Description

Technical Field

[0001] The utility model relates to the technical field of valve locking, in particular to a dust collector outlet valve locking device. Background Art

[0002] The purpose of valve status locking and closing is to ensure safety. During transportation, maintenance or decommissioning, when there is no operator, locking the valve can effectively prevent illegal operation or other reasons from accidentally opening the valve, thus protecting the lives and property of personnel. In addition, valve status locking and closing can facilitate valve design and use, and reduce labor maintenance costs.

[0003] The patent document with the prior art publication number CN218063549U provides a high-low pressure controlled valve locking device and a valve with the locking device. The locking device is mainly composed of a cylinder assembly, a roller assembly and a locking assembly. The cylinder assembly drives the roller assembly to act on the locking assembly according to the collected pipeline pressure, so as to form a connecting rod balance relationship between the roller assembly and the locking assembly to lock the valve when the pipeline pressure is normal, and to destroy the connecting rod balance relationship to unlock the valve when overpressure or underpressure occurs. The valve locking device eliminates the influence of external factors, automatically controls the locking and unlocking of the valve according to the pipeline pressure feedback, and realizes safe production.

[0004] However, during the operation of the dust collector in the feeding system, the outlet baffle of the existing dust collector outlet valve locking device is usually controlled by a lifting cylinder, and the lifting cylinder is supplied with air by the compressed air network. However, when the compressed air network suddenly loses pressure, the outlet baffle will fall due to gravity, causing the purification system to be forced to stop operating. At this time, a large amount of sticky materials begin to fall due to the sudden loss of pressure in the dust collector, which not only affects the production efficiency but also may cause damage to the equipment. For this reason, we propose a dust collector outlet valve locking device. Utility Model Content
