Temperature-resistant series-connecting air locking relay valve

Abstract

A temperature-resistant series-connecting air locking relay valve comprises a relay valve upper flange, an outer shell, an inner hole thread, connecting screw holes, an ash discharging channel inclined hole, a lower outer thread, a flashing ash discharging plate, a series pin, a transverse pin, a crank arm, a nose-shaped worm hole, a counterweight iron shaft, counterweight iron and a lower flange, and is characterized in that the the screw holes are formed in the relay valve upper flange; the inner hole thread is formed in the center of the relay valve upper flange through turning and used for the butt joint of two relay valves; the ash discharging channel inclined hole is formed in the relay valve outer shell; the flashing ash discharging plate is pressed on the inclined hole; rear double lugs are arranged on the back of the flashing ash discharging plate is provided with double rear lugs; the flashing ash discharging plate is connected in series with the crank arm; the upper end of the crank arm is connected into the nose-shaped worm hole at the upper part through transverse pin and fixed through a pin; the part, extending out of the relay valve outer shell, of the transverse pin is equipped with the counterweight iron, and thus the position for matching is convenient to select; the inner hole of the lower-end flange is provided with a thread and can be matched with the upper flange in a screwing manner; in order to reduce the high-temperature thermal deformation of the relay valve body, the one-time integral forming of cast iron is adopted; and in the relay valve series-connecting process, the upper relay valve and the lower relay valve are in flanged connection with each other, one flange is matched with the lower relay valve in a screwing manner, and then the two relay valves are successfully connected in series.

Description

technical field [0001] A temperature-resistant series air-locking relay valve belongs to the technical field of dust removal machinery and equipment. Background technique [0002] The dust discharge valve used in the dust collector requires that the dust outlet must have a strict air lock function in addition to being able to discharge the dust, and cannot leak gas into the dust collector, otherwise, the dust removal effect will be reduced. For example, cyclone dust collector, bag filter, dust collector, electrostatic precipitator, etc.; dust removal equipment with relatively high working environment temperature has stricter requirements for relay valves. It will be higher, and the existing various relay valves, including double relay valves, are difficult to meet the above requirements. Contents of the invention [0003] In order to solve the above problems, the present invention designs a temperature-resistant series air-lock relay valve. [0004] In order to solve the...
