The purpose of the pneumatic ball valve, and structure characteristics

series pneumatic ball valve is widely used in natural gas, oil, chemical industry, metallurgy, papermaking, electric power, mining, printing, dyeing, biological pharmacy, daily chemical, food, beverage, water treatment and air treatment and other industries fluid control or adjust the control, pneumatic instrument and automation systems. Series 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; Pneumatic valve adopts series of large diameter 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 pneumatic ball valve of pneumatic valve body according to different user needs and actual working condition of the premise of design for the structure of forging, casting structure and all welded structure of three kinds of forms, including all welded structure of the pneumatic ball valve is mainly used for underground use.
special pneumatic valve seat seal structure:
floating ball type pneumatic valve adopts lip elastic sealing ring structure design, guarantee the reliability of the seal, for low pressure, low pressure or vacuum; Besides, pneumatic valve, ball with pneumatic valve seat seal structure of plate spring loaded, can ensure the long-term reliable seal pneumatic ball valve. Pneumatic valve, high temperature ball in pneumatic valve seat materials can choose para polystyrene or metal materials.
fixed pneumatic 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. Pneumatic valve, high temperature ball in pneumatic valve seat materials can choose para polystyrene or metal materials.
obstruction and excretion: when pneumatic valve in the closed state, upstream and downstream side of the pneumatic valve seat make liquid blocking, pneumatic valve body lumen of stagnant objects can be discharge by discharging device. Pieces
automatic pressure relief structure: the rise of cavity pressure on the abnormal phenomenon, the midplane medium can rely on itself thrust to promote pneumatic seat and automatic relief, so as to ensure the security of the pneumatic valve lift.
reliable pneumatic valve stem seal: pneumatic sealing backwards bottoms structure is used to stem, pour sealing force with medium pressure increases with increasing of the seal, so it can ensure the reliable pneumatic valve stem seal, and, when abnormal pneumatic valve stem booster, pneumatic valve rod will not spit out.
fire prevention structure: according to the working condition and the needs of users, pneumatic ball valve can be designed for fire prevention structure. Pneumatic ball valve of the refractory design execution API and JB/T scale, once a fire and make the soft seal when burning, pneumatic ball valve can prevent leakage of medium of fire prevention structure, prevent fire further expanded.
anti-static structure: when manipulating pneumatic valve, because the friction between the ball and pneumatic seat, can produce electrostatic charge and be latent in the sphere, to prevent electrostatic spark producing, especially on electrostatic device, pneumatic valve will be latent in the sphere of charge is derived.
full size structure and reducing structure: to satisfied the different needs of users, the company's products have a full size pneumatic ball valve and reducing the two series. Full size channel diameter of ball pneumatic valve and pipe diameter, facilitate cleaning, and reducing the weight of the series pneumatic ball valve is relatively light, but the flow resistance is just the same caliber as pneumatic valve/left and right sides, thus reducing series pneumatic ball valve application more broad vision.
