Description

一种在线检测蝶阀内漏的系统
技术领域
本发明属于检测领域,特别涉及一种在线检测蝶阀内漏的系统。
背景技术
蝶阀作为常见阀门一种,是管路流体输送系统中控制部件,其可用来改变通路断面和介质流动方向。在长期高负荷使用过程中,由于杂质堵塞、阀板磨损、内密封磨损等原因都能导致阀门内漏。当阀门处于内漏状态时,现场人员只能通过手持检漏仪或日常工作经验判断,而中控人员只能通过物料平衡判断。当今化工生产负荷大,如果通过工人经验来发现阀门内漏的话,不能及时发现泄露的话,石油物料通过阀门内漏流失过多。这样既有害化工厂利益,也对安全埋下隐患。
发明内容
本发明目的在于提供一种在线检测蝶阀内漏的系统。
一种在线检测蝶阀内漏的系统,其特征在于,包括:在线内漏检测单元、数据处理单元、紧急补漏单元;所述在线内漏检测单元连接数据处理单元,检测到阀门内漏的信号发送至数据处理单元,数据处理单元接收到在线内漏检测单元发送的阀门内漏信号,连接所述紧急补漏单元,通过设置好的临时补漏设备,防止石油物料继续泄露。
进一步的,根据权利要求1所述的在线检测蝶阀内漏的系统,其特征在于,所述在线内漏检测单元为设置内嵌于阀门的启闭件与阀座密封面间的接触处的内漏检测带;其中,所述内漏检测带为感应铂线,所述感应铂线上涂敷防腐层。
进一步的,根据权利要求1所述的在线检测蝶阀内漏的系统,其特征在于,所述内漏检测带为环绕阀座密封面铺设且存在间隔,其中间隔长度为1厘米。
进一步的,根据权利要求2所述的在线检测蝶阀内漏的系统,其特征在于,阀门内漏检测带的温度值发生变化,根据获取的铂的电阻值和温度的转换关系,得出内漏点的电阻数据,进而获取具体阀门内漏的位置;其中,所述内漏检测带温度发生改变后,转换为温度数据的步骤为:根据关系式测量温度×0.385+100欧姆=测量电阻;其中检测到的温度与阻值的变化关系为:当感应铂线为0度时,电阻阻值为100欧姆,在100度时,电阻阻值为138.5欧姆,所述感应铂线的阻值随着石油物料温度上升而上升。
进一步的,根据权利要求1所述的在线检测蝶阀内漏的系统,其特征在于,所述紧急补漏单元为安装于蝶板中心且阀门背面的堵漏装置,所述堵漏装置为可360旋转的射胶器。
进一步的,根据权利要求1所述的在线检测蝶阀内漏的系统,其特征在于,射胶器射出的物料为聚氨酯堵漏剂。
进一步的,根据权利要求5所述的在线检测蝶阀内漏的系统,其特征在于,所述在线内漏检测单元环绕阀座密封面铺设的感应铂线检测到内漏物料引起电阻变化,而根据已预设好位置间隔的感应铂线,判断出具体泄露位置;所诉紧急补漏单元根据检测的内漏位置,旋转射胶器,以1MPa的压力射出聚氨酯堵漏剂,射出时间为2S,达到射出时间后,自动关闭射胶器。
