Abstract

The invention provides a water-saving anti-freezing apparatus for solar heater pipe, comprising a water tank, an upper and a lower water pipe and a gas injection pipe. The apparatus is characterized in that a U-shaped bent pipe is provide in the apparatus, having the top portion thereof communicating with the lower end of an air injection uni-direction valve; one end of the U-shaped bent pipe extends to the bottom of the water tank, and the other end communicates with the upper end of a water supply and drainage pipe; the lower end of the water supply and drainage pipe communicates with a cross joint having other ends communicating with a water inlet valve, a water outlet valve and the lower end of a air pumping uni-direction valve; the upper end of the air pumping uni-direction valve communicates with an air extraction cylinder; one end of the air injection pipe communicates with the upper end of the air injection uni-direction valve, and the other end communicates with the control valve. Applying the structure, the water-saving anti-freezing apparatus is capable of discharging residual water in the water pipe, preventing freezing of the water pipe and operation failure due to scale, has extremely evident water-saving effect, consequently the apparatus is especially suitable for application on solar water heater in highly cold and highly water hardness region.

Description

technical field [0001] The invention relates to a water pipe control device, in particular to a water-saving antifreeze device for solar water heater pipes. Background technique [0002] In recent years, with social progress and continuous economic development, people's living standards have been greatly improved, families' awareness of energy conservation has become stronger and stronger, and solar water heaters have also been rapidly popularized. After the traditional solar water heater is used, there is residual water in the downpipe. Although the pipe is equipped with an insulation sleeve, a lot of cold water needs to be discharged when the water heater is used again in the cold winter, resulting in a serious waste of water resources; In some areas, sewer pipes are often blocked by freezing, which brings a lot of inconvenience to people's daily life. At present, there are also solar water heaters that use a solenoid valve to cooperate with the vent pipe to empty the rem...
