Abstract
PURPOSE:To prevent leakage and improve durability and reliability by transmitting an operating force applied to a valve stem push-in screw to a valve stem push-in rod via a valve stem push-in spring, and closely attaching a valve body to a valve seat with a defined force. CONSTITUTION:A valve stem 5' is linked to a valve stem push-in rod 7' through a hole 20 in the center of a diaphragm 6'. A valve stem pull-up spring receiver 30 is connected to the top end part of the valve stem push-in rod 7' and a valve stem push-in spring 24 is provided with pressure between the two. A valve stem pull-up spring 29 is provided with pressure between the valve stem pull-up spring receiver 30 and a bonnet 27. The end of a valve stem push-in screw 31 which is screwed into a case body 21 is brought into contact with the top face of the valve stem pull-up spring receiver 30. When the valve stem push-in screw 31 is moved downward by means of a lever 32, the valve stem push-in rod 7' and the valve stem 5' are depressed via the valve stem push-in spring 24, causing a valve body to be closely attached to a valve seat with a define force.
