Supply vertical foam tank pressure foam tank foam proportional foam tank

Description :

　　The pressure type foam proportional mixing device is used to store foam extinguishing agent, and through the function of the pressure type proportional mixer, the foam extinguishing agent in the fire water supply replacement device is mixed with the water supply in a certain proportion to form a foam mixture, which is supplied to the foam generator, foam nozzle, foam gun and other end extinguishing equipment.

　　This product is equipped with water pump and corresponding foam liquid and generator, which can form various low, medium and high expansion foam fire extinguishing systems, foam spray and water film forming foam fire extinguishing systems.

　　Executive standard: General Technical Conditions for foam Extinguishing Systems and Components (GB20031-2005)

　　Product composition and working principle

　　The pressure type foam proportioning device is mainly composed of foam liquid storage tank with and PHY type pressure type foam proportioning device made by the Venturi principle. When the water flow in the system pipeline passes through the pressure reducing orifice plate of the proportional mixer, a pressure difference will be formed at the front of the orifice plate. Part of the water at the high pressure enters the tank and is squeezed. The foam liquid in the tank is squeezed to the low pressure of the system pipe network and mixed with water to form a foam mixture. The foam generator is used to generate corresponding foam to extinguish the fire.

　　The foam mixture formed by replacement can maintain the mixing proportion under the condition of flow and pressure changes, so that sufficient foam can be generated during fire extinguishing. At the same time, it also makes the pressure drop loss of this product very small, ensuring that the foam ejected has large energy and strong penetration, improving the fire extinguishing effect.

　　classification

　　Pressure type foam proportioning devices usually have the following classification methods:

　　① According to the storage form of foam concentrate, it can be divided into: proportional mixing device and non proportional mixing device;

　　② According to the structural form of the storage tank, it can be divided into horizontal proportional mixing device and vertical proportional mixing device;

　　③ According to the number of proportional mixers, they are divided into single proportional mixer mixing devices and multi proportional mixers (2 or 4) for mixing

　　Installation and usage instructions

　　1. Installation of the device

　　The direction of pressure water flow during installation should be consistent with the direction indicated by the arrow on the proportional mixer on the device. Pressure gauges, one-way valves, control valves, pipeline filters, etc. should be installed before the proportioning mixer;

　　The foam tank shall be fixed with the ground foundation.

　　2. Filling method of foam concentrate

　　Close all valves, open two exhaust valves, fill 1/3 to 1/2 of the tank water between the tank and the tank through the water inlet pipe and the drain port, then open the liquid filling port, insert an inch rubber pipe from the liquid filling port to the tank bottom, inject foam extinguishing agent into the tank through the crossover pipe, open the drain valve after water is discharged from the exhaust port, and drain water at a flow similar to the flow of foam liquid filling until the foam liquid is fully filled. After filling is completed, close the filling port and drainage valve, open the inlet valve, and slowly fill the space between the tank and the tank with water until water flows out from the exhaust port. Close the exhaust valve and inlet valve, and then rinse the scattered fire extinguishing agent outside the device with clean water.

　　3. The function of the device

　　A proportional mixer should be used within the specified pressure and mixed liquid flow range. The mixing ratio of the mixed liquid output by the proportional mixer can be automatically adjusted within the specified flow range with changes in water flow rate to maintain a stable mixing ratio;

　　When the pressure water passes through the proportional mixer, open the inlet valve for storage. At this time, observe the pressure gauge. When the pressure reaches the design pressure value, immediately open the outlet valve, and the device will start working;

　　The C device should be installed indoors or in a place with a protective shed to avoid direct sunlight and rain. The ambient temperature should be maintained within the range of 0-40 ℃.
