Problems solved by technology

[0004] The biggest defect of this kind of water tank water level automatic controller is that: when the water tank enters the water and the power is cut off and then on again, the contact S 2 and relay K 0 All have been released and disconnected and cannot restore the water to the water tank, so that the application in the solar water heater will cause the water tank to not be filled with water, the water in the water tank is small, and the hot water obtained is also insufficient to supply, and the solar energy cannot be fully and effectively utilized. Solar water heaters are energy-saving and environmentally friendly; and when the water in the water tank is cut off and the water is short of water, the motor is still energized and idling, which wastes electric energy and the motor cannot be protected.
Both the direct reed switch type and the electrode probe type automatic water level controller have a water level signal transmission line between the water tank and the indoor controller, which is difficult to install and maintain, and the cost is high, and the control circuit needs long-term uninterrupted power supply. energy saving effect

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] figure 1 The circuit principle diagram of the water tank water level controller in the prior art shown has been described in the previous background technology, and will not be repeated here.

[0018] exist figure 2 As shown in the schematic diagram of the system structure of the present invention, the system includes: a water source 1, a one-way valve 2, an upper water pipe 3, an electric water pump 4, a water shortage signal valve 5, a pneumatic water level gauge 6, a water supply pipe 7 and a water tank 8. Wherein, a part of the upper water pipe 3 is also used as a water supply and lower water pipe, and the check valve 2 is located at the lower end or front end of the upper water pipe 3 inserted into the underwater part of the water source 1; It communicates with the upper water pipe 3; the water shortage signal valve 5, as framed by the dotted line, is ...

Abstract

The automatic controller comprises control circuit applied with pulse relay: water shortage signal value having magnetic floating ball and dry-reed tube as the two cooperated to each other for outputting signal of water supply, water off and water shortage, air-pressure type of water level meter having magnetic floating mark and regulation bar in cylindrical shape cavity to pick up water level signal for water box as some other place as the magnetic floating mark cooperated with the dry-reed tube to pick up signal of high and low water level in water box. The circuit cooperating with water shortage signal valve and water level meter can be used for water supply and water off protection as well as water level automatic control for the water box.

Description

technical field [0001] The invention relates to a liquid level controller, in particular to an automatic water level controller for a water tank of a water supply system. Background technique [0002] There are many kinds of automatic controllers for the water level of the water tank in the water supply system. Some use the magnetic floating ball directly installed in the water tank to cooperate with the reed switch to detect the water level (referred to as the direct reed switch type); some use the electrode probe installed in the water tank. To detect the water level (referred to as the electrode probe type); some use the pressure change of the water to detect the water level. [0003] Among them, the more commonly used figure 1 The shown float pressure control switch water tank water level automatic controller is recorded in Chapter 9 of Volume 6 of "New Encyclopedia of Electronic Circuits" published by China Metrology Press in January 2001. Its working principle is: wh...
