Description
Technical field
The utility model relates to seal arrangement, especially a kind of preceding shaft sealer for out of stock air door.
Background technique
Antipollution significance has been carried as worldwide problem shrilly.Along with development and the growth in the living standard that modern industry is produced, the problem that pollution of atmosphere has become people extremely to pay close attention to.
Seal arrangement is the vitals of air door, and it is applied in denitrating flue gas and the flue gas dust collecting system, and its effect is to realize isolating the shutoff flue gas.Out of stock air door adopts the double-deck baffle arrangement of louvre type, feed sealing wind during shutoff between the double-deck baffle plate, and this device interior contains a large amount of harmful gases, if this gas is discharged in the atmosphere and will produces destruction to environment.
The model utility content
The applicant is at having noxious gas emission in atmosphere in the above-mentioned existing production technology; the shortcoming of befouling environment; a kind of preceding shaft sealer of out of stock air door rational in infrastructure is provided; thereby out of stock air door is sealed; effectively control discharge of harmful gases; play the effect of protection environment, good reliability.
The technological scheme that the utility model adopts is as follows:
A kind of preceding shaft sealer of out of stock air door comprises the front axle sealing seat, and described front axle sealing seat middle part has stepped bore, has a plurality of tapped holes on the toroidal surface of described front axle sealing seat; Gland retainer plate before install by filler at the stepped bore step place of described front axle sealing seat, described preceding gland retainer plate is connected with the front axle sealing seat by a plurality of first bolts; Be positioned on the outer peripheral surface of front axle sealing seat and also be provided with step, described step place is equipped with flange, and described flange is connected with air door by second bolt.
As further improvement in the technical proposal:
The structure of gland retainer plate is before described: gland retainer plate becomes " T " font structure before described, and its middle part has second through hole, evenly has four first through holes that first bolt is installed on its toroidal surface;
The structure of described flange is: described flange squarely structure, and described flange middle part has fourth hole, also has four third through-holes that second bolt is installed on the described flange;
Described filler adopts the Expanded graphite ring.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, and is easy for installation, is installed on the air door place by the utility model, can effectively play sealing effect, prevents discharge of harmful gases, plays the effect of protection environment, good reliability, and cost is low.
