Description

Technical Field

[0001] This utility model relates to the field of boosting, and in particular to a multi-intake gas boosting system. Background Technology

[0002] A booster pump is a type of pump that converts a low-pressure input into a high-pressure output using the principle of piston area difference. During operation, it can automatically start and stop according to pressure changes, maintaining a constant pressure. When gas needs to be pressurized, the gas to be pressurized is input into the booster pump, and then output after pressurization.

[0003] The existing booster pump has only one input air path. When it is necessary to boost different types of gas, it is necessary to disconnect and reconnect different gas sources from the input air path. Since the connecting parts of the air path need to be welded to the gas source pipes, disassembly is inconvenient. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a multi-intake gas booster system that can be used with different types of gas sources.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] A multi-intake gas booster system includes a hydraulic station and a booster pump. The booster pump has a drive chamber, a first compression chamber, and a second compression chamber. The drive chamber is located between the first compression chamber and the second compression chamber. The multi-intake gas booster system also includes an intake structure, which includes an intake pipe, a converter assembly, a connecting assembly, and multiple intake components. Each intake component includes a connector, a solenoid valve, and a first check valve connected in sequence. The connectors of the multiple intake components are fixed and connected to connecting pipes of different gas sources. The solenoid valve controls the on / off state of the intake components. The connecting assembly is connected to the multiple intake components. The converter assembly is connected to the connecting assembly and is connected to the second compression chamber, allowing the gas to be compressed entering the multiple intake components to enter the second compression chamber. One end of the intake pipe is connected to the converter assembly, and the other end of the intake pipe is connected to the first compression chamber. The intake pipe inputs the gas to be compressed entering the multiple intake components into the first compression chamber.

[0007] Furthermore, the connecting component includes an extension tube and a third connector installed on the extension tube. The third connector is a two-way connector or a three-way connector. There are multiple third connectors, and each third connector is connected to one of the air intake components.

[0008] Furthermore, the adapter assembly includes an adapter block, a fourth connector, and a fifth connector. The fourth connector and the fifth connector are fixed to both sides of the adapter block. The fourth connector is connected to the third connector, the fifth connector is connected to the air intake pipe, and the middle part of the adapter block is connected to the second compression chamber.

[0009] Furthermore, the adapter assembly also includes a second one-way valve, which is installed between the adapter block and the second compression chamber.

[0010] Furthermore, the second one-way valve includes a valve seat, an elastic element, and a top ball. The elastic element and the top ball are mounted on the valve seat. One end of the elastic element abuts against the valve seat, and the other end abuts against the top ball. The elastic force of the elastic element abuts against the top ball, causing the top ball to block the air hole of the adapter block.

[0011] Furthermore, the valve seat is a hollow cylinder, and the side wall of the valve seat has an opening. When at least one of the air intake components is inlet, the top ball is pressed by the gas and moves along the valve seat, so that the adapter block communicates with the second compression chamber through the opening.

[0012] Furthermore, the booster pump includes a first end plate and a second end plate. The first end plate is located at the end of the first compression chamber and forms the side wall of the first compression chamber. The second end plate is located at the end of the second compression chamber and forms the side wall of the second compression chamber. Both the first end plate and the second end plate are provided with air passages. The adapter block communicates with the second compression chamber through the air passage of the second end plate. The air intake pipe communicates with the first compression chamber through the air passage of the first end plate.

[0013] Furthermore, the intake pipe is fitted between the first end plate and the second end plate.

[0014] Furthermore, the multi-intake gas booster system also includes an exhaust pipe, which is fitted between the first end plate and the second end plate. The exhaust pipe is connected to the second compression chamber through the air passage of the second end plate, and the exhaust pipe is connected to the first compression chamber through the air passage of the first end plate.

[0015] Furthermore, the booster pump also includes a piston assembly, which includes a fixed shaft, a drive piston, a first compression piston, and a second compression piston. The drive piston, the first compression piston, and the second compression piston are fixed to the fixed shaft. The drive piston is located in the drive chamber, the first compression piston is located in the first compression chamber, and the second compression piston is located in the second compression chamber.

[0016] Compared to existing technologies, the booster pump of this multi-intake gas booster system has a drive chamber, a first compression chamber, and a second compression chamber. The drive chamber is located between the first and second compression chambers. The multi-intake gas booster system also includes an intake structure, which includes an intake pipe, a connecting assembly, a connecting assembly, and multiple intake components. Each intake component includes a connector, a solenoid valve, and a first check valve connected in sequence. The connectors of the multiple intake components are fixed and connected to connecting pipes of different gas sources. The solenoid valve controls the on / off state of the intake components. The connecting assembly is connected to the multiple intake components. The connector and the connecting assembly are connected to the connecting assembly. The connecting component and the adapter assembly are connected to the second compression chamber, allowing the gas to be compressed from multiple air intake components to enter the second compression chamber. One end of the air intake pipe is connected to the adapter assembly, and the other end of the air intake pipe is connected to the first compression chamber. The air intake pipe inputs the gas to be compressed from multiple air intake components into the first compression chamber. Through the above design, the connecting components of multiple air intake components are fixed and connected to the connecting pipes of different air sources. When it is necessary to compress different types of air sources, it is only necessary to control the on / off state of different air intake components through the solenoid valve to achieve the switching of different air sources. There is no need to disassemble and assemble different types of air sources with the same air intake component, which is convenient to use. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figures 1 to 8 The multi-intake gas booster system of this utility model includes a hydraulic station 10, a reversing valve 20, a pipe body 30, a booster pump 40, an intake structure 50, and an outlet pipe 60.

[0030] The hydraulic station 10 is used to output hydraulic oil, which is used to drive the booster pump 40.

[0031] The directional valve 20 is installed in the hydraulic station 10 and is used to control the direction of hydraulic oil output in the hydraulic station 10. The directional valve 20 can control which of the two pipes 30 the hydraulic oil is output through.

[0032] The pipe body 30 is used to connect the hydraulic station 10 and the drive chamber 41 of the booster pump 40. There are two pipe bodies 30. The two pipe bodies 30 are respectively connected to the drive chambers 41 on both sides of the drive piston 441. One pipe body 30 is used to input hydraulic oil into the drive chamber 41, and the other pipe body 30 is used to return oil from the drive chamber 41 to the hydraulic station 10.

[0033] The booster pump 40 has a drive chamber 41, a first compression chamber 42, and a second compression chamber 43, with the first compression chamber 42 and the second compression chamber 43 located on opposite sides of the drive chamber 41. The first compression chamber 42, drive chamber 41, and second compression chamber 43 are aligned on the same straight line. The piston assembly 44 includes a fixed shaft 440, a drive piston 441, a first compression piston 442, and a second compression piston 443, all fixed to the fixed shaft 440. The drive piston 441 is located between the first compression piston 442 and the second compression piston 443. The drive piston 441 is located in the drive chamber 41, the first compression piston 442 is located in the first compression chamber 42, and the second compression piston 443 is located in the second compression chamber 43. A first end plate 45 and a second end plate 46 are located at opposite ends of the booster pump 40, with the first end plate 45 forming the first compression chamber 42 and the second end plate 46 forming the second compression chamber 43. The first end plate 45 and the second end plate 46 are respectively provided with air passages for the input of the gas to be compressed and the output of the compressed gas. The air passage of the first end plate 45 is connected to the first compression chamber 42; the air passage of the second end plate 46 is connected to the second compression chamber 43.

[0034] The intake structure 50 includes multiple intake components 51, a connecting component 52, an adapter component 53, and an intake pipe 54. The multiple intake components 51 are used to connect to different types of gas sources. Specifically, the different types of gas sources include oxygen, nitrogen, carbon dioxide, etc. The multiple intake components 51 are parallel to each other. Each intake component 51 includes a connector 510, a first connector 511, a solenoid valve 512, a second connector 513, a first check valve 514, a second connector 515, and a connecting pipe 516.

[0035] The connector 510 is welded and fixed to the connecting pipe of the air source. The first connector 511 connects the connector 510 and the solenoid valve 512, which controls the on / off state of the air intake assembly 51. The second connector 513 connects the solenoid valve 512 and the first check valve 514, which controls the airflow direction, allowing incoming gas to flow while preventing reverse flow. The second connector 515 connects the first check valve 514 and the connecting pipe 516.

[0036] The connecting assembly 52 includes an extension pipe 520 and a third connector 521. The extension pipe 520 is connected to multiple intake assemblies 51 via the third connector 521. The third connector 521 is a two-way connector or a three-way connector.

[0037] The adapter assembly 53 includes an adapter block 530, a fourth connector 531, a fifth connector 532, and a second one-way valve 533. The adapter block 530 is connected to the communication assembly 52 via the fourth connector 531, and to the intake pipe 54 via the fifth connector 532. The middle portion of the adapter block 530 is connected to the air passage of the second end plate 46, allowing the adapter block 530 to communicate with the second compression chamber 43 through the air passage of the second end plate 46. The second one-way valve 533 is installed between the adapter block 530 and the second end plate 46, allowing input gas to pass through while preventing compressed air from flowing out through this air passage. Specifically, the second one-way valve 533 includes a valve seat 5330, an elastic element 5331, and a top ball 5332, with the elastic element 5331 and the top ball 5332 installed within the valve seat 5330. The elastic element 5331 is a spring. One end of the elastic element 5331 abuts against the valve seat 5330, and the other end abuts against the top ball 5332. The elastic force of the elastic element 5331 drives the top ball 5332 to press against the air hole of the adapter block 530. When there is compressed gas to be input, the compressed gas pushes the top ball 5332, causing the top ball 5332 to separate from the air hole of the adapter block 530, and the air passage is opened.

[0038] The intake pipe 54 is snapped at both ends to the first end plate 45 and the second end plate 46. One end of the intake pipe 54 is connected to the adapter assembly 53, and the other end is connected to the first end plate 45. The intake pipe 54 delivers the input gas to the first compression chamber 42.

[0039] The two ends of the exhaust pipe 60 are snapped into the first end plate 45 and the second end plate 46. The exhaust pipe 60 is parallel to the intake pipe 54. One end of the exhaust pipe 60 is connected to the air passage of the first end plate 45, and the other end is connected to the air passage of the second end plate 46.

[0040] When the multi-intake gas booster system is in use, the hydraulic oil from the hydraulic station 10 is input into the drive chamber 41 of the booster pump 40 through the pipe 30, pushing the drive piston 441 to move, thereby driving the first compression piston 442 and the second compression piston 443 to move and compress the gas. Depending on the type of gas to be compressed, the solenoid valve 512 of the corresponding connected intake assembly 51 is controlled to allow the corresponding gas to enter the intake assembly 51. The gas then enters the first compression chamber 42 and the second compression chamber 43 respectively through the connecting assembly 52, the adapter assembly 53, and the intake pipe 54. The compressed gas is then combined and output through the outlet pipe 60. In this application, the connectors 510 of the multiple intake assemblies 51 are fixed and connected to the connecting pipes of different gas sources. When different types of gas sources need to be compressed, the switching between different gas sources can be achieved simply by controlling the on / off state of the different intake assemblies through the solenoid valve 512. There is no need to disassemble or reassemble different types of gas sources with the same intake assembly 51, making it convenient to use.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
