Abstract
The utility model discloses an electromagnetic flow switch, including a switch body and a flow driving structure. A cavity is arranged on the upper part of the switch body, the flow driving structure comprises a flow baffle and a magnet, the upper part of the flow baffle is arranged in the cavity, the lower part of the flow baffle is arranged on the outer side of the cavity, the middle part of the flow baffle is mounted on the bottom of the switch body by a pin shaft, an electromagnetic coil is arranged in the cavity, and an electromagnetic coil switch is arranged on the top of the cavity. The structure of the electromagnetic flow switch is simple. When a fluid impacts on the lower part of the baffle, the upper part of the baffle rotates around the pin shaft, the top of the baffle is against the electromagnetic coil switch, thus the electromagnetic coil is conducted, the position of the upper part of the baffle is fixed under the action of the electromagnetic coil, and when the fluid is gradually reduced, the impact on the lower part of the baffle is reduced, the baffle goes far away from the electromagnetic coil switch under the action of gravity, and the electromagnetic coil is disconnected; at the mean time, the baffle quickly resets to cut off the flow due to the action of gravity, and the electromagnetic flow switch is high in control reliability and good in practicability.
Description
Technical field
The utility model belongs to the flow control field, is specifically related to a kind of electromagnetic current reason switch.
Background technology
The flow switch of conventional art generally adopts bellows structure, but the processing technology of bellows structure is complicated, and complexity is installed, and needs welding with firm bellows and switch body, makes the manufacturing cost of flow switch higher, and has the situation of leakage; The flow switch of prior art also has the magnetic material of employing as the flow switch driving element, it mainly adopts is the spring reset structure, yet because spring easily changes, affect the accuracy of switch, and complex structure, along with the continuous improvement of refrigeration air-conditioner, supply equipment, also more and more higher to the requirement of flow switch, the poor reliability of the flow switch of prior art, easily break down.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, high electromagnetic flow switch of control reliability.
the technical scheme that realizes the utility model purpose is a kind of electromagnetic flow switch, comprise switch body and traffic driven structure, described switch body top is provided with cavity, described traffic driven structure comprises and flow baffle plate and the magnet that is arranged on described flow baffle plate top, the top of described flow baffle plate is arranged in described cavity, the bottom of described flow baffle plate is arranged on described switch body bottom outside, the middle part of described flow baffle plate is arranged on the bottom of described switch body by bearing pin, be provided with solenoid in described cavity, described flow baffle plate is arranged in described solenoid, the top of described cavity is provided with solenoid switch, described solenoid switch contacts with described flow baffle plate top movable.
The bottom of described flow baffle plate becomes less than 180 degree with top and greater than the 150 angle settings of spending, described bearing pin is arranged on the corner of described flow baffle plate.
the utlity model has positive effect: of the present utility model simple in structure, when having fluid to pass through, the bottom of fluid impact baffle plate, baffle plate top is rotated around bearing pin, its top props up solenoid switch gradually, make the solenoid conducting, the magnet on baffle plate top keeps baffle position to fix under the effect of solenoid, when fluid reduces gradually, the suffered impulsive force in baffle plate bottom reduces, due to the weight at the baffle plate top electromagnetic force greater than solenoid, when the flow of baffle plate bottom little during to certain value, baffle plate under Action of Gravity Field away from solenoid switch, cutoff solenoid, at this moment, baffle plate is due to a gravitate, therefore accelerate to reset, complete the cutout effect, it is high that it controls reliability, practicality is good.
Description of drawings
For content of the present utility model is more likely to be clearly understood, the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
see Fig. 1, a kind of electromagnetic flow switch, comprise switch body 1 and traffic driven structure 2, described switch body 1 top is provided with cavity 11, described traffic driven structure 2 comprises and flow baffle plate 21 and the magnet 22 that is arranged on described flow baffle plate 21 tops, the top of described flow baffle plate 21 is arranged in described cavity 11, the bottom of described flow baffle plate 21 is arranged on described switch body 1 bottom outside, the middle part of described flow baffle plate 21 is arranged on the bottom of described switch body 1 by bearing pin 3, be provided with solenoid 12 in described cavity 11, described flow baffle plate 21 is arranged in described solenoid 12, the top of described cavity 11 is provided with solenoid switch 13, described solenoid switch 13 contacts with described flow baffle plate 21 top movable.
The bottom of described flow baffle plate 21 becomes less than 180 degree with top and greater than the 150 angle settings of spending, described bearing pin 3 is arranged on the corner of described flow baffle plate 21.
the present embodiment is simple in structure, when having fluid to pass through, the bottom of fluid impact baffle plate, baffle plate top is rotated around bearing pin, its top props up solenoid switch gradually, make the solenoid conducting, the magnet on baffle plate top keeps baffle position to fix under the effect of solenoid, when fluid reduces gradually, the suffered impulsive force in baffle plate bottom reduces, by the weight at the baffle plate top electromagnetic force greater than solenoid, when the flow of baffle plate bottom little during to certain value, baffle plate under Action of Gravity Field away from solenoid switch, cutoff solenoid, baffle plate is due to a gravitate, therefore accelerate to reset, complete the cutout effect, it is high that it controls reliability, practicality is good.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
