Embodiment 1

[0051] Such as figure 2 , image 3 As shown, this embodiment discloses a device for testing the closing performance of a flap valve, including a valve seat fixing mechanism 6 for fixing the valve seat, a core barrel driving mechanism 5 for driving the core barrel up and down, and the above-mentioned rotary experimental platform.

[0052] The platform 4 is placed in the box body 100, and the box body 100 has an observation window. Placing the platform 4 in the box 100 has three functions: first, to realize the protection function. When the valve clack is closed, the air pressure is used to determine its pretightening force. second, to realize the modular concealment of the control mechanism, and to package each pneumatic and electric device in the box body 100 to achieve a clean and functional modular effect; third, the test bench not only has experimental functions, but also has certain functions. The valve seat closing action display function can realize the dynamic displa...

Embodiment 2

[0083] In this embodiment, the first base 41 and the second base 42 are disc-shaped. The first base 41 is arranged parallel to the second base 42 . The two rotating shafts 44 are radially disposed on opposite sides of the first base 41 .

Abstract

The invention relates to a rotary experiment platform and a flap valve closing performance testing device, and the platform comprises a platform which comprises a first pedestal, a second pedestal, a first rotation driving mechanism, and a second rotation driving mechanism. The first rotation driving mechanism is connected with the first base and used for driving the first base and the second base to rotate in the first direction. The second base is rotationally connected with the first base, and the second rotation driving mechanism is connected with the second base and used for driving the second base to rotate relative to the first base in the second direction; and the second direction is perpendicular to the first direction. The inclination of the platform can be adjusted, and the closing conditions of the flap valve in different drilling directions can be tested; and the second base can rotate relative to the first base, so that the valve clack and the valve seat integrally rotate around the valve seat in the axial direction, and tests of the valve clack at different inclination angles and different placement positions can be achieved under the combined action of the first base and the second base.

Description

technical field [0001] The invention relates to the technical field of a pressure-holding coring experiment device, in particular to a rotary experiment platform and a flap valve closing performance test device. Background technique [0002] The physical, mechanical, chemical and biological properties of deep rocks are closely related to their in-situ environmental conditions. The loss of the in-situ environment during the coring process will lead to irreversible distortion of the physical, chemical and mechanical properties of the core. The core and key of the research is how to Obtain in-situ cores under deep environmental conditions, and perform real-time loading tests and analysis under in-situ fidelity. [0003] The current in-situ fidelity coring device uses a drilling tool to drill the core and stores the core in the fidelity chamber, and then uses the fidelity chamber pressure maintaining control device to maintain the pressure and seal the sample. [0004] The pres...
