Product Specifications

Technical details and manufacturing context for Liquid Injection Nozzle/Valve

Definition
The liquid injection nozzle/valve is a critical part of vaporizer/generator systems that precisely meters, atomizes, and directs liquid feed (such as water, fuel, or chemical solutions) into the vaporization chamber. It ensures proper mixing, distribution, and flow control for efficient phase change from liquid to vapor.
Working Principle
The nozzle/valve operates by controlling liquid flow through an orifice using mechanical, pneumatic, or hydraulic actuation. When opened, pressurized liquid passes through the nozzle where it may be atomized into fine droplets for rapid vaporization, with flow rate and spray pattern determined by nozzle design, pressure differential, and valve positioning.
