Special foam fire extinguishing device for storage and petrochemical industry Price proportion mixing device of pressure type foam fire extinguisher

Description :

　　structure

　　The PHYM series products mainly consist of tanks, proportional mixtures, inlet pipes, outlet pipes, drainage valves, drain valves, safety valves, and pressure gauges. Each pipeline is equipped with a valve, and a pressure gauge is installed on the inlet pipeline, which is installed inside the tank. Its inner cavity and tank cavity are independent of each other.

　　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 and the water in the proportioner are automatically mixed into a mixed liquid in a certain proportion, and the foam is sprayed out through the air foam generator and the foam gun (monitor) to extinguish the fire.

　　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 places.

　　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 in a large flow range. In addition to the fire extinguishing effect of the protective film of the water film-forming foam extinguishing agent, it is suitable for non aspirating foam injection devices, making the system have the following significant characteristics:

　　(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.

　　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 ℃.

　　maintenance

　　After the installation and acceptance of the device, there should be full-time or part-time firefighters to inspect, maintain and upkeep the device:

　　1. Regularly inspect the storage tank and proportioner every month to ensure that there are no leaks, rust, mechanical damage, etc;

　　2. Test the foam liquid in the tank every half a year to ensure that the chemical composition and performance of foam liquid meet the standard requirements;

　　3. Open the ball valve of the level gauge to observe the level of foam. After observation, close the ball valve of the level gauge in time.
