Description

The installation method of fire-fighting pipe fitting
[technical field]
The present invention relates to fire-fighting equipment, particularly relate to a kind of installation method of fire-fighting pipe fitting.
[background technique]
According to fire-fighting requirements, the fire-protection equipments such as the wall hydrant of fire extinguishing all must be installed in building.Wall hydrant is the band valvular interface of pipe network in house to delivery of water, and as the indoor fixed fire protection system of building etc., it is arranged in fire hydrant box usually, supports the use with fire-extinguisher water hose and the equipment such as hydraulic giant and fire hose reel.Water supply line in building is divided into independently domestic water line and fire protection pipeline, wherein, fire protection pipeline comprises the pipeline connecting spray equipment in the pipeline of wall hydrant and junction chamber, wall hydrant is connected, for wall hydrant and spray equipment provide water source with indoor fire protection pipeline respectively by parts such as tee unions with indoor spray equipment.Fire protection pipeline is formed by connecting by fire-fighting pipe fitting.Traditional fire-fighting pipe fitting forms fire protection pipeline by welding or thread connecting mode, and the Placement of this pipeline makes maintenance particularly inconvenience, and there is time-consuming, effort, long construction period, the defects such as cost is high, and installation efficiency is low.
[summary of the invention]
The present invention is intended to solve the problem, and provides a kind of processing and quick and easy for installation, and for ease of maintenaince, installation efficiency is high, the installation method of the fire-fighting pipe fitting that cost is low.
For achieving the above object, the invention provides a kind of installation method of fire-fighting pipe fitting, the method comprises:
A, intercept the identical steel pipe of some joint diameters by design length at the construction field (site);
B, on the intercepted outer peripheral surface often saving steel pipe two ends proximal end face, process one around the annular slot of the indent of circumferential surface;
C, process the outer surface rust prevention by applying liquid material paint often saving steel pipe of draw-in groove, then spray paint, form the more piece fire hose reel meeting design length;
D, the multiple clip connected of described more piece fire hose reel is become indoor fire-fighting pipeline, the connection part of fire hose reel and clip is sealed by Sealing.
In step a, described steel pipe is Coating Steel Pipe.
In step b, described annular slot is U-groove bevel.
In steps d, described clip is when connecting every two joint fire hose reel, and it saves the annular slot phase clamping of fire hose reel respectively with two, and fastening by fastening piece.
In steps d, described Sealing is contained in the connecting part of two joint fire hose reels in clip.
Contribution of the present invention is, it is low that it efficiently solves traditional fire-fighting pipe fitting installation efficiency, the problems such as inconvenient maintenance.The present invention by processing draw-in groove on fire hose reel, and realizes the connection of fire-fighting pipe fitting by fastener.During installation, as long as be stuck in by fastener in the groove of two fire hose reels, and can complete installation with fastening piece is fastening, installation process is convenient and swift.During maintenance, as long as unclamp fastener, can keep in repair, therefore greatly can improve installation and maintenance efficiency.

Fig. 1 is fire hose reel in method of the present invention and clip connected schematic perspective view.
Fig. 2 is fire hose reel in method of the present invention and clip connected sectional view.
[embodiment]
The following example is further explanation of the present invention, does not constitute any limitation the present invention.
The installation method of fire-fighting pipe fitting of the present invention processes and install fire-fighting pipe fitting at the construction field (site), to form the method for the fire protection pipeline in building.
In the present embodiment, intercept the identical Coating Steel Pipe of some joint diameters by design length cutting machine at the construction field (site).Intercepted steel pipe being processed one around the annular slot 11 of the indent of circumferential surface by the common process such as car, milling on the outer peripheral surface often saving steel pipe two ends proximal end face, the U-shaped profile of this annular slot 11, embedding wherein for making the connecting end of clip.Processing the outer surface rust prevention by applying liquid material paint often saving steel pipe of draw-in groove, then spray paint, in case Coating Steel Pipe corrosion and oxidation.By above-mentioned steps, namely define the fire hose reel 10 that can be used for installing as shown in Figure 1.
As shown in Figure 1 and Figure 2, after fire hose reel machines, the multiple clip 20 of described more piece fire hose reel 10 is connected into indoor fire-fighting pipeline, and the connection part of fire hose reel and clip is sealed by seal ring 30.
Described clip is general pipe connection card, and as shown in Figure 1 and Figure 2, this clip 20 is clips of the ring bodies matched with fire hose reel 10 caliber, the adaptive different-diameter of fire hose reel 10 of different size.In Fig. 1, described clip 20 is symmetrical by two, and semicircular half clip 21,22 that shape is identical is formed, and when connection two fire hose reels 10, the two and half involutory connections of clip 21,22 are also fastening, form circular clip 20.More specifically, in Fig. 1, be provided with circumferential rectangle or trapezoidal seal groove 211,221, for arranging seal ring 30 in the inwall central authorities of two and half described clips 21,22.L shape flange 212,222 is provided with, for engaging with the annular slot 11 of fire hose reel in the connecting end both sides of the edge of half clip 21,22.Symmetry is provided with and the ear seat 213,223 of the band screw of evagination, for being fastenedly connected by two and half clips, 21,22 and two fire hose reels 10 at the connecting end outward edge of half clip 21,22.
During installation, first seal ring 30 is overlapped the end of a fire hose reel 10 wherein, there is the fire hose reel of seal ring involutory with cover another root fire hose reel 10 again, then two and half clips 21,22 are enclosed within the connecting part of two fire hose reels 10 and involutory, two and half clips 21,22 involutory time seal ring 30 is embedded in the seal groove 211 of two and half clips, the connecting part of two fire hose reels 10 is sealed.Meanwhile, the L shape flange 212,222 of two and half clips snaps in the annular slot 11 of two fire hose reels respectively, tightens fixing respectively, namely complete the connection between two fire hose reels 10 with bolt through the screw of ear seat 213,223 by two and half clips 21,22.Many fire hose reels can use the same method and connect successively, form special fire protection pipeline after connecting.
When carrying out fire protection pipeline maintenance, only unclamp clamping bolt, take off clip 20, can keep in repair or change fire hose reel.
By this, method of the present invention can carry out processing and the installation of fire hose reel at the construction field (site), and installation process is convenient and swift, can greatly improve fire hose reel installation efficiency, and is convenient to maintenance.
Although by above embodiment to invention has been announcement, protection scope of the present invention is not limited thereto, under the condition not departing from the present invention's design, all will fall in right of the present invention the distortion, replacement etc. that above each component does.
