<p>PURPOSE: To easily decompose and operate a seal part by containing a valve spindle in a seal cartridge which can be slipped into a valve hole and which can be taken out. CONSTITUTION: A seal cartridge 41 is slip-inserted into a valve hole 31 formed in a housing 10. This has seal rings 43-45 formed as an assembly to be engaged with the valve hole 31 in a sealed condition. A valve spindle 55 is assembled into the seal cartridge 41, and this is engaged with the seal rings 43-45 in the sealed condition. This is moved between a valve closed position and a valve opened position to control flows of fluid between inlets 32, 34, 35 and outlets 33, 36 of a housing 10. The seal cartridge 44 can be easily inserted into/pulled out of the valve hole 31 as a single unit.</p> |
