超高压安全阀

超高压安全阀是一种专用于极端高压工况的安全保护装置，当系统压力超过预设安全值时，阀门迅速开启泄压，避免设备损坏或事故发生。其设计通常需满足100MPa以上的工作压力，适用于石油化工、超临界流体、高压试验装置、航空航天等关键领域。

超高压安全阀产品特点：

超高压耐受能力：采用高强度合金（如Inconel、钛合金）及特殊硬化工艺，确保阀体在极端压力下无变形或泄漏。

精准动作性能：多级先导控制或弹簧直接作用结构，确保阀门在设定压力±1%范围内准确启闭。

严苛密封要求：金属硬密封或自紧式密封设计，耐高温（可达800℃）及腐蚀性介质（如H₂S、酸性气体）。

安全冗余设计：部分型号配备机械锁定装置或双阀芯结构，防止误动作或二次超压风险。

超高压安全阀典型应用：

超临界水氧化（SCWO）系统的高压泄放

深海油气开采设备的井口安全控制

火箭燃料管路的高压保护

注：可补充具体参数（如压力范围100–1000MPa、通径尺寸、认证标准ASME/API 526等）。

Ultra-High Pressure Safety Valve Product Overview

An Ultra-High Pressure Safety Valve is a critical protection device designed for extreme pressure conditions (typically >100MPa). It rapidly opens to relieve excess pressure when systems exceed predefined limits, preventing equipment failure  catastrophic incidents. Commonly used in petrochemical, supercritical fluid, high-pressure testing rigs,  aerospace applications.

Key Features:

Extreme Pressure Resistance: High-strength alloys (e.g., Inconel, titanium)  specialized hardening processes ensure integrity under ultra-high pressures.

Precision Actuation: Multi-stage pilot control  spring-direct mechanisms guarantee actuation within ±1% of set pressure.

Robust Sealing: Metal hard-seal  self-energizing designs withstand high temperatures (up to 800°C)  corrosive media (e.g., H₂S, acidic gases).

Fail-Safe Redundancy: Optional mechanical locks  dual-disc structures mitigate false triggering  secondary overpressure risks.

Typical Applications:

Pressure relief in supercritical water oxidation (SCWO) systems

Wellhead safety control for deep-sea oil/gas extraction

High-pressure protection in rocket fuel pipelines
