Summary of the invention
For solving the deficiency of above fluid flow control, purpose of the present invention provides a kind of fluid flow and current switch control device, make full use of magnetic fluid and target control fluid difference at aspects such as density, magnetic, effectively control the shape and the behavior of magnetic fluid and target control fluid by magnetic field, reach controlled target control fluid flow size, until making the target control fluid separately fully, implement the purpose of flow control or electric switch.
Convection cell of the present invention and current-controlled switch Design of device scheme are achieved in that this control device comprises a control main body and an accessory device, the control main body comprises a field generator for magnetic, these device two ends are C type structure, on C type structural openings, following two ends are respectively magnetic pole N, S, on C type structural upright side, be wound with the alternating current impression coil, connect with AC power, by changing the size of size of current with controlling magnetic field intensity, between two magnetic poles, be fixed with the rectangular parallelepiped airtight container, magnetic fluid and target control fluid are housed in airtight container, divide up and down and place, add the close encapsulation film between two kinds of fluids, make two kinds of fluids separately, connect with accessory device in its airtight container internal object control fluid both sides, fluid flow control, accessory device is a pipeline, and this pipeline connects (as shown in Figure 1) with the flowmeter and the general pipeline gauge tap of its adaptation.
The another kind of form of this design proposal is the control to the magnitude of current.
Control is in the airtight container in the middle of the magnetic field magnetic fluid and target control fluid to be housed to magnitude of current switch, this target control fluid is a conductive fluid, adopt diaphragm seal that two kinds of fluids are cut off in the middle of same, and at the two ends of conductive fluid with electrode, lead connects, in current circuit, be added with and use electric equipment and power-supply device (as shown in Figure 2), no matter be that the target control fluid is any, fluid flow is identical with the switch controlling device principle of electric current, body takes place in airtight container under the change of magnetic field strength situation magnetic fluid between the magnetic field changes, to reach magnetic fluid to the flow control of target control fluid or the effect of switch.
The used target control fluid of the present invention is selected according to controlling object, and magnetic fluid is according to the density of target control fluid, and physical property such as magnetic property and Control Flow size are selected.
Advantage of the present invention: simple in structure, control flexibly, and is easy to install, is particularly useful for the far distance controlled of the magnitude of current of fluid flow poisonous, that flavor, heavy contamination are arranged or hazardous environment.
