Abstract
The utility model discloses a flue gas switching valve. The flue gas switching valve comprises a flue gas channel, an exhaust gas channel and an access door, wherein the flue gas channel and the exhaust gas channel are adjacent square pipelines, a valve body which is in pneumatic control is installed between the two channels, the valve body is used for controlling switching of the two pipelines, meanwhile, the access door is arranged on the pipelines, sealing conditions of the valve body can be checked, and the valve body can be rapidly opened to carry out overhauling. According to the flue gas switching valve, the number of valves is reduced, sealing performance of the flue gas switching valve is improved, and overhaul is convenient.
Description
Affiliated technical field
The utility model relates to a kind of flue gas switch valve.This device is mainly used in box-type accumulation of heat incinerator.
Background technique
At present, box-type accumulation of heat incinerator adopts pneumatic valve to control, what generally adopt all is hard sealing, valve plate is easy to distortion after collision, cause gas leak phenomenon, need the valve completely knocked down during valve maintenance, workload is bigger, exhaust pipe and flue gas pipeline adopt independent valve control simultaneously, and valve quantity is more.
The model utility content
In order to overcome existing issue, the utility model provides a kind of flue gas switch valve, and this device is in the same place waste gas and flue gas inlet valve combination, reduced valve quantity, soft seal is all adopted in all sealings of valve, has strengthened the sealing of valve, simultaneously at valve access door is housed, maintenance is convenient.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of flue gas switch valve, it comprises flue gas channel, exhaust steam passage and access door, flue gas channel is adjacent square pipe, the valve plate in the rotating shaft of being fixed on of pneumatic control is housed in the middle of two pipelines, on two pipelines, be provided with access door, the angle of two valve plates of pneumatic valve is 90 degree, the valve plate of pneumatic valve is welded in the rotating shaft, rotating shaft by bearing fixing in two pipeline neutral positions, adopt soft seal between rotating shaft and the pipeline dividing plate, adopt soft seal between valve plate and the pipeline, clear glass is housed on the access door, access door fixes on the pipeline with hinges fixing, adopts soft seal between access door and the pipeline.By the Pneumatic actuator rotating shaft, valve plate is rotated, a pipeline is opened, another closedown of pipeline utilizes a valve to control the switch of two-way pipeline like this; On pipeline, be provided with access door, clear glass is housed on the access door, inspecting valve door sealing situation at any time, access door fixes on the pipeline with hinges fixing, can easily open, and adopts soft seal between access door and the pipeline.
The beneficial effects of the utility model are, have reduced valve quantity, have strengthened the sealing of valve, and maintenance is convenient.
