Title:
DIGITAL VALVE
Document Type and Number:
Japanese Patent JPH01299370
Kind Code:
A
Abstract:

PURPOSE: To easily remove a shutter module and to accurately add a flow rate while restricting the size of a valve by forming a bent pipe with the inlet and outlet walls of a valve seat and the shutter module and arranging a sealing means between the contact face of the module and the wall of the corresponding valve seat.

CONSTITUTION: A bent pipe, including an inlet branch 32 almost perpendicular to an inlet wall 14 and an outlet branch 34 almost perpendicular to an outlet wall 18 in order to pass fluid when a shutter 46 is open, is formed with the inlet wall 14 and the outlet wall 18 of a valve seat 10 and a corresponding shutter module 24 involving one of the shutters 46. A sealing means is arranged around the inlet and outlet branches 32, 34 between each of the contact faces 25, 27 of the module 24 and each of the walls 14, 18 of the corresponding valve seat. As a result, after the valve body 10 is unfixed from the shutter module 24, the module 24 can be radially and slantly removed. Even if a portion of a flow rate is greater than the valve 10, the accuracy of adding the flow rate is not affected.
