Description

一种新型真空弯头
技术领域
本实用新型涉及管道技术领域,尤其是一种新型真空弯头。
背景技术
传统管件其大小管道不同口径直径的过渡,往往需要将大口径管件和小口径管道焊接而成,不仅常常费时费力,而且往往容易造成断裂,使管道失效。
发明内容
为解决上述问题,本实用新型提供了一种新型真空弯头,所述一种新型真空弯头,其特征在于,包括:空心管1、外管壁2、上管层头3、管内层4、下管层头5,所述一种新型真空弯头,在空心管1上设有上管层头3,其空心管1和上管层头3是同一材料一次拉伸成型。 
本实用新型效果:1. 一次拉伸成型,无需焊接;2.方便操作;3.提高管道压力,防止断裂。
附图说明
  图1为本实用新型示意图;
  其中:空心管1、外管壁2、上管层头3、管内层4、下管层头5。
具体实施方式
   如图所示,所述一种新型真空弯头,在空心管1上设有上管层头3,其空心管1和上管层头3是同一材料,在拉伸模具设备上一次拉伸成型。
