Description

A valve core with filtering function Technical Field

[0001] This utility model relates to the field of valve core technology, and in particular to a valve core with a filtering function. Background Technology

[0002] Ball valves, widely used in numerous fields, play a crucial role in fluid transport and control due to their simple structure, rapid opening and closing, and excellent sealing performance. However, in actual operating conditions, fluid media often contain various impurities such as mud, rust, and debris. Once these impurities enter the ball valve, they can cause wear to critical components like the ball and seat, damaging the sealing structure and potentially clogging the pipeline, thus affecting the normal operation of the entire fluid transport system.

[0003] Currently, to prevent impurities from entering ball valves, a common practice is to install a separate filter in the pipeline system. However, a separate filter increases the complexity of the pipeline system and the installation space requirements. Another approach is to install the filter inside the valve, such as a novel filter ball valve disclosed in patent document CN222142043U. This valve includes a valve body and an inlet and an outlet located at both ends of the valve body. The valve body contains a ball valve for blocking liquid flow, and the upper end of the ball valve has a valve stem for controlling the opening and closing of the ball valve. A valve seat is provided between the valve body and the ball valve to facilitate fixing the ball valve. A filter device for filtering liquid impurities is located at the inlet of the valve seat. Although this design integrates filtration and control functions and simplifies the pipeline system, when the filter needs to be replaced or cleaned, it is necessary to reach in from the inlet to remove the filter. However, this requires another valve to block the fluid transport path before the valve body and connecting pipeline can be disconnected, which is inconvenient. Summary of the Invention

[0004] This invention provides a valve core with a filtering function to solve the problem of inconvenient disassembly of filter components in the prior art.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A valve core with a filtering function includes a spherical valve core installed inside a valve body. The spherical valve core has a filter element inside, which is used to filter impurities in the fluid within the internal fluid channel of the spherical valve core. The valve body has an extension perpendicular to the axial direction of the valve body flow channel. The extension has an installation channel inside that communicates with the internal fluid channel of the spherical valve core. The bottom of the extension is detachably connected to an installation component. When the installation component is installed on the extension, the filter element is installed inside the internal fluid channel of the spherical valve core.

[0007] Preferably, the lower end of the filter element is provided with a mounting rod, the mounting element is threadedly connected to the extension, and a mounting seat is rotatably connected to the inner bottom wall of the mounting element.

[0008] Preferably, when the spherical valve core blocks the flow channel inside the valve body, it can drive the filter element to align with the installation channel, thereby enabling the removal of the filter element.

[0009] Preferably, the filter element includes a mounting frame and a filter screen, and the filter screen is detachably connected inside the mounting frame.

[0010] Preferably, the filter screen is provided with a collection box with a hollowed-out side.

[0011] Preferably, the sidewall of the filter element is provided with an elastic sealing gasket.

[0012] The beneficial effects of this utility model are: by rotating the spherical valve core to block the fluid transport, the spherical valve core drives the filter element to align with the installation channel, thereby facilitating the disassembly and installation of the filter element. The filter element can be disassembled and installed without the need to set up a blocking valve on the transport pipeline, which is more convenient and faster. Attached Figure Description

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Referring to Figures 1-6, a valve core with a filtering function includes a spherical valve core 2 installed inside a valve body 1. When the fluid channel inside the spherical valve core 2 is aligned with the fluid channel inside the valve body 1, fluid transport can be achieved. Conversely, when the spherical valve core 2 is rotated to completely misalign the two, fluid transport is blocked through the spherical valve core 2. Inside the spherical valve core 2, a filter element 3 is provided for filtering impurities from the fluid within the fluid channel. An extension 4 perpendicular to the axial direction of the flow channel in the valve body 1 is also provided on the valve body 1. The extension 4 has an internal mounting channel 41 that communicates with the internal fluid channel of the ball valve core 2. The filter element 3 is slidably connected to the mounting channel 41, and the bottom of the extension 4 is detachably connected to the mounting element 5. When the filter element 3 is installed in the ball valve core 2 through the mounting channel 41, the mounting element 5 is then installed on the extension 4. At this time, the limiting effect of the mounting element 5 on the filter element 3 allows the mounting element 5 to be installed in the internal fluid channel of the ball valve core 2, thereby achieving impurity filtration of the liquid flowing through the fluid channel of the valve body 1.

[0023] Referring to Figure 2, further, when the ball valve core 2 blocks the flow channel inside the valve body 1, it can drive the filter element 3 to align with the installation channel 41. The filter element 3 is located at the upper end of the installation channel 41. At this time, after removing the mounting part 5 from the extension 4, the mounting part 5 is released from contact with the filter element 3, and the filter element 3 can be disassembled. Since the ball valve core 2 has blocked the valve body 1, the fluid is stopped from being transported. The disassembly and assembly of the filter element 3 is not affected by the fluid flow. There is no need to set other valve opening and closing components on the conveying pipeline to block the fluid transport. The disassembly and assembly of the filter element 3 can be carried out, which is more convenient and faster.

[0024] Referring to Figures 2 and 6, the lower end of the filter element 3 is further provided with a mounting rod 31. The mounting part 5 is threadedly connected to the extension part 4, and a mounting seat 51 is rotatably connected to the inner bottom wall of the mounting part 5. When the mounting part 5 is rotated, the mounting seat 51 abuts against the mounting rod 31, thereby generating an opposing force on the mounting rod 31. This causes the mounting rod 31 to drive the filter element 3 to be installed into the spherical valve core 2. When the spherical valve core 2 is rotated and the filter element 3 is moved synchronously, the mounting rod 31 can drive the mounting seat 51 to rotate synchronously through the rotational connection between the mounting seat 51 and the mounting part 5, reducing the frictional force on the bottom of the mounting rod 31.

[0025] The filter element 3 includes a mounting frame 32 and a filter screen 33. The filter screen 33 is detachably connected inside the mounting frame 32. After the filter element 3 is removed, it is easy to clean the impurities clogging the mesh holes of the filter screen 33. At the same time, it is easy to disassemble when the filter screen 33 needs to be replaced. The filter screen 33 can be connected to the mounting frame 32 by means of snap-fit ​​or threaded connection.

[0026] Referring to Figures 1-5, the filter screen 33 is further provided with a collection box 34 with a hollowed-out side. On the one hand, the hollowed-out collection box 34 does not affect the passage of liquid through the fluid channel. On the other hand, some impurities intercepted by the filter screen 33 can fall into the collection box 34 for collection, reducing the number of impurities that have been intercepted and filtered falling back into the liquid. When the filter element 3 is removed, the impurities in the collection box 34 can be cleaned.

[0027] Referring to Figure 6, the side wall of the filter element 3 is further provided with an elastic sealing gasket 35. The elastic sealing gasket 35 can be made of elastic materials such as rubber. When the filter element 3 is installed inside the ball valve core 2, the elastic sealing gasket 35 abuts and squeezes against the inner wall of the installation channel 41 inside the ball valve core 2, making the connection between the two tighter and thus reducing the possibility of impurities passing through.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
