Description

本实用新型为一种在阀体前装有防回火装置的燃气焊炬。
一般氧乙炔燃气的焊炬其防回火装置设于焊炬的尾部,但这种设置结构适用燃气范围有限,尤其对于氢氧燃气不适用,一旦出现回火会引至氢氧发生器爆炸。
本实用新型的目的在于提供一种防回火装置在阀前部的燃气焊炬。
本实用新型有燃气接头、手柄、通道及阀和焊咀部,特点是防回火装置装在阀的前端。防回火装置是由止火管及其前端的止火管座组成,可套在外壳套管内由密封圈、连接件将其与燃气通道连接固定;也可在手柄处装手柄阀,防回火装置装在手柄前端的有阀和燃气通道的中部主体内的阀前端,由连接件、密封圈将其固定在中部主体内。其中手柄阀是为操作安全设置的快速开关。
本实用新型的优越性在于操作安全方便,可适用范围广,焊接效率高。下面通过附图详加说明。
附图1、防回火装置在焊炬咀部与阀间的燃气通道上的燃气焊炬。
附图2、防回火装置在中部主体内阀前端的燃气焊炬。
如图1,本实用新型具有燃气接头(1)、燃气通道(5)、手柄(2)及阀(3)和焊咀部(4),特征是:防回火装置安装在阀(3)和焊咀部(4)间。防回火装置由止火管(6)、止火管座(7)组成。将防回火装置装在外壳套管(14)内,由密封圈(8,15,16,17,18)、止火管压紧螺母(9)、接头螺母(10)将其与燃气通道(5)连接固定。如图2,有燃气接头(1)、燃气通道(5)、手柄(2)及阀(3)和焊咀部(4),特征是:在手柄(2)处装一手柄阀(11),防回火装置在有阀(3)和燃气通道(5)的中部主体(13)的阀(3)的前端,防回火装置套入中部主体内由止火管压紧螺母(12)、连接螺母(10)、密封圈(8、9、14、15、16)连接固定。

Claims (4)

1、一种燃气焊炬,具有燃气接头、手柄、通道及阀和焊部,其特征在于:防回火装置装在阀的前端。
2、由权利要求1所述的燃气焊炬,其特征在于:防回火装置由止火管及其前端的止火管座组成。
3、由权利要求1、2所述的燃气焊炬,其特征在于:防回火装置可套在外壳套管内通过连接件、密封圈与阀前端的燃气通道连接固定。
4、由权利要求1、2所述的燃气焊炬,其特征在于:手柄与燃气接头端可装手柄阀,防回火装置可装在手柄前端的有阀和燃气通道的中部主体内的阀前端,由连接件、密封圈连接固定。
