Come, it is achieved osmotic fluid and extraneous sealing.
2, functional part
1) seal rubber sleeve 1
Such as Fig. 1,2,3,4, seal rubber sleeve 1 is a kind of approximation cross shape being centrosymmetric being made up of ethylene propylene diene rubber
Seal rubber sleeve 1 (is divided into two pieces, left and right along center vertical line, then You Kuaiyan center turns clockwise 180 i.e. and left piece of weight by housing
Close), thickness of shell about 2mm, opening up and down；

Its position and annexation be:
2 deformed capsule 1-1 are respectively placed in the internal shear displacemant district, the left and right sides of seal rubber sleeve 1, and 2 pieces of deformable closure 1-2 are respectively
It is close to 2 deformed capsule 1-1.
* deformed capsule 1-1
Deformed capsule 1-1 is a kind of to be made the square utricule with fluid-infusing port by ethylene propylene diene rubber, can be with interior external pressure
The deformation of power difference generation certain volume, soars position for rock sample 2 shear displacemant, thus broken when avoiding rock sample 2 that shear displacemant occurs
Bad seal rubber sleeve 1.
* deformable closure 1-2
Deformable closure 1-2 is the metallic plate that a kind of size made of aluminum matches with deformed capsule 1-1, is clipped in deformed capsule 1-
Between 1 and rock sample 2, and can move, it is to avoid deformed capsule 1-1 directly contacts with rock sample 2 and destroys.
2) rock sample 2
Rock sample 2 is rock sample to be tested, is typically the cube of certain size.
3) shear plate 3
Shear plate 3 is a kind of stainless steel, has certain size and the cuboid with fluid passage 3-1；
Its function is that rock sample 2 applies shearing force, and by its fluid passage 3-1, rock sample 2 can be injected fluid.
4) normal direction pressing plate 4
4 one kinds of stainless steels of normal direction pressing plate, there is the cuboid of certain size；
Its function is that rock sample 2 is applied normal stress.
5) confined pressure follows the tracks of pump 5
It is that one can automatically adjust output pressure according to confined pressure room 7 internal pressure value and keep consistent with confined pressure that confined pressure follows the tracks of pump 5
Compression pump；
In its function is to maintain deformed capsule 1-1, pressure is consistent with confined pressure so that rock sample 2 shear displacemant change crimp capsule
In not resulting in deformed capsule 1-1 when 1-1 diminishes, pressure raises and causes seal rubber sleeve 1 to deform.
6) computer 6
Computer 6 is a kind of conventional computer；
Its function is confined pressure to be monitored and controlled follow the tracks of the pressure of pump 5, it is simple to realize deformed capsule 1-1 and confined pressure room 7 internal pressure
Keep consistent.
7) confined pressure room 7
Confined pressure room 7 is the stress loading test chamber of a kind of true triaxial test machine；
Its function is to apply the stress of X, Y and Z-direction, X and Y-direction to apply stress for rock sample 2 by piston, and Z-direction is by enclosing
Pressure chamber internal high pressure hydraulic oil applies.
3, operation principle
During shearing test, confined pressure room 7 internal pressure is consistently higher than the pressure injecting fluid, thus inside, confined pressure room 7 is pressed
Power can compress seal rubber sleeve 1, it is to avoid the fluid of injection scurries into confined pressure room 1 and by two side channelling of rock sample 2, finally realizes
Well sealing.
Rock sample 2 is carried out in shear history by confined pressure room 7, follows the tracks of pump 5 by confined pressure and makes deformed capsule 1-1 and confined pressure room 7
Internal pressure is always consistent；Along with the increase of the shearing force to rock sample 2, rock sample 2 can occur shear displacemant, and then by becoming
Deformed capsule 1-1 is extruded by shape dividing plate 1-2, makes deformed capsule 1-1 internal pressure increase, deformed capsule 1-1 internal pressure
After increasing, confined pressure is followed the tracks of pump 5 and deformed capsule 1-1 internal liquid can be got rid of a part and make deformed capsule 1-1 and confined pressure room 7
Internal pressure is always consistent, and then makes the volume of deformed capsule 1-1 diminish；Along with the carrying out of shear history, a upper process
Constantly repeating, terminating until shearing.
Deformable closure 1-2 avoid damage to after rock sample 2 on coarse corner seal rubber sleeve 1 and deformed capsule 1-1 are directly connect
Touch and destroy.
