CN108800133A 改进的涡旋燃烧空气燃料焊炬 无效 - 驳回

改进的涡旋燃烧空气燃料焊炬
摘要：
焊炬(100)被提供有焊炬本体(103)、嘴孔口(107)结构以及管(101)。所述焊炬本体(103)具有上游腔(110)、混合腔(113)以及管连接部分(102)，所述混合腔(113)具有通过混合腔的侧壁的多个圆锥孔(104)来允许空气流进入混合腔。所述嘴孔口(107)结构被插入到上游腔(110)并且具有通过嘴孔口结构的中央的孔。所述孔具有第一直径并且将燃料引导到混合腔(113)。所述管连接部分(102)将所述燃料/空气混合物从所述混合腔(113)输送到所述管(101)来在所述管的出口处建立火焰。对于乙炔作为燃料而言，孔的所述第一直径与所述管(101)的所述内径(iD)的比例在5％至7％的范围内，或者对于丙烷或丙烯作为燃料而言，所述比例在2％至3％的范围内。
摘要（英）：

A torch (100) is provided with a torch body (103), a tip orifice (107) structure, and a tube (101). The torch body (103) has an upstream cavity (110), a mixture cavity (113) with a plurality of conical bores (104) through its sidewall to permit a flow of air into it, and a tube connection portion (102). The tip orifice (107) structure is inserted into upstream cavity (110) and has a bore through its centre. The bore has a first diameter and directs a fuel to the mixture cavity (113). The tube connection portion (102) transports the fuel/air mixture from the mixture cavity (113) to the tube (101) to build a flame at the tube's exit. The ratio of the first diameter of bore and the inner diameter (iD) of the tube (101) is in the range of 5 to 7% for acetylene as fuel, or in the range of 2 to3% for either propane or propylene as fuel.
