Abstract

This gate valve is equipped with a valve box, a middle valve body, a position-switching means, a movable valve part, a first movable valve part, a first biasing part, a second movable valve part, a second biasing part, and a third biasing part.

Description

technical field [0001] The present invention relates to a kind of shut-off valve of swing type, direct acting type, door type, etc. suitable for making the valve core slide on the basis of the action of using the valve core (valve plate) to open and close the flow channel, and suitable for making the valve core perform sliding action. Swing type spool valve with slide action. [0002] In particular, the present invention relates to a method for shutting off (closing) a flow path connecting two spaces with different pressures and carrying out different processes in a vacuum device, opening the shutoff state (connecting the two spaces), and adjusting the flow path of the valve. Shut-off valves and spool valves that restrict a part of the flow passage (restrict the opening area of ​​the flow passage) by opening. [0003] This application was filed in Japanese Patent Application No. 2011-053141 filed on March 10, 2011, Japanese Patent Application No. 2011-059704 filed on March 17...
