Abstract
The utility model relates to a fire retardant and explosion proof device of an automobile oil box pouring orifice, which is the device capable of preventing the automobile oil box pouring orifice from combusting and exploding. The utility model comprises an automobile oil box. The interior of the oil box is provided with an inverted conical framework, and the upper end of the framework is provided with an elastic collar which is supported on the inner wall of the oil box pouring orifice. The middle position in the framework is provided with an oil inlet conical pipe, and the exterior of the framework is connected with an inverted conical net body formed by encirclement of a metal net. The HAN fire retardant and explosion proof material is arranged between the framework and the metal net body. When a cover of the automobile oil box is opened, the mixing gas of the fuel in the oil box and the air can enter a honeycomb structure of the HAN fire retardant and explosion proof material, and thus, the utility model prevents quick spread of flame and instant release of energy and destroys burning conditions of the mixing gas. As a consequence, the utility model can prevent combustion and avoid explosion occurrence if the utility model suffers from open fire, static electricity, impact and other fortuitous events. Because the HAN safe explosion proof material can inhibit fuel volatilization, the utility model reduces friction of the volatilized fuel and the air, and thus, the static electricity can be eliminated.
Description
Technical field
The utility model relates to a kind of pouring orifice fire and explosion resistant device of vehicle fuel tank, it is the device that the pouring orifice of automotive oil tank is carried out flame-proof explosion-proof.
Background technology
Automotive oil tank mostly is located at the both sides of automobile rear.When fuel tank being refueled or fuel tank keeped in repair, in case the fuel tank tegmentum is opened, the big gauging, the oxygen mixture that store in the fuel tank just spray from oil filling orifice of fuel tank.As running into unforeseen circumstancess such as naked light, static, fuel tank is easy to cause burning and exploding car takes place that its consequence can not be imagined, this oil of while, gas mixture exhaust to atmosphere, contaminated environment at this moment for this oil, oxygen mixture.
The content of utility model
The purpose of this utility model provides a kind of pouring orifice fire and explosion resistant device of vehicle fuel tank, prevents the burning of fuel tank and sets off an explosion, and thoroughly solves the safety problem of automobile, reduces the pollution to atmosphere of oil, gas mixture simultaneously.
A kind of pouring orifice fire and explosion resistant device of vehicle fuel tank, include automotive oil tank, it is characterized in that being provided with in the automotive oil tank turbination skeleton, the skeleton upper end is an open-type, be provided with circlip in the opening annulus outside, circlip holds the inwall at oil filling orifice of fuel tank, is provided with O-ring seal between skeleton and the oil filling orifice of fuel tank.Be provided with the oil-feed Taper Pipe in intraskeletal middle part, the outside of skeleton connects the dictyosome that is surrounded by wire gauze, and HAN flame-proof explosion-proof material is housed between skeleton and the metal dictyosome.
The maximum gauge of skeleton upper end open annulus is less than the internal diameter of oil filling orifice of fuel tank.
Circlip is made by spring steel plate.
Skeleton is made by stainless steel wire.
The metal dictyosome is made by stainless steel cloth.

2. the oily fuel volatilization in the inhibition fuel tank reduces fuel consumption;
3. elimination static;
4. this apparatus structure is simple, and is easy for installation, is easy to safeguard.
Description of drawings
Accompanying drawing is a Figure of description of the present utility model.
Wherein: 1 automotive oil tank, 2 fuel lids, 3, metal dictyosome, 4HAN flame-proof explosion-proof material, 5 turbination skeletons, 6 O-ring seals, 7 circlips, 8 oil-feed Taper Pipes, 9 oil filling orifice of fuel tank.
The embodiment explanation
A kind of pouring orifice fire and explosion resistant device of vehicle fuel tank includes automotive oil tank 1, and the turbination skeleton of being made by stainless steel wire 5 is set in automotive oil tank 1.The circle of going up of skeleton 5 is open type, outside the opening annulus of skeleton 5, survey and be provided with circlip 7, circlip 7 is made by spring steel plate, circlip 7 holds on the inwall of automotive oil tank pouring orifice 9, because the maximum gauge of skeleton 5 upper end open annulus is less than the internal diameter of oil filling orifice of fuel tank 9, this hovers turbination skeleton 5 and can not come off in fuel tank.Be provided with O-ring seal 6 between skeleton 5 and the oil filling orifice of fuel tank 9, prevent that the fuel oil medium from volatilizing along pouring orifice 9 inwalls.Outside at skeleton 5 connects the obconic dictyosome 3 that is surrounded by wire gauze, and HAN flame-proof explosion-proof material 4 is housed between skeleton 5 and the metal dictyosome 3.Middle part in skeleton 5 is provided with oil-feed Taper Pipe 8.It is to surround osed top by stainless steel wire, and purpose is that the oil transportation ozzle at the oiling numerical control machine just is being inserted into oil-feed Taper Pipe 8.Surround obconic dictyosome 3 in the connection of the outside of HAN flame-proof explosion-proof material by the metal twine, can stop that the broken impurity of cutting of HAN flame-proof explosion-proof material falls in the fuel tank, guarantee the cleaning of fuel oil medium in the fuel tank.After the fuel oil medium is filled with, that fuel lid 2 lids are tight.
HAN flame-proof explosion-proof material 4 is netted or spherical special alloy material.This material is corrosion-resistant steel or aluminum alloy etc.
The HAN flame-proof explosion-proof material of installing in the skeleton of this device, the patent of invention-application number that is subordinate unit of our company is 92102437.1, its name is called " explosion-suppressing material that is used for explosives, inflammable items " (authorizing).The mechanism of HAN flame-proof explosion-proof material is fire-retardant, the anti-explosion product of developing according to the pacing factor that heat transfer theory and formation are burnt, exploded.In fuel tank, place HAN flame-proof explosion-proof material, can stop the burning of fuel oil medium and the generation of blast.Because the structure of HAN flame-proof explosion-proof material is a kind of honeycomb structure of high hole, it can stop the bamboo telegraph of flame and the abrupt release of energy, utilize the surface effect of material to absorb lot of energy, destroyed the explosion condition of combustion medium, thus the generation that stops burning and set off an explosion.
When the fuel lid 2 of automobile was opened, the fuel of assembling in the fuel tank and a large amount of miscellaneous gass of air at first entered in the honeycomb structure of HAN flame-proof explosion-proof material.Because the special mechanism of HAN safety anti-explosive material has stoped the bamboo telegraph of flame and the abrupt release of energy, destroyed the condition of miscellaneous gas burning, as unforeseen circumstancess such as naked light, static, stop the generation of blast.HAN flame-proof explosion-proof material can also suppress the fuel volatilization, reduces the combustion loss.
Because HAN flame-proof explosion-proof material can suppress the volatilization of fuel, thereby reduce the fuel and the friction of air of volatilization greatly, and HAN safety anti-explosive material has good electric conductivity, so this device has the effect of elimination static.
