Description of drawings

Fig. 1 is a schematic structural diagram of a manual pressure vessel hydraulic test system of the present invention. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. the

As shown in Figure 1, a manual pressure vessel hydraulic test system includes a water inlet throttle valve 1, a safety valve 2, a water outlet throttle valve 3, a pressure gauge 4, a pressure gauge 5, a head 6, an inlet and drain valve Plate 7, manual pressure test pump 8, head 9, pressure test blind plate 10 and ball valve 11. A sealing head 6 and a sealing head 9 are arranged on both sides of the pressure vessel body 12 respectively, and the sealing head 6 and the sealing head 9 are used to seal the pressure vessel body 12 . the

The bottom of the pressure vessel body 12 is connected with an inlet and drain blind plate 7 through a pipeline, and the inlet and drain blind plate 7 is connected with an external water inlet device through an external pipeline, and a ball valve 11 is arranged on the external pipeline. A pressure test blind plate 10 is connected through a pipeline, and the pressure test blind plate 10 is connected with a manual pressure test pump 8 through a side pipeline. The top of 10 is provided with an upper pipeline, and a pressure gauge 4, a pressure gauge 5 and a water outlet throttle valve 3 are arranged on the upper pipeline. A safety valve 2 is installed at the top of the top pipeline. the

When carrying out the pressure test on the pressure vessel body 12, first connect the pressure vessel body 12 with the inlet and drain blind plate 7, the manual pressure test pump 8 and the pressure test blind plate 10 through pipelines, then open the ball valve 11, and the inlet and drain blind plate 7. Fill the pressure vessel body 12 with water and exhaust, and the discharged gas is discharged from the water outlet throttle valve 3. When the gas is exhausted, close the ball valve 11 and the water outlet throttle valve 3. Then open the water inlet throttle valve 1 and pressurize the pressure vessel body 12 with the manual pressure test pump 8, stop pressurization after reaching the predetermined test pressure, close the water inlet throttle valve 1 to maintain pressure.
