新型防爆控制箱用防爆阻火器
本技术涉及一种阻火器,具体涉及一种防爆控制箱用防爆阻火器。
技术介绍
煤矿、燃气等危险场所防爆控制箱中广泛使用防爆阻火器,现有防爆控制箱用防爆阻火器包括阻火器座套、阻火片Ⅰ、阻火片压套,阻火器座套设有阶梯通孔,阻火片Ⅰ从阻火器座套阶梯通孔大端塞装在阶梯通孔中部,阻火片Ⅰ粘结在阻火器座套阶梯通孔端面上,阻火片压套伸入阻火器座套阶梯通孔大端,并螺纹连接,阻火片压套端面抵压阻火片Ⅰ端面。这种防爆阻火器尽管能起到阻火作用,但也阻挡了管路的通气状态。
技术实现思路
本技术针对现有技术的不足,提出一种能在阻火的同时,仍能使管路处于通气状态的新型防爆控制箱用防爆阻火器。本技术通过下述技术方案实现技术目标。新型防爆控制箱用防爆阻火器,包括阻火器座套、阻火片Ⅰ、阻火片压套;所述阻火器座套设有阶梯通孔,阻火片Ⅰ从阻火器座套阶梯通孔大端塞装在阶梯通孔中部,阻火片Ⅰ粘结在阻火器座套阶梯通孔端面上;所述阻火片压套伸入阻火器座套阶梯通孔大端,并螺纹连接,阻火片压套端面抵压阻火片Ⅰ端面;其改进之处在于:所述阻火片Ⅰ为柱状构件,采用金属粉末冶金高温烧结成型,所述金属粉末颗粒大小为60-90目;所述阻火片Ⅰ外壁与阻火器座套阶梯通孔内孔间隙配合。上述结构中,所述阻火片压套端面、阻火片Ⅰ端面之间设有阻火片Ⅱ,阻火片压套端面抵压阻火片Ⅱ端面。本技术与现有技术相比,具有以下积极效果:1、阻火片Ⅰ为柱状构件,采用金属粉末冶金高温烧结成型,金属粉末颗粒大小为60-90目,阻火片Ⅰ外壁与阻火器座套阶梯通孔内孔间隙配合,由于金属粉末冶金高温烧结成型的阻火片具有较好的透气性,因此,本 ...
