[0020] In order to thoroughly understand the present invention, a detailed structure will be presented in the following description to illustrate the technical solution proposed by the present invention. The optional embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0021] Please refer to the attached Figure 1 The present application provides an oil and gas recovery unloading valve, including a valve body 1, a sector tooth 2 and a valve disc 3. A guide column 4 is arranged in the valve body 1. The guide column 4 is connected to the inner wall of the valve body 1 through a plurality of ribs (not shown) in the circumferential direction. An adjusting rod 5 is slidably arranged in the guide column 4. The lower end of the adjusting rod 5 is connected to the valve disc 3. A tooth groove 6 is arranged on the adjusting rod 5. The sector tooth 2 is meshed with the tooth groove 6. The adjusting component drives the sector tooth 2 to rotate. The adjusting component includes a first rotating rod 9, a first gear 10, a second gear 11, a secondary bevel gear 14, and a second rotating rod 12. And a rotating part 15, the sector teeth 2 and the first gear 10 are both sleeved on the first rotating rod 9, the second gear 11 and the slave bevel gear 14 are both sleeved on the second rotating rod 12, one end of the first rotating rod 9 and the second rotating rod 12 are respectively rotatably connected to the rib plate, the first gear 10 is meshed with the second gear 11, the rotating part 15 is arranged on the valve body 1 and is rotatably connected with the valve body 1, a main bevel gear 13 is provided below the rotating part 15, and the main bevel gear 13 is meshed with the slave bevel gear 14.

[0022] The oil and gas recovery and unloading valve provided in the present application drives the main bevel gear 13 to rotate through the rotating part 15 when in use, and the main bevel gear 13 drives the slave bevel gear 14 to rotate, and then the slave bevel gear 14 drives the second rotating rod 12 to rotate, the second rotating rod 12 drives the second gear 11 to rotate, the second gear 11 drives the first gear 10 to rotate, and the first gear 10 drives the first rotating rod 9 to rotate, and finally the first rotating rod 9 drives the fan-shaped teeth 2 to rotate, and the fan-shaped teeth 2 and the tooth grooves 6 cooperate with each other to drive the adjusting rod 5 to move upward, thereby driving the valve disc 3 to move upward to open the valve. It should be noted that in the embodiment provided in the present application, the second gear 11 is smaller than the first gear 10, which causes the rotation speed of the second rotating rod 12 to be greater than the first rotating rod 9, so that the user can make the gear transmission rack with only a small force. Therefore, the present application reduces the opening torque through the adjusting component, which is more time-saving and labor-saving, and easy to use.

[0023] In an embodiment provided in the present application, a magnet (not marked) is embedded on the rotating part 15, and a Hall sensor (not marked) is provided on the valve body 1 outside the magnet. Specifically, when the rotating part 15 rotates, the position change of the magnet on the rotating part 15 and the Hall sensor generates a position output signal. The number of rotations can be known through the above signal, which facilitates the user to achieve precise control of the opening degree of the valve flap 3.

[0024] In one embodiment provided in the present application, the signal output end of the Hall sensor is connected to the Bluetooth module signal, and the Bluetooth module is connected to the signal of a device such as a handheld terminal. The signal is transmitted through the Bluetooth module, and the signal is analyzed by the handheld terminal to obtain the number of circles. It can be understood that the method of obtaining the number of circles through the position output signal is a conventional technical means in the field, and the present application will not elaborate on it here.

[0025] Specifically, the rotating part 15 is a hand valve, and the user rotates the hand valve manually to drive the main bevel gear 13 to rotate.

[0026] Specifically, the rotating part 15 is a torque bolt, which is rotated by an electric wrench with Bluetooth function. The function of its Bluetooth function is to receive the position output signal of the Bluetooth module and generate the number of turns. Only the number of turns needs to be input, and the electric wrench can drive the torque bolt to rotate the rated number of turns under the drive of electricity.

[0027] Specifically, an upper cover 17 is disposed at the bottom end of the valve body 1 , an opening 18 is disposed at the center of the upper cover 17 , and an end cover 19 is disposed at the bottom end of the valve flap 3 , and the end cover 19 is in contact with the upper cover 17 .

[0028] Specifically, a spring 16 is sleeved on the valve flap 3, and one end of the spring 16 is connected to the top of the end cover 19. The spring 16 is sleeved on the valve flap 3, and the spring 16 is a compression spring. When the staff drives the sector tooth 2 to rotate upward to drive the valve flap 3 to rise, the end cover 19 connected to the bottom end of the valve flap 3 rises at the same time, and the spring 16 is squeezed by the end cover 19. When the staff rotates the sector tooth 2 in the opposite direction, the spring 16 can push the contacted end cover 19 to fall quickly to ensure the closing speed of the device. At the same time, when the end cover 19 and the upper cover 17 are closed, in order to ensure that the end cover 19 will not move at will during the driving of the tanker, the spring 16 remains in a compressed state, and the driving force generated by the compression of the spring 16 ensures that the end cover 19 and the upper cover 17 continue to fit, thereby ensuring the airtightness of the device.

[0029] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
