Description

Technical Field

[0001] This application relates to the field of pneumatic conveying system technology, and more specifically to an intelligent air replenishment valve. Background Technology

[0002] In existing gas delivery and pressure regulation systems, the gas replenishment valve plays a crucial role as a key component in maintaining system pressure stability. However, traditional gas replenishment valves have numerous structural and performance defects.

[0003] On the one hand, traditional air-replenishing valves typically employ complex piping connections between the inlet and pressure chamber. This connection not only increases the overall structural complexity of the valve but also lengthens the flow path of the pressurized gas. As the gas flows through this long pipeline, friction with the pipe walls is inevitable, leading to increased flow losses and reduced energy efficiency. Furthermore, the gas velocity in traditional air-replenishing valves is relatively low. When the gas velocity is insufficient, even small impurities, such as naturally occurring dust particles or debris from equipment wear, can easily accumulate and deposit in the outlet chamber, causing blockage. This blockage not only affects normal gas output but can also lead to pressure imbalances in the entire system, resulting in equipment malfunctions or even complete failure. Utility Model Content

[0004] The purpose of this application is to provide an intelligent gas replenishment valve to solve the problems of large pressure gas flow loss and easy blockage at the outlet chamber and the main delivery pipeline faced by existing gas replenishment valves.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: An intelligent gas replenishment valve is provided, comprising: an inlet chamber, a pressure chamber, and an outlet chamber. One end of the inlet chamber is connected to an inlet for the entry of pressurized gas. The other end of the inlet chamber is directly connected to the pressure chamber via a turbulent flow hole, and the pressure chamber is connected to the outlet for the exit of pressurized gas. The valve also includes a solenoid valve and a pressure sensor. Another end of the inlet chamber is connected to the pressure chamber via the solenoid valve, and the pressure chamber is connected to the pressure sensor. The solenoid valve is circuitically connected to the pressure sensor, and the pressure sensor is used to detect the gas pressure within the pressure chamber. When the pressure within the pressure chamber rises, the solenoid valve opens, allowing a large amount of gas to flow into the pressure chamber through the solenoid valve and then to the outlet.

[0006] As a preferred embodiment, the turbulent flow hole is provided with a guide end face on the side near the air intake chamber.

[0007] As another preferred embodiment, the air intake chamber and the pressure chamber are located in the same axial direction and are directly connected through the turbulent flow hole.

[0008] Further preferably, a check valve is provided inside the outlet chamber to prevent backflow of the medium inside the outlet chamber.

[0009] Preferably, the solenoid valve and the pressure chamber are connected via a pneumatic pressure hose, and the pneumatic pressure hose is detachably connected to the solenoid valve via a first quick-connect plug.

[0010] Preferably, the pneumatic pressure hose is detachably connected to the pressure chamber via a second quick-connect plug.

[0011] Preferably, the main body of the pneumatic pressure hose is bent, and the bent portion is arc-shaped.

[0012] More preferably, the pressure sensor is connected to the upper left end of the pressure chamber, the pneumatic pressure hose is connected to the upper right end of the pressure chamber, the air outlet is connected to the middle of the pressure chamber, and the air outlet, the pressure sensor, and the pneumatic pressure hose are located on opposite sides of the pressure chamber.

[0013] Compared with the prior art, the beneficial effects of this application are as follows:

[0014] The intelligent gas replenishment valve provided in this application eliminates the need for piping between the inlet and pressure chambers through a direct connection, reducing the flow path of the pressurized gas and thus minimizing flow losses. Furthermore, the turbulent flow orifice increases the gas velocity as it enters the pressure chamber from the inlet. When the gas enters the pressure chamber at a higher velocity through the turbulent flow orifice, its kinetic energy increases significantly. In the structure connecting the pressure and outlet chambers, this high-speed airflow generates strong momentum, propelling the gas rapidly into the outlet chamber to reach the outlet, reducing the risk of blockage by foreign matter.

[0018] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0020] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0022] In a preferred embodiment, see Figures 1 to 2 This application provides an intelligent gas replenishment valve 1, including: an inlet chamber 10, a pressure chamber 20, and an outlet chamber 30. One end of the inlet chamber 10 is connected to an inlet for the entry of pressurized gas, and the other end of the inlet chamber 10 is directly connected to the pressure chamber 20 through a turbulent flow hole 40. The pressure chamber 20 is connected to the outlet for the exit of pressurized gas. It also includes a solenoid valve 50 and a pressure sensor 60. The other end of the inlet chamber 10 is connected to the pressure chamber 20 through the solenoid valve 50, and the pressure chamber 20 is connected to the pressure sensor 60. The solenoid valve 50 and the pressure sensor 60 are electrically connected. The pressure sensor 60 is used to detect the gas pressure in the pressure chamber 20. When the pressure in the pressure chamber 20 rises, the solenoid valve 50 opens, allowing a large amount of gas to flow into the pressure chamber 20 through the solenoid valve 50 and then to the outlet.

[0023] It should be noted that, in order to keep the pneumatic conveying system close to the "minimum" air consumption point, changes in coal type or problems with the dust collector may lead to the generation of coarse and heavy ash in the unit. Due to the low flow velocity between the silo pumps and at the beginning of the conveying section, ash-gas separation will occur, increasing the risk of pipe blockage. To achieve stable operation, a larger air volume is required, leading to increased energy consumption. Therefore, an air replenishment device, namely the intelligent air replenishment valve 1, should be installed between the silo pumps and at the beginning of the conveying section. This device achieves intelligent and digital control. Based on changes in pipeline pressure, the intelligent system control technology will promptly replenish air at the point where a material blockage is about to form, eliminating long material blocks and increasing the material flow velocity. This effectively addresses the problem of conveying coarse and heavy ash at the minimum air volume. It can also monitor pipeline pressure changes in real time, providing effective data support for the digital management of the system. This results in advantages such as low air consumption, less wear on ash pipes and valves, unmanned operation, and fully automatic operation of the entire system.

[0024] The intelligent gas replenishment valve 1 provided in this application eliminates the need for pipeline connection between the air inlet chamber 10 and the pressure chamber 20 by directly connecting the air inlet chamber 10 and the pressure chamber 20, thereby reducing the flow path of the pressurized gas and reducing the flow loss of the pressurized gas.

[0025] Furthermore, the presence of the turbulent flow orifice 40 increases the gas velocity as pressurized gas enters the pressure chamber 20 from the inlet chamber 10. Consequently, when gas enters the pressure chamber 20 at a higher velocity through the turbulent flow orifice 40, its kinetic energy increases significantly. In the structure connecting the pressure chamber 20 and the outlet chamber 30, this high-speed airflow generates strong momentum, propelling the gas rapidly into the outlet chamber 30 to reach the outlet. Therefore, from the perspective of preventing blockage, the higher gas velocity generated by the turbulent flow orifice 40 produces a powerful scouring force. Even if small impurities, such as dust particles or debris from the pipe, are present in the outlet chamber 30, the high-speed pressurized gas can quickly carry them out due to its strong impact force. This scouring effect is similar to how a rushing river washes away silt from a riverbed, ensuring that the outlet chamber 30 remains unobstructed. Compared to traditional gas delivery methods with lower flow rates, debris is less likely to deposit and accumulate in the outlet chamber 30 under the influence of high-speed airflow, thus preventing blockage.

[0026] Meanwhile, the presence of the turbulent flow orifice 40 creates a relatively stable gas channel between the inlet chamber 10 and the pressure chamber 20. When the gas pressure at the inlet fluctuates slightly, a small amount of gas can stably enter the pressure chamber 20 through the turbulent flow orifice 40. This intake method can buffer the pressure in the pressure chamber 20, preventing drastic pressure changes due to sudden pressure changes at the inlet, thus helping to maintain relative pressure stability within the pressure chamber 20. When gas enters the pressure chamber 20 through the turbulent flow orifice 40, turbulence occurs due to the orifice's structural characteristics. This turbulence allows the gas entering the pressure chamber 20 to mix better with the existing gas, resulting in more uniform gas composition and pressure throughout the pressure chamber 20.

[0027] In summary, the configuration of the turbulent flow orifice 40 provides a strong guarantee for the stable operation of the gas delivery system of the intelligent gas supply valve 1 in this application.

[0028] As a preferred embodiment, the turbulent flow hole 40 is provided with a guide end face 41 on the side near the intake chamber 10. Specifically, see... Figure 2 The guide end face 41 is a spindle-shaped structure. The guide end face 41 of the spindle-shaped structure can guide the gas. When the pressurized gas flows from the inlet chamber 10 to the turbulent flow hole 40, the spindle-shaped guide end face 41 can make the gas flow lines converge more smoothly into the turbulent flow hole 40. Like a dike in a river, it can guide the dispersed gas flow to a specific channel, reduce the turbulence and energy loss in the gas flow process, and enable the gas to enter the pressure chamber 20 more efficiently through the turbulent flow hole 40.

[0029] The guide face 41 reduces resistance to gas flow. Gas experiences less resistance as it flows through the guide face 41, allowing it to pass through the turbulent flow orifice 40 at a more ideal flow rate and pressure. This helps improve the overall efficiency of the intelligent gas supply valve 1. In a fluid system, reduced resistance means reduced energy loss and improved gas transmission performance.

[0030] The shape of the shuttle-shaped guide end face 41 makes it difficult for impurities to accumulate on its surface. During the gas flow process, some tiny impurity particles may be carried. The shuttle-shaped structure has no sharp corners or recesses, making it difficult for impurities to adhere. Even if a small amount of impurities come into contact with the guide end face 41, they will be more easily carried away by the scouring of the gas, thus keeping the guide end face 41 clean and ensuring that the air intake function of the turbulent flow hole 40 is not affected.

[0031] Before the gas enters the turbulent flow orifice 40, a relatively uniform pressure distribution is formed around the guide end face 41. This ensures that the gas flow rate through each turbulent flow orifice 40 is relatively consistent, thereby making the pressure distribution in the pressure chamber 20 more uniform, which is beneficial to improving the performance and stability of the intelligent gas replenishment valve 1.

[0032] Meanwhile, in other specific embodiments, the guide end face 41 can be processed into a teardrop-shaped streamlined end face according to actual usage requirements. The streamlined guide end face 41 is similar to a spindle shape, with a rounded front end, allowing gas to smoothly bypass the guide end face 41 and enter the turbulent flow hole 40. This shape can effectively reduce gas separation during flow, allowing the airflow to closely adhere to the guide end face 41. Under high-speed airflow conditions, the teardrop-shaped guide end face 41 can reduce air resistance better than other shapes because its shape design conforms to the natural streamline trajectory of fluid during high-speed flow. Alternatively, the guide end face 41 can be a more rounded parabolic end face. The parabolic guide end face 41 has good focusing characteristics. When gas approaches the guide end face 41, the parabolic shape can cause the gas to converge towards the central axis, thereby more effectively guiding the gas into the turbulent flow hole 40.

[0033] As another preferred option, the intake chamber 10 and the pressure chamber 20 are located in the same axial direction and are directly connected through the turbulent flow hole 40. The direct connection between the intake chamber 10 and the pressure chamber 20 in the same axial direction through the turbulent flow hole 40 makes the structure of the entire valve more compact and simple. This layout reduces unnecessary pipe connections, bends and turning parts, thereby reducing the complexity of the manufacturing process.

[0034] Meanwhile, the connection between the intake chamber 10 and the pressure chamber 20 is along the circumferential movement direction of the pressurized gas, which avoids the flow direction of the pressurized gas and thus effectively reduces the flow loss of the pressurized gas. The axial direct connection allows the pressurized gas to be transmitted more directly from the intake chamber 10 to the pressure chamber 20, improving the working efficiency of the entire intelligent air replenishment valve 1.

[0035] The uniaxial layout is more intuitive and convenient for maintenance personnel. When inspecting and maintaining the intelligent air supply valve 1, technicians can more easily understand the gas flow path and quickly locate the connection between the intake chamber 10 and the pressure chamber 20, including the turbulent flow orifice 40. In case of faults such as abnormal pressure, this simple and direct structure helps to quickly determine whether the problem lies in the intake chamber 10, the pressure chamber 20, or the connection between them, thereby improving the efficiency of troubleshooting.

[0036] Furthermore, the circumferential straight connection means that the gas is less affected by external interference factors as it enters the pressure chamber 20 from the inlet chamber 10. For example, phenomena such as secondary flow and vortex caused by pipe bends are greatly reduced, which helps to maintain the flow stability of the pressurized gas.

[0037] Further preferably, a check valve 70 is provided inside the outlet chamber 30 to prevent backflow of the medium inside the outlet chamber 30.

[0038] Preferably, the solenoid valve 50 and the pressure chamber 20 are connected via a pneumatic pressure hose 80, and the pneumatic pressure hose 80 is detachably connected to the solenoid valve 50 via a first quick-connect plug 81. Specifically, the pneumatic pressure hose 80 is a PU tube with good bending and ductility. Preferably, the pneumatic pressure hose 80 is also detachably connected to the pressure chamber 20 via a second quick-connect plug 82. The first quick-connect plug 81 and the second quick-connect plug 82 facilitate the replacement of the pneumatic pressure hose 80.

[0039] Preferably, the body of the pneumatic pressure hose 80 is bent, and the bent part is arc-shaped, which reduces the gas collision loss when the pressurized gas passes through the pneumatic pressure hose 80, so that the pressurized gas can enter the pressure chamber 20 more smoothly from the pneumatic pressure hose 80.

[0040] Further optimization, with Figure 1 As shown in the figure, pressure sensor 60 is connected to the upper left end of pressure chamber 20, pneumatic pressure hose 80 is connected to the upper right end of pressure chamber 20, and air outlet 30 is connected to the middle of pressure chamber 20. Air outlet 30, pressure sensor 60, and pneumatic pressure hose 80 are located on opposite sides of pressure chamber 20.

[0041] Compared to the configuration where the outlet chamber 30 is biased towards the pressure sensor 60 or the pneumatic pressure hose 80, the outlet chamber 30 in this application is located in the middle of the pressure chamber 20, that is, between the pneumatic pressure hose 80 and the pressure sensor 60. For different batches of gas entering the pressure chamber 20, such as gas entering through the pneumatic pressure hose 80 and gas entering through the turbulent flow orifice 40, the central location of the outlet chamber 30 helps to promote gas mixing. When gas enters the pressure chamber 20 from the inlet chamber 10, it has more opportunities to be fully mixed during its flow towards the central outlet chamber 30, resulting in a more uniform composition and quality of the gas flowing out of the outlet chamber 30.

[0042] In a specific operating procedure, when pressurized gas enters through the inlet, the intelligent gas replenishment valve 1 operates normally. At this time, the solenoid valve 50 is closed, and the pressurized gas can only enter the pressure chamber 20 through the turbulent flow orifice 40. Then, the pressurized gas in the pressure chamber 20 passes through the valve flap of the check valve 70 and enters the main delivery pipeline through the outlet. At this time, the flow direction of the pressurized gas is along the attached... Figure 1 The flow is from direction X1 to direction X2 to direction X3. The function of check valve 70 is to prevent the medium in the conveying pipeline from flowing back.

[0043] When the main conveying pipeline becomes congested or experiences a material plug, the pressure in the main conveying pipeline will inevitably increase. This prevents the gas in pressure chamber 20 from being discharged into the main conveying pipeline in a timely manner through the outlet. As a result, the air pressure in pressure chamber 20 will rise. Pressure sensor 60 will detect this signal in time, forcing solenoid valve 50 to open. A large flow of pressurized gas will then enter the main conveying pipeline through solenoid valve 50, pneumatic pressure hose 80, pressure chamber 20, and check valve 70 to forcibly flush the material plug at the congestion point, thereby eliminating the pipeline congestion and restoring smooth conveying. At this time, the flow direction of the pressurized gas is along the attached... Figure 1 The flow proceeds from direction X1 to direction X4 to direction X5 to direction X3.
