Description

塑钢复合挠性配线管
所属技术领域
本实用新型涉及可弯曲的管子技术领域,更具体地说是涉及一种塑钢复合挠性管。
背景技术
目前广泛应用于石油、化工、食品、制药等行业的挠性配线管主要有两类,即塑胶类和金属类,由于材料及结构原因,前者阻燃性、耐老化性及强度较差,而后者耐酸、碱、盐腐蚀及柔性和绝缘性较差。
发明内容
本实用新型的目的就是要提供一种强度高、耐腐蚀、耐老化的塑钢复合挠性配线管。
本实用新型由外管和内管构成,其结构特点是内管为金属软管,外管为PVC塑料管,外管包覆在内管外面复合成一体。内管可采用镀锌金属软管,也可为镀铬金属软管或不锈钢软管。
本实用新型可采用一次性挤出法生产,工艺简单,生产效率高。内层管采用金属软管做骨架,形状稳定,强度高,弯曲半径大,在线路使用中可起到防止打火或燃烧的作用。外层复合软质PVC材料,结合力强,耐酸、碱、盐腐蚀,防水、防尘、防潮,柔性好,耐老化,阻燃、绝缘性能好。
附图说明
附图为本实用新型的纵向剖视图,示出了其整体结构。
具体实施方式
本实用新型塑钢复合挠性配线管由外管1和内管2构成,内管2采用镀锌金属软管,也可采用镀铬金属软管或不锈钢软管。外管1为PVC复合层,外管1包覆在内管2外面复合成一体。
塑钢复合的过程是将金属软管通过引入装置导入挤出机机头挤出复合塑料外层。常规型号采用一次挤出法复合,特殊要求的可采用二次挤出法或共挤法复合,最后经水冷却定型即可。
