ABSTRACT:
A spray nozzle is disclosed for a sprinkler system in a corrosive or dirty environment. The spray nozzle of the present invention retains its operability over known types of spray nozzles, particularly when used in hot environments or in corrosive, dirty environments. The spray nozzle has a tubular body formed from heat resistant thermoplastic material with an inlet at one end and an outlet orifice at the other end. A plunger is provided formed from heat resistant thermoplastic material having a stem slidably mounted within the tubular body, the plunger having an enlarged head at one end of the stem located outside the tubular body and adjacent the outlet orifice, and a thermoplastic spring within the tubular body to normally bias the plunger stem in a direction toward the inlet to have the plunger head close the outlet orifice, the spring capable of being overcome by water under pressure entering the inlet of the tubular body, and acting on the plunger head from within the tubular body to move the plunger head away from the tubular body to open the outlet orifice.
