Movable pipeline built-in cavity regulating and controlling system

Abstract

The invention relates to a movable pipeline built-in cavity regulating and controlling system, and belongs to the bionic field of hydraulic machinery. The invention aims to solve the problems that anexisting hydraulic pipeline is single in function, the pressure and the flow of transmission medium cannot be cleaned, and the load working efficiency, the conveying stability and the conveying efficiency are influenced by the pressure and the flow of the transmission medium are solved. The system comprises four groups of energy storage and unloading parts, a functional valve part, a valve body movement adjusting part, a battery and a main controller, wherein the energy storage and unloading parts are distributed on a hydraulic pipeline in four points; the functional valve part is arranged inthe hydraulic pipeline, the functional valve part comprises a pressurizing valve, a pressure reducing valve, a hydraulic control one-way valve, four first pressure sensors and four first flow sensors,the pressurizing valve, the pressure reducing valve and the hydraulic control one-way valve are sequentially connected in series in the flowing direction of fluid in the pipeline, and the four firstpressure sensors and the four first main controllers are distributed in eight points at the two ends of the pressurizing valve, the pressure reducing valve and the hydraulic control one-way valve; thevalve body movement adjusting part is used for driving the functional valve part to move along the hydraulic pipeline; and the battery is connected with power elements in the pipeline for supplying power, and the main controller controls the movement of each power element through information collected by the pressure sensors and the flow sensors.

Description

technical field [0001] The invention belongs to the field of hydraulic mechanical bionics, and in particular relates to a mobile pipeline built-in sub-cavity control system. Background technique [0002] There are two types of traditional hydraulic pipes: hard pipes and flexible pipes. Hard pipes are all metal materials, including seamless steel pipes, seamed steel pipes and copper pipes. The hoses are mostly selected according to the system pressure, including oil-resistant rubber hoses, oil-resistant plastic hoses and nylon hoses. [0003] Traditional hydraulic pipelines have a single function, and the fluid pressure and flow inside the pipeline cannot be regulated. When the flow and pressure of the fluid medium inside the pipeline change suddenly, it will have a great impact on the load machinery and even lead to mechanical failure or accidents; in addition , the substances adhering to the inside of the pipeline cannot be effectively cleaned. When the medium moves betwe...
