Automatic leakage detecting device of water heater or wall-hung stove and operating method thereof

Abstract

Provided are an automatic leakage detecting device of a water heater or a wall-hung stove and an operating method thereof.The automatic leakage detecting device of the water heater or the wall-hung stove comprises the water heater, wherein a ball valve, a filter, a pressure regulating valve, a first waterway pressure switching valve, a second waterway pressure switching valve and a pressure transmitter are sequentially arranged on a water inlet pipe of the water heater, and a water outlet valve is arranged on a water outlet pipe of the water heater.A pipeline between the pressure regulating valve and the first waterway pressure switching valve is communicated with a water-draining pressure-relief pipe, a pressure gauge is arranged at the communication position, and a pressure-relief valve and a pressure relief and regulation valve are sequentially arranged on the water-draining pressure-relief pipe.A pipeline between the first waterway pressure switching valve and the second waterway pressure switching valve is communicated with a servo pressurizing mechanism.The pressure transmitter is connected with a PLC.An electric actuator is arranged on the ball valve, the pressure regulating valve, the first waterway pressure switching valve, the second waterway pressure switching valve, the water outlet valve, the pressure relief and regulation valve and the pressure-relief valve respectively.The automatic leakage detecting device can achieve automatic detection and full-automatically judge the qualified or unqualified situation and has the advantages of being accurate in testing and good in reliability.

Description

technical field [0001] The invention relates to an automatic leakage detection device for a water heater or a wall-hung boiler and an operation method thereof. Background technique [0002] When a traditional water heater or wall-hung boiler is leak tested, the usual method is to first open the water inlet of the water pipe of the water heater or wall-hung boiler, then close the water outlet of the water pipe, and finally apply high pressure to the water pipe. During this process, the test Personnel only observe with the naked eye and judge whether there is a leak in the water pipe of the water heater or wall-hung boiler. Therefore, the accuracy of the judgment results obtained only by the naked eye observation of the test personnel is relatively low, and it is easy to misjudge, and sometimes even if there are slight cracks in the water pipes that cause slight leakage, it cannot be judged, especially in the case of water heaters. As a result, it was misjudged as a qualified...

Problems solved by technology

Therefore, the accuracy of the judgment results obtained only by the naked eye observation of the test personnel is relatively low, and it is easy to misjudge, and sometimes even if there are slight cracks in the water pipes that cause slight leakage, it cannot be judged, especially in the case of water heaters. As a result, it was misjudged as a qualified product and flowed out of the market, which finally had a certain impact on the quality of the water heater.
