CNG加气机枪头
· CNG加气机枪头基本定义:根据国家标准,CNG加气枪是“装于加气机上,与汽车用压缩天然气加气口连接,给车用气瓶充装天然气的手工操作专用装置”。它通常由加气嘴 (Nozzle)、三通阀 (Three-way valve) 和连接件组成。
· CNG加气机枪头核心功能:加气枪内部的三通阀是关键。加气结束后,它能排放加气嘴内残留的高压气体,确保拔枪操作在安全低压状态下进行。
· CNG加气机枪头安全设计与特性:为确保安全,加气枪设计有自动锁紧系统,能连接牢固;部分型号具备拉断保护功能,在意外拉扯时能自动断开,避免损坏设备;与天然气接触的非金属部件也需具备耐老化性和介质相容性。
· CNG加气机枪头主要技术参数:加气枪通常在高压下工作,例如常见最大工作压力为315 bar (约4568 PSI)或200-250 bar。流量性能是重要指标,不同型号的流量系数不同,以满足从轿车到巴士等不同车辆的加气速度需求。
· CNG加气机枪头兼容性与标准:加气枪必须与车辆加气口匹配。市场上许多产品遵循国际通用的 ANSI/CSA NGV1 和 ISO 14469 标准。在中国,还需符合 GB/T 19236—2003 国家标准。

CNG Dispenser Nozzle - Product Overview
A CNG Dispenser Nozzle is the output terminal of a CNG dispenser. Its core function is to safely rapidly connect to a vehicle's receptacle to complete the high-pressure refueling process.
· Definition: As defined by national standards, the CNG refueling nozzle is "a manually operated specialized device installed on the dispenser, which connects to the compressed natural gas refueling receptacle of a vehicle to fill the onboard CNG cylinder." It typically consists of a nozzle, a three-way valve, connectors.
· Core Function: The internal three-way valve is the key component. After refueling, it vents the residual high-pressure gas trapped within the nozzle, ensuring that disconnection can be performed safely under low pressure.
· Safety Design: To ensure operational safety, the nozzle incorporates an automatic locking mechanism to guarantee a secure connection. Many models are equipped with a breakaway function that automatically disconnects during accidental pull-away, preventing damage to the equipment. Non-metallic components in contact with the gas must also possess properties like aging resistance media compatibility.
· Technical Parameters: The nozzle operates under high pressure, with common maximum working pressures of 315 bar 200-250 bar. Flow performance is a critical metric, with different models offering varying flow coefficients to meet the refueling speed requirements of different vehicles, passenger cars to buses.
· Compatibility & Standards: The nozzle must be compatible with the vehicle's receptacle. Many products on the market adhere to internationally recognized standards such as ANSI/CSA NGV1 ISO 14469. In China, compliance with the GB/T 19236—2003 national standard is also required.
