过去,我们常用的乙炔发生器是由可升降的电石浸沉式乙炔容器倒扣在水桶内作成的。这种乙炔发生器还不很完善,除乙炔容器可能爆炸以外,过去也曾发生过水封保险壶本身的爆炸事故。改进后的乙炔发生器,其外形尺寸、作用原理与原来的大体相同,仅把顶部防爆部分作成可开启式的(图4)。但这一改进对乙炔发生器的安全使用起了很大作用。它有以下几个特点。一,当乙炔容器爆炸
In the past, our commonly used acetylene generators were built by flipping calcium carbide impregnated acetylene containers upside down in buckets. This acetylene generator is not yet perfect, except that the acetylene vessel may explode. In the past, there have been explosion accidents in the water-sealable safety vessel itself. The improved acetylene generator has the same dimensions and principle of action as the original one, and only the top explosion-proof part is made openable (Figure 4). However, this improvement has played a significant role in the safe use of the acetylene generator. It has the following features. One, when the acetylene container explodes
