进口气动球阀的作用及优点
进口气动球阀的简介:
美国欧可气动球阀是由旋塞阀演变而来,它具有相同的旋转90度动作,不同的是旋塞体是球体,有圆形通孔或通道通过其轴线。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,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。球阀的主要特点是本身结构紧凑,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。球阀阀体可以是整体的,也可以是组合式的。
进口气动球阀的作用:
美国欧可气动球阀的工作原理是靠旋转阀芯来使阀门畅通或闭塞。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,不气动球阀易被介质冲蚀,在各行业得到广泛的应用。气动球阀和旋塞阀是同属一个类型的阀门,只有它的关闭件是个球体,球体绕阀体中心线作旋转来达到开启、关闭的一种阀门。
进口气动球阀的优点:
美国欧可气动球阀在管路中主要用来做切断速度快、分配和改变介质的流动方向。气动球阀是近年来被广泛采用的一种新型阀门,它具有以下优点: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,目前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。气动球阀如果漏气的话,相对液动、电动来说,气体可以直接排出,对环境没有污染,同时具有较高的安全性。9.相对于手动和涡轮转动球阀来说,气动球阀可以大口径配置,(手动和涡轮转动球阀一般都在DN300口径以下,气动球阀目前可以达到DN1200口径。)气动球阀已广泛应用于石油、化工、发电、造纸、原子能、航空、火箭等各部门,以及人们日常生活中。
Introduction of imported pneumatic ball valve:
USA and Europe Pneumatic ball valve was evolved from plug valve, it has the same rotation of 90 degrees of movement, different cocks body is a sphere, a circular through-hole or channel through its axis. Pneumatic valve only need pneumatic actuators used in gas source rotated 90 degrees to operate and a small torque can be closed tightly. Complete equality of the body cavity of the media to provide a little resistance, through the flow channel. Usually considered the most suitable valve directly to do the opening and closing to use, but recent developments have ball valve is designed to give it throttle and control the flow. The main features of valve is its own compact, easy operation and maintenance, and for general working media such as water, solvent, acid and gas, but also for the poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve can be a whole, can also be combined.
The role of imported pneumatic ball valves:
USA and Europe working principle of pneumatic ball valve by rotating the spool to make smooth or occlusion. Pneumatic ball valve switch is lightweight, small size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical often in the closed state, pneumatic ball easily medium erosion, has been widely used in various industries. Pneumatic ball valves and plug valves is the same type of valve closure is a sphere, a sphere around the body centerline rotation to achieve open and closed a valve.
Imported pneumatic ball valve advantages:
USA and Europe pneumatic ball valve is mainly used to cut off speed, distribution, and changing the media flow direction in the pipeline. Pneumatic ball valve is a new type of valve in recent years has been widely used, it has the following advantages: 1. Fluid resistance is small, the drag coefficient with the length of the barrel equal. Simple structure, small size and light weight. Closely reliable valve sealing surface materials widely used plastic, good sealing in the vacuum system has been widely used. Easy to operate, opening and closing rapidly, from fully open to fully closed rotated 90 ° to facilitate remote control. Easy maintenance, simple structure, pneumatic ball valves, and seals are generally activities, removal of the replacement is more convenient. (6) in the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, through the media, does not cause erosion of the valve sealing surface. 7 for a wide range of diameter from small to several millimeters, a few meters from the high vacuum to high pressure can be applied. Pneumatic ball power source is a gas, usually 0.2-0.8MPa pressure, relatively safe. Pneumatic ball valve leak, the relative hydraulic, electric, gas can be directly discharged to the environment, no pollution, but also has high security. . Phase For manual and turbine rotating ball valve, pneumatic valve can large-diameter configuration (manual and turbine rotating ball valves are generally below the DN300 caliber, pneumatic valve can now achieve the the DN1200 caliber.) Pneumatic ball valves have been widely used in petroleum, chemical power generation, paper, atomic energy, aviation, rockets and other departments as well as people's daily lives.
