電動熟料球閥
  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.
 
  電動塑料球閥由旋塞閥發展而成。它具有相同的運動升高90度,是旋塞體是不同的球體,有通過其軸線的圓孔或通道。球體和開口的比例應當使得當球旋轉90度時,入口和出口應當是全部現有球體,從而切斷流動。
 
  電動塑料球閥只需要90度的旋轉操作,小扭矩可以緊密關閉。體腔完全平等,為介質提供一點阻力,通過流道。一般認為最合適的閥門開閉采用直接做做,但最近的開發設計使其能夠具有球閥和節流控制的目的。閥本身的主要特點是緊湊,易于操作和維護水,溶劑,酸和天然氣一般工作介質,但也適用于介質的惡劣工作條件,如氧氣,過氧化氫,甲烷和乙烯。閥體可以是整體,也可以組合使用。
 
  電動塑料球閥的工作原理和實際效果
 
  球閥旋轉閥的工作原理*喜歡使閥門流動或堵塞。閥門開關燈,體積小,直徑大,密封性好,結構簡單,維修方便,密封面和球面常常處于封閉狀態,介質不易被腐蝕,廣泛應用于各行各業。
 
  電動塑料球閥和旋塞閥屬于同一類型的閥門,只有其關閉是一個球,球體繞中心體旋轉實現打開,關閉閥門。
 
  球閥在管道中主要用于切斷,分配和改變介質的流動方向。電動塑料球閥近年來得到廣泛應用,新型閥門,具有以下優點:
 
  1流體阻力小,并且電阻系數等于相同長度的阻力系數。
 
  2.結構簡單,體積小,重量輕。
 
  3緊密可用,目前閥門密封面材料廣泛應用塑料,密封性好,在真空系統中也得到廣泛應用。
 
  4.操作方便,快速開,關,從全開到全關,只要90度旋轉,便于遠程控制。
