The content of the invention
For the deficiency that above-mentioned ball valve is present, technical purpose of the invention is to provide a kind of ON/OFF for controlling simply, with a cylinder control valve, the pneumatic ball valve more linear to the control of valve rod, this pneumatic ball valve is laborsaving when causing controlled valve, installs the space for needing smaller.
The present invention is achieved through the following technical solutions：
A kind of pneumatic ball valve, the pneumatic ball valve includes:Valve rod, valve rod frame, the valve rod is arranged in valve rod frame, the valve stem top is provided with control-rod, the control-rod is connected with piston rod, and the piston rod is connected with piston, and the piston is installed in the cylinder, the piston rod, piston, the center line of cylinder are set to circular arc, the piston rod, piston, the center line of cylinder circular arc radius it is identical, the center of circle is identical, the cylinder, piston rod centerline central angle be 90 °.
Further, the control-rod is straight hollow stem, and one end of the control-rod is connected by lock tube with valve rod, and the other end of the control-rod is solderable or is connected with piston rod by lock tube.
Further, the piston rod is the hollow stem of circular arc, and the material of the piston rod is metal material, and the piston rod is welded on the end face center of circle of piston.
Further, two end faces of the cylinder are provided with air inlet, and tracheae is connected with the air inlet, and the tracheae is provided with valve, and the tracheae is connected with air accumulator, and the material of cylinder is aluminum alloy material.
Further, the material of the piston is aluminium alloy, central angle θ≤30 ° of the centerline of the piston.
The beneficial effects of the invention are as follows:
1st, by the way that control-rod will be provided with valve rod, the pneumatic equipments such as control-rod and piston rod are connected, so that the pneumatic control that is controlled to valve rod, the air pressure of pneumatic control is from air accumulator so that pneumatic control need not at any time open compressor or can not configure compressor；
2nd, it is set to circular arc by by the center line of control-rod, cylinder, piston and piston rod, compared with prior art, the quantity of cylinder is less, and piston rod acts on power on control-rod all the time perpendicular to radius where control-rod so that the power of piston rod is converted into the moment of torsion of valve rod to greatest extent；
3rd, it is set to hollow stem by by control-rod and piston rod so that whole control device is lighter, and more material-saving, cost is lower.
4th, aluminum alloy material is set to by by cylinder and piston, the overall weight of pneumatic means can be reduced, piston is lighter so that the control of piston is more flexible.
Brief description of the drawings
Fig. 1 is the structural representation of invention.
Marked in figure：1 is valve rod, 2 is cylinder, 3 is control-rod, 4 is piston, 5 is piston rod, 6 is valve rod frame.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
A kind of pneumatic ball valve as shown in Figure 1, the pneumatic ball valve includes：Valve rod 1, cylinder 2, control-rod 3, piston 4, piston rod 5, valve rod frame 6, the valve rod 1 is arranged in valve rod frame 6, the top of the valve rod 1 is provided with control-rod 3, the control-rod 3 is connected with piston rod 5, the piston rod 5 is connected with piston 4, the piston 4 is arranged in cylinder 2, the piston rod 5, piston 4, the center line of cylinder 2 are set to circular arc, the piston rod 5, piston 4, the center line of cylinder 2 circular arc radius it is identical, the center of circle is identical, and the cylinder 2, the central angle of the centerline of piston rod 5 are 90 °；
Wherein, the power of piston rod 5 is converted into the control-rod 3 of installation the torque acted on valve rod 1, piston rod 5, piston 4, the cylinder 2 of circular arc shape are by being provided with center line, cylinder 2, the central angle of the centerline of piston rod 5 are 90 °, enable control over valve rod 1 and rotate 90 ° of positions to off/on, cause that piston rod acts on the power on control-rod all the time perpendicular to radius where control-rod simultaneously so that the power of piston rod is converted into the moment of torsion of valve rod to greatest extent.
