Abstract

The invention discloses a gas sampling device which comprises a gas inlet and an electromagnetic valve, wherein the gas inlet is connected with a gas inlet stop valve, the gas outlet end of the gas inlet stop valve is connected with a pressure reducing valve, the gas outlet end of the pressure reducing valve is connected with an electromagnetic valve filter, and the gas outlet end of the electromagnetic valve filter is connected to the gas inlet end of the electromagnetic valve; the air outlet end of the electromagnetic valve is connected with a metering pump through a metering pump air inletpipe, and an outlet of the metering pump is connected with a one-way valve and a collector stop valve through a metering pump air outlet pipe; and the air outlet end of the one-way valve is connectedwith a quick dismounting and replacing block, a collector front-end stop valve, a collector and a collector rear-end stop valve. Gas sampling can be circularly carried out at set time intervals, the collected gas is collected into the collector through the metering pump, the averaging performance is good, the device is simple and practical, sampling can be finished only through the quick dismounting and replacing block, and the device is suitable for the field and can automatically collect the gas.

Description

technical field [0001] The invention relates to gas sampling, in particular to a gas sampling device. Background technique [0002] In the field of gas sampling, it is often necessary to collect the sampled gas into a specific container, and then perform component analysis. The current common method is to use a gas collection pump to forcibly collect the sampled gas into a specific container. This method has the following disadvantages. Disadvantage 1, only instantaneous gas can be collected, which does not represent the average characteristics. Disadvantage 2, the acquisition device is complicated, and each acquisition needs to be disassembled once. Disadvantage 3, the power supply mode is powered by a power supply, which is not suitable for outdoor environments. Disadvantage 4, the collection mode is manual and does not have the function of automatic collection. Disadvantage 5, not suitable for high pressure (10MPa) gas collection. Contents of the invention [0003...
