Overview of breathing valve detector
< 2.
Breathing valve detector is a precision instrument specially used to calibrate various types of breathing valves. The instrument has the characteristics of small size and light weight. The breathing valve detector is easy to assemble and unload. It has a wide application range and can be calibrated and approved for all types of breathing valves from D to D. It has the characteristics of verifying the exhalation and inhalation opening pressure of the breathing valve on site.

< 3. Working principle of the breathing valve detector
< The breathing valve detector consists of a vacuum pump, an air pump and a test platform. Use the vacuum pump to obtain negative pressure to detect the inhalation opening pressure of the breathing valve. Use the air pump to obtain positive pressure to detect the exhalation opening pressure of the breathing valve to detect whether the inhalation and exhalation pressure values of the breathing valve meet the standards (current national standard/-standard ) to determine whether the breathing valve is qualified.
< 4. Operating Instructions for Breathing Valve Detector
< Install the breathing valve and use an Allen wrench to tighten the fastening bolts between the breathing valve and the work surface
< Plug in the power supply (,)
< Breathing valve test: Determine the operating pressure according to the model and grade of the breathing valve being tested (see table).
