Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen energy valves, in particular to a hydrogen energy valve which prevents hydrogen leakage. Background Art

[0002] With the rapid development of hydrogen energy technology, hydrogen energy valves, as an indispensable part of hydrogen energy systems, are receiving more and more attention for their safety and reliability. Traditional hydrogen energy valves are prone to hydrogen leakage when used for a long time or operated improperly, which not only causes energy waste, but also may cause serious safety accidents.

[0003] In the existing hydrogen energy valve design, although some anti-leakage measures have been taken, such as adding sealing gaskets and optimizing sealing structures, there are still some limitations in practical applications. For example, sealing gaskets are prone to aging and wear, resulting in reduced sealing performance; and the complexity of the sealing structure also increases the difficulty of manufacturing and maintenance. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of the utility model is to provide a hydrogen energy valve that prevents hydrogen leakage and solves the problems raised in the above background.

[0006] (II) Technical solution

[0007] A hydrogen energy valve for preventing hydrogen leakage comprises a hydrogen energy valve body, one side of the hydrogen energy valve body is connected to a connecting pipe, and one side of the connecting pipe is connected to a flange, an operating ring is movably installed on the outer surface of the connecting pipe, and one side of the operating ring is connected to a sealing pipe, a rubber airbag is installed on the inner wall of the sealing pipe, an air pump is fixedly installed on the outer surface of the hydrogen energy valve body, and one side of the air pump is connected to a rubber air pipe, and one end of the rubber air pipe is connected to the air pump.

[0008] Preferably, fixing plates are fixedly installed on both sides of the air pump, and the fixing plates are fixedly connected to the hydrogen energy valve body through multiple sets of screws. Through the fixed connection between the fixing plates and the screws, the connection between the air pump and the hydrogen energy valve body is more stable, which effectively prevents the air pump from shaking or shifting during operation, thereby improving the stability of the entire system.

[0009] Preferably, a pressure sensor is provided on one side of the outer surface of the hydrogen energy valve body, and a display screen is provided on one side of the outer surface of the pressure sensor. The pressure sensor can monitor the pressure changes inside the valve or in the connecting pipe in real time, and the display screen connected to the pressure sensor can intuitively display the current pressure value. This enables operators to quickly understand the pressure status of the system without the need for additional tools or equipment.

[0010] Preferably, a buzzer sensor is provided on the outer surface of the top of the air pressure sensor, and an alarm light is installed at one end of the air pressure sensor. When the air pressure sensor detects that the air pressure exceeds the preset safety range, the buzzer sensor will emit a buzzer sound and the alarm light will light up. This multiple warning mechanism can ensure that attention can be drawn in time even in a noisy environment or when the operator's attention is distracted, avoiding missing important warning information.

[0011] Preferably, a limiting ring is fixedly installed on one side of the connecting pipe, and the limiting ring prevents the operating ring from detaching.

[0012] Preferably, the outer surface of the operating ring is serrated and wrapped with rubber. The serrated design can increase friction, making it easier for the operator to grasp and rotate the operating ring. The rubber wrapping can provide better anti-slip properties and feel, making the operation more comfortable and stable.

[0013] Preferably, an air valve is provided at one end of the rubber air tube, and the air valve can control the on-off of the airflow in the rubber air tube, so as to close the airflow when inflation is not needed, thereby saving energy.

[0014] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0015] 1. The utility model makes the sealing tube cover the flange through the sliding operating ring, which enhances the sealing performance when the valve is closed and effectively prevents the leakage of hydrogen at the connection. The introduction of the rubber airbag forms a tight sealing barrier between the flange and the sealing tube, which significantly improves the sealing effect.

[0016] 2. The utility model can monitor the air pressure changes inside the valve or in the connecting pipe in real time through the air pressure sensor, and the display screen connected to the air pressure sensor can intuitively display the current air pressure value. This enables the operator to quickly understand the air pressure status of the system without the need for additional tools or equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 1-5 , an embodiment provided by the utility model:

[0025] A hydrogen energy valve for preventing hydrogen leakage comprises a hydrogen energy valve body 1, a connecting pipe 111 is connected to one side of the hydrogen energy valve body 1, a flange 512 is connected to one side of the connecting pipe 111, an operating ring 2 is movably mounted on the outer surface of the connecting pipe 111, a sealing pipe 3 is connected to one side of the operating ring 2, a rubber airbag 112 is mounted on the inner wall of the sealing pipe 3, an air pump 6 is fixedly mounted on the outer surface of the hydrogen energy valve body 1, a rubber air pipe 5 is connected to one side of the air pump 6, and one end of the rubber air pipe 5 is connected to the air pump 6.

[0026] Furthermore, fixing plates 7 are fixedly installed on both sides of the air pump 6, and the fixing plates 7 are fixedly connected to the hydrogen energy valve body 1 through multiple sets of screws 8. Through the fixed connection between the fixing plates 7 and the screws 8, the connection between the air pump 6 and the hydrogen energy valve body 1 is more stable, which effectively prevents the air pump from shaking or shifting during operation, thereby improving the stability of the entire system.

[0027] Furthermore, a pressure sensor 9 is provided on one side of the outer surface of the hydrogen energy valve body 1, and a display screen is provided on one side of the outer surface of the pressure sensor 9. The pressure sensor 9 can monitor the pressure changes inside the valve or in the connecting pipe in real time, and the display screen connected to the pressure sensor 9 can intuitively display the current pressure value. This enables the operator to quickly understand the pressure status of the system without the need for additional tools or equipment.

[0028] Furthermore, a buzzer sensor 911 is provided on the outer surface of the top of the air pressure sensor 9, and an alarm light 912 is installed at one end of the air pressure sensor 9. When the air pressure sensor 9 detects that the air pressure exceeds the preset safety range, the buzzer sensor 911 will emit a buzzer sound, and the alarm light 912 will light up. This multiple warning mechanism can ensure that attention can be drawn in time even in a noisy environment or when the operator's attention is distracted, so as to avoid missing important warning information.

[0029] Furthermore, a limit ring 4 is fixedly installed on one side of the connecting pipe 111 , and the limit ring 4 prevents the operating ring 2 from being separated.

[0030] Furthermore, the outer surface of the operating ring 2 is serrated, and the outer surface of the operating ring 2 is wrapped with rubber. The serrated design can increase friction, making it easier for the operator to grasp and rotate the operating ring 2. The rubber wrapping can provide better anti-slip properties and feel, making the operation more comfortable and stable.

[0031] Furthermore, an air valve 511 is provided at one end of the rubber air tube 5. The air valve 511 can control the on-off of the airflow in the rubber air tube 5, so as to close the airflow when inflation is not needed, thereby saving energy.

[0032] Working principle: First, the connecting pipe 111 of the hydrogen energy valve body 1 is safely and reliably connected to other pipelines through the flange 512 to ensure the smooth flow of hydrogen and the initial sealing effect. Then, the operator will slide the operating ring 2 on the outer surface of the connecting pipe 111. This operation will cause the sealing pipe 3 to move along the direction of the connecting pipe 111 and finally completely cover the flange 512. Through this step of operation, the valve is further sealed in the closed state, effectively preventing the leakage of hydrogen at the connection. Finally, by driving the air pump 6, the airflow generated by the air pump 6 will be accurately transmitted to the rubber airbag 112 through the rubber air pipe 5. As the airflow is continuously filled, the rubber airbag 112 will gradually expand and fit tightly between the flange 512 and the sealing pipe 3 to form a sealed barrier. This inflatable sealing structure not only provides an additional sealing effect, but also can be adaptively adjusted according to different pressure requirements, ensuring the safety and stability of hydrogen transmission.
