The vertical foam tank fire extinguishing system of PHMY XX-Y pressure (foam) proportional mixing device is composed of pressure tank, capsule, proportional mixer, safety valve, exhaust valve, pressure gauge, check valve and various control valves and pipes. Pressurized water is supplied by a pump, and the foamed liquid is replaced with a certain ratio to form a foamed mixed liquid. When the proportional mixing device is used within the rated inlet pressure range (0.4 MPa to 1.0 MPa), the mixing ratio of the foam liquid to water does not change with the fluctuation of the inlet water flow, thereby ensuring the stable and reliable mixing ratio. Because the capsule separates the foam liquid from water, the foam liquid is not used up once, and it can be used next time with stable and reliable mixing accuracy. The device is suitable for a wide range of flow, pressure and small pressure loss, and has been widely used in various high, medium and low multiple foam fire extinguishing systems. According to the structure, it can be divided into two types: horizontal and vertical.
。 A wide range of foam liquids can be used: all types of fire extinguishing foam liquids can be used, including hydrofilm, protein, fluoroprotein foam, and solvent-resistant foam fire extinguishing agents .
于正压力 比例混合装置的储罐储存泡沫液时间长，使用后剩余的泡沫可以继续使用，使其成本大大降低。 Low cost: Because the storage tank of the positive pressure proportional mixing device stores the foam liquid for a long time, the remaining foam after use can continue to be used, which greatly reduces its cost.
Long life: The foam and water are separated by capsules, which avoids the contact between the foam and the steel tank and corrodes the tank, thereby extending the life of the tank.
Wide application: This device, pressure water, foam generator (foam nozzles, foam guns, foam cannons, etc. are also alternative foam generators) and spray equipment constitute a foam fire extinguishing system, which is mainly used to extinguish oil fires. It has safety, reliability and fire extinguishing efficiency. Higher advantages. 化工及油 库、橡胶制造、油船、煤矿、汽车库、机场和燃油锅炉房等消防场所 。 Widely used in petroleum, chemical and oil depots , rubber manufacturing, oil tankers, coal mines, garages, airports and fuel boiler rooms and other fire-fighting places .
表示意义如下： 1 The meaning of the pressure (foam) proportional mixing device is as follows:
标记示例：容积为3000L的卧式泡沫液储罐，进口段水压力为 0.75 Mpa时，比例混合体流量为32L ／ S，该 压力（泡沫）比例混合器的 型号表示为 PHYM32/30 。 2 Marking example: Horizontal foam liquid storage tank with a volume of 3000L, when the water pressure at the inlet section is 0.75 Mpa, the flow rate of the proportional mixture is 32L / S, and the model of the pressure (foam) proportional mixer is PHYM32 / 30
。 Applicable to 3% or 6% foaming liquids with various mixing ratios. This device is widely used in oil storage tank areas, chemical plants, aircraft hangars, oil fields, oil power plants, boiler rooms, underground garages, dangerous goods warehouses, and chemical products. Warehouses, rubber manufacturing, oil tankers, coal mines, airports, and oil fired boiler rooms . And other places and water spray-foam combined system.
比例混合体后 ，大部分水通过比例混合体孔板，进入后段低压区，少部分水通过进水阀门A进入到钢罐1内，水再挤压胶囊2，囊内泡沫液在压力水的挤压下，通过出液阀门 B 进入比例混合装置的低压区，在低压区，水和泡沫按比例进行自动混合，形成泡沫混合液，经管道输送给泡沫产生器，经由泡沫产生器出来的混合液变成空气泡沫，空气泡沫覆盖燃烧物表面进行灭火。 As shown in Figure 1, after the pressure water enters the proportional mixture , most of the water passes through the orifice of the proportional mixture and enters the low-pressure area at the rear. A small part of the water enters the steel tank 1 through the water inlet valve A, and the water is squeezed again. Capsule 2, the foam liquid in the capsule is squeezed by the pressure water and enters the low-pressure area of the proportional mixing device through the outlet valve B. In the low-pressure area, water and foam are automatically mixed in proportion to form a foam mixed liquid, which is sent to the pipeline. The foam generator turns the mixed liquid from the foam generator into air foam, and the air foam covers the surface of the burning object to extinguish the fire.
