The utility model provides a corrugated pipe joint, which belongs to the technical field of pipe fittings. The utility model solves the problem that the existing corrugated pipe can not be cut freely according to the required length at the construction site. The corrugated pipe is a flexural metal bellows, which includes a movable joint and a joint sleeve connected with a movable joint. One end of the movable joint has a convex ring with external threads. The inner wall of the joint sleeve is fitted with the outer thread of the convex ring on the inner wall of the end of the convex ring, and the inner wall between the ends of the joint sleeve is protruded inward to form a step. The end of the step is provided with a gap, and the gap and the end of the convex ring are provided with a clamp ring which can restrict the movable joint and the axial movement of the joint sleeve, and the circle is located between the two adjacent ripples on the corrugated pipe, and the inner wall of the joint sleeve is provided with a number of elastic seals between the bellows and the inner wall of the joint sleeve, and some elastic seals are located on the bellows two. Between the adjacent ripples. The utility model has the advantages of free cutting at the construction site.
【技术实现步骤摘要】
一种波纹管接头
本技术属于管件
,涉及一种波纹管,特别涉及一种波纹管接头。
技术介绍
金属波纹管作为敏感组件、减震组件、补偿组件、密封组件、阀门组件及管路连接件,广泛应用于自动控制和测量仪表、机械工业、电力工业、交通运输、家装等领域,现有金属波纹管连接方式分为法兰连接、焊接、丝扣连接、快速接头连接,波纹管的长度尺寸一旦出厂就很难更改,在施工现场更无法根据所需长度进行自由裁剪。
技术实现思路
本技术的目的是针对现有技术中存在的上述问题,提供了一种可在施工现场自由裁剪的波纹管接头。本技术的目的可通过下列技术方案来实现:一种波纹管接头,该波纹管为可弯曲的金属波纹管,其特征在于,包括活动接头和与活动接头相连接的接头套,所述的活动接头一端具有带外螺纹的凸环,所述接头套靠近凸环一端的内壁上设有与凸环外螺纹相配合的内螺纹,所述接头套两端之间的内壁向内凸出形成台阶,且台阶的端部开设有缺口,所述缺口与凸环末端之间设有可限制活动接头和接头套轴向移动的卡圈,且卡圈位于波纹管上两相邻波纹之间,所述接头套的内壁与波纹管之间设有若干个弹性密封圈,且若干个弹性密封圈均位于波纹管上两相邻波纹之间。在上述的一种波纹管接头中,所述的弹性密封圈的数量为1-3个,且弹性密封圈均位于卡圈的左侧。在上述的一种波纹管接头中,所述的接头套远离活动接头的一端螺纹可为内螺纹或外螺纹。在上述的一种波纹管接头中,所述的卡圈由两个半圆环对接而成。与现有技术相比,本波纹管接头中接头套两端之间的内壁向内凸出形成台阶,且台阶的端部开设有缺口,所述缺口与凸环末端之间设有可限制活动接头和接头套轴向移动的卡圈,使波纹管在截 ...
