Product Design Features
Serial floating ball valve are mainly applied to natural gas, oil produces ,chemical engineering, metallurgy, city building, environment protection, pharmacy and food industries, among which the anti-sulphur series are used for long delivery pipes of natural gas that contains hydrogen sulphide medium, a lot of impurity and corrosive substance.
The design features of the floating ball valves include:
Double cant elastic seat ring or V-shaped groove seal ring structural design is adopted to ensure sealing reliability. As for low-pressure, ultralow pressure or vacuum-operated ball valve, a plate spring-loaded sealing structure of valve base is adopted to ensure their longterm sealing reliability. As for moderate or high temperature ball valve, Para-position polyphenylene or mental can be adopted for valve base material.
Automatic pressure relief structure
When the pressure in cloaca cavity increase singularly, the cavity medium can push valve base by its own thrusting force, which result in automatic pressure relief and valve security assurance.
Reliable Sealing of Valve Rod
The valve rod adopted downward installation structure with back sealing. The sealing force will increase together with the heightening of medium pressure, which can ensure the sealing reliability. Moreover, even if the pressure in valve cavity increases singularly, the valve rod will not burst out.
Fire-resistant Structure
According to the operating condition and users requirement, ball valve can be designed with a fire resistant structure up to the fire-resistant standards of API607 and JB/T6899. Once the soft seal ring is burnt out on fire, the structure can avoid serious leaking of the medium and prevent the
fire from scaling up.
Anti-static Structure
While operating the valve, the friction between the sphere and the base will produce static charges accumulating on the sphere. To avoid static ***rkle, the fire-resistant device is designed to derive the accumulated static ***r |
