[0002] A hemispherical valve is a new type of valve with a hemispherical body and a circular through-hole for media flow. The main features of a hemispherical valve include: excellent sealing performance, employing a metal hard seal or soft seal structure to effectively prevent media leakage; low flow resistance, as the circular ball passage reduces resistance during media flow, minimizing energy loss; strong wear resistance, suitable for applications containing media such as particles and suspended solids, such as ash and slurry conveying systems in mining, metallurgy, and power industries; and long service life, due to its excellent sealing and wear resistance, resulting in a longer overall service life and reduced maintenance and replacement costs.

[0003] Inconvenient disassembly: Current hemispherical valves may have a complex structural design with tightly packed components, lacking convenient disassembly methods. This makes replacement and maintenance time-consuming and labor-intensive for staff, affecting work efficiency and increasing downtime. Insufficient valve stem protection: The valve stem is mostly exposed and lacks effective protection, making it susceptible to impacts from external objects. Once damaged, it not only affects the normal opening and closing of the valve but may also cause safety hazards such as leaks.

[0004] In response to this technical problem, this application proposes a high-temperature resistant hemispherical valve. Utility Model Content

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a high-temperature resistant hemispherical valve, comprising a valve body 4 and a pipe 6. The valve body 4 is made of a high-temperature resistant material, such as WCB or WC9, possessing good strength and high-temperature resistance. A valve stem 9 is provided on the top side of the valve body 4, controlling the opening and closing of the valve body 4. A protective cover 1 is inserted into the top side of the valve body 4 to protect the valve stem 9 from rotation and damage caused by impact from external objects. Valve pipes 5 are fixedly connected to both the left and right sides of the valve body 4, with mounting rings 7 rotatably connected to the ends of the valve pipes 5. A fixing ring 8 is fixedly connected to the end of the pipe 6, with the mounting ring 7 inserted inside the fixing ring 8. The valve pipe 5 and the pipeline 6 are initially connected by inserting the mounting ring 7 into the fixing ring 8. Two fixing plates 3 are fixedly connected to the bottom side of the outer wall of the protective cover 1. Two snap plates 2 are rotatably connected to the top side of the valve body 4. A snap rod 10 is fixedly connected to the bottom side of the snap plate 2. A snap ring 11 is fixedly connected to the outer wall of the snap rod 10. A snap groove is opened on the top side of the fixing plate 3. The snap rod 10 and the snap ring 11 are both engaged in the snap groove. By rotating the snap plate 2, the snap rod 10 and the snap ring 11 are engaged in the snap groove, thereby connecting the snap plate 2 and the fixing plate 3 together, and then fixing the protective cover 1 to the valve body 4.

[0026] Reference Figure 4 and Figure 5The inner wall of the fixing ring 8 has an annular groove 14, and two square grooves 13 are formed on one side of the fixing ring 8. Grooves are formed on both the upper and lower sides of the mounting ring 7. A telescopic rod 15 is fixedly connected inside the groove, and an insertion rod 17 is fixedly connected to the end of the telescopic rod 15. The insertion rod 17 is inserted into the annular groove 14. By inserting the insertion rod 17 into the annular groove 14, the mounting ring 7 is fixed to the fixing ring 8. A lever 18 is fixedly connected to the outer wall of the insertion rod 17. The lever 18 is slidably connected inside the groove, and the lever 18 is used to disengage the insertion rod 17 from the annular groove 14, allowing for telescopic movement. A spring 16 is fitted on the outer wall of the rod 15. One end of the spring 16 is connected to the end of the insertion rod 17, and the other end of the spring 16 is connected to the inside of the groove. The spring 16 is used to press the insertion rod 17 against the annular groove 14. A baffle 19 is slidably connected inside the groove. One end of the baffle 19 is inserted into the groove. By inserting the baffle 19 into the groove, the baffle 19 blocks the paddle 18 to prevent the insertion rod 17 from dislodging from the annular groove 14. A protective cover 12 is inserted into one side of the mounting ring 7. The protective cover 12 protects the baffle 19 to prevent it from loosening due to impact from external objects.

[0027] Working principle: First, place the valve body 4 between the two pipes 6. Then, press the lever 18 to retract the insert rod 17 into the groove. However, due to a special design, a portion of the insert rod 17 remains outside the groove. The length of this portion is equal to the depth of the annular groove 14. Next, rotate the mounting ring 7 to align the insert rod 17 with the square groove 13. Then, insert the insert rod 17 into the square groove 13, causing the mounting ring 7 to insert into the fixing ring 8. Rotate the mounting ring 7 again to rotate the insert rod 17 to the upper and lower sides of the square groove 13, allowing the insert rod 17 to be inserted into the annular groove 14 under the action of the spring 16. This fixes the mounting ring 7 into the fixing ring 8, thus fixing the valve body 4 between the two pipes 6. Finally, slide the baffle 19 to insert it into the groove. This blocks the paddle 18, preventing the insert rod 17 from disengaging from the annular groove 14. Then, the protective cover 12 is inserted into the mounting ring 7 to protect the baffle 19 from external impacts that could cause it to loosen. After that, the protective cover 1 is inserted into the valve body 4. Then, the buckle plate 2 is rotated to engage the buckle rod 10 and the buckle ring 11 into the buckle groove, thereby connecting the buckle plate 2 and the fixing plate 3 together. This fixes the protective cover 1 onto the valve body 4. When it is necessary to rotate the valve stem 9, simply rotate the buckle plate 2 to disengage the buckle rod 10 and the buckle ring 11 from the buckle groove, and then remove the protective cover 1 from the valve body 4 to rotate the valve stem 9. When it is necessary to remove the valve body 4 from the pipe 6, simply repeat the above process in reverse. This will not be elaborated further here.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
