GJ61Y超高压截止阀
GJ61Y超高压截止阀是一种专为极端高压工况设计的工业阀门,采用锻造阀体和金属硬密封结构,适用于石油、化工、军事等领域中压力超过100MPa的苛刻环境。该阀门通过强制密封设计实现双向切断功能,具有耐高压、耐腐蚀、零泄漏等特点,符合API、ASME等标准,是超高压管道系统的关键安全部件。
GJ61Y超高压截止阀核心特点:
超高压性能:设计压力达150MPa,阀体采用整体锻造工艺(材质可选A105、F316、F51等),确保结构强度。
GJ61Y超高压截止阀金属硬密封:阀瓣与阀座采用司太立(Stellite)合金堆焊或碳化钨涂层,耐冲蚀、耐高温(≤650℃)。
双向密封:强制密封结构(GJ61Y型),正向与反向压力下均能实现零泄漏(泄漏等级达ANSIVI级)。
紧凑设计:加长阀盖结构(BB型),适应-196℃~550℃的极端温度范围,防止填料函超压。
多样化连接:支持法兰(RF/RTJ)、螺纹(NPT/BSPP)或焊接端(BW/SW)连接方式。
GJ61Y超高压截止阀典型应用:
石油天然气超高压井口装置
化工反应釜超临界流体管道
军事及航天高压试验系统
水刀切割设备(超高压水射流)
注:可根据实际参数补充压力-温度额定值(如ASME B16.34)、驱动方式(手动/齿轮/电动)等细节。
GJ61Y Ultra-High Pressure Globe Valve Product Overview
The GJ61Y Ultra-High Pressure Globe Valve is an industrial valve designed for extreme high-pressure conditions (>100MPa) in oil & gas, chemical, military applications. Featuring a forged body metal hard-seal structure, it provides bidirectional shutoff with zero leakage, complying with API ASME standards.
Key Features:
Ultra-High Pressure: Rated up to 150MPa; forged body (A105/F316/F51) ensures structural integrity.
Metal Hard-Seal: Stellite-overlaid tungsten carbide-coated disc/seat, resistant to erosion high temps (≤650°C).
Bidirectional Sealing: Force-sealed design (GJ61Y type) achieves ANSI VI leakage class under forward/reverse pressure.
Compact Construction: Extended bonnet (BB type) suits extreme temperatures (-196°C~550°C), preventing packing failure.
Versatile Connections: Flange (RF/RTJ), threaded (NPT/BSPP), welded ends (BW/SW) available.
Typical Applications:
Oil & gas wellhead ultra-high pressure systems
Supercritical fluid pipelines in chemical reactors
Military/aerospace high-pressure test rigs
Waterjet cutting equipment (ultra-high pressure water)
