Technical Field
[0001] The invention relates to the technical field of pipeline connection, and in particular to a pipe fitting structure for an axial flow pump which can be quickly installed and disassembled. Background Art
[0002] An axial flow pump is a pump that transports liquid along the axial direction by the force exerted by the blades of a rotating impeller on the liquid. There are several types of pumps, including vertical, horizontal, inclined and cross-flow types.
[0003] During the pipe connection process of the axial flow pump, flanges are usually used. However, in this method, multiple fixing bolts and nuts need to be installed. In addition, the pipe needs to be positioned before installation, and the pipes using flanges are basically hard pipes, which are not easy to adjust, making the installation of the pipes more difficult. Summary of the invention

The bottom shell and the upper shell are fixed parts.
[0005] The first wedge-shaped member is fixedly connected to both sides of the interior of the bottom shell member, one side of the first wedge-shaped member is an inclined surface, and an opening for placing a pipe is reserved in the middle, and a second wedge-shaped member is arranged on one side of the first wedge-shaped member, and the structure of the second wedge-shaped member is consistent with that of the first wedge-shaped member, and the inclined surfaces of the first wedge-shaped member and the second wedge-shaped member cooperate to form a rectangular structure.
[0006] The middle part of the upper shell is threadedly connected with a screw rod, the lower end of the screw rod abuts against a pressure plate, and the pressure plate buckles the upper end of the second wedge-shaped piece. First, the two pipes are placed in the openings of the first wedge-shaped piece respectively, and then the second wedge is inserted between the first wedge and the flange at the pipe mouth, and finally the screw rod is rotated so that the pressure plate buckles the second wedge. After the first wedge and the second wedge are matched into a rectangular parallelepiped, the flanges of the two pipes are tightly fitted, thereby realizing the connection of the two pipes.
[0007] Preferably, the bottom shell comprises a first U-shaped body, the upper portion of which is provided with a first folded edge, the upper shell comprises a second U-shaped body, the lower inner side of which is provided with a second folded edge, and the lower end surface of the first folded edge is in contact with the upper end surface of the second folded edge. This structure allows the bottom shell and the upper shell to be separated, and the matching method realizes the vertical restriction of the bottom shell and the upper shell.
[0008] Preferably, the first U-shaped body is provided with ribs on both sides, and the first wedge-shaped member is accommodated between the two ribs, so as to limit the first wedge-shaped member from moving to one side.
[0009] Preferably, a threaded hole is provided in the middle of the upper end of the second U-shaped body, and the threaded hole cooperates with the screw rod to realize the threaded connection between the screw rod and the upper shell.
[0010] Preferably, a positioning groove is provided in the middle of the upper end of the pressing plate, and the lower end of the screw rod fits in the positioning groove, so as to prevent the screw rod and the pressing plate from sliding and dislocating.
[0011] Preferably, a rotating handle is inserted into the upper end of the screw rod, so that the screw rod can be rotated by hand, reducing the dependence on tools.
[0012] Preferably, a plurality of fixing bolts are inserted through the bottom of the bottom shell member, and the fixing bolts are threadedly connected to the first wedge-shaped member to fix the first wedge-shaped member.
[0013] The beneficial effects of the present invention are as follows:
[0014] 1. The flange connection method is eliminated, and the first wedge and the second wedge are used to clamp and force the pipeline to move axially. No positioning operation is required, which has the advantages of simple and fast connection.
[0015] 2. The present invention can realize bare-hand operation, reduce dependence on tools, and increase the speed of disassembly and assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figures 1 to 4 As shown, a pipe structure for an axial flow pump that can be quickly installed and disassembled includes a bottom shell 1 and an upper shell 2. The upper shell 2 is fastened and fixed to the upper end of the bottom shell 1. The bottom shell 1 and the upper shell 2 are two relatively fixed components.
[0025] The first wedge piece 4 is fixedly connected to both sides of the interior of the bottom shell 1. One side of the first wedge piece 4 is an inclined surface, and an opening for placing the pipe is reserved in the middle. A second wedge piece 5 is arranged on one side of the first wedge piece 4. The structure of the second wedge piece 5 is consistent with that of the first wedge piece 4, and the inclined surfaces of the first wedge piece 4 and the second wedge piece 5 cooperate to form a rectangular structure. When in use, the pipe is pre-placed at the opening of the first wedge piece 4, and then the second wedge piece 5 is inserted so that the second wedge piece 5 is located between the first wedge piece 4 and the flange at the pipe mouth. When the first wedge piece 4 and the second wedge piece 5 cooperate to form a rectangular parallelepiped, that is, the flanges of the two pipes are tightly fitted, then a tight connection of the two pipes is achieved.
[0026] The middle part of the upper shell 2 is threadedly connected with a screw rod 8, the lower end of the screw rod 8 presses against the pressure plate 6, and the pressure plate 6 is buckled on the upper end of the second wedge-shaped member 5. The screw rod 8 is rotated, and the screw 8 presses against the pressure plate 6, so that the pressure plate 6 presses the second wedge-shaped member 5, and the second wedge-shaped member 5 moves downward, realizing the counter-position connection of the pipeline.
[0027] The bottom shell 1 includes a first U-shaped body 12, the upper part of which is provided with a first folded edge 13, and the upper shell 2 includes a second U-shaped body 22, the lower inner side of which is provided with a second folded edge 21, and the lower end surface of the first folded edge 13 is in contact with the upper end surface of the second folded edge 21.
[0028] The first U-shaped body 12 is provided with ribs 11 on both sides, and the first wedge 4 is accommodated between the two ribs 11. The second wedge 4 of the bobbin slides.
[0029] A threaded hole 23 is provided in the middle of the upper end of the second U-shaped body 22, and the threaded hole 23 cooperates with the screw rod 8 to realize the threaded connection between the screw rod 8 and the upper shell 2
[0030] A positioning groove 7 is provided in the middle of the upper end of the pressing plate 6 , and the lower end of the screw rod 8 is fitted in the positioning groove 7 .
[0031] The upper end of the screw rod 8 is interspersed with a rotating handle 9. It is convenient to splice the pipelines by hand and reduce the dependence on tools.
[0032] A plurality of fixing bolts 3 are inserted through the bottom of the bottom shell 1 , and the fixing bolts 3 are threadedly connected to the first wedge-shaped member 4 , so as to fix the first wedge-shaped member 4 .
[0033] Working principle: When in use, two pipes with flanges at the ends are placed in the openings on the first wedge 4 in advance, and a sealing gasket is set between the two flanges. Then, the second wedge 5 is inserted into the gap between the first wedge 4 and the flange, and the first wedge 4 and the second wedge 5 are matched in a beveled manner, and a pressure plate 6 is placed on the upper end of the second wedge 5. Then, the upper shell 2 is moved along the axial direction of the pipe to the upper end of the bottom shell 1, so that the lower end face of the first folded edge 13 is located above the upper end face of the second folded edge 21. Finally, the screw 8 is used to rotate and connect with the upper shell 2, and as the screw 8 rotates, the lower end of the screw 8 is against the pressure plate 6, and the pressure plate 6 presses the second wedge 5, so that the first wedge 4 and the second wedge 5 are matched into a rectangular structure, so the two pipes are tightly connected.
