Abstract
The utility model relates to an explosion-proof flashlight whose marking is HBn3e. The whole structure is explosion-proof construction of spark-proof type, and the key position adopts flame-proof type structure. The electric bulb is contained in the explosion-proof chamber. The explosion-proof flashlight which has the advantage of reliable explosion-proof performance can be safely used for various potentially explosive atmospheres except containing hydrogen, acetylene and carbon disulphide.
Description
The utility model relates to a kind of explosion-proof flashlight.
Existing explosion-proof flashlight (West Germany CEAG company product) is made up of transparent panel, reflection shield, cover, interlock, switching device, small electric bulb chamber and the cylindrical shell device of band sealing ring.Housing insulating materials, cylindrical shell device and switching device are the intrinsically safe type blast resistance construction, and whole flashlight is a specific safety type blast resistance construction.Existing explosion-proof flashlight, because small electric bulb cathode contact (producing the key position of spark) communicates with whole cavity, lid and cylindrical shell connecting portion are mainly explosion-proof by flame proof thread, and this connecting portion often is the dismounting position, and therefore the explosion-proof performance of this flashlight is reliable inadequately.
The purpose of this utility model is existing explosion-proof flashlight is improved, and provides a kind of explosion-proof performance reliable, can be applicable to the explosion-proof flashlight of multiple explosive atmosphere.
The measure that the utility model is taked is, torch cover (5) setting-in metal internal layer (18), in lid, metal flame proof seat ring (4) is set, the small electric bulb chamber is designed to the flame-proof type structure, and the metal internal layer of the cover of fixedlying connected with screw thread with metal flame proof seat ring and flame proof small electric bulb chamber and metal flame proof seat ring form flameproof joint (16), (19); The transparent panel of the metal internal layer of cover, metal flame proof seat ring, flame proof small electric bulb chamber and band sealing ring is formed the explosion-proof chamber body.
The lid (5) metal internal layer (18) and the available content of magnesium of metal flame proof seat ring (4) be not more than 0.5%(weight) cast aluminium die casting make.
The available Melamine plastics of chamber body (14) die casting of flame proof small electric bulb chamber is made, and is provided with the not metal connecting piece of saturating screw at the contact site of small electric bulb chamber and anode setting-in.
Through the general structure of above improved explosion-proof flashlight is the intrinsically safe type blast resistance construction, and the cathode contact of the small electric bulb in the flashlight is for producing the key position of spark, and the small electric bulb fragmentation also is easy to generate spark, more than two positions be included in entirely in the flame proof cavity.One end of flame proof cavity is a transparent panel, adopt hermetically-sealed construction, the other end is made up of the metal internal layer of the small electric bulb chamber, metal flame proof seat ring and the cover that adopt explosion separation structure, whole cavity has good explosion insulation performance, the flame proof seat ring adopts metal material, both play effect explosion-proof, conductor, guaranteed intensity again.The body and function Melamine plastics die casting of chamber, small electric bulb chamber is made, and also has certain intensity.Like this, as long as the intensity of transparent panel is enough,, also can not influence the explosion-proof performance of flashlight even in the flame proof cavity, produce slight blast.
The explosion-proof flashlight that the utility model provides, general structure is the intrinsically safe type blast resistance construction, key position is the flame-proof type structure, has reliable explosion-proof performance, the explosion-proof HB II 3e that is masked as, in environment temperature is-40～40 ℃, and relative humidity is not more than under 85% the condition and can uses safely in any explosive atmosphere except that containing oxygen, acetylene and carbon disulfide.
What accompanying drawing was described thes contents are as follows:
