氢站用高压球阀产品概述

 氢站用高压球阀是专为氢气站（如加氢站、氢能储存与输送设施）设计的高压流体控制阀门，主要用于氢气的储存、压缩、加注等环节的通断控制，具备适应氢气特性及高压工况的特殊性能，是氢能基础设施中的关键设备。

 氢站用高压球阀结构设计：

 氢站用高压球阀 - 阀体多采用高强度不锈钢（如316L）或特殊合金材料，具备抗氢脆性能和耐腐蚀性，防止氢气渗透导致材料性能劣化。

氢站用高压球阀 - 密封结构采用金属密封或增强型聚合物密封（如改性PTFE），确保在高压下（通常35MPa以上，部分超高压型号达70MPa）的稳定密封，减少氢气泄漏风险。

氢站用高压球阀 - 阀杆采用防吹出设计，配合多重填料密封，提升操作安全性；球体经精密加工，表面光洁度高，减少流阻的同时具有密封面耐磨性。

 氢站用高压球阀工作原理：

通过旋转手柄或驱动装置带动阀杆，使球体旋转90°实现阀门的全开或全关。全开时，球体通孔与管道连通，氢气顺畅流通；关闭时，球体阻断流道，依靠球体与阀座的紧密贴合实现密封，精准控制氢气的输送与截止。

 Overview of High-Pressure Ball Valves for Hydrogen Stations

 High-pressure ball valves for hydrogen stations are specialized fluid control valves designed for hydrogen facilities (such as hydrogen refueling stations, hydrogen storage transportation systems). They are mainly used for on-off control in hydrogen storage, compression, refueling processes, with properties tailored to hydrogen characteristics high-pressure conditions, serving as key equipment in hydrogen energy infrastructure.

Structural Design：

Overview of High-Pressure Ball - The valve body is mostly made of high-strength stainless steel (e.g., 316L) special alloys, featuring excellent hydrogen embrittlement resistance corrosion resistance to prevent material degradation caused by hydrogen permeation.

Overview of High-Pressure Ball - The sealing structure adopts metal seals enhanced polymer seals (e.g., modified PTFE) to ensure reliable sealing under high pressure (usually above 35MPa, with some ultra-high-pressure models reaching 70MPa), reducing the risk of hydrogen leakage.

Overview of High-Pressure Ball - The valve stem uses an anti-blowout design with multiple packing seals to enhance operational safety; the ball is precision-machined with a high surface finish, reducing flow resistance while ensuring wear resistance of the sealing surface.

 Working Principle：

The valve is fully opened closed by rotating the handle actuator to drive the valve stem, rotating the ball 90°. When fully open, the ball's through-hole aligns with the pipeline, allowing smooth hydrogen flow; when closed, the ball blocks the flow path, achieving sealing through tight contact between the ball valve seat, precisely controlling hydrogen transportation shut-off.

 Product Features：

 Overview of High-Pressure Ball - Hydrogen Embrittlement Resistance High-Pressure Tolerance：Materials are specially treated to resist hydrogen-induced embrittlement of metals under high pressure, enabling long-term operation under 35MPa, 70MPa, etc.

Overview of High-Pressure Ball - Low Leakage Rate：The sealing structure meets hydrogen safety standards with extremely low leakage rates (typically ≤1×10⁻⁶ Pa·m³/s), ensuring safe operation of hydrogen stations.

Overview of High-Pressure Ball - Strong Compatibility：Smooth internal flow channels reduce turbulence pressure drop, compatible with dry, clean hydrogen to avoid impurity contamination chemical reactions.

Overview of High-Pressure Ball - Easy Safe Operation：Support manual automated control (e.g., pneumatic, electric) with quick switching (1/4-turn operation); some models are equipped with position feedback emergency shut-off functions.

 Application Fields：

Mainly used in key nodes of hydrogen refueling stations, such as outlets of hydrogen storage tanks, compressor inlets/outlets, refueling machine pipelines, connections for hydrogen long-tube trailers. They are also applicable to high-pressure hydrogen systems in hydrogen power generation fuel cell fields.
