Abstract
The utility model relates to a multipurpose automatic controller for liquid level, comprising a liquid level sensor and an automatic control circuit. The liquid level sensor comprises a tension spring, a slide block, a slide track, a magnet block, a dry reed pipe and a float ball. The automatic control circuit comprises a power circuit, a main control circuit, a sink control circuit and a well control circuit. The utility model has the advantages of simple structure, stable performance, strong reliability, low cost, convenient application, etc.
Description
The utility model relates to controller, particularly a kind of automatic control of liquid devices of using more.
Present commercially available various automatic control of liquid devices and automatic water pump, its sampling detector generally is to adopt aluminium electric wire or stainless steel metal to make electrode, because electrode is under water throughout the year, be easy to tie dirt or get rusty, its conductive resistance is increased, cause self-actuated controller out of control, poor stability, and complex structure, the cost height.
The purpose of this utility model provides a kind of simple in structure, stable performance, good reliability, the multipurpose liquid self-actuated controller that cost is low.
Technical solution scheme of the present utility model is: the sampled signal of controller is to utilize the buoyancy in the ball float controlling liquid of two high low-water level poor, and take out by magnetic switch.Liquid sensor is to utilize extension spring stretch along with the buoyancy of water level float size, when driving slide plate and arriving or leave high low-water level control line, makes the conducting of closing or opening pilot relay of magnetic patch and tongue tube or disconnection and finishes the automatic process of controlling of liquid.
The sampled signal of this automatic control of liquid device is not by water or other liquid, be not subjected to the influence of sample line length, liquid sensor adopts enclosed parts, its long term operation stability and good reliability, the liquid level range of control can be selected arbitrarily and regulate, and is simple in structure, easy to maintenance, applied widely, except doing automatic suction, water supply and water level control, still can make automatic, the semiautomatic control usefulness of liquid of water and non-water substance.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a liquid sensor structural drawing of the present utility model.
Fig. 2 is an automatic control circuit schematic diagram of the present utility model.
In liquid sensor shown in Figure 1, one end of spring (1) is fixed on the box body with screw (5), the other end is connected with slide plate (2), slide plate (2) center fixed has magnetic patch (3), ball float (9) is connected with slide plate (2), size by slide plate (2) in the box body (7) has slide rail (4), and tongue tube (6), G2 are fixed in the chute (8).The tongue tube G1 of control low water level sensor is installed in below the slide block (2), and the tongue tube G2 of high water level sensor is installed in above the slide block (2).The sensor extension line a of high low-water level, b, c are connected with automatic control circuit a, b, c point.
In automatic control circuit schematic diagram shown in Figure 2, formed by power circuit, governor circuit, water (tower) pond control circuit, well control circuit.The 220V voltage of power circuit gets the 12V supply control circuit by transformer T step-down after the D1-D4 bridge rectifier passes through capacitor C 1 filtering.The resistance R 1 of well control circuit is connected in series with relay J 1, normally opened contact J1-1 in the parallel circuit of back, and hand push button N1 also meets J1-1.The current-limiting resistance R2 of water (tower) pond control circuit, in relay J 2, the normally opened contact J2-1 serial connection back parallel circuit, button N2 also meets J2-1.Another group normally opened contact J1-2, the J2-2 of relay J 1, J2 are connected in series with relay J 3 in the parallel circuit of back, and pull-up resistor R3 is connected in series back J3 in parallel with light emitting diode D5, and relay J 3 is connected with motor.
The utility model principle of work is such, when the ball float in pond drops to low-water line, magnetic patch (2) is connected tongue tube (7), J2-1 gets electric adhesive self-locking simultaneously, J2-2, J3 conducting machine operation are drawn water, and when water arrived high-water line, magnetic patch (2) was connected tongue tube G2, relay J 2 discharges, and J3 disconnects motor and quits work.If in the time of must taking out the water in full water pond temporarily, can press button N2, then J2-1 gets electric adhesive self-locking, and J3 conducting machine operation is drawn water, and when water arrived high-water line, J2 discharged, and J3 disconnects motor and quits work.The principle of work of control well also is the same.
According to above-mentioned design concept, utilize this liquid sensor external circuits can make various any selections and liquid level automatic display adjusting, multipoint mode and liquid level autoalarm.
Claims (2)
1, a kind of use the automatic control of liquid device more, formed, it is characterized in that by liquid level sensor, automatic control circuit:
