It encloses, prevents the fuse because in the excessive direct unlatching core shell of pressure, and annular groove is installed by being equipped on gag lever post, and
It installs and is equipped with sealing ring in annular groove, then improve the leakproofness between core shell and gag lever post, gag lever post is placed in one end in core shell
With retaining ring contradict, be arranged using the above structure so that piston rod arrive predetermined position when, persistently guarantee gag lever post and core shell between
Sealing effect, improve practical function.
The utility model is further arranged to: the retaining ring and the resistance surface that the sealed core conical surface contradicts are oblique, and with
The gradient of tapered surface is identical.
By using above-mentioned technical proposal, retaining ring and the resistance surface that the sealed core conical surface contradicts are oblique, and and tapered surface
Gradient it is identical, be arranged using the above structure, by the skewed resistance surface being arranged on retaining ring, between inclined-plane and inclined-plane
It is larger to contradict area, to improve the sealing effect between retaining ring and sealed core.
The utility model is further arranged to: the sealed core is equipped with the body of rod, and spring is placed on outside the body of rod, locking member and bullet
The side end face that spring contradicts is equipped with limiting slot, and one end of spring is placed in limiting slot.
By using above-mentioned technical proposal, sealed core is equipped with the body of rod, and spring is placed on outside the body of rod, sets using the above structure
It sets, the stability of the connection cooperation between sealed core and spring, and the limiting slot being equipped on locking member is improved, by spring
One end be placed in limiting slot, then improve the limit effect to spring, and ensure the stability of the movement of sealed core, into
And improve good sealing effect.
Detailed description of the invention
Fig. 1 is a kind of partial cross-sectional structural diagram of air blowing control mechanism embodiment of the utility model.
Appended drawing reference in figure, 1- start spool, 10- core shell, 11- sealed core, the 110- body of rod, 12- locking member, 120- outlet
Hole, 121- limiting slot, 13- spring, 14- retaining ring, 2- pressure-control valve, 20- gag lever post, 21- sealing ring.
Specific embodiment
A kind of air blowing control mechanism embodiment of the utility model is described further referring to Fig.1.
A kind of air blowing control mechanism, including starting spool 1 and pressure-control valve 2, pressure-control valve 2 include core shell 10 and
