Abstract:

 Aiming at the problem that the sealing ring of triple-offset butterfly valve needs to be re-fitted due to the processing errors during manufacture, the calculation formula for the matching ring of triple-offset butterfly valve is proposed. The possible reasons for the valve failure are analyzed. The working conditions under which the sealing ring needs to be re-fitted are analyzed, and the corresponding calculation formula is obtained. It is verified through calculation examples and field applications. The results show that the calculation formula for the matching ring of triple-offset butterfly valve is accurate, reliable and feasible.

Key words: triple-offset butterfly valve, butterfly sealing ring, production and processing, matching, calculation
