Description

Technical Field

[0001] This utility model belongs to the field of power station valves, and specifically relates to a self-sealing power station valve. Background Technology

[0002] Power station valves are valves specifically designed for use in power systems. They are typically used in power plants, substations, and other electrical equipment to control the flow, pressure, and temperature of fluids. Power station valves play a crucial role, especially in high-pressure and high-temperature operating environments, where they ensure the safe and efficient operation of the power system.

[0003] Most existing power station valves are controlled by a single electric or manual opening and closing mechanism. However, electric opening and closing mechanisms are prone to failure in actual use, while manual opening and closing mechanisms are time-consuming and labor-intensive due to manual rotation. This results in poor convenience and safety when using power station valves. Furthermore, the hydraulic pressure inside the power station valve usually maintains a stable value when there is no leakage. However, when the power station valve leaks, the unstable hydraulic pressure will cause the fluid to leak out rapidly from the leak point, which may lead to damage to the power station valve.

[0004] Therefore, to address the problem that existing power station valves are difficult to automatically close when leaks occur, and that their switching structure is difficult to continue controlling the opening and closing of the power station valve after a failure, a self-sealing power station valve is developed. By adding a hydraulic detection structure, an electric switching structure, and a manual switching structure to the power station valve, the valve can be effectively closed when a leak occurs, and the manual structure can control the opening and closing of the power station valve after the electric switching structure fails. Utility Model Content

[0005] To overcome the problem that existing power plant valves are difficult to automatically close when leakage occurs, and that their switching structure is difficult to continue controlling the opening and closing of the power plant valve after a failure.

[0006] The technical solution of this utility model is as follows: a self-sealing power station valve, including a valve body connector and a power station valve body, and also including a ball valve, a servo motor, a handle, a hydraulic sensor and a connecting rod. The valve body connector is fixed to both ends of the power station valve body. The ball valve is installed on the inner wall of the power station valve body. The upper end of the ball valve is fixed to the connecting rod. The upper end of the connecting rod is fixed to the handle. The output end of the servo motor is fixed to the upper end of the handle. A first groove is opened at the upper end of the power station valve body. A sealing mounting plate is installed on the inner wall of the first groove by fixing bolts. The upper and lower edges of the sealing mounting plate are provided with mounting grooves. A hydraulic sensor is installed in the mounting groove. A support cylinder is installed at the center of the upper end of the sealing mounting plate. The upper outer wall of the connecting rod is provided with external threads. The lower outer wall of the connecting rod is fitted with a sealing sleeve. A threaded sleeve is installed through the inner wall of the support cylinder.

[0007] Preferably, the sealing mounting plate has a first through hole through the center of both the upper and lower ends, and the first through hole corresponds to the threaded sleeve.

[0008] Preferably, the motor frame is U-shaped, with a second connecting slot and a first connecting slot respectively through the upper and lower ends of the motor frame.

[0009] Preferably, the upper end of the servo motor is fixedly connected to the second connecting groove, and the first connecting groove is fixedly connected to the upper outer wall of the support frame.

[0010] Preferably, the external thread is threaded to the threaded sleeve, and the sealing sleeve is rotatably installed in the first through hole.

[0011] Preferably, the hydraulic sensor is electrically connected to the servo motor, and the handle is located on the inner wall of the motor frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. The pressure of the fluid in the power station valve body is detected in real time by a hydraulic sensor. When a leak occurs in the power station valve body, the servo motor is started to drive the connecting rod to rotate, thereby driving the ball valve to rotate and close on the inner wall of the power station valve body to prevent further leakage of the transported fluid.

[0014] 2. The ball valve can be manually operated by turning the handle connected to the connecting rod to open or close when the servo motor fails, thus achieving dual guarantee for the opening and closing of the power station valve body. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a self-sealing power station valve, including a valve body connector 1 and a power station valve body 2, and further including a ball valve 14, a servo motor 6, a handle 18, a hydraulic sensor 19, and a connecting rod 16. The valve body connector 1 is fixedly connected to both the front and rear ends of the power station valve body 2. The ball valve 14 is installed on the inner wall of the power station valve body 2. The connecting rod 16 is fixedly connected to the upper end of the ball valve 14, and the handle 18 is fixedly connected to the upper end of the connecting rod 16. The output end of the servo motor 6 is fixedly connected to the upper end of the handle 18. The upper end of the power station valve body 2 is provided with a first groove 7. The inner wall of the first groove 7 is fitted with a sealing mounting plate 3 by fixing bolts 8. The upper and lower edges of the sealing mounting plate 3 are provided with mounting grooves 10. A hydraulic sensor 19 is installed in the mounting grooves 10. A support cylinder 5 is installed at the upper center of the sealing mounting plate 3. The upper outer wall of the connecting rod 16 is provided with external threads 17. The lower outer wall of the connecting rod 16 is fitted with a sealing sleeve 15. A threaded sleeve 11 is installed through the inner wall of the support cylinder 5.

[0023] The hydraulic sensor 19 can detect the pressure of the fluid in the power station valve body 2 in real time. When leakage occurs in the power station valve body 2 and valve body joint 1, abnormal hydraulic data is sent to the servo motor 6, which then drives the connecting rod 16 to rotate. This drives the ball valve 14 to rotate and close on the inner wall of the power station valve body 2, thus preventing further leakage of the external fluid. In the event of a malfunction of the servo motor 6, the handle 18 connected to the connecting rod 16 can be manually operated to drive the ball valve 14 to rotate and open or close, thus providing a dual guarantee for the opening and closing of the power station valve body 2.

[0024] Please see Figures 3-5In this embodiment, the upper and lower ends of the sealing mounting plate 3 are provided with a first through hole 9, which corresponds one-to-one with the threaded sleeve 11. In use, the one-to-one correspondence of the first through hole 9 and the threaded sleeve 11 can keep the connecting rod 16 and the external thread 17 in a straight line, so as to ensure that the servo motor 6 and the special handle 18 can drive the ball valve 14 to rotate and open. The motor frame 4 is U-shaped, and the upper and lower ends of the motor frame 4 are respectively provided with a second connecting groove 13 and a first connecting groove 12. In use, the U-shaped motor frame 4 can support the servo motor 6 and ensure that the servo motor 6 is located at the upper end of the handle 18. The upper end of the servo motor 6 is fixed in the second connecting groove 13, and the first connecting groove 12 is fixed to the upper outer wall of the support cylinder frame 5. In use, the support cylinder frame 5 can cover and protect the connecting rod 16, thereby avoiding damage from collisions with foreign objects.

[0025] Please see Figures 4-5 In this embodiment, the external thread 17 is threadedly connected to the threaded sleeve 11, and the sealing sleeve 15 is rotatably installed in the first through hole 9. In use, the sealing sleeve 15 can fill the gap between the first through hole 9 and the connecting rod 16 to further maintain the airtightness between the connecting rod 16 and the first through hole 9. The hydraulic sensor 19 is electrically connected to the servo motor 6, and the handle 18 is located on the inner wall of the motor frame 4. In use, the hydraulic sensor 19 can detect the fluid hydraulic pressure in the power station valve body 2 in real time.

[0026] During use, the hydraulic pressure in the fluid inside the power station valve body 2 is detected in real time by the hydraulic sensor 19. When the power station valve body 2 leaks, the hydraulic pressure in the fluid inside it will drop. Based on the information of the hydraulic pressure change, the hydraulic sensor 19 starts the servo motor 6. The servo motor 6 drives the connecting rod 16 to rotate along the inner wall of the threaded sleeve 11, thereby driving the ball valve 14 to rotate and close on the inner wall of the power station valve body 2 to prevent further leakage of the transported fluid.

[0027] When the servo motor 6 malfunctions, the handle 18 is manually turned to drive the handle 18 connected to the connecting rod 16, thereby causing the ball valve 14 to rotate to open or close, thus achieving a dual guarantee for the opening and closing of the power station valve body 2.

[0028] Through the above steps, the pressure of the fluid in the power station valve body 2 is detected in real time by the hydraulic sensor 19. When a leak occurs in the power station valve body 2, the servo motor 6 is started to drive the connecting rod 16 to rotate, thereby driving the ball valve 14 to rotate and close on the inner wall of the power station valve body 2 to prevent further leakage of the transported fluid. When the servo motor 6 fails, the handle 18 connected to the connecting rod 16 can be manually turned to drive the ball valve 14 to rotate open or close, thus achieving dual guarantee for the opening and closing of the power station valve body 2. This solves the problem that existing power station valves are difficult to automatically close when a leak occurs, and that their switching structure is difficult to continue controlling the opening and closing of the power station valve after a failure.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
