Q641F/H/P _ pneumatic stainless steel pneumatic valve pneumatic components factory valve industry

Description of pneumatic pneumatic valve stainless steel pneumatic pneumatic valve: Q641F/H/P stainless steel pneumatic pneumatic valve is widely used in natural gas, oil, chemical industry, metallurgy, papermaking, electric power, mining, printing, dyeing, biological pharmacy, daily chemical, food and beverage, water treatment and air treatment and other industries fluid control or adjust the control, pneumatic instrument and automation systems. Stainless steel pneumatic pneumatic valve features: 1, pneumatic valve actuator: adopt new ats series pneumatic valve actuator, its structure obtained state utility model * * have a double-acting and single acting ( Spring return) , more safe and reliable performance; Large diameter stainless steel pneumatic pneumatic valve adopts the AW series pneumatic valve actuator, adopts the transmission fork type structure, reasonable structure, large output torque, double acting and single acting ( Spring return) 。 2, shell structure: pneumatic pneumatic valve body according to the requirements of the use of stainless steel and the actual conditions of different design for the structure of casting, forging structure and all welded structure of three forms, including all welded structure of the pneumatic valve is mainly suitable for underground use. 3, unique seat sealing structure: (1) floating pneumatic valve adopts the lip liner elastic sealing ring structure design, the structure of the national utility model * * more to make sure that the reliability and service life of the seal, for the working condition of low pressure, low pressure or vacuum with pneumatic valve, in which plate spring and seat sealing structure, to ensure the reliable seal for the pneumatic valve use for a long time. Medium and high temperature pneumatic valve seat materials can choose para polystyrene or metal materials. (2) fixed pneumatic valve according to the size of the pressure, choice of dielectric properties and the sealing requirements of pneumatic seal, pneumatic seal structure or double seal structure before and after. Medium and high temperature pneumatic valve seat materials can choose para polystyrene or metal materials. 4, blocking and discharge: when pneumatic valve closed, the dirty side of the seat to make liquid blocking, body lumen of stagnant objects can be discharge by discharging device. 5, the structure of the automatic pressure release: the abnormal rise of cavity pressure, lumen medium can rely on itself thrust to push the seat and automatic relief, so as to ensure the safety of the valve body. 6 reliable seal, valve stem: stem has inverted sealing structure in the bottoms of inverted sealing seal force increases with the increasing of medium pressure and, therefore, to ensure that the valve stem and reliable seal, and, when the pneumatic valve abnormal pressure, the valve stem will not spit out. 7, fire prevention structure: according to the working condition and the needs of users, pneumatic valve can be designed for fire prevention structure. Pneumatic valve refractory design implementation of the API 6 d and the requirements of the standard JB/T6899, once a fire and make the soft seal when burning, fire prevention structure of pneumatic valve to prevent leakage of medium large, prevent fire further expanded. 8, anti-static structure: when operating stainless steel pneumatic pneumatic valve, due to the friction between aerodynamic body and seat, and can produce electrostatic charge accumulation on the aerodynamic body, to prevent electrostatic spark producing, especially on antistatic guiding device, pneumatic valve will accumulate on the aerodynamic body charge is derived.
