Method of mounting valve seats in a butterfly valve |
摘要 |
A method of mounting valve seats in a butterfly valve comprising a valve body mounted in a valve stem in a valve housing. The valve seats are attached to the valve housing so as to contact the periphery of the valve body when the valve is closed. End surfaces of the valve seats are adjusted relative to the valve stem and seal members by means of first bolts. Then, the first bolts are replaced with third bolts for pressing the valve seats against the periphery of the valve body.
