Pressure foam proportioning device

Pressure foam proportioning device
 

Product description:


Pressure foam proportioning device main body, capsules, proportioner, inlet pipe, outlet pipe, drain valve, drain valve, safety valve, pressure gauge each line are equipped with a valve, water pipeline On equipped with a pressure gauge, a capsule fitted in the tank body, the cavity and the tank chambers are independent. It is used to store foam extinguishing agent, and by the action of pressure proportioning mixer, the fire water stored in the device replacement foam extinguishing agent, and with a certain proportion of water mixed foam mixture in the form of the apparatus for forming the structure of the tank is divided into: horizontal and vertical ratio proportioning device mixing devices; mixer divided by the number of proportion: Single the proportion of mixer devices and multi-mixer ratio (2 or 4) mixing device. working principle Pressure foam proportioning device with the capsule consists of foam concentrate pressure tank and use the venturi principle made PHY type pressure proportioner composition, when the system of water flowing through the pipe network proportioner pressure plate, before and after the pressure plate will form part of high pressure water (3% or 6%) into the water tank through the foam into the tank; Squeeze capsule; the capsule through the foam in the foam liquid tank tube squeezed to a low pressure at the mixing ratio of the mixer with water to form foam mixture; forming a foam mixture to foam generation output device (in; low; high-expansion foam generator; bubble gun; bubble guns, etc.) is mixed with air to produce foam fire extinguishing . Features 1. Foam tank mixing ratio is quite stable, accurate and reliable, can provide high-quality foam mixture. 2. Loss minimum pressure drop foam tank, foam fire extinguishing agent injection of energy, strong penetration ability to quickly extinguish the fire. 3. foam liquid savings, reduce fire costs due to separate foam tank foam liquid capsules with water, foam was not used up, the next can continue to use, but also blending accuracy stable and reliable. 4. Applicable to a wide range, regardless of high, medium and low expansion foam fire extinguishing agent can be used. automatic foam extinguishing foam proportioning system with foam applicator device can also be used sprinklers.
