Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic controller valves, in particular to a pneumatic pressure controller valve. Background Art

[0002] Pneumatic pressure controller valve is an important device for regulating gas flow and maintaining system pressure stability. It consists of key components such as valve body, valve disc, valve seat and operating device, and remote or automatic control of the valve is achieved through pneumatic actuator. This type of valve is widely used in industrial automation systems, process control systems, and hydraulic and pneumatic systems to ensure safe transportation and stable operation of gas in pipelines. Its working principle is to open, close or adjust the valve disc through the operating device to adjust the flow and pressure of the medium to meet the needs of the system.

[0003] Traditional pneumatic pressure controller valves are key components in fluid control systems, mainly composed of valve body, valve cover, valve disc, valve seat, valve stem and operating device. The valve body is the main part of the valve, containing fluid channels and connecting the inlet and outlet of the pipeline system. The valve cover is located on the top of the valve body, closing the valve body and fixing the valve disc, and is often connected by threads or bolts for maintenance. The valve disc is the core of controlling the flow of the medium, sealing the valve seat to prevent leakage and allowing the medium to flow through when opened. The valve seat is located inside the valve body and is made of wear-resistant material to ensure sealing. The valve stem connects the valve disc and the handle or operating device to control the opening and closing of the valve and regulate the flow of the medium. The pneumatic actuator, as an operating device, receives control system signals and adjusts the valve position to control flow and pressure. The valve may also include auxiliary components such as seals, connectors and regulating devices to ensure its normal operation and reliability. These components together constitute the structure of the pneumatic pressure controller valve, providing a reliable solution for industrial fluid control.

[0004] However, the structure of the valve flap mechanism in the traditional pneumatic pressure controller valve is relatively simple, mainly composed of circular or quasi-circular valve flaps. This simple structure has some potential problems. First, due to the limitation of the valve flap shape, its ability to control flow may be limited, especially in applications that require precise flow control, such as chemical industry or precision manufacturing. Secondly, the single valve flap structure may have insufficient adaptability when dealing with different media or working conditions, and cannot be flexibly adjusted to meet different process requirements. In addition, due to the limitations of the single valve flap structure, the performance of the valve may be unstable or the reliability is not high, which increases maintenance and operating costs. Therefore, expanding the valve flap mechanism and adopting a more complex design or a combination of multiple valve flaps can improve the flexibility and performance of the valve, ensure its stable operation under various working conditions, and thus better meet the needs of industrial fluid control. For this reason, a pneumatic pressure controller valve is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a pneumatic pressure controller valve, including a support plate 19, a second L-shaped plate 17 is fixedly connected to the side wall of the support plate 19, a first L-shaped plate 16 is fixedly connected to the side wall of the second L-shaped plate 17, a connecting column 20 is fixedly connected inside the support plate 19, a rotor 18 is fixedly connected to one end of the connecting column 20, a support block 21 is fixedly connected to the outer wall of the connecting column 20, a hollow disk 4 is fixedly connected to the bottom of the support block 21, a hollow ball 22 is rotatably connected inside the hollow disk 4, a sealing ring 24 is fixedly connected inside the hollow disk 4, a fixing component is arranged on the outer wall of the hollow disk 4, the fixing component includes a threaded block 23, and the side wall of the threaded block 23 is fixedly connected to the outer wall of the hollow disk 4.

[0032] Specifically, the connection column 20 is driven to rotate by the rotation of the rotor 18, and the connection column 20 is located inside the support plate 19. The rotation of the connection column 20 acts on the hollow ball 22 at the bottom, causing it to start rotating. The hollow ball 22 is located inside the hollow disk 4, and the hollow disk 4 is fixed inside the sealing ring 24. The purpose of liquid sealing is achieved and liquid leakage is prevented. Therefore, the rotation of the rotor 18 is transmitted to the hollow ball 22 through the connection column 20, and then a reliable seal is formed between the hollow disk 4 and the sealing ring 24, ensuring the sealing performance of the system, which can effectively prevent liquid leakage and improve the reliability and safety of the system.

[0033] Reference Figure 1 and Figure 2 The top of the rotor 18 is fixedly connected to a fixed column 10, the outer wall of the fixed column 10 is fixedly connected to a fixed column 10, the outer wall of the fixed column 10 is fixedly connected to a hollow block 2, the top of the hollow block 2 is fixedly connected to a support plate 7, the top of the fixed column 10 is fixedly connected to a turntable 1, the inside of the hollow block 2 is slidably connected to a sliding plate 12, the side wall of the sliding plate 12 is fixedly connected to a rack 8, the side wall of the rack 8 is fixedly connected to a stopper 11, the rack 8 is meshed with a gear 9, the inside of the hollow block 2 is fixedly connected to a connecting pipe 14, the inside of the connecting pipe 14 is fixedly connected to a gas pipe 15, one end of the gas pipe 15 is fixedly connected to a gas tank 3, the outer wall of the gas tank 3 is fixedly connected to a fixing ring 6, the side wall of the hollow block 2 is fixedly connected to a connecting block 5, and the side wall of the connecting block 5 is fixedly connected to a fixing ring 6.

[0034] Specifically, when using the pneumatic pressure controller valve, gas is first injected from the gas tank 3 into the hollow block 2 through the gas pipe 15, and the pressure applied thereby pushes the gap between the stopper 11 and the sliding plate 12, causing the sliding plate 12 to start moving. This movement causes the rack 8 to move, which in turn drives the gear 9 on the side wall to rotate. As the gear 9 rotates, the internal fixed column 10 also rotates. This complex mechanism design realizes the control of the bottom rotor 18.

[0035] Reference Figure 2 A spring 13 is provided on the side wall of the sliding plate 12 , and the other end of the spring 13 is fixedly connected to the inside of the hollow block 2 .

[0036] Specifically, in the system, the sliding plate 12 is subjected to the dual effects of the pressure applied by the gas through the hollow block 2 and the side wall spring 13. The spring 13 provides additional force when the sliding plate 12 moves, and applies a contraction force to the sliding plate 12 when necessary. When the gas pressure no longer acts on the hollow block 2, the spring 13 begins to contract, pushing the sliding plate 12 back to the initial position, thereby effectively realizing the reset of the sliding plate 12. The side wall spring 13 plays a key role in the system, not only providing additional force, but also ensuring the reliability and stability of the system under specific circumstances.

[0037] Working principle: When using a pneumatic pressure controller valve, first, the gas is blown into the interior of the hollow block 2 through the gas tank 3 through the gas pipe 15 and then through the connecting pipe 14. At the same time, the gas is blown into the interior of the hollow block 2. At the same time, the force of the hollow block 2 pushes the gap between the stopper 11 and the sliding plate 12. At the same time, the movement of the sliding plate 12 drives the rack 8 on one side to move. At the same time, the movement of the rack 8 drives the gear 9 on the side wall to rotate. At the same time, the rotation of the gear 9 drives the internal fixed column 10 to rotate, thereby achieving the effect of controlling the rotation of the bottom rotor 18, and the spring 13 on the force-bearing side wall of the sliding plate 12 contracts, achieving the effect of contracting the spring 13. Next, the connecting column 20 is driven to rotate through the rotation of the rotor 18, and the connecting column 20 rotates inside the support plate 19. The rotation of the connecting column 20 drives the hollow ball 22 at the bottom to rotate, and the hollow ball 22 rotates inside the hollow disk 4, and the inside of the hollow disk 4 is fixed inside the sealing ring 24, thereby achieving the effect of preventing liquid leakage.
