Description

Technical Field

[0001] This utility model relates to the field of ball valve device technology, and in particular to a novel ball valve core filter device. Background Technology

[0002] In the field of ball valve technology, especially in scenarios such as heating systems and industrial water circulation, ball valves, as key components for controlling the flow of water, often need to be used in conjunction with filter structures to intercept impurities in the water (such as rust, silt, etc.) to prevent impurities from entering subsequent pipe fittings and causing blockage or wear.

[0003] In existing technologies, traditional ball valve filtration devices have many limitations: Firstly, most filters are directly welded or fixedly installed. When the filter becomes clogged and needs to be cleaned or replaced, the entire valve body must be disassembled, which is cumbersome and time-consuming, affecting the system's operating efficiency.

[0004] Secondly, the fixing structure of the filter screen and valve core is not stable enough. Under the impact of high-pressure water flow, it is easy to misalign, deform or even fall off, resulting in filter failure.

[0005] Third, the filtered impurities tend to accumulate inside the valve body, and the lack of convenient impurity discharge channels will reduce filtration efficiency over a long period of time. Summary of the Invention

[0006] The purpose of this invention is to provide a novel spherical valve core filter device, which has a simple structure, is easy to clean, and can filter impurities in circulating water stably over a long period of time.

[0007] To achieve the above objectives, this utility model provides a novel spherical valve core filter device, including a valve body, inside which a spherical valve core and a valve seat are fitted. The top of the spherical valve core is snapped with a valve stem embedded in the valve body. A transversely intercepting filter screen is provided inside the spherical valve core, and a valve bottom cover is movably fixed to the valve body at the bottom of the filter screen.

[0008] Preferably, a valve core inner sleeve is snapped into the spherical valve core, and the filter screen is inserted into the valve core inner sleeve.

[0009] Preferably, both the valve core inner sleeve and the filter screen are integrally "tubular structures", and the portion of the filter screen inserted into the inner side of the valve core inner sleeve is integrally "wedge-shaped", so that the inner cavities of the valve core inner sleeve and the filter screen form a water flow channel.

[0010] Preferably, the inner side of the valve core sleeve has two openings that are inserted into the filter screen.

[0011] Preferably, the valve bottom cover has a through threaded opening in the middle and is threadedly connected to a bottom cover core.

[0012] Therefore, the beneficial effects of this novel spherical valve core filter device are as follows: (1) The valve body has an opening at the bottom, which facilitates the installation and cleaning of the filter screen.

[0013] (2) The ball valve core is inlaid with a valve core inner sleeve to fix the filter screen, so that the filter screen can bear greater thrust.

[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1 like Figure 1 As shown, this utility model provides a novel spherical valve core filter device, including a valve body 1, a spherical valve core 2 and a valve seat 3 are provided inside the valve body 1, and a valve stem 8 embedded in the valve body 1 is snapped onto the top of the spherical valve core 2 to control the angle of the spherical valve core 2, thereby controlling the on / off state of the water flow.

[0020] like Figure 2 As shown, a valve core inner sleeve 4 is snapped into the spherical valve core 2, and a filter screen 5 is inserted into the valve core inner sleeve 4. The filter screen 5 laterally intercepts the water flow channel to filter impurities in the water. The spherical valve core 2 can effectively improve the fixing effect of the filter screen 5 and prevent the filter screen 5 from becoming misaligned under the impact of high-pressure water flow.

[0021] In this embodiment, both the valve core inner sleeve 4 and the filter screen 5 are integrally "tubular structures," and the portion of the filter screen 5 inserted into the inner side of the valve core inner sleeve 4 is integrally "wedge-shaped," such as... Figure 3 As shown, the front end of the filter screen 5 is snapped and fixed to the side wall of the valve core inner sleeve 4, and the rear end of the filter screen 5 is laterally intercepted on the water flow channel of the valve core inner sleeve 4, so that the inner cavity of the valve core inner sleeve 4 and the filter screen 5 form a water flow channel, which facilitates the discharge of filtered impurities from the inside of the valve body 1 later.

[0022] In this embodiment, the inner sleeve 4 of the valve core has two openings on its side for insertion into the filter screen 5, such as... Figure 4 As shown, during installation, simply align one of the openings with filter screen 5, facilitating the snap-fit ​​and securing of filter screen 5. The structure of filter screen 5 is as follows: Figure 5 As shown, the small holes on the side wall of filter screen 5 can filter out impurities while ensuring efficient water flow.

[0023] A valve bottom cover 7 is movably fixed to the valve body 1 at the bottom of the filter screen 5. When cleaning the filter screen 5 is required, the valve bottom cover 7 can be removed to take out the filter screen 5 for cleaning. The valve bottom cover 7 has a through threaded opening in the middle, and a bottom cover core 6 is threadedly connected to it. Figure 6 As shown, a temperature probe can be installed on the bottom cover core 6 to facilitate timely monitoring of the real-time temperature of the circulating water inside the valve body 1.

[0024] Working principle: When the valve is opened, circulating water flows continuously through the ball valve core 2 and the filter screen 5. Larger impurities are blocked by the filter screen 5 and prevented from flowing into other heating system pipes, which can effectively remove impurities in the pipes.

[0025] When the filter screen 5 is severely clogged, the valve stem 8 needs to be rotated to close the ball valve core 2. At this time, a wrench can be used to remove the valve bottom cover 7. After the valve bottom cover 7 is removed, the filter screen 5 can be removed for cleaning. At the same time, the valve stem 8 can be rotated to open the ball valve core 2 and use the heating circulating water for rinsing. After cleaning, the filter screen 5 is inserted into the valve core inner sleeve 4, and then the valve bottom cover 7 is tightened to continue to intercept impurities in the circulating water.

[0026] Therefore, this utility model adopts the above-mentioned novel spherical valve core filter device, which can quickly open the bottom cover without disassembling the entire valve body, so as to remove, clean or replace the filter screen, greatly shorten the maintenance time, reduce the system downtime cost, and make the filter screen less prone to misalignment or deformation under the impact of high pressure water flow, and can withstand greater thrust to ensure long-term stable filtration.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
