specific Embodiment approach 1
[0005] Specific implementation mode one: the following combination figure 1 This embodiment will be specifically described. This embodiment is composed of a plastic casing 1 and connecting pipe fittings 2 arranged on both sides of the casing 1. The casing 1 and the connecting pipe fittings 2 communicate with each other and are integrated by injection molding. One end of the connecting pipe fitting 2 is buried in the solid tissue of the casing 1, and the other end of the connecting pipe fitting 2 is provided with an external thread or an internal thread. With such an arrangement, the connection between the connecting pipe piece 2 and the casing 1 is relatively firm.
specific Embodiment approach 2
[0006] Specific implementation mode two: the following combination figure 2 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that it also includes an embedded plate 3 , the embedded plate 3 made of metal is contained in the solid tissue of the shell 1 and is fixedly connected with the connecting pipe 2 . The casing of the flow meter arranged in this way has higher strength, and in addition, the embedded plate 3 does not contact liquid or gas, and the heat deformation is also small.
specific Embodiment approach 3
[0007] Embodiment 3: The difference between this embodiment and Embodiment 1 or Embodiment 2 is that the material of the shell 1 is polypropylene random copolymer, English abbreviation (PPR).
