This creation is about a flange structure improvement, especially a flange structure improvement of a coupling pump.

At present, the inlet and outlet ends of the shaft pump, or the joints of other pipe fittings, are mostly flanged as a connecting piece, so that the different pipes can be connected to each other, and the hole diameter of the flange must be connected to the connected pipe. The hole diameter specifications are the same. Take the inlet and outlet ends of the coupling pump as an example. The diameter of the flange connected to the water inlet end must be the same as the diameter of the inlet end, and the diameter of the flange connected to the water outlet must be It has the same pore diameter as its outlet.

By the above, the size specifications of the inlet flange 2 and the outlet flange 3 of the conventional coupling pump 1 are very small. If the outlet end 5 of the coupling pump 1 is to be connected to the larger diameter pipe 6, the outlet The nozzle flange 3 and the flange 7 of the pipe 6 must be connected by an adapter pipe 8, wherein the diameter of one end of the adapter pipe 8 is the same as the first water outlet hole 3a of the water outlet flange 3, and The aperture of the other end of the transfer tube 8 is the same as the flange 7 of the pipeline 6, so that the water outlet end 5 can be smoothly connected with the pipeline 6 of the larger aperture, as shown in FIG. 3, and vice versa, if the coupling pump 1 is The water inlet end 4 needs to be connected to another pipeline of a larger aperture, and the connection pipe 9 is required to be connected to each other. Therefore, the piping of the water inlet end 4 and the water outlet end 5 of the coupling pump 1 is known. The process is very cumbersome and time consuming, but it is very inconvenient.

In order to solve the above problems, the present invention provides a flange structure improvement of the coupling pump, wherein the diameters of the inlet flange and the outlet flange are unchanged compared with the conventional ones, and the inlet flange and the outlet flange are added.
