Safety Breakaway Valve(M34X1.5)
Safety Breakaway Valve (M34×1.5 High-Pressure for Gas Station Dispensers)
Core Differentiation:Adopts a composite structure of aluminum alloy housing + stainless steel M34×1.5 thread component + fiber-reinforced plastic internal parts + PU/NBR seals with a preset breakaway force of 1200-1500N — breaking through the limitations of ordinary valves such as single material, poor thread adaptability, redundant/insufficient breakaway force. The M34×1.5 thread precisely matches gas station high-pressure pipelines, and the composite material achieves the synergistic advantages of lightweight corrosion resistance + strong connection wear resistance + seal anti-aging. The 1200-1500N breakaway force ensures reliable separation in dangerous situations and no accidental triggering in daily working conditions.
1. Performance Parameters
-Material System:
- Housing: Aluminum alloy (lightweight design, resistant to gasoline/diesel corrosion);
- Thread Component: Stainless steel (M34×1.5 specification, ensuring connection strength and wear resistance);
- Internal Parts: High-strength fiber-reinforced plastic (impact-resistant, self-lubricating, maintaining internal structural stability);
- Seals: PU (polyurethane) + NBR (nitrile butadiene rubber) (fuel-aging resistant, instantaneous sealing during separation).
- Specification Parameters:
- Thread: Fixed end M34×1.5 external thread, adaptive end optional internal/external thread;
- Breakaway Force: 1200-1500N (customizable, balancing safety redundancy and triggering reliability);
- Working Pressure: ≤0.6 MPa, Applicable Medium: Gasoline, Diesel, Working Temperature: -20℃~+60℃.
2. Working Principle, Scenarios & Usage
- Working Principle:
When the external force (such as violent dragging of the nozzle by a vehicle) reaches the preset value of 1200-1500N, the aluminum alloy housing and the M34×1.5 stainless steel thread component separate quickly, and the internal PU/NBR seals block the fuel channel simultaneously, achieving “breakaway = sealing, no leakage”.
- Application Scenarios:
M34×1.5 specification dispenser-nozzle high-pressure connection pipelines in gas stations, designed to prevent pipeline breakage and large-scale fuel leakage caused by violent dragging, protecting equipment and on-site safety.
-Usage:
1. Installation:
After confirming that the thread type (internal/external thread at the adaptive end) matches the pipeline, align the M34×1.5 external thread end with the gas station pipeline, and tighten the stainless steel thread component evenly with a wrench (verify sealing by a slight pressure test, no fuel seepage is qualified).
2. Operation:
The passage is smooth during normal refueling, and it automatically separates and seals when the external force meets the standard, without manual intervention throughout the process.
3. Maintenance:
Inspect the wear of M34×1.5 threads and the aging of PU/NBR seals quarterly; apply external force within the range of 1200-1500N with professional tools to verify separation and sealing performance, and replace parts in time if abnormal.
