Novel fluid pressure regulation apparatus and fluid pressure regulation method thereof

Abstract

The invention relates to a novel fluid pressure regulation apparatus and a fluid pressure regulation method thereof. The apparatus comprises pressure regulation elements and vacuum generators, wherein a pipeline of an outlet of each vacuum generator is provided with a feedback loop, each feedback loop feeds fluid pressure of the outlet of the corresponding vacuum generator back to the corresponding pressure regulation element, and each feedback loop controls the corresponding pressure regulation element; and each vacuum generator comprises a supply port, the outlet and an absorption port, the output end of each pressure regulation element communicates with the supply port of the corresponding vacuum generator through the pipeline, the outlet of each vacuum generator communicates with the corresponding pressure regulation element through the corresponding feedback loop, and each absorption port communicates with a fluid source. According to the invention, new liquids are supplemented form other loops of a system through suction effects of the vacuum generators, flows passing through the pressure regulation apparatus are increased, the purpose of reducing energy loss of the fluid pressure regulation apparatus is realized, a certain energy-saving effect is generated, and at the same time, the stability of the novel fluid pressure regulation apparatus is better than that of a conventional fluid pressure regulation apparatus.

Description

technical field [0001] The invention belongs to the technical field of fluid transmission, and in particular relates to a novel fluid pressure regulating device and a fluid pressure regulating method thereof. Background technique [0002] In existing hydraulic or pneumatic systems, pressure regulating devices, such as pressure reducing valves, are often used. People often overlook the energy consumption of the pressure regulating device. In fact, the energy consumption of the pressure reducing valve is one of the highest components in the fluid system. Taking the pneumatic system as an example, a typical pneumatic system usually consists of an air compressor 01, an air conditioning unit 02, a piping system 03, a fluid pressure regulating device 04 (such as a pressure reducing valve) and a terminal pneumatic load 05. Such as figure 1 As shown, the air compressor 01 consumes electric energy to generate high-pressure air (pressure reaches 0.7~1.0 MPa); the high-pressure air...

Problems solved by technology

The higher the pressure at the discharge port of the vacuum generator, the weaker the vacuum at the suction port, and the weaker the suction force of the rubber suction cup.
