Small diameter welded stainless steel by the pneumatic valve related advantages

small diameter welded stainless steel as the relevant advantages of pneumatic valve
new small diameter welded stainless steel by the pneumatic valve is the new development and production of alternatives to traditional coal-fired power plants with small diameter welding by the pneumatic valve is the upgrading of products. Product design has some characteristics as follows:
sealing deputy variable cone structure for advanced spherical sealing structure, sealing pair are in good agreement under any circumstances;
pneumatic valve, pneumatic valve sealing surface with high hardness hardness of hard gold plating materials with special process of molding and processing, pneumatic valve sealing surface hardness of HRC ( Ordinary pneumatic valve sealing surface hardness is in commonly HRC - power station Or so) After, even with frequent opening and closing seal surface is still intact, without any indentation, very often a change of the traditional product once pressure pneumatic valve sealing surface deep and irregular indentation conditions, thus greatly improving the sealing and service life of pneumatic valve, but also make the sealing surface cavitation resistance, resistance to erosion ability is greatly increased;
pneumatic valve closed pneumatic valve stem into high temperature medium will slightly due to heat expansion growth, pneumatic valve, pneumatic valve sealing surface between higher than pressure ( Even broken seal face) And use the open torque increase. New product reference to foreign products? （ Such as Japan okano high temperature and high pressure by the pneumatic valve) Design, will support two jin sex compensation effect to absorb the thermal expansion of the pneumatic valve rod;
the air valve stem nut structure inside the hole on the upper bracket for improved direct casting aluminum bronze gold ( Copper alloy in the middle of the hole pouring out) Then on the trapezoidal thread processing directly, not only improve the alignment ( Remove the coaxial degree cumulative error) , improving the operating flexibility, but also greatly reduces the consumption of copper alloy;
pneumatic valve adopts on manually. Mm steel plate stamping the handwheel ( The introduction of German technology) Pneumatic valve, reducing the weight; The handwheel strength and toughness than cast iron handwheel have greatly increased, thus raising the handwheel used in transportation, the accidental impact resistance; The handwheel heat dissipation area ( Surface area) Big, low operation temperature is not hot; Stainless steel by the pneumatic valve;
packing plate adopts the open type clamp, convenient operation; Open the upper end side with small convex platform, in order to make sure the upper bolt will not slip by accidental impact, to improve the safety and reliability;
increased the upper platen of packing and packing pressure set of spherical coordinate of cone Angle ( ° to °) Ends, making the eyelet bolt ball nut tighten out of sync, uneven, clamp cone really able to slide, automatic centering on supporting pressure spherical, so as to guarantee the pressing sleeve can always vertical, balanced pressure tight packing, and avoid the card by pressing sleeve skewed pneumatic valve rod surface.
for wheel and pneumatic valve stem handwheel party party may exist between the trace interval, in order to avoid the multiple operation hand wheel ( The handle) Under the belt after pine nut, nut increased the spring washer locking;
pneumatic valve connected to the bracket of adopts screw cold rolling, the flexible grinding, much more than a tool more drilling, milling, powder metallurgy powerful embedded rolling, body, cover and other parts, using advanced process of new product method to improve the machining efficiency, improve the processing quality, compared with the conventional products, to improve product performance and service life of at the same time, reduce manufacturing cost and product price products.
