消防瓶是世界各国消防产业中重要的产业之一,也是各国消防事业当中不可缺少的产品之一。对于消防瓶的生产,我国大多数企业的生产工艺都是将气瓶分成三部分:气瓶筒身、上封头、阀座,分别加工后进行焊接组装,完成气瓶生产。对于气瓶的气密性检测,现有装置只能在气瓶完整生产后才可对气瓶进行气密性检测,此时发现有漏气现象则视为废品,但这已经对其中的工序和材料造成了浪费,降低企业的生产效率,增加了生产成本。由于气瓶漏气往往发生在气瓶筒身底部,本发明设计一种在气瓶筒身底部收口后且与上封头焊接之前,只对气瓶筒身进行气密性检测的装置,提前查出废品,避免废品继续加工造成浪费,提高生产率。 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 costs. Since gas cylinder leakage often occurs at the bottom of the gas cylinder body, this invention designs a device that only performs air tightness testing on the gas cylinder body after the bottom of the gas cylinder body is closed and before welding with the upper head. Detect waste products, avoid waste caused by continuous processing of waste products, and improve productivity.

详细检测工作过程 Detailed inspection work process

设备使用时将气瓶筒身21倒扣安置在喷嘴9上,然后控制油路使油缸4通过压板2对气瓶筒身21底部施压,为了使压板2能够保持水平升降,通过滑杆1控制压板2运动方向,使压板2上的气瓶压孔18与气瓶筒身21的底部紧密接触,同时控制水路通过水路管道管和喷嘴9对气瓶筒身21内部进行加压充水,达到预定的水压后停止注水,并观察气瓶筒身21的底部中央是否有漏水或冒泡的现象,以此来判断气瓶筒身21底部的密封性能,检测完成后对气瓶筒身21减压放水,提升压板2,取出气瓶筒身21,检测完毕。 When the equipment is in use, place the cylinder body 21 upside down on the nozzle 9, and then control the oil circuit so that the oil cylinder 4 exerts pressure on the bottom of the cylinder body 21 through the pressure plate 2. Control the movement direction of the pressure plate 2 so that the cylinder pressure hole 18 on the pressure plate 2 is in close contact with the bottom of the cylinder body 21, and at the same time control the water channel to pressurize and fill the inside of the cylinder body 21 through the water pipe and nozzle 9, Stop water injection after reaching the predetermined water pressure, and observe whether there is water leakage or bubbling in the center of the bottom of the gas cylinder body 21, so as to judge the sealing performance of the bottom of the gas cylinder body 21, and check the gas cylinder body after the inspection is completed. 21 depressurize and release water, lift the pressing plate 2, take out the cylinder body 21 of the gas cylinder, and the detection is completed.

In this state, the cylinder body 21 of the gas cylinder that has been detected last time is taken out, and the next gas cylinder body 21 to be detected is placed.

图8为本发明施压过程中的加压状态图。在此状态下,压板2给气瓶筒身21施加一定的工作压力,同时,控制水路通过喷嘴9向气瓶筒身21加压充水,保持一定时间。 Fig. 8 is a diagram of the pressurization state during the pressurization process of the present invention. In this state, the pressure plate 2 applies a certain working pressure to the gas cylinder body 21, and at the same time, the control water channel pressurizes and fills the gas cylinder body 21 through the nozzle 9 for a certain period of time.

实施例2Example 2

    本实施例中用空气代替实施例1中的水充入气瓶筒身21,检测其气密性,检测装置结构和工作过程与实例1中所述相同。 In this embodiment, air is used instead of water in Embodiment 1 to fill the cylinder body 21 of the gas cylinder, and its airtightness is tested.
