    • A valve assembly comprises an upper valve assembly (9a) and a lower valve assembly (9b). The upper valve assembly includes a valve body (10), a spring retainer (11) and an upper spring (12). The lower valve assembly includes a retainer ring (13), an O-ring (14) and a valve seat member (15). The valve body (10) comprises a valve disc (10a) and a valve stem (19b). The valve disc (10a) has a lower peripheral surface (16) which is bevelled and the lower extremity of the bevelled surface meets an annular protrusion (17) which has a flat lower surface. The O-ring (14) fits within respective grooves provided in the retainer ring (13) and the valve seat member (15). The valve seat (15) is arranged to be located in a valve port (28), and when the upper valve assembly is moved downwardly the annular protrusion (17) is forced against the O-ring (14) which then forms an additional seal with the adjacent housing of the valve port (28) to completely close the valve assembly.
    • 阀组件包括上阀组件(9a)和下阀组件(9b)。 上阀组件包括阀体(10),弹簧保持器(11)和上弹簧(12)。 下阀组件包括保持环(13),O形环(14)和阀座构件(15)。 阀体(10)包括阀盘(10a)和阀杆(19b)。 阀盘(10a)具有倾斜的下周边表面(16),倾斜表面的下端与具有平坦下表面的环形突起(17)相遇。 O形环(14)装配在设置在固定环(13)和阀座构件(15)中的相应凹槽内。 阀座(15)布置成位于阀端口(28)中,并且当上阀组件向下移动时,环形突起(17)被迫压靠O形环(14),该O形环然后形成另外的密封 与阀口(28)的相邻壳体完全关闭阀组件。

    • A diaphragm-type valve uses a multiple annular metal diaphragm (36) welded about its inner periphery to a valve operating stem (34). The diaphragm is sealingly clamped about its outer periphery to the valve body and is also clamped about its inner periphery at a location spaced outwardly of the weld to prevent the weld from being subjected to flexure stresses during valve actuation. The outer periphery of the diaphragm (36′) may be welded to the valve body (10′) outwardly of the outer clamp. The actuating assembly (20) is arranged to produce non-rotary, reciprocatory movement of the operating stem (34) through a bonnet mounted rotary actuator (116). A stem tip seal (16) comprises a metallic seal ring (152) backed by a PTFE ring (158) and surrounded by a harder plastics ring (160) held captive by a sleeve (166).
    • 隔膜式阀使用围绕其内周焊接到阀操作杆(34)的多个环形金属隔膜(36)。 隔膜围绕其外周围密封地夹紧到阀体上,并且还在其内周边处被夹持在与焊缝的外部隔开的位置处,以防止焊接在阀致动期间受到挠曲应力。 隔膜的外周边(36分钟)可以与外部夹具外侧的阀体(10分钟)焊接。 致动组件(20)被布置成通过安装有发动机罩的旋转致动器(116)产生操作杆(34)的非旋转,往复运动。 杆头密封件(16)包括金属密封环(152),所述金属密封环(152)由PTFE环(158)支撑并由被套筒(166)保持的较硬的塑料环(160)包围。

    • A valve (20) having a protective ported housing (22, 24, 32) and an electromagnet (70) and a reciprocatively situated armature (90) located therein. The control valve (20) further has a movable valve plate (160) and stationary valve seat (110) operatively connected to the armature (90) and situated within a passage (40) to control the flow of fluid therethrough. The valve seat (110) includes a plurality of circularly spaced fluid receiving passages (146) and a single annular fluid exit passage (148). The valve plate (160) has a like plurality of circularly spaced passages (170) located in a mating surface (162) adapted to mate with a corresponding surface (142) of the valve seat (110) and to seal off the flow of fluid through the valve seat.
    • 具有保护端口壳体(22,24,32)和电磁体(70)的阀(20)和位于其中的往复位置的电枢(90)。 控制阀(20)还具有可操作地连接到电枢(90)并且位于通道(40)内的可动阀板(160)和固定阀座(110),以控制流体通过其中的流动。 阀座(110)包括多个圆形间隔开的流体接收通道(146)和单个环形流体出口通道(148)。 阀板(160)具有位于配合表面(162)中的相似多个圆形间隔通道(170),该配合表面适于与阀座(110)的对应表面(142)配合并且密封流体流 通过阀座。
