电动熟料球阀
  Electric plastic ball valve is evolved by the plug valve.It has the same movement raised 90 degrees,is the cock body is different sphere,there are circular holes or channel through its axis.The sphere and the ratio of openings should be such that when the ball is rotated 90 degrees,in the inlet and outlet should be all the present sphere,thus cutting off the flow.
 
  Electric plastic ball valve only need 90 degrees rotation of the operation and a small torque can be closed tightly.The body cavity of full equality for the media to provide a little resistance,through the flow channel.Generally considered the most suitable valve opening and closing used directly to do,but the recent development has been designed to enable it to have the ball and throttle flow control purposes.The main features of the valve itself is compact,easy operation and maintenance for water,solvents,acids,and natural gas general working media,but also applies to poor working conditions of media,such as oxygen,hydrogen peroxide,methane and ethylene.The valve body can be whole,it can be combined.
 
  Working principle and practical effect of electric plastic ball valve
 
  The working principle of ball valve rotary valve*love to make the valve flow or occlusion.Valve switch light,small size,large diameter can be made available,sealing,simple structure,easy maintenance,sealing surface and spherical often in the closed state,the media can not easily be eroded,widely used in various industries.
 
  Electric plastic ball valves and plug valves are belong to the same type of valve,only its closure is a ball,the ball around the center of the body to make a rotation to achieve the open,close a valve.
 
  Ball valve in the pipeline is mainly used to cut off,distribution and change the flow direction of the media.Electric plastic ball valve is widely used in recent years,a new type of valve,it has the following advantages:
 
  1 fluid resistance is small,and the coefficient of resistance is equal to that of the same length.
 
  2 simple structure,small size and light weight.
 
  3 closely available,the current valve sealing surface material widely used plastic,good sealing,in the vacuum system has also been widely used.
 
  4 easy operation,open and close rapidly,from fully open to fully closed as long as 90 degree rotation,facilitate remote control.
 
  电动塑 料球阀由旋塞阀发展而成。它具有 相同的运动升高90度,是旋塞 体是不同的球体,有通过 其轴线的圆孔或通道。球体和 开口的比例应当使得当球旋转90度时,入口和 出口应当是全部现有球体,从而切断流动。
 
  电动塑料球阀只需要90度的旋转操作,小扭矩可以紧密关闭。体腔完全平等,为介质提供一点阻力,通过流道。一般认 为最合适的阀门开闭采用直接做做,但最近 的开发设计使其能够具有球阀和节流控制的目的。阀本身 的主要特点是紧凑,易于操作和维护水,溶剂,酸和天 然气一般工作介质,但也适 用于介质的恶劣工作条件,如氧气,过氧化氢,甲烷和乙烯。阀体可以是整体,也可以组合使用。
 
  电动塑 料球阀的工作原理和实际效果
 
  球阀旋 转阀的工作原理*喜欢使 阀门流动或堵塞。阀门开关灯,体积小,直径大,密封性好,结构简单,维修方便,密封面 和球面常常处于封闭状态,介质不易被腐蚀,广泛应用于各行各业。
 
  电动塑 料球阀和旋塞阀属于同一类型的阀门,只有其关闭是一个球,球体绕 中心体旋转实现打开,关闭阀门。
 
  球阀在 管道中主要用于切断,分配和 改变介质的流动方向。电动塑 料球阀近年来得到广泛应用,新型阀门,具有以下优点:
 
  1流体阻力小,并且电 阻系数等于相同长度的阻力系数。
 
  2.结构简单,体积小,重量轻。
 
  3紧密可用,目前阀 门密封面材料广泛应用塑料,密封性好,在真空 系统中也得到广泛应用。
 
  4.操作方便,快速开,关,从全开到全关,只要90度旋转,便于远程控制。
