Abstract
The utility model discloses a governing valve added with a seal, which comprises a blow dryer, base bearings, long rotating shafts, short rotating shafts and blades, wherein the base bearings are symmetrically arranged on lateral plates at two sides of the blow dryer of the governing valve, the long rotating shafts and the short rotating shafts are arranged on middles of bearings, the blades are respectively welded between the long rotating shafts and the short rotating shafts, fixing plates and shaft sleeves are uniformly welded on the lateral plates at two sides of the blow dryer, sealing members are embedded on the shaft sleeves, and sealing covers are externally connected to the shaft sleeves. The governing valve has a reasonable structure, is safe and reliable in property, can be effectively prolonged in service life and maintenance period and is mainly applied to irritated and corrosive gases such as smoke and process gas.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of adjustment doors that adds sealing.
Background technique
The blower fan product in the mine, sector application such as metallurgy, cement, iron and steel, power plant is extensive, is indispensable key equipment.Blower fan is when fed sheet of a media, and great role is played in the adjusting of air door.When applying to medium and be excitant, corrosive gass such as flue gas, process gas; Because excitant, corrosive gas can damage the bearing of adjustment doors; Cause the air door can not normal regulating; Thereby make blower fan in required range of flow, normally not move the serious consequence
that this situation can cause whole system to work.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, and a kind of adjustment doors that adds sealing of rational in infrastructure, long service life is provided.
Technological scheme: a kind of adjustment doors that adds sealing; Comprise air duct group, rolling bearing units, long rotating shaft, short rotating shaft, blade, on the both sides side plate of the air duct group of adjustment doors, be symmetrically arranged with rolling bearing units, in the middle of bearing, be provided with long rotating shaft and short rotating shaft; Be welded with blade respectively between long rotating shaft and the short rotating shaft; Evenly welded fixed plate and axle sleeve on the side plate of said air duct group both sides, studded with Sealing on the said axle sleeve, axle sleeve is externally connected with sealing cover.
The Sealing of inlaying on the said axle sleeve is a carbon fibre dipping teflon braided packing Sealing, and fixed plate separates bearing support and axle sleeve, and the axle sleeve that is embedded with Sealing connects sealing cover and can stop leaking of gas effectively, has protected bearing.
Beneficial effect: the utility model is rational in infrastructure, and performance is safe and reliable, can effectively prolong the working life and the repair cycle of adjustment doors, mainly applies to the Fan Regulation door that medium is excitants such as flue gas, process gas, corrosive gas.
