Background technology
Fire fighting bottle is one of industry important in the fire protection industry of countries in the world, one of indispensable product in the middle of Ye Shi various countries fire-fighting cause.For the production of fire fighting bottle, the production technology of China's most enterprises is all that gas cylinder is divided into three parts: gas cylinder stack shell, upper cover, valve seat, carries out welding assembly respectively after processing, completes gas cylinder and produces.For the air-leakage test of gas cylinder, existing apparatus just can only can carry out air-leakage test to gas cylinder after the complete production of gas cylinder, now find that there is gas leak phenomenon and be then considered as waste product, but this causes waste to operation wherein and material, reduce the production efficiency of enterprise, add production cost.Because gas cylinder gas leakage often occurs in bottom gas cylinder stack shell, the present invention designs one and closes up bottom gas cylinder stack shell afterwards and before welding with upper cover, only gas cylinder stack shell carried out to the device of air-leakage test, find waste product in advance, avoid waste product to continue processing and cause waste, boost productivity.
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.

Embodiment
embodiment 1
See Fig. 1-6, the present invention is pipeline pipe by water, base plate 11, nozzle 9, pressing plate 2, top board 3 forms, base plate 11 has four nozzle mounting holes 17, nozzle 9 nozzle mounting hole 17 is equipped with, pressing plate 2 is provided with above base plate 11, pressing plate 2 having the gas cylinder corresponding with nozzle 9 presses hole 18 and the slide bar corresponding with slide bar 1 to penetrate hole 19, top board 3 is provided with above pressing plate 2, top board 3 is connected on water tank 8 or base plate 11 by four root posts 6 nut 5, oil cylinder 4 is installed with in the middle part of top board 3, oil cylinder 4 is connected with pressing plate 2, slide bar 1 is provided with between base plate 11 and top board 3, pressing plate 2 can move up and down along slide bar 1 under oil cylinder 4 drives, hydraulic pressure is connected with water source by waterway tube deferent.
Described waterway tube deferent is made up of isocon 14, diverting valve 13 and bend pipe 7.Described base plate 11 is fixed on water tank 8 top by screw 15.Described nozzle 9 is core structure, and nozzle 9 outside surface is fixed with snap ring 20, is fixed on base plate 11 by fastening spiro loop 12.The inside surface in described gas cylinder pressure hole 18 be with gas cylinder bottom the curved surface that matches.Described oil cylinder 4 oil cylinder pin 16 and oil cylinder piston pin 10 are fixed on top board 3 and pressing plate 2, to ensure that oil cylinder 4 pairs of pressing plates 2 are evenly exerted pressure.
Detailed testing process
During equipment use, gas cylinder stack shell 21 back-off is placed on nozzle 9, then oil circuit control makes oil cylinder 4 by exerting pressure bottom pressing plate 2 pairs of gas cylinder stack shells 21, horizontal lifting can be kept to make pressing plate 2, pressing plate 2 direction of motion is controlled by slide bar 1, the gas cylinder on pressing plate 2 is made to press the bottom close contact of hole 18 and gas cylinder stack shell 21, control water route simultaneously and carry out pressurization water-filling by waterway tube deferent and nozzle 9 pairs of gas cylinder stack shell 21 inside, water filling is stopped after reaching predetermined hydraulic pressure, and whether the bottom center of observing gas cylinder stack shell 21 has and leaks or the phenomenon of bubbling, the sealing property bottom gas cylinder stack shell 21 is judged with this, after detection completes, gas cylinder stack shell 21 decompression is discharged water, promote pressing plate 2, take out gas cylinder stack shell 21, detect complete.
