Description
一、Overview:
The emergency shut-off valve calibration device independently developed by Jinan Bonor Technology Co., Ltd. is designed to test the shut-off performance of emergency shut-off valves under excessive flow conditions, meanwhile the tightness test can be carried out synchronously.
The overflow test bench for emergency shut-off valves is applied to verify whether the flow rate before the floating disc of emergency shut-off valve closes exceeds the value specified by relevant standards. This equipment is mainly supplied to manufacturers and inspection institutions of emergency shut-off valves for liquid tank trucks. It is applicable to factory tests and periodic inspections for the overflow protection function of emergency shut-off valves on liquefied tank trucks. Equipped with an automatic data acquisition module, the system can collect test data automatically and generate formal test reports.
