| description | The utility model discloses a hard-to-hard non-tight-seal dust collector off-line valve. The dust collector off-line valve comprises a disc valve plate, a band steel valve seat and an air cylinder lifting rod. The dust collector off-line valve is characterized in that a horizontal plate is formed on the band steel valve seat, a front resistance-increasing plate and/or a back resistance-increasing plate are/is arranged on the front side and/or the back side of the band steel valve seat, the front resistance-increasing plate and/or the back resistance-increasing plate are/is in sealed and fixed connection with the lower plane of the disc valve plate and in hard-to-hard non-tight-seal contact with the horizontal plate of the band steel valve seat to form sealing surfaces, and the front resistance-increasing plate and/or the back resistance-increasing plate and the band steel valve seat form a resistance-increasing turning-back chamber. The hard-to-hard non-tight-seal dust collector off-line valve has the benefit |
