Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a plastic tube valve with a built-in filter screen. Background Technology

[0002] In fluid transport systems, especially pipelines involving media such as water, chemical solutions, and gases, valves and filters are two indispensable key components. Valves are used to control the flow and flow regulation of fluids, while filters are used to intercept and remove solid particulate impurities from the fluid to prevent blockage, wear, or corrosion of downstream equipment, thus ensuring the stable and efficient operation of the entire system.

[0003] In the prior art, valves and filters are usually designed, manufactured and installed as two separate components. Separate valves and filters require more installation steps and connections, resulting in a complex and loosely laid-out piping system structure. In space-constrained equipment or compact installation environments, this greatly limits the flexibility of equipment layout.

[0004] Therefore, a plastic tube valve with a built-in filter is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a plastic tube valve with a built-in filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A plastic tube valve with a built-in filter screen, comprising: The valve body has a protruding end at its upper end, and an installation space is provided inside the valve body and the protruding end. The valve body has a mating end a and a mating end b at its two ends, and a second threaded ring is provided inside the mating end b. A valve core component, wherein the valve core component is disposed inside the installation space; The filter element includes filter element a and filter element b, and filter element a and filter element b are respectively detachably disposed inside the docking end a and the docking end b. The filter element a includes a connecting ring, and the connecting ring is hollow and fixedly connected to a filter screen a; The filter element b includes a filter screen b, and a first threaded ring is fixedly connected to the end of the filter screen b. The first threaded ring and a second threaded ring are screwed together.

[0007] As a preferred embodiment of this utility model, the internal cross-sections of both the docking end a and the docking end b are regular octagons, and the interior of the docking end a is provided with an inwardly extending convex ring.

[0008] As a preferred embodiment of this utility model, the mesh diameter of filter screen a is larger than that of filter screen b.

[0009] As a preferred embodiment of this utility model, a docking ring is provided at one end of the inner side of the docking end b, and the docking ring is connected to the pipeline system.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention solves the inherent defects of traditional discrete layouts. The valve body integrates a filtration function, enabling a single component to simultaneously achieve fluid control and impurity filtration. This significantly simplifies the structure of the pipeline system, reduces the requirements for installation space, and provides great flexibility for the layout of compact equipment. This design reduces the number of required connectors, which not only reduces the overall manufacturing and material costs, but also reduces potential leakage points from the source, greatly improving the reliability and safety of system operation.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] Please see Figure 1-4 This utility model provides a technical solution: For an example, please refer to... Figure 1 , 2 1, 2, and 3, a plastic tube valve with a built-in filter, consisting of three main parts: valve body 1, valve core, and filter element.

[0018] The valve body 1, as the main structure of the entire valve, is usually made of engineering plastics such as UPVC, PP or PVDF through one-piece injection molding, which has good corrosion resistance and mechanical strength. The upper end of the valve body 1 is designed with a protruding end 6, which together with the interior of the valve body forms a continuous installation space for accommodating and controlling the movement of the valve core. The two ends of the valve body 1 are respectively provided with mating end a2 and mating end b3 for connecting external pipelines.

[0019] The valve core is installed inside the installation space of the valve body 1 to realize the on-off control of fluid. This is a mature existing technology, and its specific structure will not be described in detail in this embodiment.

[0020] The core improvement of this invention lies in the integration of filtration function. The filter elements include filter element a and filter element b, which are detachably installed inside the docking end a2 and docking end b3, respectively. This design enables the valve to have flow control function while also having impurity interception capability at both interfaces.

[0021] Specifically, the internal cross-sections of the mating ends a2 and b3 are designed as regular octagons. Inside the mating end a2, there is an inwardly extending convex ring 11, while inside the mating end b3, there is a second threaded ring 10.

[0022] The filter element a includes a connecting ring 4, which has a hollow interior and is fixedly connected to a filter screen a5. During installation, the filter element a is inserted from the port of the mating end a2. The outer wall of its connecting ring 4 matches the inner wall of the regular octagon and is fixed by abutment. The convex ring 11 can play a role in axially limiting the filter element a.

[0023] The filter element b includes a filter screen b8, with a first threaded ring fixedly connected to the end of the filter screen b8. During installation, by rotating the filter element b, the first threaded ring at its end is screwed into the second threaded ring 10 inside the mating end b3, thereby firmly and sealingly fixing the filter element b inside the mating end b3.

[0024] As a preferred implementation, the mesh diameter of filter screen a5 is larger than that of filter screen b8. This dual-stage filtration design creates a gradient filtration principle. When fluid flows into the valve from the connecting end a2, it is first initially filtered by filter screen a5, intercepting larger particulate impurities. Subsequently, the fluid flows through the valve core and, after being controlled by the valve, flows to the connecting end b3, where filter screen b8 performs fine filtration, intercepting even smaller particles. This collaborative working model effectively extends the service life of filter screen b8 and improves overall filtration efficiency.

[0025] In addition, a docking ring 9 is provided at one end of the inner side of the docking end b3. The docking ring 9 is used to accurately dock and seal with the pipe joints of the external pipeline system to ensure the reliability and leak-free connection.

[0026] Working principle: This invention achieves a high degree of integration between the valve and the filter by embedding filter element a and filter element b inside the two mating ends of the valve body. During installation, this valve can be connected in series with the pipeline like an ordinary valve to simultaneously perform flow control and bidirectional filtration functions, saving installation space and additional connecting parts, and reducing costs and leakage risks.

[0027] When cleaning or replacing the filter elements is required, the maintenance operation is very simple. For filter element a, it can be directly removed from the mating end a2; for filter element b, it can simply be unscrewed from the second threaded ring 10. The entire process does not require disassembling the entire valve or damaging the piping system, greatly simplifying the maintenance process and improving the maintainability of the equipment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
