Abstract
A pneumatic valve control mechanism is characterized by comprising a guide arm, a drive air cylinder and a magnetic reversing valve. An air inlet of the magnetic reversing valve is used for compressed air to be fed, and an air outlet is connected with an air inlet of the drive air cylinder. One end of the guide arm is connected with a valve element drive shaft of the valve, the guide arm can rotate around the valve element drive shaft of the valve and is provided with a chute, a slide shaft is installed in the chute, and the slide shaft is connected with a piston rod of the drive air cylinder to jointly form a connecting rod mechanism. The reciprocating motion of the piston rod drives the slide shaft to slide in the chute of the guide arm so as to form the connecting rod motion mechanism, the guide arm is driven to perform reciprocating rotation around the valve element drive shaft of the valve and further open or close the valve, and remote control of the valve is achieved through the magnetic reversing valve. On the basis, the position required to be reached, of the piston rod can be calculated according to the opening degree of the valve, then the position of a proximity switch sensing end on the drive air cylinder is adjusted, and accordingly accurate positioning during valve opening is achieved.
Description
Technical field
The present invention relates to a kind of valve control device, particularly a kind of pneumatic valve control mechanism.
Background technique
In fluid-transporting tubing, valve applications widely, but at present the switch of valve all can only be undertaken by direct control valve rod, can not remote operation; And for some precision type instrument, requiring precision control valve door aperture size, is far from being enough by manually carrying out operated valve operating stem, and therefore current technology have impact on its convenience used to a certain extent, direct control valve uses and compares effort simultaneously, have impact on its ease for use.
Summary of the invention
The invention provides the pneumatic valve control mechanism that a kind of structure is simple, easy to use, without the need to direct control valve, remote operation can realize the opening and closing of valve.Concrete technological scheme is as follows:

Further, drive cylinder to be provided with magnetic approach switch, magnetic approach switch controls the break-make of solenoid directional control valve; Magnetic approach switch comprises magnet and induction end, and magnet is positioned on the piston bottom piston rod, and induction end is positioned at the cylinder body wall driving cylinder.
Further, piston rod part is provided with guide pad, and slide-bar is fixed on guide pad perpendicular to piston rod.
Further, the elongated through hole shape of chute, slide-bar is installed in chute.
Further, solenoid directional control valve is two-bit triplet solenoid directional control valve, and magnetic approach switch connects the electromagnetic coil of two-bit triplet solenoid directional control valve, controls electromagnetic coil energising and power-off.
Pneumatic valve control mechanism of the present invention, the switching of leading arm one end is on the transmission shaft of valve spool of valve, slide-bar is driven to slide in the chute of leading arm by the to-and-fro motion of piston rod, form bar linkage motion mechanism, drive leading arm around the transmission shaft reciprocating rotating of valve spool of valve, and then open or throttle down, the telecontrol of valve is achieved by solenoid directional control valve.
On this basis, driving cylinder installs magnetic approach switch, makes pneumatic valve control mechanism of the present invention possess the function of precision control valve door aperture.The position of piston rod needs arrival specifically can be calculated according to valve opening size, then the position of the proximity switch induction end driven on cylinder is regulated, when sensing the magnet on piston, feedback signal controls the power-off of two-bit triplet electromagnetic coil, cut off air cylinder air source at once, thus realize the accurate location of valve opening.
