Description

Technical Field

[0001] The present invention relates to the technical field of offshore oil exploitation, and more particularly to a corrosion-resistant pipeline valve for offshore oil exploitation. Background Art

[0002] Offshore oil exploitation usually occurs in deep sea or coastal areas where the environmental conditions are extremely special, posing extremely high requirements on pipeline valves. The various chemical substances contained in the corrosive oil itself will react with the valve materials under specific conditions, which will cause corrosion to the valve materials, thus affecting the performance and service life of the valves. During the process of oil exploitation, precise control of fluids is also required, such as regulating flow rate, pressure, etc., which requires the valves to have good regulating performance and precise control ability. Moreover, the temperature at the bottom of the ocean is relatively low. During the process of oil exploitation, the temperature may reach the freezing point of the oil, resulting in the solidification of the oil, blocking the valve, and thus the oil cannot be transported, causing a significant impact on offshore oil exploitation or even a shutdown.

[0003] The corrosion-resistant pipeline valve for offshore oil exploitation generally consists of components such as a valve body, a valve cover, a valve seat, a valve flap (or a sphere, a gate plate, etc.). When an operator needs to open or close the valve, the valve flap (or the sphere, the gate plate, etc.) is operated to open or close the valve. When the staff encounters the situation that the sealing performance of the offshore oil exploitation valve is not good due to the accumulation of oil deposits, the valve needs to be recovered and cleaned.

[0004] Currently, when the commonly used corrosion-resistant pipeline valve for offshore oil exploitation opens or closes the valve, only this one action is performed, and the same is true for other actions. The actions of removing the oil deposits that cause poor sealing performance cannot be combined. In this way, each action requires a power source, and the internal space of the offshore oil exploitation valve will be greatly occupied, which will also affect the transportation of oil. In addition, the environment in the deep sea is extremely harsh and the temperature is extremely low. Such a temperature is likely to reach the freezing point of the oil, causing the solidification of the oil inside the valve. For this situation, the solidification of the oil needs to be solved in a timely manner to avoid the risk of the transportation pipeline bursting due to the sharp increase in the pressure inside the oil pipe caused by the blockage of the long-term transportation. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a corrosion-resistant pipeline valve for offshore oil exploitation to solve the problems existing in the above background art.

The second slider hinged to the end of the second hinged rod away from the first hinged rod moves away from the second motor under the guidance of the guiding frame.

Thus, the opening of the valve port gradually becomes larger until the valve port is completely opened. The second motor stops rotating. The shaft of the second motor starts to rotate counterclockwise. The opening of the valve port gradually becomes smaller or is completely sealed; When the second slider moves away from the second motor, the rack fixedly connected to the second slider also moves accordingly.

A screw rod 405, a side wall of the inner shell 202 is fixedly connected to one side of a heat conducting block 411, the other side of the heat conducting block 411 is fixedly connected to a heating block 410, a guide rod 406 is fixedly connected between the heating block 410 and the bottom plate 401, the first screw rod 405 is spirally connected to a first slider 407, the first slider 407 is slidably connected to the guide rod 406, a power generation block 408 is provided on one side of the first slider 407 close to the heating block 410, and at the end of the movement of the first slider 407, the power generation block 408 and the heating block 410 are in contact with each other; The valve switch assembly 5 includes a second motor 501, which is fixedly connected to the housing 2. The second motor 501 is key-connected to one end of a first hinged rod 502, the other end of the first hinged rod 502 is hinged to one end of a second hinged rod 503, the other end of the second hinged rod 503 is hinged to a second slider 504, the second slider 504 is in a 冂 shape, and a guide frame 505 is slidably connected to the outer side of the second slider 504, the guide frame 505 is in a 冂 shape, the guide frame 505 is fixedly connected to the housing 2, and the inner wall of the guide frame 505 is fixedly connected to the movable switch 6; The scrubbing assembly 8 includes a rack 801, the top of which is fixedly connected to the bottom of the second slider 504, a third gear 802 is provided below the rack 801, a central key of the third gear 802 is connected to a second screw 803, and the second screw 803 is spirally connected to a brush block 804; In this embodiment, it should be specifically explained that when the power generation block 408 contacts the heating block 410 , the heating block 410 can generate heat.

[0028] The main difference between this embodiment and the prior art is that in this embodiment, the force for moving the switch 6 is used to simultaneously address the poor sealing caused by the accumulation of petroleum deposits during the petroleum transportation process, achieving the conservation of the power source and preventing the volume generated by excessive power sources from affecting petroleum transportation. The thermometer assembly 7 senses the internal temperature and the heating assembly 4 heats the solidifying petroleum. Specifically, it includes the heating assembly 4, the valve switch assembly 5, the thermometer assembly 7, and the washing assembly 8. The above structure is the main structure of this embodiment, which solves the problem that the solidification of petroleum due to too low ocean temperature affects transportation. The first motor 402 and the second motor 501 are prior art structures, and the specific structures and connection methods of the first motor 402 and the second motor 501 are not described in detail in this embodiment.

[0029] Refer to Figure 3 , there are shock-proof components 3 arranged in a circumferential array between the outer shell 201 and the inner shell 202. The shock-proof components 3 include bump 301. One end of the bump 301 is fixedly connected to the outer wall of the inner shell 202. A shock-proof spring 302 is sleeved around the bump 301. One end of the shock-proof spring 302 is fixedly connected to the outer wall of the inner shell 202, and the other end of the shock-proof spring 302 is fixedly connected to the inner wall of the outer shell 201. The thermometer assembly 7 includes a thermometer protection box 701, and an infrared thermometer 702 is fixedly connected inside the thermometer protection box 701.

[0030] In this embodiment, it should be specifically noted that: a plurality of evenly distributed shock-proof components 3 contribute to uniformly damping the shell 2 from multiple angles when transporting petroleum in the ocean, making the mechanical mechanisms inside the shell 2 not easily shaken loose. When a strong vibration occurs in the ocean and the vibration is transmitted to the shell 2, the vibration is transmitted from the outside to the inside of the shell 2. At this time, when the vibration is transmitted to the shock-proof spring 302, the vibration transmitted to the inside of the shell 2 is reduced through the contraction and expansion of the shock-proof spring 302. The vibration is then transmitted to the inside through the bump 301, and the vibration throughout the process is reduced, protecting the stability of the mechanical structure inside the shell 2. When the freezing point of the petroleum is determined, the set temperature of the infrared thermometer 702 is adjusted to this freezing point. When the temperature drops to this temperature, the infrared thermometer 702 sends a signal to the central control system. When the petroleum temperature gradually rises and is higher than the freezing point of petroleum solidification, the infrared thermometer 702 sends a signal to the central control system.

[0031] Refer to Figures 4 - 6, an anti-corrosion coating layer 203 and a waterproof material coating layer 204 are brushed on the inner wall of the inner shell 202. A bottom circular plate 205 is fixedly connected to the bottom of the outer shell 201. A through valve port 209 is opened at the center of the bottom circular plate 205. A square groove 206 is provided on one side of the valve port 209. A circular groove 208 is provided below the valve port 209. A placement groove 207 is communicated between the circular groove 208 and the square groove 206. The square groove 206 is a guiding groove for a rack 801. A moving switch 6 is slidably and sealingly connected to the hole grooves connecting the placement groove 207 and the circular groove 208.

[0032] In this embodiment, it should be specifically noted that: the waterproof material coating layer 204 blocks and prevents the penetration of moisture in the petroleum inside the inner shell 202. The anti-corrosion coating layer 203 blocks the substances in the petroleum that are likely to corrode the inner wall of the inner shell 202 and prevents them from undergoing chemical and physical reactions with the inner wall of the inner shell 202. When it is necessary to open the valve port 209, the moving switch 6 moves towards the other end of the circular groove 208 inside the circular groove 208, gradually opening the valve port 209. The rack 801 also moves in the same direction. The rack 801 begins to gradually mesh with the third gear 802, driving the third gear 802 to rotate, driving the second screw rod 803 key-connected thereto to rotate. The second screw rod 803 drives the brush block 804 to move away from the third gear 802. When it is necessary to close the valve port 209, the moving switch 6 moves towards the end of the circular groove 208 close to the square groove 206 inside the circular groove 208, and the rack 801 also moves accordingly.

[0033] Refer to Figure 7 , the moving switch 6 includes a stop block 601. A placement groove 602 is provided at the bottom of the stop block 601. An avoidance groove 603 runs through the middle of the placement groove 602. A baffle 604 is provided on the side of the stop block 601 opposite to the placement groove 602. The baffle 604 is slidably and sealingly connected to the circular groove 208. A guiding hole 605 is opened inside the baffle 604. The guiding hole 605 is slidably connected to a guide rod 506.

[0034] In this embodiment, it should be specifically noted that: when it is necessary to open the valve port 209, the stop block 601 is pushed by the second slider 504 to move towards the other end of the circular groove 208. When it is necessary to close the valve port 209, the stop block 601 is pushed by the second slider 504 to move towards the end of the circular groove 208 close to the square groove 206. The baffle 604 moves under the guidance of the guide rod 506 in both cases.

[0035] Refer to Figure 8 , the brush block 804 is in the shape of an L-shaped plate. A number of brushing grooves 806 are provided on one side and the bottom of the brush block 804. Steel bristles 807 are provided inside the brushing grooves 806. A threaded hole 805 runs through the middle of the brush block 804. The steel bristles 807 are in contact with the vertical and bottom walls of the square groove 206.

[0036] In this embodiment, it should be specifically noted that: the second screw 803 drives the brush block 804 to move away from the third gear 802, and the steel bristles 807 brush the vertical wall and the bottom wall of the square groove 206 in contact therewith. The suspended matter washed out is discharged along with the petroleum. The brush block 804 moves towards the third gear 802, and the steel bristles 807 brush the vertical wall and the bottom wall of the square groove 206 in contact therewith again.

[0037] The working principle of the present invention: The main problem solved by this embodiment is: using the force of moving the switch 6 to simultaneously handle the poor sealing caused by the accumulation of petroleum deposits during the petroleum transportation process, realizing the saving of the power source, and not affecting the petroleum transportation due to the volume generated by excessive power sources. At the same time, using the thermometer component 7 to sense the internal temperature and using the heating component 4 to heat the solidifying petroleum to avoid the impact of petroleum solidification on transportation.

[0038] The specific steps are as follows: First, when the transported petroleum passes through the valve body main body 1 and the inside of the housing 2, according to the signal sent by the central control system, the second motor 501 is started. The shaft of the second motor 501 starts to rotate clockwise. The shaft of the second motor 501 drives the first hinge rod 502 fixedly connected thereto to rotate. One end of the first hinge rod 502 away from the second motor 501 moves away from the center of the housing 2. The first hinge rod 502 drives one end of the second hinge rod 503 hinged thereto to rotate. The second slider 504 hinged to the end of the second hinge rod 503 away from the first hinge rod 502 moves away from the second motor 501 under the guidance of the guide frame 505. The moving switch 6 fixedly connected to the second slider 504 also moves away from the second motor 501 under the guidance of the guide rod 506. Thus, the opening of the valve port 209 gradually becomes larger until the stop block 601 abuts against the guide frame 505 and the valve port 209 is completely opened. At this time, the area of the valve port 209 reaches the maximum, and the second motor 501 stops rotating; When it is necessary to adjust the transportation flow rate of petroleum or close the valve, the central control system sends a signal. The shaft of the second motor 501 starts to rotate counterclockwise. The shaft of the second motor 501 drives the first hinge rod 502 fixedly connected thereto to rotate. One end of the first hinge rod 502 away from the second motor 501 moves towards the center of the housing 2. The first hinge rod 502 drives one end of the second hinge rod 503 hinged thereto to rotate. The second slider 504 hinged to the end of the second hinge rod 503 away from the first hinge rod 502 moves towards the second motor 501 under the guidance of the guide frame 505. The moving switch 6 fixedly connected to the second slider 504 also moves towards the second motor 501 under the guidance of the guide rod 506. Thus, the opening of the valve port 209 gradually becomes smaller or is completely sealed; When the second slider 504 moves away from the second motor 501, the rack 801 fixedly connected to the second slider 504 also moves accordingly. The rack 801 begins to gradually engage with the third gear 802, driving the third gear 802 to rotate, driving the second screw rod 803 key-connected thereto to rotate. The second screw rod 803 drives the brush block 804 to move away from the third gear 802. The brush block 804 scrubs the vertical wall and the bottom wall of the placement groove 207 in contact therewith. The suspended matter washed out is discharged along with the petroleum, avoiding the failure of the sealing of the valve port 209 due to the blockage of petroleum deposits when the movement switch 6 is closed. Similarly, when the second slider 504 moves towards the second motor 501, the brush block 804 moves towards the third gear 802, and the brush block 804 scrubs the vertical wall and the bottom wall of the placement groove 207 in contact therewith again; When the freezing point of the petroleum for this time is determined, the set temperature of the thermometer assembly 7 is adjusted to this freezing point. When the temperature drops to this temperature, the infrared thermometer 702 senses and sends a signal to the central control system. The central control system will control the first motor 402 to start. The first motor 402 drives the first gear 403 key-connected thereto to rotate. The first gear 403 drives the second gear 404 engaged therewith to rotate. The second gear 404 drives the first screw rod 405 key-connected thereto to rotate. The first screw rod 405 drives the first slider 407 connected thereto by screw drive to move towards the heating block 410 under the guidance of the guide rod 406. The energized power generation block 408 also moves and gradually connects with the heating block 410. After the power generation block 408 is connected to the heating block 410, the heating block 410 is energized to generate heat, and the heat conducting block 411 also begins to conduct the heat of the heating block 410. The heat conducting block 411 heats the petroleum in the process of solidification or already solidified, causing the temperature of the petroleum to rise and avoiding solidification. When the temperature of the petroleum gradually rises and is higher than the freezing point of the petroleum solidification, the infrared thermometer 702 senses the temperature and sends a signal to the central control system. The system will control the first motor 402 to reverse, and the power generation block 408 and the heating block 410 are separated, and the heating block 410 loses heat; When a strong vibration occurs in the ocean and the vibration is transmitted to the housing 2, the vibration is transmitted from the outside to the inside of the housing 2. At this time, when the vibration is transmitted to the shock-proof spring 302, the vibration transmitted to the inside of the housing 2 is reduced through the contraction and expansion of the shock-proof spring 302. The vibration is then transmitted to the inside through the convex block 301, and the vibration in the whole process is reduced, protecting the stability of the mechanical structure inside the housing 2.

[0039] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
