产品型号：Q47F 产品口径：DN50-DN800 产品压力：PN1.6-PN10.0MPA 产品材质：碳钢 CF8 固定球阀，球体带有固定轴的球阀，称为固定球阀。固定球阀主要用于高压大口径。根据阀座密封圈的安装不同，固定球阀可以有两种结构：球体前密封的阀座，球体后密封的阀座1、结构特点 2、整体结构 如图5所示。具有全通道、紧急密封、防火等特点。 3、全通径 阀门流道孔直径与管和径内径一致，更于管线清扫。 4、阻塞与排泄 阀门处于关闭状态时，上下游侧的阀座使流体阻断，阀体中腔的积治物可以排泄，排泄装置如下机能： ① 事前可检查阀座是否泄漏损伤; ②减少介质更换对阀门的污染; ③ 在工作压力下，阀门处于全开或全关状态时，可更换阀杆部填料函。（如图5所示排泄装置是排污塞） 5、自动泄压 阀门中腔停滞的介质由于温度升高，而出现异常升高时，阀座或阀体上安装的安全阀可以自动泄压。 6、防火结构 采用双重密封，当发生火灾时，非金属阀座烧损后，介质将球体压紧在阀体上的金属密封面阻止介质大量漏出，符合API607规定。 7、紧急密封 阀座及阀杆密封件出现损伤而引起泄漏时，通过注脂阀注入密封脂可以起瞬时应急密封作用。 8、阀杆加长 阀杆加长适用于地下安装及低温介质用，加长尺寸，根据需要确定。操作方式有手动、气动、电动、气液联动、液动等。 二、主要零件材料
