Abstract

The utility model relates to a valve control device, in particular to a pneumatic control switch device which comprises a cylinder, a rack and a drive gear rotatably connected with a ball valve. A piston rod of the cylinder is fixedly connected with the rack, and the rack is meshed with the drive gear. By means of the arrangement of the rack and the gear, mechanical control of the valve is achieved, and influences brought by manual control are avoided. By means of the control device, automatic control of the valve is achieved, and the problems that the valve is damaged due to manual operations, discharging beats are not stable, and missed opening or missed closing may occur are prevented from occurring.

Description

Pneumatic control switch device
Technical field
The utility model relates to a kind of valve control device, is specifically related to a kind of pneumatic control switch device.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Valve is also divided into cast iron valve according to material, cast steel valve, stainless valve, Cr-Mo steel valve, Chrominm-molybdenum-vanadium steel valve, dual phase steel valve, Plastic valve, the nonstandard customized valve material that waits.Tradition, causes easily valve being damaged owing to adopting operation manually for the valve of fluid flow control, discharge beat is unstable, leak and open or leak the artificial problems such as pass.
Model utility content
The utility model easily damages valve when operating manually in order to solve current valve, discharge beat is unstable, leakage is opened or leak the artificial problems such as pass, and a kind of pneumatic control switch device is provided.This device can be as required according to prior setting automatic-discharging.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of pneumatic control switch device, comprises cylinder, tooth bar and the actuation gear for being rotationally connected with ball valve, and piston rod and the tooth bar of cylinder are connected, tooth bar and actuation gear interlock.By rack and pinion is set, thereby the machinery control to valve, the impact of having avoided manual control to bring have been realized.
As preferably, between described tooth bar and actuation gear, be also provided with driving gear, tooth bar and driving gear interlock, driving gear and actuation gear interlock, the diameter of driving gear is greater than the diameter of actuation gear.Driving gear is greater than actuation gear and can better reduces the stroke of tooth bar, thereby in shorter stroke, realizes the large rotation angle of valve.
As preferably, described cylinder is provided with the relay for control cylinder.Relay can better be realized and set in advance and accurately control.
As preferably, described ball valve is solenoid valve.
Owing to adopting technique scheme, the beneficial effects of the utility model are: realized the automatic control to valve, thereby avoided the artificial damage to valve and consequent discharge beat is unstable, leak and open or leak the generation of the problems such as pass.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: 1 cylinder, 2 tooth bars, 3 actuation gears, 4 driving gears, 5 relays.
Embodiment
With specific embodiment, the utility model is further described below.
Embodiment
A kind of pneumatic control switch device, as shown in Figure 1, comprise cylinder 1, tooth bar 2, driving gear 4 and the actuation gear 3 for being rotationally connected with Solenoid ball valve, cylinder 1 is provided with the relay 5 for control cylinder 1, the piston rod of cylinder 1 is fixedly connected with tooth bar 2, tooth bar 2 and driving gear 4 interlocks, driving gear 4 and actuation gear 3 interlocks, and the diameter of driving gear 4 is greater than the diameter of actuation gear 3.
In use, preset time and the stroke of control, when needs start valve, relay starts cylinder 1, and cylinder 1 is with carry-over bar 2, and tooth bar 2 is with nutating gear 4, then impels actuation gear 3 to rotate, and drives Solenoid ball valve to rotate, and pipeline is controlled.
