Ventilation control pneumatic valve installation and instructions

ventilation butterfly pneumatic valve instructions:
ventilation butterfly pneumatic valve structure design should be combined with the working condition of use conditions of the pneumatic valve.
. Higher dust content in the temperature of smelting condition of big condition, the design of the ventilation control pneumatic valve can be used flat inclined plate structure, the structure of valve body between the butterfly plate and pneumatic gaps, the gap value based on pneumatic valve diameter and working condition are used to determine, general control in its channel area. % of less than, can meet ventilation butterfly pneumatic valve installation and the working condition of temperature change and melting process requirements.
. At higher temperature and dustiness smaller under the working conditions of acid, the design of the ventilation control pneumatic valve can be used vertical plate structure. The structure of sealing surface easy processing, the sealing surface gap value control area of the passage. % within. Pneumatic valve body and disc sealing deputy dimensional precision by mechanical processing to meet the design requirements.
. For high temperature, low pressure and seal requirements strict conditions, ventilation butterfly design adopts pneumatic valve lever type plane structure. The sealing pair of preparation and butterfly plate trajectory can meet high sealing performance of the network equipment technical requirements.
ventilation butterfly pneumatic valve body sealing choose different structure according to different conditions, conducive to the pneumatic valve working condition of the production and use. Ventilation control pneumatic valve shaft end structure design with good insulation and sealing effect of external support structure, which can realize the pneumatic valve two shaft end seal before they support, facilitate adjustment function, won't produce the shaft end jam. In direct connection or crank connecting rod mechanism and transmission mechanism, equipped with heat insulation sleeve can effectively away from high temperature environment on the influence of the transmission device, guarantee the normal work of the pneumatic valve. Large diameter ventilation butterfly pneumatic valve pneumatic valve body and disc should be based on conditions require the use of casting or welding form, stiffened plates shall be configured, select reasonable process scheme and materials, to enhance the rigidity of the product, to prevent deformation.
ventilation butterfly pneumatic valve installation notice:
ventilation butterfly pneumatic valve installation position in the pipe network and pipe network layout is have effect on the use of pneumatic valves, smoke of tube end the pneumatic valve is opened or pneumatic valve closed connection corner design funnel, regularly can prevent dust ash accumulation is overmuch, facilitate the rotation of the disc.
ventilation butterfly pneumatic valve installation also several problems should be paid attention to:
. Use metal gasket must ensure uniform load, to avoid the influence of temperature and weight or welding stress to bring additional pressure pneumatic valve, pneumatic valve flange and pipe deformation.
, pneumatic valves installed in place, a length of pipe shall be installed supporting bracket.
the flow direction of medium, pneumatic valve installation should be paid attention to, make the butterfly plate the opening direction of the flow direction of medium and pipeline, is advantageous to the medium flow rate since soot cleaning effect.
, strengthen the protective network overall thermal insulation layer, make the wall above the dew point temperature, low temperature sintering can be reduced dust dust. If the tube wall temperature is higher than the flue gas acid dew point, can avoid acid steam condensation on the heat pipe wall, the control of sulfur trioxide formation rate, the pneumatic valves use effect will be better.
ventilation butterfly pneumatic valve installation position as the pipeline design has a different location, such as horizontal, vertical and corner general standpipe install ventilation butterfly pneumatic valve use effect is good, not easy to dust, horizontal tube and to turn the worst effect. Pneumatic valve on both sides of the import and export corner is the easiest form drift and grey wall, pneumatic valve operating torque will increase somewhat.
