Pneumatic ball valve
application:
pneumatic ball valve is a kind of control valves, pneumatic actuators is mainly used in natural gas, oil, chemical industry, metallurgy, papermaking, electric power, mining, printing, dyeing, bio-pharmaceutical and other air treatment industry to control the fluid flow control or mediation, pneumatic instrument and automation systems.
pneumatic ball valve structure features as follows:
pneumatic actuators: adopt new series GT type pneumatic actuators, a double-acting and single acting ( Spring return) , the pinion and rack drive, safe and reliable; Large diameter valve adopts series HAW, pneumatic actuators fork type transmission, reasonable structure, large output torque, double acting and single acting ( Spring return) ; Pneumatic actuator samples refer to our company.
shell structure: fixed ball valve body according to user needs and the actual working conditions of the different design for the structure of casting, forging structure and all welded structure of three forms, including all welded structure of ball valve is mainly suitable for underground use.
the unique seat sealing structure: floating ball valve USES the lip liner elastic sealing ring structure design, guarantee the reliability of the seal, for low pressure, low pressure or vacuum; Being used condition with ball valve, plate spring loaded valve seat sealing structure, to ensure the long-term and reliable sealing ball valves. Medium and high temperature ball valve seat materials can choose para polystyrene or metal materials.
fixed ball valve according to the size of the pressure, choice of dielectric properties and the sealing requirements of ball before sealing structure, seal structure after or before and after the double seal structure. Medium and high temperature ball valve seat materials can choose para polystyrene or metal materials.
block and drain: when the valve is closed, the upstream and downstream side of the seat to make liquid blocking, body lumen of stagnant objects can be discharge by discharging device.
automatic pressure relief structure: the abnormal rise of cavity pressure, lumen medium can rely on itself thrust to push the seat and automatic relief, to ensure the safety valve.
stem reliable seal: seal backwards bottoms structure is used to the valve stem, pour sealing force with medium pressure increases with increasing of the seal, so it can ensure that the valve stem and reliable seal, and, when abnormal booster valve stem, valve stem will not spit out.
fire prevention structure: according to the working condition and the needs of users, ball valve can be designed for fire prevention structure. Ball valve of the refractory design and execution of API607 standard JB/T6899 rules, once a fire and make the soft seal when burning, the fire prevention structure of ball valve can be prevent leakage of medium large, prevent fire further expanded.
anti-static structure: when operating the valve, because the friction between the ball and seat, can produce a cow and accumulation of electrostatic charge on the sphere, to prevent electrostatic spark producing, especially on electrostatic device, the valve will accumulate in the sphere of charge is derived.
