我们车间曾发生数次乙炔发生器浮桶的回火爆炸事故。为了防止爆炸,达到安全生产的目的,研制了三种乙炔回火防止器,现介绍如下。乙炔回火防止器是一种防止乙炔、氧气混合气体由于某种原因从焊、割炬燃烧而引起乙炔发生器爆炸的安全装置我车间研制的乙炔回火防止器属于干式,它具有安全可靠,使用方便,体积小,制造简单等优点。一、结构与作用原理乙炔回火防止器的设计,用单向逆止阀原理,阀片采用碗形周边槽的结构,阀体与阀片接触面呈元形刀口状。经过研磨达到密封精度。装配时调整
There have been several tempering explosion of acetylene generator floats in our workshop. In order to prevent explosions, to achieve the purpose of production safety, developed three kinds of acetylene tempering prevention device, are described below. Acetylene tempering prevention device is a kind of prevent acetylene, oxygen gas mixture for some reason from the welding torch burning caused acetylene generator explosion safety device I developed acetylene tempering preventer is dry, it is safe and reliable , Easy to use, small size, easy to manufacture and so on. First, the structure and role of acetylene tempering prevent the design, with one-way check valve principle, the valve plate bowl-shaped peripheral groove structure, the valve body and the valve surface was a meta-knife-like. After grinding to seal accuracy. Adjust when assembling
