Problems solved by technology

[0002] With the rapid development of industrial automation, the use of pneumatic and hydraulic products is also expanding, and the demand for products with gas and liquid sealing requirements is increasing, such as gas appliances, refrigerators, air conditioners, electronic components, cylinders, valves, Engines, liquid pumps, etc., accurately, efficiently and quantitatively test the gas and liquid sealing performance of products, which is an essential means for product manufacturers to ensure product quality, reduce production costs and even establish corporate image; the application number is CN200410072880 and a An air-tight leak detector that automatically calculates pressurization, balance, control and exhaust, which includes a pressure source, a pressure adjustment part, a differential pressure detection part, a standard joint, a probe and a control part, the pressure adjustment part has a pressure sensor, and the differential pressure The pressure detection section includes a balance valve, a ball valve, and a differential pressure sensor. The pressure sensor and the differential pressure sensor are connected to the control section through a circuit; the application number is 93247830, which also discloses a blast furnace cooling water leak detector. The leak detector can detect leaks manually or automatically, but it can only detect one state. For example, the airtight leak detector cannot detect the leakage of liquid, and vice versa. In addition, due to the long-term detection of the leak detector, there will be water vapor remaining inside the instrument. Residues such as dust and dust, especially the residues in the differential pressure sensor affect the accuracy of detection, and water vapor also causes damage to internal valves. With the use of multi-field technology for gas and liquid leak detection equipment, the Equipment and configuration requirements for leak detection are getting higher and higher
