product description

Product introduction

PHYM series tank pressure type foam proportion mixing device is a displacement type foam proportion mixing device. When the pressurized water passes through the proportional mixer, the water and the foam liquid can be automatically mixed according to a certain ratio, and the foam mixed liquid can be output for the air foam generator, air foam gun and other foaming and spraying devices to generate air foam for fire extinguishing. The feature of this device is that a diaphragm (capsule) made of synthetic rubber is installed in the storage tank, which separates the foam liquid from water, and is suitable for various low expansion foam liquids. After the fire extinguishing or commissioning, the remaining foam liquid can continue to be used. . The pressure type foam proportion mixing device is suitable for foam fire extinguishing systems that require both small flow and large flow. It is not necessary to use a proportional mixer in different regions, simplifying pipeline layout, reducing costs and optimizing performance.

Application range:

It is widely used to extinguish liquid fires of Class A, B and C. It is an oil refinery, chemical plant, oil depot, oil field, oil terminal, oil tanker, underground parking garage, aircraft hangar, airport, fuel oil boiler and other places.

Structure and working principle

Pressure type foam proportional mixing device is mainly composed of foam storage tank, rubber capsule, pressure proportional mixer, safety valve, water inlet pipe, liquid outlet pipe, drain valve, drain valve, exhaust valve and so on. When the pressure water source of the fire water pump enters the decompression orifice plate of the proportional mixer through the water supply pipe, a pressure difference will be formed before and after the orifice plate. Most of the pressure water is sprayed to the diffusion pipe through the nozzle, and a low-pressure mixing chamber is formed between the nozzle and the diffusion pipe. A small part of the water at high pressure enters the tank through the water inlet pipe, squeeze the capsule, squeeze the foam liquid in the capsule from the liquid outlet pipe, enter the low-pressure mixing chamber of the proportional mixer, and mix with most of the water flowing through the nozzle The foam mixture is formed and delivered to spray equipment such as foam generation to generate air foam for fire extinguishing.

Note:

1) The direction of the water flow of the proportional mixer can be adjusted according to user design needs, which must be declared in advance;

2) The diameter of the tank can also be adjusted appropriately according to the user's site, which must be declared in advance;

3) The volume of the tank is different, and the location of water discharge and exhaust will differ from the figure, whichever is the actual object.
