Embodiment 1

[0024] See Figure 1-6 , the present invention is made up of water pipeline pipe, bottom plate 11, nozzle 9, pressure plate 2, top plate 3, four nozzle installation holes 17 are opened on the bottom plate 11, nozzle 9 is housed on the nozzle installation hole 17, and pressure plate 2 is arranged above the bottom plate 11, The pressure plate 2 is provided with a cylinder pressure hole 18 corresponding to the nozzle 9 and a slide bar penetration hole 19 corresponding to the slide bar 1. A top plate 3 is arranged above the pressure plate 2, and the top plate 3 is fixed by four columns 6 with nuts 5. Connected to the water tank 8 or the bottom plate 11, the middle part of the top plate 3 is fixedly equipped with an oil cylinder 4, the oil cylinder 4 is connected to the pressure plate 2, a slide bar 1 is provided between the bottom plate 11 and the top plate 3, and the pressure plate 2 can move along the slide bar 1 under the drive of the oil cylinder 4. Moving up and down, the wa...

Embodiment 2

[0031] In this embodiment, air is used to replace the water in Embodiment 1 to fill the cylinder body 21 of the gas cylinder to detect its airtightness. The structure and working process of the detection device are the same as those described in Embodiment 1.

[0032] The invention has the advantages that the airtightness of the gas cylinder can be detected when the gas cylinder has only the body structure, and the leaking gas cylinder body can be detected in advance, so as to avoid the waste caused by subsequent processing of waste parts, reduce the cost and improve the productivity. Moreover, it can detect gas cylinder barrels of different calibers and airtight products similar to the structure of the gas cylinder barrel, and only need to replace the corresponding pressure plate and nozzle module.

Abstract

The invention relates to a gas cylinder body airtightness detection device, and belongs to the field of measuring devices. The gas cylinder body airtightness detection device is provided with at least one gas way pipeline pipe or water way pipeline pipe, a bottom plate, a pressing plate, spraying nozzles and a top plate. The gas cylinder body airtightness detection device is characterized in that the bottom plate is provided with at least one spraying nozzle mounting hole, the pressing plate is arranged above the bottom plate, the pressing plate is provided with air cylinder pressing holes corresponding to the spraying nozzles, and the pressing plate is connected with the top plate through an oil cylinder; a gas cylinder body is buckled to the spraying nozzles in an inverted mode, the pressing plate is driven by the oil cylinder to press the bottom of the cylinder body so that the cylinder body can be clamped between the spraying nozzles and the pressing plate, it is guaranteed that a cylinder body opening is sealed, water or air is pumped into the cylinder body through spraying nozzle inner holes, a certain pressure is kept for a period of time, and whether the bottom of the cylinder body leaks the air or water is observed. By means of the gas cylinder body airtightness detection device, the airtightness of the gas cylinder body can be measured directly, the cylinder body which leaks the air can be detected in advance, waste caused by subsequent machining of waste pieces is avoided, the cost is reduced, and production efficiency is improved; the parts which can be detected by the gas cylinder body airtightness detection device are not restricted to the gas cylinder body, and all the products of the structure similar to that of the gas cylinder body can be detected.

Description

technical field [0001] The invention relates to a device for detecting air tightness of a cylinder body of a gas cylinder, which belongs to the field of testing devices. Background technique [0002] Fire bottle is one of the important industries in the fire protection industry in all countries in the world, and it is also one of the indispensable products in the fire protection industry of various countries. For the production of fire bottles, the production process of most enterprises in my country is to divide the gas cylinder into three parts: the cylinder body, the upper head, and the valve seat, which are processed separately and then welded and assembled to complete the production of the gas cylinder. For the air tightness test of gas cylinders, the existing device can only test the air tightness of the gas cylinders after the gas cylinders are completely produced. And materials cause waste, reduce the production efficiency of enterprises, and increase production co...
