Q41Y高温硬密封法兰球阀它具有旋转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。

      Q41Y高温硬密封法兰球阀的球体和阀座都是喷焊STL合金的，主体和附件也是锻造后再精加工，可以耐压42MPa,耐温630℃。可以安装气动 电动 液动等执行机构。Q41Y高温硬密封法兰球阀本身结构紧凑，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。

      Q41Y高温硬密封法兰球阀优点：

      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。

高平台球阀

高平台球阀是一种比较新型的球阀类别，采用新型的ISO5211平台结构，阀杆上方有平台，可直接安装执行器，无需支架，便于安装和拆卸 。

高平台球阀- 结构组成 ：主要由阀体、球体、阀杆、阀座和密封圈等组成。阀体是主体结构，支撑球体并控制流体通断；球体与阀座形成密封界面，通过旋转实现流体通断；阀杆连接球体，传递操作力；阀座与球体配合，密封性能。

高平台球阀- 工作原理：球体绕阀体中心线旋转来开启或关闭阀门。球旋转90度时，若在进、出口处呈现球面，则截断流体；若呈现通孔，则供介质通过。

高平台球阀- 产品特点：流体阻力小，阻力系数与同长度管段相等；结构简单、体积小、重量轻；密封性能好，密封面材料常为塑料，在真空系统中也可使用；操作方便，开闭迅速，只需旋转90°，便于远距离控制；维修方便，密封圈活动，拆卸更换容易；在全开或全闭时，密封面与介质隔离，不易被侵蚀；适用范围广，通径从小到几毫米，大到几米，从高真空至高压力均可应用。

高平台球阀- 应用领域 ：广泛应用于石油、化工、电力、冶金、制药等行业。如石油领域的输送管道和储罐系统，化工领域的流程控制系统，电力领域的热力管道系统等。

High - platform ball valve is a relatively new type of ball valve. It adopts the new - type ISO5211 platform structure. There is a platform above the valve stem, which allows the direct installation of the actuator without a bracket, facilitating installation disassembly. The product overview is as follows:

High - platform ball valve- Structural composition: It is mainly composed of valve body, ball, valve stem, valve seat sealing ring, etc. The valve body is the main structure, supporting the ball controlling the on - off of the fluid. The ball the valve seat form a sealing interface, the on High - platform ball valve- off of the fluid is realized through rotation. The valve stem connects the ball transmits the operating force. The valve seat cooperates with the ball to ensure the sealing performance.

High - platform ball valve- Working principle: The ball rotates around the central line of the valve body to open close the valve. When the ball rotates 90 degrees, if the spherical surface appears at the inlet outlet, the fluid is cut off; if the through - hole appears, the medium can pass through.

High - platform ball valve- Product features: It has a small fluid resistance, the resistance coefficient is equal to that of the pipe section of the same length. It has a simple structure, small volume light weight. It has good sealing performance. The sealing surface material is often plastic, it can also be used in vacuum systems. It is easy to operate, the opening closing are rapid, only requiring a 90 - degree rotation, which is convenient for remote control. It is easy to maintain, the sealing ring is movable, making disassembly replacement easy. When it is fully open fully closed, the sealing surface is isolated the medium, it is easy to be eroded. It has a wide range of applications, with a nominal diameter ranging a few millimeters to several meters, it can be applied high - vacuum to high - pressure.

High - platform ball valve- Application fields: It is widely used in petroleum, chemical, electric power, metallurgy, pharmaceutical other industries. Such as the transportation pipeline storage tank system in the petroleum field, the process control system in the chemical field, the thermal pipeline system in the electric power field.
