进口蒸汽气动球阀

进口蒸汽气动球阀是球阀配上气动执行器。气动执行器的执行速度相对较快，最快的开关速度0.05秒/次，所以通常也叫气动快速切断球阀。气动球阀通常配置各种附件，比如电磁阀、气源处理三联件、限位开关、定位器、控制箱等，以实现就地控制和远距离集中控制，在控制室里就可以控制阀门的开关，不需要跑到现场或者高空和危险地带来手动控制，在很大程度上节约了人力资源以及时间和安全性。蒸汽气动球阀只需要用气动执行器用气源旋转90度的操作和很小的转动力矩就能关闭严密。完全平等的阀体内腔为介质提供了阻力很小、直通的流道。通常认为球阀最适宜直接做开闭使用。球阀的主要特点是本身结构紧凑，易于操作和维修，蒸汽气动球阀开关轻便，体积小，可以做成很大口径，密封可靠，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，在各行业得到广泛的应用。

进口蒸汽气动球阀优点：

   1． 流体阻力小，其阻力系数与同长度的管段相等。 

　 2． 结构简单、体积小、重量轻。 

　 3． 紧密可靠，球阀的密封面材料广泛使用塑料、密封性好，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，气动球阀结构简单，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.  因为气动球阀动力源采用的是气体，一般为0.2-0.8MPa压力，相对比较安全。

Pneumatic valve inlet steam

Inlet steam pneumatic valve is coupled with a pneumatic valve actuators. Execution speed pneumatic actuator relatively fast, the fastest switching speed 0.05 seconds / times, so often called pneumatic quick disconnect valve. Pneumatic valve is usually equipped with various accessories, such as solenoid valves, air FRL, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control, in the control room can control the switching valve no need to go on-site or bring dangerously high altitude and manual control, in large savings in time and human resources and security. Just use steam pneumatic valve pneumatic actuator with air rotated 90 degrees operation and a small torque can be closed tightly. The body cavity of full equality for the media provided little resistance, through the flow channel. Generally considered the most suitable valve opening and closing done directly use. The main features of valve is its own compact, easy operation and maintenance, steam pneumatic valve switch light, small size, can be made into large-caliber, reliable sealing, simple structure, easy maintenance, and spherical sealing surface often in the closed state, can not easily be medium erosion in various sectors has been widely used.

Pneumatic valve inlet steam parameters:

????Gas seal test: 0.5 to 0.7

Working temperature: PTFE≤150 ℃ PPL≤300 ℃ Carbon ≤350 ℃

Suitable medium: water, oil, steam P: nitric acid (temperature ≤200 ℃) R: acetic acid class (temperature ≤200 ℃)

Structure Length: ANSI / ASME B16.10, API6D

Butt connection dimensions: ANSI / ASME B16.25

Inspection and Test: API598, API6D

Pneumatic valve inlet steam advantages:

???1. Fluid resistance, its drag coefficient with the same pipe lengths are equal.

2. Simple structure, small size and light weight.

3. Close and reliable valve sealing surface material widely used plastic, sealing, and has also been widely used in the vacuum system.

4. Easy to operate, opening and closing rapidly, from fully open to fully closed as long as the rotation of 90 °, to facilitate remote control.

5. Easy maintenance, simple pneumatic valve structure, seals are generally activities, the removal replacement is more convenient.

6. When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface.

7. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied.

8. Because pneumatic valve power source used is a gas, typically 0.2-0.8MPa pressure, relatively safe.
