[0002] Reset type electric fire protection valves are a specific type of fire safety equipment, mainly used in the fire protection system of buildings or other facilities. Their main function is to automatically close the valve when a fire occurs to prevent the spread of fire or control the spread of fire, while allowing the fire extinguishing system to effectively extinguish the fire. Overall, reset type electric fire protection valves play a key role in protecting the safety of buildings and personnel. They are an important part of modern fire protection systems, helping to prevent the spread of fire, reduce property losses, and provide a higher level of fire safety performance.

[0003] The current reset-type electric fire-fighting valve usually needs to open the fire valve and release the locking structure when it is manually reset. This makes the subsequent reset operation cumbersome and affects work efficiency.

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] Please refer to Figure 1-5 A reset type electric fireproof valve comprises a valve body 1, both ends of the valve body 1 are fixedly connected with threaded connectors 2, the center of the valve body 1 is fixedly connected with two alternately arranged limit blocks 3, the center of the valve body 1 is rotatably connected with a rotating shaft 4, and the outer wall of the rotating shaft 4 is fixedly connected with a valve core 5; the top of the outer wall of the rotating shaft 4 is fixedly connected with a first gear 6, the top of the valve body 1 is fixedly connected with a mounting frame 7, the mounting frame 7 is rotatably connected with a mounting shaft 8, the outer wall of the mounting shaft 8 is fixedly connected with a second gear 9 meshing with the first gear 6, the top of the mounting frame 7 is fixedly connected with a driving motor 10, the output shaft of the driving motor 10 is connected to one end of the mounting shaft 8, a reset self-locking component 11 is arranged on the top of the valve body 1, and a smoke sensor 12 is arranged on the reset self-locking component 11.

[0025] The outer diameter of the valve core 5 is the same as the inner diameter of the valve body 1, so that the valve core 5 can have a high sealing performance with the valve body 1 after closing, thereby preventing the flow of water or fire extinguishing agent, so that the fire extinguishing resources are concentrated on the fire location to prevent the fire from spreading or control the spread of the fire.

[0026] The distance between the two limit blocks 3 is the same as the thickness of the valve core 5, so that when the valve core 5 rotates in a certain direction, it can fit tightly between the two limit blocks 3, and sealing can be achieved at this time, which has a good limiting effect on the valve core 5 and enables it to have a better closed sealing state.

[0027] Axial holes are provided on the valve body 1 and the mounting frame 7, and the rotating shaft 4 and the mounting shaft 8 both pass through the centers of the corresponding axial holes; so that the rotating shaft 4 and the mounting shaft 8 can both rotate at the centers of the corresponding axial holes, and then the mounting shaft 8 is driven by the driving motor 10 to rotate, and then the rotating shaft 4 is driven to rotate through linkage control, thereby completing the adjustment of the valve core 5.

[0028] The reset self-locking component 11 includes a protective frame 1101 fixedly connected to the top of the outer wall of the valve body 1, a slider 1102 is slidably connected to one side of the protective frame 1101, a first fixed block 1103 is fixedly connected to one side of the front and rear ends of the slider 1102, two first fixed blocks 1103 are fixedly connected to springs 1104, the other ends of the two springs 1104 are connected to the inner wall of the protective frame 1101, the other sides of the front and rear ends of the slider 1102 are fixedly connected to second fixed blocks 1105, the two second fixed blocks 1105 are fixedly connected to electric rods 1106, and the fixed ends of the two electric rods 1106 are connected to the protective frame 1101. The outer wall is connected, and a pulling hole 1107 is provided at one end of the slider 1102; when the driving motor 10 completes its work, the power is cut off to the fire area, and the electric rod 1106 after the power is cut off no longer has the thrust to the slider 1102, and due to the rebound force of the spring 1104, the first fixed block 1103 drives the slider 1102 to reset, so that it meshes with the first gear 6, completing the self-locking, so that the valve core 5 can no longer rotate, and during subsequent manual reset, the slider 1102 is pulled to move through the pulling hole 1107, and then the channel is opened by rotating the valve core 5, and after power is supplied, the slider 1102 can be pushed to move by the electric rod 1106 to release the self-locking.

[0029] A guide hole corresponding to the slider 1102 is provided on the protective frame 1101, and the slider 1102 passes through the center of the guide hole; the slider 1102 can slide on the protective frame 1101, and then the first gear 6 is locked and unlocked by sliding back and forth, which has high portability.

[0030] A toothed plate corresponding to the first gear 6 is installed at the other end of the slider 1102; when the slider 1102 moves to the position of the first gear 6, the toothed plate can mesh with the first gear 6, thereby limiting the rotation of the first gear 6 and preventing the valve core 5 from rotating.

[0031] The working principle of the utility model is: when a fire occurs, the smoke sensor 12 can detect the generation of smoke, and the drive motor 10 is started, driving the installation shaft 8 to rotate, and then driving the second gear 9 to rotate, and the first gear 6 engaged therewith rotates accordingly, driving the rotating shaft 4 to rotate, and the valve core 5 rotates accordingly, and fits tightly with the two limit blocks 3, so as to achieve fire sealing, block the flow of water and fire extinguishing agent, and concentrate resources for fire extinguishing. When the drive motor 10 completes its work, the fire area is powered off. After the power is off, the electric rod 1106 no longer has the thrust on the slider 1102. Due to the rebound force of the spring 1104, the first fixed block 1103 drives the slider 1102 to reset, so that it meshes with the first gear 6, completes the self-locking, and prevents the valve core 5 from rotating again. When manually resetting later, the slider 1102 is pulled to move through the pulling hole 1107, and then the channel is opened by rotating the valve core 5. After power is supplied, the slider 1102 can be pushed to move by the electric rod 1106 to release the self-locking.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
