Abstract
The utility model discloses a pipeline communicating part which comprises a pipe fitting body and a sleeve. A lateral pipe part protruding outwards is formed on the lateral wall of the pipe fitting body. External threads are arranged on the outer wall of the lateral pipe part; internal threads matched with the external threads are arranged on the inner wall of the sleeve; and the sleeve is sleevedon the lateral pipe part and is in threaded connection with the lateral pipe part. The pipeline communicating part can be processed by using matched pipe products with different pressure resistant grade requirements; and different national code requirements can be achieved through changing the internal diameters of the pipe fitting body and the sleeve without opening steel moulds, so that the manufacturing cost can be greatly reduced; and meanwhile, the pipeline communicating part has good high-temperature resistant and high-voltage resistant performance.
Description
Technical field
The utility model relates to the pipeline connectedness, especially a kind of pipeline connectedness that adopts plastic cement material.
Background technique
The tubing bore of all various plastic cement materials can be accomplished very large size at present, but for necessary supporting large diameter pipeline connectedness such as threeway, four-way all can't come machine shaping through injector again after opening steel or aluminium matter mould earlier, main cause has: the large scale threeway, the four-way part specifications is of a great variety, and large-scale part jetting mold die sinking expense is too high, big machine expense of capacity injector own and support expense investment are too big, add the not anti-long high-temperature baking of some plastic material itself, so traditional large-sized threeway, the pipeline connectedness of all size sizes such as four-way all is to process with manual, its course of working is shown in Figure 1A to Fig. 1 C: promptly will saw a V-arrangement recess 81 by main pipe body 8 central authorities that plastic cement tubing is made earlier, a V-arrangement tang 91 with main pipe body parts V-arrangement recess same size is also sawed in the bottom of the intubate 9 that will be made by plastic cement tubing simultaneously, use then with the welding rod of material 100 welding of V-arrangement seam, add special resin 10 (FRP) with glass fiber sheets again after having welded the V-shaped part and the neighboring area of above welding coated.There are following shortcoming in the large scale threeway that above traditional-handwork is made into, four-way pipeline connectedness: body and side pipe are too little because of bonding area, so combination force is firm inadequately, pull resistance and crushing resistance all a little less than, and sealing effect is not good.In addition, the FRP material is different with the plastic cement material thermal expansion coefficient of main pipe body and side pipe, so under long-term accumulated temperature situation, can be separated from mutually, the coating profile of FRP is very not attractive in appearance simultaneously.Based on the above fact, large-sized plastic cement pipeline connectedness that traditional-handwork is made all can only be used for the pipe-line system of low-pressure and low temperature as threeway, four-way.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pipeline connectedness of being convenient to make and have good high temperature resistant and high voltage performance.
The technological scheme that the utility model adopted is: a kind of pipeline connectedness, comprise pipe fitting body and sleeve pipe, and on the sidewall of pipe fitting body, be formed with the side pipe portion of outside protrusion; Wherein, the outer wall of side pipe portion is provided with outside thread, and the inwall of sleeve pipe is provided with the internal thread that is complementary with this outside thread, and casing pipe sleeve is located in the side pipe portion, and is threaded with side pipe portion.
Above-mentioned pipeline connectedness wherein, is laid with glue on outside thread and internal thread.
Above-mentioned pipeline connectedness, wherein, the free end of side pipe portion and the weldering of the inwall of sleeve pipe connect.
Above-mentioned pipeline connectedness, wherein, sleeve pipe connects with respect to the end wall and the weldering of pipe fitting body of pipe fitting body one end.
The utility model has the advantages that:
1. the utility model can be processed with the tubing that is complementary the pipe joint of different compression resistance class requirements, for the country variant code requirement, the internal diameter that can change pipe fitting body and sleeve pipe is finished, and need not out punching block, thereby can reduce manufacture cost greatly;
2. the wall ratio tube wall thickness at pipe fitting body of the present utility model and the sleeve pipe place of mutually combining has increased more than 70%, so compression resistance has herein surpassed the compression resistance of tubing;
3. the total area ratio traditional approach at pipe fitting body of the present utility model and thimble joint place is big tens of times, add the chemical force of the mechanical force that is threaded, glue special and with the weld force of material welding rod, so can satisfy technical grade maximum pressure class requirement fully, and can not leak, can not throw off;
4. finished product of the present utility model is made by identical material, has identical thermal expansion coefficient, therefore can tolerate the variation significantly of the temperature difference.
