Online safety valve calibration station

I. Purpose of online calibration: According to the requirements of the “Guidelines for the Application of Safety Valves for Boilers in Power Stations” (DL / T959-2005), the setting pressure of the boiler safety valves shall be calibrated. Second, the principle of online verification The opening and closing actions of the spring safety valve rely on the change of the medium pressure at the inlet end and the spring pre-tension force to automatically open and close the valve core. When the medium pressure (internal pressure) rises ... Details >>>
