The present invention discloses a special pipeline resistance firearm, and an outer shell including the flame arrester, both ends of the inner shell and the outer shell is provided with a flange, the inner shell has a fire retardant core, fire retardant core on the inner shell is arranged in the lower ends of the steel wire and the fire retardant core are respectively arranged on both sides of the fixing ring and the left side positioning ring. The partition is arranged between the fire resistance between the core and the positioning ring and the fire retardant core and a fixing ring, and the upper end of the other end of the lower shell shell is provided with a heating medium entrance. The invention has the advantages that the fire retardant core on the inner shell is arranged in the lower ends of the steel belt, left and right ends of the fire retardant core also has side baffle, the fluid resistance small fire, the fire resistance of steel ball can prevent high-speed flame, no blockage, good fire resistance.
【技术实现步骤摘要】
本专利技术涉及一种阻火器,尤其涉及一种管道专用阻火器。
技术介绍
目前常用的阻火器,是由金属网制成的,金属网的层数和网孔目数直接关系到阻火性能。这种结构的阻火器对流体阻火力大,且易堵塞,阻火性能也差,只适于阻止低速火焰。因此,需要提供一种新的技术来解决上述问题。
技术实现思路
本专利技术的目的是提供一种阻火性能好的管道专用阻火器。本专利技术采用的技术方案是: 管道专用阻火器,该阻火器包括内壳和外壳,所述内壳和外壳的两端设有法兰盘,所述内壳内具有阻火芯,所述阻火芯上下两端的内壳内设有钢丝带,所述阻火芯左右两侧分别设有定位环和固定环,所述阻火芯和定位环之间以及阻火芯和固定环之间均设有侧隔板,所述外壳一端上部和外壳另一端下部均开有伴热介质出入口。所述阻火芯为阻火钢球。所述钢丝带具有三角形沟槽。所述隔板由金属网交叠而成。本专利技术的优点是:阻火芯上下两端的内壳内设有钢丝带,阻火芯左右两端还具有侧隔板,对流体阻火力小,阻火钢球可以阻止高速火焰,不易堵塞,阻火性能好。附图说明下面结合附图和具体实施方式对本专利技术作进一步详细描述。图1为本专利技术的结构示意图。其中:1、内壳,2、外壳,3、法兰盘,4、阻火芯,5、钢丝带,6、定位环,7、固定环,8、侧隔板,9、伴热介质出入口。具体实施例方式如图1所示,本专利技术的管道专用阻火器,该阻火器包括内壳I和外壳2,内壳I和外壳2的两端设有法兰盘3,内壳I内具有阻火芯4,阻火芯4上下两端的内壳I内设有钢丝带5,阻火芯4左右两侧分别设有定位环6和固定环7,阻火芯4和定位环6之间以及阻火芯4和固定环7之间均设有侧隔板8,外壳2 —端 ...
【技术保护点】
管道专用阻火器,其特征在于:该阻火器包括内壳和外壳,所述内壳和外壳的两端设有法兰盘,所述内壳内具有阻火芯,所述阻火芯上下两端的内壳内设有钢丝带,所述阻火芯左右两侧分别设有定位环和固定环,所述阻火芯和定位环之间以及阻火芯和固定环之间均设有侧隔板,所述外壳一端上部和外壳另一端下部均开有伴热介质出入口。
