Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Refering to fig. 1, the utility model proposes a kind of internal floating roof tank mixed gas on-line samplings to monitor system, described
Storage tank 1 includes the top end socket 11 of tank body 12 and ellipse, and floating in tank body 1 has an inner floating roof 13；The sampling monitoring system
System includes sampling tree pipe group 2, aspiration pump 3 and gas detection analytical equipment 4；
The sampling tree pipe group 2 is arranged in top end socket 11, if the sampling tree pipe group 2 include main pipe 21 with
Heavenly Stems and Earthly Branches pipe 22,21 one end of main pipe are stretched out outside storage tank 1, and the other end vertically extends several groups branch pipe 22, the branch to both sides
Pipe 22 is spaced set；21 lower end of main pipe is equipped with solenoid valve 23, and the both ends of branch pipe 22 are equipped with minitype pneumatic pump 24；
One end that the main pipe 21 stretches out outside storage tank 1 is connected to the air inlet of aspiration pump 3, the gas outlet of aspiration pump 3 and
