Description
Technical field
The present invention relates to a kind of sensor for detecting liquid chemical leakage, belong to sensor technical field.
Background technology
The leakage accident that chemical liquid easily happens suddenly during storage, packing, use, and hazardous chemical is being let out
Environmental pollution is easily caused after leakage, even more serious even occurs the serious accidents such as fire, blast.Therefore, if worked as
It during hazardous chemical liquid leakage, can timely be perceived, can timely be handled, avoid the generation of major accident.At present
Monitoring for dangerous liquid chemicals is typically monitored using Video Remote or the method for manual inspection.Video monitor, which exists, to be regarded
Feel blind area and judge that leakage is more difficult, manual inspection equally can not timely and effectively find chemical leakage, and work
Intensity is big.So for the demand of this kind of dangerous liquid leak detection, at present both at home and abroad also without highly developed product or
Effective solution.
The content of the invention
A kind of the present invention is intended to provide sensor for detecting liquid chemical leakage.
In order to achieve the above object, the present invention is made up of matrix, film body, sensing element, and described matrix is a cavity knot
Structure, hole is provided with the side of matrix, film body is placed in inside cavity, and the hole on matrix is covered into sealing；Sensing element is placed in this
Inside seal cavity, there is cable on sensing element, cable is drawn through matrix to outside.
As the oil, gasoline, diesel oil, benzene,toluene,xylene, ortho-xylene, paraxylene, styrene, the Na Fu that have leakage
Tower (industrial naptha), octyl acetate, methyl methacrylate, acetone, hexanol, nonyl alcohol -5 (ethanol is on C9), dioctyl -, B-
Picoline, dimethyl acetamide, dichloro propylene, dichloroethylene, trichloro ethylene, dichloromethane, trichloroethanes, MEK, first
When the chemical liquids such as base pyrrolidones, isopropanol contact through the hole on matrix with film body, film body reacts with chemical liquid,
Rupture, chemical liquid will enter cavity from the hole of matrix, and chemical liquid will contact induction element, sensing element and change
Liquid, which reacts, produces electric signal, and electric signal is spread out of by cable.
The sensing element can be that sensing element, the film bodies such as liquid or light react with chemical liquid, rupture
Afterwards, liquid or light can enter inside cavity, and liquid or the reaction of the sensing element such as light and liquid or light produce electric signal, electricity
Signal is spread out of by cable.
Small volume of the present invention, is easily installed arrangement, and energy agility detects leakage liquid, while its closed cavity knot
Structure, there is good environmental suitability, be not likely to produce wrong report.

Embodiment
Technical solution of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, for it is a kind of detect liquid leakage sensor embodiment 1, by matrix 1, upper lid 2, lower cover 3,
Film body 4, sensing element 5, cable 6 form.Matrix 1 is a cylindrical structure, is metal or plastic material, is distributed with very on cylinder
It is porous；The gluing inwall in matrix 1 of film body 4, and the aperture on matrix 1 is blocked into sealing；Upper lid 2, lower cover 3 are respectively arranged in base
The both ends of body 1；Matrix 1, upper lid 2, lower cover 3, film body 4 just constitute a closed cavity, and it is closed that sensing element 5 is placed in this
In cavity, there is cable 6 on sensing element 5, cable 6 is drawn through upper lid 2.
As the oil, gasoline, diesel oil, stupid, toluene, dimethylbenzene, ortho-xylene, paraxylene, styrene, the Na Fu that have leakage
Tower (industrial naptha), octyl acetate, methyl methacrylate, acetone, hexanol, nonyl alcohol -5 (ethanol is on C9), dioctyl -, B-
Picoline, dimethyl acetamide, dichloro propylene, dichloroethylene, trichloro ethylene, dichloromethane, trichloroethanes, MEK, first
When the chemical liquids such as base pyrrolidones, isopropanol contact film body 4, film body 4 reacts with chemical liquid, ruptures, chemistry
Liquid will enter cavity from the aperture of matrix 1, and chemical liquid will contact induction element 5, sensing element 5 and chemical liquid hair
Raw reaction produces electric signal, and electric signal is spread out of by cable 6.
As shown in figure 3, for a kind of embodiment 2 for the sensor for detecting liquid leakage, its general principle and the phase of embodiment 1
Together, except that the side of matrix is several elongated holes.
