【技术实现步骤摘要】
本技术涉及一种减压阀,尤其是一种将高压气体直接转变为低压气体的横式减压阀,该减压阀可用于各种减压供气场合,特别适用于加氧助燃的焊接工具的供气。
技术介绍
一般减压阀和气瓶瓶头阀均是分开制造的,使用时将它们组装在一起而成一高压气体转变为低压气体的减压阀。这样的减压阀装配麻烦、体积大、使用不便,以及密封性能常常得不到保证。目前,在市场上,有一种类似横阀的减压阀,其出气嘴方向均为垂直方向,使用时供输气的连接管很难准确定位,特别在插入角度不适合时,造成连接管难以拔出,使用十分不方便。
技术实现思路
本技术的目的是为了克服上述现有技术的缺陷而提供一种将减压阀和气瓶瓶头阀紧凑而合理地整合成一体,以使高压气体可直接转变为低压气体的横式减压阀,而且,此减压阀可直接装在气瓶上。实现上述目的的方案是提供一种直接将高压气体转变为低压气体的横式减压阀,它包括带有气瓶接头的阀体、活门、阀杆、手柄、出气嘴、用以出气嘴接装的第一帽盖,其中,所述阀体具有一中央阀室以及与中央阀室连通的一带内螺纹的进气孔、一出气孔和一通向气瓶的气瓶连孔,所述出气孔内设有出气侧阀室,其端口所在端面上设有一环形槽,所述环形槽将出气孔外壁面分成内、外环壁,所述活门包括一第一活门和一第二活门,第一活门为圆柱形的,安装在中央阀室内,其上端与阀杆的下端连接,下端与气瓶连孔相面对,以在中央阀室的关闭状态封住通向气瓶的气瓶连孔,所述第二活门也为圆柱形的,安装在出气侧阀室内,以在出气侧阀室的关闭状态封住中央阀室通向出气嘴的出气孔的出气口,减压阀还包括一第二盖帽、一双活塞滑块、一弹簧和一进出气口堵塞,其中,第二盖帽在其帽顶上设有 ...
