Manufacturer of foam extinguishing equipment Horizontal foam extinguishing device Pressure foam extinguisher

Description :

　　The YM series pressure type proportioning device produced by Shandong Dongyue Crane Fire Fighting Equipment Manufacturing Co., Ltd. is composed of foam tank, pressure type proportioner, diaphragm, water inlet pipe, liquid outlet pipe and control valve. When the pressure water flows through the proportional mixer of the device, the water and foam can be automatically mixed in a certain proportion, and the foam mixture is output to the foam generator, foam monitor, foam nozzle, foam gun and other spraying equipment to generate and spray air foam for fire extinguishing.

　　The device can form a fixed (or semi fixed) foam extinguishing system with fire pump (or fire truck), foam generation and spraying equipment. Widely used for extinguishing Class A, B, and C liquid fires, it is safe and reliable. The advantages of high fire extinguishing efficiency make it a commonly used fire-fighting equipment in places such as oil depots, refineries, chemical plants, oil fields, docks, oil tankers, aircraft hangars, airports, and fuel boiler rooms.

　　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.

　　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.

　　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.
