The utility model aims to provide a normally open type dust remover lifting valve device, which comprises a dust remover, wherein an air cylinder is arranged at the top of the dust remover, a horizontal partition plate for dividing a dust removing cavity into a purified gas channel and an upper box body is arranged in the box body of the dust remover, and a through hole in the vertical direction is formed in the partition plate; the purifying gas channel is positioned below the upper box body, and a cylinder rod of the cylinder vertically penetrates into the upper box body downwards; the inner diameter of the through hole is larger than the outer diameter of the cylinder rod, and the lower end of the cylinder rod is connected with a round sealing plate; the outer diameter of the sealing plate is larger than the inner diameter of the through hole, and the sealing plate and the through hole are in coaxial relation; m transmission rods are arranged on the upper surface of the sealing plate, M is a natural number greater than 1, and the transmission rods are parallel to the cylinder rods; the upper end of the transmission rod sequentially passes through the top of the dust remover and the elastic element and is fixedly connected with the limiting plate.
The utility model has the advantages and positive effects that:
according to the utility model, the poppet valve is in an open state by utilizing the elasticity of the external elastic element, and is in a closed state by utilizing compressed air, and because the elastic element is in a separated state with the cylinder body and the cylinder rod does not pass through the cylinder top cover, one (the cylinder fixed cover hole and the cylinder rod) dynamic sealing point is reduced, and the consumption of air leakage and sealing rings at the position is reduced. And because the spring is arranged on the rod piece outside the air cylinder, a plurality of sets (rod and spring) can be arranged, and the safety and the reliability are higher. The traditional scheme can only set up a set of at the cylinder pole top, and the technical scheme of this application has higher reliability, can adopt standard unilateral output cylinder simultaneously.
