Summary
This device is a detection device for tank accessories (breathing valve, flame arrester, hydraulic safety valve), and is an operating platform for detecting whether tank accessories are qualified. This device can be used to detect accessories of storage tanks with diameters ranging from DN50 to DN250 and DN50 to DN350. The main parameters for detection include opening pressure, ventilation rate, operating pressure, and pressure difference.
