The ventilation cap is simple in structure, low in manufacturing cost and simple and convenient to repair. A fire retardance corrugated plate is used for exhausting air in a storage device and feeding air into the storage device, all combustion sources are blocked and eliminated, safety of an oil tank is guaranteed, explosion is avoided, and safety guarantee is provided for oil storage.
Description
Technical field
The present invention relates to a kind of Ventilated cap, especially relate to a kind of Ventilated cap with back-fire relief function, is to guarantee the ventilative safe important corollary equipments such as petrol service station, oil tank.
Background technology
Oil, also claims crude oil, be a kind of thickness, chocolate (sometimes a little green) liquid.There is oil storage upper crustal some areas.Stone oil properties is different because of the place of production, and density is 0.8 ~ 1.0 grams per cubic centimter, and range of viscosities is very wide, solidfying point difference very large (30-60 degree Celsius), boiling spread is more than normal temperature to 500 degree Celsius, dissolves in multiple organic solvent, water insoluble, but can form emulsion with water.But the composition of the oil in different oil fields and appearance can be distinguished very large.Oil is mainly used as fuel oil and gasoline, and bunker oil and gasoline form at present one of most important primary energy in the world.Oil is also that many chemical frbre industry products are as the raw material of solvent, chemical fertilizer, insecticide and plastics etc.Today, the oil of 88% exploitation was used as fuel, other 12% raw material as chemical industry.Because oil is a kind of non-renewable raw material, many people worry the consequence of always mankind being brought for oil.Research shows, the generation of oil at least needs the time of 2,000,000 years, and in the oil reservoir of having found now, the time is the oldest reaches 500,000,000 years.In the long history process constantly developing at the earth, there is " special " period, as Paleozoic and Mesozoic Period, after a large amount of plant and animal death, the organic substance that forms its health constantly decomposes, and mixes and forms sedimentary deposit with the material such as silt or carbonic acid matter accretion.Because sediment is constantly piled up thickening, cause temperature and pressure to rise, along with constantly carrying out of this process, sedimentary deposit becomes sedimentary rock, and then forms depositional basin, and this is just for the generation of oil provides basic geologic environment.The composition of crude oil mainly contains: oil (this is its main component), colloid (a kind of semi-solid material of viscosity), asphaltene (dun or black brittle solid material), carbonaceous (a kind of nonhydrocarbon).Oil is main mixing by hydro-carbon, has comb. oily liquid special odor, coloured! Natural fuels is to take the hydro-carbon of gaseous state to be main various gas compositions, has comb. miscellaneous gas special odor, colourless.In whole petroleum system, the division of labor is also thinner: form the chemical substance of oil, with distillation, can decompose.Crude oil, as the product of processing, has kerosene, benzene, gasoline, paraffin, pitch etc.Strictly speaking, it is main component that oil be take the hydro carbons that hydrogen and carbon forms, and 4 kinds of hydrocarbon of mol wt minimum, are all coal gas.The materials such as gasoline after oil refining, have just been obtained, gasoline is the energy of various Vehicle Driving Cycles, in petrol service station or oil storage region, especially in gasoline storage device, be mixed with a certain amount of gas, when running into naked light or high temperature, easily produce blast, cause great safety misadventure, so the protection in equipment or region is all the most important thing.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art; a kind of Ventilated cap with back-fire relief function is provided; this Ventilated cap is simple in structure; low cost of manufacture, keeps in repair easyly, utilizes fire-retardant core corrugated plating to carry out exhaust and air inlet to the gas in storage device; stop and stop all burning things which may cause a fire disaster and pass through; the safety of protection oil tank, prevent exploding, provides safety control to the storage of oil plant etc.
Object of the present invention is achieved through the following technical solutions: have the Ventilated cap of back-fire relief function, comprise supporting seat, the center of described supporting seat is provided with back-fire relief plug, and crown cap is set on described supporting seat, and it is inner that one end of described supporting seat is arranged on top cap.
Between described top cap and supporting seat, be provided with bolt, described bolt is connected with supporting seat with top cap simultaneously.
The quantity of described bolt is three, and is evenly arranged between top cap and supporting seat.
The center of described supporting seat is provided with through hole, and described back-fire relief plug is arranged in through hole.
In described back-fire relief plug, be provided with fire-retardant core.
The bottom of described supporting seat is provided with installation ring, the parallel contact in bottom of described installation ring and supporting seat.
On described installation ring, be provided with some tapped bore, described tapped bore is evenly arranged on installation ring.
In sum; the invention has the beneficial effects as follows: this Ventilated cap is simple in structure; low cost of manufacture; keep in repair easy; utilize fire-retardant core corrugated plating to carry out exhaust and air inlet to the gas in storage device, stop and stop all burning things which may cause a fire disaster and pass through, the safety of protection oil tank; prevent exploding, provides safety control to storage of oil plant etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark and corresponding parts title in accompanying drawing: 1-installation ring; 2-tapped bore; 3-supporting seat; 4-back-fire relief plug; 5-top cap; 6-bolt.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
As shown in Figure 1, have the Ventilated cap of back-fire relief function, comprise supporting seat 3, the center of described supporting seat 3 is provided with back-fire relief plug 4, and crown cap 5 is set on described supporting seat 3, and one end of described supporting seat 3 is arranged on top cap 5 inside.Between top cap 5 and supporting seat 3, have certain gap, facilitate the turnover of air, burning things which may cause a fire disaster is difficult for entering into top cap 5 inside simultaneously, has increased safety factor.
Between described top cap 5 and supporting seat 3, be provided with bolt 6, described bolt 6 is connected with supporting seat 3 with top cap 5 simultaneously.
The quantity of described bolt 6 is three, and is evenly arranged between top cap 5 and supporting seat 3.By bolt 6, realize fixing between top cap 5 and supporting seat 3, convenient when handling, reduced maintainer's labour intensity.
The center of described supporting seat 3 is provided with through hole, and described back-fire relief plug 4 is arranged in through hole.Through hole is as the passage of air-flow turnover.
In described back-fire relief plug 4, be provided with fire-retardant core.Fire-retardant core adopts stainless steel wave card to make, when the expansion of oil tank material or oil-feed, by the outside exhaust of corrugated plating of fire-retardant core.In oil tank, outwards drain the oil and when air-breathing in tank, the entering of the isolated burning things which may cause a fire disaster of corrugated plating by fire-retardant core.
The bottom of described supporting seat 3 is provided with installation ring 1, the parallel contact in bottom of described installation ring 1 and supporting seat 3.By installation ring 1 is set, strengthen the area of contact of supporting seat 3 and oil tank, to install more conveniently, fixed effect is better.
