Description
Technical Field
The utility model relates to an overhaul structure that is used for large-scale horizontal high temperature heater hydroecium.
Background
At present, horizontal high-temperature heaters of boilers are increasingly large in size, the diameter of a water feeding opening of a water chamber end socket of the horizontal high-temperature heaters is also increasingly large, so that a worker easily steps on the water feeding pipe when entering the water feeding pipe during maintenance, or tools fall into the water feeding pipe, safety and accident potential exist, and the horizontal high-temperature heaters are inconvenient to maintain.
Disclosure of Invention
The utility model aims at the above-mentioned not enough of prior art, provide a large-scale horizontal high temperature heater hydroecium overhauls structure, it can cover the water-feeding mouth of hydroecium head, can avoid the workman to step on empty and the phenomenon that the instrument fell into water supply pipe when overhauing, stop safety and accident hidden danger, convenient to overhaul.
In order to achieve the purpose, the utility model discloses a large-scale horizontal high temperature heater hydroecium overhauls structure, including the hydroecium head that is equipped with water-feeding mouth and maintenance manhole; the method is characterized in that: the water chamber sealing head is characterized by also comprising a flat plate arranged in the water chamber sealing head, wherein the flat plate covers the tail end of the water supply port, the lower side of the flat plate is fixedly connected with an annular check ring, the check ring is positioned in the water supply port, and the upper side of the flat plate is fixedly connected with more than one handle;
during maintenance, the flat plate shields the tail end of the water supply port, the annular retainer ring can prevent the flat plate from sliding, the water supply port is always sealed during maintenance, the phenomena that workers step on the water supply pipe and tools fall into the water supply pipe can be avoided, potential safety hazards and accident hazards are avoided, and the maintenance is convenient;
as a further improvement of the utility model, the flat plate is formed by combining two semicircular plates, the annular retainer ring is formed by combining two semicircular retainer rings, and the upper sides of the two semicircular plates are both fixedly connected with a handle; the combined structure is convenient for passing through an inspection manhole due to the fact that the combined structure corresponds to a flat plate with a larger size;
to sum up, the utility model discloses can cover the water-feeding mouth of hydroecium head, can avoid the workman to step on empty and the instrument falls into water supply pipe's phenomenon when overhauing, stop safety and accident hidden danger, convenient to overhaul.
Drawings
Fig. 1 is a front view of an embodiment of the present invention.
Fig. 2 is a view taken along direction a of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the water chamber maintenance structure of the large horizontal high-temperature heater in the embodiment includes a water chamber end enclosure 1 provided with a water supply port 2 and a maintenance manhole 3, and a flat plate 4 arranged in the water chamber end enclosure 1, wherein the flat plate 4 is formed by combining two semicircular plates 4, the flat plate 4 shields the end of the water supply port 2, the upper sides of the two semicircular plates 5 are fixedly connected with a handle 6, the two handles 6 are symmetrically arranged, the lower sides of the two semicircular plates 5 are fixedly connected with semicircular retaining rings 7, the two semicircular retaining rings 7 form an annular retaining ring, and the annular retaining ring is located in the water supply port 2;
during maintenance, the flat plate 4 shields the tail end of the water supply port 2, the annular retainer ring can prevent the flat plate 4 from sliding, the water supply port is always sealed during maintenance, the phenomena that workers step on the water supply pipe and tools fall into the water supply pipe can be avoided, potential safety hazards and accident hazards are avoided, and the maintenance is convenient; the modular construction facilitates the passage of the manhole 3, corresponding to the plates 4 of greater dimensions.
