Gas flowmeter specifications
Suction system (passive) is divided into three major components; negative regulator part, the dirt collection part suction tube section.
Negative regulator part includes: Vacuum gauge, control valve, plug valve seepage, etc, which is the body part of inhaler, requires vacuum gauge indicates accurate, adjustable hand wheel adjustment freely, not micro-seepage drain valve.
Dirt collection part mainly includes: Security set liquid bottle, and anti-suck back device ,requirements: suction tubes are sealing, anti-suck back devices are sensitive and reliable.
Suction tube section includes suction tube and nozzle two accessories requirements: at -0.075MPa pressure does not suck dirt sucked inside deflated caused by the use of less safe drip Bottle;
Flowmeter main performance parameter
Suction system (passive) negative pressure in the atmosphere is not higher than 0.02Mpa (150mmHg), not less than 0.07Mpa (525mmHg), and can be adjusted within the range. In -0.07Mpa, the maximum liquid flow rate should be greater than 5 L / min;
When inhaled liquid to a safe drip bottle capacity of maximum calibrated set or liquid bottle filled with safety drip bottle ,float should seal the suction port and automatically stopping the suction to prevent the suction of the liquid is drawn into the negative pressure regulating valve and the negative pressure piping systems
Suction plug and medical gas outlet should good compatibility, easy handing, reliable locking, the medical gas outlet connections have no leakage under the pressure -0.07MPa.
Suction system(passive) which the rate average of leakage caused by pressurization must be less than 1.8% per hour.
the vacuum gauge accuracy2.5 range of suction system is 0~-0.1MPa.
