Abstract
Description
Technical Field
[0001] This utility model relates to a ball valve for a hydrogen compressor, belonging to the technical field of ball valves for hydrogen compressors. Background Technology
[0002] In the field of hydrogen compressor ball valve technology, traditional hydrogen compressor ball valves typically employ a fixed-angle opening and closing design. The valve core can only achieve a fully open or fully closed state, making it impossible to precisely adjust the valve core angle according to actual operating conditions. This results in difficulty achieving accurate control under different flow and pressure conditions, often leading to problems such as large flow fluctuations and inaccurate pressure regulation. Utility Model Content
[0003] The technical problem this invention aims to solve is to provide a ball valve for a hydrogen compressor, which addresses the limitations of existing technologies that cannot precisely adjust the valve core angle according to actual operating conditions. This leads to difficulties in achieving accurate control under varying flow and pressure conditions, often resulting in large flow fluctuations and inaccurate pressure regulation.
[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: a ball valve for a hydrogen compressor, including a valve body, the valve body being a hollow structure, a rotating shaft being rotatably mounted on the valve body, one end of the rotating shaft extending into the interior of the hollow structure and a valve core being fixedly mounted thereon, the other end of the rotating shaft extending into the outside of the valve body and a handle being fixedly mounted thereon, a sliding rod being fixedly mounted on the handle facing the side of the valve body, a sliding groove being provided on the valve body, the sliding rod being slidably mounted inside the sliding groove, and a limiting structure for limiting the sliding rod being provided on the valve body.
[0005] By adopting the above technical solution, rotating the handle drives the rotating shaft to rotate, which in turn drives the valve core to rotate, thus achieving connection of the hollow structure. During the movement of the handle, the sliding rod slides inside the sliding groove. When the valve core is opened to a suitable angle, the sliding rod can be limited by the limiting structure, thereby limiting the handle, rotating shaft and valve core. The valve core can be precisely adjusted to any required angle to meet the precise control requirements of different flow and pressure conditions.
[0006] The present invention is further configured such that: the limiting structure includes a guide groove, a guide block, a movable plate, a slot and a limiting part, the guide groove is opened on the valve body, the guide block is slidably disposed inside the guide groove, one end of the guide block extends to the outside of the guide groove and is fixedly connected to the movable plate, one side of the movable plate extends to the top of the sliding groove, the slot is opened on the movable plate, the sliding rod can abut against the slot, and the limiting part is disposed on the movable plate, the limiting part is used to limit the sliding rod.
[0007] The present invention is further configured such that: the limiting part includes a connecting groove, a limiting block, a limiting groove, a lever plate and a spring; the connecting groove is opened on the moving plate; the limiting block is slidably disposed inside the connecting groove; the limiting groove is opened on the sliding rod; one end of the limiting block can extend into the slot and be inserted into the limiting groove; one end of the limiting block extends to the outside of the moving plate and is fixedly connected to the lever plate; and the spring is fixedly disposed between the limiting block and the connecting groove.
[0008] By adopting the above technical solution, the moving plate is pushed to drive the guide block to slide in the guide groove. After the moving plate drives the slot to the appropriate position, the lever is pulled to drive the limiting block to slide in the connecting groove. The limiting block is retracted into the interior of the connecting groove. During the movement, the limiting block compresses the spring. Then, the handle can be turned to drive the sliding rod to move in the sliding groove toward the moving plate. The sliding rod moves and abuts against the inner wall of the slot. At this time, the sliding rod also drives the limiting groove and the limiting block to align. The spring resets and pushes the limiting block to move toward the limiting groove, so that the limiting block is inserted into the interior of the limiting groove, thus completing the limiting of the sliding rod.
[0009] The present invention is further configured such that: a limit bolt is threaded at one end of the movable plate, and one end of the limit bolt can abut against the valve body.
[0010] By adopting the above technical solution, after the moving plate is moved to the appropriate position, the position of the moving plate can be easily fixed by rotating the limit bolt to abut against the valve body.
[0011] The present invention is further configured such that: a pointer is fixedly installed at one end of the moving plate away from the limiting bolt, and a scale is provided on the valve body, and the pointer can be aligned with the scale.
[0012] By adopting the above technical solution, the moving plate moves synchronously with the pointer when it moves, and the pointer can be directed to the corresponding scale position by observing the scale, which makes it convenient for staff to move and adjust the moving plate.
[0013] The present invention is further characterized by having a friction layer on the handle.
[0014] The beneficial effects of this utility model are: rotating the handle drives the rotating shaft to rotate, which in turn drives the valve core to rotate, thus achieving connection of the hollow structure. During the movement of the handle, the sliding rod slides inside the sliding groove. When the valve core is opened to a suitable angle, the sliding rod can be limited by the limiting structure, thereby limiting the handle, rotating shaft and valve core. The valve core can be precisely adjusted to any required angle to meet the precise control requirements of different flow and pressure conditions. Attached Figure Description

Detailed Implementation
[0019] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0020] like Figure 1 and Figure 2 As shown, a hydrogen compressor ball valve includes a valve body 1, which is a hollow structure 2. An inlet and an outlet connected to the hollow structure 2 are fixedly mounted on the valve body 1. A rotating shaft 3 is rotatably mounted on the valve body 1. One end of the rotating shaft 3 extends into the hollow structure 2 and is fixedly mounted with a valve core 4. A sealing layer is provided at the connection between the rotating shaft 3 and the hollow structure 2 to prevent leakage during use. The other end of the rotating shaft 3 extends to the outside of the valve body 1 and is fixedly mounted with a handle 5. A sliding rod 6 is fixedly mounted on the handle 5 facing the valve body 1. A sliding groove 7 is provided on the valve body 1. The sliding groove 7 is horizontally circular. The sliding rod 6 is slidably mounted inside the sliding groove 7. A limiting structure is provided on the valve body 1 to limit the movement of the sliding rod 6.
[0021] like Figure 2 and Figure 3As shown, the limiting structure includes a guide groove 1011, a guide block 1012, a moving plate 1013, a slot 1014, and a limiting part. The guide groove 1011 is formed on the valve body 1, and the opening direction of the guide groove 1011 is the same as that of the sliding groove 7. The guide block 1012 is slidably disposed inside the guide groove 1011 and slides along the opening direction of the guide groove 1011. One end of the guide block 1012 extends to the outside of the guide groove 1011 and is fixedly connected to the moving plate 1013. One side of the moving plate 1013 extends above the sliding groove 7. The slot 1014 is horizontally formed on the moving plate 1013, and the sliding rod 6 can abut against the slot 1014. The limiting part is disposed on the moving plate 1013. The limiting part includes a connecting groove 1021, a limiting block 1022, a limiting groove 1023, a lever 1024, and a spring 1025. The connecting groove 1021 is horizontally opened on the moving plate 1013. The limiting block 1022 is slidably disposed inside the connecting groove 1021. The limiting groove 1023 is horizontally opened on the sliding rod 6. When the sliding rod 6 abuts against the slot 1014, the limiting groove 1023 and the limiting block 1022 are aligned. One end of the limiting block 1022 can extend into the slot 1014 and be inserted into the limiting groove 1023. One end of the limiting block 1022 extends to the outside of the moving plate 1013 and is fixedly connected to the lever 1024. The spring 1025 is fixedly disposed between the limiting block 1022 and the connecting groove 1021. The spring 1025 is in a tensioned state when it is not under force.
[0022] like Figure 2 As shown, a limit bolt 1031 is threaded on one end of the movable plate 1013. One end of the limit bolt 1031 can abut against the valve body 1. When the limit bolt 1031 abuts against the valve body 1, the movable plate 1013 is in a limited state. When the limit bolt 1031 is separated from the valve body 1, the movable plate 1013 can move.
[0023] like Figure 2 As shown, a pointer 1041 is fixedly installed on one end of the movable plate 1013 away from the limit bolt 1031, and a scale 1042 is provided on the valve body 1. The pointer 1041 can be aligned with the scale 1042. A friction layer is provided on the handle 5.
[0024] Rotating handle 5 drives shaft 3 to rotate, which in turn drives valve core 4 to rotate, thus connecting the hollow structure 2. During the movement of handle 5, sliding rod 6 slides inside sliding groove 7. When valve core 4 is opened to a suitable angle, sliding rod 6 can be limited by limiting structure, thereby limiting handle 5, shaft 3 and valve core 4. Valve core 4 can be precisely adjusted to any required angle to meet the precise control requirements of different flow and pressure conditions.
[0025] Pushing the movable plate 1013 causes the guide block 1012 to slide within the guide groove 1011, so that the movable plate 1013 moves the slot 1014 to the appropriate position. Then, pulling the lever 1024 causes the limiting block 1022 to slide within the connecting groove 1021, so that the limiting block 1022 retracts into the interior of the connecting groove 1021. During the movement, the limiting block 1022 compresses the spring 1025. Then, the handle 5 can be rotated to move the sliding rod 6 within the sliding groove 7 towards the movable plate 1013, so that the sliding rod 6 moves and abuts against the inner wall of the slot 1014. At this time, the sliding rod 6 also causes the limiting groove 1023 to align with the limiting block 1022. The spring 1025 resets and pushes the limiting block 1022 towards the limiting groove 1023, so that the limiting block 1022 is inserted into the interior of the limiting groove 1023, thus completing the limiting of the sliding rod 6.
[0026] After the movable plate 1013 is moved to the appropriate position, the limit bolt 1031 is rotated to abut against the valve body 1, so as to fix the position of the movable plate 1013.
[0027] When the movable plate 1013 moves, it drives the pointer 1041 to move synchronously. By observing the scale 1042, the pointer 1041 can be directed to the corresponding scale 1042 position, which makes it convenient for staff to move and adjust the movable plate 1013.
[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
