A flange is directly welded on a straight pipe and then is bent to form arc-shaped pipe sections, the arc-shaped pipe sections are connected through the flange to form an annular pipe, a spherical sealing body is installed in the flange, and guide pipes are arranged at two ends of the spherical sealing body. A spray head interface is arranged on the annular pipe and arranged on the inner side of the annular pipe, the inner side pipe wall is provided with holes, the pipe walls on the inner sides of the holes are provided with inner protrusions, outer protrusions are arranged on the pipe wall of the outer sides of the holes, and screws for installing a spray head are arranged in the holes between the inner protrusions and the outer protrusions. The fire-fighting sprinkler cooling protection device adopts the spherical sealing body to seal the flange and is good in sealing performance and convenient to install. The spray head interface provided with the inner and outer protrusions is connected with the spray head, connection is convenient, the sealing performance is good, a structure is firm, and dismounting and maintenance are facilitated. The fire-fighting sprinkler cooling protection device is suitable for a water spraying device for temperature reduction of a flammable and explosive storage tank.
Description
Technical field
The utility model provides the heat sink for inflammable and explosive oil gas and chemicals storage tank, specifically fire-fighting spraying Cooling protector.
Background technology
When the explosive storage tank stores oil product of inflammable storage tank or flammable and explosive substance, temperature raises can cause stored substance combustion or blast, causes security incident.Raise by environment temperature or solar radiation temperature for tank temperature, conventionally adopt the mode of spray cooling to solve.Conventional spraying temp. lowering apparatus structure is that on the annular water pipe connecting at flange, multiple shower nozzles are welded at interval, is sprayed water or is stopped water spray by water valve control.The shortcoming that the spraying temp. lowering apparatus of this structure exists is, flange connects arc pipeline, processing and enclose curved difficulty, flange is easily subject to the impact of expanding with heat and contract with cold, and causes leakage, can not spray water according to tank temperature in addition, moreover the straight chamber of shower nozzle water spray, current are subject to the impact of shower nozzle runner, and the water spray uniformity is poor, so it is unbalanced to lower the temperature.Therefore process and use inconvenience, cost is high, water spray weak effect.
Summary of the invention
The shortcoming existing in order to overcome existing spraying temp. lowering apparatus, the utility model provides fire-fighting spraying Cooling protector.This device, by adopting spherical sealing element and flange to connect and compose ring pipe on arc pipeline section, by the spray-head interface mounting spray head of internal projection and outer lug and hole formation, solves the technical problem of inflammable and explosive storage tank spraying temp. lowering apparatus structure in ring pipe inboard.
The scheme that the utility model technical solution problem adopts is:
On straight tube, bending formation arc pipeline section after welded flange connects by flange between arc pipeline section, and looping pipe is equipped with spherical seal in flange, and the two ends of spherical seal are provided with guiding tube;
On ring pipe, be provided with spray-head interface, spray-head interface is located at the inner side of ring pipe, on the tube wall of inner side, is provided with hole, and the tube wall of inboard, hole is provided with internal projection, outside hole, tube wall is provided with outer lug, is provided with the spiral shell button for mounting spray head in the hole between internal projection and outer lug.
Good effect, the utility model adopts spherical seal sealing flange, good seal performance, and be convenient to install; In adopting, the spray-head interface of outer lug connects shower nozzle, easy to connect, good seal performance, and sound construction, and be convenient to dismounting and maintenance.The suitable water injector as inflammable and explosive cooling storage tank uses.

Detailed description of the invention
According to the figure, on straight tube, bending formation arc pipeline section after welded flange connects by flange 2 between arc pipeline section, and looping pipe 1 is equipped with spherical seal 2.1 in flange, and the two ends of spherical seal are provided with guiding tube 2.2;
On ring pipe, be provided with spray-head interface, spray-head interface is located at the inner side of ring pipe, on the tube wall of inner side, is provided with hole, and the tube wall of inboard, hole is provided with internal projection 1.1, outside hole, tube wall is provided with outer lug 1.2, is provided with the spiral shell button 1.3 for mounting spray head in the hole between internal projection and outer lug.
Assembling of the present utility model:
Multistage arc pipeline section is connected with spherical seal by flange, and looping pipe by spiral shell button mounting spray head, forms spraying temp. lowering apparatus on ring pipe.
Use of the present utility model:
Ring pipe is communicated with feed pipe, and the water in feed pipe carries out equilibrium by ring pipe and distributes, from each shower nozzle ejection, to tank body ring Zhou Jinhang spray cooling.
Feature of the present utility model:
1, use spherical seal sealing, can realize the sealing of pipeline section decentraction, institute is so that install seal between flange, compared with traditional rubber gasket, good seal performance, long service life is installed easily.
2, the spray-head interface that adopts internal projection and outer lug, screw thread contact-making surface valency is large, and long, so shower nozzle is installed firmly, compared with traditional tube wall straight hole spray-head interface, shower nozzle is convenient to install with fixing, therefore service life is also long.
