Abstract
The utility model relates to a self-resetting explosion venting device which is characterized by comprising a base, a rubber sealing ring, a cover, guide screws, a positioning pressure plate, sleeve nuts and a spring. The base is fixed to equipment or a gas pipeline, a concentric circular groove is formed in the base, the rubber sealing ring is inlaid in the concentric circular groove, and the guide screws are fixed onto the base; the cover is sleeved on the guide screws via guide limiting holes which are formed in the cover by means of welding, and an edge opening of the cover is seated on the rubber sealing ring; the positioning pressure plate is sleeved on the upper portions of the guide screws, and the spring is arranged between the positioning pressure plate and the cover; the sleeve nuts are arranged at the uppermost ends of the guide screws. The self-resetting explosion venting device has the advantages that the pressure can be quickly relieved when the local combustion pressure of gas in the equipment and the pipeline is increased, so that the equipment and the pipeline are protected from being damaged; the explosion venting device is quickly closed when the pressure is reduced, so that external gas is prevented from being sucked into the equipment and the pipeline; manual operation is omitted in the automatic integral procedure.
Description
Technical field
The utility model relates to a kind of from resetting explosion venting device.
Background technique
The conveyance conduit of flammable explosive gas such as coal gas of converter, blast furnace gas or the flameproof apparatus on the equipment had membrane type explosion-released valve and heavy hammer type explosion-released valve in the past.The membrane type explosion-released valve is operated very inconvenient and influence production at the diaphragm that needs behind the venting of dust explosion on each off-line replacing explosion-released valve.The heavy hammer type explosion-released valve easily produces deviation when venting of dust explosion rear valve body return, poorly sealed, flammable explosive gas leaks.
The model utility content
The technical problems to be solved in the utility model provides a kind of from resetting explosion venting device, to overcome the defective that exists in the prior art.
The technical solution of the utility model is: a kind of from resetting explosion venting device, it is characterized in that: comprise pedestal, rubber seal, lid, guide spiro rod, positioning pressuring plate, threaded bush and spring; Wherein, pedestal is fixed on equipment or the gas pipeline, has concentric groove on the pedestal, and embedded rubber seal fixedly has guide spiro rod on the pedestal; By being welded in the guide and limit hole that covers, lid is enclosed within on the guide spiro rod, the bead of lid is sitting on the rubber seal; Positioning pressuring plate is enclosed within guide spiro rod top, and spring is arranged between positioning pressuring plate and the lid; The threaded bush is arranged at guide spiro rod topmost.
Described spring is band steel pagoda shape spring.
Described pedestal is round base.
Technique effect of the present utility model is: this explosion venting device is applicable on the deduster of flammable explosive gas such as coal gas of converter, blast furnace gas and on the pipeline.It act as: the part takes place when firing increased pressure in coal gas in equipment and pipeline, the rapid pressure release of explosion venting device is not damaged with protection equipment and pipeline; Simultaneously, explosion venting device is closed rapidly when pressure reduces, in case extraneous gas sucks.Whole process is carried out automatically, does not need manual operation.
The working pressure of this explosion venting device generally is set at 3000-3600Pa, and venting of dust explosion pressure generally is set at 4000-4600Pa.When the explosion venting device pressure-bearing was set venting of dust explosion pressure above self, explosion venting device was opened under pressure, rapidly venting of dust explosion; When explosion venting device pressure-bearing during less than self venting of dust explosion pressure, explosion venting device is closed automatically, recovers normal working.In addition, this device venting of dust explosion pressure can be adjusted according to the height of working pressure, and is very convenient.
Guide spiro rod has been determined the relative position of rubber seal, lid on the round base.By the preload pressure of threaded bush's adjustable cap and seal ring, namely determine the venting of dust explosion pressure of equipment by the elastic force size of regulating band steel pagoda shape spring.
Description of drawings
Fig. 1 is the sectional drawing from the explosion venting device that resets.
Fig. 2 is the plan view from the explosion venting device that resets.
Reference character is:
The bead of 1-pedestal, 2-rubber seal, 3-lid, 4-guide spiro rod, 5-positioning pressuring plate, 6-threaded bush, 7-band steel pagoda shape spring, 8-spacing hole, 9-lid.
Embodiment
Explosion venting device when the utility model equipment fires for inflammable gass such as converter gas recovery system, chemical industry.
Referring to Fig. 1 and Fig. 2, a kind of concrete structure from the explosion venting device that resets that the utility model relates to is:
Comprise pedestal 1, rubber seal 2, lid 3, guide spiro rod 4, positioning pressuring plate 5, threaded bush 6 and spring 7; Wherein, pedestal 1 is fixed on equipment or the gas pipeline, has concentric groove on the pedestal 1, and embedded rubber seal 2 fixedly has guide spiro rod 4 on the pedestal 1; By being welded in the guide and limit hole of covering on 38, will covering 3 and be enclosed within on the guide spiro rod 4, and can slide at guide spiro rod 4, and accurately the bead 9 that covers will be sitting on the rubber seal 2 that is embedded on the pedestal 1; Positioning pressuring plate 5 is enclosed within guide spiro rod 4 tops, and in order to pressing spring 7, spring 7 is arranged at the central position between positioning pressuring plate 5 and the lid 3; Threaded bush 6 is contained in guide spiro rod 4 topmost, and by pretension threaded bush 6, compressing positioning pressuring plate 5 compresses the extending amount of adjusting spring 7, covers 3 pressure to set.
Spring 7 in the utility model specifically can be band steel pagoda shape spring.According to the characteristic of this spring, when stressed, can compress rapidly, namely cover 3 and be opened to desired location rapidly, and play buffer function, when stressed disappearance, can restore to the original state rapidly, namely cover 3 and close rapidly, suck to prevent gas.Simultaneously can bear bigger load at less compression volume, relative volume is less.
Pedestal 1 in the utility model specifically can be round base.The explosion venting area of equipment is directly proportional with the volume of equipment, and under the condition with homalographic, round base is easily processed, resistance to deformation.
Working method of the present utility model is:
Regulating sleeve nut 6 makes 7 compressions of band steel pagoda shape spring, and under the effect of band steel pagoda shape spring 7, the bead 9 of lid contacts with rubber seal 2.Set working pressure when following when the gas pressure of internal system at explosion venting device, the bead 9 of lid keeps tightly contacting with rubber seal 4, and intrasystem gas does not outwards discharge at this moment; The working pressure that is higher than the explosion venting device setting when the gas pressure of internal system, when meeting or exceeding venting of dust explosion pressure, band steel pagoda shape spring 7 is compressed, this moment, the bead 9 of lid tightly contacted with seal ring 2 disengagings, moment opens, intrasystem gas is discharged with the gap location of seal ring 2 from the bead 9 of lid, reduces internal system pressure rapidly; When the gas pressure of internal system was lower than venting of dust explosion pressure, lid 3 was under the effect of band steel pagoda shape spring 7, and bead 9 and the seal ring 2 of lid are closed rapidly, and tight contact automatically resets.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not narration one by one.
