Abstract

PURPOSE:To prevent sticking and accumulation of dust onto a fixed sheet in the case when a valve piece is in the opened state, by allowing the captioned damper to be interlocked with the opening and closing operation of the valve piece and permitting a protective cover for the fixed sheet to be operated through a link mechanism. CONSTITUTION:In the state where a valve piece 4 is pressed onto an annular fixed sheet 1 arranged at the duct opening edge part and cuts-off the flow of liquid, a protective cover 2 is at the retreat position from the fixed sheet 1. If a cylinder device 5 is driven to extend a piston rod in this state, a turning shaft 6 is turned, and the valve piece 4 is opened, and also a turning shaft 7 is turned through a link mechanism 3, and the protective cover 2 is brought down to protect the fixed sheet 1 from inside. Therefore, sticking of dust onto the fixed sheet 1 can be prevented when the valve piece 4 is in the opened state, and the sealing performance in the case when the valve piece 4 is closed can be maintained at a high level.

The valve body can be detached from the fixed seat portion and the valve body can be closed. on the other hand,
When the valve body is opened, the protective cover protects the fixed seat and eliminates problems caused by dirt.
