Backward-flowing prevention system for pool or water tank

Abstract

The invention relates to a backward-flowing prevention system for a pool or a water tank. The backward-flowing prevention system comprises a pool water inlet main pipe, the tail end of a control pipe is connected with the pool water inlet main pipe, and the tail end of the pool water inlet main pipe is connected with a water inlet which is formed in one side of a water reservoir. An abnormal water level chamber is mounted on the right side of an abnormal water level judging chamber, and a baffle is mounted between the abnormal water level chamber and the abnormal water level judging chamber. The lower end of the abnormal water level judging chamber communicates with a sump through a water collecting guide pipe, and an adjusting valve is mounted in the middle of the water collecting guide pipe. According to a water cold-accumulation and direct-cold-supply backward-flowing prevention device and a using method thereof, a remote-control ball float valve is used for preventing freeze water from flowing back into the pool according to the water level in the water reservoir, when the water level in the water reservoir is higher than an overflowing water level and water in the pool flows to the sump through an overflowing pipe without control, the remote-control ball float valve is closed to limit water flow, and waste of water resources is avoided.

Description

technical field [0001] The invention relates to the technical field of anti-dumping, in particular to a tank or tank anti-dumping system. Background technique [0002] In the water storage air-conditioning project, the storage tanks (cold storage tanks, heat storage tanks) or water storage tanks (cold storage tanks, heat storage tanks) are divided into direct cooling supply mode and indirect cooling supply mode to the cold end. The direct cooling method means that the chilled water in the cold storage tank is directly in contact with the cooling equipment such as the terminal combined wind cabinet and fan coil; equipment, not in direct contact with cold equipment. Although the direct cooling method has many benefits, it has not been basically applied in water-cooled air-conditioning projects. The reason is that the direct cooling method has a high risk of backflow, that is, the chilled water of the air-conditioning system flows back to the reservoir for some reason (cooling...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of tank or tank anti-dumping system, to solve the previous anti-dumping technology proposed in the above-mentioned background technology is all realized by electrical control, reliability and stability are not good, and by floating The ball is used to control the water inflow. Sometimes the float ball will malfunction, get stuck or damaged, so that the water will continue to enter, causing water waste.
