Description

Technical Field

[0001] This invention relates to the field of butterfly valve technology, and in particular to a novel high-temperature resistant butterfly valve. Background Technology

[0002] A butterfly valve, also known as a flap valve, is a simple regulating valve. Its unique design—a disc-shaped closing element (valve disc or butterfly plate) that rotates around the valve shaft—makes it an important shut-off and throttling device in pipeline systems. The main characteristics of a butterfly valve are low operating torque, small installation space, light weight, and ease of integration with various drive devices, exhibiting good durability and reliability. Its simple structure, consisting of only a few components such as the valve body, valve stem, butterfly plate, and sealing ring, makes installation and maintenance relatively convenient.

[0003] During the search process for this application, the applicant discovered a Chinese patent disclosing a "high-temperature resistant and wear-resistant butterfly valve," application number "201320126383." This patent primarily utilizes a heat-insulating sleeve structure to isolate the valve cavity from the entire valve body through a cavity, preventing the high-temperature medium inside the valve cavity from easily transferring heat outwards, thus improving the high-temperature resistance of the invention. Reinforcing plates increase the strength of the heat-insulating sleeve, and connecting plates increase the strength of the two annular side plates, improving the service life of the invention. The alumina ceramic layer achieves high-temperature resistance and wear resistance. However, the cavity inside the heat-insulating sleeve structure of this device can easily lead to uneven heating, thus posing a safety hazard. Therefore, we propose a novel high-temperature resistant butterfly valve to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a novel high-temperature resistant butterfly valve, comprising a connecting disc, with connecting buckles fixedly connected to the outer surface of the connecting disc, the connecting buckles being symmetrically distributed on both sides of the outer surface of the connecting disc, a fixing bolt penetrating through the center of one side of the outer surface of the connecting buckle, multiple fixing bolts penetrating through one side of the outer surface of the connecting disc, a butterfly valve main ring penetrating through the center of one side of the outer surface of the connecting disc, the inner surface of the butterfly valve main ring being uniformly coated with a high-temperature resistant chemical coating, a sealing plate assembly penetrating through the middle of the upper surface of the butterfly valve main ring, the sealing plate assembly being movably connected to one side inside the connecting disc, a rotating component being rotatably connected to the top of the sealing plate assembly, the sealing plate assembly comprising a sealing plate outer shell, a sealing plate heat insulation outer jacket, heat insulation material filler, a sealing plate heat insulation inner sleeve, and a sealing plate core, the sealing plate outer shell being movably connected to one side inside the connecting disc, the sealing plate outer shell being made of wear-resistant and high-temperature resistant metal material, the rotating component comprising a rotating shaft, a rotating block, a connecting main pipe, and a connecting rod, the rotating shaft being penetrating through the output end to the middle of the upper surface of the sealing plate assembly.

[0005] Preferably, the heat insulation outer jacket of the sealing plate is fixedly connected to the inner surface of the outer shell of the sealing plate, and the heat insulation material filler is located between the heat insulation outer jacket and the heat insulation inner jacket of the sealing plate.

[0006] Preferably, the heat-insulating inner sleeve of the sealing plate is fixedly connected to the outer surface of the core of the sealing plate, and the core of the sealing plate is fixedly connected to the center position inside the outer shell of the sealing plate.

[0007] Preferably, the rotating block is fixedly connected to one side of the upper surface of the rotating shaft, and the connecting main pipe is connected through the center of the outer surface of the rotating block.

[0008] Preferably, the connecting rod is fixedly connected to one side of the outer surface of the rotating block, and there are multiple connecting rods, which are symmetrically distributed on both sides of the outer surface of the rotating block.

[0009] The beneficial effects of this invention are: The sealing plate assembly not only enhances the sealing effect but also effectively reduces the thermal impact of high-temperature media on the valve body, improving the butterfly valve's high-temperature resistance and service life. The design of the rotating assembly greatly enhances the ease of operation of the butterfly valve. Through the cooperation of the rotating shaft, rotating block, connecting main pipe, and connecting rod, the operator can easily control the rotation amplitude of the sealing plate assembly, thereby achieving precise regulation of the material flow rate in the pipeline.

A butterfly valve main ring 4 penetrates the center of one side of the outer surface of the connecting disc 1. The inner surface of the butterfly valve main ring 4 is uniformly coated with a high-temperature resistant chemical coating. A sealing plate assembly 5 penetrates the center of the upper surface of the butterfly valve main ring 4. The sealing plate assembly 5 is movably connected to one side inside the connecting disc 1. A rotating assembly 6 is rotatably connected to the top of the sealing plate assembly 5.

The sealing plate core 505 and the sealing plate outer shell 501 are movably connected to one side of the connecting plate 1. The sealing plate outer shell 501 is made of wear-resistant and high-temperature resistant metal. The sealing plate heat insulation jacket 502 is fixedly connected to the inner surface of the sealing plate outer shell 501. The heat insulation material filler 503 is located between the sealing plate heat insulation jacket 502 and the sealing plate heat insulation inner sleeve 504. The sealing plate heat insulation inner sleeve 504 is fixedly connected to the outer surface of the sealing plate core 505. The sealing plate core 505 is fixedly connected to the center of the sealing plate outer shell 501. By setting the sealing plate assembly, the temperature of the high-temperature medium in the valve cavity can be allowed to overflow, improving the high-temperature resistance. The wear-resistant and high-temperature resistant metal sealing plate outer shell ensures the stable operation of the butterfly valve under harsh working conditions, reducing maintenance costs and the occurrence of safety accidents.
