Abstract
The utility model discloses a multi-channel gas acquisition device which mainly comprises a singlechip, a gas sucking pump and a gas guiding device, wherein a gas inlet of the gas sucking pump is connected with the gas guiding device, a gas outlet of the gas sucking pump is connected with a sample gas detecting and conveying pipe, an emptying pipeline is connected beside the sample gas detecting and conveying pipe, a control valve is arranged on the emptying pipeline, a plurality of paths of sampling pipelines are connected to the gas guiding device, electromagnetic valves are arranged on the sampling pipelines, and the electromagnetic valves and the gas sucking pump are controlled by the singlechip. According to the multi-channel gas acquisition device, a plurality of channels are gathered into the gas sucking pump and a gas detection chamber, the connection or disconnection of each channel is determined by controlling connection or disconnection of the electromagnetic valves by the singlechip, and thus the purpose of circularly detecting a plurality of places is achieved. The cost is greatly reduced, and the plurality of channels only share one gas sucking pump and one detection chamber. One detection chamber is capable of detecting gases in a plurality of places, and is convenient to expand.
Description
Technical field
The utility model belongs to field of gas detection, is specifically related to a kind of multi-channel gas harvester.
Background technology
Existing gas collecting device is all generally single channel collection, is the air-breathing technology of single channel gas, and an asepwirator pump can only attract the gas in place, equipment utilization rate variance, and cost is high, and is unfavorable for the gas on-site cycle detection in extensive many places.
Summary of the invention
Based on above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of multi-channel gas harvester.This multi-channel gas harvester adopts multiple passages to be pooled to an asepwirator pump and gas sensing chamber, and the through and off of Single-chip Controlling solenoid valve decide the through and off of each passage, thereby reaches the object of multiple places cycle detection.
The technical solution of the utility model is: a kind of multi-channel gas harvester, it mainly comprises single-chip microcomputer, aspiration pump and gas operated device, the air intake opening of described aspiration pump is connected with gas operated device, on the gas outlet of described aspiration pump, be connected with sample gas and detect gas piping, on described sample gas detection gas piping, also side is connected to emptying pipeline, on described emptying pipeline, is provided with by-pass valve control; On described gas operated device, be connected with multi-channel sampling pipeline, in those sample lines, be provided with solenoid valve; Described solenoid valve and aspiration pump are by Single-chip Controlling.
Further, described single-chip microcomputer is JMDM-COM8MR technical grade No. 8 single-chip microcomputers.
Further, described aspiration pump is electromagnetic pump.
Further, described multi-channel sampling pipeline Wei12 road sample lines.
Further, described multi-channel sampling pipeline Zhong mono-tunnel is calibration sample lines.
Further, described sample gas detects gas piping towards Yang Qi sensing chamber.
Here it should be added that:
(1) single-chip microcomputer: for controlling solenoid valve and aspiration pump work, with other module communications.
(2) solenoid valve: opening/closing by the opening/closing gas circuit that realizes 12 tunnel+1 road zero point corrections of valve.
(3) gas operated device: internal diameter I replaces rapidly gas in device, by 12 sensing point gas collections, is convenient to deliver to sensing chamber and analyzes.
(4) electromagnetic pump: brushless, low noise, for the collection of gas.
The beneficial effects of the utility model are: the one, because multiple passages are only used an asepwirator pump and a sensing chamber, significantly save cost.The 2nd, utilize a sensing chamber just can detect the gas in multiple places, and expansion is convenient.In a word, this multi-channel gas harvester adopts multiple passages to be pooled to an asepwirator pump and gas sensing chamber, and the through and off of Single-chip Controlling solenoid valve decide the through and off of each passage, thereby reach the object of multiple places cycle detection.
