Abstract

The invention provides a liquid pipeline emptying anti-freezing device. A water injection and drainage electromagnetic valve is arranged at the upper end of a water pipe, a drainage electromagnetic valve is arranged at the lower end of the water pipe, a water supply electromagnetic valve is arranged on the water pipe between the drainage electromagnetic valve and the water injection and drainage electromagnetic valve through a tap water pipe, and a drainage nozzle is arranged on the water pipe. The water injection and drainage electromagnetic valve and the drainage electromagnetic valve are controlled through a drainage electric switch and a water injection electric switch. Because the water injection and drainage electromagnetic valve and the drainage electromagnetic valve are arranged at the upper end and the lower end of the water pipe respectively, an emptying pipe can be communicated with a drainage pipe by the actions of the electromagnetic valves, accumulated water in the waterpipe is drained, and the water pipe is prevented from being frozen. The device has the characteristics of simple structure, reliable operation, convenience, practicability and convenience for control. The device is suitable to be installed in a solar water heater or other device for injecting and draining anti-freezing liquid.

Description

Technical field [0001] The invention proposes a device in the field of automatic control, specifically a liquid pipeline emptying antifreeze device. Background technique [0002] Before the present invention was proposed, taking solar water heaters as an example, the problem of anti-freezing water pipes was solved by winding an electric heating belt on the pipeline connected to the water storage device installed on the roof of the building. The disadvantage is that it wastes electric energy and is also easy to cause safety accidents such as fire and leakage. Another way to prevent the water pipe from freezing is to manually open the vent valve on the upper water pipe to release the water in the water pipe, so as to avoid freezing and blocking the water pipe and causing the water pipe to be frozen. The disadvantage is that when the water pipe needs to be emptied, people need to go up to a high place. One is not safe, and the other is cumbersome and inconvenient to operate. Summa...
