Specific embodiment
The embodiment of the utility model is described further below in conjunction with the accompanying drawings.
The specific embodiment 1 of the pipeline jointing construction of the utility model, as shown in Figure 1 to Figure 3, pipeline jointing construction includes
Joint body 1, the first connecting tube 2, the second connecting tube 3, connector sleeve 4 and cutting ferrule 5.It is set in structural body there are two mounting hole 12,
The extending direction of two mounting holes 12 is mutually perpendicular to, and is mutually perpendicular to be connected on joint body 1 two connecting tubes, is connect at this time
Head ontology 1 plays the role of elbow.
As shown in figure 3, the mounting hole 12 of joint body 1 includes being used for for the thread segment of the connection of connector sleeve 4 and in spiral shell
The path section 13 of line end front end is equipped with seal section between thread segment and path section 13, seal section has sealing surface 11, in this implementation
Sealing surface 11 is the taper surface of opening outwardly in example, and the front end of thread segment is equipped with unthreaded hole section, is formed between unthreaded hole section and seal section
Step, for the end top pressure for cutting ferrule 5, the size of unthreaded hole section and the size fit of cutting ferrule are so that cutting ferrule can be in unthreaded hole section
Guiding movement.The unthreaded hole section of mounting hole 12 i.e. at 5 corresponding position of cutting ferrule be equipped with air vent 14, air vent 14 it is a diameter of
2.5mm, the inside and outside wall surface of 14 penetrating mounting holes 12 of air vent, so as to which the gas leaked at the position be enable to discharge removing,
The pressure that leaked gas is formed at this is avoided, which to apply active force to connector sleeve 4 and connecting tube, reduces connecting tube and joint body
1 seal pressure.
As shown in Fig. 2, the end that the first connecting tube 2 is connect with joint body 1 is eccentric ball head structure, outside eccentric ball head
Surface forms the mating surface 21 for coordinating with the sealing surface 11 of the taper on joint body 1, when eccentric ball head and sealing surface connect
Line contact is formed when touching, increases the contact between two sealing mating surfaces 21 in this way, is enhanced at sealing mating surface 21
The pressure that can be born increases the bearing capacity of pipeline jointing construction.
Connector sleeve 4 and cutting ferrule 5 form the connector sleeve component for providing connecting tube fastening force, in connecting tube and connector sheet
The end that body 1 connects is equipped with external screw thread, and internal thread is equipped in the endoporus of cutting ferrule 5, and cutting ferrule 5 is mounted on connecting tube by helicitic texture
On.The helicitic texture of cutting ferrule 5 is left hand thread.Connector sleeve is including for the tightening portion tightened and for being connect with joint body 1
Connecting portion, connecting portion is equipped with the external screw thread that be adapted to the thread segment of mounting hole 12, i.e. connector sleeve passes through helicitic texture with pacifying
Dress hole 12 connects, and the helicitic texture of connector sleeve is right-handed thread.Escape is equipped between tightening portion and connecting portion, that is, thread segment, with
Make connecting portion completely into in mounting hole.
During installation, first cutting ferrule 5 is screwed in connecting tube, the end in connecting tube is made to have the exposing of two button screw threads, again will later
Connector sleeve is tightened in across connecting tube on joint body 1, since the helicitic texture on the helicitic texture on connector sleeve and cutting ferrule 5 revolves
To on the contrary, would not be that cutting ferrule 5 loosens when tightening connector sleeve.It tightens rear connector sleeve and compression is applied to connecting tube by cutting ferrule 5
Power makes the eccentric ball head top pressure of connector sleeve make the contact shape between two sealing surfaces on the sealing surface of the taper of joint body 1
It is contacted into line, the seal pressure that can be born is to ensure that under smaller mounting torque, reduces joint body with connecting
Mounting torque between pipe is contacted using line between two sealing mating surfaces, and the accuracy of manufacture of butt joint ontology and connecting tube will
It asks relatively low, solves caused by existing pipeline jointing construction needs the higher accuracy of manufacture using cone match sealing and be manufactured into
The technical issues of this is high.
