Description

Knife gate valve for powder

Technical Field

The utility model relates to a knife gate valve, in particular to a knife gate valve for powder.

Background

The existing dry dust removing system mainly comprises a filtering system, wherein semi-clean gas subjected to gravity dust removal is introduced into a cloth bag box body and filtered by a filter bag, so that the dust content in the gas is reduced to below 10mg/Nm < 3 >. The semi-clean raw gas from the gravity dust collector enters the lower box body of the bag type dust collector through the branch pipe, the dust-containing gas upwards reaches the cloth bag for filtering, fine dust is attached to the outer surface of the filter bag through filtering, the purified gas is collected to the upper box body through the filter bag, and the purified gas is sent out through the clean gas branch pipe and the main pipe.

The knife gate valve can cut off the medium, so that the valve is closed without being blocked by the medium, and the knife gate valve is more used in dry dedusting and often bears the ash discharging function. The existing hidden rod type knife gate valve is free of sealing tape partition between a valve channel and a valve cover inner cavity, and powder particles can be filled in the valve cover inner cavity after long-term use, so that the valve is blocked and cannot be normally opened and closed. If the valve is required to be detached from the pipeline in normal use, then the valve is disassembled to clean the inner cavity of the valve cover, the valve with the structure is unfriendly to use experience, and the valve is large in workload and high in difficulty in maintenance.
