Double-pipe wall-hung stove water circuit system and operating control method thereof

Abstract

The invention relates to a double-pipe wall-hung stove water circuit system and an operating control method thereof. The double-pipe wall-hung stove water circuit system comprises a water outlet valve, a double-pipe heat exchanger, a heating water return pipe, a heating water outlet pipe, a bathing water inlet pipe, a bathing water outlet pipe, a bypass pipe and a water pump, wherein the water outlet valve comprises a valve body and a valve element, and the valve element is arranged in the valve body; and a water inlet, a first water outlet and a second water outlet are formed in the valve body, the first water outlet communicates with the heating water return pipe through the bypass pipe, the water inlet communicates with the heating water outlet pipe, and the valve element is used for controlling the first water outlet, the second water outlet and the water inlet to communicate or not communicate. According to the water circuit system and the operating control method thereof, the temperature of bathing water is stable and comfortable in the bathing mode, and the service life of the double-pipe heat exchanger is long.

Description

technical field [0001] The invention relates to the technical field of gas-fired heating water heaters, in particular to a casing-type wall-hung boiler waterway system and an operation control method thereof. Background technique [0002] In the traditional casing gas heating wall-hung boiler, after the bathroom function is stopped, the high-temperature water remaining in the bathroom pipe in the heat exchanger cannot be cooled in time, and the bathroom function is activated again in a short time, and the flame directly affects the residual high-temperature water in the bathroom pipe. The water is heated, causing the temperature of the water in the bathroom to be too high, causing the human skin to feel uncomfortable. In addition, the pipe wall of the heating pipe in the sleeve-pipe heat exchanger is prone to fouling, resulting in quality problems such as blockage of the heating pipe or cracking of the heating pipe, and shortening the service life of the sleeve-pipe heat exc...

[0002] In the traditional casing gas heating wall-hung boiler, after the bathroom function is stopped, the high-temperature water remaining in the bathroom pipe in the heat exchanger cannot be cooled in time, and the bathroom function is activated again in a short time, and the flame directly affects the residual high-temperature water in the bathroom pipe. The water is heated, causing the temperature of the bathroom water to be too high, causing the human skin to feel uncomfortable

In addition, the wall of the heating pipe in the sleeve-pipe heat exchanger is prone to fouling, which leads to quality problems such as blockage of the heating pipe or cracking of the heating pipe, and shortens the service life of the sleeve-pipe heat exchanger.
