Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description is made in detail with reference to the accompanying drawings. It is to be understood that the description herein is intended to illustrate the invention and is not intended to limit the invention.

As shown in figure 1, the device comprises a shell 1 and a piston 2 arranged at one end of the shell 1, wherein an intermediate joint 5 is arranged at the other end of the shell 1, and a shell 6 is arranged outside the intermediate joint 5. The piston 2 comprises a first piston body 7 and a second piston body 8, the diameter D of the first piston body 7₁Is smaller than the diameter D of the second piston body 8₂Correspondingly, a first inner cavity 9 and a second inner cavity 10 are arranged on the inner side of the shell 1, the first inner cavity 9 is a high-pressure cavity, and the diameter d of the first inner cavity 9₁Is smaller than the diameter d of the second lumen 10₂The first piston body 7 is connected with the first inner cavity 9 in a sealing mode through a sealing ring, and the second piston body 8 is connected with the second inner cavity 10 in a sealing mode through a sealing ring.

The middle joint is provided with an oil hole 11 and a liquid channel 12, the oil hole 11 and the liquid channel 12 are both communicated with the first inner cavity 9, the oil hole 11 is sealed through an oil plug 4, and the liquid channel 12 is sealed through a sealing plug 5. According to the formula

It can be seen that when the pressures are equal, the pressure ratio is equal to the inverse of the area, so that the ratio of the areas of the cross-sections of the first and second piston bodies 7, 8 determines the proportion of the pressure increase.

In use, the piston 2 is first mounted to the housing 1, the intermediate fitting 3 is then mounted to the other end of the housing 1, the sealing plug 5 to be tested is then mounted to the intermediate fitting 3, and the housing 6 is then mounted to the other end of the intermediate fitting 3. After the high-pressure cavity is filled with silicon oil through the oil filling nozzle, the oil hole 11 is firmly blocked by the oil plug 4. The whole device is placed into a low-pressure cavity 13 of the existing pressurizing device, the low-pressure cavity 13 is heated and pressurized, and the high-pressure cavity is further pressurized by means of the area difference between the end faces of the first piston body 7 and the second piston body 8. The cross-sectional area ratio of the second piston body 8 to the first piston body 7 is 2:1 in this embodiment, whereby it is obtained that when the pressure in the low-pressure chamber 13 rises to 80MPa, the pressure in the high-pressure chamber will rise to 160MPa for pressure equalization. Meanwhile, in a high-temperature environment, the silicone oil in the high-pressure cavity expands, so that a certain safety distance is reserved at the piston end of the shell 1 according to the expansion coefficient of the silicone oil along with the temperature, and in the embodiment, the length L of the second inner cavity₂At least the length L of the first inner cavity₁1/5, and a screw plug is arranged on the outer side of the piston to be in threaded connection with the shell 1 in order to further prevent the piston from being expanded and removed by the silicon oil.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
