本实用新型涉及管道安装封闭塞。 The present invention relates to pipe installation closure.
过去公用与民用建筑施工过程中管道安装时，对安装管道中途预留管孔（座）封闭采用的办法不一，使其封闭不严密，特别是排水管道孔（座）上的封闭物（砖、灰等），可任意拿掉，施工时的杂物往往容易进入管道，造成堵塞现象，且不易被发现，这样在建筑物投入使用时，由于管路堵塞不能使水流通，造成重新修理现象，给使用者带来麻烦并造成人力、财力浪费，是基建行业普遍存在的通病，至今无很好办法解决。 Past public and civil construction during pipeline installation, the pipe installation hole midway reservation (seat) is closed approach adopted varies, it is not tightly closed, the closure (in particular bricks drains holes (base) , ash, etc.), can be arbitrarily removed, when construction debris often easy access to the pipeline, causing clogging, and not easily found, so that when the building put into use, because the pipe blockage can not make the water flow, resulting in the phenomenon of re-repair , to bring users the trouble and cause human, financial waste, is widespread infrastructure industry a common problem, so far no good solution.
本实用新型目的是提供一种在安装管道中途预留孔（座）上封闭的管孔封闭塞。 The present invention aims to provide a closed conduit mounted on the intermediate prepared hole (seat) hole closing plug.
本实用新型是由内螺纹螺母、封闭塞体、膨胀塞组成，由再生橡胶或金属加工而成的封闭塞体的中心设置有螺杆，螺杆的下端加工有锥体形膨胀塞，膨胀塞外侧的封闭塞加工成与之相配合的锥体形状。 The present invention is an internally threaded nut, the closure plug body, composed of the expansion plug, the central processing or recycled rubber obtained by a metal closure body is provided with a screw which is machined with conical lower end expansion plug, dowel outer closure Saiga processed into a conical shape mating therewith.
本实用新型具有结构简单、安装使用方便、对管孔封闭效果好、寿命长、经济和社会效益明显等特点。 The present invention has simple structure, easy installation, good effect of blocking holes, long life, economic and social benefit and so on.

下面结合附图对本实用新型作进一步描述，本实用新型是安装管道中途预留管孔（座）封闭使用，封闭塞体1加工成与管道相同的圆柱体形状，材质采用再生橡胶或金属等，封闭塞体的中心设置有螺杆2，螺杆的上端与内螺纹螺母4相连，螺杆的下端加工有锥体形膨胀塞3，封闭塞体的上部外侧边缘加工有外沿，便于封闭塞体安装时与管道相配合，封闭塞体的下部与膨胀塞配合处加工成锥体形状。 DRAWINGS The present invention is further described for the present invention is mounted midway reservation hole pipe (seat) is closed using the closure plug body is processed into a cylindrical shape and the same duct using recycled rubber material or a metal or the like, center of the closure plug body is provided, connected to the upper end of the inner screw thread of the nut 4, the lower end of the screw machined with conical dowel 3, the outer edge of the closure plug body has an upper machining the outer edge, to facilitate the closure body is mounted with the screw 2 conduit cooperates with the lower portion of the expansion plug engages the closure plug body is processed into the shape of a cone. 本实用新型的安装及使用原理是这样的，城市公用与民用建筑时，在施工过程中，将本实用新型安装在管道中途预留孔（座）内，用活搬手将内螺纹螺母旋紧，这时通过螺杆将其下端的锥体形膨胀塞提起，膨胀塞位于封闭塞体下部的锥体形状槽内，封闭塞体膨胀，将管路密封住，施工过程中的泥土等不能进入管道造成堵塞，当施工完后投入使用时，将管孔封闭塞卸下即可。 The present invention installed and used principle is such that, when the city public and civil buildings, in the construction process, the present invention is installed in the middle of the pipe preformed holes (seat), with live wrench tightening the nut internal thread since, at this time the lower end thereof by a screw of conical expansion Sethi, plug the lower portion of the dowel body in the closed conical shape groove, the closure plug body expands to seal the tubing, the construction process of the pipeline caused by mud can not enter jam, when construction finished and put into use, the hole closed to remove the plug.
