Abstract
The utility model relates to a valve, in particular to a valve for off-line dust cleaning of a bag-type dust collector, which comprises a valve body that is internally provided with a valve shaft being rotatably fit with the valve body, wherein one end of the valve shaft is connected with a power mechanism arranged beside the valve body; a valve plate is fixedly arranged on the valve shaft; and the power mechanism drives the valve shaft to rotate and drives the valve plate to revolve by taking the axis line of the valve shaft as a revolving center, thus enabling the valve plate and the valve body to be in two states of being attached to be sealed or being separated to be opened. Known from the technical scheme, the valve plate is arranged on the valve shaft, and one end of the valve shaft is connected with the power mechanism that provides driving power for the valve plate to do revolving motion by surrounding the axis line of the valve shaft; and as the valve plate does revolving motion, when the power mechanism is broken down, the valve plate does not change under the influence of dead weight and is always in safe running state, thus ensuring the running safety of the whole dust collection system.
Description
Technical field
The utility model relates to a kind of valve, relates to a kind of valve that is used for the sack cleaner off-line ash-clearing specifically.
Background technology
Sack cleaner is generally adopted in the smoke gas treatment of every profession and trade, and how sack cleaner improves the deashing purification efficiency with the off-line ash-clearing mode.Adopt of off-line ash-clearing device gone up the following formula lift valve more at present, last following formula lift valve is under the dynamic action of compressed gas source, valve plate is the track of motion up and down, thereby reach or unlatching or closed condition, this mode is comparatively strict to the requirement of compressed gas source, because cleaner is under normal operating condition, when some bin deashings, this bin is in off-line state, and other bins all are in on-line filtration, when a certain link in the compressed gas source breaks down, last following formula lift valve is under the effect of valve plate self gravitation, be in closed condition, cut off the air-flow of current bin, make current bin be in off-line state, when all last following formula lift valves all are under the under-supply influence of compressed gas source, all valve plates all are in closing state, and the air-flow of whole deduster all is cut off, but simultaneously, the air-introduced machine of cleaner is also in running order, cleaner still is in negative pressure state, and whole dust-removal system is produced very big security threat, when serious even the burning of the dynamo-electric machine that can cause facining the wind; When being under the off-line ash-clearing at a certain bin, owing to the restriction of bin height, the power of negative pressure and the reason of valve plate self, valve plate is easy to generate in the closing movement track and waves, can not close fully, so easy formation aditus laryngis, can not cut off this bin air-flow fully, cause mass air flow excessive, system is produced very big resistance.
Summary of the invention
The purpose of this utility model just provides a kind of valve that is used for the off-line ash-clearing device, and the valve plate of this valve is not subjected to self deadweight and the influence of negative pressure when compressed gas source breaks down, safe.
For achieving the above object, the utility model has adopted following technical scheme: comprise valve body, be provided with the valve shaft that is rotatably assorted with its formation in the valve body, one end of valve shaft links to each other with the actuating unit that the valve body side is provided with, be installed with valve plate on the valve shaft, actuating unit drives valve shaft, and to rotate and drive valve plate be that the centre of gyration turns round with the axis of valve shaft, makes valve plate and valve body be in to recline sealing or separate the unlatching two states.
As shown from the above technical solution, the utility model is by being provided with valve plate on valve shaft, one end of valve shaft links to each other with actuating unit, actuating unit provides valve plate to do the driving force of gyration around the axis of valve shaft, because valve plate is to do gyration, when actuating unit broke down, valve plate was not changed by the influence of its deadweight can like this, all the time be in the state of safe operation, guaranteed the security of operation of whole dust-removal system.
