Abstract
The utility model relates to the technical field of boiler pipe penetration, in particular to a boiler furnace top pipe penetration rainproof structure which can effectively ensure that a pipe penetration position cannot leak rain and ensure the safe operation of a boiler.
Description
Technical Field
The utility model relates to the technical field of boiler pipe penetrating, in particular to a rainproof structure for a pipe penetrating at the top of a boiler.
Background
The general volume of a boiler is large, a lot of pipelines are arranged on the boiler, some pipelines on the top of the boiler can penetrate through a roof, and as the pipe penetrating through the top of the boiler has the characteristics of large pipe diameter, large thermal displacement and the like, the rain-proof measures for the pipe penetrating through the top of the boiler are often not good, so that rain leakage on the top of the boiler can be caused in rainy days after the boiler is put into operation, finally, water leakage on a steam covering layer and corrosion of equipment in an area can be caused, and the safe operation of the boiler and the tidiness and attractiveness of the whole boiler are influenced.
Disclosure of Invention
In order to solve the problem that rain leakage is easy to occur at the pipe penetrating position of the boiler top, the utility model provides a rain-proof structure for the pipe penetrating position of the boiler top, which can effectively ensure that the rain leakage phenomenon does not occur at the pipe penetrating position and ensure the safe operation of a boiler.
The technical scheme is as follows: the utility model provides a rain-proof structure of boiler furnace roof poling, its includes the boiler roof and runs through the boiler roof wear the top pipeline, its characterized in that, set up the through-hole that the internal diameter size is greater than the external diameter of pipe of wearing to push on the boiler roof, the welding of through-hole department has the sleeve pipe that the upper end is higher than boiler roof upper surface, it passes to wear the pipe of pushing on the pipe the sleeve pipe and external fixation have the internal diameter to be greater than the rain-proof cover of sleeve pipe external diameter, rain-proof cover is located there is the overlap area in the direction of height between sleeve pipe top and the two.
The rainproof cover is further characterized in that the upper surface of the rainproof cover is an outward inclined plane;
the rainproof cover comprises a lower ring sleeve and an upper ring cover plate, the upper ring cover plate is positioned above the sleeve, the lower ring sleeve is positioned outside the sleeve, and a gap is reserved between the lower ring sleeve and the sleeve;
the rain-proof cover is formed by splicing two halves.
After the utility model is adopted, the through hole and the sleeve are larger than the top penetrating pipeline, the top penetrating pipeline can smoothly penetrate without influencing free expansion, the top penetrating pipeline is fixed with the rain cover with the inner diameter larger than the outer diameter of the sleeve, and the rain cover and the top penetrating pipeline are overlapped in the height direction, so that falling rainwater cannot enter the sleeve, and further cannot leak to a boiler steam blanket, and the safe operation of a boiler is ensured.
Drawings
FIG. 1 is a schematic view of the structure of the present invention;
fig. 2 is a top view of the rain cover.
Detailed Description
See fig. 1, fig. 2 shows, a boiler furnace roof poling rainproof structure, it includes boiler roof 1 and the top pipeline 2 that wears that runs through boiler roof 1, set up the through-hole that internal diameter size is greater than the top pipeline 2 external diameters of wearing on the boiler roof 1, the welding of through-hole department has sleeve pipe 3 that the upper end is higher than boiler roof upper surface, in order to guarantee connection stability, adopt full welding, it passes sleeve pipe 3 and external fixation to wear top pipeline 2 has the internal diameter to be greater than the rain-proof cover 4 of sleeve pipe 3 external diameters, rain-proof cover 4 is located and has the overlap region on the direction of height between sleeve pipe 3 top and the two, the overlap region is greater than the hot displacement of wearing top pipeline 2 vertical side, do not throw off when guaranteeing the hot state.
The upper surface of the rain cover 4 is an outward inclined plane, so that rainwater can fall smoothly, and the rainwater is prevented from being accumulated.
The rain cover 4 comprises a lower ring sleeve 4-1 and an upper ring cover plate 4-2, the upper ring cover plate 4-2 is positioned above the sleeve 3, and the lower ring sleeve 4-1 is positioned outside the sleeve 3 and has a gap with the sleeve 3; in order to facilitate installation, the rain cover 4 is formed by splicing two halves.
The structure of this application can let wear top pipeline 2 freely inflation on each space direction, and the rainwater can not get into inside the vapor envelope layer through the roof seepage.
Claims (4)
1. The utility model provides a rain-proof structure of boiler furnace roof poling, its includes the boiler roof and runs through the boiler roof wear the top pipeline, its characterized in that, set up the through-hole that the internal diameter size is greater than the external diameter of pipe of wearing to push on the boiler roof, the welding of through-hole department has the sleeve pipe that the upper end is higher than boiler roof upper surface, it passes to wear the pipe of pushing on the pipe the sleeve pipe and external fixation have the internal diameter to be greater than the rain-proof cover of sleeve pipe external diameter, rain-proof cover is located there is the overlap area in the direction of height between sleeve pipe top and the two.
