Ball valves and plug valve is the same type of valves only its closure of a spheroid,spheroid around
a rotary axis lines to achieve valve body opened and closed a valve.
ball valve used to be cut off in the main line,distribution and change the direction of the flow medium.
ball valve is widely used in recent years a new type of valves.
Features:
1.ball valve fluid resistance small,and its resistance coefficient with the length of the barrael of equivalent.
2.the valve stem uses sealing below-installed structure. there is a sealing gasket between stem and body and make sealing force increasing with
medium pressure force increasing,ensure the stem reliable seal. and prevent stem to be rushed when the
pressure is abnormal rise in valve cage.
3.as customers' demand,ball valve can be design as anti-static structure and derive the charge on the sphere.
4.to ensure stem flexible rotation and reliability,set the self-lubrication bushings of smaller friction coefficient between stem and body and stem and packing gland,not
only reduce operating torque and make opening or closing more flexibility,but also avoid corrosion between
stem and body when valve not open for long time and then valve can be opened and closed.
5.using double cant elastic sealing ring structure, when sphere have pressure from different medium,the contact
area between sphere and sealing ring is also different. even sealing ring resist more force of medium,it will not be
damage and safe and reliablity.
6.6.according to working condition and customers' demand. ball valve can be design as fireproofing.
when line is fired and valve seat is burning out,fireproofing can stop medium to leak,then prevent fire
to expand. the structure of fire-resistant uses the standard for API607 and JBT6899.
7.using floating ball,on the pressure of medium,sphere can make certain shift and ensure sealing of
outlet end.
