Abstract

The invention discloses gas production negative-pressure equipment and a gas detection system. The gas production negative-pressure equipment comprises a controller, a solenoid valve array and a vacuum pump, wherein the controller is used for generating a control signal for controlling the solenoid valve array according to a received electric signal; the solenoid valve array is respectively connected with the controller and the vacuum pump and is used for switching on different solenoid valve sets according to the control signal to realize the control on the flow of the vacuum pump. With the adoption of the gas production negative-pressure equipment provided by the embodiment of the invention, the technical problems in the prior art that gas production of a gas detector can not be controlled so that the sampling speed is low can be solved, so that the technical effect of improving the sampling speed is realized.

Description

technical field [0001] The invention relates to the communication field, in particular to a gas collection negative pressure device and a gas detection system. Background technique [0002] Gas detectors (mass spectrometers) are necessary scientific instruments for scientific experiments. They are widely used in mines and laboratories, and are mainly used for sampling and testing various gases. At present, there are already many gas detectors (mass spectrometers) on the market. However, these gas detectors mainly collect gas samples by means of natural intake, that is, rely on the natural diffusion capacity of the gas for sampling. Individual gas detectors (mass spectrometers) instrument) is equipped with fans or other auxiliary sampling structures to promote the flow of gas, but the overall principle is still to rely on the natural diffusion of gas for sampling. [0003] However, the equipment that adopts the method of gas natural dispersion for sampling mainly has the fol...
