DETAILED DESCRIPTION

[0018] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0019] Example: See Figure 1-3 , the main components of this case are: including a cylinder 1, on which a high adaptability structure is provided;

[0020] It should be noted that when the butterfly valve is used, the highly adaptable structure on the cylinder 1 can be used to connect pipes of different sizes.

[0021] In the specific implementation process, the high-adaptability structure includes: a valve plate 2, a valve shaft 3, a valve wheel 4, a drive assembly, a plurality of connecting columns 5, a pair of fixing plates 6, a plurality of arc-shaped fixing plates 7, a plurality of springs 8, a plurality of guide screws 9 and a plurality of nuts 10;

[0022] The valve plate 2 is installed in the cylinder 1, the valve shaft 3 passes through the cylinder 1 and is installed on the valve plate 2, the valve wheel 4 is connected to the valve shaft 3 through a driving assembly, a number of connecting columns 5 are respectively installed on the front wall and the rear wall of the cylinder 1, a pair of fixed disks 6 are installed on a number of connecting columns 5, a pair of fixed disks 6 are located in the front and rear of the cylinder 1, a number of arc-shaped fixed plates 7 are located in the pair of fixed disks 6, a number of springs 8 are installed between the pair of fixed disks 6 and the number of arc-shaped fixed plates 7, a pair of fixed disks 6 are provided with a number of through holes, a number of guide screws 9 are installed at their bottom ends on a number of arc-shaped fixed plates 7, a number of guide screws 9 are passed through the through holes provided on the pair of fixed disks 6, and a number of nuts 10 are screwed on the number of guide screws 9.

[0023] It should be noted that when the butterfly valve is needed, the pipes to be connected are placed in the middle of the arc-shaped fixing plates 7, and the springs 8 are released to drive the arc-shaped fixing plates 7 to be tightly attached to the external pipes. At this time, by adjusting the exposed length of the guide screws 9 outside the pair of fixing plates 6, the center of the external pipe and the cylinder 1 can be ensured to be the same. After the arc-shaped fixing plates 7 are fixed on the external pipes, the nuts 10 are screwed on the guide screws 9 to fix the guide screws 9, so that the cylinder 1 can be suitable for external pipes of different sizes, and when the fluid flows in the external pipes, the springs 8 can play a certain shock-absorbing role, thereby extending the use of the cylinder 1, and the valve wheel 4 is rotated by hand, and the valve shaft 3 is driven to rotate through the driving assembly, thereby driving the valve plate 2 to rotate for use.

[0024] In the specific implementation process, further, the driving assembly includes: a connecting block 11, an operating box 12, a turbine 13, a worm rack 14 and a worm 15;

[0025] The connecting block 11 passes through the valve shaft 3 and is installed on the upper wall of the cylinder 1. The operating box 12 passes through the valve shaft 3 and is installed on the connecting block 11. The turbine 13 is located in the operating box 12 and is installed on the valve shaft 3. The worm rack 14 is installed in the operating box 12. The worm rack 14 is located on the left side of the turbine 13. The worm 15 passes through the rear wall of the operating box 12 and is installed on the worm rack 14. The worm 15 is meshed with the turbine 13, and the valve wheel 4 is installed on the worm 15.

[0026] It should be noted that when it is necessary to drive the valve shaft 3 and the valve plate 2 to rotate, the valve wheel 4 is held and rotated, and the rotation of the valve wheel 4 drives the worm 15 installed on the valve wheel 4 to rotate. The worm 15 is installed in the operating box 12 through the worm rack 14. Since the worm 15 and the turbine 13 are meshed, the turbine 13 is driven to rotate, which drives the valve shaft 3 to rotate, thereby driving the valve plate 2 to rotate.

[0027] In the specific implementation process, further, the valve wheel 4 is provided with anti-skid grooves 16 for preventing skidding.

[0028] In the specific implementation process, further, a fixing seat 17 for fixing is provided under the cylinder 1.
