Abstract
The utility model discloses an optic methane detector. The optic methane detector comprises a detector body, wherein an air inlet pipe and an air suction rubber ball are arranged on the detector body. The optic methane detector is characterized in that one end of the air inlet pipe is connected with a moisture adsorption pipe, the other end of the air inlet pipe is provided with a three-way pipe which is connected with one end of a methane gas control valve and one end of a carbon dioxide gas control valve respectively, the other end of the methane gas control valve is connected with a carbon dioxide suction pipe, and the other end of the carbon dioxide gas control valve is connected with outside air. The detector is reasonable in structure, convenient to use and capable of solving the technical problem that the prior art is tedious in measurement, so that measurement results are accurate.
Description
Technical field the utility model belongs to mine gas Gas Thickness Detecting Technology field, relates to a kind of optics methane detector.
Background technology is often used optics methane tester in the mine industry concentration of gases such as the methane in the mine, carbon dioxide is measured.What use in the work at present is AQG-1 optics methane detector mostly; This instrument is easy to carry, simple to operate; But the draft tube of this instrument is connected with carbon dioxide absorption tube through piston; Can directly measure, but when measuring density of carbon dioxide gas, need draft tube extracted from carbon dioxide absorption tube and measure gas concentrations such as methane.The pilot of each test has several to tens, thereby this method of extracting back and forth is not only loaded down with trivial details but also error is increased potential safety hazard is increased.
The purpose of summary of the invention the utility model is to solve prior art to have the technical matters of tube drawing troublesome poeration back and forth; A kind of novel optical methane detector is provided; Make the staff in test during harmful gas concentration, can access easy, accurate, to reduce the unsafe risk of mine operation.
A kind of optics methane detector of the utility model is on the basis of ordinary optical methane detector, to improve to realize that it comprises fuselage, and said fuselage is provided with draft tube and air-breathing rubber ball; Its main points are that an end of draft tube is connected with the moisture content absorption tube; The other end is provided with a three-way pipe and connects methane gas operation valve and carbon dioxide operation valve respectively; The other end of said methane gas operation valve is connected with carbon dioxide absorption tube, and the other end of said carbon dioxide operation valve is connected with external air.
The utility model can be measured gas with various concentration through the open and close of operation valve, and pushing air-breathing rubber ball, that draft tube is carried out is air-breathing.When measuring gas concentration lwevel, making the carbon dioxide operation valve be in opening methane gas operation valve is in closed condition and can measures; When measuring gas concentration and content such as methane, making the carbon dioxide operation valve be in closed condition methane gas operation valve is in opening and can measures.
The utility model is rational in infrastructure easy to use, has solved prior art and has measured loaded down with trivial details technical matters, makes measurement result more accurate.
Appended drawings is the utility model structural representation.
Among the figure 1, air-breathing rubber ball 2, draft tube 3, carbon dioxide operation valve 4, methane gas operation valve 5, moisture content absorption tube 6, fuselage 7, carbon dioxide absorption tube 8, three-way pipe
Embodiment is according to accompanying drawing, and it comprises fuselage 6 the utility model, and said fuselage 6 is provided with draft tube 2 and air-breathing rubber ball 1; One end of draft tube 2 is connected with moisture content absorption tube 5; The other end is provided with a three-way pipe 8 and connects methane gas operation valve 4 and carbon dioxide operation valve 3 respectively; The other end of said methane gas operation valve 4 is connected with carbon dioxide absorption tube 7, and the other end of said carbon dioxide operation valve 3 is connected with external air.
When measuring gas concentration lwevel, open carbon dioxide operation valve 3, close methane gas operation valve 4, push air-breathing rubber ball 1 and make draft tube 2 carry out air-breathing can the measurement; When gas concentrations such as measurement methane, open methane gas operation valve 4, closing carbon dioxide gas control valve 3 pushes air-breathing rubber ball 1 and makes draft tube 2 carry out air-breathing can the measurement.
