Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a novel ball valve core. Background Art

[0002] In existing ball valve designs, the ball core usually adopts a spherical structure. Although this design can meet basic fluid control needs, there are some problems in actual application. First, the sealing performance of the spherical ball core is often poor. This is mainly because the contact sealing surface between the ball and the valve seat is large, which can easily lead to loose sealing, thus affecting the sealing effect of the valve. Secondly, the spherical ball core is prone to wear during use, especially when the fluid contains particulate matter, the wear problem is more serious, which will shorten the service life of the valve. In addition, the production cost of the spherical ball core is high, mainly because its structure is complex, the processing is difficult, and more materials and processing steps are required.

[0003] Furthermore, the larger contact area between the spherical ball and the valve seat results in increased operating torque. During the valve opening and closing process, greater torque is required to overcome this greater contact resistance, which not only increases operational difficulty but also places a greater strain on the valve actuator, impacting the valve's service life and reliability.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a new ball valve core. Utility Model Content

[0005] The purpose of this utility model is to provide a novel ball valve core to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A new technical solution for a ball valve core includes a rotating column, an upper connecting block is installed at the lower part of the rotating column, an arc-shaped valve plate is provided at the edge of the upper connecting block, an arc-shaped concave surface is provided on the inner side of the arc-shaped valve plate, an arc-shaped convex surface is provided on the outer side of the arc-shaped valve plate, and a lower connecting block is installed at the bottom of the arc-shaped valve plate.

[0008] As a preferred technical solution, a sealing recess is provided on the rotating column, and the sealing recess is used to install a sealing strip. A rotating recess is provided below the sealing recess, and the rotating recess is used for the rotation of the valve core. A rotating block is installed at the bottom of the lower connecting block, and the rotating block is used for the rotation of the valve core.

[0009] As a preferred technical solution, the rotating column, sealing recess, rotating recess, rotating block, arc-shaped valve plate, arc-shaped concave surface, upper connecting block and lower connecting block are processed in one piece.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] This utility model provides a new ball valve core. Its curved valve disc design reduces the contact area with the valve seat, thereby improving sealing performance, reducing the possibility of leakage, and ensuring the accuracy and reliability of fluid control. Due to the reduced contact area, wear is significantly improved. Especially when the fluid contains particulate matter, the new ball valve core experiences much less wear than traditional spherical cores, thereby extending the service life of the valve. The use of one-piece processing simplifies the manufacturing process, reduces material usage and processing steps, and effectively reduces production costs. Furthermore, the contact area with the valve seat is reduced, thereby reducing operating torque, making the valve easier to open and close, alleviating the burden on the drive device, and improving the service life and reliability of the valve.

[0016] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0017] like Figure 1 、 Figure 2 and Figure 3As shown, the present invention provides a novel ball valve core technical solution: comprising a rotating column 1, an upper connecting block 22 mounted at the bottom of the rotating column 1, an arc-shaped valve disc 2 provided at the edge of the upper connecting block 22, an arc-shaped concave surface 21 provided on the inner side of the arc-shaped valve disc 2, an arc-shaped convex surface provided on the outer side of the arc-shaped valve disc 2, and a lower connecting block 23 mounted at the bottom of the arc-shaped valve disc 2. A sealing recess 11 is provided on the rotating column 1 for mounting a sealing strip, a rotating recess 12 is provided below the sealing recess 11 for rotating the valve core, and a rotating block 13 is mounted at the bottom of the lower connecting block 23 for rotating the valve core. The rotating column 1, sealing recess 11, rotating recess 12, rotating block 13, arc-shaped valve disc 2, arc-shaped concave surface 21, upper connecting block 22, and lower connecting block 23 are manufactured as a single piece.

[0018] In an embodiment, the one-piece processing adopts wear-resistant high-strength plastic injection molding. The material of the rotating column 1 is preferably a high-strength metal material, such as stainless steel or alloy steel, to ensure that it has sufficient strength and corrosion resistance. The upper connecting block 22 and the lower connecting block 23 can be made of the same material as the rotating column 1, or other suitable engineering plastics or composite materials to reduce the overall weight and reduce costs. The material of the arc-shaped valve plate 2 is preferably a rubber or synthetic rubber material with high wear resistance and good elasticity to improve the service life and sealing performance of the valve plate.

[0019] The sealing strip installed in the sealing recess 11 can be made of a rubber material that is resistant to high temperature, high pressure and corrosion to adapt to the use requirements under different working conditions. In addition, the rotating block 13 can cooperate with the driving mechanism in the valve body to realize the automatic control of the valve.

[0020] The present invention reduces the contact area with the valve seat through the design of the arc-shaped valve disc, thereby improving the sealing performance, reducing the possibility of leakage, and ensuring the accuracy and reliability of fluid control. Secondly, due to the reduction in contact area, the wear problem is significantly improved. Especially when there are particulates in the fluid, the wear degree of the new ball valve core is much less than that of the traditional spherical ball core, thereby extending the service life of the valve. Thirdly, the use of one-piece processing simplifies the manufacturing process, reduces material usage and processing steps, and effectively reduces production costs. Finally, the contact area with the valve seat is reduced, thereby reducing the operating torque, making the valve easier to open and close, reducing the burden on the drive device, and improving the service life and reliability of the valve.
