Scraper, the both ends of above-mentioned spring are respectively acting on body and connecting cylinder.
In use, connecting cylinder is subject to the pushing of exhaust gas to overcome spring spring to this good antiscale property discharge duct, due to
The flow velocity of exhaust gas is unstable, and connecting cylinder back and forth can be steady by the fouling on the inside of body by scraper thereon in reciprocal moving process
Fixed strikes off.
Certainly, good antiscale property discharge duct when not in use, initial position is under the elastic force effect of spring.Once good antiscale property
After discharge duct use, spring can significantly be shunk.As can be seen that good antiscale property discharge duct is in use and without using two states
Between when switching, scraper can be moved back and forth significantly, strike off intrinsic fouling eventually through scraper.
There is the gear edge protruded in a ring in above-mentioned good antiscale property discharge duct, on the inside of the body, above-mentioned spring
Both ends are respectively acting on gear edge and connecting cylinder.
Gear edge can realize spring end and position.
In above-mentioned good antiscale property discharge duct, there is recessed spring eye, above-mentioned spring is wherein on the connecting cylinder
One end is located at spring eye.
The setting of spring eye can realize stable position to the end of spring.
In above-mentioned good antiscale property discharge duct, above-mentioned spring and spring eye form a Flexible element, and the elasticity is single
The quantity of member is at least three and circumferentially distributed along body central.
In above-mentioned good antiscale property discharge duct, the depth of the spring eye is its length 1/2-3/4.
Such structure can improve the connective stability between spring and connecting cylinder.
In above-mentioned good antiscale property discharge duct, the gear is along upper with the positioning column protruded, above-mentioned another end cap of spring
On positioning column.
Positioning column can be to spring other end stable position.
In above-mentioned good antiscale property discharge duct, the positioning column is an integral structure with gear edge.
In above-mentioned good antiscale property discharge duct, the gear along with body is split structure and both are mutually solid by welding
Even.
In above-mentioned good antiscale property discharge duct, there is plate-like wind shield on the inside of the connecting cylinder.
In the exhaust gas process of circulation in discharge duct, connecting cylinder can be with moving together under the action of wind shield.
In above-mentioned good antiscale property discharge duct, the quantity of the wind shield is several and wind shield along on the inside of connecting cylinder
It is circumferential uniformly distributed.
In above-mentioned good antiscale property discharge duct, the scraper includes the elastic card on the inside of main body and main body in a ring
Foot, above-mentioned card base is located in connecting cylinder and card base and connecting cylinder tight fit connection under the elastic acting force of card base.
Card base itself has elasticity, and under the elastic acting force of card base, card base can be with being stably connected with the inside of connecting cylinder.Due to
Scraper is connected with card base, finally makes being connected on connecting cylinder for whole scraper stabilization.
Compared with prior art, this good antiscale property discharge duct in logical exhaust process with regard to that can will be located within the body side due to tying
Dirt stabilization is struck off, and therefore, its stability is higher.
Meanwhile connecting cylinder, spring and scraper etc. are respectively positioned in body, whole discharge duct fouling is also compact, has
Very high practical value.
