Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of oxygen cutting valve, including valve body 1, the end set of valve body 1 has
Spring capping 2, the bottom of spring capping 2 are fixed with spring 3, and the bottom of spring 3 is provided with fixed seat 4, inside fixed seat 4 in
Centre is equipped with worm screw 25, and the side of 25 end of worm screw is provided with feather key 18, and the both sides of worm screw 25 are mounted on worm gear 6, snail
The side of wheel 6 is provided with worm screw 1, and the bottom of worm screw 25 is provided with double and cap 7, and double and cap 7 bottom is provided with push-pull rod
8, the bottom of fixed seat 4 is provided with cylinder 9, and the bottom of cylinder 9 is provided with valve neck 10, and the upper end of cylinder 9 is provided with air inlet 17,
The inside of cylinder 9 is equipped with piston 11, and valve body 1 is internally provided with valve rod 12, valve seat 13 is provided on valve rod 12, valve seat 13
Bottom is provided with spool 14, and valve rod 12 is connected through valve seat 13 with spool 14.
Further, valve neck 10 is tightly connected with valve body 1, ensures the leakproofness and air-tightness of valve.
The surface of fixed seat 4 is equipped with handwheel 16, and handwheel 16 is connected through fixed seat 4 with worm screw 1, facilitates handwheel
Geared worm 1, so as to which worm screw 1 drives worm gear 6 to rotate and worm gear 6.
Push-pull rod 8 is connected through cylinder 9 with valve rod 12, to ensure push-pull rod 8 and valve body 1 and valve rod 12 in fixed seat 6
With one heart so that operational torque steady propulsion is uniform, avoids interior leakage.
Double and cap 7 is sequentially connected with worm screw 25, facilitates and push-pull rod 8, valve rod 12 and spool 14 is driven to transport upward or downward
It is dynamic.
Specifically, the equipment that connection need to use oxygen cutting valve, consistent with prior art connection method, unlike,
When pneumatic：When compressed air is by 9 upper end air inlet of cylinder, piston 11 drives push-pull rod 8, valve rod 12 and spool under gas pressure
14 move down, while spring 3 is gradually compressed, and valve is gradually opened, and stop when piston 11 moves to lower limit position, at this time
Valve is opened completely, and spool 14 moves downward stroke 60mm, and when compressed air is cut off, 9 upper cavity pressure of cylinder is released, push-and-pull
Bar 8, valve rod 12, piston 11 and spool 14 move upwards under the effect of 3 elastic force of spring, and valve progressively closes off, when spool 14 is transported upwards
