Flow testing device and liquid circulation capability detecting method utilizing same

The invention discloses a flow testing device and a liquid circulation capability detecting method utilizing the same. The device comprises a body (1), the body (1) comprises a liquid inlet valve (5),a liquid discharge valve (8), an air inlet valve (3), a safety valve (12), an exhaust valve (10), a blow-down valve (7), a visual liquid level meter (6), a first pressure gauge (11) and a second pressure gauge (21). The air inlet valve (5) is communicated with a pressure regulating valve (2) through an air pipe (13), the liquid inlet valve (5) is connected with the liquid inlet pipe (4), and theliquid discharge valve (8) is communicated with a flow testing valve (9) through a liquid discharge pipe (14). The pressure of the flow testing device can be constant, and the valve circulation capability measuring precision is improved. 本发明公开了种流量试验装置及利用该装置的液体流通能力检测方法，包括本体（1），本体（1）包括进液阀（5）、排液阀（8）、进气阀（3）、安全阀（12）、排气阀（10）、排污阀（7）、可视液位计（6）、第压力表（11）、第二压力表（21），进气阀（5）通过空气管（13）与调压阀（2）连通，进液阀（5）与进液管（4）相连，排液阀（8）通过排液管（14）与流量试验阀（9）连通。本发
