[0022] Example
[0023] like Figure 1 As shown, the control cabinet for pressurizing low-pressure fluid with high-pressure air in this embodiment includes a cabinet 1, a high-pressure gas cylinder 2, an air pressurization device 3, and an electronic pressure detector 4. The high-pressure gas cylinder 2 and the air pressurization device 3 are respectively installed in the cabinet 1. The gas outlet of the high-pressure gas cylinder 2 is connected to a gas supply line 5. The upstream of the gas supply line 5 is provided with a detection port and connected to the electronic pressure detector 4. The middle section of the gas supply line 5 is provided with a control valve 6. The upstream of the gas supply line 5 is connected to a pressurization branch pipe 7. The air pressurization device 3 is connected to the pressurization branch pipe 7. The pressurization branch pipe 7 is provided with a gas check device. The end of the gas supply line 5 away from the high-pressure gas cylinder 2 is connected to a high-pressure air connector.
[0024] The control cabinet of the embodiment utilizes high-pressure air to pressurize low-pressure fluid, and the main purpose is to output high-pressure air, which is connected to the high-pressure air pressurized low-pressure fluid device at the rear end. During use, the air compression device 3 compresses and stores air in the high-pressure gas cylinder 2. When high-pressure air needs to be output, the control valve 6 is opened, and the high-pressure gas in the high-pressure gas cylinder 2 is output from the pipeline connected to the high-pressure air joint along the gas pipeline 5. During the whole process, the electronic pressure detector 4 detects the gas pressure in the high-pressure gas cylinder 2 in real time. When the gas pressure reaches the set threshold, the air compression device 3 stops running. When the gas pressure is lower than the set threshold, the air compression device 3 starts running, and the control valve 6 is closed synchronously. The compression branch pipe 7 inputs compressed air into the high-pressure gas cylinder 2 until the gas pressure reaches the set threshold, and then stops running. The overall structure is simple and reasonable, and can guarantee stable and reliable high-pressure gas supply.
[0025] In the embodiment, the cabinet body 1 is divided into a lower cavity and an upper cavity by a partition, the high-pressure gas cylinder 2 is installed in the lower cavity, and the air compression device 3 is installed at the upper end of the partition. The internal design of the cabinet body 1 is simple, which is beneficial to the placement of the air compression device 3 and the high-pressure gas cylinder 2. Preferably, a support adapted to the horizontally placed high-pressure gas cylinder 2 is arranged on the inner bottom wall of the cabinet body 1. The upper surface of the support is concavely provided with a receiving groove with a circular arc cross section. The high-pressure gas cylinder 2 is embedded in the receiving groove after being placed horizontally, which is beneficial to the stable placement of the high-pressure gas cylinder 2.
[0026] As a preferred embodiment, the control valve 6 is an electromagnetic valve, and the control valve 6, the air compression device 3, and the electronic pressure detector 4 are respectively connected to the controller 9.
[0027] In the above embodiment, the controller 9 is connected to a power supply to supply power to the control valve 6, the air compression device 3, and the electronic pressure detector 4. The electronic pressure detector 4 monitors the pressure in real time and feeds back to the controller 9. The controller 9 controls the running state of the air compression device 3 and the opening and closing state of the control valve 6 according to the feedback pressure data. Specifically, when the pressure value is lower than the set threshold, the control valve 6 is closed, and the air compression device 3 is opened to inject compressed air into the high-pressure gas cylinder 2 to increase the pressure until the set threshold is reached, and then the air compression device 3 stops running. After that, the control valve 6 can be opened to output high-pressure gas. The whole process can realize automatic pressure increase (pressure compensation).
[0028] In the embodiment, the electronic pressure detector 4 adopts a commercially available electronic pressure gauge of an appropriate model.
[0029] In the embodiment, the air compression device 3 adopts a commercially available air compressor of an appropriate model.
[0030] In the embodiment, the gas check valve is used in the gas check device. The check valve only allows the gas to be pressed into the high-pressure gas cylinder 2 through the air press device 3, and does not allow the gas to flow back, thereby ensuring effective pressurization.
[0031] In the embodiment, the downstream of the gas pipeline 5 is provided with a pressure reducing valve 10. The pressure reducing valve 10 is a commercially available pressure reducing valve 10. Generally, the pressure reducing valve 10 has an output and an input pressure gauge, and the input and output pressure data can be directly observed.
[0032] As a preferred embodiment, the high-pressure gas cylinder 2 is provided with two groups. The gas outlets of the two groups of high-pressure gas cylinders 2 are connected to two interfaces of a first three-way valve 21 through pipelines, and the remaining one interface of the first three-way valve 21 is connected to the gas pipeline 5.
[0033] In the embodiment, the high-pressure gas cylinder 2 is provided with two groups, which can realize “one standby and one use”. Specifically, when one of the high-pressure gas cylinders 2 stops outputting high-pressure gas due to insufficient internal pressure, the air press device 3 can be used to charge and pressurize the high-pressure gas cylinder 2 with insufficient pressure.
[0034] Of course, the two high-pressure gas cylinders 2 can also be connected in parallel, and connected to the gas pipeline 5 through pipelines, respectively. Each pipeline is connected to a group of pressurizing branch pipes 7 and a gas check device.
[0035] In the embodiment, the upstream of the gas pipeline 5 is connected in series with a second three-way valve 51, and the remaining one interface of the second three-way valve 51 constitutes the detection port.
