Diving emptying valve

Abstract

The invention discloses a diving emptying valve which does not have the frozen blocking phenomenon; the diving emptying valve comprises a valve seat and a valve body shell arranged on the valve seat, wherein the upper end of the valve body shell is provided with a vent pipe connecting hole; the valve body shell is internally provided with an upper guide gear sleeve and a lower guide gear sleeve; a coil is arranged in the valve body shell at the upper end of the upper guide gear sleeve; the upper guide gear sleeve is internally provided with the upper part of an iron valve mandrel; the upper part of the iron valve mandrel is connected with the middle part of the iron valve mandrel by a fixing bolt; the lower end of the middle part of the iron valve mandrel is connected with the lower part of the iron valve mandrel; a strong magnetic piece is arranged between the upper part of the iron valve mandrel and the lower part of the iron valve mandrel in the middle part of the iron valve mandrel; the lower part of the iron valve mandrel is internally provided with a channel; the lower part outer side of the lower part of the iron valve mandrel is provided with a hemispherical sealing rubber block; the valve seat is provided with a water supply and drain channel and a plurality of drain holes; and the lower end of the water supply and drain channel is provided with a water supply and drain pipe connecting hole.

Description

technical field [0001] The invention relates to an emptying valve, in particular to a diving emptying valve. 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. The emptying valve and the emptying pipeline will be frozen and blocked by the accumulated water generated by the cold and heat exchange. The emptying valve and the emptying pipeline will not work properly if they are frozen and blocked. The exhaust valve has been used in the solar industry for more than ten years. So ...

AI Technical Summary

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. The emptying valve and the emptying pipeline will be frozen due to the accumulated water generated by the cold and heat exchange. If the emptying valve and emptying pipe are frozen and blocked, they will not work normally

The exhaust valve has been used in the solar energy industry for more than ten years. So far, there has been no product that really solves the problem. The most important thing is that it cannot fundamentally solve the cold and heat exchange problem of the exhaust valve.
