Water supply control valve for solar water heater

Abstract

The invention discloses a solar water heater water supply control valve. The water supply control valve is a floating ball control valve provided with a floating ball chamber and a floating ball communicated with a solar water tank, comprising a valve body, a valve cover and an auxiliary cover; a valve The valve body is arranged above the valve cover, the auxiliary cover is arranged under the valve cover, and the valve body is sealed with the valve cover and the auxiliary cover. The invention adopts a floating ball control valve to control the water level in the water tank of the solar water heater. When the water level in the water tank is low, the water level in the floating ball room decreases, and the water inlet pipe in the water supply control valve is guided through the valve body outlet pipe and the auxiliary cover water outlet pipe. The water level in the floating ball chamber rises synchronously with the water level in the water tank. When the water level reaches a stable equilibrium water level, the water inlet pipe in the water supply control valve and the water outlet pipe of the valve body are disconnected, so that the water level in the water supply control valve is disconnected. The water tank is filled with water; the invention has the advantages of simple structure, fast water filling speed, convenient installation and maintenance, no need for power supply, energy saving and environmental protection, stable and reliable performance, and good popularization and application value.

Description

technical field [0001] The invention belongs to the field of solar water heaters, in particular to a water supply control valve for solar water heaters. Background technique [0002] Generally, most of the traditional domestic solar water heaters are not equipped with a water supply control valve. After the water is full, a large amount of water will overflow continuously, and the water inlet valve must be manually closed to cut off the water, which will cause a large amount of water resources. waste. Also have solar water heater to be provided with water level sensor and electromagnetic valve to control water level at present, its shortcoming is that must have power supply to work normally. In the event of a power failure, the water heater cannot be used or the water supply valve still needs to be manually turned on and off to maintain its work. In addition, the water level sensor and solenoid valve are complex in structure, easily damaged, unstable in operation, poor in r...

Problems solved by technology

[0002] Generally, most of the traditional domestic solar water heaters are not equipped with a water supply control valve. After the water is full, a large amount of water will overflow continuously, and the water inlet valve must be manually closed to cut off the water, which will cause a large amount of water resources. waste

At present, there are also solar water heaters equipped with water level sensors and solenoid valves to control the water level. The disadvantage is that they must have a power supply to work normally.

In the event of a power failure, the water heater cannot be used or the water supply valve still needs to be manually turned on and off to maintain its work. In addition, the water level sensor and solenoid valve have complex structures, are easily damaged, unstable in operation, poor in reliability, and slow in water supply speed.
