Description

Technical Field

[0001] The utility model mainly relates to the technical field of special gas distribution terminals, and particularly relates to a special gas distribution terminal with automatic pressure regulation. Background Technique

[0002] Special gases usually refer to gases produced to meet specific uses, including single gases or mixed gases. These gases are widely used in fields such as electronics, electric power, petrochemical industry, mining, steel, non-ferrous metal smelting, thermal engineering, biochemistry, environmental monitoring, medical research and diagnosis, food preservation, etc. There are many categories of special gases, such as electronic gases, standard gases, environmental protection gases, medical gases, welding gases, sterilization gases, etc. When supplying gases to gas-using instruments such as experimental instruments and analytical instruments, the pressure is set to a constant pressure according to the demand for constant-pressure gas supply. The special gas supply system needs to operate at a constant pressure mainly to ensure the stability and safety of the system. In the application of special gases, different gases have different physical and chemical properties, such as flammable, explosive, toxic, etc. If the system pressure fluctuates, it may lead to serious consequences such as gas leakage, explosion, or poisoning. Therefore, operating at a constant pressure can ensure that the system can provide a stable and safe gas supply under various working conditions.

[0003] In the prior art, a pneumatic control valve is used to adjust the gas supply pressure, such as the AR2000 pressure regulator. When the above pressure regulator is in use, the adjustment knob needs to be lifted upwards first, and then the knob is rotated to adjust the pressure. After the adjustment is completed, the adjustment knob is pressed and locked. However, the adjustment accuracy of the manual pressure regulator is relatively low, and it is difficult to meet the requirements of the special gas supply for pressure stability. The operation of the manual pressure regulator is not convenient and requires manual adjustment, making it difficult to achieve automatic control. Content of the Utility Model

Embodiment

[0028] Referring to the attached Figures 1 to 5 , an automatic pressure-regulating special gas distribution terminal includes a special gas storage chamber. A special gas cylinder is placed in the special gas storage chamber. The output end of the special gas cylinder is connected to the gas pipe 6 of the gas-using instrument through a solenoid valve 3, a pressure regulator 2, and a docking device 5. The pressure regulator 2 is a pressure regulating valve in the prior art, such as the AR2000 pressure regulator of a certain model. The solenoid valve 3 and the pressure regulator 2 are arranged on the wall panel 1 of the special gas storage chamber. The control knob 21 of the pressure regulator 2 is connected to an automatic regulator 4, and the automatic regulator 4 pushes and pulls the control knob 21 and drives the control knob 21 to rotate.

[0029] The automatic regulator 4 includes a mounting plate 401. The mounting plate 401 is fixed to the wall panel 1 through support columns 402. A first cylinder 403 is fixedly mounted on the mounting plate 401. A connecting plate 404 is fixedly mounted on the output end of the first cylinder 403. A spline shaft 405 is rotatably mounted on the connecting plate 404. A support seat 410 is also mounted on the mounting plate 401. A first synchronous pulley 406 is rotatably mounted on the support seat 410. The spline shaft 405 is slidably mounted vertically at the center of the first synchronous pulley 406. The lower end of the spline shaft 405 is connected to the control knob 21. The first synchronous pulley 406 is connected to the driving mechanism.

[0030] The driving mechanism includes a motor 409 fixed on the mounting plate 401. A second synchronous pulley 408 is fixedly mounted on the motor shaft of the motor 409. The second synchronous pulley 408 is connected to the first synchronous pulley 406 through a synchronous belt 407.

[0031] A positioning ring 411 is also provided on the mounting plate 401. The positioning ring 411 is concentric with the spline shaft 405. The control knob 21 is arranged inside the positioning ring 411.

[0032] The docking device 5 includes a connecting block 51 fixed to the wall panel 1. A second cylinder 52 and a third cylinder 53 are symmetrically mounted on the connecting block 51. A first slider 54 is fixedly mounted on the piston rod of the second cylinder 52. A second slider 55 is fixedly mounted on the third cylinder 53. A first docking cylinder 56 is fixedly mounted on the first slider 54. A second docking cylinder 57 is fixedly mounted on the second slider 55. Both the first docking cylinder 56 and the second docking cylinder 57 are slidably mounted on a connecting cylinder 58. The first docking cylinder 56 is sleeved on the air outlet pipe 22 of the air pressure regulator 2. The second docking cylinder 57 is connected to the gas pipe 6.

[0033] Working principle:

[0034] Pressure sensors are installed on both the air pressure regulator 2 and the gas supply pipeline for real-time monitoring of the gas supply pressure. The pressure sensors are connected to the controller to transmit the pressure signals to the controller.

[0035] Then it is necessary to set the target pressure, that is, the constant pressure value required for the supply of special gases. The controller opens and adjusts the supply pressure of the pneumatic pressure regulator 2 through the automatic regulator 4, starts the first cylinder 403, the piston rod of the first cylinder 403 extends, drives the spline shaft 405 to move outwards through the connecting plate 404, that is, unlocks the safety of the control knob 21, and then starts the motor 409. When the motor shaft rotates, the second synchronous pulley 408 also rotates accordingly. Through the synchronous belt 407, this rotational movement is transmitted to the first synchronous pulley 406. The first synchronous pulley 406 drives the spline shaft 405 to rotate, thereby driving the control knob 21 to rotate to set the supply pressure. After the setting is completed, the motor 409 stops rotating, and the first cylinder 403 drives the control knob 21 to reset and lock.

[0036] The automatic regulator 4 adjusts the supply gas flow by controlling the opening of the solenoid valve 3 according to the signal fed back by the pressure sensor, thereby realizing the adjustment of the supply pressure. The controller system will monitor the supply pressure in real time and automatically adjust the opening of the solenoid valve 3 and the settings of the pneumatic pressure regulator 2 according to the actual situation to maintain the constancy of the supply pressure.

[0037] Through the above steps, it is possible to realize the automatic adjustment of the supply pressure through the solenoid valve 3, the pneumatic pressure regulator 2 and the automatic regulator 4, so that the supply of special gases maintains a constant pressure. This automatic adjustment system can improve the stability and reliability of the gas supply, ensuring the normal use of special gases. At the same time, it can also reduce manual intervention and improve work efficiency.

[0038] Automatically adjust the pressure and supply a constant pressure of gas through the solenoid valve 3, the pneumatic pressure regulator 2 and the automatic regulator 4. By automatically adjusting the pressure, it can ensure that the supply pressure always remains within the set value range, avoiding problems such as unstable and unreliable gas supply caused by pressure fluctuations. The automatic regulator 4 can accurately adjust the supply pressure according to the needs of the gas-using instrument, thereby improving the accuracy and precision of the gas supply. By automatically adjusting the pressure, it can avoid gas waste and energy consumption caused by too high pressure, thereby improving the efficiency and energy-saving performance of the gas supply. The automatic regulator 4 reduces the costs of manual intervention and maintenance, and improves the automation level and intelligent level of the gas supply system.

[0039] The second cylinder 52 and the third cylinder 53 respectively push the first slider 54 and the second slider 55, so that the first docking cylinder 56 and the second docking cylinder 57 slide on the connecting cylinder 58. The first docking cylinder 56 is sleeved on the air outlet pipe 22 of the air pressure regulator 2, and the second docking cylinder 57 is connected to the gas pipe 6 to realize the transportation of special gas. When it is necessary to disconnect the connection, the second cylinder 52 and the third cylinder 53 respectively pull the first slider 54 and the second slider 55, so that the first docking cylinder 56 and the second docking cylinder 57 slide reversely on the connecting cylinder 58, thereby disconnecting the connection with the air outlet pipe 22 of the air pressure regulator 2 and the gas pipe 6. In this way, the docking device 5 can automatically connect or disconnect the gas pipe 6 of the gas-using instrument, improving the convenience and efficiency of operation. The docking device 5 can automatically connect or disconnect the gas pipe 6 of the gas-using instrument, avoiding the problems of low connection efficiency and inaccurate connection caused by manual operation. At the same time, it reduces the connection safety hazards and unreliable connection problems caused by manual operation, improving the automation degree and intelligent level of the gas supply system.
