On the basis of the above, the ball check valve includes spherical valve core, sets up the upper ball base at spherical valve core both ends separately
And lower ball base, spherical valve core, upper ball base and lower ball base are mounted on the in vivo pressure ring of valve, rotate the inner end for being installed on body wall
The valve rod of grafting spherical valve core and the knob for being fixed on valve rod outer end.
On the basis of the above, the self-closing valve includes the valve opening being formed in quick coupling, and cylindrical valve spool is fixed on cylindricality
The outer end of spool can block the spool pad of valve opening, be fixed on the valve core case that quick coupling inner end houses cylindrical valve spool sliding extension,
And the compression spring between cylindrical valve spool and valve core case.
On the basis of the above, the intelligent overfill-limiting valve includes the valve opening seat of the inner port mounted on valve body, in valve body
Lower slider can plugging valve hole seat valve opening spool, keep spool move up open valve opening trend spring, be secured transverse to valve body

The spring of core.
Using advantageous effect caused by the utility model：Being mounted with the steel cylinder of the straight valve of spherical shape of the utility model can pass through
Quick coupling realizes that matched pressure reducing valve quickly connects so that the replacement of steel cylinder is simple and fast, securely and reliably.It is mounted on
Ball check valve and self-closing valve in straight valve, can prevent the residual gas when replacing gas cylinder in straight valve from leaking, and it is dirty to solve air
The problem of dye.Intelligent overfill-limiting valve in spherical straight valve can effectively prevent the illegal of gas cylinder from filling, and realize Internet of Things management.
Description of the drawings
Fig. 1 is that the utility model intelligently limits the structure diagram for filling spherical straight valve.
Specific embodiment
As shown in Figure 1, a kind of intelligence limit fills spherical straight valve, include the valve body 1 of connection steel cylinder, the valve body 1 is equipped with
Ball check valve and intelligent overfill-limiting valve, the external port of valve body 1 are equipped with quick coupling 2, self-closing valve are equipped in quick coupling 2.
Quick coupling 2 uses primary-secondary type quick coupling, realizes the quick connection of spherical straight valve and pressure reducing valve.Ball check valve and self-closing valve
It can be beneficial to prevent the gas leak in valve body and pipeline when replacing gas cylinder.During legal inflation, intelligent charge gun recognizes gas cylinder
On electronic mark it is effective after, start calutron, prevent intelligent overfill-limiting valve closing motion, charge gun can be toward inflating in gas cylinder.
During illegal inflation, intelligent charge gun can not read effective electronic mark, and calutron does not work, if being filled by force in gas cylinder
Gas, the pressure of gas can drive intelligent overfill-limiting valve to close, and also can not just be inflated in gas cylinder, so as to prevent illegally to fill.
Specifically, the ball check valve includes spherical valve core 3, set up the upper ball base 4 at 3 both ends of spherical valve core separately under
Spherical valve core 3, upper ball base 4 and lower ball base 5 are mounted on the pressure ring 6 in valve body 1 by ball seat 5, and rotation is installed on 1 side wall of valve body
The valve rod 7 of inner end grafting spherical valve core 3 and the knob 8 for being fixed on 7 outer end of valve rod.Knob 8 is twisted, band ovable valve stem 7 rotates,
Valve rod 7 drives spherical valve core 3 to rotate, so as to fulfill the opening and closing of ball check valve.
The self-closing valve includes the valve opening being formed in quick coupling 2, and cylindrical valve spool 9 is fixed on the outer of cylindrical valve spool 9
End can block the spool pad 10 of valve opening, be fixed on the valve core case 11 that 2 inner end of quick coupling houses 9 sliding extension of cylindrical valve spool, with
And the compression spring 12 between cylindrical valve spool 9 and valve core case 10.When connecting pressure reducing valve, the female connector of pressure reducing valve can head on
Cylindrical valve spool 9 is retracted, and makes valve opening normally opened, so as to connect straight way (line) valve and pressure reducing valve.When removing pressure reducing valve, cylindrical valve spool 9 is in spring 12
Under the action of stretch out, block valve opening, can effectively prevent the interior gas leak of straight valve.
It is described intelligence overfill-limiting valve include mounted on valve body 1 inner port valve opening seat 13, can in what is slided up and down in valve body 1
The spool 14 of 13 valve opening of plugging valve hole seat keeps spool 14 to move up the spring 15 of opening valve opening trend, be secured transverse to valve body 1
Iron core 16, sliding sleeve inserting outside iron core 16 sensing loop bar 17 and holding sensing set that gear spool 14 moves down in side wall
Bar 17 is moved away from the spring 18 of spool 14.During legal inflation, intelligent charge gun recognize electronic mark on gas cylinder it is effective after, start
Electromagnetic generator forms induced field around iron core, and sensing loop bar 17 is driven to shift to spool 14, and inserts and keep off spool 14, makes
Spool 14 can not move down the valve opening on close valve orifice seat 13, and intelligent overfill-limiting valve is in an open state, and charge gun can be in gas cylinder at this time
Inflation.During illegal inflation, intelligent charge gun can not read effective electronic mark, and electromagnetic generator does not work, if past by force
Inflation in gas cylinder, the pressure of gas can promote spool 14 to move down the valve opening on close valve orifice seat 13, and intelligent overfill-limiting valve is closing shape
State can not thus inflate in gas cylinder, so as to effectively prevent from illegally filling.
