Embodiment Construction
[0025] The waterway detection method of the wall-hung boiler of the present invention comprises the following steps:
[0026] A. Install one piece of board-replacement integrated waterway, and block the heating return water inlet c and heating return water outlet d;
[0027] B. According to the water pump head, determine the water pressure value on both sides of the three-way valve sealing end, the operating pressure and full opening pressure of the bypass valve, the maximum water leakage at each operating pressure, and the maximum water leakage at each full opening pressure;
[0028] C. Drive the movement of the three-way valve to control the connection between the water inlet a and the heating return water outlet d;
[0029] D. According to the water pressure value on both sides of the sealing end of the three-way valve set in step A, input the water flow of a specific pressure into the water inlet a, observe the heating water outlet b, if there is water flowing out of the h...

The invention discloses a wall-hanging stove water channel detection method and device. According to the invention, water flow with specific pressure is delivered to a water inlet of an integrated water channel to be detected, plugs on a heat supply water outlet or a heat supply return water inlet and a heat supply return water outlet are blocked, the water inlet is enabled to be communicated with the heat supply water outlet or each heat supply return water outlet by using a three-way valve, a flow value at the corresponding state is measured, and thus whether a bypass and the three-way valve are qualified or not is quickly detected and judged, so that outgoing quality control for product is strengthened, and an overtemperature fault caused by opening the bypass in advance or not opening the bypass and a problem of circulating water communication caused by untight sealing of the three-way valve in the market are solved. The wall-hanging stove channel detection method and device are simple in structure and high in practicability, can ensure vulnerable components such as a one-way valve and a three-way valve in the integrated water channel to be qualified before delivery, improves the wall-hanging stove product safety and the user experience, and effectively prevents occurrence of problems such as unreasonable over temperature and heat supply water communication in products.
Description
technical field [0001] The invention relates to the detection technology of a gas-fired heating water heater, in particular to a waterway detection method and device for a wall-hung boiler. Background technique [0002] Gas wall-hung boilers use natural gas, artificial gas or liquefied gas as fuel. The fuel is output by the burner, and after burning in the combustion chamber, the heat is absorbed by the heat exchanger. When the circulating water in the heating system passes through the heat exchanger, it passes through the reciprocating Heating, thereby continuously outputting heat to the building, provides a heat source for the building. In addition to the heating function, the general dual-purpose gas wall-hung boiler also has the function of hot water. The wall-hung boiler can provide the heat source for the radiator and the floor heating system. Commonly used wall-hung boilers are divided into single-floor heating type and dual-purpose heating and bathing type, and the...
