Abstract

The present invention discloses a modular integrated hydrogenation bottle valve, which relates to the field of hydrogen bottle valves, and comprises a valve body, wherein the outer wall of the valve body is fixedly connected with a rotating mechanism, the inner side of the valve body is fixedly connected with a first alarm mechanism, and the inner side of the valve body is fixedly connected with a second alarm mechanism. The present invention sets the first alarm mechanism and the second alarm mechanism. During hydrogenation, when a valve core in the valve is blocked, the rotating mechanism drives the hydrogen to remain in the valve body. When there is too much hydrogen in the valve body, the first alarm or the second alarm sounds an alarm to remind the staff to stop hydrogenation in time and replace the valve, thereby improving the safety during the hydrogenation process. By setting a collecting mechanism, when the valve is blocked, the collecting mechanism can collect the hydrogen that still enters the valve body before the staff finds it, thereby preventing the hydrogen from entering the valve and not being discharged, causing the hydrogen inside the valve to increase and the air pressure to increase, thereby causing the valve to burst. At the same time, the hydrogen is collected in a concentrated manner when the valve is blocked.

Description

Technical Field

[0001] The invention relates to the field of hydrogen bottle valves, and in particular to a modular integrated hydrogenation bottle valve. Background Art

[0002] The high-pressure hydrogen integrated bottle valve for fuel cell vehicles (hereinafter referred to as the "hydrogen bottle valve") is installed on the hydrogen storage bottle of the fuel cell vehicle to control the opening and closing of the hydrogen in the hydrogen storage bottle. Hydrogen is a flammable and dangerous gas. Its storage, transportation and use safety are very important. Therefore, the hydrogen bottle valve is classified as a gas cylinder safety accessory and is a special equipment. In relevant laws and regulations and standards, the gas cylinder must be bound to the vehicle and cannot be replaced at will.

[0003] The hydrogenation bottle valve refers to the valve that controls the flow of hydrogen in the hydrogenation bottle. Currently, flap-type bottle valves are mostly used. This valve is easy to use and can be opened directly with a wrench. When in use, the valve core is controlled to rotate counterclockwise to open and clockwise to close.

[0004] However, during hydrogen refueling, the current valves have a single structure and only a single layer, which leads to problems such as insufficient explosion-proof capability, easy leakage, and insufficient pressure resistance. The valve core often rotates to control the valve switch, and the valve core is prone to wear and looseness, resulting in malfunctions, causing the valve core to get stuck or blocked. When blockage occurs, hydrogen cannot be discharged from the valve normally, resulting in excessive hydrogen in the valve. The valve is prone to bursting, causing hydrogen leakage, causing danger. At the same time, the sealing of the connection between the valve and the hydrogen cylinder pipe is poor, which is also prone to hydrogen leakage during refueling. Summary of the invention

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The following describes an embodiment of the present invention based on its overall structure.

[0038] A modular integrated hydrogenation bottle valve, as shown in the figure, includes a valve body 100, the outer wall of the valve body 100 is fixedly connected to a rotating mechanism 200, the inner side of the valve body 100 is fixedly connected to a first alarm mechanism 300, the inner side of the valve body 100 is fixedly connected to a second alarm mechanism 400, and one side of the valve body 100 is fixedly connected to a collecting mechanism 500; the rotating mechanism 200 includes a first connecting pipe 210 fixedly connected to the outer wall of the valve body 100, the inner wall of the valve body 100 is rotatably connected to a first rotating shaft 220, the outer wall of the first rotating shaft 220 is fixedly connected to a rotating assembly 240, the outer wall of the first rotating shaft 220 is located in the inner part of the first connecting pipe 210, and the outer wall is fixedly connected to a rotating leaf 230, the inner wall of the first connecting pipe 210 is connected to an L-shaped pipe 260, the L-shaped pipe 260 is connected to the inside of the first connecting pipe 210, and the inner wall of the valve body 100 is connected to the second connecting pipe 210. The connecting pipe 250, the interior of the first connecting pipe 210 is connected to the valve pipe 600, and the inner side of the valve pipe 600 is fixedly connected to the connecting mechanism 700; the rotating assembly 240 includes a first gear 241 fixedly connected to the outer wall of the first rotating shaft 220, the first gear 241 is meshed with the second gear 242, the inner wall of the second gear 242 is fixedly connected to the second rotating shaft 243, one end of the second rotating shaft 243 is fixedly connected to the fan 244, the second rotating shaft 243 is rotatably connected to the valve body 100, and the fan 244 is located inside the second connecting pipe 250; a plurality of rotating blades 230 are provided, and the plurality of rotating blades 230 are arranged in a circular array with the first rotating shaft 220 as the axis, the inner wall of the valve pipe 600 is rotatably connected to the valve switch 800, the valve pipe 600, the connecting mechanism 700 and the valve switch 800 are each provided with two groups, and the second connecting pipe 250 is connected to the valve pipe 600.

[0039] The valve tube 600 is connected to the pipeline on the hydrogen cylinder through a flange, and the connecting mechanism 700 seals the valve tube 600 and the connected pipeline, so that the overall sealing of the bottle valve is better. The valve switch 800 is turned, and hydrogen flows in the two groups of valve tubes 600. When the front group of valve tubes 600 or the pipeline connected thereto in the flow direction of the airflow is blocked, the rotating mechanism 200 guides the flow of hydrogen to trigger the alarm in the first alarm mechanism 300 to remind the staff of the blockage. When the rear group of valve tubes 600 or the pipeline connected thereto is blocked, the second alarm mechanism 400 is triggered to sound an alarm to remind the staff of the blockage. The staff can quickly know the blockage location for subsequent processing. At the same time, the collecting mechanism 500 can collect hydrogen when it is blocked to prevent the valve from bursting and hydrogen leakage due to excessive air pressure in the valve tube 600 or the valve body 100, thereby causing safety accidents, thereby improving safety.

[0040] Specifically, hydrogen enters the first connecting pipe 210 through the previous group of valve pipes 600, and the airflow of the hydrogen flow drives the rotating blades 230 to rotate around the first rotating shaft 220 as the axis, thereby driving the first rotating shaft 220 to rotate, and then driving the first gear 241 to rotate. The rotation of the first gear 241 drives the second gear 242 to rotate around the second rotating shaft 243 as the axis, thereby driving the fan 244 to rotate around the second rotating shaft 243 as the axis, and then driving the hydrogen in the valve pipe 600 that enters the valve body 100 through the L-shaped pipe 260 to flow into the second connecting pipe 250 to the group of valve pipes 600 connected to the second connecting pipe 250, and the hydrogen is then discharged from the valve through this group of valve pipes 600.

[0041] Please refer to Figure 3 and Figure 6The first alarm mechanism 300 includes a fixing bar 310 fixedly connected to the inner side of the valve body 100, a fixing shaft 320 is fixedly connected to the bottom end of the fixing bar 310, a rotating plate 330 is rotatably connected to the outer wall of the fixing shaft 320, a limiting bar 340 located on one side of the rotating plate 330 is fixedly connected to the bottom end of the fixing bar 310, a connecting rod 350 is fixedly connected to one side of the limiting bar 340, and an alarm assembly 360 is fixedly connected to the inner wall of the valve body 100, and the fixing bar 310, the fixing shaft 320, the rotating plate 330, the limiting bar 340 and the connecting rod 350 are all provided in two groups; the alarm assembly 360 includes a fixing bar 310 fixedly connected to the inner wall of the valve body 100, and a fixing bar 310, a fixing shaft 320, a rotating plate 330, a limiting bar 340 and a .... An alarm box 361 is fixedly connected, a moving block 362 is slidably connected to the inner wall of the alarm box 361, a first switch 363 is fixedly connected to the inner side of the alarm box 361, a first alarm 364 is fixedly connected to the outer side of the alarm box 361, the first switch 363 and the first alarm 364 are electrically connected, one end of the moving block 362 is fixedly connected to a first spring 365, one end of the first spring 365 is fixedly connected to the inner side of the alarm box 361, two groups of first springs 365 are provided, and the two groups of first springs 365 are symmetrically arranged on both sides of the first switch 363, and the connecting rod 350 is abutted against the moving block 362.

[0042] When the valve core located at the left half of the first connecting tube 210 in the hydrogen bottle valve is blocked, no hydrogen enters the valve tube 600 on the left side of the first connecting tube 210, and there is no airflow to drive the rotating blade 230 to rotate, so that the first rotating shaft 220 cannot rotate, and further cannot drive the fan 244 to rotate. Since the connection port of the L-shaped tube 260 connecting the valve tube 600 is located in front of the valve core, the hydrogen that cannot pass through the valve core can enter the valve body 100 through the L-shaped tube 260. Since the hydrogen cannot enter the valve tube 600 through the valve core, more hydrogen enters the valve body 100 through the L-shaped tube 260. Since the fan 244 no longer rotates by itself under the drive of the rotating blade 230 at this time, the speed of the airflow entering the latter group of valve tubes 600 through the second connecting tube 250 becomes slower. At this time, the hydrogen in the valve body 100 becomes more. , which increases the air pressure in the valve body 100. At the same time, the air flow outlet on the L-shaped tube 260 faces the fitting part of the two sets of rotating plates 330, thereby pushing the rotating plates 330 to rotate around the fixed shaft 320. The rotating plates 330 that were originally fitted are separated, and at the same time, the connecting rod 350 is driven to move, thereby pushing the moving block 362 to slide in the alarm box 361 and touch the first switch 363. The first spring 365 is compressed, thereby driving the first alarm 364 to sound an alarm to remind the staff that the valve is blocked. A switch valve is provided in the L-shaped tube 260. When the valve is not in use, the switch valve in the L-shaped tube 260 is closed, and the gas cannot enter the valve body 100 through the L-shaped tube 260. When the valve is used, the valve core in the valve body 100 and the switch valve in the L-shaped tube 260 are opened at the same time, and hydrogen can pass normally.

[0043] Please refer to Figure 3 and Figure 4 The second alarm mechanism 400 includes a third connecting tube 410 connected to the inside of the valve body 100, and the inner side of the valve body 100 is fixedly connected to a limiting frame 440 above the third connecting tube 410, and the inner wall of the limiting frame 440 is slidably connected to a push rod 430, and the bottom end of the push rod 430 is fixedly connected to a push plate 420, and the push plate 420 is slidably connected to the limiting frame 440, and the push plate 420 is slidably connected to the third connecting tube 410, and the top of the push plate 420 is fixedly connected to a second spring 450, and the second spring 450 is fixedly connected to the limiting frame 440; the inner side of the valve body 100 is fixedly connected to a second switch 460, and the outer wall of the valve body 100 is fixedly connected to a second alarm 470, and the second switch 460 and the second alarm 470 are electrically connected.

[0044] When the valve core located at the right part of the first connecting tube 210 in the hydrogen bottle valve is blocked, hydrogen cannot flow out of the valve through the rear half, but at the same time, hydrogen continues to enter the rear group of valve tubes 600. At this time, the hydrogen in the rear group of valve tubes 600 increases, and the increased air pressure drives the push plate 420 to move upward along the inner wall of the third connecting tube 410, thereby driving the push rod 430 to move upward to the inside of the limit frame 440. At this time, the hydrogen in the valve tube 600 enters the valve body 100 through the third connecting tube 410, and the push rod 430 moves upward, driving the second spring 450 to be stretched, and at the same time, the top of the push rod 430 touches the second switch 460, thereby driving the second alarm 470 to sound an alarm, reminding the staff that the valve is leaking. When the blockage is unblocked, the air pressure is normal, the force pushing the push plate 420 to move upward disappears, and the second spring 450 is reset, driving the push plate 420 to move and reset to the inside of the third connecting tube 410. At this time, the hydrogen flows normally from the valve pipe 600 and does not enter the valve body 100 through the third connecting pipe 410 .

[0045] Please refer to Figure 5 The collecting mechanism 500 includes an air collecting box 510 fixedly connected to the outer wall of the valve body 100, a piston block 520 is slidably connected to the inner side of the air collecting box 510, an air guide pipe 530 is fixedly connected to the inner wall of the air collecting box 510, a first one-way valve 540 is fixedly connected to the inner side of the air guide pipe 530, an exhaust pipe 550 is fixedly connected to the inner wall of the air collecting box 510, a second one-way valve 560 is fixedly connected to the inner side of the exhaust pipe 550, a sealing cover 570 is provided on the outer wall of the exhaust pipe 550, and the air guide pipe 530 is connected to the inside of the valve body 100.

[0046] When the valve is clogged, hydrogen cannot be discharged from the valve normally, resulting in excessive hydrogen in the valve. When excessive hydrogen enters the valve body 100, the hydrogen will enter the gas collecting box 510 through the air guide pipe 530, thereby driving the piston block 520 to move upward along the inner wall of the gas collecting box 510. When an alarm occurs, the hydrogen enters the gas collecting box 510 for collection, so that the hydrogen in the valve pipe 600 and the valve body 100 will not burst and leak due to excessive air pressure, causing a safety accident. At the same time, when there is too much hydrogen in the gas collecting box 510, it can be discharged through the gas guide pipe 530. The hydrogen in the gas collecting box 510 is centrally processed through the exhaust pipe 550, and the piston block 520 is pressed into the gas collecting box 510 to drive the hydrogen in the gas collecting box 510 to be discharged from the exhaust pipe 550. Before collection, the sealing cover 570 is removed from the exhaust pipe 550, and the collection tank is connected to the exhaust pipe 550 to collect the hydrogen. Due to the characteristics of the one-way valve, the second one-way valve 560 allows hydrogen to pass from the gas collecting box 510 to the outside of the exhaust pipe 550, and the first one-way valve 540 allows hydrogen to pass from the air guide pipe 530 to the gas collecting box 510.

[0047] Please refer to Figure 7 The connecting mechanism 700 includes an inner ring 710 fixedly connected to the inner side of the valve tube 600, an annular groove 720 is provided on the inner ring 710, a first pressing groove 740 is provided on the inner ring 710, the first pressing groove 740 is communicated with the annular groove 720, a hollow rubber strip 730 is fixedly connected in the groove of the annular groove 720, a second pressing groove 780 is provided on the valve tube 600, a pressing block 760 is slidably connected in the groove of the second pressing groove 780, a third spring 750 is fixedly connected in the groove of the second pressing groove 780, the third spring 750 is fixedly connected to the pressing block 760, and an annular plate 770 is fixedly connected to one end of the pressing block 760; the first pressing groove 740, the third spring 750 and the pressing block 760 are all provided in multiple groups, and the multiple groups of the first pressing groove 740, the third spring 750 and the pressing block 760 are arranged in a circular array with the valve tube 600 as the axis.

[0048] Before hydrogenation, the valve needs to be installed on the hydrogen cylinder. When connected through the flange, the valve tube 600 drives the inner ring 710 to insert into the inner side of the connecting pipe on the hydrogen cylinder and fit with the inner side. When the connecting pipe is close to the valve tube 600, the annular plate 770 is pushed to move in the direction of the pressure block 760, driving the pressure block 760 to move in the second pressure groove 780. Similar to the hydraulic jack, the hydraulic oil in the third spring 750 is driven to enter the first pressure groove 740 and then enter the hollow rubber strip 730. Since the hollow rubber strip 730 is made of elastic material, the hydraulic oil in the hollow rubber strip 730 increases, and the hollow rubber strip 730 is stretched open to fit with the annular groove 720 and fit with the inner wall of the pipeline and the valve tube 600 at the same time. The connection between the valve tube 600 and the pipeline is blocked from the inside and sealed to prevent hydrogen leakage. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
