Detailed Introduction
Q47F/Y/H Fixed ball valve
Structural characteristics and uses
1、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、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、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、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 、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、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、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.
