Abstract
The utility model provides a water-feeding level controller for a water storage container, which is composed of a water valve and a water-feeding pipe, wherein the water valve adopts an electromagnetic valve, the opening and the closing of the water valve are controlled by an opening-closing control circuit, wherein the opening-closing control circuit is composed of an alternating current-direct current forcing switch, two transformers, a rectification circuit, a filter circuit and a water level signal circuit, wherein one transformer is connected with the electromagnetic valve, and the other transformer, the rectification circuit and the filter circuit provide direct current power supply for the water level signal circuit. The alternating current-direct current forcing switch is connected with alternating current power supply, the alternating current contact head of the alternating current-direct current forcing switch is connected with the primary poles of the two transformers, and the direct current self-locking coil of the alternating current-direct current forcing switch is connected with the output end of the water level signal circuit. The water level signal circuit is composed of two water level probes at the upper part of the container and a transistor circuit. The electromagnetic valve energizes by pressing the alternating current-direct current forcing switch, and a water-feeding waterway is communicated. When water achieves the given water level, the two water level probes form a short circuit, the output end of the water level signal circuit makes the direct current self-locking coil of the forcing switch energize and makes the alternating-current contact head break, the electromagnetic valve forms the power cut and the waterway breaks. The water-feeding level controller has the advantages of simple structure, safe and reliable control and no watch.
Description
Technical field
The utility model provides water water level controller on a kind of water container
Background technology
There are many facilities that water container is all arranged in the daily life, as the ater storage box of the water storage tank of solar water heater system, automatic flow watering device, place the water tank of top of building etc., all need to the water container filling up water before the use.At present, give the general upward water that adopts manually of water on these water containers, establish a gap at the water container top, draw an overflow pipe from gap, the outlet of overflow pipe is located at the place that the operator can see.Open water valve, add water by upper hose to water container, when water was full, water will flow out along overflow pipe from gap, and the people of last water turns off water valve after seeing the water of overflow pipe outflow, cuts off the water route, has just finished the work of last water.The shortcoming of doing like this is: one, need manually on duty; Two, wasted more water resource.In order to overcome these shortcomings, people have found out some ways again, be the way of machinery control mostly, as ball-cock assembly is installed in water tank, though can be when Shang Shui reaches the predetermined water level of water tank automatic shutoff, but because the ball-cock assembly long period of soaking is in water, serviceable life is not long, breaks down easily, when ball-cock assembly breaks down, water still can not reach the purpose of automatic shutoff when full, and causes the waste of water resource.
The utility model content
The purpose of this utility model is to provide water water level controller on a kind of water container, and this controller long service life, fault are few, the conserve water resource.
Water water level controller on the water container provided by the utility model, by water valve, upper hose is formed, be characterized in that water valve adopts solenoid valve F, the open and close of solenoid valve F are controlled by an ON-OFF control circuit, described ON-OFF control circuit is by alternating current-direct current force switch K1, transformer B1, B2, rectification circuit, filtering circuit and water level signal circuit constitute, the secondary coil of transformer B2 meets solenoid valve F, transformer B1, the rectification circuit that commutation diode D1-D4 constitutes, the filtering circuit that is made of resistance R 1 capacitor C 1 joins successively and forms the direct supply of water level signal circuit, alternating current-direct current force switch K1 connects the 220V AC power, it exchanges contact K1-1 and meets transformer B1, the primary coil of B2, its direct current self-locking coil K1-2 is connected between the output of the positive pole of direct supply and water level signal circuit, the water level signal circuit is by the water-level probe T1 that is contained in gap place, water container top, T2, positive-negative-positive triode BG1 and NPN type triode BG2 constitute, the base stage of the collector connecting transistor BG2 of triode BG1, the emitter of triode BG1 connects the collector of triode BG2, the emitter of triode BG1 also connects the positive pole of direct supply by diode D5, water-level probe T1 connects the base stage of positive-negative-positive triode BG1, and water-level probe T2 connects the negative pole of direct supply and the emitter of NPN type triode BG2.
The principle of work of water water level controller is as follows on the water container provided by the utility model: when needs to water container on during water, press the alternating current-direct current force switch K1 of water level controller, at this moment, it exchanges contact K1-1 adhesive, connected transformer B1, the 220V AC power of B2, the solenoid valve F that joins with B2 level of transformer gets, open, the water route conducting, water is by solenoid valve F, upper hose is a water on the water container, simultaneously, transformer B1, the rectification circuit that commutation diode D1-D4 constitutes, the filtering circuit that is made of resistance R 1 capacitor C 1 provides direct supply for the water level signal circuit, but in last water process, before water level does not reach preposition as yet, the base stage of triode BG1 is in high level in the water level signal circuit, the water level signal circuit is not worked, no signal output, and last water process continues.When the water container water level reaches preposition, the water-level probe T1, the T2 that are contained in gap place, water container top are by the water short circuit, become low level with the base stage of the triode BG1 that joins of probe T1, the water level signal circuit working that constitutes by triode BG1, BG2, triode BG1, BG2 conducting, the self-locking coil K1-2 that is connected on the alternating current-direct current force switch K1 of water level signal circuit output end gets, pressure disconnects the interchange contact K1-1 of alternating current-direct current force switch K1, transformer B1, B2 disconnect the 220V power supply, solenoid valve F dead electricity, the water route disconnects, and finishes water conservancy project and does.During water, repeat above-mentioned action again on next time.
Water water level controller on the water container provided by the utility model, when last water water level reached predetermined water level, the water water level controller can cut off the water route immediately automatically on this water container, and the conserve water resource has been stopped waste.It is simple in structure, cost of manufacture is low, control is safe, reliable, fault is few, need not be on duty, long service life.
