摘要： A sealing assembly (20) for a ball valve comprises two non compressible and relatively movable members, for example the ball (24) and seal housing (26) of a ball valve, having located therebetween a sealing element (32) which is inflatable by the introduction of hydraulic fluid.
The sealing element (32) is located in a recess in member (26) so that when the hydraulic pressure is released the element (32) retracts into the recess to release the sealing engagement and facilitate the relative movement of members (24, 26). A resilient rubber ring (40) is provided to bias the seal housing (26) away from the position of sealing engagement to also facilitate movement of members (24, 26). A second sealing element (25) is also provided. Both elements are carried by the seal housing (26) which is in the form of an annular piston movable by the hydraulic fluid.

摘要： The invention relates to a gate valve (1) for a chemical plant. In order to provide a gate valve with a rather simple design and reliable sealing properties, the invention provides that the gate valve (1) comprises:
• a valve housing (2) having an upper opening (2.1) and an opposite lower opening (2.2);
• an upper sealing seat (8) and a lower sealing seat (9) disposed on the valve housing (2);
• a valve gate (3) movably disposed in the valve housing (2), for blocking a path between the openings (2.1, 2.2) in a closed position and opening said path in an open position, the valve gate (3) comprising a first plate (4) having lower surface (4.2) with a blind recess (4.3) and a second plate (5) at least partially disposed in the blind recess (4.3);
• wherein, in the closed position, the upper sealing seat (8) sealingly engages the first plate (4), the lower sealing seat (9) sealingly engages the second plate (5) and the second plate (5) is at least indirectly in contact with the first plate (4).

摘要： The flexible sealing seat (6) is essentially comprised of circular ring-shaped metallic membranes (9, 10) having approximately identical surfaces. The metallic membranes (9) and (10) are joined to one another on their outside diameter by weld seam (18) and are connected in a tightly sealed manner to the ring (16) on their inside diameter by weld seams (19) and (20). Both membranes (9) and (10) and the ring (16) form a pressure space (11) together. This pressure space (11) in which pressure Ps Is effective, is connected, via a boring (17), to the inner space of the housing (7) in which pressure Pb is effective. The pressure space (11) also comprises a connection to the external shut-off device (8) via the boring (12) and the pipe (13). When the shut-off device (1) is in a completely unpressurized state, the membrane (10) is also in contact, at least on an uninterrupted circular line, with the shut-off element (2).

摘要： The valve includes an inflatable seal element (86) located in the housing seat and a gas-pressure-purge arrangement (116,118,123,124,111,112). The inflatable seal element (86) is inflated by means of pressurized fluid to grow in size and close up clearances between gate (50) and seat, thereby establishing a gas-tight seal between the two parts, at will. This can be done, for example, after the valve has been operated to close (slide gate (50) driven into the valve housing) and when a gas-pressure-tight seal is desired. Prior to this event, the gas-pressure-purge arrangement (116,118, 123, 124, 111, 112) is activated to blast-off solid particles from the gate surfaces where these make contact with the inflatable seal element (86). Furthermore, the inflatable seal element (86) can be deflated to shrink in size, thereby providing increased clearance between gate (50) and seat, when desired. This can be done just prior to the moment when the gate (50) is to be operated (driven out of the housing) to open the valve.
