Summary of the invention
The object of the present invention is to provide one can detect gas cylinder stack shell waste product part ahead of time, avoid continuing to process waste product part, save operation, time and materials, the gas cylinder stack shell air-tightness detection device boosted productivity.
The technical scheme that technical matters solved by the invention adopts:
The present invention includes: at least one gas circuit or waterway tube deferent, base plate, pressing plate, nozzle, top board, it is characterized in that, base plate at least has a nozzle mounting hole, above base plate, be provided with pressing plate, pressing plate has the gas cylinder pressure hole corresponding with nozzle, pressing plate is connected with top board by oil cylinder.
Further: to be provided with slide bar between base plate and top board, pressing plate has slide bar and penetrate hole, pressing plate can be free to slide on slide bar.
Further: oil cylinder is fixed in the middle part of top board, and top board is fixedly connected with base plate by column.
Further: the inside surface in gas cylinder pressure hole be with gas cylinder bottom the curved surface that matches.
Further: nozzle is core structure, and nozzle outer surface is fixed with snap ring.
The invention has the beneficial effects as follows: gas cylinder stack shell is tipped upside down on nozzle, pressing plate compresses bottom gas cylinder stack shell by hydraulic oil cylinder driving, gas cylinder stack shell is made to be clamped between nozzle and pressing plate, ensure that gas cylinder stack shell mouth is sealed, water or air by nozzle bore by being pumped into gas cylinder stack shell, keep certain pressure a period of time, observe bottom gas cylinder stack shell and whether leak gas or drainage.
The present invention directly can measure the impermeability of gas cylinder stack shell, detects the gas cylinder stack shell of gas leakage ahead of time, avoids doing following process to waste product part and causes waste, reduce costs, boost productivity.
The present invention puts the measured piece that will detect and is not limited to this kind of product of gas cylinder stack shell, and the product being similar to this structure of gas cylinder stack shell all can detect.
