Description

Fire protection pipeline structure

Technical field

This utility model relates to fire-fighting domain, particularly to a kind of fire protection pipeline structure.

Background technology

Fire protection pipeline, as a kind of tubing set up for fire-fighting, connects various fire-fighting equipment, equipment, disappears in order to carry Fire extinguishing water, gas or other media, owing to fire protection pipeline remains static throughout the year, therefore to its requirements for pipes relatively Height, at present, existing fire protection pipeline structure is typically with branched network fire water-supply and looping network fire water-supply, this extinguishing pipe Although road structure is easy to use, but it also exists serious deficiency at aspects such as assignment of traffic, breaks down once certain water pipe, Overall safety will be reduced.

Utility model content

The purpose of this utility model is to provide a kind of fire protection pipeline structure, and it has ring-type fire protection pipeline structure, effectively Improving overall workability, pipeline has by good weatherability simultaneously, will not light flimsy advantage.

Above-mentioned technical purpose of the present utility model has the technical scheme that

A kind of fire protection pipeline structure, including water tank, fire-fighting water channel, pipe network, described fire-fighting water channel is respectively arranged at the two ends with two and disappears Waterproof pump, described fire pump is connected in parallel on fire-fighting water channel, and leads to pipe network by pipeline respectively, described pipe network in the form of a ring, and Divide and have some water service pipes to be connected to each fire extinguishing node.Described water tank is positioned at top, and is connected on water service pipe by downpipe.

It is arranged such, by the setting of loop configuration, when can make that any pipeline goes wrong in total Impact all without to entirety, still can lead to ignition point from other pipelines, thus reach the purpose of fire extinguishing, pass through top simultaneously Water tank, utilize gravity to supply water at the initial stage of fire, it is to avoid fire pump spent time when fetching water up is too much, and During fire mid-term, can be supplied water by fire pump, thus reach the purpose of fire extinguishing.

Arrange further: described each pipeline entrance end is equipped with stop valve.

It is arranged such, stop valve is set by each port, go wrong once at certain pipeline, can carry out more in time Change, it is not necessary to whole water supply is cut off, it is only necessary to cut off the stop valve at two.

Arrange further: described fire extinguishing node is several fighting nozzles.

Being arranged such, several fighting nozzles that fire extinguishing node is arranged, for water spray, play the effect of fire extinguishing.

Arrange further: described each pipeline all has extinguishing pipe to make.

Being arranged such, the extinguishing pipe for overall fire-fighting use typically requires has the most special performance, unusable General steel pipe or other pipelines replace.

Arrange further: described extinguishing pipe is successively by anti-corrosion of metal layer, steel pipe, epoxy resin layer, heat-insulation layer and internal layer structure Become.

It is arranged such, makes it have excellent resistance to chemical corrosion by anti-corrosion of metal layer, fundamentally solve same Series products occurs the problems such as surface oxidisation corrosion after long-term use, thus substantially increases the use longevity of fire-fighting dedicated pipe Life.And the setting of epoxy resin layer, owing to the addition of fire proofing in coating material so that the heat resistance of this product and its Its like product is compared and is improved.So not interfering with use, setting of heat-insulation layer when ambient temperature steeply rises around yet Put, for avoiding pipeline to freeze at extremely arctic weather, thus cause pipeline to use, the most now breaking out of fire, after The most hardly imaginable.

Arrange further: described epoxy resin layer thickness is at 350～400 microns.

It is arranged such, by the suitable thickness of epoxy resin layer, material can be saved, integrated piping can be played again important Effect, epoxy resin has good performance simultaneously, and it has good physics, chemical property, and it is to metal and nonmetal The surface of material has the adhesive strength of excellence, and dielectric properties are good, and deformation retract rate is little, product size good stability, hardness Height, pliability is preferable, to alkali and major part solvent-stable

In sum, this utility model has the advantages that the pipe network by loop configuration so that overall use is pacified Quan Xingyou is greatly improved, it is to avoid occurring that a circuit failure causes entirety to use, the extinguishing pipe simultaneously used has The most corrosion-resistant, weatherability, reduces and uses fault rate, and important work is played in the normal work for safety assurance fire-fighting system With.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Embodiment 1: a kind of extinguishing pipe 9 road structure, as it is shown in figure 1, whole extinguishing pipe 9 road is ring network structure, wherein, bag Including water tank 1, fire-fighting water channel 2, pipe network 3, fire-fighting water channel 2 is respectively arranged at the two ends with two fire pumps 4, and the two fire pump 4 is also Connection connects, and leads to pipe network 3 by pipeline, and pipe network 3 is provided with some with waterway, is used for being connected to each fire extinguishing node 6, fire extinguishing Node 6 is made up of several fighting nozzles, and water tank 1 is positioned at top, and is connected on waterway by downpipe 7, every pipeline On all front and back ends be designed with can be used for cutting off the stop valve 8 of pipeline, as in figure 2 it is shown, all there is anti-corrosion of metal layer in whole extinguishing pipe 9 road 10, the extinguishing pipe 9 that steel pipe 11, epoxy resin layer 12, heat-insulation layer 13 and internal layer 14 are constituted is made, the wherein thickness of epoxy resin layer 12 Degree is at 350～400 microns.

Its groundwork mode is as follows, when there is the situation of fire, is first supplied water by high-order water tank 1, passes through In the position at top, by under the effect of gravity, can be transported to put out a fire on node 6 with more suitably pressure and speed by water, but Owing to the water of water tank 1 is limited, therefore can accelerate the speed of water conveying when fire occurs and using, and be now placed in bottom Fire pump 4 proceeds by work, is supplied to endlessly manage by the water in fire-fighting water channel 2 by the work of fire pump 4 In net 3, thus reach the purpose of fire-fighting fire extinguishing.

Embodiment 2: difference from Example 1 is, once in pipe network 3 any pipeline occur damaging, fault or During blocking, all can be transported to specify position by the pipe network 3 of annular, import and export two ends at each pipeline simultaneously and be equipped with cut-out Valve 8, can open stop valve 8, closes the pipeline gone wrong, thus whole system structure still can be continuing with, and keep in repair Pipeline also can be keeped in repair in time by personnel by stop valve 8, it is to avoid needing when maintenance supplies water whole system closes.

Embodiment 3: be with embodiment 1 or embodiment 2 difference, as in figure 2 it is shown, the extinguishing pipe 9 used is by metal Anticorrosive coat 10, steel pipe 11, epoxy resin layer 12, heat-insulation layer 13 and internal layer 14 are constituted successively, and epoxy resin layer 12 thickness is 350 ～400 microns so that whole extinguishing pipe 9 has preferable performance, including anti-corrosive properties, weatherability, mechanical strength etc., it is simple to permanent Use is hardly damaged.

The above embodiments are only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but As long as all being protected by Patent Law in right of the present utility model.
