打火机恒流出气阀
本技术涉及一种打火机出气阀,尤其是一种恒流出气阀。
技术介绍
现有的打火机出气阀,包括阀壳、阀座和出气针,所述阀壳的下端安装在阀座上,所述阀座内腔设有定位凸尖,所述出气针的底部插装T型密封塞,所述T型密封塞顶在所述定位凸尖,所述出气针下部位于所述阀座的内腔,所述出气针的中部外壁设有支撑凸环,出气针中上部外壁套装弹簧,所述弹簧的下端位于所述支撑凸环上,所述阀壳的内腔上部与出气针之间设有密封圈,所述弹簧的上部顶触在所述密封圈上。通过拉伸组件将出气针向上拉,使得T型密封塞与所述定位凸尖分离,实现气体通道贯通;拉伸组件复位,在弹簧的作用下,所述T型密封塞顶紧在所述定位凸尖上。在阀座下部的进气通道上布置恒流微孔膜,该恒流微孔膜通过塑料套进行定位,所述塑料套插接在所述阀座下部的内腔且顶触所述恒流微孔膜。存在的技术缺陷是:由于塑料套与阀座下部的内腔之间为插接,相互之间过盈配合,装配时需要较大的插接力才能实现定位;再者,比如在装配和运输过程等情况存在较大振动,插接定位的方式容易收到外界振动而造成松动,可靠性较差,影响恒流微孔膜的定位,从而影响出气阀的质量。
技术实现思路
为了克服已有打火机出气阀的恒流微孔膜容易松动、可靠性较差的不足,本技术提供了一种有效避免恒流微孔膜松动、可靠性良好的打火机恒流出气阀。本技术解决其技术问题所采用的技术方案是:一种打火机恒流出气阀,包括阀壳、出气针和恒流微孔膜,所述出气针位于所述阀壳的内腔,所述出气针中部开有出气孔,所述出气针的下部外壁设有支撑凸环,出气针中上部外壁套装弹簧,所述弹簧的下端位于所述支撑凸环上,所述阀壳的内壁上部 ...
