Temperature-resistant series-connected air-locking relay valve

Abstract

A temperature-resistant series-connected air-locking relay valve comprises a relay valve upper flange, a casing, inner hole threads, connecting screw holes, an ash discharging channel inclined hole, lower-end outer threads, a flashing ash discharging plate, a clustering pin, a lateral pin, a connecting lever, a nose-shaped helical hole, a counterweight iron shaft, counterweight iron and a lower-end flange. The relay valve is characterized in that the screw holes are formed in the relay valve upper flange, and the inner hole threads are turned in the centers and are used for butt-jointing of two relay valves; the ash discharging channel inclined hole is formed in the relay valve casing; the flashing ash discharging plate presses against the inclined hole, a back dual-lug is arranged at theback and is in series connection with the connecting lever, the upper end of the connecting lever is connected in the upper nose-shaped helical hole through the lateral pin and is fixed by a pin, andthe part extending out of the relay valve casing, of the lateral pin is equipped with the counterweight iron, so that the matching position is convenient to select; threads are formed in inner holes of the lower-end flange; and the lower-end flange can be rotationally matched with the upper flange. One-time integrated forming of cast iron is adopted to reduce high-temperature thermal deformation of relay valve bodies, when the relay valves are connected in series, the upper relay valve and the lower relay valve are in flange connection, the lower relay valve is rotationally matched with one flange, and the two relay valves are connected in series successfully.

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...
