Description
Technical field
The invention belongs to high-pressure pneumatic system technical field, relate to a kind of high-voltage electrical apparatus ratio pressure regulating system, object is that the accurate pressure that solves high-pressure system regulates problem.
Background technique
At present, the comparative maturity of design of low-pressure pneumatic element (working pressure is lower than 1.0MPa), also fewer for research and the application of high-pressure pneumatic element.Along with industry-by-industry particularly national defense industry the requirement of system high-speed degree, high pressure is constantly increased, simultaneously also because high-pressure pneumatics can effectively be improved pneumatic system dynamic performance and rigidity, there is ouput force system weight than little, can realize speed up and miniaturization of components, thereby save the advantages such as installing space, high-pressure pneumatics more and more comes into one's own.
In air motor suction pressure control gear, in order to ensure the output torque of motor and the requirement of speed, pressure and the flow that must export gas to gas cylinder are controlled in real time, require control unit to have short, the feature such as dynamic performance is good of response time.Because the application of high-pressure pneumatics is at present mainly reflected in national defense industry field, over nearly 10 years, the external rare report of research in high-pressure pneumatics field.Domestic the research work of high-pressure pneumatic element is mainly concentrated on to Reduction of High Pressure Pneumatic valve aspect at present, have no report for the research of high-pressure pneumatic electric Proportion valve.
For this situation, the present invention proposes a kind of high-voltage electrical apparatus ratio regulating system.
Summary of the invention
Object of the present invention: proposed a kind of high-voltage electrical apparatus ratio pressure regulating system, so that the delivery pressure of accuracy-control system.
Technological scheme of the present invention:
Described system comprises: pressure regulator valve (1), low-voltage electrical Proportional valve (2), Air pressure control release valve (3) and connection three's gas piping.Air pressure control release valve (3) Access Control branch road and work branch, wherein the series connection of pressure regulator valve (1) and low-voltage electrical Proportional valve (2) is as controlling branch road, and the gas piping that directly flows to Air pressure control release valve is work branch.In control branch road, pressurized gas lead to pressure regulator valve (1) by gas piping, gas pressure drops to the range of working pressure of low-voltage electrical Proportional valve (2) subsequently for its work, low-voltage electrical Proportional valve (2) regulates its output gas pressure according to received electrical signal and input pressure signal, then this output gas is inputted as a road, supplies with Air pressure control release valve (3) carry out work by gas piping; In work branch, the pressurized gas of air machinery output directly connect Air pressure control release valve (3) by gas piping, the gas pressure signal that Air pressure control release valve (3) receives according to control loop, spool is moved down accordingly and then obtain corresponding aperture, and then the delivery pressure of regulating system.
Advantage of the present invention:
The present invention can utilize the accurate advantage control of current low-voltage electrical proportional valve control high-voltage electrical apparatus Proportional valve, reliable in work, realizes easily.
Brief description of the drawings:
Fig. 1 is systematic schematic diagram of the present invention.
1. pressure regulator valve, 2. low-voltage electrical Proportional valve, 3. Air pressure control release valve
Embodiment
The electric ratio gas handling system of air motor as shown in Figure 1, after the pressurized gas of air machinery storage discharge, enters high-voltage electrical apparatus ratio pressure regulating system by gas piping.Pressurized gas are divided into two-way after entering high-voltage electrical apparatus ratio pressure regulating system, flow through pressure regulator valve (1) and low-voltage electrical Proportional valve (2) Yi road of pressurized gas is called control branch road, and pressurized gas directly flow to Air pressure control release valve (3) Yi road by gas piping and are called work branch.In control branch road, pressurized gas lead to pressure regulator valve (1) by gas piping, gas pressure drops to the range of working pressure of low-voltage electrical Proportional valve (2) subsequently for its work, low-voltage electrical Proportional valve (2) regulates its output gas pressure according to received electrical signal and input pressure signal, then this output gas is inputted as a road, supplies with Air pressure control release valve (3) carry out work by gas piping; In work branch, the pressurized gas of air machinery output directly connect Air pressure control release valve (3) by gas piping, the gas pressure signal that Air pressure control release valve (3) receives according to control loop, spool is moved down accordingly and then obtain corresponding aperture, and then the delivery pressure of regulating system.
