Abstract
The utility model relates to explosion-proof apparatus, the water valve that comprises round iron cylinder, air inlet pipe, escape pipe, Explosion-proof cap offset plate, water-level gauge, connection water source, one side of described round iron cylinder arranges air inlet pipe, the opposite side of described round iron cylinder sets out tracheae, the upper surface of described round iron cylinder arranges Explosion-proof cap offset plate, the bottom of described round iron cylinder arranges water-level gauge, and the top of described round iron cylinder arranges water valve.The utility model utilizes water-cooled in round iron cylinder, isolated or hinder flame and further propagate; once blast in gas pipe or burn; because blast wave is completely cut off by flame or water seal; make Explosion-proof cap glue wash open or break simultaneously; explosion energy is discharged, thus protection ground or down-hole, draw-off pump station equipment and user security.
Description
Technical field
The utility model relates to a kind of back-fire relief explosion-proof apparatus, belongs to gas discharge in mine and chemical industry tail gas CIU technical field, is specifically related to a kind of water seal explosion-proof apparatus.
Background technology
Water seal explosion-proof apparatus is mounted in a kind of safety convenience instrument of the positive pressure side of releasing pipe, when gas drainage pipeline meets accident explosion accident, the shock wave that prevent exploding produces destroys drainage system, and the flame that blocking-up blast produces conducts along extraction pipeline, a kind of Special safety device that Accident prevention further expands, can select according to the size of different pipeline diameters the explosion-proof apparatus of different size.
Explosion-proof apparatus of the prior art, its structure is comparatively simple, only comprises air inlet pipeline, gas exhaust piping and explosion-proof vent, such water seal fire arrestor is because structure is simple and crude, poor controllability, Fire resistances is low, has very large potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, and provides a kind of and the object of the invention is in order to provide a kind of Fire resistances high, safe and reliable explosion-proof apparatus.
For achieving the above object, the explosion-proof apparatus of the utility model design, the water valve that comprises round iron cylinder, air inlet pipe, escape pipe, Explosion-proof cap offset plate, water-level gauge, connection water source, one side of described round iron cylinder arranges air inlet pipe, the opposite side of described round iron cylinder sets out tracheae, the upper surface of described round iron cylinder arranges Explosion-proof cap offset plate, and the bottom of described round iron cylinder arranges water-level gauge, and the top of described round iron cylinder arranges water valve.
The utility model utilizes water-cooled in round iron cylinder, isolated or hinder flame and further propagate; when its principle is mounted in the proper normal extraction of malleation; gas is drawn out of or is discharged by water seal face; once blast in gas pipe or burn, because blast wave is completely cut off by flame or water seal, make Explosion-proof cap glue wash open or break simultaneously; explosion energy is discharged; thereby protection ground or down-hole, draw-off pump station equipment and user security, Fire resistances is high, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: 1-round iron cylinder; 2-air inlet pipe; 3-escape pipe; 4-Explosion-proof cap offset plate; 5-water-level gauge; 6-water valve.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Explosion-proof apparatus as shown in Figure 1, the water valve 6 that comprises round iron cylinder 1, air inlet pipe 2, escape pipe 3, Explosion-proof cap offset plate 4, water-level gauge 5, connection water source, one side of round iron cylinder 1 arranges air inlet pipe 2, the arrival end of air inlet pipe 2 is connected with source of the gas, the opposite side of round iron cylinder 1 sets out tracheae 3, the upper surface of round iron cylinder 1 arranges Explosion-proof cap offset plate 4, and the bottom of round iron cylinder 1 arranges water-level gauge 5, and the top of round iron cylinder 1 arranges water valve 6.
While enabling explosion-proof apparatus, water level in round iron cylinder 1 is higher than air inlet pipe water seal face 50mm-80mm, when the water level of water-level gauge 5 indication is within the scope of this, close water valve 6, when the water level of water-level gauge 5 indication is not within the scope of this, open that water valve 6 adds water until water level reaches this scope, can not be too high, the too high water that causes overflows.
The content not being described in detail in this manual belongs to the known prior art of professional and technical personnel in the field.
