Fig. 1 is front view of the present utility model；
Fig. 2 is positive profile of the present utility model；
Fig. 3 is the profile of A-A in Fig. 1；
Fig. 4 is the profile of B-B in Fig. 3.
Embodiment
The utility model is described in detail with reference to specific embodiment and Figure of description.
As depicted in figs. 1 and 2, dual control safety pneumatic switch provided by the utility model, including application valve body 20 and setting
Main valve body 10 on application valve body 20, in addition to regulation changement, back-stop mechanism and valve element 51.
Regulation changement includes hand-operated valve and is arranged in application valve body 20 and intermeshing rack 33, gear 34,
Hand-operated valve 31 is two and is connected in series, and is connected by gas circuit with application valve body 20, and controls rack 33 to produce displacement, band moving teeth
Wheel 34 rotates.
As shown in Figure 3 and Figure 4, back-stop mechanism is arranged in application valve body 20, including compression spring 41, is arranged on compression bullet
Locating shaft 42 on spring 41 and the camshaft being arranged in gear 34, one end of camshaft are provided with cam 340, and locating shaft 42 is vertical
It is resisted against in camshaft and activity in the locating slot of cam 340.Locating shaft 42 can ensure cam after valve element 51 commutates successfully
Axle, the position of cam 340 are constant, prevent the reciprocal change in location for causing cam 340 due to rack 33.
As shown in figure 3, the bottom of valve element 51 is provided with jacking block 52, top surface is provided with stage clip 53, and valve element 51 is driven in master by jacking block 52
Slided in valve body 10, the back side of cam 340 is integrally formed provided with eccentric rod 341, and main valve body 10 is provided with restriction jacking block 52 and lifted
Vertical slideway, jacking block 52 maintains contact condition all the time under the elastic force effect of stage clip 53 with the top surface of eccentric rod 341.
Jacking block 52 includes apical axis and is arranged on the horizontal block 521 of apical axis bottom, and apical axis is fixed with valve element 51, horizontal block 521
The contact area with eccentric rod 341 can at utmost be increased.
Horizontal block 521 is in Long Circle, and both ends are arc surface, and the shape of arc surface may be such that horizontal block 521 in sliding process
In there is preferable automatic positioning effect, will not shift.
In the present embodiment, illustrate so that one two five logical main valves combine two single-acting control valves as an example.This reality
It is with new operation principle：Start the hand-operated valve 31 of two series connection simultaneously, control rack 33 to slide suitably under gas pressure
Distance, gear 34 rotate corresponding angle, camshaft and the concomitant rotation of cam 340, then eccentric rod of the jacking block 52 in cam 340
341 effect of praising is lower to be risen, and drives valve element 51 to rise to correct position, and gear 34 stops operating, and completes commutation, locating shaft
42 withstand in the presence of compression spring 41 in the locating slot of cam 340, and then source of the gas disconnects, and rack 33 is in back-moving spring 32
Initial position is returned under effect, gear 34 turns round, but camshaft and cam 340 remain stationary as in the presence of check bearing 35,
So that the position of valve element 51 is stable, main valve commutation action is completed.
In the prior art, manually valve 31 promotes rack 33 to move by gas, and rack 33 limits gear 34 and typically makees half
Circular motion, gear 34 move half cycle with moving cam 340, and cam 340 causes valve element 51 to switch station.
Flexible locking pin is provided between compression spring 41 and locating shaft 42.Because gear 34 is under the driving effect of rack 33
When being rotated, locating shaft 42 needs that friction and minor impact occurs with cam 340, and frequently stretching motion, meeting occurs
Generation is radially rocked, and flexible locking pin allows rocking for locating shaft 42, and can guarantee that the company of compression spring 41 and locating shaft 42
Connect good.
Application valve body 20 is vertically arranged with main valve body 10, and the axial direction of gear 34 is vertical with the lifting direction of valve element 51, is saved
Space, and there is good stability.
The utility model, with rack and pinion engagement mechanism, check cam mechanism, spring return mechanism, only by hand during operation
Dynamic operation hand-operated valve, you can realize the reciprocating motion of two positions of valve rod, and then realize Switch of working position, it is necessary to same during operation
When two hand-operated valves of the operating series in gas circuit, it is indispensable, rack is produced reciprocating motion, you can to realize changing for main valve body
To avoiding operator and directly contacted with reversal valve, fundamentally avoid personal injury caused by operator's faulty operation, pole
The big security for improving operator, ensure that the personal safety of operator, can be safe in the environment of safeguard protection is needed
Use, realize manually operated fool-proof design.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn that under enlightenment of the present utility model
The structure change made, it is every that there is same or like technical scheme with the utility model, each fall within guarantor of the present utility model
Within the scope of shield.
