Deluge valve
- Product description: deluge valve
Product introduction
The pressure inside the cavity diaphragm chamber (control), installed in the protected area of the detection system to control, the detection system are the same that the deluge valve diaphragm drive system, this system can be divided into electric control, pneumatic or hydraulic control.
Deluge alarm system in the system are open nozzle on the side of the pipe network and by the deluge valve water supply.

1. The deluge valve diaphragm
2. Leverage deluge valve
Fourth, the deluge valve two performance characteristics
1, the system open nozzle are fitted on the side of the pipe network, once opened the deluge valve, the reserve the nozzle spray water at the same time, it can spread quickly extinguished, burning fierce is flammable explosive place of fire.
2, open the deluge valve with different control detection systems, which constitute a wet type control system, the dry type control system or electric control system.They both control deluge valve diaphragm chamber the pressure inside the cavity (control), and can control the deluge valve open and close.
Deluge valve can also be combined into foam and foam systems deluge system, some explosive burning dangerous liquid used for fighting fires.
On the line configuration are equipped with emergency manual ball valve with a lock as an auxiliary switch.
Installation and user information
A, install
1, the deluge alarm valve, generally for the vertical installation, also can be installed horizontally, should be in order to my company to ask for installation in advance.No matter what kind of installation, the sides of the deluge alarm valve should have enough space.
2, hydraulic alarm installation method should be out "small mouth and big", "galvanized pipe outlet pipe is 1, the outlet of the alarm bell to alarm the highs of the drainage pipe, separate received without pressure drain.As much as possible so as to draw off the alarm, unimpeded.
3, the control valve outlet should be through the appropriate diameter galvanized pipe connected to the appropriate drain path.
4, rain alarm valve of the import and export signal isolation valve should be installed, and it is recommended to use this company produces the signal butterfly valve.When the maintenance wet alarm valve so more convenient.
5, solenoid valve should be controlled by control module is connected to the ark, when there is a fire, drive the electromagnetic valve, the electrical signals should be kept until the signal to stop the fire to stop.The default for 24 v dc signal, customers can be customized.
Second, the user instructions
1, the user when ordering, please specify the name of the product in order, type, specification, quantity, time of delivery.
2, random deluge valve device with 2 only 2.5 MPa pressure gauge, pressure switch, hydraulic alarm 1 only, electromagnetic valve, operation instruction, one copy each of the certificate of approval, the wafer fire signal butterfly valve or need to separate the order the wafer butterfly valve and other fittings.
3, the deluge valve device should be checking, action once a month, remove the maintenance once a year, flushing pipe, remove scale, material, check all the moving parts, the performance of the seal.If the axis with and without scratch, burr, deformation;Orifice have blocked;Seat without scale dirt, rust;The normal service life of rubber parts for a year and a half, such as creep, the indentation deformation, aging hardening, paste, abrasion and other phenomena, should be replaced immediately.
4, when the deluge valve device components installed, must be raised and lowered in the body in and out of the flange force, it is strictly prohibited in other locations or parts move, so as to avoid undue harm is caused.
5, the deluge valve device in special environment, such as severe corrosion, explosion-proof situations, users need to use the environment situation, the company is according to the actual situation to give a special order.
