Abstract

真空取样器是一种化工减压回流取样装置,它是由回流管、进料阀、进气阀、异径管、取样阀、采出管连接而成,进料阀的一端连接管线焊接在回流管的中间,进料阀的另一端连接着异径管;异径管的另一端与取样阀连接,取样阀的一端连接着采出管;在异径管的中间安装着进气阀;异径管中间的直径大于两端的直径,异径管两端的直径与采出管的直径相等;工作时,先关闭进气阀和取样阀,使管道与外界空气隔绝,然后开进料阀,使异径管中成为负压,塔内的物料流进异径管,然后关闭进料阀;打开进气阀,异径管变成常压,最后开取样阀流出物料;本实用新型结构简单,操作方便,提高了功效。

Description

真空取样器
[0001] 一、技术领域:本实用新型涉及一种化工减压回流取样装置,尤其是真空取样器。
[0002] 二、背景技术:对于减压塔(真空塔),原来取样分析产品是否合格时,先关闭真空塔,破真空,真空塔处于常压状态时,然后取样;取样后再开塔,进行生产。因为关、开塔,影响正常生产,生产效率低;设备容易损坏。
[0003] 三、发明内容:本实用新型的目的是提供一种结构简单,操作方便的真空取样器, 它克服了原来技术存在的缺点,本实用新型的目的是这样实现的,它是由回流管、进料阀、 进气阀、异径管、取样阀、采出管连接而成,进料阀的一端连接管线焊接在回流管的中间,进料阀的另一端连接着异径管;异径管的另一端与取样阀连接,取样阀的一端连接着采出管; 在异径管的中间安装着进气阀;异径管中间的直径大于两端的直径,异径管两端的直径与采出管的直径相等。
[0004] 工作时,先关闭进气阀和取样阀,使管道与外界空气隔绝,然后开进料阀,使异径管中成为负压,塔内的物料流进异径管,然后关闭进料阀;打开进气阀,异径管变成常压,最后开取样阀流出物料。
[0005] 本实用新型结构简单,操作方便,提高了功效。
[0006] 四、附图说明:图1为真空取样器的结构示意图,图中1、回流管 2、进料阀
3、异径管 4、取样阀 5、采出管 6、进气阀
[0007] 五、具体实施方式:实施例1、本实用新型是由回流管1、进料阀2、异径管3、取样阀
4、采出管5、进气阀6连接而成,进料阀2的一端连接管线焊接在回流管1的中间,进料阀2 的另一端连接着异径管3 ;异径管3的另一端与取样阀4连接,取样阀4的另一端连接着采出管5。
[0008] 在异径管3的中间安装着进气阀6 ;异径管3中间的直径大于两端的直径,异径管 3两端的直径与采出管5的直径相等。
