摘　　要：为了提高气瓶阀密封性能检测的精度和检测速度,设计了一种气瓶阀密封性一步检测装置,该装置克服了现有检测方法中检测步骤多、检测时间长、操作复杂、成本高、效率低的缺点。实验结果表明:将检测效率提高了近3倍,检测时间小于20 s。A cylinder valve was designed in order to improve the cylinder valve sealing performance detection accuracy and detection speed sealing step detection device, the device overcomes the existing detection methods in the detection step, long detection time, complex operation, high cost, the disadvantage of low efficiency. The experimental results show that the detection efficiency is increased by nearly three times, the detection time is less than 20 seconds.
