defeated distance.
Two siphunculus connector in the prior art, cannot achieve variable diameter function mostly, to realize that variable diameter function, the prior art are big
Mostly use the modes such as ring, hot melt, bonding that pipeline and pipe joint are fixed together, these locking modes due to pipe joint with
Pipeline junction is that shiny surface causes to be not fixed firmly, be easy to cause pipeline fall off or pipe joint and pipeline junction
It is uneven lead to connection after cannot achieve and be fully sealed, and can not quickly be dismantled after connecting, after disassembly to pipeline and
Connector will cause serious damage.
Summary of the invention
In order to make up for the deficiencies of the prior art, it solves two siphunculus connector and realizes change in the case where not damaging pipeline and connector
Diameter, pipeline and connector can not fast assembling-disassembling and poor sealing effects after connection, the problem of being not fixed firmly, one kind proposed by the present invention
Variable diameter two siphunculus connector.
The technical solution adopted by the present invention to solve the technical problems is: a kind of variable diameter two siphunculus of the present invention connects
Head, including tube body；The tube body left end is equipped with sizing interface；The sizing interface is equipped with sealing unit；The tube body right end
