Abstract
The utility model relates to an angular deviation adjuster of a circular duct. The angular deviation adjuster of the circular duct is used for adjusting angular deviation caused by errors of manufacturing and mounting in civil defence engineering contamination areas. The angular deviation adjuster comprises an A air hose 1 and a B air hose 2. The diameters of the A air hose and the B air hose are the same. The A air hose and the B air hose are respectively provided with a vertical end face and a bevel end face, the bevel end faces of the A air hose and the B air hose are rightly opposite, and the slopes of the A air hose and B air hose are the same. The vertical end faces and the bevel end faces of the A air hose and the B air hose are respectively fixedly connected with vertical flanges and taper flanges. At least two C-shaped chucks 8 are arranged on the connecting portions of the taper flanges in an evenly distributing mode, the C-shaped chucks 8 clamp the taper flanges, and a rubber gasket 7 is arranged between the two taper flanges so that a left air hose 1 and a right air hose 2 can be fixedly connected and form different angles which are equal to or smaller than 180 degrees. The angular deviation adjuster of the circular duct is high in manufacturing and mounting efficiency so that construction period is saved; lowers potential safety hazards in site; is simple in structure, low in cost and strong in adaptability after the angular deviation adjuster is pre-manufactured; and is convenient to use, low in technical requirement and convenient to popularize and use in a wide range.
Description
Technical field
The utility model relates to a kind of circular duct augular offset regulator, relating in particular to a kind of being applied to adjusts in civil defence (people's air defense) the engineering chemical contaminated zone because the circular duct angle adjuster of making and augular offset that alignment error causes belongs to ventilation in wartime mounting technique field.
Background technique
Civil defence (people's air defense) engineering is to adopt that engineering is sheltered to wait the collective protection measure, takes precautions against and alleviates the harm that air strike causes, and protects people's life and property safety.Ventilation in wartime system in civil defence (people's air defense) engineering is the collective protection that guarantees personnel in the engineering, guarantees the inside and outside ventilation of civil defence (people's air defense) engineering, and the system of sheltering personnel's breathing and engineering superpressure required air in the engineering is provided.
A kind of the advancing of chemical contaminated zone, exhaust duct of being arranged on arranged in the ventilation in wartime system at present, adopt 2～3mm Plate Steel welding fabrication, be fixed together by the 8mm Plate Steel flange that is welded on the airduct two ends between each section airduct.When the welding steel flange of airduct two ends, because jig inaccuracy and welding procedure are incorrect, can cause Steel Plate Flange and airduct can not keep vertical during welding; When mounted, because flange and airduct out of plumb, deviation will appear in the follow-up pipeline section that is connected with flange, and the longer departure of follow-up pipeline section is just larger.Reserve an end tube section in the middle of normally adopting at present and do not make, after other pipe fittings all are in place, carry out field fabrication according to the misalignment angle between the two end tube section flanges of reserving therewith the airduct connection again.But there are many defectives in field fabrication:
1, after other pipe fittings all are in place, could determine to reserve the augular offset size of the required adjustment of pipeline section, affect the duration.
2, field fabrication need be employed the special equipments such as electric welding, increases the job site potential safety hazard.
Summary of the invention
The technical problem that the utility model solves is: could determine to reserve the augular offset size of the required adjustment of pipeline section after other pipe fittings all are in place, affect the duration; Field fabrication need be employed the special equipments such as electric welding, increases the job site potential safety hazard.
The utility model provides a kind of circular duct augular offset aligner, comprise A airduct (1), B airduct (2), described A, the B dust diameter is identical, a perpendicular end surface is respectively arranged, an angle end face, described A, the B airduct separately the angle end face over against and gradient identical, perpendicular end surface separately, the angle end face is welded and fixed respectively and connects vertical flange, the angle flange, at least two C clamp heads of the uniform setting in the joint of described angle flange (8), described C clamp head (8) is clamped described angle flange, the rubber washer in interval (7) in described two angle flanges, thus described A airduct (1) is fixedly connected with B airduct (2) and can form≤180 ° different angles.
Described airduct A and airduct B employing thickness are 2 to 3mm steel plate making.
It is the steel plate making of 8mm that described flange adopts thickness.
Described C clamp grease head highness 45mm, width 40mm, thickness 30mm, middle groove width 25mm, top has vertical upper screwed hole, and the bottom has vertically lower tapped hole.
The beneficial effects of the utility model are: making, installation efficiency height, the augular offset regulator can be carried out standardized production, and need to after all being in place, just not make by other pipe fittings, save the duration; Reduce site safety hidden danger, do not need to employ at the scene the special equipments such as electric welding after the standardized production; Simple in structure, cost is low, strong adaptability, after making in advance, can connect accurately at the scene; Easy to use, technical requirements is lower, is convenient to promote the use of on a large scale, and larger Social benefit and economic benefit is arranged.
