Description

Technical Field

[0001] This utility model relates to the field of ceramic ball valve technology, and in particular to an anti-scaling ceramic ball valve. Background Technology

[0002] Ceramic ball valves are a type of ball valve. Ceramic materials exhibit very low deformation and possess significantly higher bonding strength than metals. Generally, the crystal ions composing ceramic materials have small ionic radii, high ionic valence, and large coordination numbers. These properties determine that ceramic materials possess very high tensile strength, compressive strength, elastic modulus, and hardness. However, the inherent brittleness and difficulty in processing ceramics have limited their applications. In the past decade or so, advancements in martensitic transformation toughening technology, composite material technology, and the concept of nanoceramics have greatly improved the brittleness of ceramics, significantly enhancing their toughness and strength, thus expanding their application range. The application of new ceramic materials in the petroleum, chemical, and machinery industries is very active. Utilizing the wear resistance and corrosion resistance of ceramics to manufacture wear-resistant and corrosion-resistant parts to replace metal materials is one of the important development directions in the high-tech materials market in recent years.

[0003] After a period of use, scale will form on the inner wall surface of a ball valve, gradually accumulating and affecting its performance and service life. To address this problem, we propose an anti-scaling ceramic ball valve. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figure 1-8 A ceramic ball valve for preventing scaling includes a ceramic ball valve body 1 and two connecting shafts 2. The ceramic ball valve body 1 is composed of a ball 1-1, an upper bearing 1-2, a lower bearing 1-3, a valve stem 1-4, an A valve body 1-5, two valve seats 1-6, and two B valve bodies 1-7. It also includes:

[0034] There are two cleaning rings 3. The cleaning rings 3 are located on the left and right sides of the ball 1-1 inside the ceramic ball valve body 1. The cleaning rings 3 are equipped with four scrapers 4 on the side of the ball 1-1 inside the ceramic ball valve body 1 away from the ball 1-1 inside the ceramic ball valve body 1. After the device is installed, the cleaning rings 3 can scrape the ball 1-1 inside the ceramic ball valve body 1 when it rotates, which reduces the probability of scale formation on the ball 1-1 and improves the performance and service life of the ceramic ball valve body 1.

[0035] A support ring 5, there are two A support rings 5, A support ring 5 is fixedly connected to the outside of cleaning ring 3 and A support ring 5 can slide inside the ceramic ball valve body 1;

[0036] Two scraper units 8 are located between the scraper 4 and the connecting shaft 2. Each scraper unit 8 includes a fan blade 81 and several A-connecting rings 82. A B-connecting ring 83 is provided inside the A-connecting ring 82 and is fixedly connected to the outside of the connecting shaft 2. Four support rods 84 are fixedly attached to the inside of the A-connecting ring 82 and the outside of the B-connecting ring 83. The scraper 4 is fixedly connected to the outside of the A-connecting ring 82. Two B-reinforcing blocks 85 are fixed between the outside of the A-connecting ring 82 and the scraper 4. The B-reinforcing blocks 85 improve the connection strength between the A-connecting ring 82 and the scraper 4, making the scraper 4 more... To enhance stability, the fan blade 81 is located inside the B support ring 6 and is installed at one end of the connecting shaft 2. When the ceramic ball valve body 1 is connected to the pipeline, the flow of liquid will drive the fan blade 81 to rotate. The fan blade 81 will rotate along with the B connecting ring 83 through the connecting shaft 2. The B connecting ring 83 will rotate along with the A connecting ring 82 through the support rod 84. The A connecting ring 82 will rotate along with the scraper 4 and scrape the inner wall of the ceramic ball valve body 1, reducing the probability of structural damage to the inner wall of the ceramic ball valve body 1 and improving the service life of the ceramic ball valve body 1.

[0037] B support ring 6, there are two B support rings 6, B support ring 6 is located on one side of A support ring 5 and B support ring 6 is installed inside the ceramic ball valve body 1.

[0038] Connecting part 7, there are two connecting parts 7, located between support ring A 5 and support ring B 6 and connecting shaft 2. Connecting part 7 includes positioning ring A 71 and positioning ring B 72, which are rotatable outside the connecting shaft 2. Four connecting rods A 73 are fixed to the outside of positioning ring A 71, and four connecting rods B 74 are fixed to the outside of positioning ring B 72. Connecting rods A 73 are fixedly connected to the inside of support ring B 6. Connecting block A 75 is fixed to the side of connecting rod B 74 away from connecting rod A 73, and connecting block B 76 is fixed to the side of connecting block A 75. Reinforcing block A 77 is fixed between connecting block A 75 and connecting block B 76. Connecting block B 76 is fixed to the inside of cleaning ring 3. The B support ring 6 supports the A positioning ring 71 via the A connecting rod 73, while the cleaning ring 3 supports the B positioning ring 72 via the B connecting block 76 and the A connecting block 75. The A positioning ring 71 and the B positioning ring 72 position and support the connecting shaft 2, so that the connecting shaft 2 rotates within the A positioning ring 71 and the B positioning ring 72 when the scraper unit 8 rotates. This ensures that the connecting shaft 2 is always on the central axis of the B valve body 1-7 on the ceramic ball valve body 1, allowing the scraper unit 8 to better process the inner wall of the ceramic ball valve body 1. At the same time, the entire assembly is supported by the B support ring 6 and the cleaning ring 3, facilitating replacement and allowing the device to be quickly replaced after a certain period of use.
