Abstract
The utility model belongs to the technical field of valve control, in particular to a sparkless electric valve device with a high safety factor. The device is provided with a machine body and a motor arranged in the machine body, a transmission mechanism controlled by the motor, wherein, the transmission mechanism comprises an output shaft connected with a valve and a transmission device arranged on the output shaft, the driving of the motor is controlled by a Hall element, and a process control switch used for controlling process and a torque control switch used for controlling torque are arranged on the Hall element. The device has the advantages of secure operation, reliable working and sparklessness during operation.
Description
Technical field
The utility model relates to technical field of valve control, especially a kind of no-spark, the electric device for valve that safety coefficient is high.
Background technique
At present, the control gear of valve is used very extensive, under coal mine in the central pump house control system, to vacuumize be to adopt Jet injector or vacuum pumping pump to vacuumize mode to water pump mostly in the past, and electromagnetic valve is adopted in pipeline control, owing to adopt electromagnetic valve to have many drawbacks, occurs spark easily, safety coefficient is not high, so rate of fault is higher.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of electric device for valve.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of electric device for valve, have body, be arranged on motor in the body, by the driving mechanism of motor control, driving mechanism includes output shaft that connects valve and the transmission device that is arranged on the output shaft, the driving of motor is controlled by Hall element, rotation by the motor drives transmission device, make output shaft rotate synchronously, thus the open and close of control valve.
Further, in order better to control, Hall element is provided with the travel control switch of control stroke and the torque control switch of controlling torque.
The beneficial effects of the utility model are electric device for valve of the present utility model, security of operation, reliable operation, operation no-spark.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is an overall structure plan view of the present utility model.
1. bodies among the figure, 2. motor, 3. output shaft, 4. transmission device, 5. Hall element.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1, the electric device for valve of preferred forms shown in Figure 2, has body 1, be arranged on the motor 2 in the body 1, driving mechanism by motor 2 controls, driving mechanism includes output shaft 3 that connects valve and the transmission device 4 that is arranged on the output shaft 3, the driving of motor 2 is by Hall element 4 controls, Hall element 5 is provided with the travel control switch of control stroke and the torque control switch of controlling torque, drive the rotation of transmission device 4 by motor 2, make output shaft 3 rotate synchronously, thereby the work that the open and close of control valve, the induction by Hall element 5 simultaneously realize motor 2 with stop.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
