Description

Technical Field

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

[0002] Pneumatic valves are devices that use compressed air as a power source and control the opening and closing of valves through pneumatic actuators, thereby achieving automatic control of the flow of media in pipelines (such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media, etc.). Pneumatic valves are widely used in the industrial field and are favored for their fast response speed, high control accuracy, easy installation and good safety.

[0003] In the prior art, many pneumatic valves rely on the opening and closing of pistons and air holes to control the flow and stop of the medium. However, piston-type pneumatic valves can usually only provide discrete open or closed states and cannot provide continuous flow regulation. This may not be ideal for applications that require precise flow control, limiting the flexibility of operation and the reliability of the system.

[0004] Therefore, those skilled in the art provide a novel pneumatic valve to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a new type of pneumatic valve. When the valve is in use, the connecting rod is driven to move by the arranged cylinder so that the multiple grooves inside the conical block are accurately aligned with the multiple protrusions inside the conical tube, thereby achieving a smooth fit between the grooves and the protrusions and accurately controlling the size of the gap between them, thereby accurately controlling the flow of the fluid through the valve, significantly improving the flexibility of operation and the reliability of the system. At the same time, the large contact area between the conical block and the conical tube can withstand higher pressure, ensuring the reliability and safety of the valve in a high-pressure environment.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel pneumatic valve comprises a pipeline, a cylinder is arranged on one side of the outer wall of the pipeline, a connecting block is fixedly connected to one end of the cylinder, a connecting rod is fixedly connected to one side of one end face of the connecting block, a conical block is fixedly connected to one side end face of the connecting rod, grooves are evenly spaced on the outer wall of the conical block, a conical cylinder is fixedly connected to the lower end of the inner part of the pipeline, convex blocks are evenly spaced and fixedly connected to the inner part of the conical cylinder, an anti-corrosion layer is arranged on the inner wall of the pipeline, an insulating layer is arranged on the inner middle part of the pipeline, and an anti-oxidation layer is arranged on the outer wall of the pipeline;

[0008] Through the above technical solution, when the valve is in use, the connecting rod is driven to move by the arranged cylinder, so that the multiple grooves inside the conical block are accurately aligned with the multiple protrusions inside the conical tube, thereby achieving a smooth fit between the grooves and the protrusions, and accurately controlling the size of the gap between them, so as to accurately control the flow of the fluid through the valve, significantly improving the flexibility of operation and the reliability of the system, and at the same time, the large contact area between the conical block and the conical tube can withstand higher pressure, ensuring the reliability and safety of the valve in a high-pressure environment.

[0009] Further, the conical block is slidably connected to the pipeline;

[0010] Through the above technical solution, the sliding connection can ensure the stability of the conical block during movement, thereby ensuring the stability of the flow rate.

[0011] Furthermore, through holes are evenly spaced apart inside and outside the conical block;

[0012] Through the above technical solution, the presence of the through holes can ensure that the medium can flow evenly through the grooves on each conical block, which helps to ensure that the grooves on the conical blocks can be fully utilized and avoid problems such as medium accumulation in certain areas or uneven flow rate.

[0013] Furthermore, flanges are fixedly connected to one side of both ends of the outer wall of the pipeline;

[0014] Through the above technical solution, the flange is reliably fastened and is not prone to loosening or leakage, thereby ensuring the operational stability of the pipeline system.

[0015] Furthermore, the anti-corrosion layer is made of polyurethane material;

[0016] Through the above technical solution, polyurethane has excellent chemical corrosion resistance, can effectively protect the inner wall of the pipeline, prevent corrosion, and extend the service life of the pipeline.

[0017] Further, the thermal insulation layer is made of mineral wool material;

[0018] Through the above technical solution, mineral wool has a lower thermal conductivity, which can effectively isolate the heat transfer inside and outside the pipeline, reduce heat loss, help improve the energy efficiency of the pipeline, and save energy consumption.

[0019] Furthermore, the anti-oxidation layer is made of metallic zinc material;

[0020] Through the above technical solution, metallic zinc can physically and chemically combine with the surface of the pipeline to form a solid protective film, thereby effectively preventing the pipeline surface from being corroded and extending the service life of the pipeline.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a new type of pneumatic valve. Compared with the existing pneumatic valve, when the pneumatic valve is used, the connecting rod is driven to move by the provided cylinder, so that the multiple grooves inside the conical block are accurately aligned with the multiple protrusions inside the conical tube, so as to achieve a smooth fit between the grooves and the protrusions, and accurately control the size of the gap between them, so as to accurately control the flow of the fluid through the valve, significantly improving the flexibility of operation and the reliability of the system. At the same time, the large contact area between the conical block and the conical tube can withstand higher pressure, ensuring the reliability and safety of the valve in a high-pressure environment.

[0023] 2. The utility model proposes a new type of pneumatic valve. Compared with the existing pneumatic valves, the pneumatic valve can prevent the medium in the pipeline from corroding the metal material on the inner wall of the pipeline, protect the metal material on the surface of the pipeline from oxidation, and reduce the transfer between the medium in the pipeline and the external temperature, thereby maintaining the temperature of the medium in the pipeline stable, helping to reduce the probability of accidents in the pipeline system, improve the safety and reliability of the pipeline system, and extend the service life of the pipeline.

When the valve is in use, the connecting rod 5 is driven to move by the provided cylinder 3, so that the multiple grooves 9 inside the conical block 6 and the multiple protrusions 10 inside the conical tube 7 are accurately aligned, thereby achieving a smooth fit between the grooves 9 and the protrusions 10, and accurately controlling the size of the gap between them, so as to accurately control the flow of the fluid through the valve, significantly improving the flexibility of operation and the reliability of the system. At the same time, the large contact area between the conical block 6 and the conical tube 7 can withstand higher pressure, ensuring the reliability and safety of the valve under high pressure environment.

[0033] The conical block 6 is slidably connected to the pipeline 1.

Flanges 2 are fixedly connected to one side of both ends of the outer wall of the pipeline 1.
