[0018] Figure 2 It is a schematic diagram of the end packaging and fixing structure of the large-diameter ball valve packaging and fixing structure of the present utility model. DETAILED DESCRIPTION OF THE INVENTION

[0019] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Figures 1 to 2 Among them, a structure for packaging and fixing a large-diameter ball valve includes a valve end 100 and a support assembly. A rubber film 1 and a plywood 2 are sequentially provided at one end of the valve end 100, and connection holes 102 are provided in a circumferential uniform distribution. A stud 5 passes through the connection holes 102, and both ends of the stud 5 are press-fitted with a stud bushing 6. One end of the stud bushing 6 is sequentially press-fitted with a plywood 2, a washer 3 and a nut 4. The valve end 100 is provided with a connecting pipe 105, and the support assembly is provided with a support frame 8, and the support frame 8 is erected at the bottom end of the connecting pipe 105. The stud bushing 6 is provided with a through hole 602, and the through hole 602 is a threaded hole or a smooth hole.

[0021] One communication hole 103 is provided at the end of the valve 100. One valve water line 101 is provided at one end of the communication hole 103. The rubber film 1 is crimped to the valve water line 101, and the outer diameter of the rubber film 1 is larger than that of the valve water line 101. The specification of the communication hole 103 is DN200 - DN1000, and it can be DN200, DN500 or DN1000. A ring groove 104 is provided on the outer wall of the valve water line 101. The stud bushing 6 is provided with a flange 601, and the flange 601 is crimped to the ring groove 104. The stud bushing 6 presses and seals the connection hole 102 through the pressing of the stud 5.

[0022] The plywood 2 is provided with through holes 201 evenly distributed in the circumferential direction. The stud 5 passes through the through holes 201 and is locked by the nut 4. The end bolts of large - diameter valves are also particularly large, and the overall packaging cost is also very high. To save the packaging cost and ensure the stability of the packaging, the fasteners are reduced, that is, the stud 5. Each end of the stud 5 is provided with a plastic tie - strap 7, and the plastic tie - strap 7 abuts against the nut 4. The plastic tie - strap 7 prevents the nut from loosening during transportation.

[0023] A profiling groove 81 is provided at the top of the support frame 8, and the profiling groove 81 is crimped to the bottom end of the connecting pipe 105 through a rubber pad. The bottom end of the support frame 8 is fixedly connected with a support plate 9, and a U - shaped groove 91 is provided at the bottom end of the support plate 9. The U - shaped groove 91 improves the stability of the ball valve during transportation. A plurality of first screw holes 801 are provided at the bottom end of the support frame 8, and a plurality of second screw holes 901 are provided at the top end of the support plate 9. The first screw holes 801 and the second screw holes 901 are fixedly connected by bolts. The first screw holes 801 and the second screw holes 901 are both in one row or two rows and are arranged correspondingly. A first support plate 82 is provided at the middle position of the support frame 8, and a second support plate 83 is provided on each side of the first support plate 82. The first support plate 82 and the second support plate 83 improve the support strength of the support frame 8.

[0024] First, assemble the rubber film 1 against the valve water line. Then, insert the stud bushing 6 made of nylon rod into the threaded connection hole 102 at the end of the valve. Then, assemble the plywood 2 against the rubber film 1, insert the stud 5 and the washer 3, and then insert the nut 4. Finally, install the plastic tie - strap 7 between the stud 5 and the nut 4 to prevent bumps and looseness during transportation, and position the bottom end of the connecting pipe 105 using the support frame 8. This packaging structure is reasonably designed, without loosening, falling off and other phenomena, effectively avoiding the bumping of the end water line and the entry of foreign objects, and saving costs at the same time.

[0025] The above is only a specific application example of the present utility model, which does not constitute any limitation to the protection scope of the present utility model. Any technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of the protection of the rights of the present utility model.
