Q41N美标法兰高压球阀它具有旋转90度的动作，旋塞体为球体，有圆形通孔或通道通过其轴线。球阀在管路中主要用来做切断、分配和改变介质的流动方向，它只需要用旋转90度的操作和很小的转动力矩就能关闭严密。球阀适宜做开关、切断阀使用，但近来的发展已将球阀设计成使它具有节流和控制流量之用，如V型球阀。

       Q41N美标法兰高压球阀的主体和附件都是锻造后再精加工，采用美标标准生产。可以做硬密封也可以做软密封。硬密封耐压42MPa,耐温630℃，软密封可以根据用户需要做成耐温80℃ 150℃和250℃，耐压高可以到200MPa.可以安装气动 电动 液动等执行机构。Q41N美标法兰高压球阀本身结构紧凑，密封稳定，结构简单，维修方便，密封面与球面常在闭合状态，不易被介质冲蚀，易于操作和维修，适用于水、溶剂、酸和天然气等一般工作介质，而且还适用于工作条件恶劣的介质，如氧气、过氧化氢、甲烷和乙烯等，在各行业得到广泛的应用。球阀阀体可以是整体的，也可以是组合式的。

       Q41N美标法兰高压球阀优点：

       1．流体阻力小，全通径的球阀基本没有流阻。

       2．结构简单、体积小、重量轻。

       3．紧密度好。它有两个密封面，而且目前球阀的密封面材料广泛使用各种塑料，密封性好，能实现完全密封。在真空系统中也已广泛使用。

       4．操作方便，开闭迅速，从全开到全关只要旋转90°，便于远距离的控制。

       5．维修方便，球阀结构简单，密封圈一般都是活动的，拆卸更换都比较方便。

       6．在全开或全闭时，球体和阀座的密封面与介质隔离，介质通过时，不会引起阀门密封面的侵蚀。

       7．适用范围广，通径从小到几毫米，大到几米，从高真空至高压力都可应用。

       8．由于球阀在启闭过程中有擦拭性，所以可用于带悬浮固体颗粒的介质中。

美标法兰高压球阀

 美标法兰高压球阀是符合美国标准（如ANSI/ASME B16.34、API 6D等）的高压流体控制阀门，采用法兰连接方式，适用于石油、天然气、化工等行业的高压管道系统，具有标准化程度高、耐压性能强的特点。

美标法兰高压球阀- 结构特点：阀体、球体等核心部件多采用锻造碳钢、不锈钢（如316L）或合金材料，经精密加工确保高强度和耐高压性能；法兰接口严格遵循美标尺寸标准（如Class 150、300、600、900、1500、2500等压力等级），密封面形式包括RF（突面）、RTJ（环连接面）等，适配美标管道系统；阀座采用金属密封或高性能复合密封材料，在高压工况下实现稳定密封，防止介质泄漏；部分型号配备防静电装置、防火结构及泄压孔，提升系统安全性。

美标法兰高压球阀- 工作原理：通过旋转阀杆带动球体旋转90°实现启闭。当球体通孔与管道通道中心线重合时，阀门全开，介质流通；旋转90°后，通孔与通道完全错开，阀门关闭，截断介质流动。操作轻便，可配合手动、气动或电动执行器，满足远程控制和自动化需求。

美标法兰高压球阀- 性能优势：符合美标规范，互换性强，便于项目配套；高压耐受能力突出，Class 2500等级可承受超高压（约42MPa以上）工况；密封性能好，在高压差下仍能保持零泄漏；流体阻力小，全通径设计减少介质输送压力损失；结构紧凑，维护方便，密封件和易损部件可单独更换，延长使用寿命。

美标法兰高压球阀- 适用范围：适用于天然气、原油、成品油、蒸汽、腐蚀性介质等高压流体，工作温度范围通常为-29℃至427℃（随材质变化），公称通径一般为DN15至DN600。广泛应用于北美及市场的高压管道工程、 offshore平台、炼化装置等，作为关键截断或控制设备使用。

American Standard flanged high-pressure ball valve is a high-pressure fluid control valve conforming to American standards (such as ANSI/ASME B16.34, API 6D, etc.). It adopts flanged connection is suitable for high-pressure pipeline systems in petroleum, natural gas, chemical other industries, featuring high standardization strong pressure resistance.

American Standard flanged high-pressure ball valve- Structural features: Core components such as valve body ball are mostly made of forged carbon steel, stainless steel (e.g., 316L) alloy materials, with precision machining to ensure high strength high-pressure resistance. The flange interface strictly follows American standard size specifications (such as pressure classes of Class 150, 300, 600, 900, 1500, 2500, etc.), with sealing face types including RF (Raised Face), RTJ (Ring Type Joint), etc., adapting to American standard pipeline systems. The valve seat uses metal seals high-performance composite sealing materials to achieve reliable sealing under high-pressure conditions prevent medium leakage. Some models are equipped with anti-static devices, fire-resistant structures pressure relief holes to improve system safety.

American Standard flanged high-pressure ball valve- Working principle: The valve is opened closed by rotating the valve stem to drive the ball to rotate 90°. When the through-hole of the ball coincides with the center line of the pipeline channel, the valve is fully open, allowing efficient flow of the medium; after rotating 90°, the through-hole is completely staggered the channel, the valve closes to cut off the medium flow. It is easy to operate can be equipped with manual, pneumatic electric actuators to meet the needs of remote control automation.

American Standard flanged high-pressure ball valve- Performance advantages: Compliant with American standards, it has strong interchangeability, facilitating matching in international projects; it has outstanding high-pressure resistance, with Class 2500 grade capable of withstanding ultra-high pressure (above approximately 42MPa) conditions; it has excellent sealing performance, maintaining zero leakage even under high pressure differences; it has low fluid resistance, the full-bore design reduces pressure loss in medium transportation; it has a compact structure convenient maintenance, with seals vulnerable parts replaceable individually to extend service life.

American Standard flanged high-pressure ball valve- Scope of application: Suitable for high-pressure fluids such as natural gas, crude oil, refined oil, steam, corrosive media. The working temperature range is usually -29℃ to 427℃ (varying with materials), the nominal diameter is generally DN15 to DN600. It is widely used in high-pressure pipeline projects, offshore platforms, refining chemical plants in North America international markets as a key shut-off control device.
