Description

Technical Field

[0001] The utility model relates to a valve component, in particular to a stainless steel sphere. Background Art

[0002] The ball is a key component in a valve. It is typically spherical, with a central channel. Rotating, the ball controls the flow of the valve, thereby controlling the flow of the medium. Balls are typically made of materials such as stainless steel, copper, and cast iron, which offer excellent corrosion resistance and mechanical properties.

[0003] Since valves are used in a wide range of fields, single-function valves are no longer suitable for the complex working conditions currently on the market. Therefore, under the research and development of existing researchers in this field, spheres have been given various functions, including a sphere structure with a filtering function. The sphere with a filtering function includes a sphere body, a medium channel arranged in the sphere body, a filter installed in the medium channel, and a fixed component that fixes the filter in the medium channel. Since this fixed installation method is limited by the size of the medium channel, when the medium channel is small, the operating space during the installation process is greatly limited, thereby increasing the difficulty of installation, resulting in reduced product production efficiency and production quality. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel sphere, which can realize the convenient disassembly and assembly of the filter screen, thereby improving the production efficiency and production quality of the product.

[0005] The above technical objectives of the present utility model are achieved through the following technical solutions: a stainless steel sphere, including a sphere body, a medium channel arranged in the sphere body, an upper docking portion arranged above the sphere body, a lower docking portion arranged below the sphere body and a filter screen, and also including a mounting frame for installing the filter screen, an assembly component for fixing the two is formed between the mounting frame and the filter screen, the mounting frame is installed in the medium channel and does not interfere with the medium passing through the medium channel, and a locking member is provided on the outside of the sphere body to cooperate with the medium channel for fixing the mounting frame located in the medium channel.

[0006] By adopting the above technical solution, the mounting frame and filter are fixed together through the assembly component, and then the two are installed in the media channel. Then, the mounting frame is fixed in the media channel by the locking member provided on the outside of the sphere body. This arrangement makes the installation of the filter unrestricted by the media channel, thereby realizing convenient assembly and disassembly of the filter, thereby improving the production efficiency and quality of the product.

[0007] It is further configured as follows: the mounting frame includes at least one mounting ring and the filter screen is arranged on the end surface of the mounting ring, and the assembly component includes a positioning structure formed between the mounting ring and the filter screen and a limiting structure for limiting the positioning structure to be in a positioning state.

[0008] By adopting the above technical solution, the positioning structure is used to locate the assembly position of the filter screen and the mounting ring to ensure the processing quality of the product, and then cooperates with the set limiting structure to fix the two to achieve the final assembly and fixation purpose.

[0009] It is further configured that: there are two mounting rings, the two mounting rings are coaxially arranged and the filter screen is arranged between the two mounting rings, and when the assembly component is in the assembled state, the opposite ends of the two mounting rings are flush with the medium channel opening.

[0010] By adopting the above technical solution, the resistance encountered by the medium when flowing through the mounting ring is reduced through this setting structure, so that the transmission of the medium is smoother, thereby reducing the occurrence of resonance and scouring.

[0011] It is further configured that: the outer diameter of the mounting ring is adapted to the diameter of the medium channel, and the limiting structure has a limiting state in which the limiting positioning structure is in a positioning state and a non-limiting state.

[0012] By adopting the above technical solution, the disassembly and assembly operations of the assembly components are made more convenient through this setting structure.

[0013] It is further configured that: the positioning structure is a positioning groove provided on one end surface of the two mounting rings facing the filter screen.

[0014] By adopting the above technical solution, the positioning groove is provided to realize the assembly positioning of the filter screen and the mounting ring.

[0015] It is further configured as follows: the limiting structure is a plurality of limiting parts, each of which has two limiting ends and is distributed around the center of the medium channel. The two limiting ends of the limiting parts are respectively inserted into two mounting rings to limit the two mounting rings from moving axially opposite to each other along the medium channel.

[0016] By adopting the above technical solution, after the filter screen and the mounting ring are assembled, the two limiting ends of the limiting member are respectively inserted into the two mounting rings to limit the separation of the mounting ring and the filter screen.

[0017] It is further configured that: when the limiting member is in the limiting state, the two mounting rings are provided with embedding grooves corresponding to the limiting member so that the limiting member does not protrude from the outer peripheral wall of the mounting ring.

[0018] By adopting the above technical solution, space is reserved for the installation of the limiting member by setting the embedding groove, thereby ensuring the adaptation and fit between the outer peripheral wall of the installation ring and the medium channel.

[0019] It is further configured that the locking member is a bolt that is thread-sealed with the spherical body and abuts against the mounting ring.

[0020] By adopting the above technical solution, the bolt structure presses against the mounting ring to restrict the movement of the mounting ring along the axis of the medium channel.

[0021] It is further configured that: when the filter screen is installed in the positioning groove, a compression gap is formed between the two end surfaces of the two mounting rings facing each other.

[0022] By adopting the above technical solution, a tight fit between the filter screen and the mounting ring is achieved through the formed compression gap.

[0023] In summary, the present invention has the following beneficial effects: the present invention can realize the convenient disassembly and assembly of the filter screen, thereby improving the production efficiency and production quality of the product. BRIEF DESCRIPTION OF THE DRAWINGS
