Abstract
An underground fire hydrant protecting cylinder mainly resolves the problems that the prior fire hydrant protecting cylinder with short service life is not convenient to install and maintain, and the branch pipeline is easy to be damaged, which is characterized in the cylinder body (1) is fixed on the water pipeline (3) which is arranged on the lower portion of the cylinder body (1) and is connected with the supporting pipe (4) which is sleeved outside the branch pipeline (2) through a screw. The upper end of the supporting pipe (4) is connected with the fire hydrant (5), and the cylinder body (1) is provided therein with the water discharging pipe (7) which passes through the side wall of the cylinder body and is connected with the valve (6) above the ground surface. The lower end of the water discharging pipe (7) is close to the bottom of the cylinder body (1) and the space between the supporting pipe (4) and the cylinder body (1) is sealed. The underground fire hydrant protecting cylinder has the characteristics that the protecting cylinder is convenient to install and maintain, and the branch pipeline is corrosion-resistant and not easy to be damaged.
Description
Technical field:
The utility model relates to the used underground firebreak device in fire safety field, especially underground hydrant protection tube.
Background technology:
In the fire safety field, the common employing is installed in the interior fire plug fire preventing generation of valve pit, and the most frequently used underground hydrant is mounted in the interior cylindrical tube of valve pit at present, and cover is arranged on the cylindrical shell, and an overfall is arranged on the tube wall of fire plug bottom; After the fire plug pressure testing or using, the water of fire plug internal memory will flow out by overfall and enter cylindrical shell, avoid corrosion to the fire plug inwall, because the water that overfall flows out remains in the cylindrical shell, along with increasing of pressure testing number of times, the water that accumulates in the cylindrical shell can get more and more, make troubles to staff's maintenance, the corrosion resistant coating of cylinder inboard wall and water under high pressure fire-fighting water main outer wall will come off through long-time immersion, cause the corrosion of ponding, thereby influence the application life of this fire services installations cylinder inboard wall and high pressure fire fighting water main outer wall; When cylindrical shell is installed, cylindrical shell is fixed on the bracing frame of Trunk Line top, the branch pipeline that communicates with the person in charge passes on the fire plug that is associated at the bottom of the cylindrical shell in the cylindrical shell, when groundwater level is high, water can cause the damage of branch pipeline to the buoyancy of cylindrical shell, need the constructor to enter the cylindrical shell bottom in the cylindrical shell side when cylindrical shell is installed, it is inconvenient that it is installed.
The utility model content:
In order to overcome existing fire plug casing installation and maintenance inconvenience, to divide the deficiency that pipeline is fragile and application life is short; the utility model provides a kind of underground hydrant protection tube, this underground hydrant protection tube have installation, maintenance convenient, divide pipeline to be difficult for damaging and corrosion resistant characteristics.
The technical solution of the utility model is: this underground hydrant protection tube comprises cylindrical shell, divides pipeline and fire plug; fire plug places in the cylindrical shell; on cylindrical shell and the water pipeline that is fixed on the cylindrical shell bottom and be enclosed within the outer stay pipe of branch pipeline and link to each other by screw thread; the stay pipe upper end links to each other with fire plug; cylindrical shell is built-in with and passes the gutter that its sidewall links to each other with ground surface top valve; the gutter lower end seals between stay pipe and the cylindrical shell near the cylindrical shell bottom.
Be equipped with rubber cushion and platen successively on the stay pipe of above-mentioned cylindrical shell bottom interior wall top; Platen is connected with the stay pipe outer wall thread; Stay pipe is welded on the water pipeline.
The utlity model has following beneficial effect: owing to take such scheme, cylindrical shell be fixed on water pipeline upper support pipe and link to each other by screw thread, cylindrical shell when mounted, be welded on the threaded stay pipe of outer wall on the water pipeline earlier, again bottom cylindrical shell with threaded hole is aimed at stay pipe, rotary barrel gets final product, and makes cylindrical shell quick and easy for installation; Stay pipe is enclosed within outside the branch pipeline, and cylindrical shell is subjected to can not damaging the branch pipeline behind the buoyancy force of underground water; Cylindrical shell is built-in with and passes the gutter that its sidewall links to each other with ground surface top valve, the gutter lower end is near the cylindrical shell bottom, after the fire plug pressure testing or using, the water that the fire plug overfall flows out can be extracted out with the water pump on ground by gutter, can be in cylindrical shell ponding, and then can not cause corrosion to cylindrical shell; Seal between stay pipe and the cylindrical shell, when underground water level was high, underground water can not enter in the cylindrical shell; Have the installation, maintenance convenience, divide pipeline to be difficult for damaging and corrosion resistant characteristics.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-cylindrical shell among the figure, 2-divides pipeline, 3-water pipeline, 4-stay pipe, 5-fire plug, 6-valve, 7-gutter, 8-rubber cushion, 9-platen, 10-flange, 11-overfall.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this underground hydrant protection tube comprises cylindrical shell 1, divides pipeline 2 and fire plug 5, and fire plug 5 places in the cylindrical shell 1, and stay pipe 4 is welded on the water pipeline 3 and is enclosed within outside the branch pipeline 2, and cylindrical shell 1 is subjected to can not damaging branch pipeline 2 behind the buoyancy force of underground water; Cylindrical shell 1 and stay pipe 4 link to each other by screw thread, and cylindrical shell 1 is welded on the threaded stay pipe 4 of outer wall earlier on the water pipeline 3 when mounted, again bottom cylindrical shell 1 with threaded hole is aimed at stay pipe 4, and rotary barrel 1 gets final product, and makes cylindrical shell 1 quick and easy for installation; Stay pipe 4 upper ends link to each other by flange 10 with fire plug 5, cylindrical shell 1 is built-in with and passes the gutter 7 that its sidewall links to each other with ground surface top valve 6, when fire plug 5 pressure testings or use, the water that fire plug 5 overfalls 11 flow out can be extracted out by the water pump on gutter 7 usefulness ground, can be in cylindrical shell 1 ponding, and then can not cause corrosion to cylindrical shell 1 inwall; The ponding in the cylindrical shell 1 is convenient to pump near cylindrical shell 1 bottom in gutter 7 lower ends; Be equipped with rubber cushion 8 and threaded platen 9 successively on the stay pipe 4 of cylindrical shell 1 bottom interior wall top, rotation platen 9 compresses rubber cushion 8, makes sealing between stay pipe 4 and the cylindrical shell 1.
