Q47F/Y/H型固定式球阀 Fixed ball valve
结构特点及用途 Structural characteristics and uses
1、操作省力：球体由上下轴承支撑，减少摩擦，消除了由于进口压力推动球体与密封座形成的巨大密封负荷而造成过大的扭矩。
Operation:ball bearings supported by the up and down,to reduce friction,eliminate the pressure as imports to promote the formation of the sphere and the great seal sealed seat load caused by excessive torque.
2、密封性能可靠(见图1)：PTFE弹性材料密封圈嵌于不锈钢阀座内，金属阀座尾端没有弹簧，保证密封圈足够的预紧力，阀门在使用过程中密封面摩擦损时，在弹簧作用下阀门继续保证良好密封性能。
Sealing performance and reliable(see Figure 1):PTFE elastic material embedded in stainless steel valve seat ring,the metal spring seat no end,to ensure adequate preload ring,valve sealing surface in the course of friction loss When the valve under the action of the spring to ensure good sealing performance.
3、防火结构(见图2)：为防止由于骤热或火灾的出现，使聚四氟乙烯密封圈烧毁，发生较大泄漏，而助长火势，在球体与阀座间设置防火 密封环，在密封圈烧毁时，在弹簧力作用下，将阀座密封环迅速推向球 体上，形成金属与金属密封，起到一定程度的密封效果。耐火试验符合API 6FA和API607标准要求。
Fire structure (see Figure 2):In order to prevent the sudden appearance of heat or fire to burn PTFE seals,large leak occurred, and contribute to the fire,the fire ball and set the seal ring between the valve seat,in the ring when burned,under the action of the spring force will quickly push the ball valve seat seal ring, the formation of metal to metal seal,play a certain degree of sealing effect.The fireproof experiment conforms to API 6FA and the API 607 standard requests.
4、自动泄压功能(见图3)：当阀门中腔停滞的介质压力异常升高超过弹簧的预紧力时，阀座后退脱离球体，达到自动泄压的效果，卸压后阀座自动复位。
Automatic pressure relief function(see Figure 3):When the valve is in a stagnant medium pressure in the cavity increased over the spring preload,the seat back from the ball,to the effect of automatic pressure relief,pressure relief valve seat after automatically reset.
5、排泄管路：阀体上下均设置排泄孔，可检查阀座是否发生泄漏，在工作中，阀门处于全开或全关时，卸掉中腔压力，可直接更换填料；可以排放中腔滞留物，减少介质对阀门的污染。
辅助密封设置系统(客户需要请在订购时说明)
Discharge tube:the upper and lower body were set to vent, to check whether the leak valve seat,at work,the valve is fully open or fully closed,the removal of the pressure in the cavity can directly replace the packing;to emissions cavity left in reducing pollution of medium on the valve.
Auxiliary sealing set the system(customer needs when ordering please specify)
6、见图4：本阀门设计有辅助的阀座紧急密封系统，一旦密封受损或出现紧急情况而不能密封时，通过辅助密封系统向密封面注射相应的密封剂即可修复密封面，达到紧急密封。当输送的介质不洁或含有少量颗粒时，为保护密封面，确保达到可靠的密封，还可给 这一装置注射相应的清洗剂或润滑剂对密封面进行清洗。
Figure 4:The auxiliary valve seat designed for emergency sealing system,once the seal damage or emergency situations cannot be sealed,through the auxiliary sealing system corresponding to the sealing surface sealant injection sealing surface can be repaired,to an emergency seal.When the transport medium or containing a small amount of contaminated particles,in order to protect the sealing surface and ensure that a reliable seal,the device can also be injected to the appropriate cleaning agents or lubricants on the sealing surface cleaning.
7、广泛适用于食品、医药、石油、化工、天然气、钢铁、环保、造纸等输送管路介质的切断或流通。还可给这一装置注射相应的清洗 剂或润滑剂对密封面进行清洗。
Widely used in food,medicine,petroleum,chemical,natural gas,steel,environmental protection,paper and other media to cut off pipeline transportation or circulation.The device can also be injected to the appropriate cleaning agents or lubricants on the sealing surface cleaning.
