Q11SA对夹式内螺纹球阀它具有旋转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。

       Q11SA对夹式内螺纹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，也可以做承插焊连接和对焊连接。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℃，耐压高可以到200MPa.可以安装气动 电动 液动等执行机构。Q11SA对夹式内螺纹球阀本身结构紧凑，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。

       Q11SA对夹式内螺纹球阀优点：

       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。

对夹式内螺纹球阀

对夹式内螺纹球阀是一种结合对夹式安装与内螺纹连接特点的阀门，通过阀体两端的内螺纹与管道连接，同时借助管道法兰或夹板夹持固定，兼具安装便捷与连接稳固的优势，适用于中小口径的低压至中压流体控制系统。

对夹式内螺纹球阀- 结构特点：阀体采用紧凑设计，两端设有内螺纹（如NPT、BSP等规格），可直接与带外螺纹的管道或接头连接；阀体中部设有法兰式凸缘，安装时通过螺栓将阀门夹在两个管道法兰之间，无需额外的阀门法兰，节省空间；核心部件包括球体、阀杆、阀座等，阀体材质多为黄铜、铸钢或不锈钢，阀座采用弹性密封材料（如聚四氟乙烯），确保密封稳定。

对夹式内螺纹球阀- 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对齐时，阀门开启，介质流通；旋转90°后，通孔与通道错开，阀门关闭，截断介质。因结构紧凑，流道通畅，流体阻力小，适合要求快速启闭的场景。

对夹式内螺纹球阀- 性能优势：安装方式灵活，对夹式设计减少了管道法兰间距，节省安装空间；内螺纹连接密封稳定，适合中小口径管道（通常DN15-DN50）；操作轻便，启闭迅速，可手动操作或搭配小型执行器实现自动化控制；维护方便，部分部件可单独拆卸更换，降低维护成本；适用介质广泛，包括水、油、气体等非腐蚀性或轻度腐蚀性流体。

对夹式内螺纹球阀- 适用范围：公称通径一般为DN15-DN50，工作压力多在PN16-PN40之间，适用温度范围-20℃至120℃（随材质变化）。广泛应用于民用建筑给排水、暖通空调、小型工业设备、灌溉系统等领域，用于控制介质的通断或流量调节。

Wafer-type internal thread ball valve is a valve combining the features of wafer-type installation internal thread connection. It connects to pipelines through internal threads at both ends of the valve body, while being fixed by clamping with pipeline flanges 夹板, offering the advantages of convenient installation stable connection. It is suitable for low to medium pressure fluid control systems with small to medium diameters.

Structural features: The valve body adopts a compact design, with internal threads (such as NPT, BSP specifications) at both ends, which can be directly connected to pipes joints with external threads. The middle part of the valve body is equipped with a flange-type flange; during installation, the valve is clamped between two pipeline flanges by bolts, eliminating the need for additional valve flanges saving space. Core components include the ball, valve stem, valve seat, etc. The valve body is mostly made of brass, cast steel, stainless steel, the valve seat uses elastic sealing materials (such as PTFE) to ensure reliable sealing.

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 aligns with the pipeline channel, the valve opens, the medium flows; after rotating 90°, the through-hole staggers the channel, the valve closes to cut off the medium. Due to its compact structure unobstructed flow channel, it has low fluid resistance, making it suitable for scenarios requiring quick opening closing.

Performance advantages: The installation method is flexible; the wafer-type design reduces the distance between pipeline flanges, saving installation space. The internal thread connection ensures reliable sealing, suitable for small to medium diameter pipelines (usually DN15-DN50). It is easy to operate with quick opening closing, can be manually operated equipped with small actuators for automatic control. Maintenance is convenient, as some components can be disassembled replaced individually, reducing maintenance costs. It is applicable to a wide range of media, including water, oil, gas, other non-corrosive slightly corrosive fluids.

Scope of application: The nominal diameter is generally DN15-DN50, the working pressure is mostly between PN16-PN40, the applicable temperature range is -20℃ to 120℃ (varying with materials). It is widely used in civil building water supply drainage, heating, ventilation air conditioning, small industrial equipment, irrigation systems other fields, for controlling the on-off flow regulation of media.
