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. This component is designed for use in industrial machinery where controlled liquid delivery is essential. It operates within a specified pressure range of 1.0–1.6 MPa and can handle flow rates from 0.5 to 5.0 L/min, adjustable via a needle valve. The spray angle ranges from 60 to 120 degrees, producing a full cone pattern, and the droplet size, measured as Sauter mean diameter, is between 50 and 200 micrometers. The operating temperature range is -20 to 120 degrees Celsius, with seals degrading above 120°C. The body is typically made of stainless steel (316L), brass, or ceramic, offering corrosion resistance. Connections are threaded, sized 1/4 to 1/2 inch NPT, and the weight varies from 0.3 to 0.8 kg depending on connection size. The leakage rate at rated pressure is ≤0.01 mL/min per ISO 5208, and the response time from signal to full open is ≤50 ms. For solenoid actuation, the voltage is 24 V DC ±10%, with power consumption between 5 and 15 W (holding power lower than inrush). The enclosure rating is IP65, dust-tight and protected against water jets. All listed parameters are reference ranges that must be verified for the specific model and application. Always confirm model-specific values and standards with the legal manufacturer or supplier.
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. The valve can be adjusted to achieve the desired flow and spray characteristics, ensuring efficient mixing and vaporization.
