Description

Technical Field

[0001] The utility model relates to the technical field of electric ball valves, in particular to a new type of anti-clogging electric ball valve. Background Art

[0002] Electric ball valve is an important actuator in industrial automation control system. It is a valve that rotates around the axis of the valve stem according to the movement of the valve disc. The change of the valve seat opening is directly proportional to the valve disc stroke. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. It is a pipeline pressure element for industrial automation process control.

[0003] After long-term use, the existing electric ball valves are easily clogged due to impurities in the water, thereby affecting the normal circulation of the ball valves and having low practicality. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a new type of anti-clogging electric ball valve.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of anti-clogging electric ball valve, including a ball valve body, a valve body is provided inside the ball valve body, a valve shaft is provided on the surface of the valve body, an electric control structure is provided on the end of the valve shaft, a support rod is provided inside the ball valve body, a connecting column is provided on the surface of the support rod, a second bearing is provided on the surface of the connecting column, a rotating sleeve is provided on the surface of the second bearing, and a cutting blade is provided on the surface of the rotating sleeve.

[0006] Preferably, connecting pipes are provided on both sides of the ball valve body, and flanges are provided on the surfaces of the connecting pipes.

[0007] Preferably, a first bearing is provided on the surface of the valve shaft, and the valve shaft is connected to the ball valve body through the first bearing.

[0008] Preferably, the shape and position of the valve body are matched with the ball valve body, and the shape of the valve body is matched with the cutting blade.

[0009] Preferably, the cutting blades are curved and arranged in a circular array on the surface of the rotating sleeve.

[0010] Preferably, the connecting column is axially symmetrically arranged on the surface of the connecting column, and the connecting column is rotatably connected to the rotating sleeve via a second bearing.

[0011] Preferably, the cutting blades are provided in two groups, and the bending directions of the two groups of cutting blades are opposite.

[0012] Beneficial Effects

[0013] In the utility model, a connecting column, a second bearing, a rotating sleeve and a cutting blade are adopted. Since the cutting blade is an airfoil similar to an airplane wing, when water flows through the ball valve body, a high-pressure area will be formed under the cutting blade, and a low-pressure area will be formed on the other side. This high and low pressure will generate lift, and the water will also hit the surface of the cutting blade when leaving the cutting blade, so that the cutting blade starts to rotate on the connecting column through the rotating sleeve and the second bearing. At the same time, since the cutting blade is in the form of a sharp blade, it is convenient to chop impurities during the rotation process to prevent the impurities from clogging the ball valve body, and the utility model is relatively high.

[0020] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

The second bearing 12 facilitates the rotation of the rotating sleeve 7 on the connecting column 10. The connecting column 10 is axially symmetrically arranged on the surface of the connecting column 10. The connecting column 10 and the rotating sleeve 7 are rotatably connected through the second bearing 12. The surface of the second bearing 12 is provided with a rotating sleeve 7. The surface of the rotating sleeve 7 is provided with cutting blades 11. The cutting blades 11 are curved, and the cutting blades 11 are arranged in a circular array on the surface of the rotating sleeve 7. There are two groups of cutting blades 11, and the bending directions of the two groups of cutting blades 11 are opposite. By setting two groups of cutting blades 11 with opposite bending directions, it is convenient to thoroughly chop impurities in the water flow and improve the fluidity.

[0024] The valve shaft 8 is controlled to rotate on the first bearing 9 through the electric control structure 4, thereby driving the valve body 5 to rotate, so as to control the circulation of water. Since the cutting blade 11 is an airfoil similar to an airplane wing, when the water flows through the ball valve body 1, a high-pressure area will be formed under the cutting blade 11, and a low-pressure area will be formed on the other side. This high and low pressure will generate lift, and the water will also hit the surface of the cutting blade 11 when leaving the cutting blade 11, so that the cutting blade 11 starts to rotate on the connecting column 10 through the rotating sleeve 7 and the second bearing 12. At the same time, since the cutting blade 11 is in the form of a sharp blade, it is convenient to chop impurities during rotation to prevent impurities from clogging the ball valve body 1. Specific embodiment 2:

[0027] In summary:

[0028] 1. The connecting column 10, the second bearing 12, the rotating sleeve 7 and the cutting blade 11 are adopted. Since the cutting blade 11 is an airfoil similar to an airplane wing, when water flows through the ball valve body 1, a high-pressure area is formed under the cutting blade 11, and a low-pressure area is formed on the other side. This high and low pressure generates lift, and the water flow will also hit the surface of the cutting blade 11 when leaving the cutting blade 11, so that the cutting blade 11 starts to rotate on the connecting column 10 through the rotating sleeve 7 and the second bearing 12. At the same time, since the cutting blade 11 is in the form of a sharp blade, it is convenient to chop impurities during the rotation process to prevent the impurities from clogging the ball valve body 1.
