Abstract

PURPOSE: To miniaturize a valve and make its installation feasible by mounting a bypass valve of ball shaped structure on the valve body of a main butterfly valve.
CONSTITUTION: When the main valve 2 is opened, if bypass valve 5 is rotated by 90 degrees, the bypass valve 5 is opened and water upstream of the main valve 2 passes through the flow passage 7 of bypass valve 5, gradually running into the downstream side of main valve 2. Then water is filled in a vortex-type casing at the downstream side, eliminating a pressure difference between the both sides of the main valve 2. Due to the installation of bypass valve 5 on the main valve 2, separate piping for the bypass valve is no longer required and space for equipment arrangement is minimized. In addition, pipe rack for the bypass valve is dispensed with, thus enabling the compact designing of the valve system.
