  • Gate valve
    Patent number: 11092246
    Abstract: A gate valve comprising a plurality of first force-applying units built in a valve box; a second force-applying unit disposed between a first movable valve and a second movable valve; and a third force-applying unit. The first force-applying units are driven by incompressible fluid and have a function of applying a force to the first movable valve to be directed to the first opening portion in the flow passage direction and thereby causing the seal portion to be in close contact with a valve box inner surface located at the periphery of the first opening portion. The gate valve includes an incompressible-fluid driver that drives, the first force-applying units by incompressible fluid.

  • Gate valve
    Patent number: 10612673
    Abstract: A gate valve of the invention includes a valve box, a neutral valve body, and a rotation shaft. The neutral valve body includes a neutral valve and a movable valve. The movable valve includes a first movable valve and a second movable valve. The gate valve includes a plurality of first force-applying units, a second force-applying unit, and a third force-applying unit. The third force-applying unit applies a force to the first movable valve. The first force-applying units apply a force to the first movable valve and thereby causing the seal portion to be in close contact with a valve box inner surface located at a periphery of the first opening portion. The second force-applying unit drives the first movable valve and the second movable valve so that thicknesses thereof in the flow passage direction are adjustable.
