[0027] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with examples. The schematic embodiment and its description of the utility model are only used to explain the utility model, and do not limit the utility model.
[0028] Example 1:
[0029] like Figures 1-6 As shown, a pipe fitting connection device for a CBF pipe includes a connection device body 1. One end face of the connection device body 1 is provided with a protruding annular structure 2, and the other end face of the connection device body 1 is provided with an outer annular body 3 and an inner annular body 5 located inside the outer annular body 3. An annular groove 4 is formed between the outer annular body 3 and the inner annular body 5. A rubber sealing gasket is installed in the annular groove 4. The top of the rubber sealing gasket in the annular groove 4 is lower than the top of the inner annular body 5. One side of the connection device body 1 is welded to the pipe fitting through the protruding annular structure, and the other side of the connection device body 1 is detachably connected to the CBF pipe under the guidance of the annular groove 4 formed by the outer annular body 3 and the inner annular body 5 and the rubber sealing gasket installed in the annular groove 4.
[0030] In this embodiment, the connecting device body 1, the protruding annular structure 2, the outer annular body 3, and the inner annular body 5 are integrally molded structures. In the specific key connecting device product structure of CBF pipelines, the inner annular body 5 and the outer annular body 3 have the same depth. The depth of the inner annular body 5 may also be greater than the depth of the outer annular body 3. Here, the depth refers to the depth from the free end face of the inner annular body 5 and the outer annular body 3 to the bottom surface.
[0031] Specifically, the connecting device body 1 has a circular structure, which can be understood as a disc-shaped structure. A protruding annular structure 2 is provided on one side of the connecting device body 1 where it connects to the pipe fitting. The connecting device body 1 and the protruding annular structure 2 are integrally formed. To facilitate connection with the pipe fitting, the cross-section of the protruding annular structure 2 is circular, specifically a hollow cylindrical structure. Furthermore, the outer diameter of the protruding annular structure 2 is smaller than the diameter of the connecting device body 1. Since the connecting device body 1 has a circular structure, its diameter is its outer diameter, which can also be understood as the maximum diameter. During connection, if the pipe fitting, such as a polyethylene tee, can be directly heat-fused to the free end of the protruding annular structure 2, then the connection between one end of the pipe fitting connecting device and the pipe fitting is completed. In this embodiment, the pipe fitting can be any one of a polyethylene tee or a polyethylene elbow, or other pipe fitting structures of unrestricted materials.
[0032] The rubber sealing gasket installed in the circular groove 4 is in close contact with the inner surface of the circular groove 4, and the ring width of the circular groove 4 is greater than the wall thickness of the rubber sealing gasket. In the process of connecting with the CBF composite pipe, the rubber sealing gasket is in close contact with the inner surface of the circular groove 4, and the contact force is enhanced in the form of clearance fit, so that the rubber sealing gasket is difficult to slide out of the circular groove 4. The maximum diameter of the outer circular body 3 is the same as the diameter of the connecting device body 1, and the wall thickness of the CBF composite pipe is the same as the ring width of the circular groove 4.
[0033] In the process of connecting with the CBF composite pipe, the area between the top of the rubber sealing gasket and the inner circular body 5 can guide the CBF composite pipe into the area of the circular groove 4, and the end surface of the CBF composite pipe is in close contact with the upper area of the circular groove 4, so as to achieve the sealing effect on the end surface of the CBF composite pipe. The whole installation process is simple, and the installation is quickly realized, and the sealing effect of the connection is good.
[0034] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above description is only a specific embodiment of the utility model, and is not used to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
