近年来，闭式泡沫水喷淋系统作为一种有效的灭火系统在许多化工工程得到了运用。与自动喷水灭火系统和泡沫喷淋系统的比较自动喷水灭火系统中的闭式系统有湿式，干式。下面川消小编来讲讲闭式泡沫水喷淋灭火系统的应用范围。

In recent years, closed foam water spray system as an effective fire extinguishing system has been used in many chemical projects. Compared with the automatic sprinkler system and foam sprinkler system, the closed system in the automatic sprinkler system includes wet type and dry type. Next, Chuanxiao Xiaobian will talk about the application scope of closed foam water sprinkler system.

闭式泡沫水喷淋灭火系统的应用范围：

Application scope of closed foam water sprinkler system:

该泡沫灭火装置广泛用于油库、化工厂、机库、油田、燃油锅炉、地下车库等场所。

The foam fire extinguishing device is widely used in oil depots, chemical plants, hangars, oil fields, oil fired boilers, underground garages and other places.

闭式泡沫水喷淋灭火系统，包括进水总管、湿式报警阀、连接管、压力泄放阀、第二连接管、比例混合器、进水管、出液管、泡沫液控制阀以及泡沫罐体，在进水总管的出水口处与闭式喷淋管网连接，具有洒水喷头，有火灾发生时，洒水喷头会爆破，此时湿式报警阀打开，水进入延时器和连接管，水力警铃报警，压力开关动作，启动消防水泵，为进水总管加水。

The closed foam water spray fire extinguishing system includes a water inlet header, a wet alarm valve, a first connecting pipe, a pressure relief valve, a second connecting pipe, a proportioner, a water inlet pipe, a liquid outlet pipe, a foam liquid control valve and a foam tank. The water outlet of the water inlet header is connected to the closed spray pipe network and has a sprinkler. In case of fire, the sprinkler will burst, and the wet alarm valve will open, When the water enters the delay device and the first connecting pipe, the hydraulic alarm bell gives an alarm, the pressure switch acts, and the fire pump is started to add water to the water inlet header.

连接管的水经过压力泄放阀，使得压力泄放阀打开，此时第二连接管中的水进行泄压，使得泡沫液控制阀开启，与此同时，进水总管的水从进水管进入到金属壳体和胶囊罐体之间的间隙，并且挤压胶囊罐体，使得胶囊罐体内的泡沫从出液管进入到比例混合器中，从而使得比例混合器中的水与泡沫进行混合，然后混合液从闭式喷淋管网的洒水喷头喷出，即可进行灭火。但是由于喷淋管网固定因此从洒水喷头喷出的水的范围也被固定，灭火范围也受到限制。

The water in the first connecting pipe passes through the pressure relief valve to open the pressure relief valve. At this time, the water in the second connecting pipe is relieved to open the foam liquid control valve. At the same time, the water in the water inlet pipe enters the gap between the metal shell and the capsule tank from the water inlet pipe and extrudes the capsule tank, so that the foam in the capsule tank enters the proportioner from the liquid outlet pipe, So that the water in the proportioner is mixed with foam, and then the mixed liquid is sprayed from the sprinkler of the closed sprinkler network to extinguish the fire. However, since the sprinkler pipe network is fixed, the range of water ejected from the sprinkler is also fixed, and the fire extinguishing range is also limited.

总之，由于化工生产的原料，成品大多为易燃，易爆物品，随着生产规模的不断扩大，设备和建筑物的标准的提高，一旦发生火灾，造成的损失将更为巨大。因此，设置，有效和合理的消防措施对化工工程尤其重要。以上内容希望能给您帮助，更多信息获取就来我们网站http://www.cx-fire.com吧。

In short, as the raw materials and finished products of chemical production are mostly inflammable and explosive materials, with the continuous expansion of production scale and the improvement of equipment and building standards, once a fire occurs, the losses will be even greater. Therefore, it is particularly important for chemical engineering to set up safe, effective and reasonable fire protection measures. I hope the above contents can help you.
