Description

Technical Field

[0001] The utility model belongs to the technical field of ball valves, and specifically relates to a hydrogen ball valve. Background Technique

[0002] A hydrogen ball valve is a valve used to control and regulate the flow of hydrogen. It is widely used in fields such as hydrogen energy systems, petrochemical industries, and fuel cell vehicles. It mainly consists of parts such as a sphere, a valve stem, a valve seat, a seal, and a driving device, and has functions such as good sealing performance and flexible regulation.

[0003] The hydrogen ball valve opens or closes the valve by rotating the sphere, thereby controlling the flow of hydrogen. When the hole on the sphere aligns with the channel on the valve seat, hydrogen can pass through; when the sphere rotates until the hole is misaligned with the channel, the flow of hydrogen is cut off.

[0004] When the existing hydrogen ball valve is in use, it is installed on the hydrogen transmission pipeline. During use, due to being exposed to the air for a long time, problems such as oxidation and deformation of the valve body occur, and further problems such as poor sealing and hydrogen leakage occur.

At this time, the protective cover 14 can completely cover the valve body main body 1. At the same time, the combination of the two arc-shaped guard plates 15 can limit and protect the pipeline connected to the pipe joint 13. At this time, the first elastic cloth 16 can be tightened around the middle of the pipeline connected to the pipe joint 13 to achieve the sealing of the middle of the pipeline; by providing a protective cover 14 that can be combined on the surface of the valve body main body 1 to protect the valve body main body 1, it can reduce the direct contact between moisture and oxygen in the external air and the valve body main body 1, reduce the problem of oxidation and deformation of the valve body main body 1 during long-term use, and reduce the problem of hydrogen leakage from the valve body main body 1, improving the sealing performance of the valve body main body 1.

[0025] As Figure 4 shown, a plurality of through holes 2 are provided in the middle of the arc-shaped guard plate 15; a top rod 21 is slidably connected in the middle of the through hole 2; a spring 22 is sleeved in the middle of the top rod 21; one end of the spring 22 is fixedly connected to the arc-shaped guard plate 15, and the other end is fixedly connected to the end of the top rod 21; the end of the top rod 21 contacts the first elastic cloth 16; by providing a top rod 21 at the end of the arc-shaped guard plate 15, when the arc-shaped guard plate 15 covers the pipeline connected to the pipe joint 13, the end of the top rod 21 can abut against the first elastic cloth 16. Since the first elastic cloth 16 contacts the pipeline, the top rod 21 can deform under the support of the spring 22 to achieve full contact between the first elastic cloth 16 and the pipeline. At the same time, due to the arrangement of a plurality of top rods 21, when the pipe joint 13 is connected to different pipelines, the arc-shaped guard plate 15 and the first elastic cloth 16 can effectively seal the pipeline; by providing a top rod 21 on the side wall of the first elastic cloth 16, the first elastic cloth 16 can fully seal the valve body main body 1 and the pipeline connected to the pipe joint 13, reducing the problem of the valve body main body 1 being oxidized too quickly due to external air flowing into the protective cover 14 from the arc-shaped guard plate 15. At the same time, the top rod 21 improves the sealing effect of the first elastic cloth 16 on the pipeline connected to the pipe joint 13.

[0026] As Figure 4As shown, a slot 3 is provided on the side wall of the arc-shaped guard plate 15; a rubber sheet 31 is fixedly connected to the side wall of the arc-shaped guard plate 15; the slot 3 is arc-shaped; the rubber sheet 31 is in interference fit with the slot 3; by providing the slot 3 on the side wall of the arc-shaped guard plate 15, when the arc-shaped guard plates 15 are combined, the two opposing arc-shaped guard plates 15 can be fully sealed through the mutual cooperation of the slot 3 and the rubber sheet 31. When combined, the slot 3 on one of the arc-shaped guard plates 15 can be inserted into the slot 3 in the middle of the opposing arc-shaped guard plate 15. At the same time, because the slot 3 is arc-shaped, when the rubber sheet 31 extends into the slot 3, it can move along the arc-shaped inner wall of the slot 3. At this time, the rubber sheet 31 will be in a bent state inside the slot 3; by providing the slot 3 and the rubber sheet 31 in the middle of the arc-shaped guard plate 15, the sealing effect at the joint when the two arc-shaped guard plates 15 are combined can be achieved, reducing the problem of air leakage at the joint of the arc-shaped guard plates 15.

[0027] As Figure 5 shown, a first fixing ring 4 is fixedly connected to the middle of the valve handle 12; a second fixing ring 41 is fixedly connected to the middle of the handle seat 11; a second elastic cloth 42 is connected between the first fixing ring 4 and the second fixing ring 41; by providing the first fixing ring 4 and the second fixing ring 41 in the middle of the handle seat 11 and the valve handle 12, when the valve handle 12 rotates, the first fixing ring 4 rotates synchronously with the valve handle 12. At this time, the second elastic cloth 42 will deform to follow the rotation of the first fixing ring 4. Subsequently, when the valve handle 12 rotates and resets, the second elastic cloth 42 can also maintain the seal at the connection between the handle seat 11 and the valve handle 12 through its own deformation, so as to reduce the influence of oxygen in the air on the connection between the handle seat 11 and the valve handle 12, and improve the stability of the connection between the handle seat 11 and the valve handle 12 on the valve body 1 during long-term use.

[0028] As Figure 5 shown, a plurality of elastic rods 5 are fixedly connected to the side wall of the first fixing ring 4; a plurality of elastic rods 5 are also fixedly connected to the side wall of the second fixing ring 41; the elastic rods 5 are located inside the second elastic cloth 42; by providing a plurality of elastic rods 5 on both the first fixing ring 4 and the second fixing ring 41, the support for the second elastic cloth 42 can be realized, reducing the direct contact between the second elastic cloth 42 and the handle seat 11 and the valve handle 12, and thus reducing the problem of damage to the second elastic cloth 42 caused by friction with the handle seat 11 and the valve handle 12.

[0029] As Figure 5As shown, a desiccant box 6 is fixedly connected to the top of the second fixing ring 41; a plurality of desiccant boxes 6 are provided on the second fixing ring 41; by providing a desiccant box 6 on the top of the second fixing ring 41, when the handle seat 11 and the valve handle 12 are used, the humid gas inside the second elastic cloth 42 can be dried, the connection between the handle seat 11 and the valve handle 12 can be kept dry, and thus the corrosion problem caused by the contact of moisture and humidity at the connection between the handle seat 11 and the valve handle 12 can be reduced.

[0030] During operation, first install the valve body main body 1 in the middle of the hydrogen pipeline. Then, two protective covers 14 can be covered on the valve body main body 1. At this time, the protective covers 14 can completely cover the valve body main body 1. Meanwhile, the combination of the two arc-shaped guard plates 15 can limit and protect the pipeline connected to the pipeline joint 13. At this time, the first elastic cloth 16 can be tightened around the middle of the pipeline connected to the pipeline joint 13 to achieve the sealing of the middle of the pipeline. By providing a push rod 21 at the end of the arc-shaped guard plate 15, when the arc-shaped guard plate 15 covers the pipeline connected to the pipeline joint 13, the end of the push rod 21 can abut against the first elastic cloth 16. Since the first elastic cloth 16 is in contact with the pipeline, the push rod 21 can deform under the support of the spring 22 to achieve full contact between the first elastic cloth 16 and the pipeline. Meanwhile, due to the arrangement of multiple push rods 21, when the pipeline joint 13 is connected to different pipelines, the arc-shaped guard plate 15 and the first elastic cloth 16 can effectively seal the pipeline. By providing a slot 3 on the side wall of the arc-shaped guard plate 15, when the arc-shaped guard plates 15 are combined, the two opposing arc-shaped guard plates 15 can be fully sealed through the cooperation of the slot 3 and the rubber sheet 31. When combined, the slot 3 on one of the arc-shaped guard plates 15 can be inserted into the slot 3 in the middle of the opposing arc-shaped guard plate 15. At the same time, because the slot 3 is arc-shaped, when the rubber sheet 31 extends into the slot 3, it can move along the arc-shaped inner wall of the slot 3. At this time, the rubber sheet 31 will be in a bent state inside the slot 3. By providing a first fixing ring 4 and a second fixing ring 41 in the middle of the handle seat 11 and the valve handle 12, when the valve handle 12 rotates, the first fixing ring 4 rotates synchronously with the valve handle 12. At this time, the second elastic cloth 42 will deform to follow the rotation of the first fixing ring 4. Subsequently, when the valve handle 12 rotates and resets, the second elastic cloth 42 can also maintain the sealing of the connection between the handle seat 11 and the valve handle 12 through its own deformation, so as to reduce the influence of oxygen in the air on the connection between the handle seat 11 and the valve handle 12 and improve the stability of the connection between the handle seat 11 and the valve handle 12 on the valve body main body 1 during long-term use. By providing a plurality of elastic rods 5 on both the first fixing ring 4 and the second fixing ring 41, the support of the second elastic cloth 42 can be realized, reducing the direct contact between the second elastic cloth 42 and the handle seat 11 and the valve handle 12, and thus reducing the damage problem of the second elastic cloth 42 caused by friction with the handle seat 11 and the valve handle 12. By providing a desiccant box 6 on the top of the second fixing ring 41, when the handle seat 11 and the valve handle 12 are in use, the humid gas inside the second elastic cloth 42 can be dried to keep the connection between the handle seat 11 and the valve handle 12 dry, and thus reduce the corrosion problem of the connection between the handle seat 11 and the valve handle 12 caused by contact with moisture and humidity.
