Description
Technical field
The present invention relates to cylinder valve technical field, the straight valve especially filled with cutoff function and electronic intelligence limit.
Background technology
At present, traditional steel cylinder valve air gate be open type threaded connection, i.e., gas cylinder be connected through a screw thread pressure-reducing valve and with
Gas tool connection, when the gas in bottle is finished, and changes gas cylinder, pressure-reducing valve is screwed out, then pressure-reducing valve precession is had the gas cylinder of gas,
Renewal process is cumbersome, complex operation, and installation is bad easily to cause gas to leak.And when changing gas cylinder, always had in cylinder valve
Residual gas leaks, and pollutes air.
Now, some private gas stations are often illegally filled, and traditional cylinder valve also provides just for illegal fill
Profit, it is therefore necessary to increase intelligent charging limiting function for traditional cylinder valve, in order to the thing of steel cylinder under advanced information society's overall situation
Union is managed, and improves the usage safety performance of gas cylinder.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of straight valve filled with cutoff function and intelligently limiting.
Technical scheme used by solve above-mentioned technical problem：A kind of intelligence limit fills spherical straight valve, includes connection steel
The valve body of bottle, it is characterised in that：The valve body is provided with ball check valve and intelligent overfill-limiting valve, and the external port of valve body is provided with soon
Quick coupling, self-closing valve is installed in snap joint.
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 arranged on the pressure ring in valve body, rotate the inner for being installed on body wall
The valve rod of grafting spherical valve core, and it is fixed on the knob of valve rod outer end.
On the basis of the above, the self-closing valve includes the valve opening formed in snap joint, cylindrical valve spool, is fixed on cylindricality
The outer end of valve element can block the valve element pad of valve opening, be fixed on the valve core case of the inner accommodating cylindrical valve spool sliding extension of snap joint,
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 installed in valve body, in valve body
Lower slider can plugging valve hole seat valve opening valve element, keep valve element move up open valve opening trend spring, be secured transverse to valve body
Iron core, slip cap in side wall inserting outside iron core the sensing loop bar that gear valve element moves down and sensing loop bar is kept to be moved away from valve
The spring of core.
Using beneficial effect caused by the present invention：Snap joint can be passed through by being mounted with the steel cylinder of the spherical straight valve of the present invention
Realize that matched pressure-reducing valve quickly connects so that the replacing simple and fast of steel cylinder, securely and reliably.In straight valve
Ball check valve and self-closing valve, it can prevent the residual gas when changing gas cylinder in straight valve from leaking, solve the problems, such as air pollution.
Intelligent overfill-limiting valve in spherical straight valve can effectively prevent the illegal of gas cylinder from filling, and realize Internet of Things management.
Brief description of the drawings
Fig. 1 is the structural representation that present invention intelligence limit fills spherical straight valve.
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 provided with
Ball check valve and intelligent overfill-limiting valve, the external port of valve body 1 are provided with snap joint 2, self-closing valve are provided with snap joint 2.
Snap joint 2 uses primary-secondary type snap joint, 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 changing 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 by force toward filling in gas cylinder
Gas, the pressure of gas can drive intelligent overfill-limiting valve to close, also just can not be toward inflation 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 the both ends of spherical valve core 3 separately with
Ball seat 5, spherical valve core 3, upper ball base 4 and lower ball base 4 are arranged on the pressure ring 6 in valve body 1, rotation is installed on the side wall of valve body 1
The valve rod 7 of inner grafting spherical valve core 3, and it is fixed on the knob 8 of the outer end of valve rod 7.Knob 8 is twisted, band ovable valve stem 7 rotates,
Valve rod 7 drives spherical valve core 3 to rotate, so as to realize the opening and closing of ball check valve.
The self-closing valve includes the valve opening that is formed in snap joint 2, cylindrical valve spool 9, is fixed on the outer end of cylindrical valve spool 9
The valve element pad 10 of valve opening can be blocked, is fixed on the valve core case 11 of the inner accommodating sliding extension of cylindrical valve spool 9 of snap joint 2, and
Compression spring 12 between cylindrical valve spool and 9 valve core cases 10.When connecting pressure-reducing valve, the female joint of pressure-reducing valve can head on post
Shape valve element 9 is retracted, and makes valve opening normally opened, so as to connect straight way (line) valve and pressure-reducing valve.When pulling down pressure-reducing valve, cylindrical valve spool 9 is in spring 12
Effect is lower to stretch out, and blocks valve opening, can effectively prevent the interior gas leak of straight valve.
The intelligent overfill-limiting valve include installed in valve body 1 inner port valve opening seat 13, can in what is slided up and down in valve body 1
The valve element 14 of the valve opening of plugging valve hole seat 13, valve element 14 is kept to move up the spring 15 of opening valve opening trend, be secured transverse to the side of valve body 1
The sensing loop bar 17 and holding sensing loop bar inserting gear valve element 14 and move down of iron core 16, slip cap outside iron core 16 in wall
17 are moved away from the spring 18 of valve element 14.During legal inflation, intelligent charge gun recognize electronic mark on gas cylinder it is effective after, start electricity
Magnetic flux generator, induced field is formed around iron core, drive sensing loop bar 17 to shift to valve element 14, and inserted and keep off valve element 14, make valve
Core 14 can not move down the valve opening in shutoff valve hole seat 13, and intelligent overfill-limiting valve is open mode, and now charge gun can be toward filling in gas cylinder
Gas.During illegal inflation, intelligent charge gun can not read effective electronic mark, and electromagnetic generator does not work, if by force toward gas
To be inflated in bottle, the pressure of gas can promote valve element 14 to move down the valve opening in shutoff valve hole seat 13, and intelligent overfill-limiting valve is closed mode,
Thus can not be toward inflation in gas cylinder, so as to effectively prevent from illegally filling.
