Abstract
The utility model relates to an FW honeycomb type sealing structure with adjustment function, which comprises a small sealing back arc, a sealing ring and a sealing surface; wherein at least one side of the outer circle of the sealing ring is provided with the small sealing back arc; and the inner circle of the sealing ring is provided with the sealing surface. The utility model is characterized in that both ends of each arc section of the small sealing back arc are provided with lug bosses. The utility model has the advantage that steam (gas) seal can be precisely, easily and rapidly adjusted.
Description
Technical field
The utility model relates to a kind of FW honeycomb sealing configuration with adjustable function, can be used for vapour (gas) sealing, belongs to the turbomachinery field of sealing technology.
Background technique
Because the FW honeycomb sealing configuration of existing vapour (gas) sealing, it is big to adjust workload in maintenance and installation process, and it is very low to adjust precision.As Fig. 1, shown in 2, be former common FW honeycomb sealed structural representation, the FW honeycomb sealing configuration of existing vapour (gas) sealing comprises the little back of the body arc 1 of sealing, seal ring 2 and sealing surface 5, have at least a side to be provided with the little back of the body arc 1 of sealing in the outer ring of seal ring 2, inner ring is provided with sealing surface 5, in installation and maintenance process, as find that sealing surface 5 can not reach usage requirement, then by first little back of the body arc surface of contact 3 and second little back of the body arc surface of contact 4 is handled, workload is big, and handle inhomogeneously, finally cause sealing surface 5 can not accurately reach usage requirement, thereby cause the Security that leakage loss increases and influence is used of medium.
Summary of the invention
The purpose of this utility model provide a kind of can be accurate, simple and direct, the FW honeycomb sealing configuration with adjustable function of rapid adjustment vapour (gas) sealing.
For realizing above purpose, the technical solution of the utility model provides a kind of FW honeycomb sealing configuration with adjustable function, comprise sealing little back of the body arc, seal ring and sealing surface, have at least a side to be provided with the little back of the body arc of sealing in the outer ring of seal ring, inner ring is provided with sealing surface, it is characterized in that, be provided with convex at the place, two ends of each segmental arc that seals little back of the body arc.
The utility model seals the thickness of the little back of the body arc of place, two ends change segmental arc of each segmental arc at the FW honeycomb, form two adjustment convexes that can be used for adjusting vapour (gas) sealing radial clearance, like this when maintenance and installation are used for the FW honeycomb sealing of vapour (gas) sealing, can carry out accurate, simple and direct, processing fast to adjusting convex, thereby make the radial clearance of sealing surface, reach accurate usage requirement.
The utility model has the advantages that can accurate, simple and direct, rapid adjustment vapour (gas) sealing.
