Description

Technical Field

[0001] The invention relates to the technical field of pipeline valve components, in particular to a marine hydrogen power system pipeline component. Background Art

[0002] As a clean energy, hydrogen is gradually used in automobiles, ships and other drives. The valves of hydrogen-powered gas transmission pipelines are usually opened and closed electrically. After the pipeline valves are closed by electronic control, there is a risk of slow leakage due to poor closure due to the physical characteristics of the solenoid valve. Since hydrogen is flammable and explosive when it comes into contact with oxygen in the air, there is a high safety hazard when a trace leak occurs. Ordinary pressure and other detection sensors are not sensitive enough to trace hydrogen leaks and cannot achieve secondary closure. When impacted by a collision, there is a risk of rupture in the internal pipeline. At this time, if the pipeline valve is still in a ventilated state, it further increases the safety hazard, which can easily cause hydrogen leakage and cause a secondary accident.

[0035] The ejector trigger rod 517 is fixedly arranged directly below the plug disc support rod 513 . The ejector trigger rod 517 is fixedly mounted to the inner wall surface of the drainage cavity 510 through a brittle positioning rod 518 . An external mounting plate 519 is fixedly mounted on the lower end surface of the ejector trigger rod 517 .

[0036] A limiting blind tube 520 is fixedly installed on the surface of one side of the three-way end seat 505. One end of the limiting blind tube 520 is open and the other end is closed. An ejection closing column 521 is inserted into the inside of the limiting blind tube 520. An ejection compression spring 522 is arranged between the end of the ejection closing column 521 and the closed end of the limiting blind tube 520. A blind tube positioning hole 523 is penetrated and opened on the outer surface of the limiting blind tube 520. A positioning socket 524 is opened on the outer surface of the ejection closing column 521. One end of the locking plug-in 525 passes through the blind tube positioning hole 523 and is inserted into the inside of the positioning socket 524. A movable through groove 526 vertically passes through and is opened on the outer surface of the three-way end seat 505. The other end of the locking plug-in 525 passes through the movable through groove 526 and is fixedly installed on the outer surface of the plug support rod 513.

[0037] The end of the detection component tube 1 away from the connecting piston tube 2 is fixedly connected with an air outlet threaded tube 101, and a positioning bracket 102 is fixedly installed on the inner wall surface of the detection component tube 1. The plug plate plug rod 509 is inserted through the positioning bracket 102. A rolling sensor 103 is embedded and installed on the tube wall surface of the detection component tube 1. The rolling sensor 103 has a roller, and the roller is in contact with the plug plate plug rod 509. The displacement of the plug plate plug rod 509 can be used to drive the roller to roll. The rolling sensor 103 can detect the rolling of the roller. It is a common device in the prior art. The same principle is applied to mouse rollers, volume adjustment rollers, etc. , it will not be repeated in this application document. The rolling sensor 103 is in rolling contact with the outer surface of the plug disc rod 509. A guide slope 301 is provided on the surface of one end of the inner wall piston tube 3 close to the connecting piston tube 2. A sealing ring 302 is fixedly installed on the surface of one end of the inner wall piston tube 3 away from the connecting piston tube 2. A sealing rubber ring 303 is fixedly installed on the inner surface of the sealing ring 302. The sealing rubber ring 303 can be in contact and seal with the inner wall plug disc 4. A plug disc rubber ring 401 is installed on the outer sleeve of the inner wall plug disc 4. The outer surface of the plug disc rubber ring 401 can be in air-tight contact with the inner wall surface of the inner wall piston tube 3.

[0038] When the present invention is used, Figure 1 As shown in the figure, the connecting piston tube 2 is sealed and connected with the pipeline valve 7, the outlet threaded tube 101 is sealed and connected with the next level of the ship-borne hydrogen power system, and the external mounting plate 519 is extended to the outside. When an emergency occurs, the external mounting plate 519 is directly knocked or pressed to detect the vibration displacement deviation between the component tube 1 and the external mounting plate 519;

[0039] When the pipeline valve 7 is normally opened for ventilation, high-pressure hydrogen enters the connecting piston tube 2, and the driving piston disc 5 is quickly pushed backward. A small amount of gas passes through the ventilation micropores 6 and does not affect the movement of the driving piston disc 5. At this time, the holding return spring 504 is compressed, driving the telescopic inner rod 501 to move inside the hydraulic driving outer cylinder 502, and pressing the liquid in the hydraulic driving outer cylinder 502 into the hydraulic connecting pipe 506. Since the other end of the hydraulic connecting pipe 506 is connected to the driven hydraulic cylinder 507, it can drive the plug disc plug rod 509 to extend, and the inner wall plug disc 4 is pushed out and separated from the inner wall piston tube 3. Figure 3 As shown in , here, according to Pascal's principle, the area ratio of the large and small pistons is the same as the pressure ratio. Since the diameter of the driving telescopic inner rod 501 is smaller than the diameter of the plug disc plug rod 509, the area where the driving telescopic inner rod 501 applies thrust to the liquid is smaller, and the plug disc plug rod 509 has a larger force-bearing area. Therefore, the driving telescopic inner rod 501 can use a smaller force to push the plug disc plug rod 509 to move with a larger force, and the displacement distance of the driving telescopic inner rod 501 is also relatively longer. At this time, the assembly of the present invention is Figure 2In the state shown in FIG. 1 , the gas can freely pass through the detection assembly tube 1 and reach the next stage of the shipboard hydrogen power system from the outlet threaded tube 101 ;

[0040] After the pipeline valve 7 is closed, the driving piston disc 5 loses the gas thrust and gradually moves toward the direction of the pipeline valve 7 under the reset elasticity of the holding reset spring 504. The residual gas in the connecting piston tube 2 is discharged through the ventilation micropores 6 to prevent the air pressure from affecting the movement of the driving piston disc 5. At this time, the telescopic inner rod 501 is driven to move outside the hydraulic driving outer cylinder 502, and the hydraulic connecting pipe 506 sucks out the liquid from the driven hydraulic cylinder 507, causing the plug disc plug rod 509 to contract. When the inner wall plug disc 4 is in sealing contact with the inner wall piston tube 3, Since the inner wall plug disc 4 completely blocks the connecting piston tube 2, a sealed cavity is formed on the side of the inner wall plug disc 4 close to the connecting piston tube 2, and the negative pressure in the cavity is used to prevent the inner wall plug disc 4 from continuing to move into the inner wall piston tube 3. After the inner wall plug disc 4 is prevented from moving, the counter force transmitted by the hydraulic linkage structure keeps the driving piston disc 5 fixed. The rolling sensor 103 records the moving trajectory of the plug disc plug rod 509 through the roller. In this stable state, the component of the present invention detects and monitors the sealing condition of the pipeline valve 7;

[0041] When a small amount of leakage occurs in the pipeline valve 7, the small amount of leaked hydrogen cannot drive the piston disc 5 to move. The connection of the vent micropores 6 is enough to allow a small amount of hydrogen to pass through, and a small amount of hydrogen enters the connecting piston tube 2, causing the pressure in the sealed cavity formed by the inner wall plug disc 4 close to the side where the connecting piston tube 2 is located to increase. As the pressure increases, the inner wall plug disc 4 is pushed to move away from the connecting piston tube 2. At this time, the plug disc plug rod 509 is driven synchronously, and the rolling sensor 103 contacts the plug disc plug rod 509 through the roller, thereby detecting the movement amplitude and speed of the plug disc plug rod 509, and then knowing the leakage of the pipeline valve 7, and issuing an alarm. When the inner wall plug disc 4 reaches the position of the sealing plug ring 302, the inner wall plug disc 4 contacts the sealing rubber ring 303 to form a seal, thereby temporarily closing the pipeline valve 7 for a second time.

[0042] When an emergency occurs and the pipeline valve 7 is still open, there is a vibration displacement deviation between the detection component pipe 1 and the external mounting plate 519 due to the different fixing stability. The deviation caused by the above displacement causes the external mounting plate 519 to drive the ejector trigger rod 517 and the plug disc support rod 513 to move relative to each other. The brittle positioning rod 518 is made of a brittle material, which can fix the ejector trigger rod 517 under normal conditions, but will break in the event of a collision, releasing the fixation of the ejector trigger rod 517. Since the ejector trigger rod 517 and the plug disc support rod 513 directly move relative to each other, the plug disc support rod 513 loses the ejector trigger rod 517. 7, under the action of the compression spring 516, drives the normally closed sealing plug 511 to move downward, so that the liquid in the hydraulic connecting pipe 506 is discharged through the drain cavity 510. After the hydraulic connecting pipe 506 loses the hydraulic liquid, the inner wall plug disc 4 can move freely axially. At the same time, the downward movement of the plug disc support rod 513 will drive the locking plug 525 to move downward. After the ejection sealing column 521 loses its fixation, it extends out under the action of the ejection compression spring 522, pushing the inner wall plug disc 4 toward the inner wall piston tube 3, and under the pressure of the gas ejected from the pipeline valve 7, the inner wall plug disc 4 will quickly move toward the sealing plug ring 302, thereby forming an emergency closure to prevent hydrogen leakage.
