[0026] Under normal conditions, water will enter the water hole opened by the valve ball 1 38 after passing through the water inlet hole 17 made of rubber material. The left and right ends of the valve ball 1 38 are respectively in close contact with the water inlet hole 17 and the water outlet hole 14. At the same time, when a small flow rate is required each time the valve is opened, the locking bolt 37 can be disassembled first to release the limit on the threaded long rod 34, and then the extended threaded ring 33 can be pinched to rotate the threaded long rod 34, so that the threaded long rod 34 can be rotated and moved upward. When it moves to the top, the water hole opened by the valve ball 1 38 can leave the water inlet hole 17 and the water outlet hole 14, and the water hole with a smaller diameter opened by the valve ball 2 39 can re-connect the water inlet hole 17 and the water outlet hole 14.

At the same time, after the valve ball 2 39 rises, the bottom is in a suspended state, and then the lifting threaded rod 152 can be driven to rotate in the inner circle of the fixed bottom ring 151 by rotating the knob 154, so that the valve ball support plate 153 rotates and rises until it contacts the bottom of the valve ball 2 39, thereby improving the damping feeling and stability when the valve ball 2 39 is selected.

[0027] like Figure 4 , Figure 5 As shown, a fixed valve stem 341 is fixedly installed on the top of the threaded long rod 34, a telescopic valve stem 343 is slidably installed in the inner cavity of the fixed valve stem 341, a plurality of positioning holes 342 penetrating into the inner cavity are evenly opened on the top of the fixed valve stem 341, a semicircular elastic buckle 347 is arranged on the top of the telescopic valve stem 343, and the semicircular elastic buckle 347 is clamped with one of the plurality of positioning holes 342, a sliding rod 344 is fixedly installed on the front side of the inner wall of the fixed valve stem 341, a sliding compartment 346 is opened on the telescopic valve stem 343, and the rear end of the fixed valve stem 341 penetrates into the sliding compartment 34 6 and fixedly installed with a limit plate 345, the outer wall of the limit plate 345 overlaps with the inner wall of the sliding cabin 346, the water inlet mechanism 2 includes a water inlet pipe 21, the front end of the water inlet pipe 21 is fixedly connected with a water inlet flange 22, the rear side of the water inlet pipe 21 is fixedly connected with a water inlet connecting plate 23, the connecting plate 16 and the water inlet connecting plate 23 are both rectangularly arrayed with four front-to-back through bolt holes, the inner circles of the four bolt holes opened in the connecting plate 16 are all provided with bolts 161, and the four bolts 161 respectively penetrate the four bolt holes opened in the water inlet connecting plate 23 and are fixed with nuts;

[0028] When the rotation space of the fixed valve stem 341 is small, the telescopic valve stem 343 can be pressed against the inner cavity of the fixed valve stem 341, so that the semicircular elastic buckle 347 is compressed and moves toward the positioning hole 342 on the front side of the top of the fixed valve stem 341, and is snapped in one by one to achieve a shortening effect. At the same time, when it needs to be lengthened, it is only necessary to pull the telescopic valve stem 343 outward, so that the limiting plate 345 at the rear end of the sliding rod 344 slides in the sliding cabin 346, and the limiting plate 345 is used to resist the front side of the inner wall of the sliding cabin 346 to prevent the telescopic valve stem 343 from being pulled out, finally realizing the telescopic function of the fixed valve stem 341, which is convenient for adapting to different narrow environments, and the bolts 161 on one side of the four connecting plates 16 are removed by rotating, so that the water inlet connecting plate 23 is separated from the connecting plate 16, thereby facilitating disassembly and assembly.

[0029] The following is a detailed description of the working principle of the manual ball valve that is easy to lift and adjust.

[0030] like Figure 1-5As shown, when the liquid passes through, it will enter the inner cavity of the valve body control shell 11 from the water inlet mechanism 2 through the water inlet hole 17, and after passing through the inner cavity of the valve body control shell 11, it will enter the water outlet shell 12 from the rubber water outlet hole 14, and be discharged through the pipeline connected to the water outlet flange 13. Under normal conditions, the water source will enter the water through hole opened by the valve ball 38 after passing through the rubber water inlet hole 17. The left and right ends of the valve ball 38 are respectively tightly attached to the water inlet hole 17 and the water outlet hole 14. At the same time, when it is necessary to open the valve at a small flow rate each time, the locking bolt 37 can be removed first to release the limit on the threaded long rod 34. Then, the extended threaded ring 33 can be pinched to rotate the threaded long rod 34, so that the threaded long rod 34 can be rotated and moved upward. When it moves to the top, the water through hole opened by the valve ball 1 38 can leave the water inlet hole 17 and the water outlet hole 14, and the water through hole with a smaller diameter opened by the valve ball 2 39 can re-connect the water inlet hole 17 and the water outlet hole 14. At this time, the locking hole 35 at the lower rear side of the threaded long rod 34 is just aligned with the through hole 36 and penetrates. Then, the locking bolt 37 is realigned with the through hole 36 and rotated and tightened to complete the locking of the threaded long rod 34 and the extended threaded ring 33, and the extended threaded ring 33 is used to lock the threaded long rod 34. 3 and the fixed top ring 31, so as not to affect the rotation of the valve ball 39. At the same time, after the valve ball 39 rises, the bottom is in a suspended state, and the lifting threaded rod 152 can be driven to rotate in the inner circle of the fixed bottom ring 151 by rotating the knob 154, so that the valve ball supporting plate 153 rotates and rises until it abuts against the bottom of the valve ball 39, thereby improving the damping feeling and stability when the valve ball 39 is selected. When the rotation space of the fixed valve stem 341 is small, the telescopic valve stem 343 can be pressed against the inner cavity of the fixed valve stem 341, so that the semicircular elastic buckle 347 is compressed and moves toward the fixed valve stem. The positioning holes 342 on the front side of the top of 341 are moved and inserted one by one to achieve the shortening effect. When it needs to be lengthened, it is only necessary to pull the telescopic valve stem 343 outward, so that the limit plate 345 at the rear end of the slide rod 344 slides in the slide cabin 346, and the limit plate 345 is used to resist the front side of the inner wall of the slide cabin 346 to prevent the telescopic valve stem 343 from being pulled out, thereby finally realizing the telescopic function of the fixed valve stem 341, which is convenient for adapting to different narrow environments, and the bolts 161 on one side of the four connecting plates 16 are rotated and removed, so that the water inlet connecting plate 23 is separated from the connecting plate 16, thereby facilitating disassembly and assembly.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
