The relative prior art of the present invention has outstanding substantive distinguishing features and marked improvement; Specifically, this object gas gauging table is on the basis of existing gas meter, has increased the object gas recognition device; Promptly; The object gas that identifies is flowed to gas meter measures, and non-object gas is directly drained without gas meter, its have design science, simple and practical, the construction cycle is short, R&D costs are low, be easy to transform, advantage that improvement cost is low.
Description of drawings
Fig. 1 is the structural representation of said object gas gauging table.
Embodiment
Through embodiment, technical scheme of the present invention is done further detailed description below.
As shown in Figure 1; A kind of object gas gauging table, it comprises gas meter 7, microcontroller circuit 1, target gas sensing device 2, first controllable electromagnetic valve 5, second controllable electromagnetic valve 6, solenoid valve power supply 8, first three-way connection 3 and second three-way connection 4;
Wherein, Said target gas sensing device 2 is installed in said first three-way connection 3; Said microcontroller circuit 1 connects the content that said target gas sensing device 2 is used to detect object gas, and two solenoid control ends of said microcontroller circuit 1 connect the control end of control end and said second controllable electromagnetic valve 6 of said first controllable electromagnetic valve 5 respectively so that realize the control to first controllable electromagnetic valve and second controllable electromagnetic valve according to the content of object gas; Said solenoid valve power supply 8 is electrically connected said first controllable electromagnetic valve 5 and said second controllable electromagnetic valve 6 respectively so that working power to be provided;
Said first three-way connection 3 includes air intake opening 31, first gas outlet 33 and second gas outlet 32; Said second three-way connection 4 includes gas outlet 41, first air intake opening 43 and second air intake opening 42, and first gas outlet 33 of said first three-way connection 3 connects first air intake opening 43 of said second three-way connection 4; In other embodiments, said first three-way connection and said second three-way connection also can be one, that is, first gas outlet of said first three-way connection is that one is connected with first air intake opening of said second three-way connection.
Install first gas outlet 33 of said first controllable electromagnetic valve, 5 corresponding said first three-way connections 3, so that the conducting of first gas outlet 33 of said first three-way connection 3 of said first controllable electromagnetic valve, 5 controls; Perhaps, first air intake opening 43 of said first controllable electromagnetic valve, 5 corresponding said second three-way connections 4 is installed, so that the conducting of first air intake opening 43 of said second three-way connection 4 of said first controllable electromagnetic valve, 5 controls;
