本供气阀原理:
Principle of This demand valve:
供气阀内设有大膜片自动平衡系统,大膜片自动跟踪人的呼吸动作,实现按需供气,并保证面罩内的压力高于周围环境压力。
There is big diaphragm valve inside as the self-balancing system, automatically tracking users’ breathing actions, provide the on-demand supply and ensure that pressure inside the mask higher than external environment.
供气阀前面方形手动关闭按钮,可关闭供气阀的输出气流,停止供气。吸气时由吸力自动开启。
The square manual turnoff button in front of demand valve can turn off the demand valve against the outputting air flow to stop air supply. And it will automatically starts by the suction at inhalation.
供气阀底部中心圆形的手动强制供气按钮,一是手动关闭按钮没被吸开时用手按压此按钮,可实现自动供气;二是佩戴者感到气体供给不足时,按下此按钮,供气阀会自动增大供气量。另外它可以放掉中压导管中的余气压力,方便检测和拆卸快速接头。
At the bottom is the manual force air supply button, it can automatically supply air when press this button if manual shut-off button fails, secondly, once users do not feel the air supply sufficient and touch this, air flow output will be increased automatically. In addition, it allows the outflux of some not-used-up air pressure in medium pressure hose thus to easily check and disassemble the quick connector.
