Description
Technical field
The present invention relates to bellows air tightness detection equipment technical field, specifically a kind of intelligent bellows is airtight
Property batch detecting device and detection method.
Background technology
Corrugated stainless steel tubing is installed on as a kind of flexible pressure-resistant pipe fitting in liquid conveying system, to compensate pipeline or machine
The effects that mutual displacement of device, equipment connecting pin absorbs vibrational energy, can play vibration damping, noise reduction has flexible, quality
The multinomial feature such as gently, corrosion-resistant, antifatigue, high-low temperature resistant.But the use of existing bellows will generally form both ends and be welded with method
Blue modular construction, gas or liquid medium of the ripple tube cavity filled with certain pressure when use, such as combustion gas inflammable gas, because
This, it is necessary to assure its leakproofness, it is ensured that its security performance.
The existing bellows method of inspection is generally detected by hydraulic pressure, and detection means is close for that will detect bellows both ends to be measured
Envelope, is positioned in water after pressurization, according to there is bubble-free, to judge whether tube body leaks；
The detection means major defect mainly has the following
1) bubble-free needs artificial judgement, so there is the case where erroneous judgement, misjudgement；
2) water itself has stainless steel certain corrosiveness, influences product quality；
3) when detecting, product sealing needs manual operation, and needs double cooperation, is manually respectively screwed into seal plug
Both ends pipe fitting, daily 8 hours, amount of inspection about 500 or so needed to use 0.5 cubic metre of water daily, and working efficiency is low,
Improve testing cost；
4) it after product testing, needs to dry, drying acc power is 10KW, needs continuous baking 3 hours, daily power consumption daily
30KWH increases production cost, reduces production efficiency.
Through retrieval, Chinese utility model patent：CN201120509395.X discloses a kind of effective gas tightness inspection of ripple
Device, including air leakage detector are surveyed, it further includes the detection core bar being arranged in bellows to be measured and is arranged in wave to be measured
Line pipe both ends, and the detection fixture of corrugated tube end to be measured is sealed, detection fixture is equipped with the sealing for pressing closer corrugated tube end to be measured
Plugging, sealing plugging are connected by tracheae with air leakage detector.Utility model carries out air pressure detection using gas is filled with
The leakproofness of bellows, machine judgement is more reasonable, avoids causing leaker to be judged by accident because of human factor；Meanwhile avoid tube body with
Water contacts, and improves product appearance quality, has saved water consumption；Every bellows is detected as single detection, pneumostop substitution
Manual seal, greatly reduces labor intensity, and production efficiency improves 50% or more, eliminates baking operation, energy is greatly saved
Source.
But it still has more serious disadvantage, such as operating procedure is still cumbersome, needs first to insert detection core bar
Enter into bellows to be detected, the both ends of bellows to be detected are then passed through into jointing and assembly detection apparatus respectively
Connection, the bellows for needing dismounting to detect after detection, then repeats the above process.In this detection mode, once
It is merely able to detection one, detection efficiency is low, still to be improved.
