在各种管路上都要用很多管接头,以往连接管路的接头——连接螺母(又称活接头,见图1)都是用螺纹连接的,在装上或拆下时需要用扳手将螺纹一圈一圈地拧上去,或退下来,这样比较费时又费力。当松开接头时,管路里的介质——机油、乳化液、水等流体就流洒在设备上或地面上,使工作环境污秽。尤其对于一些需要经常装拆的管路来说,这些缺点就更突出了。 In a variety of pipelines have to use a lot of pipe joints, pipe joints in the past - connecting nut (also known as live joints, see Figure 1) are threaded connection, when installed or removed with a wrench The thread is screwed up or down in a circle, which is time-consuming and laborious. When the connector is released, the medium in the pipeline - oil, emulsion, water and other fluids on the device or the ground, so that the working environment filthy. Especially for some of the need for regular assembly and disassembly of the pipe, these shortcomings even more prominent.
