The olderly flowage of pressure oil realizes the transmitting of power.How easily to realize the connection of pipeline in hydraulic system, and guarantees connection place
Leakproofness, be construct hydraulic circuit a critical issue.
Currently, the major way that pipeline couples in hydraulic system can be divided into two classes：It is fixedly connected and detachably couples.
It is fixedly connected (such as：Welding) belong to disposable connection, disassembly destroys connection；
Detachable connection can be divided into end face seal connection and thread seal connection again.
End face seal connection be by the flange face of the flange face of one end pipeline and other end pipeline by screw bolt and nut or
Screw attachment is integral, and sealing element is placed between two flange faces, realizes the sealed attachment of both ends pipeline, end face seal
There are certain deviations for the central axes for two flange faces that connection allows to be coupled to each other, but must keeping parallelism；When mutually interconnecting
When two flange faces connect are not parallel, it is easy to cause the sealing material discontinuity being clipped between two flange faces, causes to let out
Leakage；
Thread seal is coupled through the phase of outer (interior) screw thread and interior (outer) screw thread on other end pipeline on the pipeline of one end
Mutually cooperation couples the pipeline at both ends integrally, and thread seal connection is higher to the position accuracy demand of both ends pipeline, it is desirable that phase
It the central axes of the two class screw threads mutually cooperated must be on same straight line；When the central axes of mutually matched two classes screw thread exist compared with
When little deviation, stress concentration is easy to produce at thread connection, and under certain conditions (such as：Elevated Gravity) it this answers
Power concentration can be amplified, and influence the reliability of connection；It, can when the central axes of mutually matched two classes screw thread are there are when relatively large deviation
It can not couple.
