Aerostat valve air tightness detection system and detection method

Abstract

The embodiment of the invention relates to the technical field of aerostats, and provides an aerostat valve air tightness detection system and detection method. The detection system comprises a gas supply device, a test tank, and a gas volume measurement device. A valve to be tested is installed in the test tank to divide the interior of the test tank into a high-pressure cavity and a low-pressurecavity. The high-pressure cavity is provided with a first air inlet, and the air supply device is communicated with the first air inlet. The air supply device is used for supplying air to the high-pressure cavity and keeping the high-pressure cavity in a constant pressure state. The low-pressure cavity is provided with an air outlet, and the gas volume measuring device is communicated with the air outlet. According to the aerostat valve air tightness detection system provided by the embodiment of the invention, the detection of the air tightness of an aerostat valve is realized, and the gas leakage amount of the aerostat valve in a specific pressure environment can be quantitatively and accurately measured.

Description

technical field [0001] The invention relates to the technical field of aerostats, in particular to an aerostat valve airtightness detection system and detection method. Background technique [0002] An aerostat is a lighter-than-air aircraft based on a balloon or airship. A balloon is an unpowered aircraft, usually divided into high-altitude balloons and tethered balloons according to its structure and whether it has a mooring device; an airship is an aerostat with a propulsion device that can independently provide forward power . The aerostat has the characteristics of long dwell time, high ceiling, strong fixed-point ability, stable and quiet flight, and strong load capacity. It has become the preferred platform in many specific fields and plays an important role in scientific research, military and economic development. [0003] The main structure of the aerostat includes capsule, pod, empennage and so on. The capsule of the aerostat contains a main airbag and a second...
