Description

气动软密封放料阀
技术领域
本发明涉及一种阀门，特别是涉及一种生物制药工业管道使用的对金属固体颗粒进行放料的阀门。
技术背景
目前，在生物制药工业管道上使用的金属固体颗粒放料阀门多为浮动球阀、固定球阀以及V型球阀，而该类阀门的密封副(即阀座与球状阀芯)始终接触，容易磨损；同时在全关位置时密封副之间形成由低到高的环状，在开关的过程中极易产生固体颗粒卡、挂等现象，使阀门开关失效。且现场工况管道介质为易燃、易爆与有毒的气体，使用该类阀门，如气体与金属固体颗粒接触，则安全系数很低。
发明内容
本发明的目的在于克服上述的不足，而提供一种密封性能良好、结构形式在介质为金属固体颗粒时不易产生卡、挂现象的气动软密封放料阀。
本发明的目的通过如下的技术方案来实现：气动软密封放料阀，包括阀体、阀盖、阀瓣、摇杆、阀杆，所述阀杆通过连接件与气动执行机构连接，所述阀瓣为带橡胶密封圈、金属压圈的组合件而与摇杆相连；所述阀体带有气体置换法兰。所述阀体带有视窗。
采用本发明结构后，由于密封副采用硬软材料结合，密封性能能够实现零泄漏；在阀门全开到全关的过程中，固体金属颗粒基本杜绝卡、挂等现象。从而达到工况要求，提高现场安全系数；阀体带视窗前后各一个，可直接观察管道中加料情况，如出现异常，可及时维修。
附图说明
图1为本发明气动软密封放料阀的结构示意图。
图2为图1的左视图。
图3为本发明在使用时的工作流程图。
具体实施方式
参照附图1、图2，本发明气动软密封放料阀，包括阀体1、阀盖2、阀瓣3、摇杆4、阀杆5(及填料6、填料压盖7)，所述阀杆5通过连接件8(叉形)与气动执行机构9连接(在阀体外)，所述阀瓣3为带(三元乙丙)橡胶密封圈、金属压圈的组合件而与摇杆4相连；所述阀体1(其正下方)带有气体置换法兰11(口径DN15/压力PN16，以方便置换管道中的空气)。所述阀体1带有视窗10(为前后各一个)，以方便观察。
所述阀瓣3、摇杆4、阀杆5依次相连，气动执行机构9(气缸组件)在现场气源提供的压力作用下，通过控制阀杆工作而由摇杆带动阀瓣打开或关闭，以实现阀门自动全开到全关的过程，使金属固体颗粒基本杜绝卡、挂等现象，从而达到工况要求，提高现场安全系数。
本发明气动软密封放料阀适用于生物制药工业管道工况简介，见附图3：在化工生物制药生产过程中，需要添加一种活泼金属的固体颗粒，以加锂料举例说明(安全阀为常开状态)：由于锂料固体颗粒需与空气隔离，首先关闭开关阀1、2，打开该放料阀；此时置换管路中的空气，检测合格后关闭该放料阀；加入锂料到料斗，打开开关阀1，在锂料加入到该放料阀中后关闭开关阀1。同时置换管路中的空气，检测合格后，首先打开开关阀2，然后打开放料阀，将锂料投入到炼化装置中进行生产；同时关闭开关阀2、放料阀。在采用本发明气动软密封放料阀后，固体金属颗粒基本杜绝卡、挂等现象；从而达到工况要求，提高现场安全系数。
