Description

Technical Field

[0001] This utility model relates to the field of ball valves, specifically a high-temperature resistant C-type ceramic ball valve assembly. Background Technology

[0002] Ball valves, as one of the most widely used valves, have advantages such as reliable sealing, simple structure, convenient maintenance, and resistance to erosion by the medium. However, when a medium with poor flowability flows through a C-type ball valve, blockages often occur due to the medium's viscosity, tendency to clump, scale, crystallize, or the presence of large particles. This is especially true in the chemical industry, where black water, grey water, and slag water contain ash and high concentrations of calcium and magnesium ions. When fluid temperature and flow rate change, ash deposition and calcium and magnesium salt formation are likely to occur, and erosion and wear are severe. Furthermore, because a dead cavity exists in the central cavity of a metal hard-seal ball valve when it is fully open, and each operating cycle of the equipment exceeds one month, the valve remains in a normally open state. The medium entering the valve's central cavity will stagnate in the dead cavity, resulting in severe scaling on the ball surface. This leads to difficulties in opening and closing, jamming, and serious leakage problems, and may even prevent operation, thus failing to protect the pump. Basically, the valve needs to be disassembled and cleaned after one operating cycle, and replaced after two cycles.

[0003] To address the aforementioned issues, a search revealed Chinese patent CN217401762U, which discloses a C-type ball valve with a ceramic-reinforced structure. The patent includes a ceramic sealing pair between a C-type valve core and a valve seat within the valve body. This ceramic sealing pair consists of a ceramic spherical crown on the convex surface of the C-type valve core and a ceramic bushing on the valve seat. The ceramic bushing is formed by a closed loop with an arc cross-section, and its curvature matches the contour of the convex surface of the ceramic spherical crown. The ceramic spherical crown and the C-type valve core, as well as the ceramic bushing and the valve seat, are joined using either a heat-fitting process or an adhesive bonding process.

[0004] Although the above-mentioned device has good resistance to torsional and shear forces, and possesses the advantages of high reliability of metal and high erosion and corrosion resistance of ceramic materials, in actual use, when water flows through, impurities in the water settle inside the ball valve. The accumulation of impurities may jam the ball or valve stem, making it difficult to open or close the valve, or even preventing it from opening and closing normally. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant C-type ceramic ball valve assembly to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a high-temperature resistant C-type ceramic ball valve assembly is provided, comprising a ball valve body, an inlet pipe fixedly disposed at the end of the ball valve body, a support base fixedly disposed at the bottom of the ball valve body, a stabilizing plate fixedly disposed at the bottom of the support base, and a ball valve anti-blocking assembly installed on the inlet pipe. The ball valve anti-blocking assembly includes an agitator tube fixedly connected to the inlet pipe via a flange, a shaft movably disposed inside the agitator tube, an agitator impeller disposed on the outer circumference of the shaft, a bearing seat disposed at the end of the shaft, and a support frame disposed on the outer circumference of the bearing seat.

[0007] Preferably, support seats are fixedly provided on both sides of the bottom of the ball valve body. The support seats are arranged in a "Y" shape. The bottom of both sets of support seats are mounted on a stabilizing plate, and the stabilizing plate has slots.

[0008] Preferably, the ball valve anti-blocking assembly includes an agitator tube, an agitator space, a shaft, an agitator impeller, a bearing seat, a support frame, a connecting rod, and a scraper seat, with connecting flanges fixedly installed at both ends of the agitator tube.

[0009] Preferably, the agitator impeller on the outer circumference of the shaft is arranged in a spiral shape. The agitator impeller rotates under the impact of the water flow inside the agitator tube, and the length of the agitator impeller is equal to four-fifths of the length of the agitator tube.

[0010] Preferably, bearing seats are installed at both ends of the shaft, and the support frame outside the bearing seats consists of three sets of equidistant connecting rods, with the ends of the connecting rods fixedly connected to the inner wall of the stirring tube.

[0011] Preferably, three sets of connecting rods are linearly installed on the outer circumference of the shaft, and each of the three sets of connecting rods is fixedly connected to a scraper seat. The distance between the scraper seat and the inner wall of the stirring tube is 1-2 mm, and the stirring tube has a stirring space inside.

[0012] Preferably, the inner diameter of the agitator tube is the same as the inner diameter of the inlet pipe, the scraper seat is rectangular, and the three sets of scraper seats are driven to rotate by a shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses water flow to impact the agitator impeller, causing the impeller to rotate. Simultaneously, the shaft rotates, and the shaft, through three sets of connecting rods, drives three sets of scraper seats to rotate. This allows the scraper seats to agitate the particulate sediment deposited at the bottom of the agitator tube and suspend it in the water, making it easier for it to pass through the ball valve body. It also prevents sediment from settling inside the ball valve body and thus avoids clogging the ball valve body.

[0015] 2. This utility model uses water flow to impact a spiral agitator impeller, causing it to rotate and drive a shaft to rotate. The shaft, through a connecting rod, drives a scraper seat to rotate, which can agitate and suspend particulate sediment deposited at the bottom of the agitator tube in the water. No additional power is required; it can work continuously using the kinetic energy of water flow. This not only prevents valve jamming, sealing failure, and wear caused by impurity accumulation, but also improves the smoothness of fluid transport, reduces maintenance frequency, and ensures the long-term stable operation of the ball valve body.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6This utility model provides a high-temperature resistant C-type ceramic ball valve assembly, including a ball valve body 1, an inlet pipe 2 fixedly installed at the end of the ball valve body 1, a support base 3 fixedly installed at the bottom of the ball valve body 1, a stabilizing plate 31 fixedly installed at the bottom of the support base 3, a ball valve anti-blocking assembly 4 installed on the inlet pipe 2, the ball valve anti-blocking assembly 4 including an agitator tube 40 fixedly connected to the inlet pipe 2 through a flange, a shaft 42 movably installed inside the agitator tube 40, an agitator impeller 421 installed on the outer circumference of the shaft 42, a bearing seat 43 installed at the end of the shaft 42, and a support frame 44 installed on the outer circumference of the bearing seat 43.

[0025] Working principle: When in use, the water flows into the ball valve body 1 through the anti-blocking component 4. The ball valve body 1 is used for conveying or blocking. When the water flows into the anti-blocking component 4, it impacts the agitator impeller 421. The agitator impeller 421 is spirally designed, causing it to rotate. At the same time, it drives the shaft 42 to rotate. When the shaft 42 rotates, it drives the three sets of scraper seats 46 to rotate through the three sets of connecting rods 45. This allows the scraper seats 46 to agitate the particulate sediments deposited at the bottom of the agitator tube 40 and suspend them in the water. This makes it easier for the water to pass through the ball valve body 1 and prevents it from settling inside the ball valve body 1, thus avoiding blockage.

[0026] The water flow impacts the spiral agitator impeller 421, causing it to rotate and driving the shaft 42 to rotate. The shaft 42 drives the scraper seat 46 to rotate via the connecting rod 45. This agitates and suspends particulate sediment deposited at the bottom of the agitator tube 40 in the water, preventing it from accumulating inside the ball valve body 1 and causing blockage. Automatic agitation and sludge removal are achieved through mechanical transmission, requiring no additional power. It can work continuously using the kinetic energy of the water flow. This not only prevents valve jamming, sealing failure, and wear caused by impurity accumulation, but also improves the smoothness of fluid transport, reduces maintenance frequency, and ensures the long-term stable operation of the ball valve body 1. At the same time, the compact structure is closely integrated with the water passage of the ball valve, without affecting the normal interception and transport functions, and effectively enhances the ball valve's ability to resist impurity deposition.

[0027] As a preferred embodiment, support seats 3 are fixedly installed on both sides of the bottom of the ball valve body 1. The support seats 3 are arranged in a "Y" shape. The bottom of both sets of support seats 3 are installed on the stabilizing plate 31, and the stabilizing plate 31 has slots 32.

[0028] When the ball valve body 1 is in operation, it can be screwed onto the pre-designed anchor bolts at the installation position through the slot 32 on the bottom stabilizing plate 31. This prevents the ball valve body 1 from shaking during operation, ensuring its stability. The screw connection between the slot 32 and the anchor bolts allows for quick installation of the ball valve body 1 to the preset position. The screw connection provides strong connection force, ensuring the ball valve body 1 is firmly fixed and preventing operational issues due to loose connections. Direct connection between the stabilizing plate 31 and the anchor bolts provides reliable support for the ball valve body 1 from the bottom, counteracting vibrations and external forces that may occur during operation, greatly reducing the risk of shaking and maintaining a stable working state. This stable installation allows the ball valve body 1 to accurately perform opening, closing, and adjustment functions during operation, reducing component wear and sealing failure caused by shaking, improving the overall performance and reliability of the ball valve, and extending its service life.

[0029] In a preferred embodiment, the ball valve anti-blocking assembly 4 includes an agitator tube 40, an agitator space 41, a shaft 42, an agitator impeller 421, a bearing seat 43, a support frame 44, a connecting rod 45, and a scraper seat 46. Both ends of the agitator tube 40 are fixedly provided with connecting flanges.

[0030] In a preferred embodiment, the agitator 421 on the outer circumference of the shaft 42 is arranged in a spiral shape. The agitator 421 rotates under the impact of the water flow inside the agitator tube 40. The length of the agitator 421 is equal to four-fifths of the length of the agitator tube 40.

[0031] In a preferred embodiment, bearing seats 43 are installed at both ends of the shaft 42. The support frame 44 on the outside of the bearing seat 43 consists of three sets of equidistant connecting rods, and the ends of the connecting rods are fixedly connected to the inner wall of the stirring tube 40.

[0032] In a preferred embodiment, three sets of connecting rods 45 are linearly installed on the outer circumference of the shaft 42. Each of the three sets of connecting rods 45 is fixedly connected to a scraper seat 46. The distance between the scraper seat 46 and the inner wall of the stirring tube 40 is 1-2 mm. The stirring tube 40 has a stirring space 41 inside.

[0033] In a preferred embodiment, the inner diameter of the agitator tube 40 is the same as the inner diameter of the water inlet tube 2, and the scraper seat 46 is rectangular. The three sets of scraper seats 46 are driven to rotate by the shaft 42.

[0034] 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.
