不同截面管子的连接方法

多数管通系统是由圆管制成的,这固然有不少优点,但是,当连接管道截面的大小、形状不同,或管道有弯向时,会给制作工艺带来麻烦。同时,圆管比起板材价格较昂贵,假如用板材制作,还可制成不同截面的多边形管子。在不同截面管子的连接方法上,文中还阐述了一简单的函数关系式:γ=f(x),可避免用非回曲线或透视仿射等方法,从而提高了作图的准确性。

The Method of Connecting Pipes with Different Sections

Most piping systems are fabricated from cylindrical pipes.They have many advantages.But difficulties exist if the sectional sizes or shapes of two pipes to be connected are different or they have bends. A cylindrical pipe is more expensive than a plate.It is more costly if its section is polygonal. In this paper asimple function y=f(x) is used for the calculation of connecting two pipes with different sizes of sections.It does not require the calculation of a non-circular curve or perspective correspondence and thus improves drafting accuracy.
