Abstract
The utility model relates to a water supply and drainage device for a buried pipeline. The water supply and drainage device comprises a butterfly valve hand wheel, a connecting rod, a butterfly valve, a draw-off valve and a water tube, wherein one end of the water tube is arranged on the ground; the other end of the water tube is arranged below a ground frozen earth layer; the butterfly valve and the drain-off valve are arranged on the water tube at the end below the ground frozen earth layer; a grait pit is formed at each of the bottom of the butterfly valve and the bottom of the drain-off valve; and the butterfly valve is connected with the butterfly valve hand wheel on the ground by the connecting rod. Compared with the prior art, the water supply and drainage device for the buried pipeline has the beneficial effects as follows: the water supply and drainage device has the characteristics of being low in cost, simple in structure, reasonable in design and convenient to use, so that a removing problem for residual water or foam liquid in the pipeline after a pipeline system hydrostatic test or a fire extinguishing system implements fire extinguishment is effectively solved, and therefore, the corrosion of the residues to the pipeline is reduced, the service life of the pipeline is prolonged, the fire extinguishing system is safer and more reliable and the working efficiency of fire extinguishment is improved.
Description
Technical field
The utility model relates to tube equipment field, particularly a kind of buried pipeline water feeding and draining device.
Background technique
in the low-expansion foam Fire Control System Design, due to Placement of general layout restriction and technique needs, fire pump station and need to implement between the protective area of fire extinguishing general distance all far away, often have the part fire protection pipeline and need buried-pipe laying, the pipeline buried-pipe laying, just formed the low spot of pipe-line system, after the pipe-line system hydrostatic test or fire-fighting system are implemented fire extinguishing, water or foam solution residual in pipeline have certain corrosivity to pipeline, reduced the working life of pipeline, hindered the fire extinguishing operation of firefighters, cause personnel's injures and deaths when serious, therefore, the queueing problem of residue, just become problem demanding prompt solution.
Summary of the invention
The purpose of this utility model is to provide a kind of eliminating and remains in ducted water or foam solution, extends the pipeline buried pipeline water feeding and draining device in working life.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of buried pipeline water feeding and draining device, comprise butterfly valve handwheel, connecting rod, butterfly valve, drain valve and water pipe, described water pipe one end is arranged on ground, the water pipe the other end is arranged at below the frozen soil layer of ground, the water pipe of this end is provided with butterfly valve and drain valve, be provided with cobble bottom butterfly valve and drain valve and cheat, butterfly valve is connected with ground butterfly valve handwheel by connecting rod.
Compared with prior art, the beneficial effects of the utility model are:
A kind of buried pipeline water feeding and draining device, have cost characteristics low, simple in structure, reasonable in design, easy to use, after effectively having solved the pipe-line system hydrostatic test or fire-fighting system enforcement fire extinguishing, residual water or the queueing problem of foam solution in pipeline, thereby reduced the corrosion of residue to pipeline, extend the working life of pipeline, made fire-fighting system more safe and reliable, improved the working efficiency of fire-fighting.
Description of drawings
Fig. 1 is structural drawing of the present utility model.
6-water pipe, 7-ground, 1-butterfly valve handwheel, 2-connecting rod, 3-butterfly valve, 4-drain valve, 5-cobble hole
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of buried pipeline water feeding and draining device of the utility model, comprise butterfly valve handwheel 1, connecting rod 2, butterfly valve 3, drain valve 4 and water pipe 6, water pipe 6 one ends are arranged on ground 7, water pipe 6 the other ends are arranged at below 7 frozen soil layers of ground, the water pipe 6 of this end is provided with butterfly valve 3 and drain valve 4, and butterfly valve 3 and drain valve 4 bottoms are provided with cobble hole 5, and butterfly valve 3 is connected with butterfly valve handwheel 1 on ground 7 by connecting rod 2; This device is applicable to any supply and drain water system.
When using the utility model, when needs used low-expansion foam or water lines, rotation butterfly valve handwheel 1 was opened butterfly valve 3 by connecting rod 2, and pressure foam mixed solution or water and water pipe 6 are connected, drain valve 4 autoshutdowns; When the interior residual foam mixing liquid of needs emptying water pipe 6 or ponding, rotation butterfly valve handwheel 1 cuts out butterfly valve 3 by connecting rod 2, and pressure foam mixed solution or water and water pipe 6 disconnect, and drain valve 4 is opened automatically, so just can interior foam mixing liquid or the ponding of emptying water pipe 6.
Above described be only basic principle of the present utility model, be not that the utility model is imposed any restrictions, everyly according to the utility model, it is carried out equivalent variations and modification, all within the category of the art of this patent protection scheme.
