Abstract

一种新型金属波纹管(螺旋波纹管)连接方法。本新型金属环型波纹管(螺旋波纹管)连接方法主要解决生产和使用中存在的安全引患（漏气漏液），提供一种全新管件连接方法，连接装置可以方便地对管件进行连接，使用安全方便、连接更加可靠、使用寿命周期长。本方法一种可以热熔材质的连接件接头（也可以通过注塑机加上其它工艺一次成型生产）。通过专用加热工具对连接装置和管件同时分别加热，加热到热熔材质所需温度时。把管件插入到热熔直孔接头内管相应的位置（限位）。再用专用工具夹在固定环上，施加压力使固定环受力，外径收紧变小迫使热熔料向管件外凹环内挤压，从而形成密封。同时把固定环把热熔管件与管件锁紧固定。

Description

一种热熔式金属环型波纹管(螺旋波纹管)连接方法
技术领域
金属环型波纹管(螺旋波纹管)领域。
背景技术
金属环型波纹管(螺旋波纹管)常被用来运输气体或其他的流体物质，金属环型波纹管(螺旋波纹管)在使用中往往要与其他结构进行连接，金属环型波纹管(螺旋波纹管)自身的安装固定也需要相应的连接装置。现有的金属环型波纹管(螺旋波纹管)连接起来不够方便，固定效果不太好，密封性能差，按装时易伤到管件，配件多且加工周期长。目前连接装置主要是由卡环、 内外螺母、密封橡垫等组合成，在生产上成本大、生产工序多、按装不方便，在使用过程中存在按装不到位、密封橡垫易损坏或老化所起漏气或水安全引患。因此结构简单、按装方便、使用安全的金属环型波纹管(螺旋波纹管)连接装置是必备的。
发明内容
本新型金属环型波纹管(螺旋波纹管)连接方法主要解决以上生产和使用存在的安全引患，提供一种全新金属环型波纹管(螺旋波纹管)连接方法，该金属环型波纹管(螺旋波纹管)连接装置可以方便地对管件进行连接，便于与其他结构的按装连接，使用安全方便、连接可靠、使用寿命周期长。本方法通过注塑机生产一种可以热熔材质的连接件接头。如图2一端嵌入金属螺纹接头一端直孔是可热熔管件，通过专用加热工具对直孔管件和金属环型波纹管(螺旋波纹管)同时分别同时加热，加热到热熔材质所需温度时。把金属环型波纹管(螺旋波纹管)插入到热熔直孔接头内管的底部同时用专用工具夹在固定环上（如附图4中的2号位置），施加力使金属固定环受力，内外径收紧变小迫使热熔料向金属波纹环型管(螺旋波纹管)凹环内挤压，从而形成密封。同时金属固环又把热熔管件与金属波纹环型管(螺旋波纹管)锁紧固定。按装好后效果如附图4，热熔管件加热前要先把金属固定环先按装好在热熔管件上一起加热。
金属固定环内外径收紧变小时把力传递到加热过的热熔直孔管件上，使管件受力变形缩小热熔料向凹环金属波纹环型管(螺旋波纹管)凹槽内挤压挤满热熔料包紧管件，这样就起到密封固定的作用，达到产品密封，按装方便，使用安全所需的目的，使用时间长，生产成本低环节少。
附图说明
附图1热熔连接管件，附图2金属波纹环型管，附图3金属固定环，附图4组装好的成品图。
