Full-automatic pressure bearing pressure-free operation system of heat storage water tank of water heater

Abstract

The invention relates to a full-automatic pressure bearing pressure-free operation system of a heat storage water tank of a water heater. The system comprises the heat storage water tank, and the outside of the heat storage water tank is connected with a cold water inlet channel and a hot water outlet channel. The system is characterized in that a normally closed solenoid valve is arranged on the cold water inlet channel; the hot water outlet channel is sequentially connected with a pressure relief pipeline in parallel, a one-way valve in series and a pressure switch in parallel in the water flowing direction; a normally opened solenoid valve is arranged on the pressure relief pipeline. The system has the beneficial effects that the interior of the heat storage water tank does not bear high pressure any more when water inside the heat storage water tank is not used; the explosion phenomenon of a tank-free solar vacuum pipe is effectively prevented; the phenomena of fatigue, corrosion and breakdown leaking of the heat storage water tank of the water storage type water heater are effectively solved; the pressure and water relief amount is reduced; the occurrence rate of flood is reduced; the frequency of electric leakage accidents is reduced; safety performance is improved.

Description

(1) Technical field [0001] The invention relates to a tankless solar energy, air energy, split wall-mounted solar energy, and a pressure control device for an electric water heater storage tank, in particular to a fully automatic pressure-bearing and pressure-free operating system for a water heater storage tank. (2) Background technology [0002] A solar water heater is a device that converts solar radiation energy into heat energy. In addition, water heaters can also be divided into air-energy water heaters, split wall-mounted solar water heaters, and electric water heaters. In addition to large-diameter vacuum heat collecting tube tankless solar water heaters, air energy, split wall-mounted solar energy, and electric water heaters are all inseparable from the hot water storage tank, and the hot water storage tank is a very important core component. Traditional hot water storage tanks are made of pressure-bearing metal liners at home and abroad, which are not corrosion-re...

AI Technical Summary

Problems solved by technology

Traditional hot water storage tanks are made of pressure-bearing metal liners at home and abroad, which are not corrosion-resistant and easy to break down. Under long-term high temperature and high pressure, fatigue, water leakage, shortened service life, poor electrical insulation performance, and water tank Once there is water leakage due to the effect of pressure, it will bring floods to people, affect the relationship between the upper and lower neighbors, and the vacuum tube solar water heater without water tank will burst due to excessive pressure or instability.
