Abstract

PURPOSE: To remarkably reduce man-hours required for fabrication and assembly work and also production cost by forming at a stroke means to check the over-turn and coming-off of the valve-shaft against the valve seat.
CONSTITUTION: A net-pattern is indented by knurl work on irregular portions of the valve-shaft 1 jointing and contacting the valve-seat 3. The net-pattern comes in close contact with the contact surface of the valve-seat 3 formed by the injection of synthetic resin and play the part of checking the over-turn and coming-off at the same time. Further, on the periphery of the valve seat 3, an arbitrary number of projections 11 is created to check the over-turn when tightening the screw 9. The screw 9 has an objective to bind the diaphragm 13 and plate 14, 15 holding it, and when the screw 9 is tightened by using the nut 17, by performing the tightening operation inserting projections 11 to the indent of templets 16 to check the over- turn, projections 11 are sheared off if tightening is over thus preventing the excessive tightening.
