Description
Technical Field
[0001] This utility model belongs to the field of valve technology, and in particular relates to a valve that facilitates the replacement of the filter device. Background Technology
[0002] During actual use, fluids often contain various impurities, particles, or suspended solids. These impurities gradually accumulate inside the valve, reducing its flow capacity and even affecting its normal function. Therefore, regularly replacing or cleaning the filter is crucial to ensuring the long-term stable operation of the valve.
[0003] Currently, most valves with filtration functions are designed with integrated filters, requiring complete disassembly for replacement. This increases replacement costs and maintenance difficulty. For some valves with filters, the connection method of the filter is relatively complex. When the filter needs to be replaced or cleaned, operators need to use specialized tools and spend a lot of time and effort to disassemble multiple bolts or connectors, which is cumbersome and inefficient. In addition, frequent disassembly of bolts, flanges and other components can easily lead to damage to seals and deformation of connectors, reducing the sealing and reliability of the connection, increasing the risk of leakage, and also shortening the service life of the valve and filter.
[0004] To address this issue, we provide a valve that facilitates the replacement of the filter device. Utility Model Content
[0005] The purpose of this invention is to provide a valve that facilitates the replacement of the filter device. Through the action of the filter cartridge, this device incorporates a flexibly detachable filter cartridge. The filter cartridge is connected to the installer via a snap-fit structure with the mounting shell. Replacement is achieved simply by unscrewing the threaded cover and pressing the first handle to unlock the snap-fit. Tool-free disassembly is required, significantly reducing maintenance difficulty and shortening operation time. Furthermore, it eliminates the need for complete valve disassembly or replacement of integrated components; only the filter cartridge needs to be replaced, reducing material waste and accessory costs. This is particularly suitable for scenarios requiring frequent cleaning or replacement of the filter device. It solves the problem of existing valves with filter devices having complex connection methods, requiring operators to use specialized tools and spend considerable time and effort disassembling multiple bolts or connectors when the filter device needs replacement or cleaning, resulting in cumbersome and inefficient operation.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a valve that facilitates the replacement of the filter device, including a valve body, an inlet fixed on one side of the valve body, and an outlet fixed on the side of the valve body away from the inlet.

[0042] For a specific implementation example, please refer to Implementation Example 1. Figure 1-8 This utility model is a valve for easy replacement of a filter device, including a valve body 1, an inlet 2 fixed on one side of the valve body 1, and an outlet 3 fixed on the side of the valve body 1 away from the inlet 2; a threaded groove 4 fixed on the end of the valve body 1 near the outlet 3, and a threaded cover 5 threadedly connected to the outside of the threaded groove 4; a connecting rod 6 fixed on the inner wall of the threaded cover 5, and an installer 7 fixed on one end of the connecting rod 6; an installation shell 8 snapped onto the outside of the installer 7, and a filter cylinder 9 fixed on one side of the installation shell 8; installation holes 10 fixed on both sides of the installation shell 8; a positioning plate 11 fixed inside the installer 7, and a first spring 12 fixed on both sides of the positioning plate 11, and a connecting plate 13 fixed on one end of the first spring 12; a locking rod 14 fixed on one side of the connecting plate 13, and through holes 15 fixed on both sides of the installer 7; the locking rod 14 passes through the through hole 15, and one end of the locking rod 14 is inserted into the installation hole 10.
[0043] Specifically, the installer 7 has a through groove 16 on the side away from the mounting shell 8, and a first handle 17 is fixed on one side of the connecting plate 13; the first handle 17 passes through the through groove 16 and is slidably connected to the through groove 16.
[0044] Furthermore, a filter screen 18 is fixed in the center of the filter cylinder 9, and the outer wall of the filter cylinder 9 is attached to the inner wall of the valve body 1; the filter screen 18 is located at one end of the outlet 3.
[0045] The operation process of this embodiment is as follows: When using this device, first operate the baffle 27 to cut off the flow. After the baffle 27 cuts off the flow, rotate the threaded cover 5 to separate it from the threaded groove 4. The threaded cover 5 drives the installer 7 to be removed as a whole through the connecting rod 6. Unlock the mounting shell 8, press the first handle 17 to make the locking rod 14 exit the mounting hole 10, separate the mounting shell 8 and the installer 7, and then remove the mounting shell 8 and the filter cartridge 9. After removing the old filter cartridge 9, align the mounting hole 10 on the surface of the mounting shell 8 of the new filter cartridge 9 with one end of the locking rod 14. Under the action of the first spring 12, it is locked and fixed with the installer 7. Then rotate the threaded cover 5 to reset it to the threaded groove 4 and fix the filter device. Replace the new filter cartridge 9. Afterwards, release the second handle 25, the second spring 26 returns to its original position, and drives the adjusting rod 24 and the baffle 27 to move towards the protective plate 20. The baffle 27 disengages from the inner wall of the valve body 1, releasing the blockage to the inlet 2 and allowing the fluid to flow in normally. This device is equipped with a detachable filter cartridge 9. The filter cartridge 9 is connected to the installer 7 through the snap-fit structure of the mounting shell 8. When replacing it, simply turn out the threaded cover 5 and press the first handle 17 to unlock the snap-fit. It can be quickly disassembled without tools, which significantly reduces the difficulty of maintenance and shortens the operation time. Moreover, there is no need to disassemble the entire valve or replace the integrated components. Only the filter cartridge 9 needs to be replaced, which reduces material waste and accessory costs. It is especially suitable for scenarios where the filter device needs to be cleaned or replaced frequently.
[0046] For a specific embodiment two, please refer to Figure 7-8 Based on the first specific embodiment, a first mounting plate 19 is fixed to the end of the valve body 1 away from the threaded groove 4, and a protective plate 20 is fixed to the side of the valve body 1 away from the threaded groove 4 by bolts; a number of second mounting plates 21 are fixed to the outside of the protective plate 20, and threaded holes 22 are opened on the surface of both the first mounting plate 19 and the second mounting plate 21.
[0047] Specifically, a sealing tube 23 is fixed to the surface of the protective plate 20. The sealing tube 23 is made of rubber material. An adjusting rod 24 passes through the inside of the sealing tube 23. A second handle 25 is fixed to one end of the adjusting rod 24.
[0048] Furthermore, a second spring 26 is fixed between the second handle 25 and the protective plate 20; a baffle 27 is fixed at the end of the adjusting rod 24 away from the second handle 25; the outer wall of the baffle 27 matches the inner wall of the valve body 1.
[0049] The operation process of this embodiment is as follows: When the device is in normal use, under the elastic force of the second spring 26, the baffle 27 is tightly attached to one side of the protective plate 20. At this time, the baffle 27 does not block the inlet 2, and the fluid can flow normally from the inlet 2, be filtered by the filter cartridge 9, and be discharged from the outlet 3. When the filter cartridge 9 needs to be replaced, press the second handle 25 to overcome the elastic force of the second spring 26, drive the adjusting rod 24 to move towards the threaded groove 4, and the adjusting rod 24 pushes the baffle 27 to move synchronously until the outer wall of the baffle 27 is tightly attached to the inner wall of the valve body 1, completely blocking the inlet 2 and cutting off the fluid entry path. This device intercepts the flow before removing the threaded cover 5, avoiding To prevent water leakage when replacing the filter cartridge 9 and facilitate safe operation, this device features a baffle 27. When replacing the filter cartridge 9, pressing the second handle 25 moves the baffle 27 towards the threaded groove 4, causing its outer wall to fit against the inner wall of the valve body 1, temporarily blocking the inlet 2 and cutting off the water flow path. This prevents water leakage when disassembling the threaded cover 5, providing a safe operating environment without water flow for filter replacement. During normal use, the baffle 27, under the elastic force of the second spring 26, adheres tightly to one side of the protective plate 20, separating from the inner wall of the valve body 1, without blocking the inlet 2. This ensures that fluid can flow in and pass through the filter cartridge 9 normally without affecting the valve's filtration and flow functions.
