Thyratron Inflation System

Abstract

The invention discloses a thyratron gas-filling system. The system comprises a thyratron put in a closed cavity; the thyratron is communicated with a hydrogen gas storage tank through a pipe; a station valve and a hydrogen gas filling micrometering valve are arranged in sequence on the pipe between the thyratron and the hydrogen gas storage tank; the hydrogen gas storage tank is connected to a first metal hydride hydrogen gas storage device through a pipe; a hydrogen gas inlet valve, a first isolation valve and a first hydrogen gas storage valve are arranged in sequence on the pipe between the hydrogen gas storage tank and the first metal hydride hydrogen gas storage device; two pipe branches are arranged in sequence on the pipe between the hydrogen gas inlet valve and the first isolation valve; connection valves and empty valves are arranged on the two pipe branches respectively; a first film vacuum meter is arranged on the hydrogen gas storage tank; a second film vacuum meter is arranged on the pipe between the thyratron and the station valve. Through the adoption of the thyratron gas-filling system, the effect of filling high-purity and pressure-controlled hydrogen gas, deuterium gas and the like into the thyratron can be achieved.

Description

technical field [0001] The invention relates to a thyratron inflation system. Background technique [0002] With the increase of thyratron production and the improvement of thyratron production efficiency, the traditional method of purifying hydrogen by palladium alloy membrane diffusion method has more and more limitations, especially when the process requires a large amount of hydrogen, the current palladium alloy The purification rate of the membrane diffusion method cannot be satisfied. In order to improve the speed and efficiency of purifying hydrogen by the palladium alloy membrane diffusion method, the thickness of the palladium alloy tube can be reduced, the working temperature of the palladium alloy tube can be increased, and the pressure difference at both ends of the palladium alloy tube can be increased, but this will easily cause the palladium alloy tube to leak. Air life is severely shortened. At the same time, palladium is a precious metal, which is expensiv...

In order to improve the speed and efficiency of purifying hydrogen by the palladium alloy membrane diffusion method, the thickness of the palladium alloy tube can be reduced, the working temperature of the palladium alloy tube can be increased, and the pressure difference at both ends of the palladium alloy tube can be increased, but this will easily cause the palladium alloy tube to leak. Air life is severely shortened

At the same time, palladium is a precious metal, which is expensive, resulting in higher costs
