A high-sealing vacuum valve

Abstract

This utility model discloses a high-sealing vacuum valve, relating to the field of vacuum valve technology. It includes a fixed tube with a valve body installed at one end and a driving component at the top. The advantages of this utility model are: the driving component provides power for the movement of a push-pull rod, which in turn drives the connecting disc to rotate. The connecting disc, as a key transmission component, can synchronously drive multiple sets of sealing discs to slide within the grooves of the valve body. The valve body provides fixed support for the connecting frame, ensuring overall structural stability. The connecting frame provides a sliding track for the slide rod, which precisely limits the movement of the sealing discs, preventing them from shifting and ensuring accurate adjustment. Multiple sets of sealing discs cooperate, forming a structure similar to a sealing ring when closed, effectively preventing gas leakage and achieving gas sealing. The coordinated work of all components ensures that the device can stably and reliably complete the gas sealing and adjustment tasks.

Description

Technical Field

[0001] This utility model relates to the field of vacuum valve technology, and in particular to a high-sealing vacuum valve. Background Technology

[0002] Vacuum valves are key components used to control gas flow in vacuum systems, ensuring stable operation of the system in vacuum or low-pressure environments. Their core functions include isolating, regulating, or guiding gas flow while maintaining the system's vacuum seal.

[0003] In modern vacuum systems, vacuum valves are typically sealed internally by tightening screws. However, this design may encounter problems after prolonged use, particularly regarding sealing. Over time, the tightening force of the screws may gradually weaken due to factors such as temperature changes, vibration, and material fatigue, causing the valve seal to become less tight. When the seal is poor, external air may seep in through the valve, leading to leakage. This not only affects the vacuum level of the system but may also cause a decline in equipment performance and even interfere with experimental results. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Example 1:

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a high-sealing vacuum valve, including a fixed tube 1, a valve body 2 installed at one end of the fixed tube 1, a driving component 3 provided at the top of the fixed tube 1, a main body assembly 4 provided at the bottom of the driving component 3, and a connecting tube 5 provided on one side of the main body assembly 4.

[0028] By setting two sets of fixed pipes 1, it is easy to connect with the valve body 2. By setting the driving component 3, it is easy to drive the main body component 4 to move. By setting the main body component 4, it is easy to facilitate gas flow and gas sealing.

[0029] The main component 4 includes a push-pull rod 41 located at the bottom of the drive component 3. One end of the push-pull rod 41 is fixed with a connecting plate 42. The inner wall of the connecting plate 42 is provided with a sliding groove 43, and the sliding groove 43 is designed to be hexagonal. Multiple sets of sealing discs 46 slide on the inner wall of the sliding groove 43. Multiple sliding rods 45 are fixed on one side of each set of sealing discs 46. A connecting frame 44 is fixed on the inner wall of the valve body 2. The inner wall of the connecting frame 44 is slidably connected to the outer side of the sliding rods 45 and slidably connected to the top of the sealing discs 46.

[0030] By setting the push-pull rod 41, the connecting plate 42 can be easily rotated. After the connecting plate 42 is driven, it can drive multiple sets of sealing plates 46 to move within the slide groove 43. By setting multiple sets of sealing plates 46, gas can be easily blocked. By setting the connecting frame 44, multiple sets of sliding rods 45 can be easily slid. By setting the sliding rods 45, the sealing plates 46 can be easily limited to prevent them from moving or deviating. For reference, see the following video link: https: / / v.douyin.com / P6VUKo58vcs / . The main component 4 in this device is modified based on the mechanical schematic diagram provided in the video.

[0031] Example 2:

[0032] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0033] Specifically, the driving component 3 includes a mounting bracket 31 that is fixed to the top of the two sets of fixed tubes 1. An electronic push rod 32 is rotatably mounted on the inner wall of the mounting bracket 31, and the piston rod of the electronic push rod 32 is rotatably connected to the inner wall of the push-pull rod 41.

[0034] By setting the mounting bracket 31, the electronic push rod 32 can be rotated easily, and the push rod 41 can be moved easily by pushing or pulling it.

[0035] Specifically, the inner wall of the fixed tube 1 is provided with a first groove 6, and the inner wall of the valve body 2 is provided with a second groove 7, and the positions of the first groove 6 and the second groove 7 correspond one-to-one.

[0036] Once the positions of the first groove 6 and the second groove 7 are aligned, the installation block 8 can be easily inserted into the first groove 6 and the second groove 7.

[0037] Specifically, mounting blocks 8 are installed on the inner walls of the first groove 6 and the second groove 7. Multiple sets of mounting bolts 9 are threadedly connected to the inner walls of the mounting blocks 8, and the outer sides of the multiple sets of mounting bolts 9 are threadedly connected to the inner walls of the fixing pipe 1 and the valve body 2, respectively.

[0038] By using the mounting block 8 and mounting bolt 9 together, it is easy to connect the two sets of fixing pipes 1 to the valve body 2, and it is also easy to disassemble them later.

[0039] Specifically, the inner wall of the connecting plate 42 is provided with through holes 14 to facilitate gas flow.

[0040] By providing through hole 14, gas can flow conveniently within fixed pipe 1 and valve body 2.

[0041] Example 3:

[0042] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0043] Specifically, one end of the fixed pipe 1 is fixed with the mounting pipe 10, and the other end of the mounting pipe 10 is fixed with the flange 11.

[0044] The installation pipe 10 facilitates connection with the flange 11.

[0045] Specifically, the inner wall of the flange 11 is threaded with multiple sets of fixing bolts 12, and the outer sides of the multiple sets of fixing bolts 12 are threaded with multiple sets of nuts 13.

[0046] By using flange 11 and multiple sets of fixing bolts 12 together, the connection between fixing pipe 1 and external pipe can be easily made, facilitating the introduction of gas.

[0047] When gas needs to flow, the electronic actuator 32 is activated first. After activation, the actuator 32 pulls the push-pull rod 41 upwards. The upward movement of the push-pull rod 41 causes the connecting plate 42 to rotate within the valve body 2. The rotation of the connecting plate 42 causes multiple sets of sealing discs 46 within the slide groove 43 to move. After the sealing discs 46 move, they cause multiple sets of slide rods 45 to expand outwards within the connecting frame 44. The multiple sets of sealing discs 46 move to the appropriate positions, such as... Figure 4 As shown, the gas can flow smoothly. When sealing the gas is required, first activate the electronic actuator 32. The activation of the electronic actuator 32 drives the push-pull rod 41 to move downward. The downward movement of the push-pull rod 41 causes the connecting plate 42 to rotate within the valve body 2. The rotation of the connecting plate 42 causes multiple sets of sealing discs 46 within the slide groove 43 to move. After the sealing discs 46 move, they cause multiple sets of slide rods 45 to retract inward within the connecting frame 44. The multiple sets of sealing discs 46 move to the appropriate position, such as... Figure 3 As shown, the gas can be sealed.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
