91N卡套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。

Q91N卡套高压球阀的主体和附件都是锻造后再精加工，可以做单卡套连接和双卡套连接。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℃，耐压可以到200MPa.可以安装气动 电动 液动等执行机构。Q91N卡套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。

Q91N卡套高压球阀优点：

      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．紧密稳定。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。

卡套高压球阀产品概述

卡套高压球阀是一种采用卡套式连接的高压阀门，通过卡套与管道的机械咬合实现密封，无需焊接或螺纹密封，适用于高压流体系统中介质的通断控制，具有安装便捷、密封稳定、耐高压的特点。

卡套高压球阀- 连接方式：采用卡套连接结构，将卡套套入管道后与阀体压紧，通过卡套刃口嵌入管道外壁形成紧密密封，安装拆卸快速，可重复使用，适配中小口径管道（通常≤DN50），尤其适合需要频繁维护的高压场景。

卡套高压球阀- 结构特点：阀体多采用锻造高强度材料（如不锈钢、合金结构钢），抗高压性能好，工作压力可达3000PSI至10000PSI（或更高）；球体与阀座精密配合，确保高压下的启闭稳定性；阀杆采用防吹出设计，提升操作安全性。

卡套高压球阀- 密封性能：阀座选用耐高压、耐磨损的材料（如金属密封件、增强聚四氟乙烯等），配合卡套的双重密封（径向密封+端面密封），可有效防止高压介质泄漏，满足严苛工况的零泄漏要求。

卡套高压球阀- 操作方式：以手动操作为主，手柄旋转90°即可完成全开或全关，操作轻便，响应迅速；部分型号可配备气动、电动驱动装置，适应自动化控制系统需求。

卡套高压球阀- 适用范围：工作温度根据密封材料不同可达-20℃~300℃，适用于液压油、水、气体、腐蚀性介质等高压流体，广泛应用于液压系统、高压测试设备、石油开采、船舶重工、化工高压管路等领域。

 The compression fitting high-pressure ball valve is a type of high-pressure valve using compression fitting connection. It achieves sealing through mechanical engagement between the compression fitting the pipeline, without welding thread sealing. It is suitable for on-off control of media in high-pressure fluid systems, featuring convenient installation, reliable sealing, high-pressure resistance.

 The compression fitting high-pressure ball valve- Connection method: Adopts a compression fitting structure. The ferrule is sleeved into the pipeline then pressed against the valve body, forming a tight seal through the ferrule's cutting edge embedding into the outer wall of the pipeline. It allows quick installation disassembly, can be reused, is suitable for small medium-diameter pipelines (usually ≤DN50), especially for high-pressure scenarios requiring frequent maintenance.

 Structural features: The valve body is mostly made of high-strength forged materials (such as stainless steel, alloy structural steel) with excellent high-pressure resistance, with a working pressure up to 3000PSI to 10000PSI ( higher). The ball valve seat are precisely matched to ensure stable opening closing under high pressure; the valve stem adopts a blow-out proof design to enhance operational safety.

The compression fitting high-pressure ball valve- Sealing performance: The valve seat is made of high-pressure wear-resistant materials (such as metal seals, reinforced PSeE, etc.). Combined with the double sealing of the compression fitting (radial seal + end face seal), it can effectively prevent leakage of high-pressure media, meeting the zero-leakage requirements of harsh working conditions.

The compression fitting high-pressure ball valve- Operation mode: Mainly manually operated, with a 90° rotation of the handle to complete full opening closing, featuring easy operation quick response. Some models can be equipped with pneumatic electric drive devices to meet the needs of automated control systems.

The compression fitting high-pressure ball valve- Application range: The working temperature can reach -20℃~300℃ depending on the sealing material, suitable for high-pressure fluids such as hydraulic oil, water, gas, corrosive media. It is widely used in hydraulic systems, high-pressure testing equipment, oil exploitation, shipbuilding heavy industry, chemical high-pressure pipelines other fields.
