DISC EXCHANGE TYPE BUTTERFLY VALVE

摘要

A disc exchange-type butterfly valve is provided to separate only a driving shaft combined with a disc from a butterfly valve through an opening of a valve, thereby exchanging the disc in no need of exchanging the whole valve and facilitating an assembly for exchanging the disc. A disc exchange-type butterfly valve comprises a main body of a valve, a driving shaft(20), a lid(30) and a disc. Fluid flows inside the main body of the valve which is penetrated from a right side to a left side. The driving shaft is perpendicularly installed between an axis supporting unit(11) and an opening(12) of the valve. The lid opens or closes the opening. The disc mounted in the driving shaft opens or closes a flow channel of the valve.
