Title:
手動用ダイヤフラムバルブ
Document Type and Number:
Japanese Patent JP7448368
Kind Code:
B2
Abstract:
A manually-operated diaphragm valve in which the open/close range of a valve disk can be set while compactness is maintained with a simple structure, and a sufficient flow rate at the time of full open is ensured. A valve main body (1) includes a valve disk (12) attached inside a body (10) and a spindle (13) screw-fastened to the body so as to be able to ascend and descend to cause the valve disk to make contact with and go away from a valve seat (14). A handle for manually performing rotating operation of the spindle is mounted above the valve main body. A full-open position adjustment mechanism (20) which limits rotation of the handle on a valve-opening operation side at full open and sets an upper limit of a flow rate when the valve disk is fully open is provided near an upper portion of the valve main body.
