Description
Technical field
The utility model relates to a kind of Hall-type flow switch of controllable device switch.
Background technology
In industrial production, much equipment need to be used cooling water and reach production or cooling object, and cooling water is standby by the compression mechanism in cooling-water machine.If supply water while stopping no more than time stop the work of compressor, easily cause loss or the damage of compressor.Therefore need to have the equipment of monitoring streamflow regime to feed back in time coherent signal to controller.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of Hall-type flow switch, for output switching signal, ensures the normal steady operation of cooling-water machine.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
Hall-type flow switch, comprise: water inlet, delivery port and be arranged at water inlet and delivery port between cavity, in described cavity, be provided with magnetic rotor and coordinate the impeller rotating with rotor, described impeller is installed on rotor, the top of described rotor is provided with circuit module, and described circuit module comprises supply module, Hall element and modular converter;
Described supply module, for providing operating voltage to Hall element and modular converter;
Described Hall element, the magnetic field the output pulse signal that produce for responding to vane rotary;
Described modular converter, for described pulse signal is converted to switching signal, and transfers to described switching signal the electronic control module of one cooling-water machine, so that electronic control module is according to the operating state of the compressor of described switching signal control cooling-water machine.
The top of described cavity is provided with dismountable top cover, and described top cover is fixed by screw and cavity.
Compared to existing technology, the beneficial effects of the utility model are: in the time having current through the utility model device, impeller keeps rotating, Hall element output pulse signal, through modular converter, the electric-controlled plate of signal to cooling-water machine opened in output, cooling-water machine is normally worked, in the time there is no current in device, Hall element stops output signal, modular converter output shutdown signal, the electric-controlled plate of cooling-water machine can be made the action of closing compressor for cold water after receiving this signal in time, prevent compressor for cold water damage, device of the present utility model can effectively ensure the fail safe of cooling-water machine work.
Brief description of the drawings

Fig. 2 is the cutaway view of the utility model Hall-type flow switch.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
With reference to figure 1 and Fig. 2, Hall-type flow switch, comprise: water inlet 2, delivery port 1 and be arranged at water inlet 2 and delivery port 1 between cavity 8, in described cavity 8, be provided with magnetic rotor 4 and coordinate the impeller 5 rotating with rotor, impeller 5 is installed on rotor 4, the top of rotor 4 is provided with circuit module, circuit module comprises supply module 7, Hall element 6 and modular converter 3, supply module 7 is for providing operating voltage to Hall element 6 and modular converter 3, Hall element 6 rotates produced magnetic field output pulse signal to modular converter 3 for responding to impeller 5, described modular converter 3 is for being converted to switching signal by described pulse signal, and described switching signal is transferred to the electronic control module of a cooling-water machine, so that electronic control module is according to the operating state of the compressor of described switching signal control cooling-water machine.
Device of the present utility model is for providing the judgement signal of the compressor operating state of controlling cooling-water machine, modular converter 7 is connected with the electronic control module of cooling-water machine, in the time that water inlet 2 and delivery port 1 have current to pass through, current impeller 5 is rotated, impeller 5 drives magnetic rotor 4 to rotate, Hall element 6 senses that magnetic field output pulse signal are to modular converter 3, modular converter 3 converts out pulse signal signal to and exports to the electronic control module of cooling-water machine, and now the compressor of cooling-water machine maintains normal operating conditions; In the time that current stop, impeller 5 and rotor 4 stop operating, Hall element 6 is responded to less than magnetic field and is stopped output pulse signal, while thering is no pulse signal input in modular converter 3, just send the electronic control module of shutdown signal to cooling-water machine, electronic control module is just controlled compressor and is quit work, and prevents compressor damage.
The top of cavity 8 is provided with dismountable top cover 9, and top cover 9 is fixing by screw and cavity 8, and dismountable top cover 9 is convenient to be safeguarded this device.
To one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection range of the utility model claim.
