Dongyue pressure foam proportioning device vertical horizontal fire foam tank PHYM foam tank

Description :

　　PHYM series pressure type proportioning device is composed of foam liquid storage tank, pressure type proportioner, safety valve, control valve and some auxiliary parts. When the fire pressure water flows through the equipment, the proportional mixer divides its proportion, and a small part of the water flows into the interlayer of the foam liquid storage tank. The replaced foam liquid is mixed with the fire water of the other main pipes to form a certain proportion of foam liquid mixture, which is delivered to the foam generating equipment. PHYM series pressure type proportional mixing device is applicable to all kinds of foam liquid with a mixing ratio of 3%/6%.

　　The pressure type foam proportioning device is used to store foam extinguishing agent and replace foam extinguishing agent through the pressure type foam proportioner using the water supply of the pump set, and mix with the water supply in a certain proportion to form foam mixture.

　　The pressure type foam proportional mixing device is a common foam extinguishing equipment at present. The pressure type foam proportioning device is easy to install, use and maintain, with excellent built-in corrosion resistance, relatively economical cost, stable and reliable performance, and is especially suitable for medium and small flow foam fire extinguishing systems. Mainly applicable to places where flammable or combustible liquids are produced, stored, transported, and used; Fire hazard areas such as petrochemical enterprises, oil depots, loading and unloading docks, ship docks, oil extraction platforms, aircraft hangars, and automobile garages.

　　The pressure type foam proportioning device can be divided into horizontal, vertical, with, without, single proportioning mixer, double proportioning mixer, etc. according to the structural type. Users can choose according to the actual configuration needs and the location of the installation space.

　　structure

　　1、 This series of products mainly consists of tanks, proportional mixtures, inlet pipes, outlet pipes, drainage valves, discharge valves, safety valves, and pressure gauges. Each pipeline is equipped with a valve

　　Pressure gauges are installed on the doors and inlet pipelines, and are installed inside the tank. The inner cavity and tank cavity are independent of each other.

　　2、 Working principle

　　The pressure water enters the tank through the water pipe, and produces pressure extrusion to extrude the foam liquid through the liquid outlet pipe, so that the foam liquid is automatically mixed with the water in the proportioner in a certain proportion

　　The mixed liquid flows through the air foam generator and foam gun (monitor) to eject foam for fire extinguishing.

　　3、 Main purpose

　　This series of products is widely used in oil depots, petroleum, chemical, natural gas, power plants, textile cotton and linen, docks, gas stations, warehouses, high-rise buildings, fuel boilers, underground garages and other fields

　　So.

　　Foam fire extinguishing device is a new and efficient fire fighting product specially developed for important places such as garage, parking lot, fuel boiler room, etc.

　　The key component of the system, the self-adjusting foam proportioner, is a technological innovation of foam fire extinguishing equipment. It can always maintain a certain mixing ratio within a large flow range.

　　Pressure type proportional mixing device (horizontal) Fixed foam fire extinguishing device Features:

　　(1) Foam extinguishing agent has film forming property and film self-healing property. Strong resistance to reignition;

　　(2) Foam liquid can be stored for 20 years without deterioration. Generally, foam concentrate can only be stored for 2 years;

　　(3) High firefighting effectiveness. 2~3 times of general foam extinguishing agent;

　　(4) Applicable to non aspirating foam injection device;

　　(5) Suitable for foam mixture with large flow range and accurate mixing ratio, suitable for 3% and 6% foam solutions;

　　(6) Low pressure loss;

　　(7) Flexible movements. Belonging to mechanical transmission;

　　(8) Corrosion resistance. The components are made of stainless steel and copper alloy;

　　(9) Foam liquid storage tank is built in to isolate water and foam liquid, which can be used continuously for many times;

　　(10) Can be used in conjunction with automatic sprinkler fire extinguishing systems and can achieve automation; (11) The supply of foam liquid is realized by water source pressure, without additional foam power source;

　　(12) Suitable for the renovation of automatic sprinkler fire extinguishing systems. Only foam proportioner and foam concentrate tank need to be added.
