Description

Technical Field

[0001] The utility model relates to the technical field of high vacuum angle valves, in particular to a pneumatic multi-position high vacuum angle valve. Background Art

[0002] High vacuum angle valve is an important vacuum system control component, which is mainly used to realize the opening, closing and regulating functions of the gas circuit in a vacuum environment;

[0003] During operation, the existing high vacuum angle valve mainly focuses on realizing the opening and closing functions of the valve to meet the basic needs of the vacuum system or high vacuum environment, but cannot accurately control the flow rate inside the high vacuum angle valve according to the needs of the staff. Due to the inability to accurately control the flow rate, not only will the flow rate fluctuate during the production process, resulting in unstable production conditions, which in turn affects the quality and consistency of the product, but also in specific application scenarios that require precise control of the flow rate (such as precision manufacturing, scientific research, etc.), the existing high vacuum angle valve cannot meet the requirements, thereby limiting its scope of application.

[0004] Therefore, we proposed a pneumatic multi-position high vacuum angle valve to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a pneumatic multi-position high vacuum angle valve, which solves the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A pneumatic multi-position high vacuum angle valve comprises an angle valve body, the upper end surface of the angle valve body is symmetrically fixedly connected with a support plate, the support plates are provided with through grooves, a cylinder is fixedly connected between the upper end surfaces of the support plates, a valve stem is slidably connected with the upper end surface of the angle valve body, one end of the valve stem away from the angle valve body is fixedly connected to the cylinder output end, a height display plate is symmetrically fixedly connected to the outer surface of the valve stem, and the height display plate is slidably connected in the through groove.

[0008] As a further solution of the utility model: the support plate is symmetrically and equidistantly fixedly connected with display lights on the side away from the valve stem, the display lights are electrically connected with buttons on the side close to the through-hole, the buttons are fixedly connected to the side wall of the support plate, the height display panel is fixedly connected with a pressing plate on the side close to the button, and the pressing plates are on the same vertical level as the buttons.

[0009] As a further solution of the utility model: a hollow sealing ring is fixedly connected to the center of the upper end surface of the angle valve body, and the valve stem penetrates and is slidably connected to the hollow sealing ring.

[0010] As a further solution of the utility model: a hollow column is fixedly connected to the outer surface of the hollow sealing ring, a piston rod is slidably connected through one side of the hollow column, a connecting block is fixedly connected to the end of the piston rod away from the hollow column, the hollow column, the hollow sealing ring, the piston rod and the inside of the connecting block are communicated with each other, an air outlet is formed on the upper end surface of the connecting block, and a sealing cover is clamped on the air outlet.

[0011] As a further solution of the utility model: an emergency closing switch is fixedly connected to the upper end surface of the angle valve body, the emergency closing switch is electrically connected to the air cylinder, and the emergency closing switch and the connecting block are on the same horizontal line.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. By setting the height display board, when the air cylinder drives the valve stem to rise and open the angle valve body, it can drive the two pressing plates to press the buttons, turn on the display lights. After the staff observes the corresponding display lights lighting up, they can turn off the air cylinder, thereby controlling the rising height of the valve stem and the flow rate inside the angle valve body. This not only reduces the flow rate fluctuation during the production process, makes the production conditions more stable, and then improves the quality and consistency of the products, but also because the flow rate inside the angle valve body can be accurately controlled, the angle valve body can be applied to more occasions that require precise flow rate control, thus broadening its application range. And through the pressing of the buttons by the pressing plates and the lighting of the display lights, the staff can intuitively understand the rising height of the valve stem and the opening and closing of the angle valve body, so as to more accurately control the flow rate. This intuitive operation method reduces the operation difficulty and improves the work efficiency.

[0014] 2. By setting the hollow sealing ring and the hollow column, during the rising process of the valve stem, if gas leakage occurs, the gas can be collected and the piston rod can be pushed out of the hollow column. This can not only clearly indicate the leakage position, facilitate the staff to quickly locate the problem and repair it, reduce the downtime during the production process, improve the utilization rate and production efficiency of the equipment, but also collect the leaked gas, reduce the amount of gas leaked into the external environment, and help maintain the stability of the vacuum system or high-vacuum environment.

[0015] 3. By setting the emergency closing switch electrically connected to the air cylinder, during the process of the gas leakage pushing the piston rod out of the hollow column, it can drive the connecting block to press the emergency closing switch, push the valve stem into the angle valve body, and close the angle valve body. Thus, in the initial stage of gas leakage, it can quickly respond and automatically close the angle valve body, effectively preventing the further diffusion of the leaked gas and the resulting safety accidents.

Specific embodiments

[0022] The following will clearly and completely describe the technical solutions of the present utility model in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0023] Embodiment:

[0024] As Figures 1-4 shown, a pneumatic multi-position high-vacuum angle valve includes an angle valve body 1. Symmetrically fixed to the upper end face of the angle valve body 1 are support plates 2. Through grooves 7 are formed in the support plates 2. Fixedly connected between the upper end faces of the support plates 2 is a cylinder 3. The valve stem 4 penetrates and is slidably connected to the upper end face of the angle valve body 1. One end of the valve stem 4 away from the angle valve body 1 is fixedly connected to the output end of the cylinder 3. Symmetrically fixed to the outer surface of the valve stem 4 are height display boards 5. The height display boards 5 are all slidably connected within the through grooves 7.

[0025] In this embodiment, as Figure 2As shown in the figure, display lights 8 are symmetrically and equidistantly fixedly connected to the side of the support plate 2 away from the valve stem 4. Electrically connected to the side of the display light 8 close to the penetration side are buttons 9, and the buttons 9 are fixedly connected to the side wall of the support plate 2. Pressing plates 6 are fixedly connected to the side of the height display plate 5 close to the buttons 9, and the pressing plates 6 and the buttons 9 are on the same vertical horizontal line. When the height display plate 5 rises synchronously with the valve stem 4, it can drive the pressing plates 6 on both sides to press the buttons 9 synchronously to turn on the display lights 8.

[0026] In this embodiment, as Figure 3 shown, a hollow sealing ring 10 is fixedly connected to the center of the upper end face of the angle valve body 1, and the valve stem 4 is slidably connected through the hollow sealing ring 10. By providing the hollow sealing ring 10, the connection between the valve stem 4 and the angle valve body 1 can be sealed.

[0027] In this embodiment, as Figure 4 shown, a hollow column 11 is fixedly connected to the outer surface of the hollow sealing ring 10. A piston rod 16 is slidably connected through one side of the hollow column 11. One end of the piston rod 16 away from the hollow column 11 is fixedly connected to a connection block 12. The hollow column 11, the hollow sealing ring 10, the piston rod 16 and the connection block 12 are connected and communicated with each other. An air outlet 13 is provided on the upper end face of the connection block 12, and a sealing cover 14 is clamped on the air outlet 13. When leaked gas enters the hollow sealing ring 10, it will push the piston rod 16 out of the hollow column 11, prompting the staff that there is a leak and collecting the gas. The staff can centrally collect and process the leaked gas through the air outlet 13.

[0028] In this embodiment, as Figure 3 shown, an emergency closing switch 15 is fixedly connected to the upper end face of the angle valve body 1. The emergency closing switch 15 is electrically connected to the cylinder 3. The emergency closing switch 15 and the connection block 12 are on the same horizontal line. When the connection block 12 moves horizontally and contacts the emergency closing switch 15, it will press the emergency closing switch 15 to control the cylinder 3 to push the valve stem 4 into the angle valve body 1.

[0029] The effects achieved by this embodiment are as follows: In the prior art, high-vacuum angle valves mainly focus on realizing the opening and closing functions of the valves to meet the basic requirements in vacuum systems or high-vacuum environments. However, they cannot accurately control the flow rate inside the high-vacuum angle valve according to the needs of the staff. Due to the inability to accurately control the flow rate, not only will flow rate fluctuations occur during the production process, resulting in unstable production conditions, which in turn affect the quality and consistency of products, but also in specific application scenarios that require precise flow rate control (such as precision manufacturing, scientific research, etc.), the existing high-vacuum angle valves cannot meet the requirements, thus limiting their application scope. Compared with the prior art, when the cylinder 3 drives the valve stem 4 to rise and open the angle valve body 1, it can drive the two-sided pressing plates 6 to press the button 9, turning on the display lamp 8. After the staff observes the corresponding display lamp 8 lighting up, they can turn off the cylinder 3 to control the rising height of the valve stem 4 and the flow rate inside the angle valve body 1. This not only reduces the flow rate fluctuations during the production process, makes the production conditions more stable, and thereby improves the quality and consistency of products, but also because it can accurately control the flow rate inside the angle valve body 1, the angle valve body 1 can be applied to more occasions that require precise flow rate control, thus broadening its application scope. Moreover, through the pressing of the button 9 by the pressing plate 6 and the lighting of the display lamp 8, the staff can intuitively understand the rising height of the valve stem 4 and the opening and closing of the angle valve body 1, so as to more accurately control the flow rate. This intuitive operation method reduces the operation difficulty and improves the work efficiency.

[0030] The working process and principle involved in the overall content of the above embodiment are as follows:

[0031] When the staff needs to open the angle valve body 1, they first drive the cylinder 3 to drive the valve stem 4 to slide out from inside the angle valve body 1. As the valve stem 4 rises, the valve stem 4 will drive the height display plates 5 connected to both sides to move upward synchronously in the through slots 7 opened on the support plate 2. At this time, the pressing plates 6 connected to both sides of the height display plates 5 will move upward synchronously. As the pressing plates 6 rise, since the pressing plates 6 and the button 9 are on the same vertical level, the pressing plates 6 will come into contact with the button 9 once and press the button 9. When the pressing plate 6 presses the specified button 9 and turns on the corresponding display lamp 8, the staff can turn off the cylinder 3 to control the rising height of the valve stem 4 and the flow rate inside the angle valve body 1. This not only reduces the flow rate fluctuations during the production process, makes the production conditions more stable, and thereby improves the quality and consistency of products, but also because it can accurately control the flow rate inside the angle valve body 1, the angle valve body 1 can be applied to more occasions that require precise flow rate control, thus broadening its application scope. Moreover, through the pressing of the button 9 by the pressing plate 6 and the lighting of the display lamp 8, the staff can intuitively understand the rising height of the valve stem 4 and the opening and closing of the angle valve body 1, so as to more accurately control the flow rate. This intuitive operation method reduces the operation difficulty and improves the work efficiency;

[0032] During the lifting process of the valve stem 4, if there is leakage at the connection between the valve stem 4 and the angle valve body 1, the leaked air will be collected into the hollow sealing ring 10 and enter the hollow column 11, pushing the piston rod 16 in the hollow column 11 to slide out from the inside of the hollow column 11. This can not only clearly indicate the leakage position, facilitate the staff to quickly locate the problem and repair it, reduce the downtime during the production process, improve the utilization rate and production efficiency of the equipment, but also collect the leaked gas, reduce the amount leaked into the external environment, and contribute to maintaining the stability of the vacuum system or high-vacuum environment;

[0033] During the process of the piston rod 16 sliding out from the inside of the hollow column 11, it will drive the connecting block 12 to move synchronously. Since the connecting block 12 and the emergency closing switch 15 are on the same horizontal line, during the movement of the connecting block 12 following the piston rod 16, it will contact the emergency closing switch 15 and press the emergency closing switch 15, controlling the air cylinder 3 to push the valve stem 4 into the angle valve body 1 to close the angle valve body 1. Thus, in the initial stage of gas leakage, it can quickly respond and automatically close the angle valve body 1, effectively preventing the further diffusion of the leaked gas and the resulting safety accidents.

The preferred embodiments do not describe all the details in detail, nor limit the present utility model to the specific embodiments described. Obviously, many modifications and changes can be made according to the content of this specification.
