    摘要： A mixture preventing valve includes a first flow passage (11) for allowing a first fluid to flow; a second flow passage (12) for allowing a second fluid to flow; a communication passage (13) for allowing the first flow passage (11) and the second flow passage (12) to communicate with each other; a valve body (17) that moves to open and close the communication passage (13); and a valve seat (18) that is provided on an inner wall surface of the communication passage (13), and comes into contact with the valve body (17). The valve body (17) includes a first valve body piece (17a) and a second valve body piece (17b) that are arranged side by side in a state of being separated from each other in a movement direction of the valve body (17). The valve seat (18) comes into contact with respective outer peripheral surfaces of the first valve body piece (17a) and the second valve body piece (17b). In the inner wall surface, a portion (18a) where the valve seat (18) comes into contact with the outer peripheral surface of the first valve body piece (17a), and a portion (18b) where the valve seat (18) comes into contact with the outer peripheral surface of the second valve body piece (17b) exist on the same plane.

    摘要： A double seat valve comprising a valve housing (3), a first closing element (11), a second closing element (21), a leakage chamber (6) arranged intermediate the first and second closing elements (11, 21), the second closing element (21) connected to the second displacement rod (22) via spokes (23, 24), wherein at least one of the spokes (23, 24) comprises: a leading edge (41) that faces the leakage chamber (6) and extends in a radial direction (D2) outwards from the second displacement rod (22); and first and second sides (42, 43) that extend from the leading edge (41) in a direction (D1, D3) from the leakage chamber (6) to the drain passage (7) on a respective side of the spoke (23).

    摘要： A steam valve 10 of an embodiment includes: a valve element 32 of a steam control valve 30, the valve element 32 being provided to be movable in an up and down direction; a valve element 42 of a main stop valve 40, the valve element 42 being provided under the valve element 32 coaxially with the valve element 32 to be movable in the up and down direction; a valve seat 60 with which the valve element 32 and the valve element 42 come into and out of contact; and a guide tube 43 slidably supporting a valve rod 41 including the valve element 42, and having a flange portion 43a at a bottom side in a casing 20. The steam valve 10 further includes: the casing 20 housing the valve element 32, the valve element 42, the valve seat 60, and the guide tube 43; a drain discharge hole 23 formed at a bottom side of the casing 20; a drain pipe 70 provided with a shutoff valve 71 and communicating with the drain discharge hole 23; and a flow direction changing part 80 which changes a direction in which steam having passed between the valve element 32 and the valve seat 60 and flowing along the guide tube 43 flows toward the drain discharge hole 23.

    摘要： A valve (10) for sealing and selectively opening a flow path from a water-filled inlet (210) to a dry outlet (220) includes a valve body (100) having a valve opening (230) surrounded by first and second annular valve seat regions (110, 120). A drainage channel (510, 512)) connects to a space between the first and second annular valve seat regions (110, 120). A plug (300) is displaceable between an open state and a closed state for closing the valve opening (230). The plug has a first annular seal (310) for sealing against first annular valve seat region (110) and a second annular seal (350) for sealing against the second annular valve seat region (120). The second annular seal (350) is a flexible seal deployed so that it closes prior to closure of the first annular seal (310). Second annular seal (350) is elastically deformed so as to be pressed into contact with the second annular valve seat (120) when the plug (300) reaches its closed state.
