Description

Technical Field

[0001] This invention relates to the field of valve technology, and more particularly to a combined liquid hydrogen valve. Background Technology

[0002] With the development of science and technology, the requirements for gases in many fields such as large-scale integrated circuits, oil processing, and liquid hydrogen are becoming increasingly serious. In recent years, the advocacy of low carbon and environmental protection has brought the use of hydrogen into everyone's view. In the process of transporting hydrogen, liquid hydrogen is often used, and liquid hydrogen valves are required in the process of transporting liquid hydrogen.

[0003] Existing hydrogen valves are mostly used in high positions or in confined spaces, making manual control difficult. Furthermore, due to mechanical stability considerations, there are no readily available structures for automatic control, hindering large-scale automated management. Additionally, the valve's internal opening and closing status cannot be presented in a data-driven and intuitive manner, reducing the convenience of widespread use in this field. Moreover, existing combined valves cannot quickly and uniformly close asynchronously controlled ports, making it difficult to manage valve opening and closing in a timely and efficient manner in special circumstances. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in manually controlling valves due to their high placement or limited space, the lack of readily available structures for automatic control to ensure mechanical stability, the difficulty in large-scale automatic management, and the inability to provide intuitive data-driven representation of the valve's internal opening and closing status. Therefore, this invention proposes a combined liquid hydrogen valve.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A combined liquid hydrogen valve includes an upper valve shell, a motor, a lower shell, and adjustable pipes. The motor is detachably mounted to the top of the lower shell via a flange. The adjustable pipes are arranged in six sets, which are welded in a ring at equal intervals inside the lower shell. The motor is fixedly mounted at the center of the top of the upper valve shell by bolts. The output end of the motor passes through the upper valve shell and extends into the interior of the upper valve shell, where a screw is fixedly mounted via a coupling. A support plate is detachably mounted on the inner wall of the lower shell by bolts. A gate drive sleeve is slidably fitted on the top of the screw surface.

[0007] Each of the six sets of adjustable pipes is provided with a driven pipe opening and closing mechanism on the side that is close to each other. The driven pipe opening and closing mechanism is used to control and adjust the gas flow rate of the adjustable pipe.

[0008] The top of the support plate frame is provided with a multi-axis asynchronous drive mechanism, which is used to synchronously or asynchronously drive multiple sets of driven pipe opening and closing mechanisms inside the adjustable pipe.

[0009] The top of the screw surface is fitted with a multi-pipe synchronous sealing mechanism, which is used to quickly close multiple pipes under special circumstances.

[0010] Preferably, one set of the driven pipe opening and closing mechanisms includes a mounting bracket, a rotary drive shaft, a worm gear, a stabilizing bracket, and a pipe sealing plate. The mounting bracket is welded to the top of the adjustable pipe surface near the screw. One end of the stabilizing bracket is welded and fixed to the adjustable pipe surface, and the other end of the stabilizing bracket is rotatably mounted to the rotary drive shaft. The rotary drive shaft is rotatably mounted inside the mounting bracket. The worm gear is keyed to the rotary drive shaft. The pipe sealing plate is welded to the surface of the rotary drive shaft and located between the mounting bracket and the worm gear.

[0011] Preferably, the multi-axis asynchronous drive mechanism includes an asynchronous control lifting assembly, a linkage coupling assembly, an independent pipe drive sleeve, six fixing ribs, a gear ring, a gear, a worm shaft, a pressure plate, and a spring. The independent pipe drive sleeve is movably fitted onto the bottom of the screw surface. The six fixing ribs are welded to the surface of the independent pipe drive sleeve and are distributed equidistantly in a ring. The gear ring is welded and fixed to the end of the six fixing ribs away from the independent pipe drive sleeve. The worm shaft is provided in six sets and is rotatably mounted on the top of the support plate in a ring. The surface of the worm shaft has a groove. The gear is slidably mounted on the top of the worm shaft surface through the groove. The spring is fitted onto the surface of the worm shaft and is located on top of the gear. The pressure plate is welded to the top of the worm shaft. The top of the spring contacts the bottom of the pressure plate, and the bottom of the spring is in movable contact with the top of the gear. The worm shaft meshes with the worm wheel. The asynchronous control lifting assembly is used to individually control the lifting of the six gears to ensure asynchronous drive during operation. The linkage coupling assembly is used to control the installation relationship between the independent pipe drive sleeve and the screw, realizing convenient operation of fixing and separating, and facilitating automatic control.

[0012] Preferably, the asynchronous control lifting assembly includes an electromagnetic push rod II and a drive lifting frame. The electromagnetic push rod II is fixedly installed on the top of the support plate frame by bolts. There are six electromagnetic push rod II, which are evenly distributed in a ring on one side of the gear. The drive lifting frame is slidably sleeved on the surface of the worm shaft and located between the support plate frame and the gear. The drive lifting frame is welded and fixed to the output end of the electromagnetic push rod II.

[0013] Preferably, the linkage coupling assembly includes a locking block, an electromagnetic push rod, and a locking tooth groove. The electromagnetic push rod is detachably embedded in one side of the independent pipe drive sleeve by bolts. The locking block is slidably installed on the inner wall of the independent pipe drive sleeve near the electromagnetic push rod. The locking tooth groove is formed at the bottom of the screw surface, and the locking block and the locking tooth groove are engaged.

[0014] Preferably, the multi-pipe synchronous sealing mechanism includes a hexagonal gate ring, a sealing gate shell, a reinforcing synchronous rib, and an asynchronous linkage assembly. The sealing gate shell is connected to the interior of the adjustable pipe. The hexagonal gate ring is slidably installed inside the sealing gate shell. The reinforcing synchronous rib is welded to the inner side of the hexagonal gate ring. The side of the reinforcing synchronous rib away from the hexagonal gate ring is welded and fixed to the gate drive sleeve. The asynchronous linkage assembly is used to control the fixed and disengaged connection relationship between the gate drive sleeve and the screw, ensuring that the screw can arbitrarily control the rotation state of the gate drive sleeve.

[0015] Preferably, the asynchronous linkage component includes an electromagnetic push rod three, a fixed frame, and a semi-circular threaded block. The electromagnetic push rod three is fixed to one side of the surface of the gate drive sleeve by bolts. The fixed frame is fixedly installed at the output end of the electromagnetic push rod three. The electromagnetic push rod three is welded to the end of the fixed frame away from the electromagnetic push rod three. The side of the semi-circular threaded block away from the fixed frame is threadedly connected to the screw.

[0016] Preferably, a sealing reinforcement ring is welded to the bottom of the adjustable pipe surface near the pipe sealing plate, and the sealing reinforcement ring is used in conjunction with the pipe sealing plate for sealing.

[0017] Beneficial effects

[0018] 1. In this invention, by setting up a mounting bracket, a rotary drive shaft, a worm gear, a stabilizing bracket, and a pipe sealing plate, the worm gear can cooperate with the worm shaft to achieve driven operation. When the worm gear rotates, it drives the rotary drive shaft. The rotary drive shaft drives the pipe sealing plate to twist and achieve an angled interlacing with the adjustable pipe, thereby realizing fine adjustment of the valve opening angle. At the same time, the mounting bracket and the stabilizing bracket can provide stable support for the rotation of the rotary drive shaft, ensuring the accuracy of the rotary drive shaft's rotation.

[0019] 2. In this invention, by setting up an asynchronous control lifting component, a linkage coupling component, an independent pipe drive sleeve, six fixed ribs, a gear ring, gears, a worm shaft, a pressure plate, and a spring, the independent pipe drive sleeve can achieve follow-drive after being fixed to the screw through the linkage coupling component. Subsequently, the independent pipe drive sleeve drives the fixed ribs to rotate, and the fixed ribs drive the gear ring to rotate the six sets of gears. If it is necessary to asynchronously control some of the gears, the asynchronous control lifting component can lift the gears that do not need to be driven and separate them from the gear ring to complete the asynchronous control operation.

[0020] 3. In this invention, by setting up an electromagnetic push rod two and a drive lifting frame, the electromagnetic push rod two can drive the drive lifting frame to lift upward through the output end after it is started. At this time, the drive lifting frame can drive the gear to separate from the gear ring upward. At the same time, the spring will be compressed when the gear is upward. When the electromagnetic push rod two is closed, the drive lifting frame will be pushed upward by the spring released by the elastic force. Then the gear will quickly mesh with the gear ring through the chamfer structure on the teeth.

[0021] 4. In this invention, by setting a locking block, an electromagnetic push rod, and a locking tooth groove, it is convenient to activate the electromagnetic push rod to drive the locking block and the locking tooth groove to engage and lock when it is necessary to perform fixed synchronous control of the independent pipe drive sleeve and the screw. At this time, the rotation of the screw can drive the independent pipe drive sleeve to rotate. When the independent pipe drive sleeve does not need to rotate synchronously with the screw, closing the electromagnetic push rod can reset the elastic structure inside the electromagnetic push rod and drive the locking block and the locking tooth groove to separate.

[0022] 5. In this invention, by setting a hexagonal gate ring, a sealing gate shell, a reinforcing synchronous rib, and an asynchronous linkage component, the reinforcing synchronous rib can establish a fixed relationship with the gate drive sleeve through the asynchronous linkage component. Subsequently, the up-and-down lifting driving force of the gate drive sleeve can drive the reinforcing synchronous rib and the hexagonal gate ring to move downward and complete the sealing gate closing operation with the sealing gate shell. When the asynchronous linkage component separates the connection between the reinforcing synchronous rib and the gate drive sleeve, it will not be driven by the screw.

[0023] 6. In this invention, by setting up an electromagnetic push rod three, a fixed frame, and a semi-circular threaded block, the electromagnetic push rod three can drive the fixed frame to move laterally after it is started. At this time, the fixed frame can drive the semi-circular threaded block to abut against the screw. After abutting, the threaded connection between the semi-circular threaded block and the screw can prevent the reinforcing synchronous rib and the gate drive sleeve, which are limited by the hexagonal gate ring, from twisting and moving up and down. By closing the electromagnetic push rod three, the semi-circular threaded block can be separated from the gate drive sleeve, ensuring that the rotating screw will not drive the semi-circular threaded block to move.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-8 A combined liquid hydrogen valve includes an upper valve shell 1, a motor 2, a lower shell 3, and adjustable pipes 4. The motor 2 is detachably installed on the top of the lower shell 3 via a flange. The adjustable pipes 4 are provided in six sets, and the six sets of adjustable pipes 4 are welded in a ring at equal intervals inside the lower shell 3. The motor 2 is fixedly installed at the center of the top of the upper valve shell 1 by bolts. The output end of the motor 2 passes through the upper valve shell 1 and extends into the interior of the upper valve shell 1. A screw 5 is fixedly installed on the upper valve shell 1 via a coupling. A support plate frame 12 is detachably installed on the inner wall of the lower shell 3 by bolts. A gate drive sleeve 6 is slidably sleeved on the top of the surface of the screw 5.

[0036] Each of the six sets of adjustable pipes 4 is equipped with a driven pipe opening and closing mechanism on one side that is close to each other. The driven pipe opening and closing mechanism is used to control and adjust the gas flow rate of the adjustable pipes 4.

[0037] The top of the support plate 12 is provided with a multi-axis asynchronous drive mechanism, which is used to synchronously or asynchronously drive the driven pipe opening and closing mechanism inside multiple sets of adjustable pipes 4.

[0038] The top of the screw 5 surface is fitted with a multi-pipe synchronous sealing mechanism, which is used to quickly close multiple pipes in special circumstances.

[0039] Example 2

[0040] Improvements based on Embodiment 1: Includes valve upper shell 1, motor 2, lower shell 3 and adjustable pipe 4. Motor 2 is detachably installed on the top of lower shell 3 via flange. The adjustable pipe 4 is provided in six sets, and the six sets of adjustable pipe 4 are welded in a ring at equal intervals inside the lower shell 3. Motor 2 is fixedly installed at the top center of valve upper shell 1 by bolts. The output end of motor 2 passes through valve upper shell 1 and extends into the interior of valve upper shell 1. A screw 5 is fixedly installed on it via coupling. A support plate frame 12 is detachably installed on the inner wall of lower shell 3 by bolts. A gate drive sleeve 6 is slidably sleeved on the top of the surface of screw 5.

[0041] Each of the six sets of adjustable pipes 4 has a driven pipe opening and closing mechanism on one side close to each other. One set of driven pipe opening and closing mechanisms includes a mounting bracket 112, a rotary drive shaft 111, a worm gear 113, a stabilizing bracket 114, and a pipe sealing plate 116. The mounting bracket 112 is welded to the top of the adjustable pipe 4 near the screw 5. One end of the stabilizing bracket 114 is welded and fixed to the surface of the adjustable pipe 4, and the other end of the stabilizing bracket 114 is rotatably mounted to the rotary drive shaft 111. The rotary drive shaft 111 is rotatably mounted inside the mounting bracket 112. The worm gear 113 is keyed to the rotary drive shaft 111. The pipe sealing plate 116 is welded to the surface of the rotary drive shaft 111 and located between the mounting bracket 112 and the worm gear 113. A sealing reinforcement ring 115 is welded to the bottom of the adjustable pipe 4 near the pipe sealing plate 116 for sealing reinforcement. The ring 115 works in conjunction with the pipe sealing plate 116 for sealing. The sealing and reinforcing ring 115 can clamp and limit the pipe sealing plate 116 at the end of the adjustable pipe 4, ensuring that the pipe sealing plate 116 will not tilt or deform when twisted, improving the stability of the opening and closing drive, and preventing deformation from affecting the sealing performance. The worm gear 113 can work with the worm shaft 93 to achieve driven drive. When the worm gear 113 rotates, it drives the rotary drive shaft 111. The rotary drive shaft 111 drives the pipe sealing plate 116 to twist and achieve an angled and intersecting relationship with the adjustable pipe 4, realizing fine adjustment of the valve opening angle. At the same time, the mounting bracket 112 and the stabilizing bracket 114 can provide stable support for the rotation of the rotary drive shaft 111, ensuring the accuracy of the rotary drive shaft 111's rotation drive. The driven pipe opening and closing mechanism is used to control and adjust the gas flow rate of the adjustable pipe 4.

[0042] The top of the support plate frame 12 is equipped with a multi-axis asynchronous drive mechanism, which includes an asynchronous control lifting component, a linkage coupling component, an independent pipe drive sleeve 8, six fixing ribs 9, a gear ring 91, a gear 92, a worm shaft 93, a pressure plate 94, and a spring 95. The independent pipe drive sleeve 8 is movably fitted onto the bottom of the screw 5 surface. The six fixing ribs 9 are welded to the surface of the independent pipe drive sleeve 8 and are distributed in a ring at equal intervals. The gear ring 91 is welded and fixed to the end of the six fixing ribs 9 away from the independent pipe drive sleeve 8. The worm shaft 93 is provided in six sets and is rotatably mounted on the top of the support plate frame 12 in a ring at equal intervals. The surface of the worm shaft 93 has a groove. The gear 92 is slidably mounted on the top of the worm shaft 93 surface through the groove. The spring 95 is fitted onto the worm. The worm shaft 93 is located on the surface of the shaft 93 and on top of the gear 92. A pressure plate 94 is welded to the top of the worm shaft 93. The top of the spring 95 contacts the bottom of the pressure plate 94, and the bottom of the spring 95 is in movable contact with the top of the gear 92. The worm shaft 93 meshes with the worm wheel 113. The asynchronous control lifting assembly is used to individually control the lifting of the six gears 92, ensuring asynchronous drive during operation. The asynchronous control lifting assembly includes an electromagnetic push rod 101 and a drive lifting frame 102. The electromagnetic push rod 101 is bolted to the top of the support plate frame 12. Six electromagnetic push rods 101 are arranged in a ring and evenly spaced on one side of the gear 92. The drive lifting frame 102 is slidably sleeved on the surface of the worm shaft 93 and located between the support plate frame 12 and the gear 92. The drive lifting frame 102 is welded and fixed to the output end of the electromagnetic push rod 101. After the electromagnetic push rod 101 is started, it can drive the drive lifting frame 102 to rise through the output end. At this time, the drive lifting frame 102 can drive the gear 92 to separate from the gear ring 91. At the same time, when the gear 92 rises, the spring 95 will be compressed. When the electromagnetic push rod 101 is closed, the drive lifting frame 102 will be pushed upward by the spring 95 released by the elastic force. Then, the gear 92 quickly meshes with the gear ring 91 through the chamfer structure on the teeth. The linkage coupling component is used to control the installation relationship between the independent pipe drive sleeve 8 and the screw 5, realizing convenient operation of fixing and separating, and facilitating automatic control. The linkage coupling component includes a locking block 81, an electromagnetic push rod 82, and a locking tooth. The electromagnetic push rod 82 is detachably bolted to one side of the independent pipe drive sleeve 8. A locking block 81 is slidably mounted on the inner wall of the independent pipe drive sleeve 8 near the electromagnetic push rod 82. A locking tooth groove 83 is formed at the bottom of the screw rod 5 surface. The locking block 81 engages with the locking tooth groove 83. When synchronous control of the independent pipe drive sleeve 8 and the screw rod 5 is required, the electromagnetic push rod 82 is activated, causing the locking block 81 to mesh and engage with the locking tooth groove 83. At this time, the rotation of the screw rod 5 drives the independent pipe drive sleeve 8 to rotate. When the independent pipe drive sleeve 8 does not need to rotate synchronously with the screw rod 5, closing the electromagnetic push rod 82 allows the internal elastic structure of the electromagnetic push rod 82 to reset, causing the locking block 81 to separate from the locking tooth groove 83.After the independent pipe drive sleeve 8 is fixed to the screw 5 through the linkage coupling component, it can achieve follow drive. Subsequently, the independent pipe drive sleeve 8 drives the fixing rib 9 to rotate, and the fixing rib 9 drives the gear ring 91 to rotate, which in turn rotates the six sets of gears 92. If it is necessary to asynchronously control some of the gears 92, the asynchronous control lifting component can be used to lift the gears 92 that do not need to be driven and separate them from the gear ring 91, thus completing the asynchronous control operation. The multi-axis asynchronous drive mechanism is used to synchronously or asynchronously drive the driven pipe opening and closing mechanisms inside multiple adjustable pipes 4.

[0043] A multi-tube synchronous sealing mechanism is fitted onto the top of the screw 5 surface. This mechanism includes a hexagonal gate ring 7, a sealing gate housing 71, a reinforcing synchronous rib 72, and an asynchronous linkage assembly. The sealing gate housing 71 is connected to the interior of the adjustable pipe 4. The hexagonal gate ring 7 is slidably installed inside the sealing gate housing 71. The reinforcing synchronous rib 72 is welded to the inner side of the hexagonal gate ring 7. The side of the reinforcing synchronous rib 72 away from the hexagonal gate ring 7 is welded and fixed to the gate drive sleeve 6. The asynchronous linkage assembly is used to control the gate drive. The fixed and disengaged connection between sleeve 6 and screw 5 ensures that screw 5 can arbitrarily control the rotation state of gate drive sleeve 6. Reinforcing synchronous rib 72 can establish a fixed relationship with gate drive sleeve 6 through asynchronous linkage components. Subsequently, the up-and-down lifting driving force of gate drive sleeve 6 can drive reinforcing synchronous rib 72 and hexagonal gate ring 7 to move downwards and complete the sealing gate shell 71 to perform the sealing and closing operation. When the asynchronous linkage components disengage the connection between reinforcing synchronous rib 72 and gate drive sleeve 6, it will not be driven by screw 5. The multi-pipe synchronous sealing mechanism is used to quickly close multiple pipes under special circumstances. The asynchronous linkage component includes an electromagnetic push rod 63, a fixed frame 62, and a semi-circular threaded block 61. The electromagnetic push rod 63 is fixed to one side of the surface of the gate drive sleeve 6 by bolts. The fixed frame 62 is fixedly installed at the output end of the electromagnetic push rod 63. The electromagnetic push rod 63 is welded to the end of the fixed frame 62 away from the electromagnetic push rod 63. The semi-circular threaded block 61 is threadedly connected to the screw 5 on the side away from the fixed frame 62. After the electromagnetic push rod 63 is started, it can drive the fixed frame 62 to move laterally. At this time, the fixed frame 62 can drive the semi-circular threaded block 61 to abut against the screw 5. After abutting, the threaded connection between the semi-circular threaded block 61 and the screw 5 can prevent the reinforced synchronous rib 72, which is limited by the hexagonal gate ring 7, and the gate drive sleeve 6 from twisting and moving up and down. By closing the electromagnetic push rod 63, the semi-circular threaded block 61 can be separated from the gate drive sleeve 6, ensuring that the rotating screw 5 will not drive the semi-circular threaded block 61 to move.

[0044] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor, electromagnetic push rod three, electromagnetic push rod one and electromagnetic push rod two are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0045] In this invention, when it is necessary to individually control one to five sets of adjustable pipes 4, it is necessary to close the electromagnetic push rod 3 63. Closing the electromagnetic push rod 3 63 can separate the semi-circular threaded block 61 from the gate drive sleeve 6, ensuring that the rotating screw 5 will not cause the semi-circular threaded block 61 to move up and down. Then, according to the pipe position that needs to be individually controlled, the electromagnetic push rod 2 101 above the pipe that does not need to be controlled is activated. After the electromagnetic push rod 2 101 is activated, it can drive the drive lifting frame 102 to lift upward through the output end. At this time, the drive lifting frame 102 can drive the gear 92 to move upward and engage with the gear ring 91. Separate the gear ring 91 to ensure it does not drive the gear 92 to rotate. Then, activate the electromagnetic push rod 82 to engage the locking block 81 with the locking tooth groove 83. At this time, the screw 5 rotates, driving the independent pipe drive sleeve 8 to rotate. Subsequently, the motor 2 is activated to drive the screw 5 to rotate. The screw 5, through the locking tooth groove 83 and the locking block 81, drives the fixing rib 9 to rotate. Then, the fixing rib 9 drives the gear ring 91 to rotate, corresponding to the five sets of independently controlled gears 92 that need to be rotated. At this time, the rotation of the gear 92, through meshing with the worm gear 113, drives the worm gear 113 to rotate. After the worm gear 113 rotates, it drives the rotary drive shaft 111. The rotary drive shaft 111 drives the pipe sealing plate 116 to twist and achieve an angled interlacing with the adjustable pipe 4, thereby achieving fine adjustment of the valve opening angle. In special circumstances, the electromagnetic push rod 63 can be activated. After activation, it can drive the fixed frame 62 to move laterally. At this time, the fixed frame 62 can drive the semi-circular threaded block 61 to abut against the screw 5. After abutting, the threaded connection between the semi-circular threaded block 61 and the screw 5 can prevent the reinforcing synchronous rib 72, which is limited by the hexagonal gate ring 7, from twisting with the gate drive sleeve 6. The rotation causes the gate drive sleeve 6 to move up and down following the semi-circular threaded block 61. The downward movement of the gate drive sleeve 6 drives the reinforcing synchronous rib 72 and the hexagonal gate ring 7 to move downward and seal with the sealing gate shell 71, sealing the pipe opening of the adjustable pipe 4 and completing the rapid sealing of the six pipe openings. In order to ensure that the original unfolding direction of the pipe sealing plate 116 is not affected when closing, the electromagnetic push rod 82 can be closed to reset the elastic structure inside the electromagnetic push rod 82, causing the locking block 81 to separate from the locking tooth groove 83, ensuring that the normal flow rate can be quickly restored after the emergency is resolved.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
