[0020] In this invention, specifically, the signal input terminals of the programmable logic controller (PLC) 13 are connected to the pressure input terminal 11 and the flow input terminal 12, respectively.

[0021] In this invention, specifically, the second control signal output terminal of the programmable logic controller (PLC) 13 is connected to the input terminal of the automatic and manual switching switch 14; The output of the automatic / manual switching switch 14 is connected to the wiring input of the terminal block 15.

[0022] It should be noted that the pressure input terminal 11 and flow input terminal 12 of the central control panel 1 are connected to the programmable logic controller (PLC) 13 by the first line 61 (which is a communication cable) and the second line 62, respectively. The programmable logic controller (PLC) 13 is electrically connected to the electrical components in the control panel 2, pump source 3, and main cabinet 4 through the wiring terminals. The three-way switch 16 is used to control the on / off switching of the positive pressure pump source 32 and the negative pressure pump source 31.

[0023] In this invention, the output end of the first pressure regulating valve 33 and the output end of the second pressure regulating valve 34 are respectively connected to the first interface and the second interface of the first three-way valve 71. The third interface of the first three-way valve 71 is connected to the inlet end of the energy storage tank 41 in the main cabinet 4 through the third pressure regulating valve 21.

[0024] In specific implementation, the input end of the third pressure regulating valve 21 is connected to the third interface of the first three-way valve 71; The output end of the third pressure regulating valve 21 is connected to the first interface of the first four-way valve 81; The second interface of the first four-way connector 81 is connected to the detection end of the pressure gauge 22; The third interface of the first four-way connector 81 is connected to the inlet end of the energy storage tank 41; The fourth port of the first four-way valve 81 is connected to the input terminal of the first shut-off valve 23; The output end of the first shut-off valve 23 is connected to the input end of the first pressure relief valve 25 through the second four-way valve 82; The output end of the first pressure relief valve 25 serves as the pressure relief port 43 of the manual-automatic integrated pressure environment regulation system.

[0025] The first shut-off valve 23 of the control panel 2 is located on the pipeline between the first pressure relief valve 25 and the third pressure regulating valve 21. After opening the first shut-off valve 23, the pressure can be finely adjusted in manual mode by rotating the adjustment knob of the third pressure regulating valve 21.

It should be noted that one end of the first pressure relief valve 25 is connected to the energy storage tank 41 through a pipeline, and the other end is connected to the pressure relief port 43 of the main cabinet 4. When the pressure in the energy storage tank 41 exceeds the set threshold, the first pressure relief valve 25 automatically opens to discharge the excess pressure through the pressure relief port 43, thereby achieving overpressure protection.

[0026] It should be noted that the energy storage tank 41 of the main cabinet 4 adopts a high-pressure resistant sealing structure, which can be adapted to the storage and buffering of different media such as air pressure, water pressure, and oil pressure, effectively mitigating the pressure fluctuations caused by the start and stop of the pump source, and ensuring the stability of the pressure and flow of the total output port 44.

[0027] It should be noted that the pressure gauge 22 on the control panel is connected to the output pipeline of the main cabinet 4 for real-time monitoring of the output pressure value; the flow meter 24 is electrically connected to the flow meter 42 for real-time display of the medium flow rate; the third pressure regulating valve is connected to the first tee 71 through a pipeline to achieve fine pressure adjustment in manual mode; the first shut-off valve 23 is installed in the main pipeline of the control panel for controlling the pipeline opening and closing; and the first pressure relief valve 25 is connected to the pipeline of the energy storage tank 41 of the main cabinet for pressure relief protection in case of overpressure.

[0029] In this invention, specifically, the pressure input terminal 11 and the flow input terminal 12 can be existing mature input devices with data and signal input functions, such as touch screen computers.

[0030] In this invention, specifically, the automatic and manual switching switch 14 is a conventional and widely used switch component, which will not be described in detail here.

[0031] In this invention, specifically, the positive pressure pump source 32 can be a conventional, widely used positive pressure pump, and the negative pressure pump source 31 can be a conventional, widely used negative pressure pump; further details will not be provided here. All components used in the system of this invention are conventional industry technologies and will not be described in detail here.

[0032] To better understand the technical solution of the present invention, the working mode of the present invention is described below.

[0033] The manual / automatic integrated pressure environment regulation system provided by this invention includes the following two working modes: 1. Automatic mode; The automatic mode is as follows: the automatic and manual switch 14 of the central control panel 1 is switched to the automatic position, and the preset pressure value and flow value are input to the programmable logic controller 13 through the pressure input terminal 11 and the flow input terminal 12. The programmable logic controller 13 automatically controls the positive pressure pump source 32 or the negative pressure pump source 31 of the pump source 3 to start according to the set value, and adjusts the opening of the first pressure regulating valve 33 or the second pressure regulating valve 34. After the pressure medium is buffered by the energy storage tank 41, the flow rate is monitored by the flow meter 42, and finally it is stably output from the main output port 44. In automatic mode, when the pressure of the total output port 44 collected by the pressure gauge 22 or the flow rate of the total output port 44 collected by the flow meter 24 deviates from the set value, the programmable logic controller 13, which is connected to the pressure gauge and the flow meter 24, can adjust the parameters of the pump source and the pressure regulating valve in real time to achieve automatic and precise adjustment.

[0034] II. Manual Mode; The manual mode is as follows: switch the automatic and manual switch 14 on the central control panel 1 to the manual position, turn off the automatic control function of the pump source 3, open the first shut-off valve 23 on the control panel 2, adjust the pipeline pressure by rotating the adjustment knob of the third pressure regulating valve 21, and combine the real-time display data of the pressure gauge 22 and the flow meter 24 to achieve manual fine adjustment of pressure and flow. During manual operation, if the pressure inside the energy storage tank 41 exceeds the limit, the first pressure relief valve 25 will automatically open to release pressure and ensure equipment safety.

[0035] Therefore, the present invention can replace the pressure medium according to actual needs. When replacing, it is only necessary to drain the original medium in the pipeline and the storage tank 41, clean the pipeline, and then connect the new medium. The operation is simple. At the same time, by replacing the pressure regulating valve and flow meter of different specifications, the adjustment range of pressure and flow can be expanded, and the adaptability of the equipment can be further improved.

[0036] Compared with the prior art, the manual / automatic integrated pressure environment regulation system provided by the present invention has the following beneficial effects: 1. This invention has both positive and negative pressure regulation functions, and is equipped with independent positive and negative pressure pump sources. It can be flexibly switched through a three-way switch as needed. At the same time, the pressure medium can be freely changed to air pressure, water pressure, or oil pressure, which can meet the pressure environment regulation needs of different industries and has a wide range of applications.

[0037] 2. This invention is equipped with an automatic and manual switching switch. In automatic mode, the PLC precisely controls the pump source and pressure regulating valve according to the set values ​​of the pressure input terminal and the flow input terminal to achieve automatic adjustment of pressure and flow. In manual mode, fine adjustment can be made through the third pressure regulating valve, the first shut-off valve and the first pressure relief valve on the control panel. The two modes can be switched seamlessly, taking into account both control accuracy and operational flexibility.

[0038] Third, the control pressure range and flow rate of this invention are adjustable. Through the cooperation of the first pressure regulating valve and the second pressure regulating valve of the pump source and the third pressure regulating valve of the control panel, the pressure can be adjusted in multiple levels. The flow meter and flow meter work together to monitor and adjust the flow rate in real time. At the same time, an energy storage tank is provided to ensure stable pressure and flow output. The first pressure relief valve and the pressure relief port form a double overpressure protection, which ensures high safety in use.

[0039] Fourth, this invention integrates four major modules: central control console, control panel, pump source, and main cabinet. It has a compact structure, neat pipeline and circuit layout, and intuitive operation interface, which facilitates on-site operation and remote control. At the same time, each module is designed independently, which facilitates maintenance and parts replacement, and reduces the cost of equipment use and maintenance.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
