J47H高压角式截止阀、节流阀，J47H高压平衡角式截止、节流阀原理，J47H高压平衡角式截止、节流阀规格，J47H高压平衡角式截止、节流阀厂家，J47H高压平衡角式截止、节流阀报价 J44H角式截止阀，J44H角式截止阀原理，J44H角式截止阀规格，J44H角式截止阀厂家，J44H角式截止阀报价 截止阀是指关闭件(阀瓣)沿阀座中心线移动的阀门。根据阀瓣的这种移动形式，阀座通口的变化是与阀瓣行程成正比例关系。由于该类阀门的阀杆开启或关闭行程相对较短，而且具有非常可靠的切断功能，又由于阀座通口的变化与阀瓣的行程成正比例关系，非常适合于对流量的调节。因此，这种类型的阀门非常适合作为切断或调节以及节流使用。

J47H高压角式截止阀选用原则是：
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。
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。
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。 *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。
截止阀优点
1、结构简单，制造和维修比较方便。
2、工作行程小，启闭时间短。
3、密封性好，密封面间磨擦力小，寿命较长。
