Core assembly includes spool and the fuse that is mounted on spool, and spool is by the handwheel outside valve rod connection valve body, in the drive of handwheel
Dynamic lower valve core assembly moved up and down in valve chamber realization separated with valve seat with it is closely sealed, to realize the opening and closing of cylinder valve,
The spool is equipped with upper and lower perforative balance hole, and the balance hole is connected to valve chamber upwards, and balance hole connects with venthole downwards
It is logical.
Pressure cap is arranged in the valve chamber top, and the pressure cap is connect by screw thread with valve body, and valve rod is arranged inside pressure cap.
The safety relief device includes the safety relief mouth being connected to air inlet, rupture disk, is pressed on rupture disk
Safe plug screw, wherein rupture disk uses edge flanging form.
Corresponding outlet interface bottom is provided with the anti-misloading limited block of protrusion at the venthole.
The beneficial effects of the utility model：
1, the utility model spool is equipped with upper and lower perforative balance hole, and under the operating condition of 40MPa super-pressure, cylinder valve is opened
Instantaneous pressure gas can be filled into valve chamber by balance hole, pressure difference will not be formed in lower valve chamber space on core assembly,
Reduce the frictional force in opening process at core assembly and valve chamber matching thread, resistance when cylinder valve is opened can be effectively reduced.
2, the outlet interface bottom of the utility model is equipped with the anti-misloading limited block of protrusion, is allowed to subtract with dedicated 40MPa
Depressor and gas-charging connection matching, can effectively avoid the misloading of the gas of different pressure levels, misuse, reduce safety hazards.
3, the rupture disk of the utility model safety device uses the form of edge flanging, and rupture disk is avoided to overlap,
It can effectively prevent rupture disk and occur the more dresses of two panels or two panels or more in an assembling process and actual burst pressure is caused to increase at double
The problem of, it is ensured that the safety that cylinder valve uses.

Specific embodiment
With reference to the drawings and specific embodiments, the utility model is described in further detail.It should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, having read the utility model instruction
Content after, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms are equally fallen
In range defined herein.
As shown in attached drawing 1,2, the utility model includes valve body 17, valve rod 2, pressure cap 13, core assembly, safety relief dress
It sets, handwheel 1, valve body 17 is equipped with intake interface 12, outlet interface 14, and intake interface 12 is equipped with air inlet 11, outlet interface 14
Equipped with venthole 15, valve chamber 7 is set in valve body 17, mobilizable core assembly is installed in valve chamber 7, core assembly passes through valve
Handwheel 1 outside 2 connection valve body of bar, in the valve seat 7 of 3 bottom of valve chamber setting protrusion, valve seat 7 is communicated with air inlet 11, the valve
Core assembly includes spool 4 and the fuse 6 that is mounted on spool, and 4 upper end of spool connects valve rod 2, in the driving bottom spool of handwheel 1
Component can be moved up and down along valve chamber 3 realization separated with valve seat 7 with it is closely sealed, to realize the opening and closing of cylinder valve, set on spool 4
