Abstract automatic dry pipe sprinkler method commonly flanged, horizontal piping installed the card holder typically the major hanger high water tank must be in place ahead of the cap structure, and the require to do complete water test installation Alarm Valve must be installed initial water control valve, alarm valve, and then once again under directions to assist pipeline equipment and accessories installed: Pump Combined with the installation of the position have to be clearly marked, valve place must be straightforward to operate, combined with nearby devices must not be obstacles.
Crucial words dry pipe alarm valve branch high water tank spray head manifold method components and installation of sprinkler head
Automatic sprinkler method Pipe Typically use galvanized steel and pipe fittings, when the pipe nominal diameter much less than or equal to 100mm, the threaded connections must be used when bigger than 100mm nominal diameter pipe, the use of flanged or welded connections. Welded connections significantly more handy in the construction, but require to be nicely on the weld seam inside and outside surface corrosion, to make certain that the welding approach has been damaged zinc coating a timely manner.
An automatic sprinkler method in the trunk, branch pipe installation1. Spray in the pipe flange connection with the common, the finest of each and every piping length must not exceed 6m, crossing a straight pipe can be connected together to use the inverted chain installation, reasonably straightforward, but when such construction must not be as well lengthy. Soon after the numbers are adjusted by order direct the installation, lifting a single finish of the pipe must be lifted initial, and then lift the other finish to be stable.
2. Fastening flange pipe connection, check flange finish face is clean. By 3 ~ 5mm of rubber pads. Fastening bolts fastening the worst must be initial point, followed by symmetrical fastening. Flange interface, typically installed in very easily removable position.
3. The level of the card holder to install pipelines typically the major hanger, each and every dry pipe commonly essential for a hanger to stop sway. Pipeline adjustments direction, the require for extra assistance against Akira.
4. Standpipe concealed inside the shaft when the tube-wells that require embedded iron, and then install the card at the iron frame fixed, the installation place distance from the ground or floor is commonly 1.5 ~ 1.8m.
5. Branch of the pipeline must be preceded by pre-reserved port in lifting high quality. Then the use of wire hyperlinks positioning reserved port. Opening the dry pipe welding, plus all the reservation I have a high quality temporary plug board, to stop debris falling into.
6. When the pipe reducer, the common use of reducer fittings. Shall not be used in the pipe elbow bushing. When the construction have to be used up, what must the hyperlinks out there on a single, four-way must not significantly more than two.
7. With every single branch along the water pipe, adjacent Sprinklers Set among the hanger pipe must not be much less than 1, when the nozzle 3 can be separated when the distance is much less than L8m paragraph settings, but the hanger spacing must not exceed 3.6m. Every water distribution branch must set up a stand against Akira. Pipe hanger installation place must not stop the spray nozzle effect.
Second, automatic sprinkler consideration to quite a few key installations(A) high water tank installed high water tank must be in place ahead of the cap structure, and the require to do complete water test. Fire water tanks and other water sharing must be to make certain that fire water that has not been used, leaving a ten-minute fire-water. When combined with the living, must be produced normally in a mobile state of water, to stop deterioration in water good quality. Fire mains must be added a single-way valve. All tank nozzles require pre-processing, if the opening scene on the welding tank welding must strengthen the board.
(B) installation of alarm valve alarm valve must be installed to install the water control valve, alarm valve, then according to equipment specifications and then install the auxiliary pipes and accessories. Water control valve, alarm valve and water distribution mains connection, must make water flow in the very same direction. Alarm Valve installation place must meet the design requirements. When the design is not required, the alarm valve must be installed to facilitate operation in a clear position from the interior floor height appropriate for the 1.2m, the distance on both sides of the wall not much less than .5m, the wall from the front and not much less than 1.2m. Installation of alarm valve have to be installed indoor floor drain floor drain.
