在进行井巷混凝土湿式喷射施工中,经常需要快速装拆管路,尤其是在发生堵管后,为防止混凝土滞留在机体和管路中发生凝固,需要快速排除堵管故障,要求所使用的管接头装拆快速,可靠。过去我们沿用螺纹联接的管接头,由于管子螺纹易被混凝土堵塞而使螺纹咬死,为了装拆而经常用锤敲打而造成严重的变形,使拆卸更为困难,严重影响了施工进度。为此,我们设计了一种卡销式快速管接头,其结构形式如图所示。本结构由接头外套1、橡胶密封垫2、O型密封圈3、U型卡销4、接头内套5等件组成,件6为被联接的胶管,用螺栓分别与接头内、外套联接。为
In the wet concrete construction of the shaft and culvert, it is often necessary to quickly assemble and disassemble the pipelines. In particular, after the pipe plugging occurs, in order to prevent the concrete from staying in the body and the pipelines to be solidified, it is required to quickly eliminate the plugging failure and require the used Fitting disassembly fast, reliable. In the past, we used threaded joints, because the pipe thread is easily blocked by concrete and make the thread biting, in order to demolition and often beat with a hammer caused serious deformation, making the demolition more difficult, seriously affecting the construction progress. To this end, we designed a snap-in quick connector, the structure shown in the figure. The structure is composed of a joint jacket 1, a rubber seal 2, an O-ring 3, a U-shaped bayonet 4, an inner sleeve 5 and the like, and a piece 6 is a hose which is connected and is respectively and respectively connected with an inner jacket and an outer jacket by a bolt. for
