Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically refers to a ball valve ball with a filtering function. Background Technology

[0002] The ball of a ball valve is the core component of the ball valve and is widely used in fluid pipelines in petrochemical, water treatment, energy and other fields. By rotating the ball, the flow hole inside the ball is aligned or offset from the valve body channel, so as to realize the conduction, cut-off and flow regulation of fluid.

[0003] Existing ball valve designs with built-in filters have significant shortcomings. Some solutions employ detachable connections to the inside of the ball for easy assembly and disassembly of the filter structure. However, these typically require complex guide rails, clips, or excessive connectors inside the ball or on the filter structure. This not only increases the number of parts and manufacturing costs but also makes installation and disassembly extremely difficult within the confined space of the ball, increasing the risk of leaks. Furthermore, the inconvenient assembly and disassembly operations within the narrow space make it difficult to meet the needs of rapid maintenance. Therefore, there is an urgent need for a ball valve body with a simple structure and convenient assembly and disassembly, incorporating filtering functionality. Utility Model Content

[0004] The present invention aims to provide a ball valve ball, which has a detachable filter assembly inside the flow hole of the ball body. The filter assembly is detachably connected to the filter frame by means of a support step and a fixed base, respectively, through a connecting plate and a connecting boss, so as to achieve stable installation and quick assembly and disassembly of the filter assembly, thereby solving the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a ball valve ball with a filtering function, comprising: The sphere body has a through-hole for flow; The mounting structure includes a support step located on the inner wall of one end of the flow hole of the sphere body, and a fixing base located on the inner wall of the other end of the flow hole. The filter assembly is detachably disposed as a whole within the flow hole. The filter assembly includes a filter frame and a filter element disposed within the filter frame. The inlet end of the filter frame is provided with a docking plate that is detachably connected to a support step via fasteners. The outlet end of the filter frame is provided with a connecting boss that is detachably connected to a fixed base.

[0006] The present invention is further configured such that one end of the fixed base is connected to the inner wall of the flow hole, and the other end is bent and extended toward the inlet end of the filter frame to form an opening for the insertion of the connecting boss.

[0007] The present invention is further configured such that the connecting boss and the opening of the fixed base are detachably connected by a threaded connection.

[0008] The present invention is further configured such that a positioning structure is provided between the docking plate and the supporting step, including: Positioning boss, fixed to the supporting step; A positioning groove is formed on the mating plate, and the positioning groove matches the positioning boss.

[0009] The present invention is further configured such that the positioning boss is provided with a plurality of locking grooves evenly distributed along the circumference, and the bottom of the locking groove is flush with the outer end of the mating plate, and the fastener is located in the locking groove.

[0010] The present invention is further configured such that the fastener comprises: The locking hole extends from the outer end face of the positioning boss to the support step. A locking bolt is connected to the locking hole, and the head of the locking bolt presses against the outer end of the mating plate after the connection is complete.

[0011] The present invention is further configured such that both the supporting step and the fixed base are annular structures integrally formed with the sphere body.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 : Example 1: This embodiment provides a ball valve ball with filtering function, including: The sphere body has a through-hole for flow; The mounting structure includes a support step located on the inner wall of one end of the flow hole of the sphere body, and a fixing base located on the inner wall of the other end of the flow hole. The filter assembly is detachably disposed as a whole within the flow hole. The filter assembly includes a filter frame and a filter element disposed within the filter frame. The inlet end of the filter frame is provided with a docking plate that is detachably connected to a support step via fasteners. The outlet end of the filter frame is provided with a connecting boss that is detachably connected to a fixed base.

[0018] The ball body is used to support the flow hole, mounting structure, and filter components, and to achieve fluid control. Its function is to control the flow by rotating the flow hole to align or offset it with the valve body channel. Its structure is a spherical structure with a through flow hole inside. The shape is a standard sphere to ensure a tight seal with the valve seat. It is located inside the ball valve body and can rotate with the valve stem. It is generally fitted to the valve seat. The arc-shaped outer wall of the ball body is in close contact with the sealing surface of the valve seat. The seal is achieved by the tightness of the fit when the ball rotates. It is generally fixed to the valve stem by a key connection.

[0019] The mounting structure achieves bidirectional fixation of the filter assembly through the cooperation of the support step and the fixed base, preventing displacement under fluid impact. The support step provides an installation reference for the docking plate, withstands the pressure at the filter frame inlet end, and is fixed to the docking plate with fasteners. Its construction consists of an annular step extending from the inner wall of one end of the flow hole towards the center, with its step surface perpendicular to the axis of the flow hole. It can be fixedly connected to the sphere body by welding or other methods. The fixed base is used to fix the filter frame outlet end and forms a bidirectional positioning with the support step. It restricts the displacement of the filter frame outlet end to prevent shaking or detachment. Its construction consists of a protruding structure extending from the inner wall of the other end of the flow hole towards the center, and is fixedly connected to the sphere body by welding or other methods. The connecting boss to the filter assembly is detachably connected.

[0020] The filter assembly is used to filter impurities in fluids, purifying them to prevent pipe blockage or equipment damage. It is also easily disassembled for maintenance. Its modular structure includes a filter frame, filter element, connecting plate, and connecting boss. The overall shape is a columnar structure adapted to the flow orifice, detachably mounted within it, with supporting steps and a fixed base at both ends. The detachable connection is achieved through the connecting plate and supporting steps, and the connecting boss and fixed base. The filter frame serves as the mounting carrier and supports the filter element, fixing its position to ensure uniform fluid filtration. It also provides a connection base for the connecting plate and connecting boss. Its structure is a frame with an internal space for the filter element, connected to the connecting plate and connecting boss at both ends. It is a columnar frame with an external shape adapted to the flow orifice, and the filter element is fixed inside. A handle, a plate-like structure, can also be provided at the filter frame inlet for user operation, welded to the inlet to improve the overall assembly and disassembly efficiency of the filter assembly.

[0021] The connecting plate is used to fix the inlet end of the filter frame to the support step, transfer the force of the inlet end to the support step and assist in installation and positioning. Its structure is a plate-shaped structure with a fluid passage in the center. It is an annular plate with a diameter adapted to the support step. It can be integrally formed or welded to the filter frame and can be detachably connected to the support step by fasteners.

[0022] Fasteners are used to secure the connection between the mating plate and the support step, and their function is to provide axial locking force to prevent the filter assembly from loosening or fluid leakage.

[0023] The connecting boss is used to connect the outlet end of the filter frame to the fixed base, cooperates with the fixed base to limit the displacement of the outlet end, and forms a two-way fixation with the docking plate.

[0024] One end of the fixed base is connected to the inner wall of the flow hole, and the other end is bent and extended toward the inlet end of the filter frame, forming an opening for the insertion of the connecting boss. The connecting boss and the opening of the fixed base are detachably connected by a threaded connection. The purpose of the above design is to achieve accurate positioning, stable fixation, and convenient assembly and disassembly of the filter assembly outlet end through the structural fit and threaded connection between the fixed base and the connecting boss, while enhancing the connection sealing performance. One end of the fixed base connects to the inner wall of the flow hole, forming an annular protrusion. The other end bends and extends towards the filter frame inlet to form an opening, with internal threads machined on the inner wall of the opening. The connecting boss is a columnar structure protruding outward from the filter frame outlet, matching the opening of the fixed base in shape and having external threads machined on its outer wall. During installation, the connecting boss is aligned with the opening of the fixed base and screwed in. The threads engage to achieve a tight connection, accurately positioning the filter assembly and preventing it from loosening under fluid impact through axial locking force. The bend in the opening structure also enhances radial constraint, preventing the connecting boss from wobbling. The threaded connection facilitates quick tightening or loosening, allowing for convenient assembly and disassembly of the filter assembly. Furthermore, the threaded mating surface reduces gaps, improving the sealing performance at the outlet. When the filter frame is rotated to screw the connecting boss into the fixed base, the entire filter assembly is pulled towards the outlet end under the guidance of the threads, resulting in a closer fit between the inlet end mating plate and the support step.

[0025] A positioning structure is provided between the docking plate and the supporting step, including a positioning boss fixed to the supporting step and a positioning groove on the docking plate that matches the positioning boss. The purpose of this design is to ensure quick alignment of the docking plate and the supporting step during installation by cooperating with the positioning boss and the positioning groove, avoiding installation deviations of the filter assembly, and simultaneously improving connection stability. The positioning boss is a raised structure fixed to the surface of the supporting step, generally in the shape of a regular block or ring. The positioning groove is a recessed structure on the surface of the docking plate, whose shape and size match the positioning boss. In terms of connection method, when installing the filter assembly, the positioning groove of the docking plate is aligned with the positioning boss of the supporting step and inserted. The initial positioning is achieved through the engagement of the positioning boss and the positioning groove, which allows the holes of the docking plate and the supporting step to be aligned without repeated adjustments, facilitating the subsequent installation of fasteners. At the same time, this engagement structure can restrict the relative rotation between the docking plate and the supporting step, preventing circumferential displacement of the filter assembly under fluid impact, further ensuring the overall stability of the filter assembly installation.

[0026] The positioning boss has multiple locking grooves evenly distributed circumferentially, and the bottom of each locking groove is flush with the outer end of the mating plate. The fastener is located within the locking groove. The fastener includes a locking hole extending from the outer end face of the positioning boss to the supporting step, and a locking bolt connected to the locking hole, the head of which presses against the outer end of the mating plate after full connection. The purpose of this design is to achieve a stable connection between the mating plate and the supporting step through the cooperation of the locking grooves of the positioning boss and the fastener, while optimizing the fastener installation space and preventing the fastener from protruding and affecting the structural compactness. The positioning boss has multiple locking grooves evenly distributed around its circumference. The bottom of the locking groove is flush with the outer end of the mating plate, and the groove is concave to accommodate fasteners. The fastener consists of locking holes and locking bolts. The locking holes extend from the outer end face of the positioning boss to the support step, and the locking bolts are matched with the locking holes. In terms of connection, during installation, the locking bolts are inserted into the locking holes and tightened. The head of the bolt will be located in the locking groove and press against the outer end of the mating plate. This not only secures the mating plate and the support step tightly through the pressure of the locking bolt, preventing gaps between them, but also allows the locking groove to accommodate the bolt head, preventing the head from protruding and occupying extra space or interfering with other components. At the same time, the evenly distributed locking grooves and fasteners around the circumference ensure that the mating plate is subjected to uniform force, reducing local stress concentration and further ensuring the stability of the connection.

[0027] In this embodiment, during assembly, the filter element is first inserted into the filter frame to form a filter assembly. Then, the filter assembly is placed into the flow hole of the ball body, allowing the positioning groove on the mating plate to engage with the positioning boss on the support step for initial positioning. Next, the connecting boss is aligned with the opening formed by the bending extension of the fixed base towards the filter frame inlet end and fixed via a threaded connection. Finally, a locking bolt is inserted through the outer end face of the positioning boss into the locking hole of the support step. After tightening, the head of the locking bolt is positioned within the evenly spaced locking grooves on the circumference of the positioning boss. Furthermore, the outer end of the connecting plate is pressed against the filter element to fix it within the flow hole. During operation, the ball body rotates with the valve stem. When the flow hole aligns with the valve body channel, fluid flows in from one end of the flow hole. After impurities are intercepted by the filter element, the clean fluid flows to the other end of the flow hole and is discharged. When maintenance is required, first unscrew the locking bolt to disconnect the connecting plate from the support step, then unscrew the threaded engagement between the connecting boss and the fixed base. The filter element can then be removed entirely from the flow hole. After cleaning or replacing the filter element, the assembly steps can be reversed for reinstallation and use. In summary, the assembly process of this utility model demonstrates the superiority of its modular design. Specifically, the three steps of "placing," "turning," and "tightening" are interconnected, simplifying the operation in narrow spaces and avoiding the cumbersome process of multiple tools, multiple angles, and repeated adjustments required in traditional solutions.

[0028] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
