Abstract
The utility model discloses a double sealing elevation valve for an impulse bag type dust removing system. The double sealing elevation valve for the impulse bag type dust removing system comprises a valve seat, a valve plate, an air cylinder and a piston of the air cylinder. The air cylinder is installed on a top plate of a valve body. A valve seat seal ring is arranged outside the valve seat and connected with a bottom plate of the valve body in a encircled mode through a hoop. The double sealing elevation valve for the impulse bag type dust removing system is characterized in that a press angle iron ring and a valve plate angle iron ring are arranged on the valve plate. The lower end of the valve plate angle iron ring is connected with a U-shaped seal ring in a matched mode. The double sealing elevation valve for the impulse bag type dust removing system can effectively improve seal in closing a valve and prevent smoke with dust from entering an air circulating system pipeline and polluting environment.
Description
Technical field
The utility model relates to a kind of pulse bag-type dust-removing, is specifically related to a kind of pulse bag-type dust-removing system double-sealing poppet valve.
Background technique
At present, bag-type dust removing system causes the deduster dewfall when low for preventing from crossing because of flue-gas temperature, and corrosion deduster and paste bag, usually adopt from dust catcher gas purifying chamber extraction pure qi (oxygen) and heat through circulating hot wind stove, hot blast after the heating is sneaked into system's flue gas, make the deduster normal operation, but the hot air circulating system of namely must stopping using after the deduster normal operation, need hot air circulating system pipe valve tight closing, but because currently used poppet valve only arranges Sealing one at valve seat, be not closed completely close, make ash-laden gas enter the air circulating system pipeline, entered in the atmosphere by the system fan extraction, thus befouling environment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pulse bag-type dust-removing system double-sealing poppet valve, and the leakproofness of double sealing Effective Raise valve closing prevents that ash-laden gas from entering the air circulating system pipeline and befouling environment.
The technological scheme that the utility model technical solution problem adopts is: a kind of pulse bag-type dust-removing system double-sealing poppet valve, comprise valve seat, valve plate, cylinder, cylinder piston rod, described cylinder is installed on the valve body top board, described valve seat is provided with valve seat insert outward, and hold tightly with the valve body base plate by anchor ear and to be connected, it is characterized in that: be provided with at described valve plate and compress angle ring and valve plate angle ring, the lower end of described valve plate angle ring is connected with U-shaped seal ring coupling.
As further improvement, be provided with self-locking device in the described cylinder, namely when the pressurized air air supply system breaks down (dying), cylinder produces self-locking automatically, institute's bringing onto load can not fall under action of gravitation or be mobile, be that the poppet valve valve plate can not fall automatically because of deadweight, simple in structure, reliable operation.
In the utility model, in order to guarantee the seal request of valve, be provided with Sealing at valve seat and valve plate respectively, wherein the seal height of valve seat will be higher than respectively the height of valve body and anchor ear.
The beneficial effects of the utility model are: in order to guarantee the seal request of valve, seal arrangement is set respectively on valve seat and valve plate, the double sealing Effective Raise valve leak, prevent ash-laden gas bleed air circulating system pipeline and befouling environment.
