Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve processing, in particular to a low-torque opening and closing ball valve. Background Art
[0002] A ball valve's opening and closing member (the ball) is driven by the valve stem and rotates around the stem's axis. The ball valve controls the flow of fluid by rotating the ball. When the ball rotates to contact the valve seat, it forms a seal, preventing fluid leakage. When the ball rotates away from the valve seat, fluid can flow through the passageway within the valve body.
[0003] Ordinary ball valves require a large torque when opening and closing, which increases the difficulty of operation and labor intensity. After long-term use, the large opening and closing torque of ordinary ball valves will cause increased wear of valve stems, bearings and other components, thereby affecting the service life. In addition, in the face of special circumstances, ordinary ball valves require strong force to unscrew due to excessive torque, which will delay rescue time and cause serious consequences. Therefore, a low-torque opening and closing ball valve is needed.
[0004] The reason for this problem is that in situations where ball valves need to be operated frequently, ordinary ball valves require large torque, which increases the physical burden of operators and reduces work efficiency. High torque will increase the friction of ball valve components, causing additional wear and damage to valve stems, bearings and other components. In the face of fire or other critical situations, if the operator has little strength, he will not be able to open the ball valve, which will lead to serious consequences. Therefore, we propose a new type to solve the above problem. Utility Model Content

In addition, when facing special circumstances, ordinary ball valves require strong force to unscrew due to excessive torque, which will delay rescue time and cause serious consequences.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a low-torque opening and closing ball valve, comprising a valve body, a spherical valve core is provided inside the valve body, a labor-saving driving member is provided on the top of the valve body, and the labor-saving driving member includes a first gear, a second gear, a hexagonal column and a rotating rod;

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0024] The embodiment of the present application solves the problem that ordinary ball valves require a large torque when opening and closing, which increases the difficulty of operation and labor intensity. After long-term use, ordinary ball valves will suffer from increased wear of valve stems, bearings and other components due to the large opening and closing torque, thereby affecting the service life. In addition, when facing special circumstances, ordinary ball valves require strong force to unscrew due to excessive torque, which will delay rescue time and cause serious consequences.
[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0026] The embodiment of the utility model discloses a low-torque opening and closing ball valve.
[0027] According to the attached Figure 1-4 As shown, it includes a valve body 1, a spherical valve core 11 is provided inside the valve body 1, and a labor-saving driving member 2 is provided on the top of the valve body 1. The labor-saving driving member 2 includes a first gear 21, a second gear 22, a hexagonal column 23 and a rotating rod 24;
[0028] When the device is in use, the handle at the top of the adjustable handle 25 is grasped and lifted upward, so that the rotating rod 24 is taken out of the storage block 3, and rotated clockwise to drive the second gear 22 to rotate. The second gear 22 is engaged with the first gear 21, driving the spherical valve core 11 to rotate. If it feels more laborious, grasp the insertion strip 253 on one side of the rotating rod 24 and pull it outward. The spring 254 is tightened, so that the block 255 is withdrawn from the fixed groove 252. The other hand grasps the handle 251 and pulls it outward. At this time, the insertion strip 253 is released. Under the reaction force of the spring 254, the block 255 presses against the outside of the handle 251 The handle 251 continues to be pulled outward, and the block 255 slides to the top of the fixing groove 252, and is locked into it under the reaction force of the spring 254, thereby completing the fixation of the handle 251. Due to the principle of leverage, the longer the handle 251, the less effort it takes. After the adjustment is completed, pull the insert 253 and push the handle 251 inward. Push it to the bottom and release the insert 253. Under the reaction of the spring 254, the block 255 is locked into the inside of the fixing groove 252, and the rotating rod 24 is rotated to reach the top of the storage block 3, and the rotating rod 24 is pushed downward to complete the storage of the rotating rod 24.
[0029] The first gear 21 and the second gear 22 are both rotatably disposed on the top of the valve body 1. The first gear 21 meshes with the second gear 22. The first gear 21 is fixedly connected to the spherical valve core 11. The hexagonal column 23 is movably inserted into the interior of the second gear 22. The rotating rod 24 is fixedly connected to the top of the hexagonal column 23.
[0030] An adjustable handle 25 is provided inside the rotating rod 24, and the hexagonal column 23 is movably inserted into the inside of the second gear 22, which can drive the second gear 22 to rotate but will not drive the second gear 22 to slide vertically, ensuring that the first gear 21 and the second gear 22 can be effectively engaged. An anti-slip block is fixed to the bottom of the hexagonal column 23 to prevent the hexagonal column 23 from sliding out of the inside of the slot 27.
[0031] The adjustable handle 25 includes a handle 251 , a fixing slot 252 and a protrusion 256 ;
[0032] The fixing groove 252 is symmetrically formed on one side of the handle 251 along the central axis. The protrusion 256 is fixedly connected to the end of the handle 251. The protrusion 256 prevents the handle 251 from sliding out of the interior of the rotating rod 24. The inner wall of the rotating rod 24 can clamp the protrusion 256, so that the handle 251 does not slide out and affect subsequent normal use. The adjustable handle 25 also includes an insert 253 and a spring 254.
[0033] The inserting strip 253 is movably inserted into one side of the rotating rod 24, and the spring 254 is wound on the outer surface of the inserting strip 253. One end of the spring 254 is fixedly connected to the inserting strip 253, and the other end of the spring 254 is fixedly connected to the rotating rod 24. The adjustable handle 25 also includes a clamping block 255; the clamping block 255 is fixedly connected to the end of the inserting strip 253, and the clamping block 255 is movably clamped into the inside of the fixing groove 252.
[0034] A fixing box 26 is fixedly installed on the top of the valve body 1, and a slot 27 is opened inside the fixing box 26. The hexagonal column 23 is movably inserted into the slot 27. The top of the fixing box 26 is fixedly connected to the storage block 3, and the rotating rod 24 is movably connected to the inside of the storage block 3.
