Abstract
The utility model discloses a kind of spraying system of fire fighting shower nozzle connecting tube; tube body and protective layer are connected including shower nozzle; the shower nozzle connection tube body includes narrow end mouth, body and wide port; the internal diameter of said narrow end mouth is less than internal diameter of tube body; the inner surface of said narrow end mouth is provided with internal thread; the internal diameter of the wide port is identical with internal diameter of tube body, and the outer surface of the wide port is provided with an external screw thread；The internal thread and external screw thread are connected tube body with shower nozzle and are formed in one structure, and the protective layer includes the zinc coat for being arranged on the hot-dip coated and outer surface of tube body of outer surface of tube body.Its feature is：It is easy to connect shower nozzle and pipeline, inside and outside dual protects its resistance to corrosion of increase, increases the service life length.
Description
Technical field
The utility model belongs to pipe fitting technical field, more particularly, to a kind of spraying system of fire fighting shower nozzle connecting tube.
Background technology
It is the top for first a both ends being carried externally threaded straight pipe when existing spraying system of fire fighting is connected with shower nozzle
End connects shower nozzle again after being connected with a concentric reducer, and the bottom of straight pipe is connected in the threeway that spray system is responsible for, during dismounting, work
Part is more, process trouble, adds work difficulty to workmen, adds production cost, reduce operating efficiency, and fire-fighting
Contain certain impurity with water, easily connecting tube is caused to corrode, it is therefore necessary to improved.
The content of the invention
The purpose of this utility model is to be directed to above-mentioned the shortcomings of the prior art, there is provided a kind of spraying system of fire fighting spray
Head connecting tube, it is easy to connect shower nozzle and pipeline, inside and outside dual protects its resistance to corrosion of increase, increase the service life long spy
Point.
To achieve these goals, technical scheme is used by the utility model：A kind of spraying system of fire fighting shower nozzle
Connecting tube, including shower nozzle connection tube body and protective layer, the shower nozzle connection tube body include narrow end mouth, body and wide port,
The internal diameter of said narrow end mouth is less than internal diameter of tube body, and the inner surface of said narrow end mouth is provided with internal thread, the internal diameter of the wide port with
Internal diameter of tube body is identical, and the outer surface of the wide port is provided with an external screw thread；The internal thread and external screw thread and shower nozzle connecting tube sheet
Body is formed in one structure, and the protective layer includes the zinc-plated of the hot-dip coated and outer surface of tube body for being arranged on outer surface of tube body
Layer.
Further, said narrow end mouth extrudes to form round and smooth sagittal curvature with body junction.
Further, the shower nozzle connection tube body is made up of stainless steel.
After said structure, the utility model is compared to the prior art advantageously：The utility model shower nozzle
Connecting tube connects tube body by the shower nozzle including narrow end mouth, body and wide port and protective layer is formed, and in narrow end mouth
Surface and the outer surface of wide port are provided with screw thread, are easy to be connected with shower nozzle and pipeline；Wherein internal thread and external screw thread connect with shower nozzle
The adapter body structure that is formed in one not only has saved cost but also has avoided that is produced when working long hours as peripheral hardware screw thread
Raw displacement and situation about loosening.Wherein protective layer includes the zinc-plated of the hot-dip coated and outer surface of tube body for being arranged on outer surface of tube body
Layer, protected using this inside and outside dual, preferably increase its resistance to corrosion, increase the service life.Wherein narrow end mouth and body
Junction extrudes to form round and smooth sagittal curvature, more beautiful.Wherein shower nozzle connection tube body is made up of stainless steel.It is wherein narrow
The inner of port provided with sealing ring cause it is even closer be connected with shower nozzle, prevent leaked liquid.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model
Enclose, the utility model is further illustrated with reference to the accompanying drawings and examples.
Embodiment, as shown in Figure 1：A kind of spraying system of fire fighting shower nozzle connecting tube, including shower nozzle connection tube body and guarantor
Sheath, wherein shower nozzle connection tube body include narrow end mouth 10, body 20 and wide port 30, and the wherein internal diameter of narrow end mouth 10 is less than pipe
The internal diameter of body 20, it is connected in the case where the inner surface of narrow end mouth 10 ensure that not by additional means provided with internal thread with shower nozzle.
Wherein the internal diameter of wide port 30 is identical with the internal diameter of body 20, is used for connecting tube provided with an external screw thread in the outer surface of wide port 30
Road；Wherein internal thread and external screw thread are connected the tube body structure that is formed in one with shower nozzle and have not only saved cost but also avoided picture
Peripheral hardware screw thread that produced when working long hours displacement and loosen situation.Wherein protective layer includes being arranged on the appearance of body 20
The zinc coat of the outer surface of hot-dip coated and body 20 in face, protected using this inside and outside dual, preferably increase its anticorrosive energy
Power, increase the service life.Wherein narrow end mouth 10 extrudes to form round and smooth sagittal curvature with the junction of body 20, more beautiful.
Wherein shower nozzle connection tube body is made up of stainless steel.Wherein the inner of narrow end mouth 10 causes even closer with spray provided with sealing ring
Head is connected, and prevents leaked liquid.
