Technical field
The utility model relates to valve technology field, especially a kind of small-bore motor operated valve of flame-proof mine that is applicable to that the colliery downhole production is used.
Background technology
In the past at underground mine use in fire-fighting, in the central pump house control system of depositing dust, be to adopt jet pump or vacuum pump to come water pump is vacuumized mostly, and solenoid control is adopted in pipeline control usually, because the structural defect that electromagnetic valve exists, make and adopt solenoid control to have many drawbacks, fault rate higher (valve often occurring fits badly), lack valve put in place feedback signal and valve opening signal, can not the hand switch valve under the situation of not having electricity, therefore adopt the solenoid control mode can't satisfy the requirement of colliery industry automation control, people have researched and developed small-bore motor operated valve and replace electromagnetic valve to carry out pipeline control thus, but the worm and gear or the planetary gear kind of drive are adopted in its transmission of electric device that is used for small-bore motor operated valve control at present usually, cause the volume of electric controller own big and heavy, limitation is bigger during installation, noise is bigger during work, transmission is not steady, and positioning control system adopts microswitch to disconnect the mode of drive motors usually, make the cut-off signal that disconnects motor asynchronous, influence the operate as normal of valve with the no source point feedback signal of sending.
The utility model content
The technical problems to be solved in the utility model is: the deficiency that overcomes prior art, provide a kind of flame-proof mine small-bore motor operated valve, its used electric controller volume is little, the cut-off signal of stable drive, motor can keep synchronous consistent with the no source point feedback signal of sending.
The technical scheme that its technical problem that solves the utility model adopts is: the small-bore motor operated valve of a kind of flame-proof mine, comprise valve and coupled electric controller, described electric controller has body, be provided with motor and the transmission mechanism that is connected with motor output shaft in the body, transmission mechanism comprises power transmission shaft and the clock-type multi-stage gear train that is arranged on the power transmission shaft, power transmission shaft one end stretches out outside the body and is connected with valve, also is provided with the Hall element and the circuit control module of control motor rotation in the body.
Further, in order to make the electric controller volume little, stable drive and noise are little, and described clock-type multi-stage gear train is six grades of fine module gear transmissions, gear hierarchal arrangement at different levels, and gearratio is big, and volume is small and exquisite, good looking appearance.
For satisfying the Coal Production requirement of explosion proof, guarantee the motor rotation accurate positioning, described circuit control module comprises the solid-state relay of drive motors and the electronic sensor of control stroke, switching speed is fast, can realize no-spark, noiselessness operation, the safety factor height.
Be the situation of convenient indication valve folding, the other end of described power transmission shaft stretches out the outer indicator of opening that can indicate valve folding situation that also is fixed with of body thereon.
For also can rotating valve under no electric situation, so that the removal system fault also is provided with the manual axle that is connected with clock-type multi-stage gear train on the described body.
The moment of torsion of motor output passes to power transmission shaft after clock-type multi-stage gear train is slowed down, by the opening and closing of power transmission shaft drive valve, because clock-type multi-stage gear train stable drive, so noise is very little; With spanner rotation manual axle, after clock-type multi-stage gear train is slowed down, moment of torsion is passed to power transmission shaft in the time of manually, because speed ratio is big, manually quite light.
The beneficial effects of the utility model are: the utility model adopts clock-type multi-stage gear train to carry out the transmission of moment of torsion, and the circuit control module placed in the body, effectively reduced overall volume, circuit design can guarantee that the cut-off signal of motor is consistent synchronously with the no source point feedback signal of sending, the requirement of explosion proof of Coal Production sparkless operation when having satisfied valve working simultaneously, the utility model stable drive is light and handy, reliable operation, volume is little, in light weight, safety factor and automaticity height.
