Double gate valve pneumatic wear-resisting ceramics
Pneumatic wear-resisting ceramics double gate valve is suitable for the power plants producing dry ash system, storehouse pumps, also can be used in mining, paper making, chemical and other kinds of dry dust, water, etc have wear medium in the pipeline for opening and closing. Use the nominal pressure 1. 0 mpa, the air pressure of 0. 6 - 0. 8MPa。 This reference Armstrong valve valve technology, shut down any direction all seal. The valve bonnet adopts WCB steel castings and seamless steel tube welding. Filler used hard seal. This valve sealing performance is good, high resistance to wear, small startup load, ash and knot less ash phenomenon, long service life. Pneumatic fast loading Angle seat valve flange type pneumatic Angle seat valve pneumatic double gate valve product characteristics 1, wear-resisting ceramics for welding connection on both ends of the tube, opening and closing of the valve is controlled by gear. 2, mainly through the valve closed the cover on the bevel gear mechanism and is able to adjust for the type of single ram, universal, clamp ring etc, borrow body guide for lifting movement. 3, the valve seat sealing surface using cobalt-based hard alloy surfacing and become, wear resistant, good abrasion resistance. 4. , the valve stem surface corrosion resistance of the nitriding treatment, has good corrosion resistance and abrasion resistance. 5, pressure self-tightening sealing mechanism, borrow wedge clamping sealing ring to achieve sealing medium pressure, the higher the medium pressure sealing performance is better.
