Description

Technical Field

[0001] The utility model relates to the technical field of vacuum tubes, and particularly to an explosion-proof vacuum tube. Background Art

[0002] A vacuum tube is a key electronic component that utilizes the movement of electrons in a vacuum environment to achieve functions such as signal amplification, rectification, and oscillation. It once occupied an important position in radio, audio amplification, and early computer systems. Although its applications have decreased with the development of semiconductor devices, it still has irreplaceable advantages in high-frequency and high-power applications.

[0003] Traditional vacuum tubes are usually encapsulated by a glass cover, and the inside of the tube maintains a vacuum state so that electrons can move quickly and efficiently. However, when this glass cover is subjected to external impact or extreme environmental influences, it may crack. Since the inside is in a vacuum state, if the glass cover cracks, external air will quickly rush in, causing a sudden change in internal pressure. This pressure change may trigger an explosion, resulting in equipment damage and posing a threat to the surrounding environment and personal safety. In view of this, we propose an explosion-proof vacuum tube. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an explosion-proof vacuum tube to solve the problems raised in the above background art.

[0015] 1. For this explosion-proof vacuum electron tube, by arranging an explosion-proof film between the inner tube and the outer tube, it can effectively absorb impacts, prevent the tube body from bursting, and avoid splashing of fragments, thereby providing additional safety protection for personnel and equipment.

Two anode plates 6 arranged symmetrically left and right are provided between the first mica sheet 5 and the second mica sheet 10 to collect electrons for signal amplification and processing. A cathode sheet 7 is provided between the two anode plates 6 to release electrons to form electron flow. A grid 8 is provided outside the cathode sheet 7 to control the direction of electron flow. An getter disk 11 is provided at the top of the second mica sheet 10 to maintain the internal vacuum state of the vacuum tube 3 and extend the tube life;

[0030] The vacuum tube 3 includes an inner tube 30 and an outer tube 31 to form a double-layer structure to provide additional physical strength and protection. An explosion-proof film 32 is provided between the inner tube 30 and the outer tube 31 to absorb impacts, prevent the inner tube 30 and the outer tube 31 from directly bursting, effectively avoid the sputtering of fragments of the inner tube 30 and the outer tube 31, and prevent harm to the staff;

[0031] A metal protection part 4 is provided outside the base 1. The metal protection part 4 includes an annular fixed seat 40 fixedly connected to the outside of the base 1 to provide a stable support for the metal cover 41. A detachable metal cover 41 is threadedly connected to the outside of the annular fixed seat 40 to cover the vacuum tube 3 to provide external protection and allow air flow for heat dissipation. The vacuum tube 3 is located inside the metal cover 41 to protect the outside of the vacuum tube 3 and enhance the overall damage resistance.

[0032] In this embodiment, the first mica sheet 5 is located directly below the second mica sheet 10. Multiple fixing columns 50 are provided at the bottom of the first mica sheet 5. The bottom ends of the fixing columns 50 are fixedly connected to the inside of the base 1 to connect and support the first mica sheet 5 and the base 1.

[0033] Specifically, two beam-forming screens 9 arranged symmetrically left and right are provided between the two anode plates 6. The grid 8 is located between the two beam-forming screens 9 to concentrate the electron flow and improve the efficiency of the electron tube.

[0034] Furthermore, multiple anti-slip bumps 400 arranged in an annular array are provided at the bottom of the outer wall of the annular fixed seat 40. The anti-slip bumps 400 and the annular fixed seat 40 are of an integrally formed structure, which is beneficial for the staff to firmly press the annular fixed seat 40 with their hands, so that the staff can twist the metal cover 41 with their other hand.

[0035] Furthermore, multiple heat dissipation holes 410 for air flow to pass through are opened on the outer wall of the metal cover 41 for air flow to pass through for heat dissipation.

[0037] When the explosion-proof vacuum electron tube of this embodiment is in use, the base 1 of the electron tube is connected to an external circuit through the pins 2 to ensure that electronic signals can be smoothly input and output. The explosion-proof film 32 between the inner tube 30 and the outer tube 31 is used to absorb internal and external impacts, preventing the tube body from directly bursting and ensuring safety. Ensure that the metal protection part 4 and the metal cover 41 are correctly installed, provide stable support through the annular fixing seat 40, and enhance the anti-damage ability. The heat dissipation holes 410 on the metal cover 41 allow air circulation to ensure that heat can dissipate when the electron tube is operating at high power. When an external object collides with the vacuum electron tube, the metal cover 41 can effectively protect the vacuum tube 3 and prevent the vacuum tube 3 from being collided and burst. If the metal cover 41 is damaged, it can be easily disassembled and replaced to ensure convenient maintenance and continuous use. Through these steps, the advantages of the explosion-proof vacuum electron tube can be effectively utilized to ensure its safe and efficient operation in various environments.
