Title:
流体混合物
Document Type and Number:
Japanese Patent JP2010517744
Kind Code:
A
Abstract:
A gas mixing device feeds from two gas sources (1, 4), placing each gas into half of a chamber (17, 16) which is divided by a flexible physical barrier (12), such that pressure is equalised across the chambers (16, 17). Upon the release of each gas from each chamber at the same time into a mixing barrel (7), exit pressures and thus mixing characteristics are suitably controlled for a desired mix of gasses, due to the pressure balancing effect of the flexible barrier (12). The device might also be termed a divider or a dilutor. The device might be used in the mixing of low concentrations of carbon monoxide, such as 1 percent, in nitrogen with more nitrogen to dilute the concentration to 0.001 percent.
