Because medium grey powder particles, seating tend to have different degree of damage, scratch and abrasion, therefore, requires its ash discharging plate gate 'of the' main parts, such as disc, seat and zero devices shall have stronger resistance to wear. Non-metallic materials - — Para polystyrene, suit to use temperature is 300 ℃ or less, and PTFE harder than hard, to the satisfaction of the operation condition of the iron mill dedusting system, do not break is for the ideal tightly closed surface material. The valve structure such as think right and use, with flow guide hole and 'face' more rigorous closed tightly closed presupposition, not only can increase the wear resistance; Satisfied with its strict sealing performance; And can prevent the ash powder into the bottom of the valve body cavity. Reason deem appropriate and use the non-metallic materials ( Proposed that appropriate and use the counterpoint polystyrene) As tightly closed surface, can be satisfied with the working condition of temperature, wear resistance, and can be satisfied with its strict sealing performance. The ash handling system of medium - — 'Ash powder', not only the style is particles ( Occasionally, is spreading style is mixed style) And have a certain viscosity, electromagnetic directional valve has a oxygen carbon ( CO) 。 And sees fit and use of non-metallic materials, not only can save cost, reduce the processing difficulty, and can guarantee its strict sealing performance. The tightly closed than non-metallic materials, is due to the metal surface abrasion special circumstances, the initiation of a layer of oxygen compound, although this cover under oxygen compound corrosion on the part of the utility, can neglect the further corrosion of the metal, but if happen sliding, the layer of oxygen compound will be swept away a full, make out further corrosion of metal appearance, so to speed up the abrasion, weaken its tight sealing performance. In default, the electromagnetic directional valve products can make full use of existing flat gate valve with flow guide hole, change the seat to 'face' more rigorous closed tightly closed condition. 。 Because of the dust removal system of steel mills ironmaking condition of normal temperature to room temperature, electromagnetic directional valve sometimes at great temperature is 250 ℃. Q: editrice ash discharge a flat gate valve structure and utility: iron for steelmaking plant ash 'ash discharge plate gate' of the Marine valve system. The use of the working condition of dust removal system of ironmaking at zero pressure. Around 25 mpa range of low voltage; The temperature in the range of 250 ℃ or less ( Ordinary things condition for the normal temperature, sometimes flash temperature can reach 250 ℃) ; Nominal pipe diameter only from DN50mm ~ DN400mm ( The diameters of DN300mm) is the most common 。 For wear resistance, the metal to metal tightly closed the survival of the fixed number of year is the longest, but the metal to metal 'more tightly closed surface' hard tightly closed, allowing leakage on a standard, ( Such as the default is zero leakage costs will be very high and the processing difficulty is big) ; Second tightly closed than non-metallic materials. The seat material proposal sees fit and use 1 cr13.
