[0002] With the development of the offshore oil and gas extraction industry, the number of oil and gas extraction platforms has increased rapidly. In the process of deepwater oil and gas field extraction, in order to ensure the personal safety of frontline workers, whenever a typhoon comes, the oil and gas extraction platform will evacuate the frontline workers in advance and switch to remote-controlled typhoon mode production. In this mode, if the shutdown is triggered by a jump in the instrument signal, it is impossible to remotely reset the emergency shutdown / relief valve to resume production, which will seriously affect downstream users.

[0003] As the times continue to progress, the application of intelligence and digitalization in the offshore oil and gas extraction industry will become more and more common. After the existing emergency shut-off / release valves are shut off, personnel are required to reset the emergency shut-off / release valves on site, which will inevitably hinder the advancement of intelligence in the offshore oil and gas extraction industry, and the construction progress of unmanned platforms will also be affected.

[0004] In order to accelerate the construction of intelligent and digital oil and gas production in China's offshore areas, further promote the development of unmanned platforms, and solve the bottleneck problem of unmanned platform production, it is becoming more and more urgent. As a key equipment in the safety system of the oil and gas production industry, it is particularly important to realize the remote reset of emergency shut-off / release valves.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0026] Figure 1 is a schematic diagram of the structure of a remote reset system for an emergency shut-off / relief valve in some embodiments of the present invention;

[0027] Figure 2 yes Figure 1 A schematic diagram of the structure of a reset button for a remote reset system of an emergency shut-off / relief valve is shown. DETAILED DESCRIPTION

[0028] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0029] Figure 1 Some preferred embodiments of the remote reset system for emergency shut-off / relief valves of the present invention are shown. The remote reset system for emergency shut-off / relief valves can remotely reset the emergency shut-off / relief valves, and uses an external power source to achieve remote resetting of the valves, eliminating the link of personnel resetting the valves on site, and realizing intelligent production resumption after shutting down. In some embodiments, the emergency shut-off / relief valve is a ball valve driven by an air source that is widely used in the prior art and is used to cut off a process or release pressure. Specifically, in some embodiments, the emergency shut-off / relief valve includes an emergency shut-off valve (SDV) and an emergency relief valve (BDV).

[0030] like Figure 1 As shown, the remote reset system shell for the emergency shut-off / release valve includes an air source drive assembly 10 and a reset device 20; the air source drive assembly 10 can be connected to the reset device 20, and can be used to drive the reset device 20 to reset the emergency shut-off / release valve. The reset device 20, the air source drive assembly 10 and the emergency shut-off / release valve can reset the emergency shut-off / release valve under the drive of the air source, thereby realizing the intelligent resumption of production after shutdown, thereby saving labor costs.

[0031] Further, in some embodiments, the gas source drive assembly 10 may include a gas source storage device 11 and a gas source delivery pipeline 12. The gas source storage device 11 can be used to store a gas source, which can be air or an inert gas. In some embodiments, the gas source storage device 11 can be a gas source storage tank. One end of the bottom edge delivery pipeline 12 can be connected to the gas source storage device 11, and the other end can be connected to the reset device 20, which can be used to output the gas source in the gas source storage device 11 to the reset device 20, so as to drive the reset device 20 to drive the emergency shut-off / relief valve to reset. It can be understood that in some other embodiments, the gas source drive assembly 10 may also include a booster pump, which can be arranged on the gas source delivery pipeline 12, and can be used to pressurize the reset device 20.

[0032] Further, in some embodiments, the emergency shut-off / release valve may be multiple, and the corresponding reset device 20 may also be multiple. The gas source delivery pipeline 12 may include a main pipe 121 and multiple branch pipes 122. One end of the main pipe 121 may be connected to the gas source storage device 11, and the multiple branch pipes 122 may be connected to the main pipe 121, and each branch pipe 122 may be arranged corresponding to a reset device 20. In some embodiments, an interface may be reserved on the main pipe 121 to prepare for the access of new equipment. In some embodiments, a threaded connector 123 may be arranged at one end of the gas source delivery pipeline 12; specifically, in some embodiments, the threaded connector 123 may be multiple, and it is arranged corresponding to each branch pipe 122, and it is arranged at one end of the branch pipe 122 away from the main pipe 121. The threaded connector 123 can be used to connect to the reset device 20. In some embodiments, a joint 124 may also be arranged on the gas source delivery pipeline 12. The joint 124 can be disposed between the gas source delivery pipeline 12 and the threaded connector 123, and can be used to connect the gas source delivery pipeline 12 and the threaded connector 123. Specifically, there can be multiple joints 124, which can be disposed one by one corresponding to the branch pipe 122 to connect the corresponding branch pipe 122 and the threaded connector 123.

[0033] Further, in some embodiments, a remote switch valve 13 may be provided on each branch pipe 122. When the remote switch valve 13 is opened, the gas in the branch pipe 122 can be transported to the reset device 20, and when the remote switch valve 13 is closed, the gas in the branch pipe 122 can stop being transported to the reset device 20. In some embodiments, the remote switch valve 13 may be a remote control ball valve with two variables of open and close, which can be opened or closed by remote control. It can be understood that in some other embodiments, the remote switch valve 13 is not limited to being provided on the branch pipe 122, and it can also be provided on the main pipe 121.

[0034] Furthermore, in some embodiments, a time delay valve 14 may be provided on each branch pipe 122. The opening time of the time delay valve 14 may be adjusted, and may be opened according to a time point. By providing a time delay valve 14 on each branch pipe 122, different opening times may be set for the time delay valve 14 on each branch pipe 122, so that the time of gas path conduction of different branch pipes 122 may be different, and the order of resetting different valves in the same system may be adjusted by adjusting the time setting point. It is understandable that in some other embodiments, a stop valve or a needle valve may be used instead of the time delay valve 14.

[0035] Furthermore, in some embodiments, a pressure regulating valve 15 may be provided on the main pipe 121 . The pressure regulating valve 15 may regulate the gas pressure in the main pipe 121 and distribute the depressurized gas in the gas source storage device 11 to each branch pipe 122 .

[0036] Furthermore, in some embodiments, a pressure transmitter 16 may be provided on the main pipe 121. The pressure transmitter 16 can be used to monitor the gas pressure in the main pipe 121 in real time, and cooperates with the pressure regulating valve 15 to adjust the gas pressure output by the main pipe 121.

[0037] like Figure 1 and Figure 2 As shown, further, in some embodiments, the reset device 20 may include a guide cylinder 21 and a reset button 22. The guide cylinder 21 may be a hollow columnar structure with two ends connected, and may include a first end and a second end, wherein the first end may be connected to the gas source delivery pipeline 12, and the second end may be used for connecting the reset button 22 to the emergency shut-off / release valve. The reset button 22 may be arranged in the guide cylinder 21, one end of which is connected to the emergency shut-off / release valve, and it may reciprocate between the first end and the second end of the guide cylinder 21 under the drive of the gas source, thereby resetting the emergency shut-off / release valve.

[0038] Further, in some embodiments, the first end of the guide cylinder 21 may be provided with a threaded interface 211, and the threaded interface 211 may be connected to the threaded connector 123. Specifically, the inner side wall of the threaded interface 211 is provided with an internal thread, and the outer side wall of the threaded connector 123 is provided with an external thread. The threaded connector 123 can be inserted from the first end of the guide cylinder 21 and connected to the guide cylinder 21 through the cooperation of the internal thread and the external thread, thereby facilitating the disassembly, replacement and maintenance of the reset button. In some embodiments, an air outlet 212 may be provided on the side wall of the guide cylinder 21, and the air outlet 212 may be used to discharge the gas in the guide cylinder 21, which can ensure that the gas source delivery pipeline 12 can operate normally when the reset system is turned on, and can also slowly release the pressure in the gas source delivery pipeline 12 after the reset is completed to reset the reset button 22. The air outlet 212 may be provided with a plug body that blocks the air outlet 212 when the gas source is delivered to prevent gas from escaping. The plug body can be detachably connected to the air outlet 212 , and the plug body can be detached from the air outlet 212 to make the air outlet 212 conductive.

[0039] Further, in some embodiments, the reset button 22 may include a sliding portion 221 and a touch portion 222. The sliding portion 221 may be cylindrical, and may be in close contact with the inner side wall of the guide cylinder 21, so that the interval between the sliding portion 221 and the threaded connector 12 may form a closed space, which may be used for gas injection to generate power, so that the sliding portion 221 may reciprocate between the first end and the second end of the guide cylinder 21 under the drive of the gas source. In some embodiments, one end of the touch portion 222 may be connected to the emergency shut-off / release valve, and the other end may be connected to the sliding portion 221. The touch portion 222 may be hollow cylindrical, and its radial dimension may be smaller than that of the sliding portion 221. The touch portion 222 may be integrally formed with the sliding portion 221, and the touch portion 222 may be driven by the sliding portion 221 to touch the emergency shut-off / release valve, so that the emergency shut-off / release valve is reset. In some embodiments, the reset button 22 further includes an elastic member 223, which can be disposed in the touch portion 222, one end of which can abut against the sliding portion 221, and the other end of which can be connected to the emergency shut-off / release valve, and can generate elastic force to drive the sliding portion 221 to reset. In some embodiments, the elastic member 223 can be a spring.

[0040] When the remote reset system for the emergency shut-off / release valve is operated, when the emergency shut-off / release valve is triggered to shut down, after confirming that the site is safe and controllable, the remote control valve 13 and the pressure regulating valve 15 on the corresponding branch pipe 122 are opened. After the gas source is turned on, the gas source pressure acts as a power source to drive the sliding part 221 of the reset button 22 to move from the first end to the second end of the guide cylinder 221 to drive the emergency shut-off / release valve to reset. Then close the remote control valve 13, turn on the air outlet 212, so that the gas pressure in the gas source delivery pipeline 12 is slowly released, and after the pressure is reduced, the reset button returns to its position. By adopting the reset system of the present invention, remote operation and reset of the emergency shut-off / release valve after shutting down can be realized under remote operation conditions (such as typhoon mode production of offshore oil and gas production), so as to ensure normal production of the system.

[0041] It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the coverage of the claims of the present invention.
