Description

Technical Field

[0001] The utility model relates to the technical field of heating valves, in particular to a heating valve with a filtering mechanism. Background Art

[0002] A heating valve with a filtering mechanism is a valve device that integrates a filtering function. It can intercept and filter solid particles, impurities, etc. in the fluid during the fluid heating process to protect the normal operation of pipelines and equipment and prevent blockage or damage to equipment due to impurities. This valve is usually used in systems that require strict control of fluid cleanliness, such as chemical, food and beverage, and pharmaceutical industries. During use, the fluid first passes through the filter, and the intercepted impurities are removed by regular cleaning or replacement of the filter, while the clean fluid can pass through the valve and flow to the next process. Through such a design, the heating valve can not only play a role in temperature control, but also ensure the cleanliness of the fluid when it flows through the pipeline, extend the service life of the equipment, and ensure the stable operation of the system.

[0003] According to the search of China Utility Model Publication No.: CN216643141U, a valve with a filter mechanism inside is disclosed. 1. The valve with a filter mechanism inside is provided with a mounting mechanism. Under the rotation of the first rotating block, the fixed block connected to one end of the first threaded rod can be moved to the two ends of the pipe according to the size of the pipe, and then the threaded shaft is rotated to fit the clamping block to the outer wall of the pipe, so that the pipe is firmly installed, and the operation is simple, which is convenient to improve the practicality of the valve; 2. The valve with a filter mechanism inside is provided with a filter mechanism. Through the setting of the filter mechanism, under the action of the mutual cooperation between the movable block and the movable hook, the filter net can be firmly connected, which is convenient for filtering the circulating liquid, blocking larger impurities, and avoiding subsequent circulation from being hindered; 3. The valve with a filter mechanism inside is provided with a filter mechanism. Through the setting of the adsorption mechanism, under the action of the mutual cooperation between the second card slot and the second card block, the adsorption plate can be firmly connected, which is convenient for adsorption and filtration of the circulating liquid, adsorption of impurities in the liquid, avoiding endangering the life and health of the user, and improving the versatility of the valve.

[0004] However, there are some problems that need to be considered when implementing the above technical solution: after the filter is clogged, the valve is inconvenient to clean and needs to be stopped for cleaning, which is complicated to operate and leads to reduced work efficiency. The flat filter is easily clogged. Secondly, it is inconvenient to understand the working condition of the filter and filter blockage cannot be discovered in time. Utility Model Content

The rotating seat 304 is rotated to switch the filter box 306. The protrusion can increase the friction and facilitate the rotation of the rotating seat 304.

[0028] Specifically, filter boxes 306 are arranged on both sides of the rotating shaft 305, and two groups of filter boxes 306 are arranged. Sealing gaskets 307 are arranged on the left and right sides of the filter boxes 306. The two filter boxes 306 work in turn. When one filter box 306 is working, the other filter box 306 can be cleaned, thereby reducing the valve closing time and improving the flow efficiency.
