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
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。
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。
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。
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。
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
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。
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。
