- pneumatic butterfly valve New type of pneumatic on-off butterfly valve forms and characteristics

in recent years, with the rapid development of equipment manufacturing industry in our country, especially the requirement of increasing the heat treatment aspect, in metallurgy, machinery and other industries, in order to improve the gas car type heat treatment furnace temperature uniformity, more use of impulsive control method of controlling the combustion. In order to control the fire and small fire in the state of the burner, the need to set up in front of the burner air lines a pneumatic valve, the characteristics of the pneumatic valve is: the switch position is adjustable, adjustable speed quickly, work stable and reliable, high temperature resistant ℃. According to the above requirements developed a new type of pneumatic on-off butterfly valve. Existing problems of pneumatic valve on-off butterfly pneumatic valve two positions that open and close is adjustable, and action is frequent, requires the use of life in more than ten thousand times. At present this pneumatic valve mainly has three type of pneumatic butterfly valve and the electric pneumatic valve on-off butterfly two kinds. Three type of pneumatic butterfly valve is given priority to with domestic, its cylinder mechanism is complex, through both on and off of the air supply pipe pneumatic valve three position, because in order to realize the three position, so the cylinder is installed in the spring. Field use found that the pneumatic valve failure rate is high, the first is the cylinder itself quality problem, also because of the spring in the case of higher temperature work not ideal, also make the two position adjustment is limited in the reliability of the pneumatic valve. Electric pneumatic valve on-off butterfly for two positions, the use of electric drive control pneumatic valve action, price is relatively expensive, mainly imported. Due to its smaller torque and electric actuators is not suitable for rapid positive &negative action, in order to adjust the speed also need to add a damper to adjust action speed, pneumatic valve structure is relatively complex. New forms and features of development of pneumatic valve on-off butterfly design new pneumatic valve requirements: action quickly adjustable, pneumatic valve switch position is adjustable, long service life and high temperature resistant characteristics. Combined with the requirements of the pneumatic valve development focus on the pneumatic valve drive the execution parts and movement of material selection. Pneumatic on-off butterfly valve adopts special pneumatic device, complete the automatic pneumatic valve switch, speed regulation and the adjustment of the size of fire location. Pneumatic components with high temperature resistant materials at the same time, it can realize the pneumatic valve ℃ high temperature resistant. This general specification pneumatic components is small, so the price is very cheap. The ball mill cast iron as the scaffold and the connection, because the material itself has the lubrication, no additional add lubricant can ensure the service life. Pneumatic actuators with bidirectional output shaft, two-way external regulation, and used to solve two position adjustment pneumatic valve size fire position adjustment problems. Using fluorine rubber sealing ring, cylinder itself can ℃ high temperature resistant. Using graphite as filler, high temperature resistance, good lubrication performance. And the use of pneumatic valve rod material for Cr, heat resistance and rust resistance can meet the requirements. Select the connection and support materials for ball mill cast iron, ensure the strength of the case, can also be lubrication. The pneumatic valve has the movement speed and adjustable speed, high temperature resistant, suitable for frequent movement, the service life is long, the advantages of low cost, suitable medium for high temperature air. Using 3 d graphics design of pneumatic valve, pneumatic valve becomes more beautiful. New on-off pneumatic valve application of new pneumatic butterfly valve used in a certain special steel base rough rolling mill in years, in the car type heat treatment furnace, the practical effect is good. New pneumatic valve pipeline according to the size of the fire in front of the furnace, gas decorate two pneumatic fast by the pneumatic valve, air decorate a pneumatic valve on-off butterfly now this pneumatic valve will work in recent years, the time, work is very stable, response quickly. On-site maintenance quantity few, compared with the original double a butterfly pneumatic valve and reduces the cost, with the outcome. Conclusion the new pneumatic relative original on-off butterfly valve pneumatic valve to reduce a control point, reduce the cost. And adopted high temperature resistant, no spring double external regulation of pneumatic draw stem cylinder itself quality is reliable, and cylinder ability ℃ high temperature. Although the air in the pneumatic valve temperature up to ℃ or so, but the location to the cylinder temperature is generally under ℃. Cylinder speed quickly, plus speed adjustment function, effectively avoid the air pneumatic valve too fast when they cause fire in size change on the impact of the burner. Equipped with the pneumatic valve make combustion system is both stable and fast reaction, can say the pneumatic valve sets the high temperature resistant, long life, low cost, action quickly to mediate multiple advantages in one. Along with our country more and more high to the requirement of flame heat treatment furnace, the new pneumatic valve will be widely used.
