Water-saving liquid level control method of solar water tank overflow pipe

Abstract

A solar water tank overflow pipe water-saving liquid level control method, which includes a solar water tank and an overflow leather pipe, an inclined overflow pipe is fixed on the side wall near the top of the water tank, and the bottom edge of the high port of the inclined overflow pipe is overflow The overflow port is slightly higher than the top wall of the water tank. The overflow leather pipe is connected to the end of the overflow pipe through an elbow and connected to the user's home. The user's home is equipped with a normally open micro-motion water valve to control the tap water inlet; the micro-motion water valve Automatic water cut-off is to use the surge along the wall generated when the nozzle of the inner water pipe is below the liquid level of the water tank, so that a small amount of surge water flows downward through the overflow outlet into the overflow leather pipe and then enters the water receiving cup that can be controlled to close the micro-motion water valve. , so that the normally open micro-motion water valve button is pressed down to close the valve under the weight of the water cup, and the water level of the water tank after the valve is closed is lower than the overflow port. In this way, the low-pressure water tank commonly used now is improved into a new method that can realize automatic control of the water intake of the low-pressure water tank and save water energy and heat energy by manually observing the overflow closing valve mode of the low-pressure water tank.

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
