Embodiment 1

[0068] combine Figure 1 to Figure 4 As shown, the present embodiment provides a pressure regulating device, which includes a gas storage chamber 1, a drive unit 4 and a first valve 5; the gas storage chamber 1 is provided with a push plate 2, and the side wall of the push plate 2 Sliding and sealing cooperation with the inner wall of the air storage chamber 1 to separate the air storage chamber 1 into a fluid chamber 1-1 and an adjustment chamber 1-2, the fluid chamber 1-1 is used to store fluid medium; the drive unit 4 communicates with the The push plate 2 is connected to drive the push plate 2 to move along the length direction of the air storage chamber 1; the first end of the first valve 5 communicates with the fluid chamber 1-1 through the fluid pipeline 7, and the second end is used to communicate with the to-be-regulated The external pressure chamber 6 communicates. Wherein, the fluid medium is gas or liquid.

[0069] Such as Figure 5 As shown, when the external p...

Embodiment 2

[0095] This embodiment provides a method for using a pressure regulating device, the method comprising the following steps:

[0096] Such as Figure 8 As shown, when inflated:

[0097] S1.0', device initialization, and jump to step S1.0;

[0098] S1.0. Set the preset inflation pressure on the controller 9, and skip to step S1.1;

[0099] S1.1, open the first valve 5, close the second valve 8, and skip to step S1.2;

[0100] S1.2. Obtain the fluid pressure of the external pressure chamber 6 through the first pressure sensor 10, and skip to step S1.3;

[0101] S1.3. Determine whether the fluid pressure of the external pressure chamber 6 is lower than the preset inflation pressure, if so, skip to step S1.4, otherwise skip to step S1.5;

[0102] S1.4. Start the drive unit 4 to drive the push plate 2 to move towards the first end 1-3 of the air storage chamber, and skip to step S1.2; wherein, the first end 1-3 of the air storage chamber is One end of the gas storage chamber 1 ...

Embodiment 3

[0128] Such as Figure 11 As shown, the present embodiment provides a pressure regulating system, which includes a general controller 13 and a plurality of above-mentioned pressure regulating devices, and all controllers 9 are electrically connected to the general controller 13 . Wherein the general controller 13 may be but not limited to a computer, and the controller 9 may be but not limited to a PLC controller. The pressure regulating system can be applied to fields such as flexible robots, industrial production lines, and medical auxiliary breathing devices, and all pressure regulating devices can be coordinated and controlled by the general control.

[0129] For example, when the pressure regulating system is installed on the pneumatic manipulator, a pressure regulating device can be connected on each pneumatic finger of the pneumatic manipulator, and the master controller 13 can charge / Deflate for independent movement.

Abstract

The invention relates to the field of pressure regulating equipment, and provides a pressure regulating device, a use method of the pressure regulating device and a pressure regulating system. The pressure regulating device comprises an air storage chamber, a driving unit and a first valve, wherein a push plate is arranged in the air storage chamber; the side wall of the push plate is in sliding sealing fit with the inner wall of the air storage chamber to divide the air storage chamber into a fluid chamber and an adjusting chamber; the fluid chamber is used for storing a fluid medium; the driving unit is connected with the push plate through a push rod and is used for driving the push plate to move along the length direction of the air storage chamber; a first end of the first valve communicates with the fluid chamber through a fluid pipeline; and a second end of the first valve communicates with an external pressure chamber to be regulated. The pressure regulating system comprises amain controller and a plurality of the pressure regulating devices. By means of the use method of the pressure regulating device, not only can positive pressure be provided for the external pressure chamber, but also negative pressure can be provided for the external pressure chamber, so that multiple purposes integrated into one device is achieved, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of pressure regulating equipment, in particular to a pressure regulating device, a method for using the same, and a pressure regulating system. Background technique [0002] At present, the pressure adjustment range of the existing pressure regulating equipment is relatively small, and can only provide positive pressure or negative pressure to the external pressure chamber to be adjusted. Take the most widely used compressor and vacuum pump in the market as an example. Since the compressor can only provide positive pressure and the vacuum pump can only provide negative pressure, it is necessary to equip both compressor and vacuum pump for occasions that sometimes require positive pressure and sometimes require negative pressure. , and this will inevitably increase the complexity of the system structure and increase the cost. Contents of the invention [0003] What the present invention aims to solve is that the pre...
