Description
技术领域
本发明涉及消防管道技术领域,特别涉及一种防火防磨损耐高温的消防水管。
背景技术
为了消防安全,国家致力于研发适用于各种场合的消防设备,消防水管因为要经受不同的环境考验消防水管因其特殊的使用环境,因此,其结构和性能上往往与普通的水管要区别对待;目前,使用的消防水管或多或少都存在一定的缺陷。
比如管子在进行救火的过程中管子的外表面直接与火焰接触,很容易造成管子被烧坏,并且由于隔热材料的原因管子外表面的温度会升高,管子外表面温度过高会对消防员身体产生危害。消防水管的防磨损效果不好,由于消防工作环境的复杂性,消防水管在进行远距离输送水源的过程中,很容易被工作环境中的尖锐物体刺破,或是由于在工作过程中对消防水管的拖拽使得水管发生磨损破裂,一旦水管产生开口管子就不能继续使用了,这样很容易造成资源的浪费,耽误救援。
发明内容
针对现有技术中存在的不足,本发明提供了一种防火防磨损耐高温的消防水管,结构简单,操作简单,生产成本低,防火,耐磨性能,耐高温,方便收放以及使用,具有良好的外部抗压性能,适用范围广,使用寿命长。
本发明是通过以下技术手段实现上述技术目的的。
一种防火防磨损耐高温的消防水管,包括金属编织网、微型热管和消防水管,所述消防水管外部包裹金属编织网,所述金属编织网与消防水管之间设有若干微型热管;所述微型热管用于降低金属编织网的温度。
进一步,所述微型热管一端与金属编织网内表面接触,所述微型热管另一端位于消防水管内;所述微型热管内设有冷却液,所述冷却液在微型热管接触的金属编织网和消防水管之间通过物理形态转换实现降温。
进一步,所述微型热管包括蒸发段、隔热段和冷凝段;所述蒸发段位于金属编织网内表面与消防水管外表面之间;所述冷凝段位于消防水管内;所述隔热段与消防水管壁厚接触。
进一步,所述微型热管包括热管金属层和毛细结构层,所述热管金属层内设有毛细结构层,所述毛细结构层内填充冷却液,通过毛细力的作用回流冷却液。
进一步,位于消防水管内的热管金属层外表面为波纹结构。
进一步,所述冷却液为二氯甲烷。
进一步,所述消防水管上阵列若干圆孔,任一所述圆孔内安装金属圆环套,所述金属圆环套内固定微型热管。
本发明的有益效果在于:
在消防过程中,消防水管进入到火势较为严峻的情况中时,火焰直接与消防水管接触,由于火焰温度较高,即使消防水管中有水流过,消防水管外表面还是容易被烧坏,导致水管漏水,通过将金属编织网包裹在消防水管的外面,利用火焰在冷却金属表面淬火的原理,可以隔绝消防水管的外表面与火焰直接接触,避免了消防水管外表面烧坏。不锈钢金属软网的冷却是通过与微型热管的蒸发段相连,微型热管与消防水管通过金属圆环套焊接在一起,冷凝段直接与水接触,当金属编织网温度高于冷却液的沸点时,通过热管的导热作用降低不锈钢金属网的温度,微型热管中使用的冷却液为二氯甲烷,沸点在40摄氏度,可以保证不锈钢金属软网的外表面温度不至于过高,达到冷却金属表面的效果,而且被冷却的不锈钢金属网与火焰接触时,更易造成火焰的淬火和产生更大的淬火距离。消防水管外面增加一层不锈钢金属软网还可以保护消防水管在长时间的使用拖拽过程中不被磨损或者扎破,延长消防水管的使用寿命,使用不锈钢金属软网,既有一定柔韧性又有一定硬度,能够保证消防水管工作时水管进水的膨胀,以及不工作时的收缩折叠。

具体实施方式
下面结合附图以及具体实施例对本发明作进一步的说明,但本发明的保护范围并不限于此。
如图1和图2所示,本发明所述的防火防磨损耐高温的消防水管,包括金属编织网1、微型热管5和消防水管2,所述消防水管2外部包裹金属编织网1,所述金属编织网1与消防水管2之间设有若干微型热管5;所述微型热管5用于降低金属编织网1的温度。所述微型热管5一端与金属编织网1内表面接触,所述微型热管5另一端位于消防水管2内;所述微型热管5内设有冷却液8,所述冷却液8在微型热管5接触的金属编织网1和消防水管2之间通过物理形态转换实现降温。
结合图2和图3,具体结构如下:采用金属编织网1将消防水管2包裹,在消防水管2的每个相聚100mm的横截面上开有八个圆孔3用来固定金属圆环套4,这每个横截面上的圆孔3与金属圆环套4通过强力胶水进行连接,使其固定在消防水管2上,金属圆环套4通过焊接的方式与微型热管的隔热段10进行连接,微型热管5这部分的结构不进行热量的交换,所以保证其厚度与消防水管2的厚度一致,微型热管的隔热段10为微型热管5工作部分之一,微型热管还包括微型热管的蒸发段9和冷凝段11。微型热管的蒸发段11与不锈钢金属软网1用焊接的方式连接,用来吸收不锈钢金属软网1的热量,并将这部分的热量通过微型热管5传递给微型热管的冷凝段11,微型热管的冷凝段11与温度较低的水流通过对流的方式直接接触;位于消防水管2内的热管金属层6外表面为波纹结构12,是为了增加接触面积,提高散热效率。所述微型热管5包括热管金属层6和毛细结构层7,所述热管金属层6内设有毛细结构层7,所述毛细结构层7内填充冷却液8,通过毛细力的作用回流冷却液8。热管金属层6用于金属的焊接连接,毛细结构层7与热管金属层6通过镶嵌的方式固定,并通过毛细力的作用回流冷却液,冷却液8在微型热管的蒸发段9和冷凝段11之间通过物理形态转换的方式来达到热量的传递。金属编织网1为304不锈钢材料,用精密编织的方式对消防水管进行包裹,用编织的方式使得不锈钢金属软网的伸缩性较好可以适应消防水管的变化,很好的隔绝火焰与消防水管的外表面直接接触。
微型热管5为吸液芯型热管,通过毛细作用来回流冷却液,使用吸液芯型热管可以不用考虑冷却液重力的影响,使得微型热管5的布置更加的方便。冷却液8的介质为二氯甲烷,使用二氯甲烷的目的是考虑到其液体沸点为40摄氏度,当金属编织网1的表面温度高于40 摄氏度时,冷却液8蒸发带走热量,汽化的冷却液在微型热管的冷凝段11被液化放出热量,保证金属编织网1温度稳定。
工作原理:本设计主要依据火焰在冷却壁面上淬火的原理,使得火焰在冷却金属表面发生淬熄,产生较大的淬火距离,降低了消防水管2的表面温度,金属编织网1也隔绝了火焰与消防水管2直接接触,保证消防水管2安全的工作环境,同时,金属编织网1增加了消防水管耐磨性,使得消防水管的适用范围更广泛,使用寿命更长。将微型热管5于金属编织网 1进行连接,微型热管5中使用的冷却液8为二氯甲烷,其化学性质稳定,沸点为40摄氏度,当金属编织网1的表面温度超过40摄氏度时,在每个相隔100mm的横截面上都有八个微型热管5发挥作用,以充分保证金属编织网1维持在一个较低的表面温度,提高消防员工作的安全性。
所述实施例为本发明的优选的实施方式,但本发明并不限于上述实施方式,在不背离本发明的实质内容的情况下,本领域技术人员能够做出的任何显而易见的改进、替换或变型均属于本发明的保护范围。
