Two-way control water supply device

Abstract

The invention provides a two-way control water supply device supplying water to water storage tanks of high-rise buildings. The two-way control water supply device consists of a water pump, a solenoid valve, an alternating current stabilized voltage power circuit, and two water supply control circuits with the same circuit structure which are connected with the output of the alternating current stabilized voltage power circuit, which are parallelly connected with a 220V alternating current; and each of the two water supply control circuits consists of a rectifier bridge, a water-level gauge, a capacitor, a relay, and two electrodes positioned at a warning water level of a water storage tank. When two water storage tanks are required to be supplied with water, an alternating current power source of the water pump and the solenoid valve and the two water supply control circuits are connected, and the two electrodes positioned at the warning water level are conducted in water when water in one of the water storage tanks reaches the warning water level; meanwhile, the rectifier bridge works to output a direct current to charge the capacitor, and when the capacitor is filled, a coil ofthe relay parallelly connected with the capacitor is electrified, and a normally-closed contact of the relay is released to cut off the alternating current circuit of the water pump or the solenoid valve to stop supplying water. The two-way control water supply device can simultaneously controls to supply water to the two water storage tanks, and has sensitive control and stable work.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and relates to a dual-way control water heater for water supply to a water storage container. technical background [0002] Water supply in high-rise buildings at present often needs to use water pump or electromagnetic valve to send water to the water storage container or the storage pool of the roof of the building, and then send to each high-rise resident; The roof of the building also needs a water pump or solenoid valve to send water to the water storage container on the roof of the building. But because the water storage container or the water storage tank is installed on the roof of the building, so often after the water is full and overflows the water storage container, the sound of running water will be heard to close the water pump or the electromagnetic valve to stop the water supply, resulting in waste of water. When the solenoid valve supplies water, if something happens, ...

Problems solved by technology

But because the water storage container or the water storage tank is installed on the roof of the building, so often after the water is full and overflows the water storage container, the sound of running water will be heard to close the water pump or the electromagnetic valve to stop the water supply, resulting in waste of water. When the solenoid valve supplies water, if there is something to leave, it will cause greater losses

In order to avoid the waste of water, there are also some water feeders that can control the water supply level at present. These water feeders can cut off the water supply when the water level of the water storage container reaches a certain position, but their shortcomings are: one, the control is not sensitive enough, and two. , It can only control the water supply to one water storage container, but cannot control the water supply to two water storage containers
