Description
技术领域
本发明涉及一种制程排气管道中安装对接密封技术，具体涉及一种管道密封安装方法。
背景技术
目前为大家熟知的管道密封件一般采用整体开模成型或缠绕承插式,这两种密封方式因为生产方式的限制,导致其只能用于小口径风管,而且加工成本太高不利于酸碱排气管道使用。
发明内容
本发明提供一种管道密封安装方法，克服现有密封垫适用范围、加工难度大、加工成本高的问题，同时提高其所服务的产品安全和管道自身安全。
为实现上述目的，本发明提供一种管道密封安装方法，其特点是，该方法包含以下步骤：
步骤1、在一对管道对接处分别设置翻边；
步骤2、密封条一侧粘贴双面胶；
步骤3、密封条通过双面胶粘贴在两根对接管道中任意一根管道的翻边处，并取翻边的任意点为起点绕翻边一周设置；
步骤4、密封条首尾连接后，两根管道翻边对接，将密封条夹设在两根管道的翻边之间；
步骤5、两根管道对接的翻边处固定连接，并相对锁紧对密封条进行挤压。
上述的密封条绕管道翻边一周后，首尾交叉设置。
上述的密封条采用拉丝挤出工艺制成。
上述的密封条采用聚四氟乙烯材料。
两根管道通过法兰连接，所述密封条设置于法兰连接的螺栓相对于管道的内侧。
两根管道为直管，其对接处分别设置不等边卷制法兰，通过在不等边卷制法兰上串设螺栓实现两根管道法兰连接。
上述螺栓串设于两根管道的法兰连接处，通过螺母配合实现对两根管道固定，并通过旋进螺栓使法兰相向锁紧，并对密封圈进行挤压。
上述螺栓与法兰之间设有平垫；螺帽与法兰之间设有平垫和弹垫。
一种上述的管道密封安装方法制成的密封安装结构，其特点是，该密封结构包含：
分别设置于两根管道对接处的翻边，该一对翻边通过法兰连接；
夹设在两根管道翻边之间的密封条，并通过双面胶固定在两根管道中的一个的翻边上；密封条绕翻边一周设置并首尾交叉；密封条设置于所述法兰连接的螺栓相对于管道的内测。
上述密封条的内径与所述管道的内径一致。
本发明一种管道密封安装方法和现有技术的管道连接技术相比，其优点在于，本发明法兰连接之间夹设有密封条，通过挤压达到密封效果，该密封条采用聚四氟乙烯径向拉伸挤压制成，使得密封圈具有很好的延展性和抗拉性能，密封性能良好，并且密封圈具有很强的防腐性能，耐候性和耐磨性能，通过挤出模挤出可以做到无线长度，不会存在由于风管直径太大而无法完成开模的情况；
本发明密封连接方法简单，适用范围广，加工简单，操作方便快捷。

具体实施方式
以下结合附图，进一步说明本发明的具体实施例。
如图1所示，本发明公开一种管道密封安装方法，该方法包含以下步骤：
步骤1、在一对管道1对接处分别设置翻边11。如图2所示，可以在翻边11上靠近外边缘处绕翻边一周设有若干螺孔12，用于管道对接固定。
步骤2、如图3所示，密封条2一侧粘贴双面胶21。该密封条2采用聚四氟乙烯（PTFE）材料拉丝挤出工艺制成。
步骤3、密封条2通过双面胶21粘贴在两根对接管道1中任意一根管道的翻边11处，并取翻边的任意点为起点绕翻边一周设置。如图4所示，密封条绕所述管道翻边一周后，首尾交叉设置。
步骤4、密封条2首尾连接后，两根管道1翻边11对接，将密封条2夹设在两根管道的翻边12之间。
步骤5、如图5所示，两根管道1对接的翻边11处固定连接。
本实施例中，可以通过两根管道翻边11处的螺孔12对应设置，并串设紧固件13，从而两根管道1实现固定连接。密封条2设置于固定连接的紧固件13相对于管道的内侧。
通过紧固件13锁紧，使两根管道1固定连接处施加相向的作用力，对密封条2进行挤压，实现密封设置。
如图6所示，公开管道密封安装方法制成的密封安装结构的一种实施例。两根需要对接的管道1为直管，其对接处管道1设有翻边11。在两根管道1的翻边11上分别设有不等边卷制法兰13。不等边卷制法兰13上对应设有螺孔，螺栓3串设在该螺孔中，另一端通过螺帽4配合，实现两管道法兰连接。螺栓3与不等边卷制法兰13之间设有平垫5；螺帽4与不等边卷制法兰13之间设有平垫5和弹垫6。
在两根管道的翻边11之间夹设有密封条2，该密封条2通过双面胶固定在两根管道1中的一个的翻边11上。螺栓3相对螺帽旋进，对两个不等边卷制法兰13施加相向的力，使管道及其翻边11具有相向的作用力，对密封条2进行挤压，实现管道之间的密封连接。如图6所示，密封条2设置于螺栓3相对于管道的内测，以保证密封效果，同时密封条2的内径与管道1的内径一致，使连接后管道的连接处的内壁基本保持齐平，便于管道1内的流动，同时避免密封条2处留有残余物质而对密封条2产生腐蚀影响。
尽管本发明的内容已经通过上述优选实施例作了详细介绍，但应当认识到上述的描述不应被认为是对本发明的限制。在本领域技术人员阅读了上述内容后，对于本发明的多种修改和替代都将是显而易见的。因此，本发明的保护范围应由所附的权利要求来限定。
