Abstract
A butterfly type heat-absorbing explosive door comprises an outer casing, a heat absorbing plate, a sealing valve, a butterfly spring, a guide device, a pressure regulator and a locker. The guide device is mounted in the outer casing, the sealing valve, the butterfly spring and the pressure regulator are sequentially mounted on the guide device, the locker is mounted on the pressure regulator, and the heat absorbing plate is mounted on the outer casing. The butterfly type heat-absorbing explosive door is fine in return effect, compact in structure, small in occupied space, stable in pressure, fine and reliable in sealing property, fine in safety and wide in applicable range. The sealing valve can return in time accurately, can not be eccentric and guarantees reliable operation of the explosive door. The pressure regulator arranged in the explosive door can be used for regulating pressure according to different occasions, so that the explosive door can be applicable to different occasions. The explosive door is provided with a gas engine which is stable in running, and then the explosive door is convenient in use, low in cost and the like. The explosive door is applicable to the field of gas engines.
Description
One, technical field
The utility model relates to the gas engine field, particularly a kind of butterfly heat absorbing type explosion proof door.
Two, background technique
At present, be that the gas engine of fuel has obtained developing rapidly with various inflammable gass.Yet gas engine in use but exists following shortcoming or deficiency: 1. the suction tude tempering phenomenon is more common, and it produces very big influence to the proper functioning of gas engine; When 2. tempering is serious even burst suction tude, cause security incident; 3. traditional explosion proof door does not have heat sink, and the tempering high temperature gas flow is directly discharged, easy breaking out of fire accident, and also Sealing easily lost efficacy; 4. traditional explosion proof door adopts the steel wire helical spring, and very fast inefficacy under the effect of tempering high temperature gas flow just can be opened under the very low situation of suction press, does not satisfy the normal service condition of motor, influences engine performance.
Three, summary of the invention
The purpose of this utility model provides a kind of butterfly heat absorbing type explosion proof door; adopt multi-disc butterfly spring and seal valve composite structure; be installed on the gas engine suction tude; seal valve can be opened rapidly when the air inlet tempering; suction tude is communicated with atmosphere; release the hot gas pressure of rapid rising; absorbing heat cooling back safety through endothermic plate discharges; seal valve is replied sealing state under the butterfly spring effect; thereby protection suction tude; guarantee normal working of engine, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Butterfly heat absorbing type explosion proof door described in the utility model comprises frame, endothermic plate, seal valve, butterfly spring, guiding device, pressure regulator and locker.Described guiding device is installed in the frame, and seal valve, butterfly spring, pressure regulator are installed on the guiding device in turn, and locker is installed on the pressure regulator, and endothermic plate is installed on the frame.
Wherein, the axle of described guiding device is installed on the frame middle part, and an end of axle passes frame, and the other end is installed in the pressure regulator.Described endothermic plate is installed on the excircle of locker.Described butterfly spring is the multidisc butterfly structure, is installed on continuously between the seal valve and pressure regulator on the axle.
The utility model has following advantage compared with prior art:
1, return better function adopts butterfly spring, can guarantee that gas engine turns round superior performance continuously at return after hours.
2, compact structure, it is little to take up space, gas engine claimed structure compactness, explosion proof door can not take very big space, therefore adopts the multi-disc butterfly spring, reduces the contour structure size of explosion proof door.
3, good reliability when gas engine runs well, seals by pretightening force of butterfly spring and sealing material, keeps the pressure in the suction tude steady, and during with the fluctuation of assurance suction tude internal air pressure, explosion vents seal is good, reliable.
4, designed guiding device on explosion proof door, explosion proof door work finishes, and during the seal valve return, can get back to sealing station timely and accurately, off-centre do not occur, prevents to lose sealability, guarantees the explosion proof door reliably working.
5. Safety performance is good, is provided with endothermic plate in explosion proof door, to the hot air flow discharging of can lowering the temperature, and phenomenon such as can not cause scald, catch fire.
6. applied widely, be provided with pressure regulator, can carry out pressure according to different occasions and regulate, satisfy different occasions and be suitable for.
7, gas engine is stable, and is simple in structure, easy to use, reliable, with low cost.
Four, description of drawings
Accompanying drawing is a kind of example structure schematic representation of the present utility model
Five, embodiment
Consult accompanying drawing, a kind of butterfly heat absorbing type explosion proof door comprises frame 1, endothermic plate 2, seal valve 3, butterfly spring 4, guiding device 5, pressure regulator 6 and locker 7.Guiding device 5 is installed in the frame 1, and seal valve 3, butterfly spring 4, pressure regulator 6 are installed on the guiding device in turn, and locker 7 is installed on the pressure regulator 6, and endothermic plate 2 is installed on the frame 1.
The axle of guiding device 5 is installed on frame 1 middle part, and an end of axle passes frame 1, and the other end is installed in the pressure regulator 6.Butterfly spring 4 is the multidisc butterfly structure, is installed on continuously between the seal valve 3 and pressure regulator 6 on the axle.
During operation, frame 1 of the present utility model is installed on the suction tude of gas engine, when gas engine ran well, the open and close of seal valve 3 was by 4 groups of controls of butterfly spring, and under the active force of butterfly spring 4, seal valve 3 seals with frame 1.When suction tude back draft, the pressurized gas of generation are pushed seal valve 3 open, make the suction tude inner chamber identical with atmosphere logical, and high pressure-temperature gas passes through endothermic plate 2 again by seal valve 3, and the cryogenic gas after the heat radiation enters in the atmosphere, reaches the purpose of rushing down pressure.After pressure was reduced to regulation numerical value, seal valve 3 is return under the effect of butterfly spring 4, cut off the passage that suction tude links to each other with atmosphere, and suction press recovers steadily, and gas engine still can remain in operation.The pressure of butterfly spring 4 can be regulated by pressure regulator 6, has regulated the back and has fixed with locker, keeps setting value constant, can satisfy the needs of different gas engines.Guiding device play the guiding role when the utility model is worked.
