The elastic sealing film of bonding gap between body.
Further, the end of the valve body is also machined with the annular mounting groove of indent, is arranged in annular mounting groove
The sealing flap.
Further, the inside edge of the elastic sealing film is Nian Jie with valve base sealing, and outer ledge then protrudes into ring
It adhering and sealing and is compressed by sealing flap in shape mounting groove.Such structure setting can be further improved elastic sealing film to valve body
The sealing effect in gap between valve seat.
Still more preferably, the outside one end of the valve seat is flushed with the bottom of the annular mounting groove.
Further, the sealing flap is fixedly mounted in annular mounting groove by screw.
Further, the spool is rotatably connected on valve inner by upper valve rod and lower valve rod, and the upper valve rod is under
Self-lubricating bearing is provided on valve rod.
Further, the spool upper and lower ends offer cylinder pin hole respectively, and by with the cylinder pin hole
With straight pin spool is mutually fixed respectively with the upper valve rod and lower valve rod.
Further, the spool is connected between upper valve rod and lower valve rod using spline.
Further, sponge cavity is equipped in the self-lubricating bearing, being equipped in the sponge cavity has extruding
The sponge of block, the self-lubricating bearing inner ring are additionally provided with the through-hole being connected with upper valve rod gap.
Compared with prior art, the utility model has the following beneficial effects:
(1), the utility model is disposed with elastic sealing film by the gap location between valve seat and valve body and seals, in this way,
Even if when fluid inlet side at very high pressures when, partially can also be kept off by elastic sealing film along the fluid that gap enters in cavity
Firmly, the gap infiltration between valve seat and valve body, the effective sealability for improving valve be will not continue to.Meanwhile using elasticity
The mode of sealing film will not influence the setting of the packaged type between valve seat and valve body.
(2), good seal performance, V-shaped valve seal receptacle use prefastening force spring, close seal receptacle with spool always, seal
Performance is good, can wear automatic compensating action, long service life to seal receptacle in long-term use.
(3), V-type ball valve core is fixed using upper lower valve rod duplex bearing, and stability is good, and bearing material uses composite material,
Its rolling bearing section uses sintering processes, wear-resisting property with super strength, and has self-lubricating function, thus avoids valve and exist
Phenomenon is killed in long-time service.
(4), V-type ball valve uses the design of monoblock type, leakage caused by avoiding valve body due to using flanged joint.
(5), V-type ball valve core is designed with the v-notch of special shape, and valve is made to have the stream of approximate equal percentage
Flow characteristic.The design makes valve under the premise of with performance is accurately controlled and has very big shearing force and self-cleaning function.
(6), it is connected between valve rod and spool using spline, it is good to neutrality to have, and bearing torque is big, long service life.It adopts
The fit clearance between valve rod and spool is effectively eliminated with spline connection cooperation, the generation in dead zone is avoided, improves valve
Degree of regulation.
