Abstract
A water-locking self-control device for water pump comprises a shell with a water inlet and a water outlet, a film of a containing cavity in the shell between the water inlet and the outlet and a spring pressing device which is pressed tightly on the film. The water outlet is provided with a piston which is provided with a magnet, a dry reed pipe is arranged at the corresponding position to the magnet and is connected with a controlling circuit, when the water pool or well is short of water, the water flowing is reduced, and the water pump can stop working by the function of the circuit. The utility model has the advantages of accurate controlling, simple installation and wide use range without installing attachment under water.
Description
Technical field
The utility model relates to pump part, particularly a kind of electronic auto-control device of water pump.
Background technique
Water pump is when draining, and the water in pond or well is taken out to the greatest extent, and water pump idle running is not only wasted electric energy, and made water pump pump chamber lack of water, needs water filling again, troublesome poeration when reusing.A kind of water level controller appears recently, utilize ball float perception water level, as Chinese patent 99236731.X disclosed " full-automatic water level controller ", be in the ball float of sealing steel ball, switch to be set, switch is drawn by electric wire, and one end of electric wire is fixed on the pool wall during use, when ball float rises or descend, ball float and horizontal angle of inclination change, and steel ball makes switch motion because action of gravity is slided, and realizes opening or closing.This device need be fixed on an end of electric wire on the pool wall, can't install in some wells, has limited use; In addition owing to influenced by the mounting point, be difficult for accurately being controlled at water and just take out and water pump is quit work when most.
Summary of the invention
The utility model purpose is to provide a kind of water pump lack of water automatic control device by water flow control, with the raising precise control, and makes its installation simple, applied widely.
Scheme of the present utility model is: this device comprises a housing with water intake and water outlet, be arranged on the diaphragm in the cavity volume between the intake-outlet in the housing and be pressed on spring attachment on the diaphragm, piston is set in the water outlet, piston is provided with magnet, be provided with the magnetic control element with the magnet opposite position, the magnetic control element is connected with control circuit.
The utility model has the advantages that: owing in the water outlet piston is set, in the pond or during the well lack of water, water flow reduces, and current reduce the thrust of piston, and piston falls after rise, and magnet is near the magnetic control element, to its effect, and by control circuit water pump is quit work.Advantage with precise control, and do not need installation accessories under water, install simple, applied widely.
Description of drawings
The utility model is described in further detail with embodiment with reference to the accompanying drawings below.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model circuit theory diagrams.
1 housing among Fig. 1,2 diaphragms, 3 pistons, 4 water outlets, 5 magnet, 6 control circuit boards, 7 plugs, 8 safety check, 9 water intakes, 10 spring attachments; K wherein
1It is magnetic control element corresponding to magnet 5.
Embodiment
As shown in Figure 1, this device comprises a housing 1 with water intake 9 and water outlet 4, be arranged on the diaphragm 2 in the cavity volume between the intake-outlet in the housing 1 and be pressed on spring attachment 10 on the diaphragm 2, piston 3 is set in the water outlet 4, piston 3 is provided with magnet 5, is provided with magnetic control element K with magnet 5 opposite positions
1, K
1Be connected with control circuit 6.The magnetic control element can adopt dry reed-pipe or Hall unit, and what present embodiment adopted is dry reed-pipe.
In addition, diaphragm 2 is provided with plug 7, is shaped on projection on the plug 7, and projection and piston 3 contact.
The port of water intake 9 inboards is provided with safety check 8.
When the well lack of water, water flow reduces, and current reduce the thrust of piston 3, and piston 3 falls after rise, and magnet 5 is near magnetic control element K
1Be dry reed-pipe, make its adhesive.
Among Fig. 2, V

3Conducting, the J adhesive, water pump is kept working state.
Referring to Fig. 1, when device starts, water-filling in the cavity volume between intake-outlet, pressure rises, and diaphragm 2 is backed down, and moves on the projection on the plug 7, contacts piston 3, forces it to move, and prevents that piston 3 from blocking, and improved functional reliability.
This device has utilized the impetus of current to piston 3, to magnetic control element K
1Act on, and then water pump is controlled, have the advantage of precise control, and do not need installation accessories under water, install simple, applied widely by circuit.
