Abstract
The utility model provides an improved inspection door installed on a boiler device. A method mainly includes that second flat iron (4) is welded around the inner edge of an angle iron door frame (2) of an original device casing (1) through electric welding, first narrower flat iron (3) is welded around the door frame plane at an interval of an asbestos packing with the welded flat iron through electric welding, an asbestos packing (7) is placed between the two flat iron, finally angle iron (6) is welded into a rectangular shape capable of being just pressed on the asbestos packing on the door sheet, and a bolt (5) is installed into the original screw hole to press the door plate tightly. The inspection door has the advantages that the improving method is simple, the inspection door is easy to produce and convenient to assemble and disassemble without wind leakage.
Description
Technical field
The utility model patent relates to the device on a kind of boiler plant, and it is mounted on the boiler plant, is a kind of follow-on inspection door, its easy accessibility, and good airproof performance can reduce effectively and leak out.
Background technology
In order checking conveniently, need many inspection doors are installed, but thumping majority inspection door structure to be very simple, directly makees doorframe with angle iron, makees door-plate with a block plate in addition on the boiler plant, around door, to install many screws in order preventing leaking out additional and to fix.Door-plate can be out of shape under the high-temperature flue gas heating, and the screw on the door is heated and also is difficult to remove, when each inspection, all to screw be sliced off with gas cutting, thus time-consuming expensive, and sealing is also tight inadequately.This patent is exactly to the problem that exists; Design a kind of follow-on inspection door, it installs a circle asbestos packing additional around doorframe does encapsulant, seals with the angle bar limit; Fixedly inspection door is as long as just can play reinforcing and sealing function with several screws; So easy accessibility is simple in structure, good airproof performance.
Summary of the invention
The utility model patent proposes a kind of modified inspection door that is contained on the boiler plant, and concrete grammar is: on the angle iron doorframe (2) of original equipment housing (1), add electric welding with band iron 2 (4) and around the inner edge of doorframe, weld a circle.Use narrower band iron 1 (3) again; Keep the spacing of an asbestos packing to weld a circle with the band iron that has just welded around in upper edge, doorframe plane, between two limit band irons, put an asbestos packing (7), use angle iron (6) welding a rectangle at last at door-plate with electric welding; Size will just in time can be pressed on the asbestos packing; In original screw hole, load onto bolt (5), door-plate (8) is compressed, till not leaking out.
This patent beneficial effect is to improve one's methods simply, makes easily, and easy accessibility does not leak out.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this patent is described further.
Fig. 1 is that original inspection door is installed the connection elevational schematic view.
Fig. 2 is that new follow-on inspection door is installed the connection elevational schematic view.
Fig. 3 is that new follow-on inspection door is installed cutaway view.
(1) among the figure, housing, (2), angle iron doorframe, (3), band iron 1, (4), band iron 2, (5), bolt, (6), angle iron, (7), asbestos packing, (8), door-plate.
The specific embodiment
Utilize original inspection door, on its angle iron doorframe, around the inner edge of doorframe, enclose in electric welding weldering one with band iron 2.The band iron that keeps around in upper edge, doorframe plane just having welded with the narrower band iron 1 more just in time spacing of an asbestos packing welds a circle with electric welding; Between two limit band irons, put an asbestos packing; On door-plate, weld a rectangle with angle iron at last, size will just in time can be pressed on the asbestos packing, in original screw hole, loads onto bolt; Door-plate is compressed, till not leaking out.
Claims (1)
1. follow-on inspection door; It is characterized in that: on the angle iron doorframe (2) of original equipment housing (1), add electric welding with band iron 2 (4) and around the inner edge of doorframe, weld a circle together, use narrower band iron 1 (3) again; Keep the spacing of an asbestos packing to weld a circle with the band iron that has just welded around in upper edge, doorframe plane with electric welding; Between two limit band irons, put an asbestos packing (7), use angle iron (6) welding a rectangle at door-plate at last, size will just in time can be pressed on the asbestos packing; In original screw hole, load onto bolt (5), door-plate (8) is compressed.
