Description

The invention relates to a testing technique and can be used in hydrotesting hollow body parts.

The purpose of the invention is to reduce power consumption by using the force of gravity of the test piece to supply the test medium, as well as to provide re-testing.

The drawing shows a diagram of the device for implementing the method of supplying and draining the test medium during hydrotesting hollow parts

The device for hydrotesting part 1 contains a variable volume tank 2 with a movable top cover — table 3. The tank 2 is partially filled with test medium 4 and connected to the part cavity

1pipeline 5 with pressure regulator 6 A vessel 7 is provided for draining the fluid. It is connected to part I and a tank.

2 through the overflow valve 8. On line 5, at the outlet of the tank 2, a valve 9 is installed.

The method is carried out as follows.

Test piece 1 is placed on a sliding cover table 3 behind a sealed container 2 with a test medium 4. Under the force of gravity of the part 1, the cover table 3 is lowered, compressing the air in the gas cavity of the container 2. Connecting part 1 to the pipeline 5 The pressure regulator 6 is adjusted to the required test pressure of part 1. Open fan 9, fill part 1 with test medium,

simultaneously releasing air from it. At the end of the filling, the part 1 is sealed, after which an overpressure is established in it, equal to the pressure of the setting of the pressure regulator 6. The test is carried out, after which the test medium is drained from part 1. If retesting is necessary, the drainage is carried out through the intermediate vessel 7 into the container 2. To do this, close the valve 9 to supply the test medium 4. Open the drainage of water from part 1 to vessel 7 and drain the part 1. After draining, remove part 1 from the table top 3. The volume of the container 2 is restored to the original, and the pressure is restored to atmospheric, the cover-table 3 returns to its original state. The overflow valve 8 is opened and the test medium is drained from the vessel 7 into the container 2. This completes the cycle of one test.

The invention makes it possible to exclude from the composition of the stand means for supplying the test medium, and from the test technology, the operation of supplying the medium, thereby obtaining energy and material cost savings.

Claims (2)

1. The method of supplying and discharging the test medium during hydrotesting hollow body parts, including creating a gas pressure in the container cavity with a test medium connected to the part cavity, and reducing the pressure in the container cavity, characterized in that reduce energy consumption by using the force of gravity of the test piece to supply the medium; as a container with the test medium, use a variable volume capacity with a movable upper the lid, and the pressure in it is created by mounting the part on the top cover of the container. 2. A method according to claim 1, characterized in that, in order to provide repeated tests, the pressure in the cavity of the tank with the test medium is reduced by draining the test medium from the part into the intermediate vessel and removing parts from the top cover of the tank.
