船舱内气体采样法简称CQ采样法,它是基于传统的气体采样技术,以玻璃注射器为动力设备、以全玻双磨口活塞三通为单向气流控制器,与采气管、连接管、样品容器共同组成气体采集系统。该法解决了舱内气样的采集问题,并具有如下特点:(1)杜绝了采样者自身受害事故发生,(2)根除了由于采样动力不防爆而带来的燃煤隐患,(3)广泛适用于采样者无法直接进入的舱、罐、窖、池、沟、井内等处的气样采集。
Cabin gas sampling method referred to as CQ sampling method, which is based on the traditional gas sampling technology to glass syringe as the power equipment to all-glass double-grinding mouth three-way piston air flow controller, and the gas pipe, connecting pipe, sample Containers together form a gas collection system. The method solves the problem of gas sample collection in the cabin and has the following characteristics: (1) to prevent the accident of the victim from being sampled, (2) to eliminate the coal-burning potential caused by the sampling power not being explosion-proof, and (3) Widely used in sampler who can not directly enter the cabin, tank, pit, pool, ditch, wells and other gas samples collected at.
