Abstract
The utility model relates to a connecting pipe for a water supply and drainage system in industrial and civil construction. The utility model is composed of a casing head 1, a straight pipe 2 and threads 3, wherein, the casing head 1 and the straight pipe 2 are split into two parts; the lower part of the casing head 1 is provided with internal threads 3; the casing head 1 and the straight pipe 2 are connected by the threads 3. The utility model has the advantages that the casing head of a pipe socket and the straight pipe section are two parts, and are connected by taper pipe threads or pipe threads, which is suitable for replacement and repair of perforation of socket pipelines for cast iron and newly build of water feeding and sewer pipeline engineering; the installation is convenient; the time is saved; the labor is saved; the sealing performance is good.
Description
The utility model relates to the connecting tube of forming a connecting link of supply and drain water system in a kind of worker China Democratic National Construction Association.
At present, the interface section of used water-feeding drainaging line is a card edge type in the building, the pipe end that is about to osculum directly inserts the big opening end of another root pipe, use cement seal again, its casing head and straight-tube portion are one, though simple in structure, use rather effort, leak easily, and time-consuming.
The purpose of this utility model is to provide the connecting tube of forming a connecting link of a kind of casing head and straight tube split, simple in structure and good airproof performance.
The utility model is achieved in that by casing head 1, straight tube 2, screw thread 3 to be formed, and casing head 1 is split two-part with straight tube 2, and internal thread 3 is arranged at casing head 1 bottom, and casing head 1 is connected by screw thread 3 with straight tube 2.
Screw thread 3 can be the inclined-plane, also can face directly.
The diameter of 3 mouthfuls of ends of screw thread is greater than straight tube 2 bottom tab diameters.
Advantage of the present utility model is: bellmouth casing head and straight length are two-part, connect with taper pipe thread or pipe thread, be suitable for Replacement and Repair and newly-built upper and lower water pipeline engineering that cast iron is accepted the pipeline perforation, broken, simple installation, time saving and energy saving, and good airproof performance.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
The utility model is made up of casing head 1, straight tube 2, screw thread 3, and casing head 1 is split two-part with straight tube 2, and internal thread 3 is arranged at casing head 1 bottom, and casing head 1 is connected by screw thread 3 with straight tube 2.
Screw thread 3 can be the inclined-plane, also can face directly.
The diameter of 3 mouthfuls of ends of screw thread is greater than straight tube 2 bottom tab diameters.
To connect by taper pipe thread or straight pipe thread with casing head 1 between the two tubes, with the pointed with cement mortar sealing, both finished the connection of pipeline again.
