1. The pipe connection
At the nominal diameter is equal to or small f 80 mm pipeline
accessories, appropriate USES threaded connections: nominal
diameter larger than 80 mm pipeline accessories, should use flange
connection.
Has galvanized seamless steel pipe should not be connected by
welding, and choose the individual with the flange connection parts
such as valve welding, deal with the damaged by welding galvanized
layer another do anticorrosive processing.
2. The installation of the casing
Through the wall, the roof should be installed casing pipe. Wear
casing wall length should be equal wall thickness, across the floor
of the sleeve length should be higher than the ground 50 mm. The
space between the pipe and casing should adopt flexible
non-combustible material tamping compaction.
3. Special installation
IG541 fire extinguishing system, carbon dioxide extinguishing
system pipeline, halon 1301 fire extinguishing system of tee joint
shunt export shall be as shown in figure 3-20 horizontal
installation, and should not be installed as shown in figure 3-21.
4. The installation of monitoring components
Each protective zone should be set on the main pressure signal or
traffic signal, to send a signal that cast fire extinguishing
agent. Annunciator shall be located in choose the bottom valve.
5. The pipe fixed
Piping system must be fixation, can withstand the extinguishing
agent produced by the jet thrust and temperature change caused by
the expansion and contraction, withstand the mechanical, chemical,
vibration damage or other effects.
(1) pipe support and hanger biggest space may refer to table 3-14.
Table 3-14 pipe support and hanger largest spacing
(2) the end of the pipe nozzles shall adopt "bracket, bracket and
sprinkler pipe length should not be greater than 500 mm.
(3) the nominal diameter greater than or equal to 50 mm ZhuGanGuan
channel, the vertical direction and horizontal direction at least
each shall be equipped with an anti sway bracket, through each
layer should be set when a multistory buildings sway bracket. Level
through long should add anti sway bracket,
(2) pipe purging, test and paint
Have a network of seven fluorin propane gas fire extinguishing
agent pipeline purging, test and apply reading should meet the
following requirements.
(1) fire extinguishing agent pipeline after the installation,
should carry on the water pressure strength test and pressure leak
test.
(2) water pressure strength test pressure meet the following
requirements.
(1) 1211 halon fire extinguishing system's way of hydrostatic
strength testing pressure measured by type (3-1).
(3) high pressure carbon dioxide extinguishing system pipeline
hydraulic pressure strength test pressure of 15 mpa.
(3) the protection zone is unfavorable to the water pressure
strength test, pressure strength test can be used instead. Air
pressure strength test pressure shall be the water pressure
strength test of 0.6 times. Effective security measures must be
taken when testing.
(4) during pipeline strength test, the pressure to test pressure,
pressure maintenance 5 min, check each joint of the pipe should be
no obvious drip, visual pipe should be no deformation.
(5) air or nitrogen gas pipeline pressure leak test can be used as
the pressure medium,
Two-thirds of test pressure for water pressure strength test. After
the test will be pressure to test pressure, shut off the test
5, safety relief valve
Safety relief valve is used to prevent the system from
overpressure.
6, the selector valve
When there is a network of seven fluorin propane fire extinguishing
system to protect multiple partitions, the selector valve used to
control the fire extinguishing agent into the corresponding
reserves. According to the size of the calculating pipe diameter,
choose the choice of appropriate diameter valve.
7, signal pressure
Pressure signal, signal feedback agent application.
8, nozzle PLPT
Used for discharge agent.
9, high pressure pipe
High pressure pipeline used to transport agent.
10, high pressure pipe fittings
High pressure pipe fittings used to connect to high pressure
pipeline.

Of seven fluorin propane fire extinguishing equipment (bottles of
the group of seven fluorin propane fire extinguishing system)
consists of seven fluorin propane cylinders, container valve,
nitrogen cylinder group, electromagnetic drive, selecting valve,
check valve, header pipe, connecting pipe, pressure indicator,
nozzles and other parts. Need to set up a dedicated between
cylinders.
Have a network of seven fluorin propane fire extinguishing system
of gas fire extinguishing agent storage bottles in between special
cylinders at ordinary times, through the network connection, when
the fire broke out, the extinguishing agent from the cylinder, to
need fire protection zone, through the nozzle discharge fires. Of
seven fluorin propane fire extinguishing equipment (seven fluorin
propane fire extinguishing system), the container valve consists of
seven fluorin propane cylinders, nitrogen drive bottle group,
electromagnetic drive, selecting valve, check valve, header pipe,
connecting pipe and safety relief valve, pressure indicator,
nozzle, high pressure pipes, high pressure pipe fittings and other
parts. Of seven fluorin propane fire extinguishing equipment (seven
fluorin propane fire extinguishing system) filling of seven fluorin
propane fire extinguishing agent colorless, tasteless, clean,
non-conductive, low toxicity, high efficiency of extinguishing,
polluting the protected objects, especially to the atmospheric
ozone layer without any damage.
Widely used in the protection:
1, computer room, communication room, program-controlled exchange
equipment room
2, laboratory, precise instrument room, spraying workshop and
chemical warehouse
3, oil depot, clean workshop, electronic workshop, etc. Various
kinds of high-grade equipment room
4, archives, libraries, museums, instrument room, library, cultural
center, bank vault
5, generator room, power plants, substations, power supply room and
other important places
6, substation, transformer room (room), and other various types of
electric room
7, TV broadcasting center, financial institutions, government
agencies, the airport, buildings, wharf, garage and other important
places.
Have a network of seven fluorin propane fire extinguishing device
is also called the networks of seven fluorin propane fire
extinguishing system, gas extinguishing agent storage bottles was
placed in a special between the cylinder inside, through the
network connection, when the fire broke out, the extinguishing
agent from the cylinder, to need fire protection zone, through the
nozzle discharge fires. Have a network of seven fluorin propane
fire extinguishing system is suitable for protection area of the
room with larger area, requires a separate group there is a small
room to place the cylinder, and the cylinder group after installed
is not moving, pipe network pressure is greater than cabinet, long
transmission distance,
1, pipe network system through network discharge, nozzle evenly, so
the uniform discharge, extinguishing effect is good, and no nozzle
directly discharge pipe network are generally enclosure, discharge
point is so a bit, discharge is not uniform;
2, a pipeline needs to be set separately between the cylinder and
set up the network, without network don't need to, if only to
protect a area, from the economic Angle has a high cost of pipe
network system.
3, if more than one area, there are more than pipe network system
can use the same set of system protection protection zone.
Different fire protection area, specific discharge, without network
need to be set separately for each protection zone cylinder and
fire extinguishing agent, this time without the price of the pipe
network is higher.
Gas fire extinguishing system in periodic inspection, need to check
the pressure of storage vessel and quality, in order to check for
leaks pressurized gas and fire extinguishing agent. Stress can be
through the pressure gauge inspection, quality need to check by
weighing. Therefore, in order to facilitate inspection, each
storage containers should have weighing detection device, as shown
in figure 3-23, when the fire extinguishing agent deep discharge
amount more than the rating (- 5%), automatic alarm.
