BUTTERFLY VALVE LIFE TEST EQUIPMENT

摘要

PURPOSE: A cross-section fixing lifetime testing device of a butterfly valve is provided to directly confirm the existence of a water leakage in outside after a test or in the middle of the test without disassembling a pipe and equipment joined to the valve when testing the lifetime of the valve by confirming the water leakage. CONSTITUTION: A cross-section fixing lifetime testing device (100) of a butterfly valve (10) comprises an inlet unit (20) and an inspection unit (30). The inlet unit is fixed on one surface of the valve. The inlet unit applies water pressure. The inspection unit is installed on the other surface of the valve. The inspection unit makes the discrimination of a water leakage in the valve in outside possible. [Reference numerals] (AA) Water pressure; (BB) Leaked fluid
