Problems solved by technology

Cold and heat exchange may produce accumulated water. The lower the air temperature and the greater the temperature difference, the more accumulated water will be generated, and the drainage pipe will be frozen due to the accumulated water generated by the cold and heat exchange. Can not work normally
There are still many disadvantages in the emptying and use effect of the existing emptying valve, which cannot meet the use requirements well

Abstract

The invention discloses a diving valve which is good in emptying effect and more stable in use. The diving valve comprises a valve body, a valve body shell, a valve rod and a water supply and drainage pipeline, wherein the valve body shell is arranged on the valve body and matched with the valve body, and the valve rod and the water supply and drainage pipeline are arranged in the valve body shell. The middle portion of the valve body is evenly provided with a plurality of drainage ports and a plurality of connecting insertion blocks. A plurality of connecting insertion grooves matched with the connecting insertion blocks are formed in the lower end of the valve body shell. The upper end of the valve rod is arranged on a balancing weight and a lifting positioning disc through a screw. A plurality of positioning teeth are evenly arranged on the periphery of the lifting positioning disc. A round sealing base is arranged in the middle of the valve rod. A conical rubber sealing ring is arranged at the lower end of the round sealing base. A magnet and an iron core are arranged at the lower end of the valve rod. The upper end of the magnet and the upper end of the iron core are arranged in an iron core installation cavity in the lower end of the valve rod.

Description

technical field [0001] The invention relates to a solar water heater accessory, in particular to a diving valve used in the solar water heater. Background technique [0002] In the cold winter season, solar water heaters are used, especially in the cold regions of the north, and vent valves are used on the pipes of solar water heaters. The vent valves installed on solar water heaters can not only continuously absorb the heat of the water heater, but also continuously absorb We call this phenomenon cold and heat exchange. Cold and heat exchange may produce accumulated water. The lower the air temperature and the greater the temperature difference, the more accumulated water will be generated, and the drainage pipe will be frozen due to the accumulated water generated by the cold and heat exchange. Can not work normally. There are still many drawbacks in the emptying and use effect of the existing emptying valve, which cannot well meet the use requirements. Contents of the...
