Description

Technical Field

[0001] This invention relates to the field of valve technology, specifically a leak-proof hydrogen valve. Background Technology

[0002] Gas extraction and refining is a combination of two key links in the energy industry, involving the extraction and processing of natural gas. Hydrogen, as a clean energy source, can be extracted through steam methane reforming. Hydrogen valves are devices specifically designed to control the flow of hydrogen. Hydrogen molecules are small and easily permeate metal lattices, leading to "hydrogen embrittlement." The main body material of hydrogen valves must be made of stainless steel, nickel-based alloys, or copper alloys with strong resistance to hydrogen embrittlement. Valve leakage usually occurs at the connection between the rotary handle and the valve stem. Long-term friction between the valve stem and the valve body can wear down the sealing ring or packing, causing gas to leak from the gaps. Incorrect installation direction can also cause leakage. Some valves have flow direction requirements; reverse installation may lead to abnormal internal pressure, forcing open the seals and making the valve prone to loose closure and leakage.

[0003] Chinese patent CN119665139A discloses a sealing valve device for hydrogen storage, comprising a pneumatic main body for power, a venting device for controlling hydrogen flow, a sealing device for sealing the inlet of the venting device during replacement, and a movable main body within the pneumatic main body for controlling the venting and sealing of the venting device. The venting device is fixedly connected to the rear of the pneumatic main body, and the front end of the movable main body is disposed within the pneumatic main body. The sealing device is disposed within the venting device. The venting device includes a venting block, a sealing gasket, a baffle, a rubber block, a sealing main body, and a housing. The rear of the housing is fixedly connected to the pneumatic main body, and bolts are fixedly connected to the left and right sides of the front of the housing. The bolts penetrate the baffle, and nuts are spirally connected to the outer side of the bolts. The nuts fit tightly against the baffle. There are eight rubber blocks in total, and the rubber blocks are evenly fixed in groups of four on the left and right sides behind the baffle. The side of the rubber block away from the baffle fits tightly against the housing. The sealing gasket is fixed behind the venting block, and the other side of the sealing gasket fits tightly against the housing.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot prevent leakage caused by aging of sealing components when the valve is opened and closed through contactless transmission, nor can it allow the valve to be installed regardless of whether it is an inlet or outlet through double sealing.

[0006] Based on this, the present invention designs a leak-proof hydrogen valve to solve the above problems. Summary of the Invention

[0007] In view of the above-mentioned shortcomings of the prior art, the present invention provides a leak-proof hydrogen valve.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A leak-proof hydrogen valve includes a horizontal pipe and further comprises: a multi-angle mounting mechanism, a bidirectional sealing mechanism, a contactless driving mechanism, and a synchronization mechanism. Two of the multi-angle mounting mechanisms are mounted on the left and right sides of the horizontal pipe, two of the bidirectional sealing mechanisms are mounted on the middle side of the horizontal pipe, the contactless driving mechanism is mounted on the bidirectional sealing mechanism, and the synchronization mechanism is mounted on the contactless driving mechanism. The contactless driving mechanism includes: an inner shell, an inner rotating disk, an outer shell, an outer rotating disk, and permanent magnets. The inner shell is fixedly mounted on the outer shell. The inner rotating disk is rotatably connected to the upper side of the inner shell via a rotating shaft. The outer shell is fixedly mounted on the upper side of the inner shell. The outer rotating disk is rotatably connected to the upper side of the outer shell via a rotating shaft. Multiple permanent magnets are fixedly mounted on both the inner and outer rotating disks. The permanent magnets are arranged in a circular array around the center of the inner rotating disk on both the inner and outer rotating disks, and adjacent permanent magnets attract each other.

[0010] Furthermore, a sealing ring is fixedly installed between the inner and outer turntables, and a rotating handle is fixedly installed on the upper side of the shaft of the outer turntable.

[0011] Furthermore, the bidirectional sealing mechanism includes: a sliding block, a sealing gasket, and a first threaded rod. The sliding block is slidably connected to the middle side of the horizontal tube, the sealing gasket is fixedly installed at one end of the sliding block near the center of the horizontal tube, one end of the first threaded rod is threadedly connected to the end of the sliding block away from the center of the horizontal tube, and the other end of the first threaded rod is fixedly connected to the rotating shaft of the inner turntable.

[0012] Furthermore, the synchronization mechanism includes: a driving bevel gear, an L-shaped bracket, and a driven bevel gear. The driving bevel gear is fixedly mounted on the outer turntable shaft and is located between the outer turntable and the rotating handle. The L-shaped bracket is fixedly mounted on the outer shell. The two driven bevel gears are rotatably connected to the L-shaped bracket and are fixedly connected to the same shaft. The rear driven bevel gear meshes with the driving bevel gear.

[0013] Furthermore, the synchronization mechanism includes a transmission assembly mounted on an L-shaped bracket. The transmission assembly includes a connecting rod and a transmission bevel gear. The connecting rod is rotatably connected to two L-shaped brackets, and the two transmission bevel gears are fixedly mounted on the upper and lower ends of the connecting rod. The transmission bevel gears and the front driven bevel gear mesh with each other.

[0014] Furthermore, flanges are fixedly installed on both the left and right sides of the horizontal tube.

[0015] Furthermore, the multi-angle mounting mechanism includes: a collar, a support frame, and fasteners. The collar is slidably connected to the horizontal tube, the support frame is fixedly installed on the collar, and a plurality of fasteners are threadedly connected to the collar, with one end of each fastener tightly abutting the outer wall of the horizontal tube.

[0016] Furthermore, the multi-angle installation mechanism also includes: a height adjustment assembly, two of which are installed on the front and rear sides of the support frame. The height adjustment assembly includes: a second threaded rod, a rotating rod, and a base plate. One end of the second threaded rod is rotatably connected to the support frame. The rotating rod is threadedly connected to the end of the second threaded rod away from the support frame. The base plate is hinged to the end of the rotating rod away from the second threaded rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention drives the outer turntable of the contactless drive mechanism to rotate by rotating the handle. The rotation of the outer turntable drives the permanent magnet on the outer turntable to rotate. The rotation of the permanent magnet on the outer turntable drives the permanent magnet on the inner turntable to rotate. The rotation of the permanent magnet on the inner turntable drives the inner turntable to rotate, thus realizing contactless transmission. There is no contact between the outer turntable and the inner turntable. The transmission is carried out by magnetic force, so that the rotation of the outer turntable and the inner turntable will not affect the sealing between the inner shell and the outer shell, thereby improving the sealing performance of the valve. It is beneficial to avoid leakage caused by aging of sealing components when the valve is opened and closed by contactless transmission.

[0018] 2. The rotation of the inner turntable drives the first threaded rod to rotate. The rotation of the first threaded rod causes the sliding block to move towards the center of the horizontal tube. The movement of the sliding block towards the center of the horizontal tube causes the sealing gasket to move towards the center of the horizontal tube, sealing the horizontal tube. The two sealing gaskets move synchronously towards each other, providing a double seal for the horizontal tube. This ensures that when the valve is venting in either direction, one sealing gasket is always under pressure and sealed. Loosening the fasteners of the multi-angle installation mechanism and moving the horizontal tube left and right to the appropriate position, then tightening the fasteners, quickly fixes the horizontal tube. This facilitates left and right adjustment of the horizontal tube's installation position to adapt to different spatial installation requirements. Fixing the base plate of the up-down adjustment component in the appropriate position and rotating the second threaded rod causes the rotating rod to move up and down on the second threaded rod, allowing for quick adjustment of the support frame's up-down position. Simultaneously, the two support frames can be adjusted to different heights, allowing the equipment to adapt to installations at different heights and tilt angles. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] The present invention will be further described below with reference to embodiments.

[0031] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0032] Example 1: In some examples, please refer to Figures 1-7 A leak-proof hydrogen valve includes a horizontal pipe 1, and further includes: a multi-angle mounting mechanism 2, a bidirectional sealing mechanism 3, a contactless drive mechanism 4, and a synchronization mechanism 5. Two of the multi-angle mounting mechanisms 2 are installed on the left and right sides of the horizontal pipe 1, two of the bidirectional sealing mechanisms 3 are installed on the middle side of the horizontal pipe 1, the contactless drive mechanism 4 is mounted on the bidirectional sealing mechanism 3, and the synchronization mechanism 5 is mounted on the contactless drive mechanism 4. The contactless drive mechanism 4 includes: an inner shell 41, an inner rotating plate 42, an outer shell 43, an outer rotating plate 44, and... Permanent magnets 45 are provided. The inner shell 41 is fixedly installed on the outer shell 43. The inner turntable 42 is rotatably connected to the upper side of the inner shell 41 via a rotating shaft. The outer shell 43 is fixedly installed on the upper side of the inner shell 41. The outer turntable 44 is rotatably connected to the upper side of the outer shell 43 via a rotating shaft. Multiple permanent magnets 45 are fixedly installed on both the inner turntable 42 and the outer turntable 44. The permanent magnets 45 are arranged in a circular array on the inner turntable 42 and the outer turntable 44 with the center of the inner turntable 42 as the center. Adjacent permanent magnets 45 attract each other.

[0033] A sealing ring 46 is fixedly installed between the inner turntable 42 and the outer turntable 44. The sealing ring 46 is used to improve the sealing between the inner turntable 42 and the outer turntable 44. A rotating handle 47 is fixedly installed on the upper side of the rotating shaft of the outer turntable 44.

[0034] Rotating the handle 47 drives the outer turntable 44 of the contactless drive mechanism 4 to rotate. The rotation of the outer turntable 44 drives the permanent magnet on the outer turntable 44 to rotate. The rotation of the permanent magnet on the outer turntable 44 drives the permanent magnet on the inner turntable 42 to rotate. The rotation of the permanent magnet on the inner turntable 42 drives the inner turntable 42 to rotate, thus achieving contactless transmission. There is no contact between the outer turntable 44 and the inner turntable 42. The transmission is carried out by magnetic force, so that the rotation of the outer turntable 44 and the inner turntable 42 will not affect the sealing between the inner shell 41 and the outer shell 43, thereby improving the sealing performance of the valve. This is beneficial for preventing leakage caused by aging of sealing components when the valve is opened and closed through contactless transmission.

[0035] The bidirectional sealing mechanism 3 includes a sliding block 31, a sealing gasket 32, and a first threaded rod 33. The sliding block 31 is slidably connected to the middle side of the horizontal tube 1, and a groove is provided on the sliding block 31 so that the sliding block 31 will not rotate while sliding up and down on the horizontal tube 1. The sealing gasket 32 ​​is fixedly installed at one end of the sliding block 31 near the center of the horizontal tube 1. One end of the first threaded rod 33 is threadedly connected to the end of the sliding block 31 away from the center of the horizontal tube 1, and the other end of the first threaded rod 33 is fixedly connected to the rotating shaft of the inner turntable 42.

[0036] The rotation of the inner turntable 42 drives the first threaded rod 33 to rotate. The rotation of the first threaded rod 33 drives the sliding block 31 to move towards the center of the horizontal tube 1. The movement of the sliding block 31 towards the center of the horizontal tube 1 drives the sealing gasket 32 ​​to move towards the center of the horizontal tube 1. The movement of the sealing gasket 32 ​​towards the center of the horizontal tube 1 seals the horizontal tube 1. The two sealing gaskets 32 move synchronously towards each other, providing a double seal to the horizontal tube 1, so that when the valve is ventilated in any direction, one sealing gasket 32 ​​is always in a pressurized sealing state.

[0037] Example 2: In some embodiments, such as Figures 1-7 As shown, in a preferred embodiment of the present invention, the synchronization mechanism 5 includes: a driving bevel gear 51, an L-shaped bracket 52, and a driven bevel gear 53. The driving bevel gear 51 is fixedly mounted on the rotating shaft of the outer turntable 44. The driving bevel gear 51 is located between the outer turntable 44 and the rotating handle 47. The L-shaped bracket 52 is fixedly mounted on the outer shell 43. The two driven bevel gears 53 are rotatably connected to the L-shaped bracket 52, and the two driven bevel gears 53 are fixedly connected to the same rotating shaft. The rear driven bevel gear 53 meshes with the driving bevel gear 51.

[0038] Rotating the handle 47 causes the outer turntable 44 to rotate, which in turn causes the driving bevel gear 51 of the synchronizing mechanism 5 to rotate, and the driving bevel gear 51 in turn causes the driven bevel gear 53 on the rear side to rotate.

[0039] The synchronization mechanism 5 includes a transmission assembly mounted on an L-shaped bracket 52. The transmission assembly includes a connecting rod 54 and a transmission bevel gear 55. The connecting rod 54 is rotatably connected to two L-shaped brackets 52. The two transmission bevel gears 55 are fixedly mounted on the upper and lower ends of the connecting rod 54. The transmission bevel gears 55 and the front driven bevel gear 53 mesh with each other.

[0040] The rotation of the active bevel gear 51 drives the rotation of the rear driven bevel gear 53, which in turn drives the rotation of the front driven bevel gear 53. The rotation of the front driven bevel gear 53 drives the rotation of the transmission bevel gear 55. The rotation of the transmission bevel gear 55 activates another non-contact drive mechanism 4 and the bidirectional sealing mechanism 3, which facilitates the synchronous drive of the bidirectional sealing mechanism 3 to start bidirectional sealing.

[0041] Flanges 6 are fixedly installed on both the left and right sides of the horizontal pipe 1 for auxiliary connection to the pipeline.

[0042] The multi-angle mounting mechanism 2 includes: a collar 21, a support frame 22, and fasteners 23. The collar 21 is slidably connected to the horizontal tube 1, the support frame 22 is fixedly installed on the collar 21, and multiple fasteners 23 are threadedly connected to the collar 21. One end of each fastener 23 is in close contact with the outer wall of the horizontal tube 1, and the fastener 23 can be set as a screw.

[0043] Loosen the fasteners 23 of the multi-angle mounting mechanism 2, move the horizontal tube 1 left and right to the appropriate position, and tighten the fasteners 23 to quickly fix the horizontal tube 1. This allows for left and right adjustment of the installation position of the horizontal tube 1 to adapt to the installation needs of different spaces.

[0044] The multi-angle installation mechanism 2 further includes: a vertical adjustment assembly. Two vertical adjustment assemblies are installed on the front and rear sides of the support frame 22. The vertical adjustment assembly includes: a second threaded rod 24, a rotating rod 25, and a base plate 26. One end of the second threaded rod 24 is rotatably connected to the support frame 22. The rotating rod 25 is threadedly connected to the end of the second threaded rod 24 away from the support frame 22. The base plate 26 is hinged to the end of the rotating rod 25 away from the second threaded rod 24.

[0045] Fix the base plate 26 of the up-down adjustment assembly in a suitable position, rotate the second threaded rod 24, the rotation of the second threaded rod 24 causes the rotating rod 25 to move up and down on the second threaded rod 24, so that the up-down position of the support frame 22 can be quickly adjusted, and the two support frames 22 can be adjusted to different heights, so that the equipment can adapt to installation at different heights and different tilt angles.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
