Detailed description of the invention
Below in conjunction with drawings and Examples, the embodiment of the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the embodiment of the present invention, but not the restriction to the embodiment of the present invention.It also should be noted that, for convenience of description, illustrate only the part relevant to the embodiment of the present invention in accompanying drawing but not entire infrastructure.
Embodiment one
With reference to the structural representation that Fig. 1, Fig. 1 are embodiment of the present invention oxygen concentration calibrating installation.
In a first embodiment, this oxygen concentration calibrating installation comprises:
Oxygen concentration sensor (1), secondary three-way magnetic valve (2), main three-way magnetic valve (3) and Venturi tube structure (4); One end of described Venturi tube structure (4) is connected with one end of described secondary three-way magnetic valve (2), the other end of described secondary three-way magnetic valve (2) and described oxygen concentration sensor (1), the other end of described Venturi tube structure (4) is connected with one end of described main three-way magnetic valve (3), and the other end of described main three-way magnetic valve (3) is connected with described oxygen concentration sensor (1).
Preferably, the first embodiment, the air intake end of described Venturi tube structure (4) is directly accessed air by described secondary three-way magnetic valve (2), and disconnects with described oxygen concentration sensor (1);
The gas that described Venturi tube structure (4) exports is received the gas circuit of described oxygen concentration sensor (1) by described main three-way magnetic valve (3), and outputs to respirator outlet, and the oxygen concentration that described respirator exports is 100%.
Preferably, the second embodiment, the air intake end of described Venturi tube structure (4) is directly accessed described oxygen concentration sensor (1) and is connected to atmospheric environment by respirator outlet by described secondary three-way magnetic valve (2);
The gas that described Venturi tube structure (4) exports directly is received atmospheric environment by described main three-way magnetic valve (3), disconnects with described oxygen concentration sensor (1).
