Hermetic sealing program control testing stand

Abstract

The invention discloses a hermetic sealing program control testing stand, comprising a working platform, a clamping positioning device, a sealing plugging device, a gas source processing device, a compression gauge and an electric control cabinet. The clamping positioning device comprises a pedestal, a clamping air cylinder and a position limiting block; the output terminal of the clamping air cylinder is provided with a clamping block; the sealing plugging device comprises two sealing plugging mechanisms which are identical in structures; each sealing plugging mechanism comprises a support base, a sealing plug and a sealing plugging air cylinder; the output terminal of the sealing plugging air cylinder is fixedly connected to an installation block which is fixedly connected to the sealing plug through a gas channel joint and the sealing plug; the air inlet terminal of a gas processing device is in communication with an air source; the air outlet terminal is in communication connection with the corresponding gas channel joint of the sealing plugging mechanism through a first switch solenoid valve; and the corresponding gas channel joint of another sealing plugging mechanism is in communication connection with the pressure gauge. The hermetic sealing program control testing stand is simple in structure, easy in operation, low in manufacture cost, high in testing accuracy and wide in application range, and does not affect the pipe fitting quality during the detection process.

Description

technical field [0001] The invention relates to the technical field of air-tightness detection devices, in particular to an air-tightness program-controlled test bench. Background technique [0002] Most of the pipe fittings need to be tested for air tightness after they are manufactured, so as to detect whether there are leakage points on the pipe wall of the pipe fittings. Existing methods for testing the airtightness of pipe fittings are generally through water pressure testing. The detection method is to seal both ends of the pipe fitting to be tested with a clamp, place it in water after pressurization, and determine whether the pipe body is leaking according to whether there are air bubbles in the pool. The defects of this hydraulic testing method are as follows: First, since the tube body needs to be put into water during testing, if the tube body is made of iron material, it is easy to cause the tube body to rust, which will affect the quality of the pipe fittings. ...

Problems solved by technology

The defects of this hydraulic testing method are as follows: First, since the tube body needs to be put into water during testing, if the tube body is made of iron material, it is easy to cause the tube body to rust, which will affect the quality of the pipe fittings. Second, it is usually necessary to dry the pipe fittings after testing, which makes operation and use more inconvenient; third, the test accuracy is low, and it is easy to miss micropores
