Description

Technical Field

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

[0002] Valves, as key control components in fluid transport systems, are widely used in petrochemical, water supply and heating, and industrial manufacturing fields, undertaking the core functions of regulating flow, cutting off media, and ensuring the safe operation of the system. Traditional valve structures consist mainly of a valve body, valve core, and drive mechanism, integrated into the pipeline via flanges or threaded connections. With the increasing complexity of industrial systems, valves face higher requirements in terms of pressure resistance, sealing performance, and functional integration; their performance directly affects pipeline stability and maintenance efficiency.

[0003] However, existing valves generally lack built-in filtration capabilities, making it impossible to directly intercept impurities in the fluid (such as particulate matter and rust). In practical applications, an additional independent filter must be installed upstream of the valve, resulting in a bulky piping structure, increased installation costs, and potential leakage risks at the junctions of multiple devices. During long-term operation, impurities tend to accumulate in the valve cavity or adhere to the sealing surface, causing valve jamming, seal failure, and even wear of critical components. Although some improved designs attempt to add a filtration structure inside the valve body, these often suffer from problems such as inconvenient filter replacement, low filtration efficiency, or unreasonable cavity design, making it difficult to achieve a balance between ease of maintenance and filtration performance. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a valve with a filtering function.

[0005] To achieve the above objectives, the technical solution of this utility model is a valve with a filtering function, including a valve body, flanges at both ends of the valve body, a filter cavity machined on the valve body, a sealing cover installed at the upper opening of the filter cavity, and a removable and replaceable filter screen structure inside the filter cavity.

[0006] The filter chamber is a flat shell machined in the middle of the valve body. The internal shape of the filter chamber is U-shaped. The size and shape of the filter screen structure match the size and shape of the internal shape of the filter chamber.

[0007] The filter structure is a box-shaped structure formed by bending the edge to one side. The bottom surface of the filter structure is U-shaped, and the side surface of the filter structure can fit into the inner surface of the filter cavity.

[0008] A retaining edge is provided on one side edge of the filter structure, and the retaining edge is distributed in the arc-shaped section of the side of the filter structure.

[0009] The filter holes of the filter structure are distributed on the bottom surface and the edge of the filter structure.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This application adopts an integrated filtration function. By directly machining a U-shaped filter cavity on the valve body and incorporating a removable filter structure, the valve and filter unit are structurally integrated, saving the space and cost of an external filter and reducing the risk of pipeline connection leakage.

[0012] 2. This application adopts a high-efficiency directional filtration design. The filter screen structure and the filter chamber adopt a U-shaped cross-section matching structure, combined with the design of the baffle and side openings, so that the fluid forms a multi-directional filtration path when flowing through the valve body, which significantly improves the impurity interception efficiency and avoids the pressure loss problem caused by unilateral blockage of the filter screen structure.

[0013] 3. This application improves maintenance convenience through modular design. The filter screen structure adopts a box-shaped detachable structure, combined with the sealing cover design with an opening at the top. The filter screen structure can be cleaned or replaced quickly without disassembling the valve body, which greatly reduces the difficulty of maintenance operations and system downtime, and extends the service life of the valve.

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-6 As shown;

[0022] The inventive point of this application is that a filter chamber 4 is machined on the valve body 1, the upper end of the filter chamber 4 is provided with an opening, a detachable sealing cover 5 is installed at the opening, and a detachable and replaceable filter screen structure 6 is provided inside the filter chamber 4, which can filter the fluid inside the valve body 1.

[0023] It should be noted that the filter chamber 4 is a flat shell machined in the middle of the valve body 1. The filter chamber 4 is arranged radially along the valve body 1, and the plane of the filter chamber 4 can be perpendicular to the axial direction of the valve body 1. The internal shape of the filter chamber 4 is U-shaped. The size and shape of the filter screen structure 6 match the internal size and shape of the filter chamber 4. When the sealing cover 5 is installed on the upper opening of the filter chamber 4, it can seal the filter screen structure 6 inside the filter chamber 4 and make the contact part between the filter screen and the filter chamber 4 fit together.

[0024] The inventive point of this application is that the filter structure 6 is a box-shaped structure formed by bending the edge to one side. The bottom surface of the filter structure 6 is U-shaped. The shape and size of the bottom surface of the filter structure 6 match the shape and size of the longitudinal section of the filter cavity 4. The side surface of the filter structure 6 can fit against the inner surface of the filter cavity 4. A retaining edge 7 is provided at one edge of the side surface of the filter structure 6 (this edge is consistent with the side where the edge of the filter structure 6 is bent). The retaining edge 7 is parallel to the bottom surface of the filter structure 6. The retaining edge 7 is distributed on the arc-shaped section of the side surface of the filter structure 6. The filter holes 8 of the filter structure 6 are distributed on the bottom surface of the filter structure 6 and the retaining edge 7. The filter holes 8 of the filter structure 6 can also be distributed on the side surface of the filter structure 6.

[0025] During the implementation of this application, staff only need to remove the sealing cover 5 to directly replace the filter structure 6 inside the filter chamber 4. The maintenance difficulty is low and the maintenance process is simple and convenient.
