Abstract
The utility model discloses a water supply controller for a water tank composed of a diverter, a rectification circuit, an electric relay, an electromagnetic valve, a water pump and a water tank. The input terminal of the electric relay is connected with a power cord and the output terminal of the electric relay is connected with the electromagnetic valve and the water pump. The control circuit of the electric relay is connected with the rectification circuit connected with the diverter. Two points of the diverter are respectively connected with the control point of the water level of the water tank. The utility model has the advantages of simple structure, low cost, long service life and reliable operation. When the water supply controller for a water tank works and the water level is lower than A1, the electric relay is connected the electricity, the electromagnetic valve drives the water pump to work, and the water is supplied for the water tank. When the water level reaches A2, the electric relay is unconnected with the electricity and the water pump stops working. When the water level falls below A2 above A1, the electric relay hasn't any motion.
Description
Technical field:
The utility model relates to water controller on a kind of residential building aqueous humor case.
Technical background:
All be equipped with water tank on the residential building roof at present, the last water management of water tank all is to adopt float switch control.Float switch the maloperation problem occurs through regular meeting, promptly can not start exactly or disconnect water pump, and serviceable life is short, generally uses and will be out of order in 3 months.
Summary of the invention:
The purpose of this utility model is: provide a kind of simple in structure, highly sensitive, safe in utilization, reliable, the water tank water-feeding controller that the life-span is long is to address the above problem.
The utility model is to constitute like this: it is by shunt resistance (1), rectification circuit (2), and relay (3), solenoid valve (4), water pump (5), water tank (6) is formed, and the input end of relay (3) connects power lead L
1, its output terminal connects solenoid valve (4) and water pump (5); The control circuit of relay (3) is connected with rectification circuit (2), and rectification circuit (2) connects shunt resistance (1), 2 water level reference mark A that connect water tank (6) respectively of shunt resistance (1)
1, A
2
Between shunt resistance (1) and rectification circuit (2), also be connected with transformer (7).
The utility model compared with prior art has simple in structurely, and cost is low, long service life, advantages such as reliable operation.During work, when water level is lower than A
1The time, relay power, the solenoid valve action makes pump working begin to go up water; Water level rises to A
2During point, the relay outage, water pump quits work; When decline of water table arrives A
2Following A
1When above, relay is failure to actuate.
