Electro-hydraulic gate valve

Abstract

The invention discloses an electro-hydraulic gate valve and relates to the structure of a control valve on a flue gas pipeline of a dust removal system. The gate valve comprises a frame, wherein the frame comprises two vertical plates, a first transverse plate, a second transverse plate and two middle plates; an insertion plate is arranged between the two middle plates; multiple groups of paired guide rails are connected onto the first transverse plate and the two vertical plates between the first transverse plate and one middle plate and between the first transverse plate and the other middle plate respectively; pressure plates are arranged on the two guide rails in each group respectively; inner sealing members are arranged between the guide rails and the corresponding pressure plates respectively; the guide rails, the inner sealing members and the pressure plates are connected through fastening bolts respectively; adjusting holes are formed in the inner sealing members respectively; supporting frames are fixedly connected onto the middle plates respectively; two outer sealing members and two pressure blocks are arranged between the two supporting frames respectively; a cover plate is connected to one side of each supporting frame far away from each middle plate; adjusting bolts are connected onto the cover plates by threads respectively; and the free ends of the adjusting bolts are arranged on the corresponding pressure blocks in a contact way respectively. The electro-hydraulic gate valve has a good sealing effect.
