Multi-pass, independently controlled offshore platform dispatching multi-way valve device

Abstract

This application discloses a multi-channel independently controlled multi-way valve device for marine platform scheduling. An inner connector is slidably disposed within a transverse channel and partially extends out of the channel. A sliding rod passes through the inner cover and connects to the inner connector. The inner connector and the front end of the transverse channel clamp a second elastic element. When the transverse channel aligns with a pair of side connectors, a push rod extends from the outer end of the sliding rod, thereby connecting the inner connector to the joint cup and providing access to the side connectors. The first elastic element of the multi-channel independently controlled multi-way valve device for marine platform scheduling provided by this invention provides sealing and reset force between the joint cup and the joint groove. The connector is slidably disposed within a stopcock. When the stopcock is about to rotate into position, the transverse channel aligns with the two side connectors, and the sliding rod contacts the push rod in one side connector. At this time, the sliding rod slides under the action of the push rod, and the sliding rod integrally drives the inner connector to slide and align with the joint cup of the side connector. During this process, the swing of the joint cup compensates for any misalignment between the inner connector and the joint cup.

Description

Technical Field

[0001] This invention relates to the field of valve structure, and in particular to a multi-channel independently controlled multi-way valve device for offshore platform scheduling. Background Technology

[0002] A multi-way valve is a device used to control the direction of fluid flow or distribute fluid, belonging to the fields of mechanical engineering and fluid control systems. It is commonly used in hydraulic systems, pneumatic systems, and chemical equipment to achieve switching and flow distribution between multiple pipelines. A common operating mode of multi-way valves is rotary switching; this type of multi-way valve is also called a plug valve. It is a valve that opens or closes by rotating the plug to connect or separate the passage on the valve body. The plug can be cylindrical or conical. The working principle of a plug valve is to change the size and direction of the plug passage by rotating the plug, thereby regulating and cutting off the fluid. Plug valves are easily adapted to multi-channel structures; multiple side connectors are set on the outer periphery of the valve body, allowing for docking with different side connectors through plug rotation.

[0003] Because of the need for docking between the valve plug and different side connectors, the accuracy of this docking directly affects the valve's operation. In the operating environment of offshore platforms, where pressures are high, the docking process between the valve plug and side connectors becomes even more critical. Currently, docking structures are relatively complex (such as telescopic structures), and the docking process can easily damage the sealing surfaces. Summary of the Invention

[0004] The main objective of this invention is to provide a multi-channel, independently controlled multi-way valve device for offshore platform scheduling, aiming to solve the problems of the complex docking structure of current multi-way valves and the potential for damage to the sealing surface during the docking process.

[0005] To achieve the above objectives, the present invention provides a multi-channel independently controlled multi-way valve device for dispatching marine platforms, comprising:

[0006] The valve body has an opening at the top and a lower connector at the bottom. The inner end of the lower connector extends into the valve body to form an inner seat. The valve body has multiple side holes with joint grooves at their inner ends arranged opposite each other in the circumferential direction.

[0007] Multiple side connectors, including side connectors and joint bowls respectively installed at the outer and inner ends of the side holes, the protruding side of the joint bowl forms a joint fit with the joint groove, the inner end of the side connector is provided with a first bracket, the first bracket is connected with a top rod extending into the joint bowl, the bottom of the joint bowl passes through the top rod, and a first elastic member is provided between the joint bowl and the top rod to press the joint bowl into the joint groove;

[0008] A stopcock is rotatably mounted on the inner seat. The stopcock has a transverse channel extending radially upwards and a vertical channel at its bottom that leads upwards to the transverse channel. An inner cover is installed at the rear end of the transverse channel.

[0009] The connector includes a slide rod and an inner connector. The inner connector is slidably disposed in the transverse channel and partially extends out of the transverse channel. The slide rod extends from outside the inner cover and is connected to the inner connector. The inner connector and the front end of the transverse channel clamp a second elastic member.

[0010] Upper valve cover, installed in the opening;

[0011] The drive unit is installed above the upper valve cover and drives the valve to rotate;

[0012] When the transverse channel is aligned with a pair of side connectors, the outer end of the slide rod is pushed out by a push rod, thereby the inner connector and the joint cup are connected to the side connector.

[0013] Furthermore, a third bracket is provided in the middle of the inner joint, the slide rod is connected to the third bracket, and a third elastic element is compressed between the slide rod and the third bracket.

[0014] Furthermore, a corrugated pipe is connected within the transverse channel between the inner cover and the slide rod.

[0015] Furthermore, an annular groove is provided on the outer side of the inner cover corresponding to the outer periphery of the slide rod, and a sealing ring is connected to the inner cover. When the slide rod is pushed out by the top rod, the sealing ring and the sealing ring cooperate with each other.

[0016] Furthermore, the corresponding ends of the slide rod and the top rod are both spherical.

[0017] Furthermore, a blocking ring is provided on the slide bar corresponding to the inner side of the inner cover. When the second elastic member is in a free state, the blocking ring abuts against the inner cover.

[0018] Furthermore, the side connector and the side hole are connected by bolts or threads.

[0019] Furthermore, the connection between the first bracket and the top rod is a threaded connection.

[0020] Furthermore, the number of side holes is 4, 6, 8, 10, or 12.

[0021] Furthermore, both the first elastic element and the second elastic element are disc springs.

[0022] The present invention provides a multi-channel independently controlled multi-way valve device for marine platform scheduling. The side connector includes a side connector and a swaying joint cup disposed on the side connector. A first elastic element provides sealing and reset force between the joint cup and the joint groove. The connector is slidably disposed in a stopcock. When the stopcock is about to rotate into position, the transverse channel aligns with the two side connectors. The slide rod contacts the top rod in one side connector. At this time, the slide rod slides under the action of the top rod. The slide rod drives the inner connector to slide and dock with the joint cup of the side connector. During this process, the swaying of the joint cup compensates for the misalignment between the inner connector and the joint cup. The rotation of the stopcock provides the power for the slide rod to slide without the need for additional external power. While the operation is smooth, the operating speed of the slide rod can be adjusted by adjusting the rotation speed, ultimately achieving smooth connection and separation of the inner connector and the joint cup.

[0038] Reference Figures 1 to 11 In one embodiment of the present invention, a multi-channel independently controlled multi-way valve device for dispatching marine platforms includes:

[0039] The valve body 100 has an opening 110 at the top and a lower connector 120 at the bottom. The inner end of the lower connector 120 extends into the valve body 100 to form an inner seat 121. The valve body 100 has a plurality of side holes 130 with joint grooves 131 at the inner end, which are arranged opposite each other in the circumferential direction.

[0040] Multiple side connectors 200 include side connectors 210 and joint bowls 220 respectively installed at the outer and inner ends of the side hole 130. The protruding side of the joint bowl 220 forms a joint with the joint groove 131. The inner end of the side connector 210 is provided with a first bracket 211. A push rod 230 extending into the joint bowl 220 is connected to the first bracket 211. The bottom of the joint bowl 220 passes through the push rod 230, and a first elastic member 240 is provided between the joint bowl 220 and the push rod 230 to press the joint bowl 220 into the joint groove 131.

[0041] A stopcock 300 is rotatably mounted on the inner seat 121. The stopcock 300 has a transverse channel 310 extending radially through it, and a vertical channel 320 at its bottom that leads upward to the transverse channel 310. An inner cover 330 is installed at the rear end of the transverse channel 310.

[0042] The connector 400 includes a slide rod 410 and an inner connector 420. The inner connector 420 is slidably disposed in the transverse channel 310 and partially extends out of the transverse channel 310. The slide rod 410 extends from the outer side of the inner cover 330 and is connected to the inner connector 420. The inner connector 420 and the front end of the transverse channel 310 clamp a second elastic member 430.

[0043] Upper valve cover, installed in the opening 110;

[0044] The drive unit is installed above the upper valve cover and drives the valve 300 to rotate;

[0045] When the transverse channel 310 is aligned with a pair of side connectors 200, the outer end of the slide rod 410 is pushed out by a push rod 230, thereby the inner connector 420 and the joint cup 220 are connected to the side connector 210.

[0046] In the current technology, the multi-way valve adopts a relatively complex docking structure (such as a telescopic structure), and the docking process is prone to damage to the sealing surface.

[0047] The multi-channel independently controlled multi-way valve device for marine platform scheduling provided by the present invention includes a valve body 100, multiple side connectors 200, a plug 300, a connector 400, an upper valve cover, and a drive unit.

[0048] The valve body 100 has an opening 110 at the top and a lower connector 120 at the bottom. The inner end of the lower connector 120 extends into the valve body 100 to form an inner seat 121. The bottom of the lower connector 120 can be a flange interface, and the upper end of the lower connector 120 can form an annular support structure to provide a foundation for the installation of the plug 300. The valve body 100 has multiple side holes 130 with inner ends forming joint grooves 131, which are arranged opposite each other in the circumferential direction. The side holes 130 provide a foundation for the installation of the side connector 200. The side holes 130 have a joint groove 131 structure formed at one end inside the valve body 100, providing a foundation for the operation of the side connector 200.

[0049] Multiple side connectors 200 are respectively provided with multiple side holes 130. Each side connector 200 includes a side connector 210 and a joint bowl 220. A flow channel is formed through the central axis of the side connector 200. Specifically, the side connector 210 forms a tubular structure, and the bottom of the joint bowl 220 has a window structure, thus forming a through-through at the central axis of the side connector 200. The side connector 210 is installed from the outer end of the side hole 130, and the joint bowl 220 is installed from the inner end of the side hole 130. The protruding side of the joint bowl 220 forms a joint fit with the inner end of the joint groove 131. A first support 211 is provided at the inner end of the side connector 210, and a push rod 230 extending into the joint bowl 220 is connected to the first support 211. The first support 211 cannot completely close the flow channel of the side connector 210; a window for fluid to pass through is required. Similarly, the bottom of the joint bowl 220 is not completely closed; a window for fluid to pass through is also required. The bottom of the joint cup 220 passes through the top rod 230, and a first elastic member 240 is provided between the joint cup 220 and the top rod 230 to press the joint cup 220 against the joint groove 131. The joint cup 220 and the joint groove 131 form a joint engagement, and under the action of the first elastic member 240, the joint cup 220 and the joint groove 131 form a seal.

[0050] The plug 300 is rotatably mounted on the inner seat 121. The plug 300 has a transverse channel 310 extending radially upwards, and a vertical channel 320 at its bottom leading upwards to the transverse channel 310. The lower connector 120 communicates with the vertical channel 320, and the transverse channel 310 and vertical channel 320 are connected to form a "T" or "Г" shape. An inner cover 330 is installed at the rear end of the transverse channel 310, and the inner cover 330 can be installed on the transverse channel 310 by bolts or threaded connections, etc.

[0051] The connector 400 includes a slide bar 410 and an inner connector 420. The inner connector 420 is slidably disposed in the transverse channel 310. The inner connector 420 is completely disengaged by the front end of the transverse channel 310, while partially protruding from the transverse channel 310. The slide bar 410 passes through the inner cover 330 and connects to the inner connector 420. The inner connector 420 and the front end of the transverse channel 310 clamp a second elastic member 430, which presses the inner connector 420 toward the inner cover 330.

[0052] The upper valve cover is installed at opening 110.

[0053] The drive unit is mounted above the upper valve cover and drives the valve stem to rotate 300 degrees. The drive unit can be of various models, depending on its ability to perform accurate angular rotation. For example, the drive unit could be a servo motor equipped with angle monitoring.

[0054] When the transverse channel 310 is aligned with a pair of side joints 200, the outer end of the slide rod 410 is pushed out by a push rod 230, so that the inner joint 420 and the joint bowl 220 are connected to the side joint 210. During this process, the swing of the joint bowl 220 compensates for the misalignment between the inner joint 420 and the joint bowl 220.

[0055] During operation, after all components are installed in place, as the stopcock 300 is about to rotate into position, the transverse channel 310 aligns with the two side connectors 200. The slide rod 410 contacts the push rod 230 in one side connector 200. At this point, the slide rod 410 slides under the action of the push rod 230, driving the inner connector 420 to slide and engage with the joint cup 220 of the side connector 200. During this process, the oscillation of the joint cup 220 compensates for any misalignment between the inner connector 420 and the joint cup 220. In this process, the rotation of the stopcock 300 provides the power for the slide rod 410 to slide smoothly. Furthermore, the operating speed of the slide rod 410 can be adjusted by regulating the rotation speed, ultimately achieving smooth engagement and disengagement of the inner connector 420 and the joint cup 220. As the stopcock 300 continues to rotate, the joint cup 220 swings together with the inner connector 420 on the stopcock 300 to a certain extent until it disengages. The elastic action of the second elastic element 430 resets the connector 400, and the first elastic element 240 resets the joint cup 220. It should be noted that the dimensions in the accompanying drawings of this invention have been modified for illustrative purposes.

[0056] In summary, the side connector 200 includes a side connector 210 and a spherical cup 220 that is oscillatingly disposed on the side connector 210. The first elastic element 240 provides sealing and restoring force between the joint cup 220 and the joint groove 131; the joint portion 400 is slidably disposed in the plug 300. When the plug 300 is about to rotate into place, the transverse channel 310 aligns with the two side joint portions 200, and the slide rod 410 contacts the top rod 230 in one side joint portion 200. At this time, the slide rod 410 slides under the action of the top rod 230. The slide rod 410 drives the inner joint 420 to slide and dock with the joint cup 220 of the side joint portion 200. During this process, the swing of the joint cup 220 compensates for the misalignment between the inner joint 420 and the joint cup 220; the rotation of the plug 300 provides the power for the slide rod 410 to slide without the need for additional external power. While the operation is smooth, the operating speed of the slide rod 410 can be adjusted by adjusting the rotation speed, and finally the smooth connection and separation of the inner joint 420 and the joint cup 220 are achieved.

[0057] Reference Figures 3 to 4 In one embodiment, a third support 421 is provided in the middle of the inner connector 420, the slide rod 410 is connected to the third support 421, and a third elastic member 440 is compressed between the slide rod 410 and the third support 421.

[0058] In this embodiment, considering that in some cases, the mating surface between the inner connector 420 and the joint bowl 220 may not be provided with an elastic sealing ring, or the materials of the slide rod 410, inner connector 420, and joint bowl 220 may lack sufficient elasticity; therefore, the sealing effect formed between the inner connector 420 and joint bowl 220 during the driving action of the push rod 230 on the slide rod 410 is insufficient. Thus, a third support 421 and a third elastic element 440 are added. The elastic force of the third elastic element 440 drives the slide rod 410 and inner connector 420 away from each other. The slide rod 410 drives the inner connector 420 through the third support 421. Therefore, when the inner connector 420 is mated with the joint bowl 220, the elasticity of the third elastic element 440 provides the sealing force between the inner connector 420 and joint bowl 220. The third support 421 cannot completely seal the flow channel of the inner connector 420 and needs to be provided with a window for fluid to pass through.

[0059] In one embodiment, a bellows is connected within the transverse channel 310 between the inner cover 330 and the slide bar 410.

[0060] In this embodiment, the introduction of a bellows creates a seal between the slide rod 410 and the inner cover 330, which is advantageous under harsh working conditions. The bellows can be connected to the slide rod 410 and the inner cover 330 in various ways, such as by welding. The bellows also prevents the slide rod 410 from sliding to an unsuitable working position or even coming off.

[0061] In one embodiment, an annular groove is provided on the outer side of the inner cover 330 corresponding to the outer periphery of the slide rod 410, and a sealing ring is connected to the inner cover 330. When the slide rod 410 is pushed out by the top rod 230, the sealing ring and the sealing ring cooperate with each other.

[0062] In this embodiment, considering the high working pressure during the operation of the multi-way valve device on the offshore platform, the sealing effect between the slide rod 410 and the inner cover 330 is crucial. Therefore, an annular groove is provided at the corresponding position of the inner cover 330, and a sealing ring is provided at the slide rod 410, so that the seal between the two can ensure stable use during operation.

[0063] Reference Figures 10 to 11 In one embodiment, the corresponding ends of the slide bar 410 and the top bar 230 are both spherical.

[0064] In this embodiment, the docking position of the slide rod 410 and the push rod 230 is set as a ball, so that the interaction between the slide rod 410 and the push rod 230 is smoother during the rotation of the stopcock 300.

[0065] In one embodiment, a blocking ring is provided on the slide bar 410 corresponding to the inner side of the inner cover 330. When the second elastic member 430 is in a free state, the blocking ring abuts against the inner cover 330.

[0066] In this embodiment, a structural form is provided to prevent excessive displacement of the slide rod 410. After the slide rod 410 separates from the top rod 230, the slide rod 410 slides a certain distance towards the inner cover 330 under the action of the second elastic element 430. Then, the blocking ring abuts against the inner cover 330, preventing the slide rod 410 from sliding to an unsuitable working position or even dislodging. In other embodiments, the abnormal displacement of the slide rod 410 can be prevented in other ways, such as by providing an additional elastic element to limit excessive movement of the inner connector 420 towards the inner cover 330.

[0067] In one embodiment, the side connector 210 and the side hole 130 are connected by bolts or threads.

[0068] In this embodiment, the connection method between the side connector 210 and the side hole 130 is defined, which is convenient and structurally stable. The outer wall of the side connector 210 can be provided with external threads, while the inner wall of the side hole 130 is provided with internal threads, thereby achieving a threaded connection between the two; the side connector 210 and the side hole 130 can be installed using multiple bolts.

[0069] In one embodiment, the connection between the first bracket 211 and the top rod 230 is a threaded connection.

[0070] In this embodiment, the connection between the first bracket 211 and the push rod 230 is limited to a threaded connection, which is simple and convenient, and the adjustment of the screw depth of the push rod 230 can realize the adjustment of the working position. After the position is set, the push rod 230 and the first bracket 211 can also be fixed by means of pins or other means to prevent the fixation between the first bracket 211 and the push rod 230 from loosening.

[0071] In one embodiment, the number of side holes 130 is 4, 6, 8, 10, or 12.

[0072] In this embodiment, the number of several common side holes 130 is limited to meet the usage requirements. Of course, the side holes 130 still appear in pairs.

[0073] In one embodiment, both the first elastic element 240 and the second elastic element 430 are butterfly springs.

[0074] In this embodiment, the first elastic element 240 and the second elastic element 430 are constrained as butterfly springs, thereby providing a stable elastic force to meet the usage requirements.

[0075] In summary, the multi-channel independently controlled marine platform scheduling multi-way valve device provided by the present invention includes a side connector 200 comprising a side connector 210 and a swaying joint cup 220 disposed on the side connector 210. The first elastic element 240 provides sealing and restoring force between the joint cup 220 and the joint groove 131; the joint portion 400 is slidably disposed in the plug 300. When the plug 300 is about to rotate into place, the transverse channel 310 aligns with the two side joint portions 200, and the slide rod 410 contacts the top rod 230 in one side joint portion 200. At this time, the slide rod 410 slides under the action of the top rod 230. The slide rod 410 drives the inner joint 420 to slide and dock with the joint cup 220 of the side joint portion 200. During this process, the swing of the joint cup 220 compensates for the misalignment between the inner joint 420 and the joint cup 220; the rotation of the plug 300 provides the power for the slide rod 410 to slide without the need for additional external power. While the operation is smooth, the operating speed of the slide rod 410 can be adjusted by adjusting the rotation speed, and finally the smooth connection and separation of the inner joint 420 and the joint cup 220 are achieved.

[0076] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
