A kind of concrete prioritization scheme, one of them sealing ring is positioned at connecting tube and is plugged in one end and the groove floor of groove
Between, another one sealing ring is positioned on the outer circumference surface of one end that connecting tube is plugged in groove.
A kind of concrete prioritization scheme, the outer circumference surface of one end that described connecting tube is plugged in groove is provided with annular
Groove, the sealing ring being positioned on connecting tube outer circumference surface is arranged on cannelure.
It it is one as the quantity of sealing ring described in a kind of prioritization scheme.
A kind of concrete prioritization scheme, described sealing ring be positioned at connecting tube be plugged in groove one end and groove floor it
Between.
The present invention takes above technical scheme, has the advantage that connecting tube and one end of joint body grafting and groove
It is provided with sealing ring between bottom surface, sealing ring in the cannelure of one end that connecting tube is plugged in groove, can also be provided with, even
Take over one end of joint body grafting and groove floor between arrange sealing ring be hardly damaged, substantially increase connecting tube with
The sealing of joint body junction, joint body and the junction good airproof performance of connecting tube, be difficult to permeability phenomenon occur, significantly
Reduce maintenance cost, extend the service life of oil connection.
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
