电动固定式球阀
  (1)automatic pressure relief function:when the valve in the cavity of the medium pressure abnormal increase over the spring preload,the seat back from the ball,to achieve the effect of automatic pressure relief,pressure relief valve seat after automatic reset.
 
  (2):drain line are set to discharge hole on the valve body,can check whether the valve seat leakage occurs,in the work,the valve is fully open or fully closed,remove the pressure in the chamber,can directly replace the packing;can cavity left in emissions,reduce pollution medium on the valve.The auxiliary seal set system(customer needs please specify when ordering)
 
  (3)the operation of labor:ball from top to bottom bearing support,reduce friction,eliminating the pressure to promote the import of the ball and the sealing seat of the formation of a huge sealing load caused by too much torque.
 
  (4)sealing material seal available:PTFE Kmeria embedded in stainless steel valve seat,metal seat end with the spring to ensure adequate seal preload,the valve sealing surface is abraded during use,in the spring under the action of the valve to ensure good sealing performance.
 
  (5)the design of the valve seat supporting emergency sealing system,if the seal is damaged or emergency ten green conditions and can not be sealed,the assistant seal system to the sealant can repair the sealing surface of the sealing surface of the corresponding injection,reached the emergency seal.When the transport medium unclean or contain a small amount of particles,in order to protect the sealing surface to ensure the sealing,available,the device can also be injected to the corresponding cleaning agent or lubricant on the sealing surface cleaning.
 
  (6)is widely used in food,medicine,petroleum,chemical,gas,steel,environmental protection,paper and other media to cut off pipeline transportation or circulation.The device can also be injected to the corresponding cleaning agent or lubricant on the sealing surface cleaning.
 
  (7)structural fire protection:to prevent the sudden appearance of heat or fire,burning the PTFE sealing ring,large leak occurred,and contribute to the fire,in the ball and seat sealing ring is arranged between the fire,when burned in the ring,under the action of the spring force,the seat ring quickly push the ball,forming metal to metal seal,the sealing effect to a certain extent.
 
  (1)自动减压功能:当阀内腔中的介质压力异常增大超过弹簧预压,座椅靠背从球上,达到自动释压,自动复位后的减压阀座的效果。
 
  (2):排放管路设置在阀体上的排放孔,可以检查阀座是否发生泄漏,在工作中,阀门完全打开或完全关闭,清除室内压力,可直接更换包装;可使腔内排放,减少阀门上的污染介质。辅助密封设置系统(客户需要请在订购时说明)
 
  (3)操作劳动:球从上到下的轴承支撑,减少摩擦,消除压力促使进口球和密封座形成巨大的密封载荷,由过大的扭矩引起。
 
  (4)密封材料密封可选:PTFE Kmeria嵌入不锈钢阀座,金属阀座端带有弹簧以确保足够的密封预压,阀门密封面在使用过程中磨损,在弹簧的作用下,阀门保证良好密封性能。
 
  (5)阀座支撑紧急密封系统的设计,如果密封损坏或紧急十个绿色条件且不能密封,辅助密封系统对密封剂可以修复密封面的密封面相应注入,到达紧急密封。当运输介质不洁净或含有少量颗粒时,为了保护密封表面以确保密封,可用,设备也可以注入相应的清洁剂或润滑剂在密封表面清洁。
 
  (6)广泛应用于食品,医药,石油,化工,煤气,钢铁,环保,造纸等媒体,切断管道运输或流通。该装置还可以在密封表面清洗时注入相应的清洗剂或润滑剂。
 
  (7)结构防火:防止突然出现热或火,燃烧PTFE密封圈,发生大量泄漏,并有助于火灾,在球和座密封圈之间设置火灾,在燃烧时环,在弹簧力的作用下,座圈快速推动球,形成金属到金属密封,密封效果有一定的程度。
