CNG天然气拉断阀

CNG25-1"-SAE拉断阀主要用途:

      CNG25-1"-SAE拉断阀设计安装在化工原料(如液态丙烷、氨水、环氧乙烷、液化石油气、丁二烯、工业甲醇、天燃气)的装卸软管上,当承受一定拉力时,拉断阀会自动断开,防止因装卸槽车的无意遛车而拉断装卸管引起泄漏,防止意外的发生而造成人员和设备的更大危害。此阀门需人工复位并可重复拉断使用。阀门有:法兰和内螺纹两种连接方式。内螺纹又为NPT3/8和1/2,常用在加气机(柜)上。适用于CNG槽车卸车软管系统上正常是NPT1或者G1,CNG25-1"-SAE拉断阀可重复拉断复位使用。

CNG天然气拉断阀

CNG天然气拉断阀(CNG Breakaway Coupling)是一种专为压缩天然气(CNG)加注系统设计的安全保护装置,用于在突发外力拉扯或过载情况下自动切断并密封管路,防止天然气泄漏,确保人员和设备安全。该阀门广泛应用于CNG加气站、车载燃料系统、天然气运输设备等领域。

CNG天然气拉断阀核心特点:

紧急拉断保护:

当软管受到异常拉力(如车辆意外移动)时,阀门瞬间断开并自动封闭两端,阻止气体泄漏。

CNG天然气拉断阀双重密封设计:

内置双向截止阀,拉断后两端同时密封,符合ISO 17268等安全标准。

CNG天然气拉断阀快速复位功能:

拉断后可手动或自动复位,无需更换部件,维护简便。

高压适应性:

工作压力可达250 bar(或更高),适用于CNG高压输送环境。

CNG天然气拉断阀耐腐蚀材质:

阀体采用不锈钢(316)或铝合金,密封件为耐油耐高温橡胶(NBR/HNBR),确保长期稳定性。

CNG天然气拉断阀典型应用:

CNG加气站(加气机与车辆连接管路)

天然气公交车/卡车燃料系统

移动式CNG运输设备

工业天然气供应管道

注:可根据具体参数(如拉断力阈值、认证标准EN 14432)或定制需求(如防爆等级)补充说明。

CNG Breakaway Coupling Product Overview

The CNG breakaway coupling is a safety device designed for Compressed Natural Gas (CNG) refueling systems, which automatically severs seals the pipeline under sudden external force (e.g., hose pull-away) to prevent gas leakage ensure personnel/equipment safety. It is widely used in CNG stations, vehicle fuel systems, gas transportation equipment.

Key Features:

Emergency Breakaway Protection:

Instantly disconnects seals both ends when excessive tension (e.g., vehicle movement) is detected.

Dual Sealing Mechanism:

Integrated dual shut-off valves post-breakaway, compliant with ISO 17268 safety standards.

Quick Reset Function:

Manual automatic reset after activation, no part replacement required.

High-Pressure Resistance:

Operating pressure up to 250 bar ( higher), suitable for CNG high-pressure applications.

Corrosion-Resistant Materials:

Stainless steel (316) aluminum alloy body with oil/heat-resistant rubber (NBR/HNBR) seals for durability.

Typical Applications:

CNG refueling stations (hose connections between dispensers vehicles)

NGV (Natural Gas Vehicle) fuel systems

Mobile CNG transportation units

Industrial gas supply pipelines
