A nozzle is a precision component used to control the direction, flow rate and form of fluid (liquid, gas or gas-liquid mixture) injection, and is widely applied in industrial manufacturing, agricultural irrigation, environmental protection projects, medical equipment and other fields.
Nozzles come in various shapes depending on their uses. Common ones include:
Cylindrical: The fluid is sprayed in a straight line along the axis direction, suitable for scenarios such as flushing and cooling (such as high-pressure water guns).
Conical/fan-shaped: Through an internal flow diversion structure, the fluid is dispersed into conical or fan-shaped sprays, which are used for uniform spraying and humidification (such as agricultural sprayers, automotive painting nozzles).
Venturi type: It utilizes a contractional-expansion structure to accelerate the fluid, creating negative pressure to draw in gas and achieve gas-liquid mixing (such as in atomizing nozzles and burner nozzles).
Porous type: Multiple tiny spray holes are arranged to simultaneously generate multiple fine streams or droplets, enhancing coverage efficiency (such as in air conditioner humidifiers and diesel engine fuel injectors).
