Embodiment 1
[0026] This embodiment provides a pressure controllable pipeline pressure regulating device, as shown in Figure 1-3, wherein,
[0027] The upper passing water body 101 and the lower passing water body 102 are formed by connecting a cylinder with a large diameter and a small diameter. The end with a large diameter forms an opening, and the ends with a large diameter of the upper passing water body 101 and the lower passing water body 102 are connected to each other to form a complete tower. body, the overall shape is narrow up and down and wide in the middle, and the upper and lower water passing bodies 102 are connected by flanges, which is convenient for disassembly and assembly, and at the same time, the large middle diameter can speed up the water passing speed and improve the operating efficiency of the device. The upper water body 101 is provided with a first interface 101a, the lower water body 102 is provided with a second interface 102a, the second interface 102a is an ...
Embodiment 2
[0033] This embodiment is different from the previous embodiment in that, as Figure 4-5 As shown, among them,
[0034]The pressure regulating module 200 includes a fixing piece 203 connected below the connecting shaft 202. The fixing piece 203 is provided with several blades 204 evenly distributed along the circumference. In this embodiment, there are 6 blades 204 arranged around the outside of the fixing piece 203. And the blades 204 are planar, and the fan angle of each blade 204 is 60°. When all the blades 204 are on the same plane, the blades 204 and the fixing member 203 can just block the guide tube 103 .
[0035] Further, the fixing member 203 is provided with an annular groove 203a, the annular groove 203a is located outside the connecting shaft 202, the annular groove 203a is coaxial with the connecting shaft 202, the fixing member 203 is provided with a plurality of insertion holes 203b, and the blade 204 is provided with Insertion rod 204b, the insertion rod 204b ...
