Abstract

The invention discloses a leakage check device for metal hoses in batch, which is used for solving the problems of high labor intensity and low testing efficiency existing in leakage check of the metal hoses. The leakage check device consists of a control part, an air channel part, an elevating water groove and a hose supporting and locking mechanism, wherein the elevating water groove is positioned on the lower part of the hose locking mechanism; the lower part of the elevating groove is provided with an elevating frame; and the control part is electrically connected with the air channel part, the hose supporting and locking mechanism and the elevating frame. Matched pressure testing parts are selected according to different metal hose specifications, so that pressure test is performed in batch. The metal hose locking mechanism in the device is designed according to the structural characteristics of joint positions at the two ends of each metal hose, so that the metal hose can be clamped or detached rapidly and conveniently; and in a testing process, the pressure is controlled by using a computer, data are recorded according to a testing result, and unqualified products are automatically distinguished according to visual observation and a pressure value fed back by using a pressure sensor. The leakage check device has the advantages of high automatic degree, greatly-improved production efficiency and accurate and reliable detection result.

Description

technical field [0001] The invention relates to a detection device, in particular to a batch leak test device for metal hoses, and belongs to the detection technical field. Background technique [0002] Metal hoses are important connecting components in engineering technology. They consist of metal bellows, mesh sleeves and joints to form a metal hose assembly. They are suitable for air, steam, various industrial gases, and various fluids such as water, oil, and medicine. In transportation and other piping systems with large displacement and high operating frequency, it plays an important role in the reciprocating motion of the piping system, thermal expansion absorption, vibration absorption, and piping center adjustment. The metal hose needs to be checked for air leakage before assembly. At present, the air leakage test of the metal hose includes: 1. Wind pressure test, place the metal hose assembly in the water tank, slowly pass air at a certain pressure, and keep the pre...
