Embodiment Construction
[0041] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0042] Such as figure 1 A pressure regulation and pressure maintenance system for pressure maintenance and transfer of deep-sea sediments shown includes a low-pressure pump 214, a high-pressure pump 213, a one-way valve, a filter, a pressure sensor, a stop valve, an accumulator 206, a proportional overflow valve 208 and The controller 301 can be used to realize constant pressure inside the pressure maintaining transfer device; the pressure maintaining transfer device includes a sampler 101, a cutting device 102, a ball valve I 103, a ball valve II 104, a clamping device 105, and a manipulation chamber 106 connected in sequence, And the connection between the sampler 101 and the cutting device 102 , and between the ball valve I 103 and the ball valve II 104 are communicated by means of connectors.
[0043] In the pressure regulating and maintain...
