Abstract
The utility model relates to a shutoff device which can be matched with various valves and is used as a fast switching device, and the shutoff device comprises a driving gear and an output gear which are mutually engaged and connected by a rudder gear, wherein the driving gear is driven by a miniature motor, and the output gear and a switching shaft of an electrical valve are coaxially arranged. A unidirectional rotating device and a swing rod are arranged on a rudder gear shaft, and two motor micro-switches for limitation, elastic winding devices and the shifting pins of the micro-switches are additionally arranged on a gear disk of the output gear at certain intervals. When the utility model works, the miniature motor drives the driving gear to rotate in a front direction or a reverse direction mode, and also drives an output shaft of the output gear to open or shut off valves. When the valves are opened or shut off in place, the shifting pins touch one of the micro-switches so as to switch off power supply.
Description
Affiliated technical field
The utility model belongs to valve control switch technical field, relates to a kind ofly can supportingly being used for various big flow gas control valve doors and making the cutoff device that fast-switching arrangement uses.
Background technique
Two kinds of electric valve separated motor valve that release is at present used and solenoid valves.When using under heavy caliber or mesohigh pipeline, solenoid valve can be accomplished quick shutoff, but needs the power electricity to support, owing to strict requirement of explosion proof occasion arranged many, use the valve working occasion as gas pipeline with the control of IC-card gas meter, do not allow to use the power electricity, thereby solenoid valve just can't use; And adopt the low voltage motor valve to cooperate speed reducer to drive, and cause switch motion slow again, quick-closing valve is also made troubles to use soon.
The model utility content
The purpose of this utility model is to overcome the problem that prior art exists, and a kind of rational in infrastructure, easy to operate, quick cutoff device that can use low pressure (below the 6V) electric valve under the mesohigh pipeline is provided.
Be used to realize that the technical solution of foregoing invention purpose is such: the quick cutoff device of the electric valve that is provided has the driving gear and one and the coaxial mounted output gear of electric valve switch axle that are driven by micro motor, between described two gears by the connection that is meshing with each other of a rudder gear, an one-way rotation device and a fork are housed on the rudder gear shaft, wheel disc periphery at output gear adds two spacing motor sensitive switches of using surely at interval, and elasticity rolling-in device and sensitive switch finger are housed on the wheel disc of output gear.During micro motor for driving driving gear forward rotation, driving gear and then the rotation of driving rudder gear driven output gear, output gear drives output shaft rotating opening valve thereupon, in the valve opening process, output gear is also tightened elasticity rolling-in device when rotating, and makes it accumulation of energy, when valve open puts in place, finger touches a sensitive switch, cuts off the electricity supply.During micro motor for driving driving gear backward rotation, because the one-way rotation device is housed on the rudder gear, the rudder gear can not counterrotating, therefore will make the fork backward rotation, and rudder gear and output gear be thrown off, so elasticity rolling-in device will drive the output shaft backward rotation of output gear, rapid-closure damper, after valve closing put in place, the finger on the output gear touched another sensitive switch, cuts off the electricity supply.
Compared with prior art, the utlity model has following advantage:
1, valve can have the self-sustaining ability in any enable possition, need not the power supply support;
2, valve can be realized moment pass valve in any enable possition;
3, only need dryelement cell to drive the reliable switch that micro motor can drive valve;
4, moment closes valve and only needs minimum electric energy, can utilize capacitor discharge to close valve.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model.
Fig. 2 is the plan view of Fig. 1.
Embodiment
As shown in the figure, the quick cutoff device of this electric valve is made of micro motor 1, speed reducer 2, driving gear 3, fork 4, rudder gear 5, one-way rotation device 6, output gear 7, output shaft 8, elasticity rolling-in device 9, finger 10 and two sensitive switches 11,12.Wherein micro motor 1 drives driving gear 3 rotations by speed reducer 2, and driving gear 3 is by rudder gear 5 and output gear 7 engagement driving, the one-way rotation device 6 that fork 4 is housed on rudder gear 5 and is made of unilateral bearing or single direction ratchet; When micro motor 1 drive driving gear 3 is done backward rotation, because the cause of one-way rotation device 6 is housed on the rudder gear 5, driving gear 3 will make fork 4 counterrotatings, and rudder gear 5 and output gear 7 are thrown off; Output shaft 8 control valves of output gear are closed, surely add two spacing motor sensitive switches 10 and 12 of using at interval in output gear 7 wheel disc peripheries, elasticity rolling-in device 9 and sensitive switch finger 11 are housed on the wheel disc of output gear 7, and said elasticity rolling-in device 9 can be made of torsion spring or clockwork spring.During output gear 7 forward rotation, output shaft 8 drives valve opening, elasticity rolling-in device 9 rolling-in accumulation of energys simultaneously, and when valve opening put in place, finger 11 touched sensitive switch 10, cuts off the electricity supply; After rudder gear 5 was thrown off with output gear 7, elasticity rolling-in device 9 was released and can be driven output gear 7 backward rotation, rapid-closure damper, and when valve closing put in place, finger 11 touched sensitive switch 12, cuts off the electricity supply.
