高压细水雾喷头根据不同的应用场所，可分为开式喷头、闭式喷头、高大空间专用喷头、超细水雾喷头等100多种不同应用的高压细水雾喷头。那么你知道为什么闭式的细水雾喷头应用较少吗？下面川消小编为您解答。

High pressure water mist sprayers can be divided into more than 100 types of high pressure water mist sprayers with different applications, such as open type sprayers, closed type sprayers, special sprayers for large and large spaces, ultra-fine water mist sprayers, etc. Do you know why closed water mist nozzles are less used? Now, let's answer for you.

闭式喷头之所以应用较少，原因是它是一种常闭喷头，喷头的感温、闭锁装置只有在预定的温度环境下，才会爆破，开启喷头。所以火灾发生时，闭式喷头只有身处于火焰之中，或临近火源时，才会开启出水灭火。

The reason why the closed sprinkler is seldom used is that it is a normally closed sprinkler. The temperature sensing and locking devices of the sprinkler will burst and open the sprinkler only under the predetermined temperature environment. Therefore, when a fire occurs, the closed sprinkler will only open the water to extinguish the fire when it is in the flame or near the fire source.

另外，闭式喷头的可靠性不高，受到外力可能会破碎，造成误喷射，所以只能设置在一些对水不敏感的部位；还有闭式喷头只要一爆破，用过一次后就不能再重复使用，因此费用方面也要考虑进去。所以，闭式喷头只适用于闭式系统。

In addition, the reliability of the closed sprinkler is not high, which may be broken by external forces, resulting in spurting by mistake, so it can only be set in some parts that are not sensitive to water; Also, once the closed sprinkler is blasted, it cannot be reused after being used once, so the cost should also be taken into account. Therefore, the closed sprinkler is only applicable to the closed system.

此外使用之前要了解该产品的注意事项，如：

In addition, you should know the precautions of the product before use, such as:

应严格按照环境高温度来选定喷头温级。在不同的环境温度场所设置喷头时，喷头的公称动作温度宜比环境高温度高30℃。

The nozzle temperature level shall be selected in strict accordance with the high ambient temperature. The nominal operating temperature of the nozzle should be 30 ℃ higher than the high ambient temperature when the nozzle is set at different ambient temperature locations.

在有腐蚀性介质存在的场所，应选用经防腐处理的喷头，或选用耐腐蚀的玻璃球洒水喷头。

In places with corrosive media, the nozzle with anti-corrosion treatment or the anti-corrosion glass ball sprinkler shall be selected.

建筑物、构筑物设有自动喷水灭火系统时，应有库存备用喷头，其数量不应少于总安装个数的1%，且每种类型和不同温标的备用喷头数均不应少于10个。等等。

When buildings and structures are equipped with automatic sprinkler systems, they shall have spare sprinklers in stock, which shall not be less than 1% of the total number of sprinklers installed, and the number of spare sprinklers of each type and different temperature scales shall not be less than 10. wait.
