 Brief Information Of Foam Bladder Tank 

Minshan foam systen baldder tanks provide accurate, dependable and cost-effective foam fire protection for a variety of flammable harzard areas, with no external power other than water pressure. Water is applied to the outside surface of the bladder, displacing foam concentrate inside the baldder, which is injected into the water stream .

Bladder tank consists of balanced-pessure proportioning systems, tank, bladder, inlet series, outlet series, pressure guage, exhaust system and pipe system, which is often installed on helicopter desks, small aircraft hangers, storage facilities, warehouses, power plant and other place. Minshan tanks are avaliable in vertical and horizontal type configurations .

  Horizontal Bladder Tank 

The tank shell is constructed of steel , complying with China common specfications and prossessing a tensile strength of no less then 70,000 psi. The circumferential as well as longitudinal body seam are welded by machine. The tank interior welds and edges are ground smooth.

The tank shell water inlet and water drain is screened to prevent bladder blow out.

The vartical tank assembly is supported by three legs with access to the bladder drain valve and the tank shell fill valve. Three legs are anchoring for the tank. The horizontal assembly is supported on two saddles weled to the tank and fitted with anchoring holes.

Vertival Foam Bladder Tank 

When the water go through the pressure reducing orifice, it will create a pressure difference in the front and behind the pressure reducing orifice. The pressure is higher in front of the pressure reducing orifice, and most of the high pressure water goes though the pressure reducing orifice, and a little water goes through the water inlet pipe, and goes into the tank, then extrude the capsule. The extruded foam concentrate goes out of the capsule through the outlet pipe, and goes into the proportioner, mixed with the water, and become water-foam mixed water, goes through the fire fighting pipe into the foam nozzle, mixed with air, then become foam to put out the fire!

 Characteristic:

1. The system doesn't need to be individually configured foam pump, the pressure can be directly borrowed from the fire foam liquid water drive, saving the costs.
2. Ensure optimum foam mixing ratio, so the fire quickly and reliably.
3. The pressure loss is small, to ensure that the end of the foam system to produce the desired pressure equipment.
4.The foam concentrate and water through the capsule isolation, and can be use several time.
5. Easy operation and maintenance, small footprint, and can be automatic control.
6. There are a variety of foam concentrate tank capacity and equipped with different flow proportioner to meet the needs of a variety of foam generating equipment.
7. It can be widely used in low, medium and high expansion foam fire extinguishing systems.
