WHAT DOES THERMIONIC VALVE MEAN IN ENGLISH?

thermionic valve

Vacuum tube

In electronics, vacuum tube, electron tube, tube, or valve is a device that controls electric current through a vacuum in a sealed container. Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. This type is called a thermionic tube or thermionic valve. A phototube, however, achieves electron emission through the photoelectric effect. Not all electron tubes contain vacuum: gas-filled tubes are devices that rely on the properties of a discharge through an ionized gas. The simplest vacuum tube, the diode, contains only two elements; current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode, or in conventional current terms, anode to cathode. Tubes with one grid or more grids between cathode and anode, allow the control of the current between the two electrodes. Tubes with grids can be used as electronic amplifiers, rectifiers, electronically controlled switches, oscillators, and for other purposes.

Definition of thermionic valve in the English dictionary

The definition of thermionic valve in the dictionary is an electronic valve in which electrons are emitted from a heated rather than a cold cathode.
