[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model provides Figure 1-5 The high platform ball valve with a handle limit structure shown in the figure comprises a valve body 1; used for conveying medium fluid;

[0029] The connecting frame 2 is fixed on the top of the valve body 1. The connecting frame 2 is provided with thread grooves 3 on all four sides. The upper and lower surfaces of the connecting frame 2 are provided with first limit grooves 4. The connecting frame 2 is movably connected with a transmission rod 5. A limit frame 6 is installed inside the connecting frame 2. The limit frame 6 is used for limiting the rotation of the handle. The two sides of the limit frame 6 are movably connected with first bolts 7. The upper and lower surfaces of the limit frame 6 are provided with second limit grooves 8.

[0030] The fixing rod 9 is fixed to the upper end of the transmission rod 5 and is used to assemble the handle. The fixing rod 9 is respectively provided with a limit plate 10 and a gasket 11 on the outside.

[0031] The handle 12 is sleeved on the outside of the fixed rod 9. The handle 12 is movably connected to the inside of the handle 12. A pull ring 16 is fixedly installed on the upper end of the movable rod 15. Fixed blocks 17 are fixedly installed on both sides of the outside of the movable rod 15. A spring 18 is arranged on the outside of the movable rod 15. First, it is sleeved on the connecting frame 2 through the limit frame 6, and the two are fixed by the first bolt 7. Then the limit plate 10 and the gasket 11 are sleeved on the fixed rod 9, and then the handle 12 is sleeved on the fixed rod 9. When the handle 12 drives the fixed rod 9 to rotate, the chamfered shape of the limit plate 10 is used to touch the inner side of the limit frame 6 during the rotation process to block it and limit the handle 12. The limited handle 12 is extended and retracted by the rebound effect of the spring 18 outside the movable rod 15, and the movable rod 15 is extended and retracted into the first limit groove 4 or the second limit groove 8 to limit and lock the handle 12, which can prevent other people from touching the handle 12 and causing the valve body 1 to open or close.

[0032] like Figure 1 and Figure 2 As shown, the limit frame 6 is threadedly connected to the connecting frame 2 through a first bolt 7. The first bolt 7 is a hexagonal screw. The first bolt 7 is used to limit the installation between the limit frame 6 and the connecting frame 2 so as to limit the rotation of the limit plate 10 later.

[0033] like Figure 3 and Figure 4 As shown, a rubber sleeve 13 is provided on the outside of one side of the handle 12, and a screw 14 passes through one side of the handle 12. The rubber sleeve 13 can effectively avoid electric shock.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing rod 9 is a square structure, the internal dimensions of the handle 12 are consistent with the external dimensions of the fixing rod 9, and the handle 12 is fixedly connected to the fixing rod 9 by a screw 14. The internal shape of the handle 12 is the same as the external shape of the fixing rod 9, which facilitates installation and enhances the firmness of both. Then, the handle 12 is tightened and fixed on the fixing rod 9 by the screw 14.

[0035] like Figure 1 and Figure 5 As shown, a first flange 19 is fixedly connected to one side of the valve body 1, and second bolts 20 penetrate the four sides of the first flange 19. The connection between the first flange 19 and the valve body 1 can facilitate the maintenance of the internal ball valve by the staff.

[0036] like Figure 1 and Figure 5 As shown, the other side of the valve body 1 and one side of the first flange 19 are respectively fixedly installed with a second flange 21, the inner surface of the second flange 21 is provided with a sealing groove 22, and the inside of the sealing groove 22 is movably connected with a sealing ring 23. The second flanges 21 on both sides of the valve body 1 are arranged to facilitate connection with other equipment, and the sealing ring 23 arranged inside the second flange 21 serves to enhance the sealing effect.

[0037] The working principle of the utility model is as follows: first, the limiting frame 6 is sleeved into the connecting frame 2 on the valve body 1, and then the first bolt 7 is used to penetrate both sides of the limiting frame 6 and the connecting frame 2, and then the first bolt 7 is tightened to limit and fix the two, and then the limiting plate 10 and the gasket 11 are sleeved and pressed on the top of the fixing rod 9, and then the handle 12 is sleeved on the outside of the fixing rod 9. After being sleeved outside the fixing rod 9, the screw 14 on the front side of the handle 12 is tightened to fix the handle 12. After assembly, the valve body 1 is placed in the designated installation position, and then the sealing ring 23 is sleeved inside the two sets of second flanges 21, and then the second flanges 21 are threadedly connected to the equipment connecting pipes on both sides. After the connection is completed, when the fluid starts to be transported normally, the handle 12 is held and rotated, and the fixing rod 9, the gasket 11 and the internal ball are driven during the rotation process. The valve is designed to be opened by the user, and the limiting piece 10 is chamfered, so that it can block the inner side of the limiting frame 6 when it touches it during the rotation, and the handle 12 is limited in the open state. At this time, the movable rod 15 is retracted into the second limiting groove 8 inside the limiting frame 6 by the rebound effect of the spring 18, so that the handle 12 is limited. In this way, there is no need to worry about other people accidentally touching it and causing the handle 12 to rotate. When the ball valve needs to be closed, the pull ring 16 is pulled to retract the movable rod 15, and the spring 18 is compacted by the fixed block 17 outside the movable rod 15. Then the handle 12 is turned to close the ball valve. When the ball valve is closed, the pull ring 16 is released, and the movable rod 15 rebounds and enters the first limiting groove 4 on the connecting frame 2 for limiting. In this way, the use process of the high platform ball valve with a handle limiting structure is completed.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
