Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a high-performance eccentric hemispherical valve for mud applications with flow obstruction. Background Technology

[0002] Traditional valves present numerous problems when handling mud. For instance, in the long-term contact with mud, the ball and seat of ordinary ball valves are easily eroded and worn by mud particles, leading to decreased sealing performance and leakage. This can affect normal production and potentially cause environmental pollution. Furthermore, due to the high viscosity of mud, ordinary valves require significant operating force to open and close, increasing the labor intensity of operators and potentially damaging valve components, thus shortening the valve's service life.

[0003] To address these issues, some high-performance valve products have gradually emerged in the market. However, some existing high-performance valves still have shortcomings in structural design and lack effective maintenance methods. For example, key valve components such as sealing parts and rotating parts are prone to wear and jamming due to long-term operation in harsh mud environments. However, there are no corresponding convenient maintenance devices to lubricate and maintain these parts in a timely manner, thus affecting the overall performance and service life of the valve.

[0004] Publication number: CN215568100U. When the valve ball rotates, its surface contacts the arc-shaped scraper. The arc-shaped scraper removes the residue on the surface of the valve ball, achieving automatic cleaning and preventing residue from adhering to the surface of the valve ball, thus ensuring the sealing between the valve ball and the valve seat.

[0005] To address the aforementioned issues, traditional valves are susceptible to wear from mud particles, making them difficult to maintain and reducing their lifespan. Therefore, we propose a high-performance eccentric hemispherical valve for mud applications with a flow-blocking design. Utility Model Content

[0029] Furthermore, the outer bottom end of the long rod 9 is fixedly connected to the inside of the baffle 13, the top of the spring 12 is fixedly connected to the top wall of the connecting post 10, and the bottom of the spring 12 is fixedly connected to the top of the baffle 13.

[0030] Furthermore, a one-way valve 16 is fixedly installed on the outer side of the connecting column 10, and a connecting pipe 2 14 is fixedly connected to the outside of the one-way valve 16. An oil tank 15 is fixedly connected to the bottom of the connecting pipe 2 14, and the outside of the oil tank 15 is fixedly installed on the outside of the protective pipe 1.

[0031] Structural Description: Protective Pipe 1: The protective pipe is cylindrical in shape and serves as the external protective structure for the entire valve. It has a pipe 5 fixedly connected inside to provide a channel for the flow of mud. Both ends of the protective pipe are equipped with flanges 4, and each flange 4 is connected to the external pipe by multiple bolts and nuts. This connection method allows the valve to be securely installed in the mud conveying system and facilitates disassembly and maintenance. In addition, the top of the protective pipe has a hole for installing connecting pipe 2.

[0032] Connecting pipe 12: The connecting pipe is fixedly connected to the top of the protective pipe 1, and a fixing post 3 is fixedly installed on its top. Connecting pipe 12 is a key component for connecting the internal and external conveying components of the valve. It provides a channel for the conveying of the maintenance medium and also plays a certain role in structural support.

[0033] Fixed column 3: The fixed column is installed on the top of the connecting pipe 2. Its outer surface is fixed by multiple bolts and nuts. An iron block is fixedly installed in the center of the top. The fixed column 3 further enhances the stability of the connecting pipe 2 and provides a mounting base for possible external operating components such as the connection with the drive device.

[0034] Flange 4: There are two flanges 4, which are installed at both ends of the outer side of the protective pipe 1. The outer surface of the flange is provided with multiple bolt holes, which are connected to the external pipe through bolts and nuts to realize the connection between the valve and the entire mud conveying pipeline system. A hole is opened in the center of the outer side of the flange, which is connected to the pipe 5 inside the protective pipe 1 to ensure that the mud can smoothly enter and exit the valve.

[0035] Pipeline 5: The pipeline is fixed inside the protective pipe 1. Its interior is hollow and serves as the main channel for mud flow. A hole is opened at the top of the pipeline 5 for installing a crossbar. A rotating shaft 8 is rotatably connected to the crossbar. In addition, a fixing ring 6 is fixedly installed inside the pipeline 5. A hole is opened in the center of the fixing ring 6, which communicates with the internal space of the pipeline 5. The piston 7 is externally engaged inside the fixing ring 6 to control the flow and blockage of mud.

[0036] Fixed ring 6: The fixed ring is fixedly installed inside the pipe 5. The hole in the center of the ring is aligned with the channel of the pipe 5. The piston 7 can be engaged inside the fixed ring 6. The valve can be opened and closed by changing the relative position of the piston 7 and the fixed ring 6 to make them fit together or stagger.

[0037] Piston 7: The bottom of the piston is fixedly connected to the rotating shaft 8. With the rotation of the rotating shaft 8, the piston 7 can rotate inside the fixed ring 6. When the piston 7 is in contact with the fixed ring 6, it can block the mud from passing through. When the piston 7 is misaligned with the fixed ring 6, the mud can flow in the pipe 5 through the holes inside the fixed ring 6.

[0038] Rotating shaft 8: The rotating shaft is rotatably connected to the crossbar at the top of the pipe 5, and its bottom is fixedly connected to the piston 7. The operator rotates the rotating shaft 8 to drive the piston 7 to rotate, thereby realizing the opening and closing of the valve.

[0039] Long rod 9: The long rod is slidably connected to the center of the connecting column 10, and its bottom end is fixedly connected to the inside of the baffle 13. Under the action of the spring 12, the long rod 9 can move up and down inside the connecting column 10 to control the delivery of the maintenance medium.

[0040] Connecting column 10: The connecting column is fixedly connected to the outside of the connecting pipe 2. Its interior is hollow and is used to accommodate components such as the long rod 9, spring 12, and baffle 13. One end of the connecting column 10 is fixedly connected to the outlet 11. The outlet 11 is fixedly connected to the top of the crossbar, so that the maintenance medium can be delivered to the part inside the valve that needs maintenance through the outlet 11. In addition, a one-way valve 16 is fixedly installed on one side of the connecting column 10 to control the one-way flow of the maintenance medium.

[0041] Outlet 11: The outlet is fixedly connected to one end of the connecting column 10 and connected to the top of the crossbar. The outlet 11 is the channel through which the maintenance medium flows out of the connecting column 10 and into the valve, delivering the maintenance medium to components such as the rotating shaft 8 and piston 7 for lubrication and maintenance.

[0042] Spring 12: The spring is sleeved on the outside of the long rod 9. Its top is fixedly connected to the top wall of the connecting column 10, and its bottom is fixedly connected to the top of the baffle 13. The spring 12 provides elastic force to the long rod 9, so that the long rod 9 can return to its initial position when it is not subjected to external force, thus ensuring the normal operation of the conveying component.

[0043] Baffle 13: The baffle is fixedly installed at the bottom of the inner part of the connecting column 10. It is used to fix the bottom of the long rod 9 and to provide support for the spring 12 so that the spring 12 can function properly.

[0044] Connecting pipe 2 14: One end of the connecting pipe is fixedly connected to the outside of the one-way valve 16, and the other end is connected to the top of the oil tank 15. Connecting pipe 2 14 is a medium conveying channel between the oil tank 15 and the connecting column 10, used to convey the maintenance medium in the oil tank 15 to the connecting column 10.

[0045] Oil tank 15: The oil tank is fixedly installed outside the protective pipe 1 and is used to store maintenance media such as lubricating oil. The oil tank 15 is connected to the connecting column 10 through the connecting pipe 2 14 to provide a medium source for valve maintenance.

[0046] One-way valve 16: The one-way valve is fixedly installed on the outside of the connecting column 10. Its function is to ensure that the maintenance medium can only flow from the oil tank 15 into the connecting column 10 through the connecting pipe 2 14 in one direction, preventing impurities such as mud from entering the oil tank 15 and the connecting pipe 2 14, and ensuring the cleanliness of the maintenance medium and the reliability of its transportation.

[0047] When the high-performance eccentric hemispherical valve for slurry flow control is put into use, the slurry enters the valve's internal pipe 5 through the pipe connected to the flanges 4 at both ends of the protective pipe 1. With the valve open, the rotating shaft 8 connected to the top crossbar of pipe 5 drives the piston 7 to rotate, causing the piston 7 to be misaligned with the fixed ring 6. At this time, the central hole inside the fixed ring 6 is unobstructed, allowing the slurry to pass smoothly through pipe 5. Because the piston 7 is externally engaged inside the fixed ring 6, this structure can prevent slurry leakage to a certain extent. When the valve needs to be closed, the operator rotates the rotating shaft 8, causing the piston 7 to rotate until it is in contact with the fixed ring 6, thereby blocking the slurry and achieving the valve's closing function. During the daily use of the valve, the conveying component plays a role in maintaining the ball valve, mainly the key internal parts. Inside the connecting column 10 outside the connecting pipe 12, the long rod 9 can slide up and down under the action of the spring 12. When internal maintenance of the valve is required, such as adding lubricating oil or other maintenance media, it is used. The maintenance medium enters the connecting column 10 from the oil tank 15 through the connecting pipe 14. Since a one-way valve 16 is installed on one side of the connecting column 10, the maintenance medium can only enter the connecting column 10 in one direction, preventing impurities such as mud from entering the oil tank 15 and the connecting pipe 14. The maintenance medium entering the connecting column 10 pushes the long rod 9 downward to compress the spring 12. The maintenance medium flows out through the outlet 11 and reaches the crossbar at the top of the pipe 5. It is then further transported to the shaft 8, piston 7, and other parts that are prone to wear and jamming, providing lubrication and maintenance for these parts, reducing friction and wear between components, and extending the service life of the valve. After maintenance, the spring 12 returns to its elasticity, pushing the long rod 9 upward to return to its initial position, ready for the next maintenance operation. Through this working principle, the high-performance eccentric hemispherical valve for mud flow obstruction can not only achieve effective mud transportation and blocking control, but also facilitate the maintenance of the internal components of the valve, ensuring the normal operation and good performance of the valve.
