Instruction of Pneumatic Ball Valve Series
Uses and Structural Features of Product
Pneumatic ball valve series are widely used in natural gas, oil chemical industry, metallurgy, papermaking, power, mining, printing and dying, biological pharmacy, daily chemicals, foodstuff and beverage, water treatment and air treatment etc. For the automatic or adjustment control of fluid, together with automatic pneumatic meters.
The Structureal Features of Pneumatic Ball Valves Series:
Pneumatic Actuator uses new-style AT pneumatic actuator, provided with both double-acting and single-acting types (spring reposition), driven by gear and rack with high dependability; big diamete valves are diven by AW pneumatic actuator on pull extraction manner, with reasonable stucture and large output torque as well as double-acting and single-acting types (spring reposition). Refer to our stylebook of pneumatic actuator for more details information.
•Shell Sturcture: As per useres' requirements and real working conditions, fixed ball valves can be designed to three structures including cast, forged and full-welded, and valves of full-welded structure are mainly applicable for buried use.
Unique ISealing Sturcture of Valve Base Floating ball valve adopts the sturcture of lip-type elastic sealing ring to insure the sealing dependability. For ball valves used in low-tension, ultra-low-tension or vacuum conditions, the valve-base sealing structure with leaf spring loading is adopted to maintain long-time reliable sesling. The valve-base of high-or medium-temperature ball valve may usepara-position polyphenylene of metal material.
According to the difference in pressure, medium character and sealing requirements, fixed ball valve may choose structures of front-ball sealing, back-ball sealing or front-back double sealing. The valve base of high-oor medium-temperature ball valve may use pare-position polyphenylene or metal material.
eObsturction and Drainage: When valve is io off-position, the valve bases at upper and lower stream will interdict the fluid, and the deposit in the cavty may be discharged by drainage device.
•Automatic Pressure-relieving Sturcture: In case of abnormal rise of pressure occurred in cloaca cavity, the mediums in it may drive the valve base with its self-thrust to realize automatic pressure relief. thus to ensure the safety of valve body.
• Reliable Sealing of Stem: Valve stem adopts the downward installation sturcture with back sesling. The sealing power increases along with the rise of medium pressure, thus to ensure reliable sealing of valve stem. In addition, stem will not burst forth in case of abnormal pressure rise.
•Fireproof Sturcture: Fireproof sturcture may be adopted for ball valve as per working conditions and users' requirements. The firep oof design confoms to API 60 and JB/T6899 standards etc. In case of soft sealing ring being damaged in fire, the Iieproof
structure can stop the large leakage of medium, thus to avoid further expansion of fire.
• Anti-static Strusture: When operating, the friction between sphere and base may cause static charge accumulated on the sphere. To avoid static spark, static device is provided on the valve to educt the electric charge on the sphere.
• Full Bore Structure and Reduced Bore Structure: These two serices are offered to meet users’ different requirements. The passage inside diameter of full bore ball valve is the same as that of pipe, making it convenient for control and cleaning. The weight of reduced bore ball valve is relativey smaller, but the fluid resistance is only arund 1/7 of that of stop valve with the same caliber. Therefore, the application prospect is much better for the latter.
