A novel gas-liquid mixed power ejection device comprises a hydraulic cylinder, an accumulator and a main valve, wherein the lower chamber of the hydraulic cylinder is communicated with the gas part of the accumulator; the gas part of the accumulator is provided with a pressure sensor; the liquid part of the accumulator is connected with the oil outlet of a first 2D digital valve and the oil inletof the main valve; the oil outlet of the main valve is communicated with the oil port of the upper chamber of the hydraulic cylinder; the oil inlet of the first 2D digital valve is connected with a hydraulic power supply; the oil outlet of the first 2D digital valve is communicated with the oil inlet of a second 2D digital valve and the oil inlet of a third 2D digital valve; the oil outlet of thesecond 2D digital valve is communicated with the control oil port of the main valve; the oil outlet of the third 2D digital valve is communicated with the oil port of the upper chamber of the hydraulic cylinder; and the pressure sensor, the first 2D digital valve, the second 2D digital valve and the third 2D digital valve are all connected with a digital valve controller which is used to control the on / off of each 2D digital valve. The novel gas-liquid mixed power ejection device has many functions, high efficiency and good safety.
Description
technical field [0001] The invention relates to the field of ejection devices, in particular to a gas-liquid hybrid ejection device. Background technique [0002] In terms of ejection energy, ejection devices are divided into cannon type, hydraulic type, compressed air type, hydraulic-pneumatic type, gas type, gas-steam type and electromagnetic type. The application occasions of the ejection mechanism are special, and there are strict requirements on the weight and dynamic response performance of the system. The ejection device with superior performance has been actively developed at home and abroad. The traditional ejection device has single function and low efficiency. Contents of the invention [0003] In order to overcome the disadvantages of existing ejection devices such as single function, low efficiency and poor safety, the present invention provides a gas-liquid hybrid ejection device with rich functions, high efficiency and excellent safety. [0004] The techni...
