1 CPVC封装的阀杆加长件并不用于水平球阀系列。 1 CPVC housed stem extensions are not intended for the horizon ball valve series.

基本的阀杆加长件–在所有阀杆加长件的外部支撑板下，安装配置TFE圆盘的一个CPVC推力轴承底板。这个轴承总成承受着碳钢或304不锈钢加长杆的重量，加长杆的长度以1英尺为单位增量，最长可达10英尺。因此，当外部支撑板成为阀门上的结构部件的一员时，就可以避免不适当的重量施加在塑料管道上和/或阀门运转的腐蚀性冻结现象的发生。1/4英寸厚4英寸宽12英寸长外部支撑板，以及其它扶助的五金件，或是碳钢，外喷灰色漆，或者是未上漆的304不锈钢，主要取决于所选择的加长杆。 　　Basic Stem Extension–A CPVC thrust bearing plate with a TFE disk is mounted under the external support plate on all stem extensions. This bearing assembly carries the weight of the carbon steel or 304 stainless steel extension rods, which are available in one-foot increments up to 10 feet. Thus, when the external support plate is anchored to a structural member over the valve, undue weight on the plastic piping and/or corrosion freeze-up of valve operation is avoided. The 1/4" thick 4" x 12" external support plate, as well as other associated hardware, is carbon steel, painted gray, or unpainted 304 SS, depending on the extension rod selected. 　　CPVC封装阀杆加长件–与上述的基本阀杆加长件相同，封装的阀杆加长件也与碳钢或304不锈钢加长杆一起按照1英尺增量供货。封装采用DN40的CPVC管道，配置有改装的球阀执行机构安装法兰，采用液状粘固剂粘结在每个端口。如果是蝶阀，或者是执行机构的安装，底部封装法兰用螺栓安装在阀门的顶部法兰上，如果是球阀，就需要增加。为了密封外壳，使得流体不会从外壳内泄露出来，需要一个与阀门弹性密封相配的垫圈，安装在底部法兰连接件里，而无论所连接的阀门是什么类型。顶部外壳法兰用螺栓安装在CPVC推力轴承板的底部。 　　CPVC Housed Stem Extension–As with the basic stem extension described above, the housed stem extensions are offered with CS or 304 SS extension rods in one-foot increments. The housing utilizes 1 1/2" CPVC pipe with modified ball valve actuator mounting flanges solvent cemented to each end. The bottom housing-flange is bolted to the valve top flange, in the case of a butterfly valve, or to the actuator mount, which is added, in the case of a ball valve. And a gasket, matching the elastomeric valve seals, is installed in the bottom flange joint, regardless of attached valve type, in order to seal external fluid from the housing interior. The top housing-flange is bolted to the bottom of the CPVC thrust bearing plate. 　　通用–对于基本的和CPVC封装的两种阀杆加长件，用于所有球阀加长件上的底部杆连接件都配置旋转止动装置。可提供Chemtrol标准的橙色手柄，用于旋转配置在DN15至DN25手工操作的球阀的加长件上。对于更大的球阀，以及所有蝶阀，可提供适当的蝶阀手柄和刻度板，用于阀杆加长件的手动操作。 　　General–For both the basic and CPVC housed stem extensions, the bottom rod coupling utilized for all ball valve extensions is fitted with turning-stops. The Chemtrol standard orange handle is supplied to turn the extensions for 1/2" through 1" manually operated ball valves. For the larger ball valves, as well as all butterfly valves, the appropriate butterfly valve handle and index plate are supplied for manual operation of the stem extensions. 　　一个齿轮操作机构可以容易的安装在所有阀杆加长件的外部支撑板的顶部。从第28页的齿轮操作机构和蝶阀选配件表格中，选择齿轮操作机构和驱动套管。对于用在所有球阀上的阀杆加长件，应该采用29240018齿轮操作机构和29241014驱动套管。 　　A gear operator may easily be mounted on top of the external support plate of all stem extensions. Select the gear operator and drive bushing from the table for gear operators and options for butterfly valves on page 28. The 29240018 gear operator and the 29241014 drive bushing should be used on the stem extensions for all ball valves.
