Device for realizing full-automatic emptying and pressurizing of solar water heater

Abstract

The invention belongs to the technical field of water heaters, and discloses a device for realizing full-automatic emptying and pressurizing of a solar water heater. The device comprises a main pipe,a connecting ring is fixedly welded to the left side of the lower end of the main pipe, a water pump is fixedly installed on the left side of the connecting ring, and a protective cover is fixedly installed on the surface of the connecting ring. A first control valve is fixedly installed at the lower end of the main pipe, a wall is fixedly installed on the left side of the lower end of the main pipe, a three-way pipe is fixedly installed in the middle of the main pipe, and a secondary pipe is fixedly installed on the right side of the three-way pipe. By arranging the main pipe, the secondary pipe, a second water tank and the like, the purpose of good emptying and pressurizing effects is achieved, when the water pressure in a water supply pipeline is insufficient, an operator starts the water pump to supplement water at the moment, the water pressure of an external pipeline is relatively large, so that the redundant supplied water directly moves into the second water tank, and water bodies are gradually increased.

Description

technical field [0001] The invention belongs to the technical field of water heaters, in particular to a device for realizing full-automatic emptying and pressurization of solar water heaters. Background technique [0002] Solar water heater is a heating device that converts sunlight energy into heat energy. It heats water from low temperature to high temperature to meet the needs of people in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. , mainly vacuum tube solar water heaters, occupying 95% of the domestic market share. The heat collecting tube utilizes the principle that hot water floats up and cold water sinks, so that the water generates microcirculation to obtain the required hot water. [0003] Existing solar water heaters often have insufficient water pressure when in use, especially for residents with higher floors. This situation is often more obvious in o...

Problems solved by technology

[0003] Existing solar water heaters often have insufficient water pressure when in use, especially for residents with higher floors. This situation is often more obvious in old residential areas, and insufficient water pressure will lead to water supply effects. Poor, when multiple pipelines use water at the same time, it is easy to have a water stop, so there is an urgent need for a device that realizes fully automatic emptying and boosting of solar water heaters
