Abstract
The utility model discloses a liquid level controller which comprises a fixed block and a plurality of probes which vertically penetrate through the fixed block, wherein the lengths of the probes extending out of the fixed block are different; the probes are connected to an input circuit of a relay; an output circuit of the relay is connected to an input circuit of a transformer; and an output circuit of the transformer is connected to a water pump control circuit. The liquid level controller has a simple structure, is low in manufacturing cost, convenient to popularize, high in sensitivity, low in fault rate and high in reliability and can be widely applied to matching and mounting of new water pumps and improvement of old water pumps.
Description
Technical field
The utility model relates to the device of control water level.
Background technology
Fluid level controller is used to control the liquid level of Water storage container; Ball float at present commonly used carries out liquid level monitoring, and the height that utilizes ball to float drives pump working, makes liquid level reach normal level; Yet ball float level controller accuracy degree when the control liquid level is not high; And ball float is fragile, at some working environments that needs accurate control liquid level, then can't use.
The utility model content
The utility model technical matters to be solved is to realize the high water level controller of a kind of degree of accuracy.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of fluid level controller; Comprise fixed block and vertically pass several probes of fixed block that the length that every described probe stretches out fixed block differs the input circuit of described probe cut-in relay; The transformer input circuit is inserted in its output terminal loop, and the transformer output loop inserts water pump control circuit.
Described fixed block and probe stationary thereof are in stationary pipes, and described stationary pipes bottom is provided with through hole.
Described probe is provided with three, stretches out the longest probe of fixed block through compound transistor cut-in relay input circuit one end, in addition two probes cut-in relay input circuit other end optionally.
The advantage of the utility model is that fluid level controller is simple in structure, and cost of manufacture is low, is convenient to penetration and promotion, and controller response is high, and failure rate is low, and reliability is high, can be widely used in the supporting installation of new water pump and the transformation of old water pump.
Description of drawings
Face the content of every width of cloth accompanying drawing expression in the utility model instructions and the mark among the figure down and make brief description:
Fig. 1 is the fluid level controller structural representation;
Fig. 2 is the fluid level controller circuit structure diagram;
Mark among the above-mentioned figure is: 1, probe; 2, through hole; 3, fixed block; 4, stationary pipes.
Embodiment
Can know that referring to Fig. 1 fluid level controller is provided with several probes 1, every probe 1 vertically is fixed in the fixed block 3; Probe 1 is elongated tinsel, and fixed block 3 does not contact conducting each other for insulator guarantees probe 1, is fixed on that probe 1 on the fixed block 3 is parallel to each other and the length of stretching out fixed block 3 differs; Fixed block 3 is fixed in the stationary pipes 4; Be provided with in the bottom of stationary pipes 4 and be used for the through hole 2 that better is communicated with water tank, the circuit structure of fluid level controller is simple, the input circuit of its probe 1 cut-in relay; The transformer input circuit is inserted in the output terminal loop of relay, and the transformer output loop inserts water pump control circuit.
Here be that example is bright specifically with the water level controller that is provided with three probes 1; Stretch out the longest probe 1 of fixed block 3 through compound transistor BG1 and triode BG2 cut-in relay input circuit one end; Two probes 1 cut-in relay input circuit other end optionally in addition; These two probes 1 can optionally insert, the height that control water level keeps, thereby control pump working.After system's energising; Behind the longest water level probe 1 contact water surface, after the probe 1 of place in circuit touches the water surface, relay conducting adhesive; Drive pump working; After the short probe 1 of decline of water table left liquid level, pump process of compound transistor dead electricity and release relay finished, and system gets into holding state.
When new water pump is installed, connect a 20A A.C. contactor in this device relay installation site, can be to the easily control of operation automatically of the following submersible pump safety of 3KV; Only need break off former water level control line access device to old water pump gets final product; The water pump bigger to power only need be destroyed former water level control line, inserts this device and incorporates 1 relay of merely hitting in the relay installation site into, controls its main A.C. contactor line bag, do not do any change in the switch box, just can make this equipment implementation technological transformation.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
