It is equipped with and fills in compatible protruding portion with control.
Protruding portion can play the role of positioning, and the axis of the axis and spacing ring that prevent control plug is inconsistent, causes to control
System plug can not completely close gas passage, cannot effectively prevent suck-back.
Preferably, the spacing ring is provided with sliding slot close to the side of control plug, the control is provided with cunning beyond the Great Wall
It is slided in sliding slot the end of pole, the litter.
Litter and sliding slot also function to the effect of limit, and the axis of the axis and spacing ring that prevent control plug is inconsistent.
Preferably, surface and spacing ring that the control plug is contacted with spacing ring are all provided with close to the side of limit plunger
It is equipped with polytetrafluorethylecoatings coatings.
The lubricity of increase control plug and limit ring surface, reduces the abrasion of the two.
Compared with prior art, the beneficial effects of the utility model are at least one of following：
The flue gas processing device suck-back device of the application is simple in structure, easy for installation, can not change original flue gas
The structure of processing unit, repacking is convenient, reduces cost.
The flue gas processing device suck-back device of the application can effectively prevent suck-back, avoid alkali caused by lye suck-back
Corrosion of the liquid to equipment, extends the service life of equipment, reduces the failure rate of equipment.
