Zusammenfassung: | Disclosed is an overall air-tightness testing instrument, comprising a pneumatic control system, a regulating valve, a testing mechanism, an electric control system and an automatic plugging actuating mechanism. The pneumatic control system is connected to the testing mechanism through the regulating valve, and the electric control system is connected with the pneumatic control system, the regulating valve, the testing mechanism and the automatic plugging actuating mechanism so as to work in coordination. The pneumatic control system is composed of an air supply triple piece, a pressure reducing valve, a pressure gauge and a regulating valve, which are connected in sequence, and is used to provide compressed gas whose pressure is precisely controlled for the testing mechanism. The electric control system is composed of a mainboard, and a sensor, a communication port, a drive circuit and a control panel, which are arranged on the mainboard. The sensor is connected with the testing mechanism and is connected wi |
