The utility model relates to the technical field of transition section pipeline connection, specifically is a kind of pipe network construction transition section pipeline connection structure, including transition pipe, the both sides of transition pipe are fixedly installed with connecting assembly, and the one end of transition pipe is fixedly installed with first pipeline body by connecting assembly, and the other end of transition pipe is fixedly installed with second pipeline body by connecting assembly, and connecting assembly includes two access pipes, and two the access pipe is fixedly installed at the both ends of transition pipe;The utility model installs transition pipe between two caliber different access pipes, when working, fluid passes through first pipeline body, and when fluid is guided under the conical inner wall of transition pipe, gradually increase the flow rate of fluid, avoid the flow rate and pressure fluctuation of excessive in short time, produce greater pressure to the connecting area between first pipeline body and second pipeline body, to protect the connecting area, improve the service life of connecting area.

The utility model belongs to electric fire range technical field discloses a kind of plasma generation assembly and electric fire, wherein, plasma generation assembly includes nozzle, plasma needle and cyclone tank;The nozzle is cylindrical structure, the cyclone tank is connected in the nozzle bottom end and is formed wind cavity with the nozzle inner side wall, one end of the plasma needle passes through the bottom wall of the cyclone tank and is located in the wind cavity;Several spiral grooves are equipped on the outer side wall of the cyclone tank, the spiral groove extends from the bottom wall of the cyclone tank to the upper wall of the cyclone tank, the wind cavity is communicated with outside by the spiral groove.Set up this spiral groove, wind can obtain higher acceleration in the process of flowing through spiral groove, the loss generated in the process that wind enters spiral groove is less, so that the flow and flow rate of wind that can enter the inside of wind cavity are all greater, more easily blow arc.
