Description of drawings

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

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

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 blind 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 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 the tank 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.

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. According to the requirements of pressure vessel safety and supervision standards, the test device is equipped with pressure gauge 4 and pressure gauge 5. The two gauges are installed at the same height from the ground, and a safety valve 2 is installed on the top of the pressure test blind plate 10. , so that when the operating pressure exceeds the pressure test pressure during the test, the safety valve 2 can be automatically detonated to relieve the pressure in the container and prevent damage to the container due to misoperation. During the test, the pressure can be adjusted or the pressure can be relieved through the water outlet throttle valve 3. After the test is completed, the ball valve 11 can be opened to drain the water in the pressure vessel body 12 through the inlet and drain blind plate 7, and the pressure test is completed. .

In summary, the manual pressure vessel hydrostatic test system of the present invention is simple in structure, easy to operate, safe and reliable, suitable for hydrostatic test operations on various pressure vessels, and especially suitable for vocational colleges to test equipment for students Pressure test operation vocational skills training.
