Description

Technical Field

[0001] The utility model belongs to the technical field of valves, relates to a ball valve, and particularly relates to a double-adjustment ball valve. Background Art

[0002] A ball valve controls the on-off and flow rate of a fluid by the rotation of a ball in a valve body. When the ball rotates to coincide with the valve body passage, the valve is in an open state and the fluid can pass through smoothly; when the ball rotates to be perpendicular to the valve body passage, the valve closes and the fluid is cut off. It has the advantages of small fluid resistance, rapid opening and closing, good sealing performance, long service life, wide application range, etc.

[0003] In order to control the ball valve more simply, a double-adjustment ball valve is invented. A double-adjustment ball valve refers to a ball valve with a dual adjustment function. In addition to the traditional control rod, an automatically controlled second control structure is also provided to achieve remote and labor-saving control. However, the traditional double-adjustment valve sets a controller to control the valve, but the controller has a high cost and is difficult to maintain. Summary of the Invention

[0004] The purpose of the utility model is to provide a double-adjustment ball valve controlled by a motor to open and close in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A double-adjustment ball valve, characterized in that it includes a ball valve body with a closing structure inside, a driving rod is arranged on the top of the closing structure, a manual control rod is arranged on the driving rod, several vertical upward support rods are arranged on the ball valve body, a fixing ring is arranged on the top of the support rods, a driving motor is arranged on the fixing ring, a driving ratchet is arranged at the bottom of the driving motor, a passive ratchet symmetric to the driving ratchet is arranged on the driving rod, and a support spring is arranged between the driving motor and the driving ratchet.

[0006] In the above-mentioned double-adjustment ball valve, several clamping inclined teeth are arranged on the driving ratchet, and a clamping cavity is arranged between the clamping inclined teeth. A clamping boss is arranged at the bottom of the clamping cavity, and guiding rounded corners are arranged at the clamping boss and the ends of the clamping inclined teeth.

[0007] In the above-mentioned double-adjustment ball valve, a rotating shaft guiding part is arranged on the ball valve body, several limiting convex blocks are arranged on the rotating shaft guiding part, a guiding shell is arranged on the manual control rod, and a limiting cavity is arranged on the guiding shell.

[0008] In the above-mentioned double-adjustment ball valve, an output shaft is arranged on the driving motor, and a guiding key is arranged on the output shaft.

[0009] In the above-mentioned double-adjusting ball valve, a locking nut is provided on the top of the passive ratchet wheel.

[0010] Compared with the prior art, in this double-adjusting ball valve, by arranging a motor and a driving ratchet wheel driven by the motor on the valve body, the ball valve can achieve automatic and labor-saving control. The limiting bump and the limiting cavity are mutually abutted and limited to prevent the ball valve from being damaged due to the motor driving rotation too low. The guiding fillet enables the motor to release force when over-twisted to prevent the motor from being burned out due to overload. By limiting the length of the guiding key, the self-sliding force release of the driving ratchet wheel is controlled, further reducing the impact wear of components. Description of the Drawings

Detailed Embodiment

[0015] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0016] As Figure 1 、 2 、shown in 3, this double-adjusting ball valve includes a ball valve body 9 with a closing structure 8 inside. A driving rod 5 is provided on the top of the closing structure 8, and a manual control rod 10 is provided on the driving rod 5. A plurality of vertically upward support rods 3 are provided on the ball valve body 9. A fixing ring 2 is provided on the top of the support rod 3, and a driving motor 1 is provided on the fixing ring 2. A driving ratchet wheel 14 is provided at the bottom of the driving motor 1. A passive ratchet wheel 15 symmetrical to the driving ratchet wheel 14 is provided on the driving rod 5. A support spring 11 is provided between the driving motor 1 and the driving ratchet wheel 14. Driving the manual control rod 10 rotates the closing structure 8 to close or open it, and the motor drives to control the closing or opening of the closing structure 8 through the engagement and transmission of the driving ratchet wheel 14 and the passive ratchet wheel 15.

[0017] Preferably, a number of clamping helical teeth 18 are provided on the driving ratchet 14, and a clamping cavity 17 is provided between the clamping helical teeth 18. A clamping boss 20 is provided at the bottom of the clamping cavity 17, and guiding fillets 21 are provided at the clamping boss 20 and the ends of the clamping helical teeth 18. During manual control, the driving ratchet 14 is lifted by guiding through the clamping helical teeth 18. When driven by the motor, after the closing structure 8 moves in place, the motor continues to work. When the force is greater than the frictional force, the driving ratchet 14 is lifted too high, reducing motor damage.

[0018] Preferably, a rotating shaft guiding portion 16 is provided on the ball valve body 9, and a number of limiting bumps 6 are provided on the rotating shaft guiding portion 16. A guiding housing 7 is provided on the manual control rod 10, and a limiting cavity 4 is provided on the guiding housing 7. The fragrance bumps move in the limiting cavity 4 to prevent leakage due to excessive rotation of the closing structure 8 through resistance and limitation.

[0019] Preferably, an output shaft 13 is provided on the driving motor 1, and a guiding key 12 is provided on the output shaft 13. The driving ratchet 14 slides up and down on the guiding key 12, enabling the driving ratchet 14 to passively slide up and down and continuously providing partial power during force unloading.

[0020] Preferably, a locking nut 19 is provided on the top of the driven ratchet 15.

[0021] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0022] Although terms such as driving motor 1, fixed ring 2, support rod 3, limiting cavity 4, driving rod 5, limiting bump 6, guiding housing 7, closing structure 8, ball valve body 9, manual control rod 10, support spring 11, guiding key 12, output shaft 13, driving ratchet 14, driven ratchet 15, rotating shaft guiding portion 16, clamping cavity 17, clamping helical teeth 18, locking nut 19, clamping boss 20, guiding fillet 21, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
