小口径(DG15～50)管件、阀门和水表与管子的传统连接方法是在管子上套丝、缠麻和刷白铅油(或缠胶带)通过螺纹接通。这种连接方式由于在管子上套丝而使管壁减薄1/3,出现的锈蚀问题也严重影响着管子的使用寿命。另外,安装时,劳动强度大,工效低,跑、冒、滴、漏时有发生。为此,本人设计、试制成功一种速接管件、阀门和水表系列新产品,已获得国家专利(ZL92234318.7),现介绍如下。1 工作原理速接管件、阀门和水表是在传统产品的基础上将连接部分进行了改进设计、主要是利用螺旋副的轴向移动挤压柔性材料制作的卡套达到密封防漏和卡紧光管(管子上不套丝扣)的目的。
Small diameter (DG15 ~ 50) pipe fittings, valves and water meters with the traditional method of connecting pipes in the pipe threading, Ma Wan and white lead oil (or wrapped tape) through the threaded connection. This connection due to pipe threading and pipe wall thinning 1/3, the rust problem also has a serious impact on the life of the tube. In addition, the installation, the labor-intensive, low efficiency, running, running, dripping, leakage occurred from time to time. To this end, I design, trial success a quick access tube, valve and water meter series of new products, has obtained national patent (ZL92234318.7), are described below. 1 Working principle Quick-connect fittings, valves and water meters are based on the traditional products will be part of the connection to improve the design, the main is the use of screw-driven axial movement of the extrusion of flexible materials to achieve the seal leak-proof and clamping light Tube (tube does not set Threaded) purposes.
