Abstract
The utility model relates to a device improving flue connection stress. Because a direct welding mode is generally adopted by a common flue connection device, a stress-bearing body is often pulled and cracked because of an overweight and overlarge flue, and accordingly a pipe in a boiler bursts or a welded joint is pulled open, air and smoke in the boiler leak, smoke discharge loss is increased, efficiency of the boiler is reduced, operation environment of a boiler room is affected, and unnecessary boiler shutdown maintenance loss is caused. The device improving the flue connection stress comprises an inner steel plate and an outer steel plate, wherein a sealing material is arranged between the inner steel plate and the outer steel plate, and a connection flange is arranged on one side of the outer steel plate. The device improving the flue connection stress is simple in structure and convenient to use, and can prevent the pipe in the boiler from bursting and prevent the welded joint from being pulled open.
Description
Technical field
The utility model relates to a kind of device that flue connects stress that improves.
Background technology
The general directly mode of welding that adopts of common flue jockey, it is, excessively ambassador pressurized body drawing crack overweight because of flue often, cause the boiler booster or draw back weld seam, make the boiler leakage cigarette that leaks out, increase flue gas loss, boiler efficiency reduces, and has influenced the running environment of boiler room, causes unnecessary shutdown maintenance loss.
The utility model content
The purpose of this utility model provides a kind of device that flue connects stress that improves, and it is simple in structure, easy to use, can prevent the boiler booster or draw back weld seam.
For achieving the above object, the technical scheme that the utility model provides is: a kind of device that improves flue connection stress, steel plate and outer steel plate in comprising is characterized in that: be provided with encapsulant between steel plate and the outer steel plate in described, a side of described outer steel plate is provided with adpting flange.
Described encapsulant is heat-insulating material.
Described adpting flange is angle steel flange.
Compared with prior art, the utility model has the advantages that: the utility model acts directly on the boiler body to solve the overweight active force of connection flue, pulls membrane wall or drawing crack weld seam, the purpose of cigarette prevents from leaking out, it can be assembled and dispatch from the factory, and is easy for installation, and operating maintenance is also convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model;
Description of reference numerals: 1-interior steel plate, 2-outer steel plate, 3-encapsulant, 4-adpting flange.
The specific embodiment
Referring to Fig. 1 and Fig. 2: a kind ofly improve the device that flue is connected stress, steel plate 1 and outer steel plate 2 in comprising, be provided with encapsulant 3 between steel plate 1 and the outer steel plate 2 in described, described encapsulant 3 is heat-insulating material, and a side of described outer steel plate 2 is provided with adpting flange 4.
The utility model is used for the yellow phosphoric tail gas boiler first, owing to contain certain corrosive gas in the yellow phosphoric tail gas, for preventing revealing, ad hoc this device of having made is made up of inside and outside two-layered steel plates, interior steel plate 1 directly welds mutually with boiler body, outer steel plate 2 welds with being connected flue, and an angle steel flange is reserved in the outer end, is related with the external world, middle adopt the heat-insulating material sealing, can eliminate flue because of overweight excessive to boiler body or and boiler body between weld seam between stress.
