Abstract
A firefighting water spraying device for a dome roof tank consists of a spray head, a water pipe, a sealing ring and a dome roof tank, wherein, the water pipe is arranged on the dome roof tank and is connected with the spray head; a plurality of spray holes facing downwards slantwise are uniformly distributed on the spray head and form a 50 to 80 DEG angle with the axial line of the spray head; and the sealing ring is arranged at the joint of the water pipe and the spray head. A breather valve can be covered by water curtain formed during spraying water so as to prevent mixing of oil gas in the tank with the air, thereby preventing the occurrence of fire. The water is sprayed uniformly around and naturally flows from top to bottom without blank so as to uniformly lower the temperature. Accordingly, the firefighting water spraying device can rapidly and uniformly spray the dome roof tank to lower the temperature and ensure the safety of oil stations.
Description
Technical field:
The utility model is the fire plant on the oil storage tank of oil field, particularly a kind of arch-roof tank fire water spray equipment.
Background technology:
At present each central gathering station mostly is the middle-size and small-size vault storage tank of 2000-5000m3, uses artificial hand-held hydraulic giant jetting formula spraying cooling mode always, and the problem that this mode exists has: the one, and distance, hydraulic giant range are not enough; The 2nd, single hydraulic giant film-cooled heat is little, needs many hydraulic giants to cooperate; The 3rd, it is inhomogeneous to spray water, and white space occurs, causes local heating, and it is inhomogeneous to lower the temperature; The 4th, be subjected to ambient wind big to influencing, be not easy to be ejected on the storage tank.
Summary of the invention:
The purpose of this utility model is a kind of arch-roof tank fire water spray equipment of design, make its can to the vault storage tank fast, even spraying cooling, guarantee oil station safety.
The purpose of this utility model has been achieved in that the vault storage tank, on the vault storage tank water-supply-pipe is installed, and water-supply-pipe connects with spray head, and a plurality of spray orifices of oblique below are arranged on the spray head, and spray orifice circumference on the pouring head evenly distributes.
The axis angle of spray orifice and spray head is 50 °-80 °.
On the described arch-roof tank fire water spray equipment sealing ring is arranged, described sealing ring is in water-supply-pipe and spray head connection place.
The beneficial effects of the utility model are: the cascade that forms during water spray covers breather valve, stops jar interior oil gas to mix with air, can not cause fire, and the water of ejection trickles from top to bottom naturally toward evenly spraying all around, does not blank lowering temperature uniform.Therefore, the utility model can to the vault storage tank fast, even spraying cooling, guarantee oil station safety.
Description of drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Embodiment of the present utility model is made up of spray head 1, water-supply-pipe 4, sealing ring 3, vault storage tank 5, water-supply-pipe 4 is installed on vault storage tank 5, water-supply-pipe 4 connects with spray head 1, and a plurality of spray orifices 2 of oblique below are arranged on the spray head 1, and circumference evenly distributes spray orifice 2 on 1 drenching.Spray orifice 2 is 60 ° with the axis angle of spray head 1, oblique below spray.Sealing ring 3 is in water-supply-pipe 4 and spray head 1 connection place, and water under high pressure can only be sprayed from spray orifice 2.Water-supply-pipe 4 other ends connect with water supply valve on ground, open water supply valve during spray and just can spray, therefore, reaction only needs about 3 minutes from whole coverings of spraying water fast, and the fire fighter can be away from vault storage tank operation water spray, thereby safe and reliable, be safe from danger.
