Abstract

The invention discloses an automatic alignment lift valve comprising a valve plate and a cylinder, wherein the valve plate and a bin gate are opened and closed by the cylinder; the lower part of the cylinder is a cylinder rod which is connected with a ball connecting rod; the ball connecting rod and the valve plate are movably connected; the bin gate is provided with a valve seat; and a contact surface between the valve seat and the valve plate is arranged to be tapper. The valve plate of the invention can automatically align the valve seat in the falling process and has favorable sealing property and stable operation.

Description

Technical field [0001] The invention relates to a lift valve on the bin door of a bag type dust collector, in particular to a self-aligning lift valve. Background technique [0002] At present, when the bag filter is cleaned off-line, a lifting valve is generally used for opening and closing the door of the bag filter. A round hole is opened on the door of the bag filter, and the hole is connected with a circular valve plate. Matching, and then the cylinder pushes the valve plate up and down to realize the opening and closing. Due to the errors in the production and installation of this poppet valve, the valve plate often cannot automatically align the round hole well, and it is also difficult to achieve good sealing due to the unevenness of the valve plate and the dust collector door. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a self-aligning poppet valve, the valve plate can automatically align the valve...
