Description

TECHNICAL FIELD

[0001] The application relates to the technical field of oxygen-doped pressure regulators, in particular to a high-stability hydrogen-doped pressure regulator and an implementation method thereof. BACKGROUND

[0002] The high-stability hydrogen-doped pressure regulator is a key device used in a hydrogen and other gas mixing system, and mainly functions to accurately control the pressure and proportion of mixed gas, so that the output hydrogen-doped gas has high stability, thereby meeting the safe and efficient use requirements.

[0003] In the hydrogen delivery link of the traditional hydrogen-doped pressure regulator, a simple pipeline access mode is mostly used, and hydrogen flows into the mixing area in a straight line. This mode is prone to cause uneven distribution of hydrogen in the mixed gas, cannot meet the application scenarios with high requirements on the quality and stability of mixed gas, and affects the hydrogen-doping effect. Meanwhile, the existing hydrogen-doped pressure regulator lacks a speed reducer inside when delivering hydrogen. When delivering high-pressure hydrogen, if the high-pressure hydrogen is not reduced in speed and pressure, the high-pressure hydrogen will directly impact the inner wall of the container due to the high flow rate and kinetic energy of the high-pressure hydrogen. The high flow rate and large kinetic energy will cause the pipeline to be severely worn and reduce the service life of the pipeline, and even may cause serious safety accidents such as rupture of the mixing container and hydrogen leakage. When stopping the delivery of hydrogen, the existing hydrogen-doped pressure regulator usually adopts the mode of directly closing the main pipeline valve. This mode will make the hydrogen in the pipeline lose the flow channel instantaneously, cause the pressure to sharply rise in a very short time, form a water hammer effect, and then cause serious damage to the pipeline, valve and related connecting parts, shorten the service life of the equipment, and also bring safety hazards.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0035] Embodiment one: refer to Figures 1-11 A high-stability hydrogen-doped pressure regulator, comprising a main body 1, the inside of the main body 1 is respectively provided with a left gas tank 2, a hydrogen tank 5 and a mixing tank 47, a gas guide pipe 6 is arranged in communication between the hydrogen tank 5 and the mixing tank 47, one end of the gas guide pipe 6 located in the inside of the mixing tank 47 is arranged in communication with a pressure regulating pipe 8, and an opening and closing speed reducing mechanism is arranged in the inside of the pressure regulating pipe 8.

[0036] The opening and closing speed reducing mechanism comprises a rotating cylinder 23 rotatably connected to the end of the pressure regulating pipe 8, a pull rod 25 slidably penetrating through the inside of the rotating cylinder 23, a closing plate 28 fixedly connected to one end of the pull rod 25 located in the inside of the rotating cylinder 23, a pull spring 24 sleeved with one end of the pull rod 25 located outside the rotating cylinder 23, a connecting rod 26 fixedly connected to both sides of the pull rod 25, a roller rotatably connected to the end of the connecting rod 26, a sliding rail 27 fixedly connected to both sides of the rotating cylinder 23, a horizontal moving piece 30 slidably connected to the inside of the sliding rail 27, a pressing spring 29 fixedly connected to the outer side wall of the horizontal moving piece 30, and one end of the pressing spring 29 away from the horizontal moving piece 30 is fixedly connected to the inner side wall of the sliding rail 27.

[0037] The outer side wall of the horizontal moving piece 30 is fixedly connected with an outer pushing piece 48, the outer pushing piece 48 is provided with a median plane 33 and a top plane 34, the inside of the sliding rail 27 is slidably penetrated through a limiting piece 31, one end of the limiting piece 31 located in the inside of the sliding rail 27 is sleeved with a pressure spring 32, a plurality of spray pipes 37 are arranged in communication on the rotating cylinder 23, a sleeve ring 38 is slidably connected to the outer side wall of each of the plurality of spray pipes 37, a horizontal moving rod 35 is fixedly connected to the outer side wall of the sleeve ring 38, one end of the horizontal moving rod 35 away from the sleeve ring 38 is slidably penetrated into the inside of the rotating cylinder 23, and a trigger magnet is fixedly connected to one end of the horizontal moving rod 35 away from the sleeve ring 38.

[0038] Both sides of the end of the spray pipe 37 are fixedly connected with a mounting plate 40, the mounting plate 40 and the sleeve ring 38 are fixedly connected with a return spring 39, the end of the spray pipe 37 is fixedly connected with a mounting frame 43, the inside of the mounting frame 43 is rotatably connected with a rotating plate 44, a plurality of special-shaped holes 46 are formed in the rotating plate 44, both sides of the rotating plate 44 are fixedly connected with a gear 45, both sides of the sleeve ring 38 are fixedly connected with a pushing plate 41, and the end of the pushing plate 41 is provided with a rack 42, the rack 42 and the gear 45 are in meshing arrangement.

[0039] The inside of the pressure regulating pipe 8 is fixedly connected with a mounting bracket 9, the outer side wall of the mounting bracket 9 is fixedly connected with a driving motor 11, the output end of the driving motor 11 is provided with a transmission rod 10, the end of the transmission rod 10 is fixedly connected with a fixed plate, the fixed plate is fixedly connected with the rotating cylinder 23, the outer side wall of the pressure regulating pipe 8 is fixedly connected with a gas tank 12, and the inside of the gas tank 12 is provided with a gas guide mechanism.

[0040] In this embodiment, before use, the gas in the left gas tank 2 can be input into the mixing tank 47 through the gas inlet pipe 4, which facilitates the subsequent mixing of hydrogen. During use, when hydrogen needs to be added to the mixing tank 47, the operator can open the valve in the hydrogen tank 5 and add hydrogen to the mixing tank 47 through the gas inlet pipe 6. When the gas inlet pipe 6 delivers hydrogen to the pressure regulating pipe 8, the operator can open the drive motor 11 to drive the transmission rod 10 to rotate. When the transmission rod 10 rotates, it drives the rotating drum 23 to rotate synchronously. When the rotating drum 23 rotates, the horizontal moving piece 30 overcomes the elastic force of the pressing spring 29 and drives the outer pushing piece 48 to move outward along the slide rail 27 under the action of the centrifugal force generated by rotation. When the outer pushing piece 48 moves outward, the roller at the bottom of the connecting rod 26 first contacts the inclined surface of the outer pushing piece 48, thereby reaching the middle plane 33. When the roller at the bottom of the connecting rod 26 contacts the middle plane 33, it pushes the pull rod 25 outward along the rotating drum 23. When the horizontal moving piece 30 drives the outer pushing piece 48 to move away from the limiting piece 31, the horizontal moving piece 30 no longer contacts the limiting piece 31. When the limiting piece 31 loses the pressing force of the horizontal moving piece 30, it retracts to the inner wall of the rotating drum 23 under the elastic force of the pressure spring 32, thereby no longer blocking the movement of the closing plate 28. When the limiting piece 31 no longer blocks the movement of the closing plate 28, the closing plate 28 moves towards the horizontal moving rod 35 under the pulling of the pull rod 25, reaching above the open ends of the plurality of spray pipes 37 (see Figure 8 ). When the closing plate 28 no longer blocks the open ends of the plurality of spray pipes 37, the hydrogen inside the rotating drum 23 enters the spray pipes 37 through the open ends, and then is delivered into the mixing tank 47 through the spray pipes 37 for hydrogen mixing. Since the rotating drum 23 rotates when hydrogen is mixed through the plurality of spray pipes 37, the hydrogen can be mixed with the gas discharged from the left gas tank 2 in the mixing tank 47 in multiple directions.

[0041] Embodiment Two: Figures 1-11 The gas guide mechanism includes a gas guide box 20 connected in communication inside the gas tank 12. The gas guide box 20 has a sliding plate 21 slidably connected inside. The sliding plate 21 has a flow-through hole 22.

[0042] The drive motor 11 has a top bracket 13 fixedly connected to the outer side wall. The top bracket 13 has a closing switch 18 and a high-power switch 19 fixedly connected to the outer side wall. The top bracket 13 has a sliding groove 14 inside. The sliding groove 14 has a wind deflector 16 slidably connected inside. The sliding groove 14 has a return spring 15 fixedly connected inside. The other end of the return spring 15 is fixedly connected to the outer side wall of the wind deflector 16. The end of the wind deflector 16 is fixedly connected to the sliding plate 21. The end of the wind deflector 16 away from the sliding plate 21 is fixedly connected to a contact piece 17.

[0043] A gas conveying pipe 4 is arranged in communication between the left gas tank 2 and the mixing tank 47, a flange connector 7 is arranged in communication on the mixing tank 47, and a gas filling port 3 is arranged on the left gas tank 2 and the hydrogen tank 5.

[0044] A plurality of bottom magnets 36 are fixedly connected to the outer side wall of the closing plate 28, and the magnetic poles of the bottom magnets 36 are the same as those of the trigger magnets.

[0045] In the embodiment, when the gas guide pipe 6 delivers high-pressure hydrogen into the pressure regulating pipe 8, the high-pressure hydrogen entering the pressure regulating pipe 8 will blow the impact wind guide plate 16, so that the wind guide plate 16 overcomes the elastic force of the return spring 15 and drives the contact piece 17 to move towards the top support 13 until the contact piece 17 contacts the high-power switch 19. When the contact piece 17 contacts the high-power switch 19, the driving motor 11 will drive the transmission rod 10 to rotate rapidly at high power (which is prior art and will not be described in detail). When the transmission rod 10 rotates rapidly, it will drive the rotating drum 23 to rotate rapidly. Under the action of the centrifugal force generated by the rapid rotation, the horizontal moving piece 30 will drive the outer pushing piece 48 to move a relatively large distance away from the pressure spring 32 by overcoming the elastic force of the pressing spring 29. Correspondingly, the outer pushing piece 48 moving a long distance will make the two contact inclined surfaces contact the rollers at the bottom of the connecting rod 26 in sequence, and finally make the rollers contact the top plane 34. When the connecting rod 26 contacts the top plane 34, it will push the pull rod 25 to move a relatively large distance away from the rotating drum 23. According to the above principle, when the pull rod 25 moves a large distance, it will drive the closing plate 28 to move synchronously. When the closing plate 28 moves a large distance upwards, it will be located at a position relatively far above the spray pipe 37 (refer to Figure 8 When the horizontal moving rod 35 moves towards the outside of the rotating drum 23, it will overcome the elastic force of the return spring 39 and push the sleeve ring 38 and the pushing plate 41 to move towards the mounting frame 43. When the pushing plate 41 moves outward, it will make the gear 45 rotate through the rack 42, thereby driving the rotating plate 44 to flip. When the rotating plate 44 flips, it will block the end of the spray pipe 37. According to the above principle, when the rotating drum 23 delivers high-pressure hydrogen outward through the spray pipes 37, the high-pressure hydrogen delivered through the spray pipes 37 will impact the rotating plate 44. When the high-pressure hydrogen impacts the rotating plate 44, it will pass through the special-shaped hole 46. Since the inside of the special-shaped hole 46 is relatively tortuous, the high-pressure hydrogen entering the special-shaped hole 46 will generate viscous friction with the inner wall of the special-shaped hole 46, thereby reducing the speed of the high-pressure hydrogen and avoiding the high-pressure hydrogen impacting the inner wall of the mixing tank 47 at a high speed, thereby reducing the wear of the mixing tank 47.

[0046] When the gas guide pipe 6 delivers high-pressure hydrogen into the pressure regulating pipe 8, if the high-pressure hydrogen is faster and has a greater pressure than before, reaching the bearing threshold of the mixing tank 47, at this time the ultrahigh-pressure hydrogen will impact the air deflector 16, causing the air deflector 16 to drive the contact 17 to the upper side of the closed switch 18 and touch it, when the contact 17 touches the closed switch 18, it will cause the driving motor 11 to be closed (this is prior art, and will not be described in detail), when the driving motor 11 is closed and no longer drives the transmission rod 10 to rotate, at this time the rotating drum 23 will stop rotating, and the centrifugal force disappears, at this time the horizontal moving piece 30 will return to the original position under the elastic force of the pressing spring 29, when the horizontal moving piece 30 returns to the original position, the outer pushing piece 48 will no longer contact the bottom roller of the connecting rod 26, at this time the pull rod 25 will drive the closing plate 28 to return to the original position under the pulling force of the tension spring 24, and the closing plate 28 is located below the opening end of the jet pipe 37, blocking the hydrogen and preventing the hydrogen from being delivered through the jet pipe 37, when the horizontal moving piece 30 returns to the original position, it will also contact the limiting piece 31, allowing the limiting piece 31 to block and limit the closing plate 28 again, so that the closing plate 28 blocks the hydrogen and prevents the rotating drum 23 from mixing hydrogen into the mixing tank 47, when the air deflector 16 drives the contact 17 to move and touch the closed switch 18, it will also drive the sliding plate 21 to move synchronously, allowing the flow-through hole 22 to enter the gas guide box 20, at this time the ultrahigh-pressure hydrogen delivered by the pressure regulating pipe 8 will enter the gas tank 12 through the gas guide box 20 and the flow-through hole 22, and the pressure in the pressure regulating pipe 8 will be released, preventing the hydrogen from losing the flow path and causing the pressure in the pressure regulating pipe 8 to rise and forming a water hammer phenomenon.

[0047] An implementation method of a high-stability hydrogen mixing pressure regulator, the implementation method comprising the following steps:

[0048] S1: When hydrogen needs to be mixed into the mixing tank 47, the operator opens the valve in the hydrogen tank 5 to mix hydrogen into the mixing tank 47 through the gas guide pipe 6;

[0049] S2: When the gas guide pipe 6 mixes hydrogen into the mixing tank 47, the opening and closing speed reduction mechanism will rotate and deliver the hydrogen, facilitating the mixing of hydrogen in the mixing tank 47;

[0050] S3: When the gas guide pipe 6 mixes high-pressure hydrogen into the mixing tank 47, the opening and closing speed reduction mechanism will reduce the speed and pressure of the high-pressure hydrogen;

[0051] S4: When the delivered high-pressure hydrogen exceeds the bearing threshold of the mixing tank 47, the opening and closing speed reduction mechanism will stop the delivery of hydrogen and release the pressure in the pressure regulating pipe 8.

[0052] It should be noted that when the low-pressure hydrogen gas is delivered in the pressure regulating tube 8, the low-pressure hydrogen gas will not push the air deflector 16 to move because the speed of the low-pressure hydrogen gas is slow. Meanwhile, the one-way valve is arranged in the air tank 12, so the pressure relief hydrogen gas entering the air tank 12 will not flow back through the air guide box 20.

[0053] It should be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another, without necessarily requiring or implying any actual relationship or order between such entities or actions.

The high-stability hydrogen-doped pressure regulator according to claim 1, characterized in that: The outer side wall of the closing plate (28) is fixedly connected with a plurality of bottom magnets (36), and the magnetic poles of the bottom magnets (36) are the same as those of the trigger magnets.

5. The implementation method of the high-stability hydrogen-doped pressure regulator, using the high-stability hydrogen-doped pressure regulator of any one of claims 1-4, characterized in that: The implementation method comprises the following steps: S1: When hydrogen needs to be added into the mixing tank (47), the operator opens the valve in the hydrogen tank (5) to add hydrogen into the mixing tank (47) through the gas guide pipe (6); S2: When the gas guide pipe (6) adds hydrogen into the mixing tank (47), the opening and closing speed reduction mechanism rotates the hydrogen to facilitate the mixing of the hydrogen in the mixing tank (47); S3: When the gas guide pipe (6) adds high-pressure hydrogen into the mixing tank (47), the opening and closing speed reduction mechanism reduces the speed and pressure of the high-pressure hydrogen; S4: When the delivered high-pressure hydrogen exceeds the bearing threshold of the mixing tank (47), the opening and closing speed reduction mechanism stops the delivery of hydrogen and simultaneously releases the pressure in the pressure regulating pipe (8).
