Abstract
The utility model relates to boiler equipment technical field, a kind of low-pressure tube type waste heat steam boiler with expansion joint specifically, comprise housing and the heating pipe being located at enclosure interior, housing is provided with expansion joint, two ends, expansion joint left and right are provided with ear block, ear block is provided with bolt hole, is connected with bolt between the ear block at two ends, expansion joint left and right, and the two ends, left and right of bolt are equipped with nut and distance between the right and left ear block regulates by nut.The utility model, owing to being provided with expansion joint on the housing of boiler, when heating pipe heating produces deformation, due to the telescopic action of expansion joint, reducing the pulling force that heating pipe deformation produces housing, can extend the working life of steam boiler; The utility model is provided with ear block due to the two ends, left and right at expansion joint, and is bolted two ear blocks, can prevent the phenomenon making expansion joint excessive tensile reset because internal pressure is much, avoids weld between housing and heating pipe to leak because pulling force produces.
Description
Technical field
The utility model relates to boiler equipment technical field, specifically a kind of low-pressure tube type waste heat steam boiler with expansion joint.
Background technique
Expansion joint is also slip joint or corrugated expansion joint traditionally, being utilize effective dilatation of the elastic element of corrugated expansion joint expansion joint to absorb pipeline, conduit or container by reason and a kind of compensation device of the dimensional changes produced such as expanding with heat and contract with cold, belonging to a kind of compensating element.Can to axis, laterally, and the absorption of angular displacement, for pipeline, equipment and system add thermal walking, mechanical displacement absorbs vibration, reduce noise etc.
Existing low-pressure tube type afterheat steam is all do not have expansion joint, the heating pipe of this boiler central authorities after long-time heating can produce certain deformation, because the joint at traditional heating pipe and housing two ends adopts welding, after heating, heating pipe deformation can cause the situation occurring with the weld of housing coming off, and shortens the working life of steam boiler or increases maintenance cost.
Model utility content
The purpose of this utility model is for the problem in background technique, and provide a kind of low-pressure tube type waste heat steam boiler with expansion joint, this boiler is provided with expansion joint on housing, can reduce heating pipe by thermal deformation to housing failure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of low-pressure tube type waste heat steam boiler with expansion joint, comprise housing and the heating pipe being located at enclosure interior, described housing is provided with expansion joint, two ends, described expansion joint left and right are provided with ear block, described ear block is provided with bolt hole, is connected with bolt between the ear block at two ends, described expansion joint left and right, and the two ends, left and right of described bolt are equipped with nut and distance between the right and left ear block regulates by nut.
Further, described expansion joint is corrugated.
Further, described expansion joint with between housing for welding.
Further, described expansion joint utilizes metallic material to make.
Advantageous Effects of the present utility model is:
(1) the utility model owing to being provided with expansion joint on the housing of boiler, when heating pipe heating produces deformation, due to the telescopic action of expansion joint, reduces the pulling force that heating pipe deformation produces housing, can extend the working life of steam boiler;
(2) the utility model is provided with ear block due to the two ends, left and right at expansion joint, and be bolted two ear blocks, the phenomenon making because internal pressure is much expansion joint excessive tensile reset can be prevented, avoid weld between housing and heating pipe to leak because pulling force produces.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of A-A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-2, a kind of low-pressure tube type waste heat steam boiler with expansion joint, comprise housing 1 and the heating pipe 7 being located at housing 1 inside, housing 1 is provided with retractable expansion joint 2, the effect of expansion joint reduces the pulling force between housing and heating pipe, expansion joint about 2 two ends are provided with ear block 3, ear block 3 is provided with bolt hole 4, be connected with bolt 5 between the ear block 3 at expansion joint about 2 two ends, the two ends, left and right of bolt 5 are equipped with nut 6 and distance between the right and left ear block 3 regulates by nut 6.
Wherein, expansion joint 2 is corrugated, and corrugated expansion joint effectively can alleviate the pulling force that heating pipe produces deformation, but when reality uses, expansion joint also can be designed to other shapes.
Wherein, for welding between expansion joint 2 with housing 1, the sealing both effectively ensureing.
Wherein, expansion joint 2 utilizes metallic material to make.
The utility model is when heating, even if heating pipe creates certain deformation (elongation), owing to there is expansion joint, the housing also deformation thereupon of outside, effectively alleviates the pulling force of heating pipe and shell deformation, extend the working life of boiler.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
