The invention provides an independent depressurization mechanism, in particular to an independent depressurization mechanism, wherein after a deck plate 32 ascends, a follower plate 35 and a driving plate 38 are matched with a flat pushing fluid, the resistance is increased, the folding plate frame 27 is driven by the ascending of the deck plate 32, a central shaft 43 is controlled by the folding plate frame 27, a middle cylinder 42 ascends, a second plate 31 reciprocates and translationally pushes the bottom end of a lever pressing frame 28, the top end of the lever pressing frame 28 pushes the first plate 26 to translate, the lever pressing frame 28 swings, a misplacement sliding occurs between a concave sliding plate 40 and an inner sliding square column 41, thus the lever function of the lever pressing frame 28 is stably realized, after the middle cylinder 42 ascends, the reset motion pressure of the second plate 31 is unchanged, the reset motion pressure of the first plate 26 is increased, the first plate 26 drives a transverse frame 36 to further control the driving plate 38, then the follower plate 35 to move through a unit L-shaped plate 37, the driving plate 38 and the follower plate 35 synchronously push the pressure of the flat pushing fluid is increased, if the lever pressing mechanism of the lever pressing frame 5 is not needed, the push-pull shaft 6 directly acts on the piston, once the amount of fluid pushed by the piston increases, the push-pull force is increased, and the reset motion of the second plate 31 is transmitted to the outside through the lever driving mechanism through the opposite to the outside, and the outside of the drive mechanism is externally connected with the drive mechanism, and the drive mechanism is protected.
The control member 7 and the middle cylinder 42 are lifted synchronously, when the swing amplitude of the second plate 31 is unchanged after the middle cylinder 42 is lifted, the swing amplitude of the first plate 26 is reduced, namely the distance for causing the reciprocating flat pushing of the piston is reduced, although the conveying speed of the flow pump is reduced, after the control member 7 is lifted, the space of the working cavity is increased, the liquid flow rate is still lifted, because the horizontal length of the inner box 2 is enough, the shelf plate 32 is lifted for a short distance, the space of the working cavity is obviously increased, the influence of the space increase on the flow is larger than the influence of the reduction of the swing distance of the piston, and finally the liquid flow rate of the flow pump is increased.
The external gear ring 16 drives the clockwork spring 17 to further control the design of the top disc 18, flexible adjustment is achieved, the deformation expansion or contraction process of the control piece 7 can be carried out in the working process of the fluid pump, the displacement of the central pressure point of the lever can also be achieved in the continuous swinging process of the top disc 18, and therefore the process pump can adjust and change the space of the internal working cavity of the inner box 2 in real time according to requirements in the process of conveying liquid, and further the fluid conveying speed is changed.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
