Foam Bladder Tanks And Accessories Of Foam Proportioning System For Fire Extinguishing
INTRODUCTION
The Bladder Tank is an integral component of the bladder tank proportioning system, which requires no external power other than adequate water supply. A bladder tank, with an appropriate proportioner(s), injects foam concentrate into the water supply of a fire protection system and automatically proportions over a wide range of flows and pressures.
The National Foam bladder tank is a steel pressure vessel fitted with an internal bladder that stores foam concentrate. During operation, water supplied to the bladder tank displaces the foam concentrate and collapses the bladder until the concentrate is depleted. The bladder tank discharges foam concentrate at approximately the same pressure as the water supplied at the water inlet connection to the tank. Since the bladder tank is pressurized, the bladder should not be refilled during operation.
The foam tank and the low/medium expansion foam generator construct the low/medium foam spraying system. It can also construct the high expansion total flooding extinguishing system with a high expansion foam generator. It is especially suitable to put out the fire caused by an inflammable liquid tank or large scale of spill fire. This method allows the water/foam ratio to remain stable by automatically adjusting to the variable flow rates and pressure conditions that may occur during system operation. It aims at the fire of class A and class B, especially for the fire of class B. The foam bladder tank mainly applied in occasions such as places where the inflammable liquid was produced, stored and transported. This feature makes bladder tanks particularly suitable for multiple hazard systems, sprinkler systems and any other system operating under variable, nonpredictable, flow and pressure conditions. The foam bladder tank is the main unit of the foam extinguishing system. The device consists of a pressure tank, bladder, proportioner, pressure gauge, valves, and pipeline. A pump is needed to supply pressurized water. When pressurized water flows through proportioner, a small part of water (3%-6%) flow into tank from branch pipe to press the bladder to swap out equal foam concentrate and then mix with another part of water (97%-93%) to form foam solution in proportioner and provide to foam generator.

Advantages
1. Pre-piped option for easy installation
2. Reversible water inlet direction: Water can be directed from either of the sides
3. Standard Unit comes with pressure gauges, control valve, thermal pressure relief valve, sight glass and fills & drain valves
4. All valve and accessories accompanied with identification nameplates
5. Can be offered in flanged or grooved inlet/outlet connection
6. Frequently used in aircraft hangars, loading racks, sprinkler systems, and offshore platforms.
INSTALLATION
1. The device should be installed at places with the shelter to avoid sun and rain. Ambient temperature should be within 40°C and leave enough space for operation. The device should be installed at the concrete floor and fastened with anchor nuts.
2. Do the hydraulic test after installing it. Open the tank vent valve first then fill water into the bladder from concentrate draining pipe. Then close the tank vent valve when the bladder is full of water. Pressurize the system and keeping for 10 minutes when the pressure gets test pressure, tank should have no leakage. Close water inlet valve and open water drainage valve and concentrate drainage valve to drain water away in tank and bladder. (We will do this test when products leave the factory)
