摘要： A valve assembly, comprising: a valve housing body (1181) extending along a longitudinal axis X between a first end and a second end and defining a cylindrical passage (1185) therethrough from the first to the second end; a fluid inlet (1110) at the first end for receiving a pressurized fluid; and a fluid outlet (1120) provided in between the first and second end of the housing body; and a piston (1300) provided in said cylindrical passage, said piston being axially movable between a first position wherein said fluid outlet is blocked by said piston such that the piston blocks the flow of fluid from the inlet to the outlet, and a second position wherein said outlet is not blocked by said piston and a fluid flow path is formed from the inlet to the outlet; and wherein said valve assembly further comprises helical guide grooves (1401) formed in the cylindrical passage and the piston comprises radially extending guide pins (1302) configured to engage in the respective helical guide groove such that as the piston moves axially from the first position, the guide pins travel along the helical guide grooves to cause rotation of the piston relative to the housing body, and the valve assembly further comprising a circumferential groove (1402) at an end of the helical guide grooves such that the guide pins travel from the helical guide grooves into the circumferential groove, wherein when piston is in the second position the guide pins rotate around the circumferential groove.

摘要： A gate valve with a shake prevention mechanism is disclosed. In a connection mechanism (12) that connects a valve shaft (4) to air cylinders (10), shake prevention mechanisms (36A) and (36B) are disposed at facing portions at which outer side surfaces (21a) of side frames (21) face inner side surfaces (13c) of housings (13) of the air cylinders (10) and/or facing portions at which inner side surfaces (21b) of the side frames (21) face left-hand and right-hand side surfaces (22a) of a center frame (22). The shake prevention mechanisms (36A) and (36B) include a sliding member (38) that is disposed on a sliding surface (37) that is formed on one of two surfaces that face each other and on the other and a spring mechanism (39) that presses the sliding member (38) in a direction in which the sliding member (38) comes into contact with the sliding surface (37).

摘要： A hot and cold water mixing valve including a temperature adjusting dial D, and a cylindrical casing 1 having formed therein a hot water inlet a and a cold water inlet b is provided with a control valve member 2 in which one end is subjected to a load from a biasing member 4 and the other end is subjected to a load from an actuator 5, and an opening/closing ratio between the hot water inlet a and the cold water inlet b is changed by balancing between the loads applied by the biasing member 4 and the actuator 5, to adjust a mixture ratio between the hot water which flows in through the hot water inlet a and the cold water which flows in through the cold water inlet b, and a temperature adjusting means (8, 900) whose one side is fixed to the temperature adjusting dial D and whose other side adjusts a position of the control valve member 2 through the biasing member 4. A tapered skirt portion 94 which spreads in a radial direction is formed at an end on the control valve member 2 side of the temperature adjusting means (8, 900).

摘要： A check valve (2) comprises a valve housing (4) defining a valve opening (6) and a pair of flapper elements (10) pivotably mounted relative to the housing (6) for rotation between an open position in which they permit fluid flow through the opening (6) and a closed position in which they prevent fluid flow through the opening (6). Each flapper element (10) comprises a first surface (18) facing the opening (6) and a second surface (20) opposite the first surface (18) and facing away from the opening (6). The valve further comprises a bowed leaf spring member (22) mounted to the second surface (20) of each flapper element (10). The leaf spring members (22) are arranged such that when the flapper elements (10) move towards the closed position, the bowed leaf spring members (22) move into engagement with one another.
摘要翻译：止回阀（2）包括限定阀开口（6）的阀壳体（4）和相对于壳体（6）可枢转地安装的一对挡板元件（10），以在允许流体流动的打开位置通过开口（6）和阻止流体流过开口（6）的关闭位置。每个挡板元件（10）包括面向开口（6）的第一表面（18）和与第一表面（18）相对并且背离开口（6）的第二表面（20）。该阀还包括安装到每个挡板元件（10）的第二表面（20）上的弓形弹簧构件（22）。板簧元件（22）布置成使得当挡板元件（10）朝向关闭位置移动时，弯曲的板簧元件（22）移动成彼此接合。
