Water-saving type liquid surface control method for overflow pipe of solar water tank

Abstract

A water-saving type liquid surface control method for an overflow pipe of a solar water tank involves the solar water tank and the overflow leather pipe. The inclined overflow pipe is fixedly connected with the side wall, close to the top, of the water tank. The bottom side of the high port of the inclined overflow pipe is provided with an overflow hole, and the overflow hole is slightly higher than the top wall of the water tank. The overflow leather pipe is connected to one end of the overflow pipe through an elbow and connected into a user home. A normally-open inching water valve for controlling the inlet of tap water is arranged in the user home. For the automatic water stopping of the inching water valve, through the surge along wall generated when a pipe opening of an inner water pipe is located below the liquid surface of the water tank, a small amount of surge water downwards flows into the overflow leather pipe through the overflow hole and then enters a water receiving cup capable of controlling the inching water valve to be switched off, the water receiving cup bears loads to press down a button of the normally-open inching water valve and switch off the water valve, and the liquid surface of the water tank is lower than the overflow hole after the valve is switched off. Thus, an existing common method of manually observing the water overflow and switching off a valve for a low-pressure water tank is improved into the new method of automatically controlling the water inlet of the low-pressure water tank and also saving water energy and heat energy.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a water-saving liquid level control method for an overflow pipe of a solar water tank. Background technique [0002] The solar water tank automatically controls the method of adding water. There are often automatic water control valves or electric contact valves placed on the side of the roof water tank. However, repairs on the roof are troublesome, and the repair rate is relatively high. The electric contacts produced by some manufacturers need to be replaced every two years. Once, the circuit boards of some pressurized solar water tanks are often damaged, and it costs several hundred yuan to replace a circuit board. Therefore, it is more practical to manually control the low-pressure solar water tanks with overflow pipes. The leather tube is connected to the water tank in the user's home, and the user visually observes that water in the leather tube overflows into the wa...

Problems solved by technology

However, it is very troublesome for people to observe, and if they are not careful, the overflow will be wasted. Even if the valve is closed when the overflow is seen, the water level in the water tank is higher than the overflow when the valve is closed, so a large amount of overflow must be lost from the overflow. The overflow water is half a washbasin, and when the sun heats the water in the water tank, the volume of the water expands, and several liters of hot water in the water tank will overflow from the overflow of the overflow pipe, resulting in double waste of water and heat energy
