Abstract

A graduated disc and an indicating needle are installed in a shell of a simple pipeline kinemometer, and the indicating needle is movably connected with the shell through a bearing, and a spring is installed between the indicating needle and the inner wall of the shell. The simple pipeline kinemometer has low manufacture cost, small volume and big reliability, can satisfy demands of certain measurement precision, is applicable to being installed on a pipeline in a valve sunk well, and can be used to observe the current velocity of a mounting point very conveniently. Surely, the flow capacity of one point can be known through comprehending the current velocity of the point, and the pipe diameter of the point is definite.
在简易管道流速计的壳体内装有刻度盘和指针,指针通过轴承与壳体动连。在指针与壳体内壁之间装有弹簧。本实用新型造价低、体积小、可靠性大,可以满足一定测量精度的需要。适用于阀门沉井中管道上的安装。可以非常方便地观测安装点的流速,当然,知道了该点的流速,也就知道了该点流量——该点的管径是确定的。
