Technical Field

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

The automatic control water adding method of the solar water tank is characterized in that an automatic water control valve or an electric contact type valve and the like which are placed beside the roof water tank are frequently used, the roof is repaired inconveniently, the repair rate is high, electric contacts produced by some manufacturers need to be replaced once in two years, circuit boards of some pressure-bearing type solar water tanks are frequently damaged, and one circuit board needs to be replaced by hundreds of yuan, so that the low-pressure solar water tank manually controlled by an overflow pipe is practical, the manual control method is that the overflow pipe of the water tank is connected to a water tank at home by a leather pipe, a user visually observes that water overflows into the water tank in the leather pipe, namely the valve is closed by hands, and the water inlet of the water. This has the advantage that the overflow tube is reliable and durable and does not need to be replaced as often. However, people have trouble observing, overflow is wasted by carelessness, the valve is closed even if the overflow is seen, the water level in the water tank is higher than the overflow port when the valve is closed, so that a large amount of overflow is lost from the overflow port, so that the overflow is always a half washbasin, and after the water in the water tank is heated by the sun, the water volume expands, and a few liters of hot water in the water tank overflows outwards from the overflow port of the overflow pipe, so that double waste of water and heat energy is caused.

Disclosure of Invention

The purpose of the invention is: the overflow pipe can reduce overflow water from flowing out after the water tank is filled with water, and the overflow water can be used to automatically close the water filling valve.

The solar water tank comprises a solar water tank, wherein an inclined overflow pipe is fixedly connected to the side wall of the water tank close to the top of the solar water tank, the lower end opening of the inclined overflow pipe is in a wedge shape, the wedge-shaped end opening is fixedly connected to a side wall hole of the water tank, the wedge-shaped cross section of the inclined overflow pipe and the side wall of the water tank are positioned on the same plane, the bottom edge of the high end opening of the inclined overflow pipe is an overflow opening, the overflow opening is slightly higher than the top wall of the water tank, the overflow opening and one end of an overflow elbow are fixedly connected into a whole, the other end of the overflow elbow is connected with an overflow leather pipe, the overflow leather pipe connected with a vent pipe is connected to the home of a user, the home of the user is provided with a normally open micro water valve for controlling tap; the valve body of the micro water valve is fixedly connected with a bracket, a rotating shaft is inserted in a shaft hole on the bracket, the rotating shaft is fixedly connected with one end of a pressing sheet, the bottom of the pressing sheet is positioned above the micro button, a water receiving cup capable of receiving overflowing water is arranged close to the other end of the pressing sheet, and the water receiving cup can be positioned by a shelf; when the fine motion water valve is normally open, the mouth of pipe of interior water pipe is intake in to the water tank behind the cold water inlet tube of fine motion water valve, water tank bottom and the interior water pipe of water tank, and the mouth of pipe of interior water pipe is in the low port below of water tank slope warning pipe, and the mouth of pipe direction of interior water pipe makes the mouth of pipe of interior water pipe go out water can directly spout into the warning mouth, characterized by: the automatic water cut-off of the micro water inlet valve is realized by utilizing the wall surging generated when the pipe orifice of the inner water pipe is positioned below the liquid level of the water tank, so that a small amount of surging water flows downwards into the overflow rubber pipe through the overflow port and then enters the water receiving cup arranged on the pressure applying sheet, and the bearing capacity of the water receiving cup reaches the threshold value for closing the normally open micro water valve, thereby realizing the valve closing.

Thus, the surge is terminated when the valve is closed, and the water level in the tank drops below the overflow. The working process is as follows: when water needs to be added, a user pours out the water in the water receiving cup, the normally open micro water valve feeds water to the solar water tank, a water column at the port of the inner water pipe is sprayed to the top end of the water tank, and downward splashing is formed; when water enters the water tank to enable the water level to exceed the pipe orifice of the inner water pipe, the water column at the pipe orifice is blocked by the water level, so that the columnar form of upward injection of the water column is changed, the water is diffused towards the periphery, the lower end of the inclined overflow pipe is in a wedge shape, the water entering area is large, and the inclined overflow pipe is smoothly connected with the pipe wall, so that diffused water waves can flow upwards along the pipe wall, so-called 'surging along the wall' is generated, the principle of huge waves generated when sea waves beat on the coast is the same, at the moment, the water level is lower than the overflow port, but part of surging water still reaches the overflow port through the inclined overflow pipe and enters the overflow leather pipe, the overflowed water flows to a water receiving cup arranged on a pressure applying piece of a micro-motion water inlet valve of a user through the overflow leather pipe, and the average water level of the. The inching water valve is sensitive, so that the inching valve can be closed when the water quantity in the water receiving cup reaches more than 50 grams, the water tank stops water inlet after the inching water valve is closed, and the water surface is stopped at a position lower than the overflow port; the water level is higher than the position of the overflow port when the valve is closed manually, and then the water flows out of the overflow port through siphoning or advection, so that the water loss is high when the valve is closed manually. The use of the vent pipe can make the surge smoother. When the water inflow stops, the surging along the wall stops, and the water level without the surging is much lower than the surging, so when the inflow water is thermally expanded by the solar irradiation, the water level does not exceed the overflow port even if rising, and the hot water can not be lost. When the water tank needs to be opened again after water is used, the water in the water receiving cup is poured out, and the process can be repeated. In summary, the method can realize the automatic control of the water inlet of the low-pressure water tank and save water energy and heat energy.
