(5) specific embodiment

See Fig. 3, Fig. 4, spray piping of the present invention comprises main line 1, main road 2, fire hose 3, is fixed on pipe fitting 8, spray head 10 on the keel 9, main line 1 and main road 2 are positioned at the roof truss floor 14 of plenum chamber more than 13, fire hose 3 is by short tube 12, elbow 5 connected component pipelines 7, short tube 12 passes plenum chamber top board 11, and bye-pass 7 other ends are connected with spray head 10 on being fixed on keel and communicate.The prefabricated outer silk of fire hose 3 one ends is connected with threeway 4 on the main road 2, and the prefabricated internal thread articulation of fire hose 3 other ends is communicated with elbow 5, fire hose 3 employing SUS304 stainless steels making, and inside is corrugated stainless steel tubing; During pipe fitting is installed and connected, adopt the encapsulant of anaerobic adhesive as pipeline, 6 is C shaped steel among Fig. 3,4, and 15 is support among Fig. 4, and 16 is steel roof truss, and 17 is clean zone.

The installation method of spray piping of the present invention, realize by following concrete steps:

Main line installation in place in a, the roof truss layer more than plenum chamber: be included in main line 1 unwrapping wire location in the roof truss layer 14 of plenum chamber more than 13, install, get final product according to conventional standard construction, promptly earlier that pipeline is in place according to the position of unwrapping wire in advance, then according to being successively placed on the support by the order of bassoon to tubule, again according to by bassoon to the order of tubule connection fittings successively; Pipeline generally adopts the connected mode of clip, flange, screw thread; Seepage can appear in pipeline unavoidable seam crossing in installation process, and maintenance must be provided with flange or articulation at the pipe branch place, so that can dismantle repairing for convenience; In addition, selecting for use of encapsulant is even more important, fire protection pipeline system design temperature height, sealing must be tight, the cleanliness factor requirement is arranged in the workshop, toilet, and generally be the preact system, dry at ordinary times in the pipe, therefore the seal for pipe joints material must guarantee all can not leak gas with having under the regimen condition dry, infiltration, and can not produce dirt, so encapsulant can not adopt conventional flax silk to add the form (the hemp silk can shrink, and reduces sealing property, has dust simultaneously and produces) of white paste paint under drying condition, can not adopt polytetrafluoroethylraw raw material band (raw material band is difficult to guarantee the sealing under the pressure more than the 1.0MPa), can only adopt other materials to replace,, have good toughness as anaerobic adhesive, the intensity height, do not produce advantages such as dirt.

Main road installation in place in b, the roof truss floor more than plenum chamber, identical with main line mounting means in place, other are according to standard construction.

The installation of c, fire hose: the prefabricated outer silk of fire hose 3 one ends is communicated with threeway 4 on the main road 2, and the prefabricated internal thread articulation of fire hose 3 other ends is communicated with elbow 5; Fire hose 3 adopts the SUS304 stainless steel to make and inside is corrugated stainless steel tubing, be since Fire Control System Design pressure all than higher, for guaranteeing that pipe-line system can not be corroded, wear out, can bring into play its normal fire-extinguishing function concurrently for a long time, it mainly acts on the fire hose here and be: (1) is used for adjusting the error that exists in the actual installation between the elbow of wearing plenum chamber top board place arm and the flexible pipe; (2) reduce the displacement that pipeline is produced because of hydraulic blow or mechanical collision; (3) can make the standpipe of wearing top board can be because of the person in charge does not rock, the sealing of perforate part can not destroyed yet, and sealing effectiveness is very good, thereby the cleanliness factor of toilet is not had any influence.

D, bye-pass installation in place: bye-pass 7 is communicated with fire hose 3 by short tube 12, elbow 5, wherein short tube 12 passes plenum chamber top board 11, because pipeline is in light weight, support 15 can be directly installed on the plenum chamber ceiling board, this section of tubing is installed and is carried out in the zone, toilet, must strictly observe the construction requirement of toilet during installation, enter all material and the necessary scrub of facility of toilet, must not in the toilet, carry out pipeline cutting, polishing operation.When standpipe is worn the top board perforate, must be equipped with the special-purpose dust catcher in toilet, the pollutant that produces during with perforate is removed, and standpipe should adopt trim or other similar materials and fluid sealant that hole is sealed after wearing the top board installation immediately, in order to avoid dust granules enters the toilet.

E, the connector that is fixed on the keel are installed: FFU keel 9 are connected with bye-pass 7 by keel connector 8, and the connector on the keel must strictly observe the construction requirement of toilet when installing, note finished product protection, does not destroy the FFU keel.

F, zone duct air pressure and the water pressure test: after all mains on trunk line, arm etc. install, errorlessly on inspection get final product pressure testing, pressure test pressure carries out according to design and code requirement; Damage process equipment or other professional finished products when avoiding pressure test because of leaking, should advanced promoting the circulation of qi press test, carry out the water pressure test again, operating personnel, inspection personnel must operate in strict accordance with the specific requirement of toilet's construction, guarantee the clean environment of factory building.

The g spray head is installed: spray head 10 is fixed on the keel 9 and is communicated with bye-pass 7, clean herein regional 17 internal cause FFU spine arrangement rates are than higher, even the part is abound with FFU, and the room standard width of a room in an old-style house is bigger, consider the attractive in appearance of room entire arrangement, spray head 10 can only be fixed on the crosspoint of FFU keel; Loine pressure test and wash and spray head 10 could be installed after qualified in addition will be noted the branch of " going up spray " and " spray down " during installation, adorn mistake, and will adopt the installation of spray head special spanner, otherwise can damage spray head 10.
