Pneumatic pneumatic valve pneumatic discharge summary of pneumatic valve. The air discharging ash pneumatic valve is a kind of rotary type automatic control of pneumatic valves, cavitation, scouring resistance, abrasion resistance, long service life, etc. The product can be used for chemical, oil, gas, petrochemical and other industries, especially suitable for medium containing particles of bad environment, such as slag discharge system, grey water system and gas oil containing other particles, such as sand, salt, stone and other conditions. Pneumatic discharge pneumatic valve has good sealing performance, long service life, small flow resistance coefficient and flow capacity is big, simple and reasonable structure, easy maintenance, maintain wait for a characteristic, and actuator based on the combination of the push type pneumatic actuators for the standard products, can also be combined with electric or electro-hydraulic acting actuators. Pneumatic discharge characteristics of pneumatic valve: 1) high resistance to wear, sealing surface spraying or pile of carbide, pneumatic body, seat surface hardness can reach HRC68 ~ 72 body and aerodynamic body cavity with wear-resistant liner, the seat port spray processing, high wear resistance. (2) the sealing performance is good: small amount of leakage and can reach the Class VI. (3) installed to unlimited, easy to install. (4) high safety: reduce accident parking, reduce maintenance costs, improve personnel and environmental safety. 5. Long service life: seat in a unique dustproof device, effectively prevent the media into the valve seat sealing surface to improve service life. 6. Stem adopts A182F ( 1Cr13） Overall forging and modulation treatment, hardness of HB220 ~ 250. Stem through flat key or spline connected to the handle, strong commonality, tear open outfit is convenient, stem has a blow-out proof design. All landowners pneumatic discharge of pneumatic valve filling knitting, flexible graphite sealing ring or tetrafluoroethylene sealing ring, lubricated stem in certain circumstances to achieve reliable seal. Today, according to need of pneumatic discharge pneumatic valve can be designed into the structure of anti-static, in the pneumatic body and valve body, valve stem and valve body between the conductive spring, avoid electrostatic spark to ignite flammable material, ensure the security of the system. Pet-name ruby seal in a variety of forms: can be chosen according to different working condition of soft seal and hard seal, fire seat structure; More than 6 pneumatic form, the following is a floating DN200 for fixed pneumatic form. Attending pneumatic discharge pneumatic valve seat in the auxiliary seal structure can be set up, in refill on the valve seat and valve stem area, emergency situations can be temporarily sealed, and can according to need to lengthen the valve stem with suitable buried laying venues. ⑪ sealing automatic compensation: metal seat end equipped with spring, when the sealing surface wear, pneumatic discharge under the action of a spring pneumatic valve has maintained a good seal. ⑫ work stability: aerodynamic body set up collar support, won't produce relative displacement after compression. ⑬ adopt fixed pneumatic ( Shaft type) Structure. In order to reduce the air discharging ash pneumatic valve operating torque and enhance the reliability of sealing and to avoid the aerodynamic body displacement after compression, so the pneumatic valve adopts pneumatic structure, this structure zui large extent ensure the valve opening and closing flexible, contrapuntal accurate, is not affected by the size of the medium pressure. ⑭ according to different working condition, pneumatic discharge of pneumatic valve pneumatic surface hardening treatment, can be better aerodynamic resistance to abrasion. Pneumatic valve pneumatic discharge main technical parameters: (1) the body forms: two postures or three postures: nominal diameter 1/2 'to 24' nominal pressure, ANSI 150 lb to 2500 lb connection mode: flange connection ( 射频、MFM环连接面) Material: A216 WCB, A216 WCC, A351 CF8, A351 CF8M, A351 CF3M and corresponding forgings or other alloy steel. Temperature: - 29 ℃ ~ + 280 ℃ bonnet: standard, material with body filler: PTFE, flexible graphite, nickel-based coating wire reinforced flexible graphite body: silver ( Epoxy resin) ； Stainless steel body without coating (2) components in the valve: the valve core type: type O valve core materials: A105, 420, A182 - F304 A182 - F316 or other alloy steel seat material: A105, 420, A182 - F304 A182 - F316 or other alloy steel flow characteristics: quick opening features rated stroke: 0 ~ 90 ° seat leakage rate: ANSI Class IV ~ VI pneumatic discharge principle of pneumatic valve structure: pneumatic discharge about the pneumatic valve is mainly composed of valve body, valve seat, valve core, valve stem, packing body, abrasion resistance, dust and other components package. Using fixed pneumatic, floating seat, the use of seat disc spring spring preload, make the seat close to the aerodynamic body, achieve zero clearance, prevent impurities from entering the seal, and achieve universal free activities and sealing requirements. Improved seal of the sealing effect and reduce the wear and extend the service life of the valve. Pneumatic discharge of the pneumatic pneumatic valve and valve seat sealing surface vice using new material, new technology, materials with nickel and chromium alloy spray welding welding sealing surface, thickness of 1 mm or more, thus improve the sealing surface hardness ( HRC68 ~ 72) To wear resistance, corrosion resistance, erosion resistance. Air discharge of pneumatic valve seat is equipped with dust-proof device, the valve core is rotated using dustproof set of sedimentary in pneumatic cleaning on the surface of the body surface impurities, prevent fouling, maintain aerodynamic body without adhesive and scratch phenomenon, reduce the leakage. Effectively prevent the medium into the hair with the pneumatic sealing surface, improve the service life of the valve. Type O sealing ring seat sealing area is equipped with dust-proof, disc spring dust type O sealing ring with the same Settings, effectively prevent the medium into the ring and disc spring chamber, make the seal ring and disc spring is permanent. Pneumatic discharge pneumatic valve body cavity are set wear-resisting, corrosion resistance, resistance to erosion, cavitation performance, such as effective to enhance the wear resistance of the valve. Pneumatic discharge the fly ash pneumatic valve stem of the structure design, shaft sleeve is equipped with sealing ring, effectively prevent the medium, to avoid the valve stem and shaft sleeve caused by medium card death phenomenon. : pneumatic heat preservation jacket ceramic pneumatic valve pneumatic sections of pneumatic valve pneumatic flange pneumatic valve pneumatic eccentric loading ceramic pneumatic valve pneumatic hard seal pneumatic valve
