消防工程中常用的开放式洒水喷头有开放式、水帘式和喷淋式三种。下面就为大家简单的说一下相关内容。

There are three types of open sprinkler heads commonly used in fire engineering: open sprinkler, water curtain sprinkler and sprinkler sprinkler. Let's briefly talk about the relevant content.

1.打开喷头。这种类型的洒水器是没有释放机构的洒水器。与封闭式喷头的区别在于没有感温元件和密封部件。它通常用于雨淋灭火系统。

1. turn on the nozzle. This type of sprinkler is a sprinkler without a release mechanism. The difference from the closed sprinkler is that there are no temperature sensing elements and sealing parts. It is usually used in deluge extinguishing systems.

2.水幕喷头。该喷嘴喷出的水呈均匀的水幕状，起到阻火、隔火的作用。

2. water curtain nozzle. The water ejected from the nozzle is in the shape of a uniform water curtain, which plays the role of fire resistance and fire separation.

3.喷嘴。这种喷头喷出小水滴，总喷水面积比普通喷头大几倍。由于吸热面积大，冷却效果强，水雾热汽化形成的大量水蒸气对火焰也有窒息作用。喷嘴主要用于细水雾系统，中速型多用于设备整体的冷却和灭火，高速型多用于带油的冷却和灭火设备。

3. nozzle. The sprinkler sprays small water drops, and the total spraying area is several times larger than that of the ordinary sprinkler. Due to the large heat absorption area and strong cooling effect, a large amount of water vapor formed by the thermal vaporization of water mist can also asphyxiate the flame. The nozzle is mainly used for water mist system. The medium speed type is mainly used for overall cooling and fire extinguishing of equipment, and the high-speed type is mainly used for cooling and fire extinguishing equipment with oil.

此外，我们还可以了解开式喷头和闭式喷头的区别：

In addition, we can also understand the difference between open sprinkler and closed sprinkler:

自动喷水灭火系统中的喷头分为开放式和封闭式两种。喷洒方式分为上喷、下喷和侧喷三种。开放式洒水器一般用于雨淋自动灭火系统，而封闭式洒水器一般用于自动洒水系统。两者的安装方法相同，但系统的工作原理不同。在不同环境温度场所设置喷嘴时，应严格根据环境暴露情况选择喷嘴等级。

Sprinkler heads in automatic sprinkler system are divided into open type and closed type. There are three spraying methods: up spraying, down spraying and side spraying. Open sprinkler is generally used for deluge automatic fire extinguishing system, while closed sprinkler is generally used for automatic sprinkler system. The installation method is the same, but the working principle of the system is different. When setting nozzles in places with different ambient temperatures, the nozzle grade shall be selected strictly according to the environmental exposure.

封闭式喷头：内置玻璃球，玻璃球承载喷头垫片。发生火灾时，球内的液体受热膨胀，压力升高。当压力达到规定值时，玻璃球爆裂，垫片失去支撑。加压的水喷出了火。它用于消防喷淋系统。消防喷淋系统管网有水压。当玻璃球爆裂时，管网中的水会自动喷出，形成火灾。

Closed sprinkler: built in glass ball, which carries sprinkler gasket. In case of fire, the liquid in the ball will expand and the pressure will rise. When the pressure reaches the specified value, the glass ball bursts and the gasket loses support. Pressurized water spurted fire. It is used for fire sprinkler system. There is water pressure in the pipe network of the fire sprinkler system. When the glass ball bursts, the water in the pipe network will automatically spray out, forming a fire.

开放式洒水头：无内置玻璃球，出水口为开放式，水压通过洒水头直接喷出，开放式洒水头由本体、支架和防溅板组成。一般用于雨淋灭火系统，与火灾自动报警系统配合使用。当现场发生火灾时，火灾自动报警系统收到信号后控制雨淋阀打开，水压通过喷头直接喷出，形成大范围灭火。

Open sprinkler head: there is no built-in glass ball. The water outlet is open. The water pressure is directly sprayed through the sprinkler head. The open sprinkler head is composed of body, support and splash plate. It is generally used for deluge fire extinguishing system and is used in conjunction with automatic fire alarm system. When a fire occurs on site, the automatic fire alarm system will control the deluge valve to open after receiving the signal, and the water pressure will be directly sprayed through the nozzle to form a large-scale fire extinguishing.

川消小编提醒，开放式喷头和封闭式喷头的区别只是少了一个由热敏元件组成的释放机构。两者具有相同的流动特性和喷雾曲线。封闭式喷头是一个或多个喷头喷水，开放式喷头是整个区域的所有喷头一起喷水，封闭式喷头一个接一个地爆破喷水。

Chuanxiao Xiaobian reminded that the difference between open sprinkler and closed sprinkler is that there is only a release mechanism composed of thermal elements. Both have the same flow characteristics and spray curves. The closed sprinkler is one or more sprinklers spraying water, the open sprinkler is all sprinklers spraying water together in the whole area, and the closed sprinkler is blasting and spraying water one by one.
