Abstract
The utility model provides a fuel gas explosion-proof top device, comprising a box body, a fuel gas station, a clamping groove plate, a clamping nail, a fixed plate, an explosion-proof top plate, an air suction hole, an explosion-proof valve, an exhaust pipe, a bolt, a fixed nut, channel steel, and an opening pin. When fuel gas is leaked in the fuel gas station to generate certain pressure, the explosion-proof valve is opened automatically, and the fuel gas is directly discharged from the exhaust pipe; and if the explosion-proof valve can not be opened automatically owning to a failure, the internal pressure of an explosion-proof top is gradually increased, and the explosion-proof top plate is lifted up automatically, so that the fuel gas in the explosion-proof top is discharged from a clearance between the explosion-proof top plate and the box body, thus realizing dual safety for dealing with gas leakage. The fuel gas explosion-proof top device can be widely applied to the fuel gas stations of towns, novel residential districts, large factories and the like, manpower and material resources can be saved, a safe and reliable guard line is added for eliminating fuel gas accidents, the safety of life and possessions of users can be ensured, and the social and economical benefits are realized.
Description
Technical field
The utility model relates to a kind of anti-explosion fuel gas equipment, particularly anti-explosion fuel gas ejection device.
Background technique
Since China reform and opening-up, national economy is increased fast, has become the main flow of the present industrial development of China with " scientific and technical innovation, autonomous innovation ", and China's industry is progressively to intensive style, energy-saving and emission-reduction, and the direction of low-carbon (LC) develops.Along with the reform and opening-up and the continuous development of economic construction, living standards of the people improve day by day, and the fast development of novel residential quarters adds that " each city and each small towns are come in the enforcement of West-east Gas construction project, rock gas gradually.Natural gas can produce great pressure in storage and course of conveying, if these flammable combustion gas leak, run into thermal source in the air, causes burning easily, and serious meeting sets off an explosion, particularly gas station.In order to address this problem, R﹠D institution and science and technology in enterprise personnel utilize modern science and technology in constantly research, exploration, though obtained some progress technically, still exist the technical barrier that does not overcome as yet in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of anti-explosion fuel gas ejection device is provided, when combustion gas in the gas station takes place to reveal, produce certain pressure, explosion-proof valve will be opened automatically, combustion gas directly discharges from outlet pipe, if explosion-proof valve can't be opened automatically because of fault, explosion-proof top internal pressure increases gradually, the lifting that will make progress automatically of explosion-proof top board, combustion gas discharges by the gap location of explosion-proof top board and casing in the explosion-proof top, combustion gas is revealed realized double insurance.
The technological scheme that its technical problem that solves the utility model adopts is: comprise casing, gas station, the draw-in groove plate, bail, fixed plate, explosion-proof top board, intakeport, explosion-proof valve, outlet pipe, bolt, set screw nut, channel-section steel, cotter pin, the casing shape that is rectangle, be provided with gas station in the casing, upper end, both sides in the casing is provided with the draw-in groove plate, the draw-in groove plate shape that is rectangle, the center is provided with long slot, two screws on the draw-in groove plate firmly are connected explosion-proof top board with fixed plate with bolt, bail is located in the long slot in the draw-in groove plate, on bolt, be provided with eyenut, be provided with explosion-proof top board below the eyenut, be provided with set screw nut below the explosion-proof top board, bolt is connected with channel-section steel, bolt passes channel-section steel, be provided with a nut in the upper end of channel-section steel, be provided with a cotter pin at the bolt terminal position, be provided with an adjusting nut in the upper end of cotter pin, the lower end of explosion-proof valve is connected with the horn intakeport, intakeport is connected with center, upper end, explosion-proof top, the upper end of explosion-proof valve is connected with outlet pipe, has formed the anti-explosion fuel gas ejection device.
The know-why that the utility model adopted is: when the gas station combustion gas took place to reveal, the leakage combustion gas in the casing was to intakeport direction venting, and explosion-proof valve is subjected to the pressure of combustion gas and will opens automatically, and combustion gas is directly discharged from outlet pipe.Be provided with the damping spring structure in the explosion-proof valve, behind the damping spring pressurized, the valve of explosion-proof valve will be opened automatically.If explosion-proof valve can't be opened automatically because of fault; box house pressure increases gradually; gaseous-pressure is greater than explosion-proof top board self gravitation in casing; bail moves upward along the long slot straight line at draw-in groove plate center, and bolt and explosion-proof top board level simultaneously upwards promote, when below cotter pin rises to channel-section steel; explosion-proof top board will be fixed; combustion gas just discharges from the gap location of explosion-proof top board and casing like this, has protected facility in the gas station, prevents the generation of explosive accident.
The utility model beneficial effect is: a kind of anti-explosion fuel gas ejection device that can guarantee combustion gas storage or combustion gas delivery safety is provided, product structure is simple, novel, easy for installation, the combustion gas leakage has been realized double insurance, can be widely used in gas stations such as cities and towns and novel residential quarters, integrated mill, saved the human and material resources resource, add safe and reliable defence line one for getting rid of gas accidents hidden danger, guaranteed the people life property safety, brought social benefit and economic benefit.
