Description

Technical Field

[0001] This utility model belongs to the field of valve technology and relates to an air intake valve assembly with a bracket. Background Technology

[0002] Currently, most gas extraction valves on the market lack real-time monitoring capabilities for parameters such as pressure during the gas extraction process. When abnormalities occur during extraction, such as sudden pressure changes or gas leaks, they cannot be detected and addressed promptly, posing certain safety hazards. Furthermore, the monitoring components of existing gas extraction valves are mostly integrated structures; if a malfunction occurs, the entire assembly must be replaced, resulting in high maintenance costs and a significant financial burden on users. Therefore, there is an urgent need for a gas extraction valve assembly with a bracket that can monitor the gas extraction process in real time, possesses self-diagnostic capabilities, and is easy to maintain and replace.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a car cylinder air intake valve [application number: CN03254700.5], which consists of an air inlet, an air outlet, and a one-way valve. The one-way valve is located between the air inlet and the air outlet. The air inlet has an external thread for connecting to the car cylinder spark plug, and the air outlet is connected to the air guide pipe. When using this invention, the spark plug on one of the engine cylinders is removed, and the air intake valve is installed on the car cylinder spark plug. The air intake valve is sealed to the car cylinder through the external thread at the air inlet. When the engine is started, the air intake valve can inflate the tires through the air outlet and the air guide pipe. However, this solution still cannot detect and handle abnormal situations in a timely manner during the air intake process, and it has the drawback of high installation and maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems by providing an air intake valve assembly with a bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air intake valve assembly with a bracket includes a valve body, characterized in that the valve body has an air inlet and an air outlet, a connecting channel is provided between the air inlet and the air outlet, a monitoring installation space is provided at the end of the connecting channel away from the air inlet, an integrated elastic pressure structure is installed in the monitoring installation space, a sealing bracket cover is provided on the top of the valve body, a monitoring element is provided in the sealing bracket cover, and the integrated elastic pressure structure is positioned opposite to the monitoring element.

[0007] In the aforementioned air intake valve assembly with bracket, the integrated elastic pressure structure includes a fixed socket disposed in the monitoring installation space, a first spring disposed between the fixed socket and the valve body, and a pressure-bearing slide rod disposed inside the fixed socket that can reciprocate in a straight line, the pressure-bearing slide rod being disposed opposite to the monitoring component, and the pressure-bearing slide rod and the first spring being disposed alternately.

[0008] In the aforementioned air intake valve assembly with bracket, the bottom of the pressure-bearing slide rod is provided with an enlarged platform. The cross-section of the enlarged platform is circular, and the cross-sectional area of ​​the enlarged platform is larger than the cross-sectional area of ​​the pressure-bearing slide rod. The pressure-bearing slide rod is slidably engaged with the fixed socket.

[0009] In the aforementioned air intake valve assembly with bracket, a second spring is provided on the pressure-bearing slide rod, and a supporting step surface is provided in the monitoring installation space. The top of the first spring is sleeved on the bottom of the fixed socket, and the bottom abuts against the supporting step surface.

[0010] In the aforementioned air intake valve assembly with bracket, the monitoring components include a pressure sensor and a micro MCU disposed on the inner wall of the sealed bracket cover, with the pressure sensor facing the pressure-bearing slide rod.

[0011] In the aforementioned air intake valve assembly with bracket, the sealing bracket cover is provided with a slide rod anti-deviation alignment component, which slides in cooperation with the pressure-bearing slide rod.

[0012] In the aforementioned air intake valve assembly with bracket, the slide rod anti-deviation alignment component includes an anti-deviation frame body disposed within the sealing bracket cover. The anti-deviation frame body is in the shape of a hollow cone, and the pressure-bearing slide rod passes through the anti-deviation frame body and slides in cooperation with the anti-deviation frame body.

[0013] In the aforementioned air intake valve assembly with bracket, the internal thread of the sealing bracket cover is screwed into the external thread of the valve body.

[0014] In the aforementioned air intake valve assembly with bracket, a sealing ring is provided between the fixed socket and the inner wall of the valve body.

[0015] In the aforementioned air intake valve assembly with bracket, a downwardly recessed flow channel surface is formed between the air outlet and the connecting channel.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. In the gas extraction process of this utility model, gas enters the connecting channel through the air inlet, and the pressure acts on the pressure-bearing slide rod in the integrated elastic pressure structure. The pressure-bearing slide rod transmits the pressure to the pressure sensor in the opposite monitoring component. The pressure sensor converts the pressure signal into an electrical signal and transmits it to the micro MCU. The micro MCU analyzes and processes the signal to realize real-time monitoring of the pressure during the gas extraction stage. When the pressure data is abnormal, such as exceeding the preset normal range, the micro MCU can determine that there is a fault in the gas extraction process and promptly trigger self-diagnostic functions such as alarms to remind the user to take corresponding measures to avoid safety accidents.

[0018] 2. In this utility model, the monitoring component is housed within the sealing bracket cover. The sealing bracket cover is screwed to the external thread of the valve body via internal threads, forming a detachable, split structure. When the monitoring component malfunctions, it can be repaired or replaced simply by unscrewing the sealing bracket cover, without disassembling the entire air intake valve assembly. This significantly reduces repair difficulty and cost, and improves repair efficiency.

[0019] 3. In the integrated elastic pressure structure of this utility model, the first spring and the second spring provide stable elastic support for the pressure-bearing slide rod, ensuring that it can accurately transmit pressure to the monitoring device under pressure. The enlarged platform at the bottom of the pressure-bearing slide rod increases the contact area with the gas, making the pressure transmission more stable. The anti-deviation frame in the slide rod anti-deviation alignment component can effectively prevent the pressure-bearing slide rod from shifting during reciprocating motion, ensuring the accuracy of pressure transmission and improving the stability and reliability of the entire gas intake valve assembly.

[0020] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-3 As shown, an air intake valve assembly with a bracket includes a valve body 1, which has an air inlet 2 and an air outlet 3. The assembly is characterized by a connecting channel 4 between the air inlet 2 and the air outlet 3, a monitoring installation space 5 at the end of the connecting channel 4 away from the air inlet 2, an integrated elastic pressure structure 6 installed within the monitoring installation space 5, a sealing bracket cover 7 on the top of the valve body 1, and a monitoring element 8 inside the sealing bracket cover 7. The integrated elastic pressure structure 6 and the monitoring element 8 are positioned opposite each other.

[0027] In this embodiment, the valve body 1 serves as the basic structure of the gas intake valve assembly. Internally, it is machined to form an air inlet 2, an air outlet 3, and a connecting channel 4. A monitoring installation space 5 is located at the end of the connecting channel 4 furthest from the air inlet 2, providing an installation position for the integrated elastic pressure structure 6. The sealing bracket cover 7 is screwed to the external thread on the top of the valve body 1 via internal threads to achieve a sealed connection, while also providing installation space for the monitoring component 8. The integrated elastic pressure structure 6 and the monitoring component 8 are positioned opposite each other, ensuring that during the gas intake process, the gas pressure can be accurately transmitted to the monitoring component 8 through the integrated elastic pressure structure 6, enabling real-time monitoring. This structure designs the monitoring component 8 and the valve body 1 as detachable separate units, facilitating subsequent maintenance and replacement of the monitoring component 8 and reducing costs. Simultaneously, the cooperation between the integrated elastic pressure structure 6 and the monitoring component 8 enables real-time monitoring and self-diagnosis of the gas intake stage.

[0028] Combination Figure 1-3 As shown, the integrated elastic pressure structure 6 includes a fixed socket 9 disposed in the monitoring installation space 5. A first spring 10 is provided between the fixed socket 9 and the valve body 1. A pressure-bearing slide rod 11 that can reciprocate in a straight line is provided in the fixed socket 9. The pressure-bearing slide rod 11 is disposed opposite to the monitoring component 8. The pressure-bearing slide rod 11 and the first spring 10 are arranged alternately.

[0029] Specifically, the pressure-bearing slide rod 11 is installed inside the fixed socket 9 and slides in conjunction with the fixed socket 9. It is also staggered with the first spring 10, so that under the action of gas pressure, the pressure-bearing slide rod 11 can reciprocate in a straight line and transmit the pressure to the monitoring element 8 directly opposite. This structure, through the cooperation of the first spring 10 and the fixed socket 9, ensures that the pressure-bearing slide rod 11 can stably transmit pressure under the action of pressure, thereby improving the accuracy of pressure monitoring.

[0030] The bottom of the pressure-bearing slide rod 11 is provided with an enlarged platform 12. The cross-section of the enlarged platform 12 is circular, and the cross-sectional area of ​​the enlarged platform 12 is larger than the cross-sectional area of ​​the pressure-bearing slide rod 11. The pressure-bearing slide rod 11 is slidably engaged with the fixed socket 9.

[0031] In this embodiment, the expanded platform 12 at the bottom of the pressure-bearing slide rod 11 has a circular cross-section and a cross-sectional area larger than that of the pressure-bearing slide rod 11, which increases the contact area with the gas. Under the action of gas pressure, the expanded platform 12 can more effectively transmit pressure to the pressure-bearing slide rod 11, making the movement of the pressure-bearing slide rod 11 more stable, and further improving the accuracy and stability of pressure monitoring.

[0032] Combination Figure 3 As shown, the pressure-bearing slide bar 11 is provided with a second spring 13, and the monitoring installation space 5 is provided with a supporting step surface 14. The top of the first spring 10 is sleeved on the bottom of the fixed socket 9, and the bottom abuts against the supporting step surface 14.

[0033] In this embodiment, the second spring 13 is sleeved on the pressure-bearing slide rod 11, and together with the first spring 10, it provides elastic support for the pressure-bearing slide rod 11. When gas pressure acts on the pressure-bearing slide rod 11, the pressure-bearing slide rod 11 compresses the second spring 13 and moves upward. When the gas pressure decreases, the second spring 13 and the first spring 10 work together to reset the pressure-bearing slide rod 11, ensuring that the pressure-bearing slide rod 11 can accurately reciprocate when the pressure changes, and continuously transmit the pressure signal to the monitoring device 8.

[0034] The monitoring component 8 includes a pressure sensor 15 and a micro MCU 16 disposed on the inner wall of the sealing bracket cover 7, with the pressure sensor 15 being positioned opposite the pressure-bearing slide bar 11.

[0035] In this embodiment, the pressure sensor 15 is installed on the inner wall of the sealing bracket cover 7, directly opposite the pressure-bearing slide rod 11. It can accurately receive the pressure signal transmitted by the pressure-bearing slide rod 11 and convert it into an electrical signal. The micro MCU 16 is electrically connected to the pressure sensor 15, analyzes and processes the electrical signal transmitted by the pressure sensor 15, and determines whether the pressure data during the gas extraction process is normal. When the pressure data is abnormal, the micro MCU 16 triggers the corresponding alarm or other self-diagnostic functions to realize real-time monitoring and fault diagnosis of the gas extraction process. Those skilled in the art should understand that the pressure sensor 15 and the micro MCU 16 are prior art, and their internal structure and working principle are not the focus of this patent, so they will not be described in detail. At the same time, the micro MCU 16 can output through the CAN bus and can be electrically connected to external electrical components or alarm devices.

[0036] Combination Figure 3As shown, the sealing bracket cover 7 is provided with a sliding rod anti-deviation alignment component 17, which is in sliding cooperation with the pressure-bearing sliding rod 11.

[0037] In this embodiment, during the reciprocating motion of the pressure slide bar 11, the slide bar anti-deviation alignment member 17 can limit the movement trajectory of the pressure slide bar 11, prevent it from deviating, and ensure that the pressure slide bar 11 can accurately transmit pressure to the pressure sensor 15, thereby improving the accuracy and stability of pressure monitoring.

[0038] The sliding rod anti-deviation alignment component 17 includes an anti-deviation frame 18 disposed within the sealing bracket cover 7. The anti-deviation frame 18 is in the shape of a hollow cone, and the pressure-bearing sliding rod 11 passes through the anti-deviation frame 18 and slides in cooperation with the anti-deviation frame 18.

[0039] In this embodiment, the hollow cone-shaped anti-deviation frame 18 can limit and guide the pressure slide rod 11 from multiple directions during its movement, effectively preventing the pressure slide rod 11 from deviating and ensuring the accuracy of pressure transmission.

[0040] Combination Figure 1-3 As shown, the internal thread of the sealing bracket cover 7 is screwed into the external thread of the valve body 1.

[0041] In this embodiment, the internal thread of the sealing bracket cover 7 is screwed into the external thread of the valve body 1. This connection method not only achieves a tight connection between the sealing bracket cover 7 and the valve body 1, ensuring the sealing performance of the gas valve assembly and preventing gas leakage; at the same time, when it is necessary to repair or replace the monitoring component 8, the sealing bracket cover 7 can be easily and quickly disassembled and installed, demonstrating the advantages of the detachable split structure.

[0042] Combination Figure 3 As shown, a sealing ring 19 is provided between the fixed socket 9 and the inner wall of the valve body 1.

[0043] In this embodiment, the sealing ring 19 is disposed between the fixed socket 9 and the inner wall of the valve body 1, which further enhances the sealing between the fixed socket 9 and the valve body 1, prevents gas from leaking from the connection between the fixed socket 9 and the valve body 1, and ensures the safety and accuracy of the gas intake process.

[0044] Combination Figure 3 As shown, a downwardly recessed flow channel surface 20 is formed between the air outlet 3 and the connecting channel 4.

[0045] In this embodiment, the downwardly recessed flow channel surface 20 formed between the gas outlet 3 and the connecting channel 4 alters the gas flow path. As the gas flows from the connecting channel 4 to the gas outlet 3, the flow channel surface 20 guides the gas to flow more smoothly, reducing gas flow resistance, improving gas flow efficiency, and making the gas extraction process more stable and efficient.

[0046] The working principle of this utility model is as follows:

[0047] When the gas valve is working, gas enters the connecting channel 4 inside the valve body 1 from the gas inlet 2. As the gas flows, pressure is applied to the expansion platform 12 at the bottom of the pressure-receiving slide rod 11. Under the action of pressure, the pressure-receiving slide rod 11 overcomes the elastic force of the second spring 13 and moves upward. At the same time, it drives the fixed socket 9 to compress the first spring 10. During the upward movement of the pressure-receiving slide rod 11, its top transmits the pressure to the pressure sensor 15 directly opposite it.

[0048] The pressure sensor 15 converts the received pressure signal into an electrical signal and transmits it to the micro MCU 16. The micro MCU 16 analyzes and processes the electrical signal and compares it with the preset normal pressure range. If the pressure data is within the normal range, the gas extraction process proceeds normally. If the pressure data exceeds the normal range, the micro MCU 16 determines that the gas extraction process is abnormal, triggers the corresponding alarm device or takes other self-diagnostic measures to remind the user to check and handle the situation.

[0049] When the gas pressure decreases, the pressure-bearing slide bar 11 and the fixed socket 9 are reset under the elastic force of the first spring 10 and the second spring 13, waiting for the monitoring of the next pressure change. During the reciprocating motion of the pressure-bearing slide bar 11, the anti-deviation frame 18 limits and guides the pressure-bearing slide bar 11 to prevent it from deviating and ensure the accuracy of pressure transmission.

[0050] When the monitoring component 8 needs to be repaired or replaced, simply unscrew the sealing bracket cover 7. Since the sealing bracket cover 7 is connected to the valve body 1 by threads, disassembly is convenient and quick. Then the monitoring component 8 inside the sealing bracket cover 7 can be repaired or replaced. After the repair is completed, screw the sealing bracket cover 7 back onto the valve body 1 to restore the normal use of the air intake valve assembly.

[0051] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.

[0052] Although this document frequently uses terms such as valve body 1, air inlet 2, air outlet 3, connecting channel 4, monitoring installation space 5, integrated elastic pressure structure 6, sealing bracket cover 7, monitoring component 8, fixed socket 9, first spring 10, pressure-bearing slide rod 11, expansion platform 12, second spring 13, supporting step surface 14, pressure sensor 15, micro MCU 16, slide rod anti-deviation alignment component 17, anti-deviation frame 18, sealing ring 19, flow channel surface 20, etc., the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
