Abstract
The utility model discloses a rock mechanics three-axis testing high-pressure kettle, is designed for solving the problems of high machining cost, relatively large size and the like of equipment. A kettle body of the high-pressure kettle is arranged in a three-axis rack; a kettle cover with a central piston hole is connected and arranged at the top end of the kettle body, and a bearing base sealed by an annular sealing ring is connected to the bottom end of the kettle body; an axial loading piston sealed by an annular sealing ring is arranged in the kettle body, and a balance communication tube for communicating an upper space and a lower space of the piston is arranged on the sidewall of the kettle body; a piston rod on the upper part of the axial loading piston penetrates through the central piston hole in the kettle cover and sealed by the annular sealing ring, and the top end of the piston rod is connected with the top surface of the three-axis rack. The high-pressure kettle realizes the pressure self-balance by the balance communication tube arranged on the kettle body, and thus the pressure born by the three-axis rack is reduced, an application of the three-axis rack can be relatively economic, relatively simple and relatively convenient, and relatively safe, the manufacturing cost spent on the high-pressure kettle is greatly saved, and a three-axis compression experiment is facilitated.
Description
Technical field
The utility model relates to a kind of rock mechanics three axle testing high voltage stills, belongs to test facility technical field.
Background technology
Conventional rock mechanics three axle testing high voltage stills carry out rock sample loading experiment by upper and lower flexible bearing base.Loading in the process of confined pressure, because the upward pressure of confined pressure generation is all applied in three axle frames, so only possess, enough the frame of powerful drag could this pressure of balance.Therefore, the manufacture scale of high strength frame is inevitable larger, puts inconvenience, and processing cost is also higher.
Summary of the invention
The purpose of this utility model is to provide a kind of rock mechanics three axle testing high voltage stills, to solve the problems such as equipment processing cost height and volume are larger.
Concrete technology contents of the present utility model is as follows:
This autoclave kettle is located in three axle frames; Kettle top is connected with the kettle cover in center piston hole, and bottom connects the bearing base being sealed by grommet type seals; In kettle, be provided with the axial loading piston being sealed by grommet type seals, kettle sidewall is provided with the balance communicating pipe that is communicated with piston upper and lower space; Axially load the piston rod on piston top through center piston hole on kettle cover, that sealed by grommet type seals, piston rod top connects three axle frame end faces.
This autoclave is realized pressure self-balancing by the balance communicating pipe being located on kettle, thereby can alleviate the pressure that three axle frames are carried, the application that makes three axle frames more economically, easy and safety, the manufacturing cost that can significantly save autoclave, facilitates triaxial compression test.
Brief description of the drawings
Fig. 1 is traditional rock mechanics three axle testing high voltage still structural representations.
Fig. 2 is rock mechanics three axle testing high voltage still structural representations.
Embodiment
Embodiment:
With reference to Fig. 2, embodiment of the present utility model is further illustrated:
This autoclave mainly comprises three axle frames 1, pin 2, kettle cover 3, axially loads piston 4, kettle 5, grommet type seals 6, rock sample 7, bearing base 8 and balance communicating pipe 9;
Kettle 5 is located in three axle frames 1; Kettle 5 tops are connected with the kettle cover 3 in center piston hole by pin 2, bottom connects the bearing base 8 being sealed by grommet type seals 6; In kettle 5, be provided with the axial loading piston 4 being sealed by grommet type seals 6, kettle 5 sidewalls are provided with the balance communicating pipe 9 that is communicated with piston upper and lower space; Axially load the piston rod on piston 4 tops through center piston hole on kettle cover 3, that sealed by grommet type seals 6, piston rod top connects three axle frame 1 end faces.
When test, rock sample 7 is placed between axial loading piston 4 and bearing base 8, moves down piston and load, meanwhile, carry out confined pressure loading to being filled with highly pressurised liquid in kettle 5, now, piston is realized the self-equilibrating of its upper and lower pressure by balance communicating pipe 9.
