Abstract

The invention discloses an air-pressure type constant-pressure liquid supply device. A liquid-storage container is a closed container; an exhaust valve is arranged at the top of the liquid-storage container; and an air bag is arranged in the liquid-storage container. A high-pressure air bottle is connected with an air bottle valve through a high-pressure air pipe; the air bottle valve is connected with a tee joint through another high-pressure air pipe; a left connector of the tee joint is connected with an air bottle barometer, a press-reducing valve, a barometer and a pressure release valvein sequence through another high-pressure air pipes; the pressure release valve is connected with the air bag through a seventh compressed air pipe; and a right connector of the tee joint is connected with an air supply valve, a safety valve and an air pressure source in sequence through another high-pressure air pipes. A liquid supply pipe is arranged at the bottom of the right side wall of the liquid-storage container; a right connector of the liquid supply pipe is connected with a precision digital hydraulic pressure gauge which is connected with a liquid supply valve through the liquid supply pipe; a liquid inlet pipe is arranged at the bottom of the left side wall of the liquid-storage container; and a left connector of the liquid inlet pipe is connected with the liquid inlet valve. The invention has simple structure and convenient operation, can realize constant-pressure liquid supply and can be used for soil seepage tests and earth pillar leaching tests.

Description

technical field [0001] The invention relates to the technical field of experimental measuring instruments, in particular to a pneumatic constant pressure liquid supply device, which provides a constant pressure supply device with stable pressure and long-term operation without power supply for scientific experiments such as soil seepage test and soil column leaching test. liquid device. Background technique [0002] Hydraulic experiment is a kind of basic physical mechanics experiment, and it is one of the main research methods of hydraulics and seepage mechanics research, and a complete set of constant pressure liquid supply device is the necessary equipment for hydraulic experiments. [0003] At present, the commonly used liquid supply devices are generally float type and self-overflow liquid supply devices, which are relatively popular liquid supply devices, and their functions are relatively single, which cannot meet the test accuracy requirements in the fields of scient...
