電動固定式球閥
  (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)自動減壓功能:當閥內腔中的介質壓力異常增大超過彈簧預壓,座椅靠背從球上,達到自動釋壓,自動復位后的減壓閥座的效果。
 
  (2):排放管路設置在閥體上的排放孔,可以檢查閥座是否發生泄漏,在工作中,閥門完全打開或完全關閉,清除室內壓力,可直接更換包裝;可使腔內排放,減少閥門上的污染介質。輔助密封設置系統(客戶需要請在訂購時說明)
 
  (3)操作勞動:球從上到下的軸承支撐,減少摩擦,消除壓力促使進口球和密封座形成巨大的密封載荷,由過大的扭矩引起。
 
  (4)密封材料密封可選:PTFE Kmeria嵌入不銹鋼閥座,金屬閥座端帶有彈簧以確保足夠的密封預壓,閥門密封面在使用過程中磨損,在彈簧的作用下,閥門保證良好密封性能。
 
  (5)閥座支撐緊急密封系統的設計,如果密封損壞或緊急十個綠色條件且不能密封,輔助密封系統對密封劑可以修復密封面的密封面相應注入,到達緊急密封。當運輸介質不潔凈或含有少量顆粒時,為了保護密封表面以確保密封,可用,設備也可以注入相應的清潔劑或潤滑劑在密封表面清潔。
 
  (6)廣泛應用于食品,醫藥,石油,化工,煤氣,鋼鐵,環保,造紙等媒體,切斷管道運輸或流通。該裝置還可以在密封表面清洗時注入相應的清洗劑或潤滑劑。
 
  (7)結構防火:防止突然出現熱或火,燃燒PTFE密封圈,發生大量泄漏,并有助于火災,在球和座密封圈之間設置火災,在燃燒時環,在彈簧力的作用下,座圈快速推動球,形成金屬到金屬密封,密封效果有一定的程度。
