The invention discloses a
respirator detector. The
respirator detector comprises a to-be-tested
respirator air
bottle, a high-
pressure sensor, a first
cut-off valve, to-be-tested respirator
pressure reduction valve, a medium-
pressure sensor, a second
cut-off valve, a to-be-tested respirator adjusting device, an
artificial lung and a low-
pressure sensor wherein one end of the high-pressure sensor is connected with the to-be-tested respirator air
bottle, the other end is connected with a
signal receiving end, one end of the first
cut-off valve is connected with the to-be-tested respirator air
bottle, the to-be-tested respirator
pressure reduction valve is connected with the first cut-off valve, one end of the medium-pressure sensor is connected with the respirator
pressure reduction valve, the other end is connected with a
signal receiving end, the second cut-off valve is connected with the to-be-tested respirator pressure reduction valve, the to-be-tested respirator adjusting device isconnected with the second cut-off valve, the
artificial lung is connected with the respirator adjusting device, one end of the low-pressure sensor is connected with the
artificial lung, and the otherend is connected with a
signal receiving end. The invention further provides a detecting method of the respirator
detector, and the airtightness of a whole device, the outlet pressure of the respirator pressure reduction valve, the
respiration resistance of a respirator adjusting device and flow rate detection can be detected in one attempt.
