Abstract
The utility model relates to a ball valve, particularly to a pneumatic ball valve. The utility model comprises a valve body, a valve core and a valve rod, wherein the valve core and the valve rod are linked, and the valve body is provided with a cylinder. The displacement of a piston rod of the cylinder is linked with the rotation of the valve rod, and a valve switch is controlled by the cylinder, so the ball valve is portable. The movement of the cylinder can also be controlled by an electromagnetic valve or a hand-pulled valve which is arranged outside the cylinder, so the valve switch can be controlled remotely, and the ball valve is convenient in use.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of pneumatic ball valve.
Background technique
Because characteristics such as ball valve has that resistance is little, good seal, switch are rapid, reliability height, so in fluid-transporting tubing, use very extensive, but all can only be undertaken during its switch of present ball valve by the direct control valve rod, and can not operate on it at a distance, influenced the convenience of its use on this is certain, the direct control valve rod uses also relatively effort in addition, has influenced its ease for use.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned ball valve, and provides a kind of easy to use, laborsaving, the pneumatic ball valve that can operate at a distance.
The purpose of this utility model is achieved through the following technical solutions: a kind of pneumatic ball valve, include valve body, spool and valve rod, and spool and valve rod are connected, and described valve body is provided with cylinder, and the displacement of the piston rod of cylinder and the rotation of valve rod are connected.
The utility model further is set to: described valve rod is provided with gear, and piston rod is provided with tooth bar, and rack and pinion is meshed.
The beneficial effects of the utility model are: the switch that comes control valve by cylinder, thereby make it lighter, and the motion of cylinder can come it is controlled by the solenoid valve or the hand valve of outer dress, thereby can control the switch of valve at a distance, thereby convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
As shown in Figure 1 as can be known, the embodiment of a kind of pneumatic ball valve of the utility model, include valve body 1, spool 2 and valve rod 3, spool 2 is connected with valve rod 3, described valve body 1 is provided with cylinder 4, the displacement of the piston rod 42 of cylinder 4 and the rotation of valve rod 3 are connected, both sides at piston 41 respectively are provided with pore 23,24, pore 23,24 respectively are connected with the source of the gas of outside, by to each pore 23,24 ventilation respectively, realize piston 4 reach or after move, thereby make piston rod 41 drive the rotation of valve rod 3, valve is opened or closed, pore 23,24 turnover gas can be controlled by hand valve or solenoid valve, if be applied on fuel tank or the sprinkling truck, when using electromagnetic valve, then the ball valve flange is connected with piping flange, the solenoid valve source of the gas is connected with the automobile cylinder, the coil wire of solenoid valve is taken in the operator cabin, installing switch is may command watering or filling oil again; And if when using hand valve, then hand valve is installed in the driving, the air source hole of hand valve is connected with the automobile cylinder, the driver can drive indoor hand valve control watering or irritate oil like this.
Described valve rod 3 is provided with gear 5, piston rod 42 is provided with tooth bar 6, tooth bar 6 is meshed with gear 5, usually processing for convenience, be that gear 5 is socketed on the valve rod 3, locate with key 7 then, and the tooth bar 6 on the piston rod 42 can be wholely set with piston rod 42, also can split design, and generally speaking, in order to make the accurate engagement of tooth bar 6 and tooth 5, also tooth bar guide groove 8 need be set again, in use, turnover gas by pore 23,24 moves tooth bar 6, thereby driven gear 5 rotates, promptly drive valve rod 3 and rotate, thus the Kai Heguan of realization valve; Certainly, being connected also of valve rod 3 and piston rod 42 can realize by connecting rod or slidercrank mechanism, and connecting rod or slide block promptly are set on piston rod, relative set crank on valve rod, utilize the rotation of the moving belt ovable valve stem of connecting rod or slide block, thereby realize the unlatching and the closure of valve.
Claims (2)
