Description
Technical field
The utility model relates to a kind of deduster bypass valve, is specifically related to a kind of band winding-up bypass valve of deduster.
Background technology
At present; in medical waste smoke gas treatment engineering; when cigarette temperature exceedes the temperature range that filter bag can bear; or filter bag pressure reduction is when being greater than setting value and can not falling; often take to arrange bypass protection; now bypass valve is opened automatically, and the terminal valve of sack cleaner is closed, and flue gas is directly discharged to chimney through air-introduced machine.Effective protection is played to sack cleaner.Therefore; what adopt the bypass valve of bypass protection measure is tightly very important; existing bypass valve generally all also exists poor sealing performance, valve inner fouling phenomenon is serious, cause leaking air in running phenomenon, thus the equipment that affects normally works and discharges problems such as exceeding standard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of band winding-up bypass valve of deduster, set up blowing device, effectively can remove dust stratification, and overall sealing performance is good.
The technical scheme that the utility model technical solution problem adopts is: a kind of band winding-up bypass valve of deduster, comprise cylinder, connecting rod, valve body, valve plate, air inlet, air outlet and bypass air outlet, described cylinder is arranged at body top, and be connected with valve plate by connecting rod, black box is provided with between described cylinder and valve body, upper plate and lower shoe is provided with in described valve body, annular blast pipe is provided with between described upper plate and lower shoe, described annular blast pipe is provided with some injection holes, described annular blast pipe is connected with a point gas tank by tube connector, described point of gas tank side is provided with pulse valve, described point of gas tank is connected with support by U-bolt.
As further improvement, described upper plate and lower shoe place are equipped with " 9 " font seal and back-up ring.
The beneficial effects of the utility model are: lead between upper plate in valve body and lower shoe and be provided with annular blast pipe, effectively can remove dust stratification, and overall sealing performance is good.
