Abstract
The present invention discloses a kind of spherical straight valve, includes the valve body of connection steel cylinder, and the valve body is provided with ball check valve, and the external port of valve body is provided with snap joint, self-closing valve is provided with snap joint.Being mounted with the steel cylinder of the spherical straight valve of the present invention can realize that matched pressure-reducing valve quickly connects by snap joint so that the replacing simple and fast of steel cylinder, securely and reliably.Ball check valve and self-closing valve in straight valve, it can prevent the residual gas when changing gas cylinder in straight valve from leaking, solve the problems, such as air pollution.
Description
Technical field
The present invention relates to cylinder valve technical field, the especially straight valve with cutoff function.
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.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of straight valve with cutoff function.
Technical scheme used by solve above-mentioned technical problem：A kind of spherical straight valve, include the valve body of connection steel cylinder,
It is characterized in that：The valve body is provided with ball check valve, and the external port of valve body is provided with snap joint, installed in snap joint
There is self-closing valve.
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.
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.
Brief description of the drawings
Fig. 1 is the structural representation of the spherical straight valve of the present invention.
Embodiment
As shown in figure 1, a kind of spherical straight valve, includes the valve body 1 for connecting steel cylinder, the valve body 1 is provided with spherical cut-off
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 is fast using primary-secondary type
Quick coupling, realize the quick connection of spherical straight valve and pressure-reducing valve.Ball check valve and self-closing valve can be beneficial to prevent when changing gas cylinder
The only gas leak in valve body and pipeline.
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.
