Embodiment Construction

[0009] The present invention will be further described below in conjunction with drawings and embodiments.

[0010] figure 1 Among them, a number of air intake passages 2 and air outlet passages 4 are arranged in the metal block 7 . A sensor 6 is arranged under the metal block 7 , and an air chamber 3 is formed between the metal block 7 and the sensor 6 . The gas enters the air chamber 3 through the air inlet passage 2, reaches the sensor sensing surface 5 of the sensor 6, and is discharged from the air outlet passage 4, the sensor 6 is connected with the signal processing device 8, and the air inlet passage 2 is connected with the air inlet device 9, And a valve I is provided at the air inlet, the air outlet channel 4 is connected with the air receiving device 8, and a valve II is arranged at the air outlet.

Abstract

The invention particularly discloses an integrated air passage system which comprises a metal block, wherein the metal block is internally provided with a plurality of air inlet channels and air outlet channels; a sealed air chamber is formed between a sensor and a metal face on which the air outlet channels and the air inlet channels are located together; the sensor is connected with a signal processing device; the air inlet channels are connected with an air inlet device; a valve I is arranged at an air inlet; the air outlet channels are connected with an air collection device; a valve II is arranged at an air outlet; and a sealing ring is arranged between the metal block and the sensor, and is 'O'-shaped. The integrated air passage system has the benefits that firstly, pipeless connection is realized; secondly, the structure is compact and the internal volume is small; thirdly, the air impermeability is good; and fourthly, the collection and display of data can be realized.

Description

technical field [0001] The invention relates to an integrated gas circuit system. Background technique [0002] In the detection of the gas composition of the packaging container, the gas in the sample passes through the gas path structure and reaches the sensor. In traditional equipment, the gas circuit structure is to connect various components through hoses. There are following disadvantages: 1. The gas path structure is relatively complicated. 2. Poor air tightness. 3. Large internal volume. Contents of the invention [0003] The object of the present invention is to overcome the above problems and provide an integrated gas circuit system, which realizes no pipe connection, good air tightness, compact structure and small internal volume. [0004] The object of the present invention is to adopt following technical scheme to realize: [0005] An integrated air circuit system, which includes a metal block, a number of air inlet channels and air outlet channels are ar...
