Abstract
The utility model relates to a flow switch. The flow switch includes a housing which forms a float chamber, and the housing is provided with two outlets and an inlet which are interconnected with the float chamber, wherein the inlet is disposed in the lower portion of the housing, and two outlets are respectively disposed in the lower portion and the upper portion of the housing; the float chamber forms a communicating vessel, a longitudinal core body is disposed in the float chamber; and a magnetoelectric contact is disposed in a cavity of the core body, and the periphery of the core body is sleeved a float cooperating with the magnetoelectric contact. When a liquid flows into the inlet, the liquid level in the float chamber rises, and the float raises together to switch on the magnetoelectric contact; and when there is no flow, gas flows back into the float chamber through the outlet in the upper portion of the housing, the liquid level declines and the float returns to switch off the magnetoelectric contact. A tiny flow can start the switch, and the flow switch is high in sensitivity, simple in structure and convenient to choose materials.
Description
Technical field
The utility model relates to a kind of flow detector, is particularly useful for the detection of tiny flow quantity, specifically, relates to a kind of sensitive flow switch that responds.
Background technology
In the passage of much liquid or gas transport, need use traffic switch, as in gas heater, need to carry out to control according to the break-make of current by flow switch the switch of coal gas.At present, conventional flow switch is controlled by spring, needs starting pressure during work, during lower than starting pressure, do not work, when flow hour, be difficult to reach the starting pressure of flow switch, cause flow switch to work.
Utility model content
The technical problems to be solved in the utility model is for above deficiency, and a kind of flow switch is provided, and has overcome the low defect of flow switch sensitivity in prior art, adopts after flow switch of the present utility model, has advantages of highly sensitive.
For solving above technical problem, the utility model by the following technical solutions: a kind of flow switch, is characterized in that: described flow switch comprises airtight housing, and housing is provided with communication port, is provided with core body in housing;
In described core body, be provided with magnetoelectricity contact, core body is set with the float coordinating with magnetoelectricity contact outward.
, described communication port comprises import, the first outlet and the second outlet.
Another kind of prioritization scheme, described import is positioned at the bottom of housing.
Another prioritization scheme, described the first outlet is positioned at the bottom of housing.
Further prioritization scheme, described the second outlet is positioned at the top of housing.
Prioritization scheme further, described the first outlet and the second outlet are positioned at the homonymy of housing.
The utility model adopts after above technical scheme, compared with prior art, have the following advantages: housing is provided with import and the outlet being communicated with float chamber, import is arranged on the bottom of housing, described outlet is provided with two, two outlets are separately positioned on bottom and the top of housing, float chamber forms a kind of linker, in float chamber, be provided with core body longitudinally, in the cavity of core body, be provided with magnetoelectricity contact, the periphery of core body is set with the float matching with magnetoelectricity contact, while having liquid to enter in import, float indoor liquid rises, float rises thereupon, magnetoelectricity contact is connected, when flow is zero, the outlet of gas through housing top refluxes and enters float chamber, and liquid level declines, float return, and magnetoelectricity contact disconnects, and small flow gets final product starting switch, highly sensitive, and simple in structure, draws materials conveniently.
Below in conjunction with drawings and Examples, the utility model is elaborated.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of flow switch in the utility model embodiment;
In figure,
1-float chamber, 2-float, 3-import, 4-the first outlet, 5-the second outlet, 6-magnetoelectricity contact, 7-housing, 8-core body.
Embodiment
Embodiment, as shown in Figure 1, a kind of flow switch, comprise airtight housing 7, in the cavity of housing 7, be provided with core body 8 longitudinally, core body 8 is hollow shape, in the cavity of core body 8, be provided with magnetoelectricity contact 6, described magnetoelectricity contact 6 is positioned at the top of core body 8, the periphery of core body 8 is set with float 2, float 2 is made by magnetic material, for coordinating with magnetoelectricity contact 6, between core body 8 and housing 7, enclose float chamber 1, the bottom of housing 7 sidewalls is provided with import 3 and the first outlet 4 being communicated with float chamber 1 respectively, the top of housing 7 sidewalls of the first outlet 4 homonymies is provided with the second outlet 5, the effect of described the second outlet 5 is to make float chamber 1 form linker, import 3, the latus rectum of first outlet the 4 and second outlet 5 calculates acquisition according to actual needs.
While having liquid flow in housing 7, liquid enters float chamber 1 through import 3, because the liquid entering through import 3 has certain pressure, water inlet flow velocity is greater than Water discharge flow speed, liquid level in float chamber 1 rises, and float 2 rises along core body 8, when float 2 rises to the induction range of magnetoelectricity contact 6, magnetoelectricity contact 6 is connected, and the interior unnecessary gas of float chamber 1 or liquid are discharged by the second outlet 5;
When fluid flow is zero, because float chamber 1 is a kind of linker, gas is back to float chamber 1 through the second outlet 5, and liquid level declines, and float 2 also declines thereupon, and magnetoelectricity contact 6 disconnects.
The above is giving an example of the utility model preferred forms, and the part of wherein not addressing is in detail those of ordinary skills' common practise.Protection range of the present utility model is as the criterion with the content of claim, and any equivalent transformation carrying out based on technology enlightenment of the present utility model, also within protection range of the present utility model.
