Driving effect.Control system can be placed in a box body, and this box body is referred to as valve switch box, its work
Principle is as follows:
Power gas enters in valve switch box, first carries out air pressure instruction, then by a needle valve 20,
The effect of this needle valve 20 is the flow controlling power gas, and power gas reduces, and enters air motor 1 blade
The speed in space the most just slows down, and the rotating speed of such air motor 1 will slow down, but the pressure of power gas
Do not reduce, so the moment of torsion that valve drives can't reduce.Switch knob 22 includes valve opening state, closes valve
State and zero-bit state, when switch knob 22 is positioned at valve opening position 23, high torque valve driving device is in out
Valve state, high torque valve driving device drives hand-operated valve valve opening；When switch knob 22 is positioned at pass valve position 24
Time, high torque valve driving device is in close valve state, and high torque valve driving device drives hand-operated valve to close valve；When completing
After valve opening and pass valve events, switch knob 22 being placed in zero position 25, now, power gas is to high torque valve
Driving device hermetic seal, so can reduce the loss of power gas, reduces running cost.Valve switch box is permissible
Being designed to single valve control, it is also possible to be designed to bivalve control (see Fig. 4), single valve controls to may be used for pressure
Valve operation of transmitter controls, and bivalve controls may be used for two valve operation controls of differential pressure transmitter
System.
Now with expanding economy, various process units scales are increasing, and process pipelines is increasingly thicker,
The hand wheel position of manually-operated gate is more and more higher, has a lot of handwheel installation site to allow operator be difficult to operation,
Along with the requirement of safety management improves, higher in manually-operated gate handwheel installation site, people does not utilize other to ascend a height
When equipment just cannot be carried out switching manipulation, it is stipulated that require to need support of setting for this platform, and built at support
Cheng Hou, through the examination of safety management department, just will can carry out the switching manipulation of valve, the expense that wastes time and energy warp
Take.And through the technological transformation of the present invention, hands valve hand wheel uses high torque valve driving device to replace, valve switch
Box may be mounted at the easily operated place away from manually-operated gate, high torque valve driving device and valve switch box
Between use gas source conduit connect.Therefore people just can the most easily realize the switch of hands valve, from
And decrease cost of labor and improve processing safety.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art, can be easily in the technical scope that the invention discloses
The change expected or replacement, all should contain within protection scope of the present invention.Therefore, the protection of the present invention
Scope should be as the criterion with scope of the claims.
