DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model discloses an adjustable valve structure, including a valve body 1, the valve body 1 including a valve body 11, a round platform 12 is arranged on the top of the valve body 11, a valve stem 17 is arranged inside the round platform 12, the bottom end of the valve stem 17 extends to the inside of the valve body 11 and is provided with a valve ball, a handle 2 is movably connected to the top of the valve stem 17, a button 21 is movably embedded on the top of the handle 2, a driving groove 22 is opened inside the handle 2, a clamping rod 23 driven by the button 21 is movably arranged in the driving groove 22, and one end of the clamping rod 23 is clamped with the top of the valve stem 17.

[0024] Specifically, a clamping nut 16 is provided inside the truncated cone 12, and the top of the valve stem 17 passes through the clamping nut 16 and is provided with a square steel 18. The square steel 18 is provided with slots 181 around it. The arrangement of the slots 181 around the square steel 18 facilitates the user to select the installation direction of the handle 2. When customers install conventional ball valve products in some locations with smaller spaces, due to the obstruction of other pipes or objects around, the handle 2 cannot be fully opened or fully closed after the ball valve is installed. The disassembly can be completed by pressing the button 21 to lift the handle 2. The operation is simple and quick, and it is conducive to adjusting the direction of the handle 2.

[0025] Specifically, a sealing ring 19 is disposed inside the valve body 11 and is sleeved with the surface of the valve stem 17 . The provision of the sealing ring 19 ensures the sealing performance of the valve stem 17 .

[0026] Specifically, one end of the valve body 11 is provided with a flange 13, and the other end is provided with a flange 2 14. The internal thread of the flange 2 14 is sleeved with an inner plug 15. A plurality of reinforcing ribs 111 are provided between the two ends of the valve body 11 and the flange 1 13 and the flange 2 14. The provision of the reinforcing ribs 111 ensures the structural strength of the flange 1 13 and the flange 2 14.

[0027] Specifically, the number of the driving slots 22 is at least two and the two driving slots 22 are symmetrically arranged.

[0028] Specifically, the bottom end of the clamping rod 23 is L-shaped and extends to the inside of the clamping slot 181. The top of the clamping rod 23 is provided with an inclined block 24. The bottom circle of the button 21 is provided with an inclined edge portion 25. The inclined edge portion 25 contacts the inclined surface of one side of the inclined block 24. When the button 21 is pressed down, the inclined edge portion 25 of the bottom circle of the button 21 descends and contacts the inclined surface of the inclined block 24, so that the inclined block 24 is resisted and translates. The translation of the inclined block 24 drives the clamping rod 23 to move out of the inside of the clamping slot 181, and the handle 2 can be pulled out vertically. The groove shape inside the handle 2 is consistent with the square steel 18. By rotating the handle 2, the square steel 18, the valve stem 17, and the valve ball can be driven to rotate the valve, thereby realizing the opening and closing control of the valve body 11.

[0029] Specifically, a spring 26 is disposed at the bottom of the button 21. When the button 21 is pressed, the button 21 compresses the spring 26. When the button 21 is released, the spring 26 rebounds and lifts the button 21 to reset.

[0030] Specifically, a spring 27 is provided on the side of the lever 23 away from the slot 181. When the button 21 is pressed to force the lever 23 out of the slot 181, the lever 23 compresses the spring 27. When the button 21 is released to break away from the force against the lever 23, the spring 27 rebounds to force the lever 23 back to its original position.

[0031] To sum up, in the adjustable valve structure, the setting of the sealing ring 19 ensures the sealing of the valve stem 17, and the setting of the reinforcing rib 111 ensures the connection strength between the flange 13 and the flange 2 14 and the valve body 11. By pressing the button 21, the clamping rod 23 can be driven to disengage from the connection with the clamping groove 181, and the direction can be adjusted by pulling the handle 2 upward. After the adjustment, it can be reconnected with the square steel 18. The reversing process is simple and fast, which greatly reduces the difficulty of assembly. The structure is simple and compact, in line with economic benefits, and has broad application prospects.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
