Description

Technical Field

[0001] This utility model relates to the field of valve ball technology, and in particular to a valve body for a flanged ball valve with a handle. Background Technology

[0002] In modern industrial production, municipal water supply and drainage, and various fluid transport systems, valves play a crucial role as key components controlling fluid flow. Flanged ball valves, with their advantages of good sealing performance, low flow resistance, and ease of operation, are widely used in various pipeline systems. The valve body of a flanged ball valve with a handle, as its core component, directly affects the valve's performance and service life. Its performance not only relates to the stability and safety of fluid transport but also has a significant impact on the overall system's operating efficiency and maintenance costs.

[0003] Currently, traditional flanged ball valves with handles present numerous problems in practical use. Regarding ball fixation, some valve bodies employ simplistic fixing methods, making the ball prone to accidental rotation due to external vibration or misoperation after closure. This can cause the valve to fail to maintain its closed state, resulting in uncontrolled water leakage. For example, in industrial environments with significant vibration, the ball in traditional valve bodies can gradually loosen, leading to media leakage in the pipeline. This not only wastes resources but may also cause safety accidents. Furthermore, the design of traditional valve bodies is inadequate in terms of the connecting plate and handle maintenance. The connecting plate and handle are prone to damage after prolonged use, and replacement is extremely cumbersome. It typically requires disassembling multiple parts, consuming significant time and manpower, which reduces production efficiency and increases maintenance costs. Moreover, during reinstallation, the lack of precise positioning and a stable fixing structure can cause the connecting plate to loosen after installation, affecting the flexibility and stability of the handle operation, thus impacting the normal use of the valve. In addition, traditional valve bodies also have certain sealing defects. After long-term use, the sealing performance between the ball and the pipeline deteriorates, exacerbating leakage problems. Therefore, it is urgent to develop a valve body with a handle flange that can effectively fix the valve ball, facilitate the replacement of connecting plates and handles, and has good sealing performance. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a valve body for a flanged ball valve with a handle. This invention aims to solve problems such as the valve ball being prone to accidental rotation and the inconvenience of replacing the connecting plate and handle in a flanged ball valve with a handle, thereby improving the performance and safety of the valve body.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flanged ball valve body with a handle includes a valve body with a pipe inside. A valve ball is rotatably connected inside the pipe. A connecting rod is fixedly connected to the top side of the valve ball, passing through the pipe and the valve body. A positioning element is fixedly connected to the top side of the connecting rod. A threaded groove is formed on the top side of the positioning element, and a fixing component is provided inside the threaded groove. A mounting block is fixedly connected to the left end of the top side of the valve body. A fixing groove is formed on the right end of the rear side of the mounting block. A lifting groove is formed on the top side of the fixing groove, and a limit component is provided inside the lifting groove. A connecting piece is provided on the top side of the valve body. A fixing rod is fixedly connected to the rear side of the connecting piece, and a handle is fixedly connected to the right side of the connecting piece.

[0007] Furthermore, the limiting component includes a limiting block, which is slidably connected inside the lifting groove, and a lifting rod is fixedly connected to the top side of the limiting block, with the top side of the lifting rod penetrating through the top side of the mounting block.

[0008] Furthermore, a knob is rotatably connected to the top side of the mounting block, the top side of the lifting rod passes through the top side of the knob, and the top end of the outer wall of the knob is threadedly connected to the inner wall of the knob.

[0009] Furthermore, the fixing component includes a screw, the bottom side of which has a spring groove, a spring is disposed inside the spring groove, one end of the spring is fixedly connected to the top side of the spring groove, and the other end is fixedly connected to an abutment block, the abutment block being slidably connected inside the spring groove.

[0010] Furthermore, the connecting piece has a through hole inside and a positioning groove on its bottom side.

[0011] Furthermore, the bottom end of the screw penetrates the through hole, and the bottom side of the outer wall of the screw is threadedly connected to the inner wall of the threaded groove.

[0012] Furthermore, the positioning element is located inside the positioning groove.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, after use, rotating the knob moves the lifting rod and the limiting block upwards. After rotating the handle to cut off the water flow, rotating the knob in the opposite direction resets the lifting rod and the limiting block and fixes the fixing rod, thereby preventing the valve ball from rotating. This design effectively avoids water loss control problems caused by accidental rotation of the valve ball, ensures the stable operation of the pipeline system, reduces safety risks, and is especially suitable for occasions with strict water flow control requirements.

[0015] 2. In this utility model, when the connecting piece or handle malfunctions, the connecting piece can be easily removed and replaced by turning the screw. When installing a new connecting piece, the positioning component precisely positions itself within the positioning groove. During screw installation, the abutment block compresses the spring; after installation, the spring pushes the screw, ensuring a tight fit between the screw and the threaded groove, thus more firmly securing the connecting piece. This not only facilitates equipment maintenance but also enhances the stability of the connecting piece and extends the service life of the valve body. Attached Figure Description

[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] Reference Figure 1-3This utility model provides an embodiment of a flanged ball valve body with a handle, comprising a valve body 1, an internal pipe 2, a valve ball 9 rotatably connected inside the pipe 2, a connecting rod 8 fixedly connected to the top side of the valve ball 9 passing through the pipe 2 and the valve body 1, a positioning member 17 fixedly connected to the top side of the connecting rod 8, a threaded groove 18 formed on the top side of the positioning member 17, a screw 5 disposed inside the threaded groove 18, a mounting block 3 fixedly connected to the left end of the top side of the valve body 1, and a fixing groove 12 formed on the right end of the rear side of the mounting block 3. A lifting groove is provided on the top side, and a limit block 11 is provided inside the lifting groove. A connecting piece 6 is provided on the top side of the valve body 1. A fixing rod 13 is fixedly connected to the rear side of the connecting piece 6. A handle 7 is fixedly connected to the right side of the connecting piece 6. The limit block 11 is slidably connected inside the lifting groove. A lifting rod 10 is fixedly connected to the top side of the limit block 11. The top side of the lifting rod 10 passes through the top side of the mounting block 3. A knob 4 is rotatably connected to the top side of the mounting block 3. The top side of the lifting rod 10 passes through the top side of the knob 4. The top of the outer wall of the knob 4 is threadedly connected to the inner wall of the knob 4.

[0025] Specifically, after using the ball valve body with a handle flange, first turn knob 4. Since the limit block 11 cannot rotate within the lifting groove, the knob drives the lifting rod 10 and the limit block 11 to move upward. Next, turn handle 7, causing the connecting piece 6 and the fixing rod 13 to rotate. Since the positioning piece 17 is within the positioning groove 19, it further drives the connecting rod 8 and the valve ball 9 to rotate, cutting off the water flow in the pipe 2, while simultaneously allowing the fixing rod 13 to enter the fixing groove 12. Then, turn knob 4 in the opposite direction to reset the lifting rod 10 and the limit block 11 and fix the fixing rod 13, preventing the valve ball 9 from rotating.

[0026] Reference Figure 1 , Figure 4 and Figure 5 The bottom side of the screw 5 has a spring groove, and a spring 14 is installed inside the spring groove. One end of the spring 14 is fixedly connected to the top side of the spring groove, and the other end is fixedly connected to an abutment block 15. The abutment block 15 is slidably connected inside the spring groove. The inside of the connecting piece 6 has a through hole 16, and the bottom side of the connecting piece 6 has a positioning groove 19. The bottom end of the screw 5 passes through the through hole 16, and the bottom side of the outer wall of the screw 5 is threadedly connected to the inner wall of the thread groove 18. The positioning element 17 is located inside the positioning groove 19.

[0027] Specifically, when the connecting piece 6 has been used for a long time or the handle 7 is damaged, turn the screw 5 to remove it, release the limiting effect on the connecting piece 6, and then remove it. Place the new connecting piece 6 on the top side of the valve body 1, allow the positioning part 17 to enter the positioning groove 19, and reinstall the screw 5. During installation, the abutment block 15 first contacts the bottom side of the threaded groove 18 to compress the spring 14. After installation, the spring 14 applies force through the abutment block 15, making the screw 5 tightly fit with the thread of the threaded groove 18, thus more firmly fixing the connecting piece 6.

[0028] Working principle: After use, first turn knob 4. Since the limit block 11 is located inside the lifting groove and cannot rotate, turning knob 4 will drive the lifting rod 10 and the limit block 11 to move upward. Then, turn handle 7 to drive the connecting piece 6 and the fixing rod 13 to rotate. Since the positioning piece 17 is located inside the positioning groove 19, turning handle 7 will simultaneously drive the connecting rod 8 and the valve ball 9 to rotate, thereby cutting off the water flow inside pipe 2 through the valve ball 9. At the same time, turning handle 7 will cause the fixing rod 13 to enter the fixing groove 12. Then, turn knob 4 in the opposite direction to make the lifting rod 10 drive the limit block 11 to reset, thereby fixing the fixing rod 13 and preventing the valve ball 9 from rotating. The connecting piece 6... If the screw 5 is used for too long or the handle 7 is damaged, the screw 5 can be removed by turning the screw 5, which will release the limit on the connecting piece 6. Then the connecting piece 6 can be removed and placed on the top side of the valve body 1. At the same time, the positioning piece 17 will enter the interior of the positioning groove 19. Then the screw 5 can be reinstalled. During the installation of the screw 5, the abutment block 15 will first contact the bottom side of the thread groove 18 and compress the spring 14. After the installation is completed, the spring 14 will continuously exert force on the bottom of the thread groove 18 through the abutment block 15, thereby pushing the screw 5 to move upward, so that the threads on the outer wall of the screw 5 fit more tightly with the threads on the inner wall of the thread groove 18, thereby making the screw 5 more firmly fixed to the connecting piece 6.

[0029] 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.
