Description
Technical field
The utility model relates to a kind of air distributing device, relates in particular to a kind of multi-channel intelligent air distributing device.
Background technique
Its inside of high pressure SF6 switching device is filled with SF6 gas, in switch breaking operation process, under factors such as arcing, corona, sparkover and partial discharge, high temperature; SF6 gas can decompose, and its decomposition can become the corrosivity electrolyte after running into moisture, wherein some high toxicity analyte; Like SF4, S2F2, S2F10, SOF2, HF and SO2, their Diazolidinyl Ureas, mucous membrane are if intake is big; Also can cause dizziness and pulmonary emphysema, even the causing death.To this situation need be under laboratory and various environment integrated analog gas composition, so just need an air distributing device.
Summary of the invention
The technical problem that the utility model will solve is: can decompose to SF6 gas, its decomposition can become the corrosivity electrolyte after running into moisture, wherein some high toxicity analyte; Like SF4, S2F2, S2F10, SOF2, HF and SO2, their Diazolidinyl Ureas, mucous membrane are if intake is big; Also can cause dizziness and pulmonary emphysema; Even the causing death, need be under laboratory and various environment integrated analog gas composition, a kind of multi-channel intelligent air distributing device is provided.
In order to overcome the defective that exists in the background technique; The utility model solves the technological scheme that its technical problem adopted: this multi-channel intelligent air distributing device is made up of three pipelines; Wherein pipeline one is composed in series by suction port and needle type valve, pressure transducer and electron mass flowmeter successively; Pipeline two is composed in series by dilution suction port and needle type valve, pressure transducer and electron mass flowmeter successively, and pipeline three is composed in series with needle type valve, pressure transducer and electron mass flowmeter by the dilution suction port successively, and pipeline one and pipeline two one-level that is connected in parallel is diluted; Secondary dilution that one-level is diluted and pipeline three is connected in parallel, secondary dilution connect kind gas and export.
According to another embodiment of the utility model, comprise that further said pipeline three is composed in series by dilution suction port and needle type valve, pressure transducer and electron mass flowmeter successively, and pipeline three is at least 1.
The beneficial effect of the utility model is: this multi-channel intelligent air distributing device overall structure is simple; Be that a kind of can the setting voluntarily according to ratio mixed the device of exporting; Electron mass flowmeter wherein utilizes the characteristics of its highi degree of accuracy, high accuracy, accurately controls the input quantity of each gas composition composition; This multi-channel intelligent air distributing device is provided with a plurality of pipelines, thereby reaches the purpose of dilution, configuration desired concn appearance gas.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
