Abstract
PURPOSE:To make it possible to surely press a gate valve against a valve seat upon valve closing operation by coupling a drive plate with the gate plate in a gate valve by use of a link. CONSTITUTION:A valve seat 105 composed of an O-ring 104 is disposed in a groove 103 formed in a side wall around an opening 102. A drive plate 109 is movably inserted on a guide shaft 11 which are attached on the side plate through the intermediary of attaching plates 115, 116. A link 108 is supported at one end to a pin 110 projected from the drive plate, and a gate plate 106 is supported to the other end of the link 108 through the intermediary of a pin 107. The gate valve 106 and the drive plate 109 are urged toward each other by means of a spring 112. When the drive plate 109 is moved up, a valve element 106 abuts against a roller 117 on the attaching plate 115, and thereafter is moved leftward so as to be pressed against the valve seat 105. With this arrangement, it is possible to stably and surely shut off the gate valve with a simple arrangement.
