1. Introduction of Spiral Sprinkler
The spiral nozzle is a cone nozzle that can produce hollow cone and solid cone spray shapes, and the spray angle is 60°-170°. This compact can make the liquid reach the maximum flow rate on a pipe of a given size. Under a pressure of 3 bar, the flow rate rises from 5.5 to 4140 liters/min. Spiral sprinklers can be installed or updated on most piping systems. The nozzles available are NPT or BSPT (external) threaded type. Usually 1/4 inch to 4 inch nozzles can be made of brass, 316 stainless steel castings, TEFLON polytetrafluoroethylene or polyvinyl chloride materials. For higher pressures, brass and cast 316 stainless steel nozzles are required. If it needs to be used in special fields, it can also be made of other materials.
Spiral nozzle specifications
Second, the specifications of the spiral nozzle
The specification information of spiral sprinklers mainly includes thread interface size, shape, production material, angle, flow, connection method, and flow parameters of spiral sprinklers under different pressures, etc., generally composed of the following parts:
1/2-SPJT-316SS-120 120 (solid cone, BSPT interface standard)
1/2, which means the size of the interface of the spiral nozzle, 1/2 is the interface of 1/2 inch;
SPJT, is the English abbreviation of spiral nozzle, which represents the model of spiral nozzle;
316SS is the material code, and 316SS represents the stainless steel grade 316;
120, which means that the angle is 120 degrees;
120 is the flow rate representative, which represents the approximate flow rate of this nozzle under a certain pressure.
Spiral sprinklers are available in two cone types, so a solid cone means that the shape of this spiral sprinkler is a solid cone. BSPT is the standard for threaded connections, and the standard for imperial tapered pipe threads, in addition to the imperial BSPT American-made NPT thread standard. These are the specifications of the spiral nozzle
