Description

Technical Field

[0001] The present invention relates to the technical field of gas valves, and in particular to a gas valve pressure stabilizing device and an assembly method thereof. Background Art

[0002] As a key component in gas delivery and control systems, intake valves are widely used in various industrial and civilian applications. Their primary function is to precisely regulate the amount of gas entering the system, ensuring that the gas pressure and flow rate within the system remain within a set range to meet diverse process and production requirements. Traditional intake valves use a mechanical structure to open and close the gas flow, effectively performing their function under standard pressure conditions.

[0003] However, in real-world applications, gas pressure is not always stable. When encountering high-pressure gas, the structural characteristics of traditional intake valves prevent them from providing timely buffering. This high pressure instantly exerts a significant impact on the valve core, causing rapid movement and even abnormal vibration. This not only affects the accuracy of gas flow control and causes system pressure fluctuations to exceed allowable limits, but can also accelerate wear of intake valve components, reducing their service life, increasing equipment maintenance costs, and increasing the risk of downtime. Summary of the Invention

[0004] Based on this, in order to solve the problem that the structural characteristics of the traditional intake valve make it unable to be buffered in time when encountering high-pressure gas, one of the objectives of the present invention is to provide a valve pressure stabilizing device, the specific technical solution of which is as follows: A gas valve pressure-stabilizing device comprises a first mounting member, a second mounting member and a pressure-stabilizing structure, wherein the first mounting member and the second mounting member are detachably connected; the pressure-stabilizing structure is installed between the first mounting member and the second mounting member, and the pressure-stabilizing structure comprises an air inlet member and an elastic member, one end of the elastic member abuts against the inner wall of the first mounting member, and the end of the elastic member away from the first mounting member abuts against the air inlet member; the air inlet member comprises a bottom plate, a side wall and a vent pipe, the bottom plate is fixedly connected to the side wall, the vent pipe is arranged on the axial end surface of the bottom plate and fixedly connected to the bottom plate, the side wall extends in a direction away from the vent pipe, the bottom plate and the vent pipe are fixedly connected, and the end of the elastic member away from the first mounting member abuts against the axial end surface of the bottom plate.

[0005] Compared with the prior art, the gas valve pressure stabilizing device of the present invention has the following beneficial effects: by providing a first mounting member and a second mounting member, a stable installation foundation is provided for the pressure stabilizing structure, and the detachable connection between the first mounting member and the second mounting member makes the installation and maintenance of the entire device more convenient and quick, while ensuring the structural stability of the entire device. The pressure stabilizing structure is installed between the first mounting member and the second mounting member, and can accurately play its pressure stabilizing role, ensuring that the gas flows smoothly in the device, and the relative positions between the various components are fixed, which is conducive to achieving a stable gas pressure regulation function. By providing a pressure stabilizing structure, the pressure stabilizing structure includes an air inlet member and an elastic member, and the elastic member has elastic support and pressure regulation functions. When strong air pressure is passed into the pressurized air inlet member, the air inlet member applies pressure to the elastic member, and the elastic member is compressed and generates elastic force. As the gas pressure increases, the elastic part is further compressed and the elastic force increases accordingly, thereby preventing the air intake part from continuing to move rapidly. Due to the buffering effect of the elastic part, the movement of the air intake part is precisely controlled and will not occur excessively or abnormally due to strong air pressure. The gas can pass through the gas valve pressure stabilizing device at a predetermined flow rate and pressure, ensuring that the pressure in the system is stable within the allowable range, thereby improving the accuracy of gas flow control.

[0006] In some embodiments, the pressure stabilizing structure includes a sealing ring, which is arranged between the elastic member and the base plate. The sealing ring is sleeved on the outside of the ventilation tube and tightly abuts against the axial end face of the base plate away from the side wall, and the end of the elastic member close to the base plate is tightly abutted against the sealing ring.

[0009] In some embodiments, a plurality of exhaust notches are provided on the side wall, and each exhaust notch is distributed at an edge of the side wall.

The first accommodating hole, the first air hole, and the second accommodating hole are connected in sequence. The radius of the first accommodating hole is respectively larger than the radius of the first air hole and the second accommodating hole, and the radius of the second accommodating hole is larger than the radius of the first air hole.

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments.

[0019] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 2The diagram schematically shows a gas valve pressure stabilizing device according to an embodiment of the present invention, comprising a first mounting member 1, a second mounting member 2 and a pressure stabilizing structure 3. The first mounting member 1 is detachably connected to the second mounting member 2. By providing the first mounting member 1 and the second mounting member 2, a stable mounting base is provided for the pressure stabilizing structure 3. The detachable connection between the first mounting member 1 and the second mounting member 2 makes the installation and maintenance of the entire device more convenient and quick, while ensuring the structural stability of the entire device. The pressure stabilizing structure 3 is installed between the first mounting member 1 and the second mounting member 2, and can accurately play its pressure stabilizing role, ensuring that the gas flows smoothly in the device, and the relative positions between the various components are fixed, which is conducive to achieving a stable gas pressure regulation function. The pressure stabilizing structure 3 includes an air inlet member 31 and an elastic member 32. One end of the elastic member 32 abuts against the inner wall of the first mounting member 1, and the end of the elastic member 32 away from the first mounting member 1 abuts against the air inlet member 31. In this embodiment, the elastic member 32 is configured as a spring. The elastic member 32 plays a key role in the pressure-stabilizing structure 3, providing elastic support and regulating pressure. The elastic force of the elastic member 32 allows the air inlet member 31 to move within a certain range, thereby regulating the gas pressure and achieving a stable pressure. For example, if the incoming gas pressure exceeds the set value, the elastic member 32 can effectively absorb and disperse this excess energy through its own elastic deformation, thus providing a buffering and pressure-stabilizing effect. The elastic member 32 provides both elastic support and pressure-regulating functions. When strong gas pressure is applied to the air inlet member 31, the air inlet member 31 applies pressure to the elastic member 32, compressing it and generating an elastic force. As the gas pressure increases, the elastic member 32 compresses further, increasing the elastic force and thus preventing the air inlet member 31 from moving further rapidly. Thanks to the cushioning effect of the elastic member 32, the movement of the air inlet member 31 is precisely controlled, preventing excessive or abnormal movement due to high gas pressure. This allows gas to flow through the gas valve pressure-stabilizing device at the predetermined flow rate and pressure, ensuring that the pressure within the system remains stable within the allowable range and improving the accuracy of gas flow control.

[0022] like Figure 3As shown, the air inlet member 31 includes a base plate 311, a side wall 312, and a vent tube 313. The base plate 311 is fixedly connected to the side wall 312. The vent tube 313 is arranged on the axial end surface of the base plate 311 and is fixedly connected to the base plate 311. The side wall 312 extends away from the vent tube 313, guiding the flow of gas. The base plate 311 and the vent tube 313 are fixedly connected. In this embodiment, the base plate 311 is configured as a circular plate, and the side wall 312 is arranged on the circumference of the base plate 311. The base plate 311, side wall 312, and vent tube 313 are integrally formed, making the structure of the air inlet member 31 more stable, effectively reducing the risk of air leakage caused by loose connection parts, thereby improving the reliability of the entire device and extending its service life. The end of the elastic member 32 away from the first mounting member 1 abuts against the axial end surface of the base plate 311, so that the elastic member 32 can accurately apply elastic force and ensure the stability of the direction of the elastic force, thereby better realizing elastic support and adjustment of the air inlet member 31.

[0023] like Figure 2 As shown, in this embodiment, the pressure stabilizing structure 3 includes a sealing ring 33, which is arranged between the elastic member 32 and the bottom plate 311. The additional sealing ring 33 can be placed on the outside of the vent pipe 313 and tightly abut the axial end face of the bottom plate 311 away from the side wall 312. The end of the elastic member 32 close to the bottom plate 311 is tightly abutted against the sealing ring 33. Specifically, the air inlet member 31 can apply pressure to the elastic member 32, which is compressed and generates an elastic force. When the gas pressure increases, the elastic member 32 is further compressed, and the elastic force increases, thereby preventing the air inlet member 31 from continuing to move, acting as a buffer. When the gas pressure decreases, the elastic force of the elastic member 32 pushes the air inlet member 31 outward to maintain a certain pressure. Through this dynamic balancing adjustment, the elastic member 32 can effectively stabilize the gas pressure, ensuring that the output gas pressure remains within a set range. For example, if the set gas pressure is 5000 Pa and the incoming gas pressure is 5500 Pa, the elastic member 32 can effectively reduce the pressure to 5000 Pa. The main function of the sealing ring 33 in this embodiment is to prevent gas leakage. When the incoming gas pressure is too high, the air inlet member 31 moves toward the first mounting member 1 and abuts against the inner sidewall of the first mounting member 1. At this time, the sealing ring 33 can abut against the inner sidewall of the first mounting member 1 to achieve a full seal, ensuring that the gas can only flow within the set vent tube 313. At the same time, the elastic material of the sealing ring 33 also provides a certain buffering effect, reducing friction and wear between the air inlet member 31 and the elastic member 32, thereby extending the service life of the device. It should be noted that during assembly, the elastic member 32 needs to be accurately placed between the air inlet member 31 and the first mounting member 1 to ensure that it can properly perform its elastic support and pressure regulation functions.

[0024] like Figure 4 As shown, specifically, in this embodiment, the end of the vent tube 313 near the bottom plate 311 is provided with an air inlet 3131, and the end of the vent tube 313 away from the bottom plate 311 is provided with an air outlet 3132. The air inlet 3131 and the air outlet 3132 are connected to form a channel for gas circulation. The sealing ring 33 is mounted on the outside of the vent tube 313 and is tightly abutted against the bottom plate 311. The vent tube 313 is located in the center of the bottom plate 311, which facilitates uniform gas circulation, allowing gas to smoothly enter and exit the air inlet member 31. At the same time, it can ensure that the elastic member 32 is always located in the center of the air inlet member 31, ensuring uniform force when the gas presses the air inlet member 31.

[0025] like Figure 4 As shown, the end of the vent tube 313 away from the base plate 311 is tapered, with the angle of the tapered portion being set at 110°-130°. In this embodiment, the angle of the tapered portion is preferably 120°. On the one hand, this allows the gas to be more concentrated when it flows out of the vent tube 313, reducing gas diffusion at the outlet and improving gas transmission efficiency. On the other hand, the tapered structure can guide the flow direction of the gas, allowing the gas to enter the subsequent gas path system at a more stable flow rate and direction, helping to maintain the stability of the gas pressure within the entire device. The radius of the gas outlet 3132 is smaller than the radius of the gas inlet 3131. In this embodiment, the radius of the gas outlet 3132 is 0.5 mm, and the radius of the gas inlet 3131 is 2 mm. According to the principles of fluid mechanics, under a constant gas flow rate, the smaller the cross-sectional area, the greater the flow rate. Therefore, the gas can achieve a higher flow rate when it flows out of the gas outlet 3132.

[0026] like Figure 3 As shown, the side wall 312 is provided with a plurality of exhaust notches 3121, each of which is evenly distributed on the side wall 312. In this embodiment, two exhaust notches 3121 are provided, and they are arranged symmetrically. When the airflow is too strong, a portion of the airflow can be discharged through the exhaust notches 3121. The two symmetrically arranged exhaust notches 3121 can simultaneously and evenly blow the airflow toward the elastic member 32, preventing the elastic member 32 from shaking due to uneven force, and effectively ensuring that the elastic member 32 is always centered on the bottom plate 311. When the internal pressure of the air valve pressure stabilizing device is too high, the gas can be quickly discharged through these exhaust notches 3121, which acts to disperse the gas and effectively prevent the air intake member 31 from being damaged due to pressure accumulation. In addition, in other embodiments, the number and size of the exhaust gaps 3121 can be flexibly adjusted for different application scenarios. For example, in some scenarios where higher gas discharge speed requirements are required, the number of exhaust gaps 3121 can be appropriately increased or their sizes can be increased; and in scenarios where stricter gas leakage control requirements are required, the number of exhaust gaps 3121 can be reduced or their sizes can be reduced to meet different actual needs.

[0027] like Figure 5 As shown, the first mounting member 1 includes a first mounting seat 11, a first connecting seat 12, and a second mounting seat 13. The first mounting seat 11, the first connecting seat 12, and the second mounting seat 13 are fixedly connected in sequence, making the first mounting member 1 more flexible during the manufacturing and installation process. Each part can be processed separately according to actual needs and then assembled, thereby improving production efficiency and product quality. At the same time, the fixed connection between each part ensures the overall structural stability of the first mounting member 1. The second mounting seat 13 is detachably connected to the second mounting member 2. The voltage stabilizing structure 3 is installed between the second mounting seat 13 and the second mounting member 2. The end of the elastic member 32 away from the air inlet member 31 abuts against the first connecting seat 12, and the air inlet member 31 can abut against the second mounting seat 13. Figure 7 As shown, the second mounting member 2 includes a third mounting seat 21, a second connecting seat 22 and a fourth mounting seat 23. The third mounting seat 21, the second connecting seat 22 and the fourth mounting seat 23 are fixedly connected in sequence, similar to the first mounting member 1, which improves the flexibility of manufacturing and installation, and is conducive to ensuring the quality and precision of each part. At the same time, the overall structural stability of the second mounting member 2 is ensured through the fixed connection. The third mounting seat 21 is detachably connected to the first mounting member 1, and the voltage stabilizing structure 3 is installed between the third mounting seat 21 and the first mounting member 1. In this embodiment, the first mounting seat 11, the first connecting seat 12 and the second mounting seat 13 can be fixedly connected together in sequence by welding or integral molding, and the third mounting seat 21, the second connecting seat 22 and the fourth mounting seat 23 can also be fixedly connected together in sequence by welding or integral molding. The first mounting seat 11 and the third mounting seat 21 are both provided with internal threads, and the second mounting seat 13 and the fourth mounting seat 23 are both provided with external threads. The external threads in the second mounting seat 13 can engage with the internal threads of the third mounting seat 21 to play a fixing role. The first mounting seat 11 and the fourth mounting seat 23 can be threadedly connected to the external components respectively.

[0028] like Figure 6As shown, a first accommodating hole 111 is provided in the first mounting seat 11, and the first accommodating hole 111 provides a certain space for the circulation of gas in the device. A first air hole 121 is provided in the first connecting seat 12, and the first air hole 121 is an important channel for the circulation of gas inside the first mounting member 1. It connects the first accommodating hole 111 and the second accommodating hole 131, so that the gas can pass through these three holes in sequence. The size design of the first air hole 121 needs to comprehensively consider the flow rate and pressure requirements of the gas to ensure that the gas can pass through at an appropriate flow rate and pressure. A second accommodating hole 131 is provided in the second mounting seat 13. The second accommodating hole 131 not only provides space for the circulation of gas, but also provides a reference for the installation and positioning of the voltage stabilizing structure 3, ensuring that the voltage stabilizing structure 3 can be accurately installed between the first mounting member 1 and the second mounting member 2 to play its pressure stabilizing role. The first accommodating hole 111, the first air hole 121 and the second accommodating hole 131 are connected in sequence. The radius of the first accommodating hole 111 is respectively larger than the radius of the first air hole 121 and the second accommodating hole 131, and the radius of the second accommodating hole 131 is larger than the radius of the first air hole 121. The reasonable aperture size design in the first mounting member 1 enables the gas to circulate smoothly in the device, while providing a stable installation foundation for the voltage stabilizing structure 3 and other components. In this embodiment, the inner diameter of the elastic member 32 is larger than the diameter of the first air hole 121, the diameter of the second receiving hole 131 is larger than the inner diameter of the elastic member 32, the radius of the bottom plate 311 is equal to the radius of the second receiving hole 131, and the bottom plate 311 can abut against the side inner wall of the second receiving hole 131.

[0029] like Figure 8As shown, a third accommodating hole 211 is provided in the third mounting seat 21. The third accommodating hole 211 is an important channel for gas to enter the second mounting member 2. A second air hole 221 is provided in the second connecting seat 22. The second air hole 221 corresponds to the first air hole 121 and together constitute the main channel for gas to circulate in the device. The dimensions of the second air hole 221 must be precisely calculated based on the gas flow and pressure requirements to ensure that gas can pass through at a stable flow rate and pressure. A fourth receiving hole 231 is defined within the fourth mounting seat 23. This not only provides space for gas circulation but also serves as a reference for the installation and positioning of the pressure-stabilizing structure 3, ensuring that the pressure-stabilizing structure 3 is accurately installed between the first mounting member 1 and the second mounting member 2 to maximize its pressure-stabilizing function. The third receiving hole 211, the second air hole 221, and the fourth receiving hole 231 are sequentially connected. The radius of the third receiving hole 211 is greater than that of the second air hole 221, which in turn is greater than that of the fourth receiving hole 231. This radius is also greater than that of the second air hole 221. This facilitates the initial convergence and guidance of gas, allowing it to smoothly enter the second air hole 221. The structural design of the second mounting member 2 matches that of the first mounting member 1, ensuring smooth gas flow within the device and the overall structural stability of the device. The detachable connection design makes the installation and maintenance of the device more convenient and quick, and improves the efficiency and reliability of the device.

[0030] In this embodiment, the overall working principle of the air valve pressure stabilizing device is as follows: First, the fourth mounting seat 23 is connected to the external gas source to allow the required gas to pass into the device. During the process of gas introduction, the gas pressure continues to act on the axial end face of the bottom plate 311 close to the side wall 312, and a part of the gas begins to enter the air inlet 3131 of the vent pipe 313. The gas flows along the internal channel of the vent pipe 313 and flows out from the air outlet 3132. At the same time, if the gas flow is too much, the excess gas can be discharged in time through the exhaust gap 3121 to avoid abnormal pressure increase in the system and ensure the safe and stable operation of the device. As the gas pressure increases, the air intake member 31 will be pushed to move in the direction of the elastic member 32. At this time, the elastic member 32 is compressed and generates a reverse elastic force, which forms a dynamic balance with the gas pressure. As the air intake member 31 moves axially in the direction close to the second mounting seat 13 in the third mounting seat 21, the compression amount of the elastic member 32 continues to change. As shown in FIG. Figure 9As shown, as the gas pressure increases further, the displacement of the air inlet member 31 increases, the compression of the elastic member 32 intensifies, and the resulting reverse elastic force increases accordingly. At this point, the air inlet member 31 enters the second receiving hole 131 of the second mounting seat 13 and abuts against the inner wall of the second receiving hole 131. The sealing ring 33 also abuts tightly against the inner wall of the second receiving hole 131, forcing gas to flow out only through the outlet 3132 of the vent tube 313. By limiting the displacement of the air inlet member 31, the gas flow rate is suppressed, thereby gradually reducing the gas pressure. Conversely, when the gas pressure falls below the set value, the elastic force of the elastic member 32 pushes the air inlet member 31 back to its initial position. Through this dynamic adjustment process, when the system reaches a steady state, the air inlet member 31 ultimately stabilizes at a certain equilibrium position within the second receiving hole 131 due to the interaction between the elastic force of the elastic member 32 and the gas pressure. At this point, the gas pressure is precisely controlled within a preset range, achieving a stable pressure. The pressure stabilizing structure 3 can accurately control the gas pressure through the coordinated work of the air inlet member 31, the elastic member 32 and the sealing ring 33, ensuring that the pressure of the output gas is stable and reliable. At the same time, its reasonable structural design also improves the airtightness, safety and service life of the device.

[0031] like Figure 10 As shown, this embodiment also provides an assembly method for a gas valve pressure stabilizing device, which is applied to the above-mentioned gas valve pressure stabilizing device. The specific steps are as follows: S1. Slide the elastic member 32 onto the air inlet member 31, ensuring that one end of the elastic member 32 is in close contact with the axial end face of the base plate 311. In S1, first slide the sealing ring 33 onto the vent tube 313 of the air inlet member 31. Before assembly, apply a thin layer of special lubricant to the surfaces of the sealing ring 33 and the vent tube 313. Then, use tweezers to slowly and evenly insert the sealing ring 33 into the designated position on the vent tube 313. During insertion, be careful to avoid twisting or flipping the sealing ring 33, ensuring that it fits tightly against the vent tube 313 without any looseness or gaps. After installation, gently rotate the sealing ring 33 by hand to check whether it can rotate freely and without any obstruction. Then, put the elastic member 32 on the vent tube 313 so that one end of the elastic member 32 is in close contact with the bottom plate 311. When putting the elastic member 32 on the vent tube 313, try to ensure that the axis of the elastic member 32 coincides with the axis of the vent tube 313 to avoid uneven force caused by tilted installation of the elastic member 32. Then, gently press the elastic member 32 by hand to check whether it can freely expand and contract without any abnormalities such as obstruction or excessive friction. If the elastic member 32 is not installed smoothly, check for impurities or mismatched component sizes and resolve them in a timely manner.

[0032] S2, place the air inlet member 31 and the elastic member 32 in the first mounting member 1, and make the end of the elastic member 32 away from the air inlet member 31 abut against the inner wall of the first mounting member 1. Figure 3、 Figure 7 As shown, in S2, the voltage stabilizing structure 3 is placed in the second accommodating hole 131 of the second mounting seat 13, and the end of the elastic member 32 away from the air inlet member 31 abuts against the axial end face of the first connecting seat 12. In this embodiment, the inner diameter of the elastic member 32 is greater than the diameter of the first air hole 121, the diameter of the second accommodating hole 131 is greater than the inner diameter of the elastic member 32, the radius of the bottom plate 311 is equal to the radius of the second accommodating hole 131, and the bottom plate 311 can abut against the side inner wall of the second accommodating hole 131.

[0033] S3. Place the end of the voltage-stabilizing structure 3 away from the first mounting member 1 within the second mounting member 2. Rotate the second mounting member 2 to securely connect the first and second mounting members 1 and 2. The end of the side wall 312 away from the base plate 311 abuts the axial end surface of the second connecting seat 22. In this embodiment, the first and second mounting members 1 and 2 are securely connected by the rotational connection of the second mounting seat 13 and the third mounting seat 21. It is also important to note that during installation, the force and speed of rotation must be carefully controlled to avoid excessive force that could damage components or overtighten the connection, potentially affecting subsequent disassembly and maintenance.

[0034] S4.
