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.
Common Materials
Stainless Steel, Brass, Ceramic
Technical Parameters
  • Orifice diameter determining flow capacity and droplet size (mm) Per Request
Components / BOM
  • Nozzle Body
    Main housing containing flow channels and mounting interface
    Material: Stainless Steel
  • Orifice Plate
    Creates precise opening for liquid flow control
    Material: Hardened Steel or Ceramic
  • Valve Stem/Actuator
    Mechanism for opening/closing flow path
    Material: Stainless Steel
  • Seals/Gaskets
    Prevent leakage at connections
    Material: PTFE or Viton
Engineering Reasoning
3.5-25.0 bar (50-362.5 psi)
28.5 bar (413.25 psi) internal pressure differential
Design Rationale: Cavitation-induced erosion at vapor pressure differential exceeding 0.85 bar (12.3 psi) between inlet and throat, combined with thermal fatigue from 150-350°C cyclic temperature gradients at 0.5 Hz frequency
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding 15 μm diameter at 100 ppm concentration
Mode: Seat erosion leading to 0.15 mm³/s leakage rate at 10 bar
Strategy: Dual-stage filtration with 5 μm absolute rating and magnetic trap for ferrous particles
Trigger Solenoid coil insulation breakdown at 180°C continuous operation
Mode: Valve sticking with 2.5 N·m actuation torque exceeding design limit
Strategy: Class H (180°C) insulation with PTFE coating and thermal derating to 80% duty cycle above 150°C
