Abstract

The invention relates to a lift valve centering device. The device comprises a centering part base, a base support, a centering part and a centering part pressing plate, the centering part comprises three layers of PTFE shaft sleeve rings, each layer of PTFE shaft sleeve ring is formed by splicing of two semi-ring structures, a bolt hole is formed in the centering part, the centering part base iscomposed of a center ring steel plate and wing plates, the multiple wing plates are evenly mounted on the periphery of the center ring steel plate, bolt holes are formed in the center ring steel plateand the wing plates, the center ring steel plate is located below the centering part, the base support is arranged at the position, above the wing plates, of the centering part base, one end of the base support is welded to an equipment cylinder wall, the other end of the base support is connected and fixed with the wing plates of the centering part base through angle iron bolts, angle iron nutsand angle iron gaskets, and the lift valve centering device has the beneficial effects that the centering part is a ring composed of two half rings, during overhauling, under the condition that a liftvalve structure is not affected, the centering part is directly replaced, and the convenience is provided for continuous stable production.

Description

technical field [0001] The invention relates to the fields of bag filter and regenerator incinerator, in particular to a centering device for a poppet valve. Background technique [0002] Poppet valve is generally composed of valve plate, valve stem and driving device, etc. It is mainly used to close the air inlet of some small chambers in the equipment, and is widely used in electric power, petrochemical and other industries. In the past, poppet valves were mostly composed of bonnet, valve stem and driving device. When the stroke of the poppet valve is long, the coaxial ratio of the valve stem and valve seat is difficult to guarantee, and there is a hidden danger of eccentric leakage, which will easily affect the continuous and stable operation of the equipment. influences. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide a poppet valve centering device, and solve the problem that the coaxia...
