    摘要： Valve mechanism (10) for a thermo hydraulic system in which a pressurized fluid circulates, particularly at high pressure. The mechanism (10) comprises a first body (11) provided with at least a housing seating (15) in which a seal element (13) of elastomer material is disposed, and a second body (12) associated slidingly with the first body (11) and defining with the first body (11) at least a pipe (14) through which the pressurized fluid passes. The first body (11) and the second body (12) are reciprocally movable to define a first closed condition in which the second body (12) elastically compresses the seal element (13) and prevents the passage of the fluid through the pipe (14), and a second open condition in which the second body (12) is distanced from the seal element (13) and allows the fluid to pass through the pipe (14). The first body (11) comprises radial mechanical stop members (20) which, in the first closed condition, define a raised abutment and end-of-travel tooth for the second body (12), so as to determine a controlled compression of the seal element (13).

    摘要： A valve having a normally non-rising stem (30a, b) journaled between bearings (38a, b 40a, b) is equipped with an energized drive spring (56a, b) for positively engaging back- seatseal surfaces (64a, b,66a, b) upon melting of fusible ring (52a, b). The spring (56a, b) is compressed axially against the retainer (46a, b) by the cooperative action of the compression nut (58a, b) and the tubular spacer (49b, 50a, b), thereby normally avoiding undesirable axial thrust on the bearings (38a, b, 40a, b).

    摘要： A ball valve including a valve body that includes a first body member and a second body member. The valve body defines a valve axis and a fluid flow path. A ball element has a port and a ball stem, and is rotatable about a ball stem axis between an open position providing fluid flow through the fluid flow path and a closed position inhibiting flow through the fluid flow path. A body seal is located between the first body member and the second body member and defines a thickness that decreases as the body seal extends away from the valve axis. A stem seal defines a substantially frusto-conical shape and is arranged in the valve body. The ball stem extends through the stem seal to form a seal between the ball stem and the stem seal and between the stem seal and the valve body.
