截止阀标准大全|截止阀的作用
一、编辑整理截止阀标准意义何在？
信茂截止阀的启闭件是塞形的阀瓣，密封面呈平面或锥面，阀瓣沿流体的中心线作直线运动。阀杆的运动形式，有升降杆式（阀杆升降，手轮不升降），也有升降旋转杆式（手轮与阀杆一起旋转升降，螺母设在阀体上）。截止阀只适用于全开和全关，不允许作调节和节流。
由于截止阀种类繁多，同一个截止阀可以做成不同的标准，不同的标准在管道连接，试验压力以及管道使用都有差别，为了您在使用的时候，能将截止阀对号入座，信茂技术部特编辑整体出截止阀的标准大全，供您参考！落实到工况比较特殊的场合，建议您联系我们技术部，为您做选型把关，避免不必要的损失。

三、信茂截止阀的作用：
截止阀在管道起着举足轻重的作用，大家在选用截止阀的时候，一定要配合截止阀的优缺点，截止阀的工作原理，截止阀的适用范围，然后结合截止阀的型号编制和截止阀的分类，对截止阀进行精确的选择，以最大限度的发挥出截止阀的作用。下面是截止阀落实到具体工况的作用。
1、高温、高压介质的管路或装置上宜选用截止阀。如火电厂、核电站，石油化工系统的高温、高压管路上。
2、管路上对流阻要求不严的管路上。即对压力损失考虑不大的地方，可以选用截止阀。
3、小型阀门可选用针阀、仪表阀、取样阀、压力计阀等。
4、有流量调节或压力调节，但对调节精度要求不高，而且管路直径又比较小，如公称通经≤50mm 的管路上，宜选用截止阀。
5、合成工业生产中的小化肥和大化肥宜选用公称压力PN160 公称压力16MPa 或PN320 公称压力32MPa 的高压角式截止阀或高压角式节流阀。
6、氧化铝拜耳法生产中的脱硅车间、易结焦的管路上，易选用阀体分开式、阀座可去处的、硬质合金密封副的直流式截止阀或直流式节流阀。
7、城市建设中的供水、供热工程上，公称通经较小的管路，可选用截止、平衡阀或柱塞阀，如公称通经小于150mm的管路上。 最明显的优点是： 在开启和关闭过程中，由于阀瓣于阀体密封面间的摩擦力比闸阀小，因而耐磨。 开启高度一般仅为阀座通道直径的1/4，因此比闸阀小的多。 通常在阀体和阀瓣上只有一个密封面，因而制造工艺性比较好，便于维修。
