| titleOfInvention | Flecxible Joint Pipe for CPVC Firefighting Branch Piping and Manufacturing Method Thereof |
| abstract | The expansion and contraction pipe of the present invention is installed between a branch pipe for a sprinkler and a reducing elbow for installing a sprinkler head, which serves to ease the piping work and the stress generated in the sprinkler pipe, A stretch pipe for canceling the generated stress; And an adapter connected to one end of the expansion pipe to couple the branch pipe and the expansion and contraction pipe. The adapter is made of a CPVC material by injection molding. The branch pipe is inserted into the adapter, A fixing jaw formed into a ring shape so that the adapter is narrower than the hollow of the branch pipe insertion portion and the adapter is fixed between the terminal portion and the bulging portion; A first O-ring mounting jaw to be installed on the inner side of the expansion pipe, and a flexible pipe mounting part in which the expansion / contraction pipe is inserted and the hollow in which the second O-ring and the third O-ring are installed, Step 1; A second step of manufacturing the adapter; A third step of manufacturing the flare nut; A fourth step of preparing the first O-ring, the second O-ring, and the third O-ring; A fifth step of forming the first ring groove and the second ring groove by grooving the stretch pipe with a grooving machine; A sixth step of coupling the adapter to one end of the expansion pipe; A seventh step of coupling the flare nut to the other end of the expansion pipe; And an eighth step of finally examining the finished product. According to the stretch piping for CPVC branch piping of the present invention and the method of manufacturing the same, the extensible pipe is made of stainless steel and the adapter is made of CPVC, so that when the branch pipe of the sprinkler is used with CPVC material, It is possible to reduce the construction cost without deteriorating the function of the expansion and contraction pipe. It is possible to prevent the leakage from the first o-ring at first between the expansion pipe and the adapter and to prevent the leakage at the second o-ring and the third o- The reliability of the piping for preventing leakage is improved and the end portion and the bulging portion are formed in the expansion and contraction pipe to improve the durability of the pipe by increasing the coupling force between the expansion pipe and the adapter. |
