Abstract

The invention discloses a compression air bag sealing double-layer ash discharging valve, belongs to valves and particularly relates to a double-layer ash discharging valve with an upper sleeve valve and a lower sleeve valve. The compression air bag sealing double-layer ash discharging valve comprises an upper valve body and a lower valve body, wherein the upper valve body and the lower valve body are in flange connection, and the valve is characterized in that the upper valve body is a rotating horizontal moving valve, the lower valve body is an air bag sealing valve, and a middle stock bin is arranged between the upper valve body and the lower valve body. The compression air bag sealing double-layer ash discharging valve has the advantages that the lower valve body of the double-layer ash discharging valve is a swing type flat valve, valve plates are of a double-layer structure, a compression rubber air bag is arranged between the upper valve plate and the lower valve plate, when the lower valve body is closed, the upper valve plate is in contact with the upper valve plate and the lower valve body, the effects of stopping and blocking materials are achieved, the lower valve body continues to be closed, and therefore the lower valve plate compresses the middle rubber air bag, the air bag is deformed to be in tight contact with the lower valve body and the upper valve body, forced sealing is achieved between the upper valve plate and the upper valve body, and between the lower valve plate and the lower valve body, and due to the sealing mode, the non-sealed combined face caused by machining errors and initial abrasion can be compensated, and the discharging valve has the advantages of being good in sealing performance and small in mechanical abrasion.

Description

technical field [0001] The invention belongs to valves, in particular to a double-layer ash unloading valve with upper and lower sets of valves. Background technique [0002] At present, most of the large flue ash discharge systems of sintering machines use mushroom head type double-layer ash discharge valves or plug-in type double-layer ash discharge valves. The common disadvantage of these two types of ash unloading valves is that the mushroom head or insert plate (sealing strip) is easily worn under the scouring action of sintering particles, resulting in air leakage that seriously affects the output of the sintering machine and greatly shortens the service life of the equipment. . Through the observation of the use of the double-layer ash discharge valve, it is believed that the main reasons for the serious air leakage and shortened life of the double-layer ash discharge valve are: 1. The sintered particles scour the valve plate (mushroom head) during the falling proces...
