Abstract

The multi-channel gas distribution and distribution device comprises a gas inlet pipe, a buffer tank and a gas outlet pipe which are sequentially connected, a gas inlet is formed in one end of the gas inlet pipe, a first electromagnetic valve and a first flow controller are arranged on the gas inlet pipe, a blow-down pipe is arranged at one end of the upper portion of the buffer tank, and a second electromagnetic valve and a second flow controller are arranged on the blow-down pipe. The blow-down pipe is connected with a temperature and pressure sensor, the temperature and pressure sensor is connected with a second electromagnetic valve, the second electromagnetic valve is connected with a second flow controller, the other end of the upper portion of the buffer tank is connected with a pressure release valve, and a pressure release opening is formed in the upper end of the pressure release valve; the air outlet pipe is connected with branch air outlet pipes in a branching mode, the branch air outlet pipes are arranged in a consistent mode and connected with branch electromagnetic valves, the other ends of the branch electromagnetic valves are connected with branch flow controllers, and the branch flow controllers are connected with branch air outlets. According to the use method, a plurality of branches are detected respectively. According to the method, the sulfur hexafluoride detection time can be shortened to 1 day, and the detection efficiency is greatly improved.

Description

Technical field [0001] The present invention relates to the field of hexafluoride sulfur detection, and more particularly to a multi-channel gas distribution device for hexafluoride sulfur detection and a method of use thereof. Background technique [0002] At present, hexafluoride is a large number of applications due to excellent insulated arc extinguishing capacity, and the usage is 80% of the total ownership of the world. Due to the specialty in the field of electricity, hexafluoride sulfur is required to start the factory and before use. However, the test of hexafluoride sulfur is required for 10 tests, according to the traditional one-by-item detection method, each bottle needs to consume 3 days to complete In the face of emergency detection tasks, more manure and material investment are often needed, and the test efficiency of hexafluoride has become an urgent problem. [0003] China Patent CN201610336894.0 discloses a rapid recovery gasket of a molten fluoride and a ferro...
