Detailed Description
A frock that is used for nuclear power station boron notes case hydraulic test to suppress, includes into water frock 11, exhaust frock 12, and into water frock 11, exhaust frock 12 all with boron notes case switch-on, and hydraulic test pump 13 is through high-pressure hose 14 and the frock 11 switch-on that intakes
The water inlet tool 11 is shown in figure 1 and comprises a flange connecting piece 1, a buffer tank 2 and a temperature indicator table 3
The flange connecting piece 1 is a standard piece, is matched with a pipeline and is used for connecting a hydraulic test pump 13.
The buffer tank 2 is a simple direct contact type buffer tank and is used for buffering pressure fluctuation in the boosting period of the hydrostatic test, so that three pressure platforms of the hydrostatic test are stable in transition.
The temperature indicator 3 is connected to the buffer tank 2 and used for measuring the water temperature in the hydraulic test device and ensuring that the water temperature in the hydraulic test device is in a specified range.
