Abstract

本实用新型涉及一种看火门盖。它包括门盖本体(1)、所述门盖本体(1)内填充有耐火衬里(3),耐火衬里(3)内设置有保温钉(3),所述保温钉(3)的两端与门盖本体(1)的内壁塞焊连接,所述耐火衬里(3)的温度等级为1260度。本实用新型一种看火门盖,由于看火门盖盖内设置有衬里,且衬里内设置有保温钉,保温钉两端与门盖本体的内壁塞焊连接,因此能有效隔绝炉膛的温度,降低热损失,提高加热炉的热效率。

Description

看火门盖
技术领域
本实用新型涉及一种看火门盖,属于燃烧设备技术领域。
背景技术
目前加热炉的看火门盖由于不设耐火衬里或者耐火衬里的隔热效果差,导致看火门盖的温度高,导致加热炉热损失加大,热效率降低。
发明内容
本实用新型的目的在于克服上述不足,提供了一种隔热效果好的看火门盖。
本实用新型的目的是这样实现的:
一种看火门盖,其特点是:所述看火门盖包括门盖本体、所述门盖本体内填充有耐火衬里,耐火衬里内设置有保温钉,所述保温钉的两端与门盖本体的内壁塞焊连接,所述耐火衬里的温度等级为1260度。
与现有技术相比,本实用新型的有益效果是:
本实用新型一种看火门盖,由于看火门盖盖内设置有耐火衬里,且耐火衬里内设置有保温钉,保温钉两端与门盖本体的内壁塞焊连接,因此能有效隔绝炉膛的温度,降低热损失,提高加热炉的热效率。
附图说明
图1为本实用新型一种看火门盖的结构示意图。
图2为图1的A-A剖视图。
图3为图2的B-B剖视图。
图中:
门盖本体1,
耐火衬里2,
保温钉3。
具体实施方式
参见图1-3,本实用新型涉及一种看火门盖,它包括门盖本体1、所述门盖本体1内填充有耐火衬里3,耐火衬里3内设置有保温钉3,所述保温钉3的两端与门盖本体1的内壁塞焊连接,所述耐火衬里3的温度等级为1260度。
