Pneumatic valve pneumatic lock slag _ pneumatic components factory valve industry

Pneumatic valve pneumatic pneumatic valve pneumatic lock slag overview: pneumatic lock slag pneumatic valve is mainly used for coal gasification coal water slurry into liquid slag discharge, and diverse slurry bed pressure systems, vaporization and dry pulverized coal and air flow in stove discharge process control, its medium is grey water with ash, chemical corrosion and strong mechanical erosion. Pneumatic valve pneumatic lock slag process parameters: pressure rating: Class300 ~ Class1500 temperature: - 46 ℃ ~ + 585 ℃ nominal size: NPS2 ~ NPS24 pneumatic lock slag pneumatic valve executive standard: 1, the valve design and manufacture according to API 6 d, BS5351 rules. 2, the structure of the valve according to ASME B16 length. 10 rules. 3, the size of the flange connection in accordance with the ASME B16. 5. 4, the pressure of the shell material - According to ASME B16 temperature. 34. 5, test and inspection by API598 regulation. Accord with NACE MR0175-6, the body parts 2002 rules. Pneumatic lock slag pneumatic valve features: (1) a stem blow-out proof design structure, gland under load, embedded inside gland, ensure the safety of the stem under any pressure, here also have on sealing function, further to ensure reliable sealing packing. (2) the valve stem not bear radial force, the valve closing force of medium by the upper and lower bearing, ensure the valve stem BuKa die under extreme conditions, and the upper and lower shaft and pneumatic body interface cemented carbide surfacing, can satisfy the demands of long-term and frequent switching valve life. (3) pneumatic body is made of stainless steel forging, the surface spray welding of nickel base alloy, the effective thickness of 0. 7 mm, hardness of HRC60 ~ 62, the aerodynamic body base material and surface material and the melting laminating, high bonding strength, to ensure that the spray welding material in use process will not be off, in the pneumatic channel and lip carbide surfacing, fully meet the requirements of wear resistance. (4) the seat sealing surface surfacing welding of nickel base alloy, the effective thickness of 2 mm, hardness of HRC58 - Channel within 60, seat carbide surfacing, fully meet the requirements of wear-resisting. (5) seat use spring loaded, spring material for Inconel750, adopt protective measures, on both sides of the spring to prevent debris into the spring chamber, effectively prevent spring failure. 6. On both sides of the seat sealing surface using scraper structure design, has since the opening and closing process cleaning function. All landowners body channels and ss liner, liner wall using supersonic spraying hard alloy, hardness of HRC70, satisfies the body resistance to erosion and corrosion resistance requirements. Today the body the connection parts adopt double seal design, ensure long-term reliable seal. Pet-name ruby pneumatic valve has the function of automatic relief, when the valve is closed, the pressure is higher than the closed pressure cavity, can automatic pressure relief to the low pressure side. Pneumatic lock slag pneumatic valve selection methods: customers when choosing pneumatic slag pneumatic valve lock, need to confirm that (1) product model (2) nominal size (3) nominal pressure (4) body material (5) trim material 6 connection mode need 7) using temperature actuator type switch or external regulation pet-name ruby whether need attachment whether attending the match solenoid valve explosion. : pneumatic high platform pneumatic valve pneumatic y-shaped three-way solenoid _ electric y-shaped three-way solenoid pneumatic cutting characteristics of pneumatic valve zero friction flexible pneumatic pneumatic valve
