Description
Technical field
The utility model belongs to electric device for valve field, particularly a kind of construction of switch for electric device for valve.
Background technique
The Electric actuator application of current valve widely, no matter be industry, agriculture, national defence is most advanced and sophisticated, or the department such as communications and transportation, people's lives all needs a large amount of, various types of electric valve, especially the explosive media environment such as mine, chemical industry, crossing de-iron casing explosion-proof switch is by flame proof slipper push button, realize switch on and off operation, and the easy clamping stagnation of flame proof slide block makes switch cannot action.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the utility model devises a kind of novel explosion-proof switch.The utility model adopts stainless steel, makes the inner Hall element of external magnetic fields, realizes switch on and off operation, structure is simple, switch motion process no-spark, safe and reliable.
The utility model is achieved through the following technical solutions:
The construction of switch of electric device for valve, it comprises valve base, valve base is provided with mounting hole, the non-magnetic pedestal of flame proof is provided with in mounting hole, the inside of non-magnetic pedestal is provided with Hall element, the arranged outside of non-magnetic pedestal has rotary knob, and knob is provided with magnetic element.
Described non-magnetic pedestal adopts stainless steel material or copper material to make.
Described non-magnetic pedestal is fixedly connected in valve base by screw.
In sum, the utility model has following beneficial effect:
The utility model devises a kind of construction of switch of the electric device for valve by Magnetic Induction, the switch that Hall element realizes electric valve device is affected by magnet, overcome the defect that in prior art, flame proof slide block is easily stuck, simultaneously, the utility model realizes switch by Magnetic Induction, in operating process, resistance is little, overcomes the defect of existing operating difficulties, user-friendly.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.Wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the postrotational structural representation of knob;
In figure, 1 is magnetic element, and 2 is knob, and 3 is non-magnetic pedestal, and 4 is Hall element, and 5 is valve base, and 6 is screw.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The construction of switch of electric device for valve as depicted in figs. 1 and 2, it comprises valve base 5, valve base 5 is provided with mounting hole, the non-magnetic pedestal 3 of flame proof is provided with in mounting hole, mining flame proof requirement is met between non-magnetic pedestal 3 and valve base, the inside of non-magnetic pedestal 3 is provided with Hall element 4, the arranged outside of non-magnetic pedestal 3 has rotary knob 2, knob 2 is provided with magnetic element 3, the magnetic element 3 arranged is for affecting with Hall element, when magnetic element rotates the top of Hall element, Hall element is reacted to magnetic signal, realize conducting, when magnetic element leaves Hall element, Hall element does not detect magnetic signal, switch disconnects.
Described non-magnetic pedestal 3 adopts stainless steel material or copper material to make, and stainless steel material and copper material have good magnetic conductivity, can not affect the transmission of signal between magnetic element and Hall element, ensures the normal work of equipment.
Described non-magnetic pedestal is fixedly connected in valve base by screw, adopts stainless steel screw to fix, and is also the transmission effect of the signal ensured between magnetic element and Hall element.
In sum, the utility model has following beneficial effect:
The utility model devises a kind of construction of switch of the electric device for valve by Magnetic Induction, the switch that Hall element realizes electric valve device is affected by magnet, overcome the defect that in prior art, flame proof slide block is easily stuck, simultaneously, the utility model realizes switch by Magnetic Induction, in operating process, resistance is little, overcomes the defect of existing operating difficulties, user-friendly.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
