Double block and bleed design and style(DBB)
Double stem sealing.
The ball can keep pressure sealing of CZPT when it is closed or completely opened.
Shorter upper sleeve reducces bearing load and procedure torue
Limit device assures the precise opening and closing situation of the valve
The vall and stem are divided so as to lessen stem load.
The stem adopts anti-blow-out design and style.
The sealing surface is inserted into te steel seat by CZPT or plastic
The metalbacked self-lubricating PTFE bearing and PTFE thrust washers
Decrease the opening torque and extend the services lifestyle of the valve.
Stem leakage can be prevented through the crisis grease fitting.

The tooth surface area hardness, it is divided into soft tooth surface equipment transmission and tough tooth surface equipment transmission. When the tooth floor hardness of the two wheels (or 1 of them) is significantly less than or equivalent to 350HBW, it is referred to as comfortable tooth surface area transmission when the tooth area hardness of the two wheels is >350HBW, it is referred to as challenging tooth area transmission. Delicate-tooth area equipment transmission is frequently utilised for common reduced-velocity gear transmission that does not demand substantial precision, and challenging-toothed surface equipment transmission is typically utilized for gear transmission that calls for strong bearing potential and compact framework.
Racks are utilised to transform rotary movement into linear movement. The spur tooth of the rack cut into 1 face of the sq. or circular rod section and function with the pinion, which is a little cylindrical gear that meshes with the rack. Usually, racks and pinions are collectively referred to as “rack and pinion”.
