Dust remover lifting offline valve capable of preventing valve plate from accidentally falling

Abstract

The invention provides a dust remover lifting offline valve capable of preventing a valve plate from accidentally falling. The dust remover lifting offline valve comprises a lifting air cylinder, an air cylinder fixing support, a lifting valve rod and an offline valve plate and is suitable for the field of dust remover offline valves and the like. The dust remover lifting offline valve capable of preventing the valve plate from accidentally falling is mainly characterized in that a wedge block device capable of preventing the valve plate from accidentally falling is additionally arranged on an existing lifting offline valve, so that the valve plate of the lifting offline valve in an open state is protected, and an accident that the valve plate of the pneumatic lifting offline valve accidentally falls, air outlets of chambers of a dust remover are closed, and resistance of the dust remover is accidentally increased under unforeseen circumstances such as a start air source pipeline fault, an electromagnetic valve fault and low valve plate lifting air source pressure caused by the fact that the air cylinder of the lifting offline valve is lifted can be avoided. According to the dust remover lifting offline valve, the accident that the valve plate of the pneumatic lifting offline valve probably accidentally falls can be avoided when the dust remover works normally, so that operation safety of a dust remover body is effectively guaranteed.

Description

technical field [0001] The invention relates to equipment related to dust collectors, in particular to a lift-type off-line valve used in dust collectors (suitable for dust collector air outlet valves, etc.). Background technique [0002] On the dust collector, in order to evenly distribute the airflow of the dust removal system to each dust removal room and also to achieve the purpose of offline cleaning and offline maintenance of each dust removal room, each dust removal room of the dust collector needs to be equipped with an offline air outlet valve . During the opening and use of the valve, due to accidents such as the failure of the pneumatic lift off-line valve cylinder to lift and open the air source pipeline, the failure of the solenoid valve, and the low pressure of the valve plate lift air source, the valve plate of the pneumatic lift off-line valve is under the action of its own gravity. It will fall automatically, so that the air outlets of each chamber of the d...

AI Technical Summary

Problems solved by technology

During the opening and use of the valve, due to accidents such as the failure of the pneumatic lift off-line valve cylinder to lift and open the air source pipeline, the failure of the solenoid valve, and the low pressure of the valve plate lifting air source, the valve plate of the pneumatic lift off-line valve is under the action of its own gravity. It will fall automatically, so that the air outlets of each chamber of the dust collector will be closed, which will easily cause dangerous accidents in the dust collector

[0003] In order to improve the safety and reliability of the dust collector operation, it is necessary to solve the phenomenon that the valve plate of the pneumatic lifting off-line valve automatically falls automatically
