Liquid replenishing tank of solar system

Abstract

The invention provides a liquid replenishing tank of a solar system, and belongs to the technical field of solar water heating systems. By the aid of the liquid replenishing tank, technical problems of short service lives and the like of existing liquid replenishing tanks of solar systems can be solved. The liquid replenishing tank of the solar system comprises a tank. A single cavity is arranged in the tank, a liquid flowing opening is formed in the bottom of the tank, a support is fixed onto the tank and is positioned at the liquid flowing opening, a liquid flowing pipe is connected onto the support, one end of the liquid flowing pipe extends into the inner cavity of the tank, the other end of the liquid flowing pipe is positioned outside the tank, a pressure valve is connected with the end, which is positioned in the inner cavity, of the liquid flowing pipe, the liquid flowing pipe can be blocked or opened by the pressure valve, and balance between pressures of liquid in the liquid flowing pipe and pressures of liquid in the inner cavity of the tank can be kept by the pressure valve. The liquid replenishing tank has the advantage that the service life of the liquid replenishing tank can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of solar water heating systems, and relates to a liquid replenishing tank of a solar system. Background technique [0002] With the increasing population of the world and the depletion of energy, traditional energy has been difficult to meet people's living needs, so people pay more and more attention to the utilization of new energy, such as the utilization of solar energy. [0003] The solar water heating system is a device that uses solar collectors to collect solar radiation to heat water. It is a product with the most economic value, the most mature technology, and commercialization in the application and development of solar thermal energy. A solar water heating system generally includes a collector, an insulated water tank, an intelligent controller, and a liquid pipeline. In the liquid pipeline, due to the rise of water temperature, expansion will occur. Therefore, in order to absorb the part of the...

AI Technical Summary

Problems solved by technology

Although the expansion tank can ensure the pressure balance of the solar water heating system, it has the following disadvantages: First, the storage volume of the expansion tank is limited. The tank is easy to burst due to excessive pressure, which greatly affects the service life of the expansion tank

In addition, the airbag of the traditional expansion tank is made of elastic rubber material. Due to the limitation of the material of the airbag, its service life is limited, which also leads to the short service life of the expansion tank.
