Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a floating valve structure for rapid opening and closing. Background Technology

[0002] Valves are widely used in pipeline systems, but they can also malfunction and become inoperable. When pipeline leaks or other faults require emergency shut-off, current methods often involve using non-standard tools to forcibly operate or open the valve cover for repair. This approach is not only time-consuming and labor-intensive, but also prone to damaging the valve, and poses significant safety risks in flammable and explosive environments.

[0003] Based on the above reasons, this utility model designs a fast-opening floating valve structure, so that when the valve fails to operate normally, the operator can quickly and safely open or close the valve through an external interface using standard tools without opening the cover, in order to meet the emergency handling needs of the pipeline system. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fast-opening floating valve structure. When the valve malfunctions and cannot operate normally, the operator can quickly and safely open or close the valve through an external interface using standard tools without opening the cover, thus meeting the emergency handling needs of the pipeline system.

[0005] To achieve the above objectives, this utility model provides a fast-switching floating valve structure, including a valve body. A control plate is connected to the top of the valve body via a drive shaft with a central hole. The upper end of the drive shaft is connected to a motor. A support plate is connected above the motor via a bracket, and a battery is mounted on the support plate. A valve body control cover is connected to the control plate. The lower end of the drive shaft is connected to a ball core. The bottom surface of the control plate is connected to a rotating ring. The rotating ring is located on the outer periphery of the top of the valve body and above the upper plate of the valve body. The circumference of the rotating ring has an anti-rotation screw fixing hole that mates with an anti-rotation screw. The bottom surface of the rotating ring has an anti-rotation pin limiting groove that mates with an anti-rotation pin. A limiting pin that mates with the limiting pin groove on the control plate is installed on the drive shaft. A signal rod connected to the drive shaft via a signal rod fastening screw is provided on the drive shaft. The signal rod mates with a signal switch mounted on the control plate. The upper plate of the valve body has an anti-rotation pin hole that mates with the anti-rotation pin. An anti-rotation thread fixing hole that mates with an anti-rotation screw is provided on the anti-dislodgement groove on the top circumference of the valve body.

[0006] The anti-rotation screw is sealed with a lead seal.

[0007] The drive shaft and valve body are sealed by a drive shaft seal ring.

[0008] The control panel is equipped with cable connectors.

[0009] The support plate is equipped with a battery holder and a circuit board, and the battery holder is connected to the battery.

[0010] The signal switches are located below the motor and are distributed on the outer circumference of the drive shaft.

[0011] A sealing joint is provided on one side of the ball core inside the valve body. A sealing ring is provided between the inner side of the sealing joint and the ball core. The sealing ring is in contact with the pressure plate and the pressure plate gasket on the inner side of the pressure plate. The sealing ring and the pressure plate gasket are simultaneously pressed against the ball core.

[0012] The other side of the ball core is in contact with the adjusting shim, the adjusting shim is connected to the spring, the spring is connected to the adjusting connector, and the adjusting connector is connected to the valve body.

[0013] Compared with the prior art, this utility model provides an anti-rotation threaded fixing hole that mates with the anti-rotation screw on the anti-dislodgement groove at the top of the valve body. This, along with the rotating ring installed below the control plate and the anti-rotation pin limiting groove and anti-rotation screw fixing hole on it, allows the valve to be rotated directly via the control plate in case of valve failure by quickly removing the anti-rotation screw. This, in turn, drives the ball core below to rotate via the transmission shaft, enabling the valve to open and close quickly and effectively. This avoids the damage caused by the rough operation of the valve in traditional methods, as well as the dangers of forced knocking or twisting in flammable and explosive environments.

[0030] Working principle: See Figures 1-6 This utility model requires minimal debugging; specifically, as shown below... Figure 1 , Figure 4 As shown, a sealing joint 9 is installed on the valve body 15; a sealing ring 8 is installed on the sealing joint 9, and the sealing ring 8 is fixed by the pressure plate 7 and is in contact with the pressure plate gasket 6. The pressure plate 7 and the sealing ring 8 are in close contact with the ball core 5. The other side of the ball core 5 is in contact with the adjusting shim 4. The adjusting shim 4 is squeezed by the spring 3. The other end of the spring 3 is in contact with the adjusting joint 2. The adjusting joint 2 is connected to the valve body 15.

[0031] like Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the rotating ring 13 is provided with anti-rotation screw fixing hole 131 and anti-rotation pin limiting groove 132. The anti-rotation pin limiting groove 132 is a 1 / 4 semi-circular groove to limit the rotation of the anti-rotation pin 11. The number of anti-rotation screws 12 shall not be less than 4. Half of the anti-rotation screws 12 are engaged with the anti-rotation screw fixing hole 131, and the other half of the anti-rotation screws 12 are engaged with the anti-dislodgement groove 153. A lead seal 21 is also provided at the anti-rotation screw 12.

[0032] like Figure 1 , Figure 2 , Figure 3As shown, the rotating ring 13 is connected to the bottom of the control board 14. The control board 14 is equipped with signal switches 23. There are at least two signal switches 23 located at the lower end of the motor 1. The signal switches 23 cooperate with the signal rod 24. The signal rod 24 is connected to the transmission shaft 10 and fixed by the signal rod fastening screw 25. At the same time, the transmission shaft 10 is equipped with a limit pin 20. The limit pin 20 cooperates with the limit pin groove 141 on the control board 14. The limit pin groove 141 is a 1 / 4 semi-circular groove that limits the rotation of the limit pin 20. Meanwhile, the drive shaft 10 is sealed to the valve body 15 by the drive shaft sealing ring 101. The lower end is connected to the ball core 5 and the upper end is connected to the motor 1.

Maintenance personnel only need to remove the anti-rotation screw 12 that mates with the anti-rotation screw fixing hole 131, and then rotate the valve body control cover 17 to force open or close the valve. Simultaneously, to ensure that the valve is not fully opened or closed during forced opening or closing, an anti-rotation pin limiting groove 132 is provided on the rotating ring 13. During the forced opening process, when the valve is fully open or fully closed, the anti-rotation pin limiting groove 132 will limit the valve's movement.
