[0011] The double-layered sealing strip better adapts to temperature changes, ensuring more stable sealing performance and preventing gas or fluid leakage. The wear-resistant coating and filter plate design not only increase the flange's durability but also filter impurities, ensuring that fluids or gases are not contaminated. The wear-resistant coating uses a zinc-plated coating, which effectively prevents friction and corrosion, extends the flange's service life, and reduces the frequency of maintenance and replacement, which is especially important for pipeline systems used for extended periods of time and under high intensity. The design of the external fixing components ensures that the flange will not loosen or fall off under high pressure or vibration environments. The bolts ensure a stable and reliable connection between the flange and the pipeline system, while the sealing plug prevents external substances or gases from entering the flange connection, ensuring that the gas or fluid inside the system is not disturbed by external factors, maintaining the system's sealing and cleanliness. Through the precise design of each component, flange installation is simpler, the connection is more secure, and stability and safety are guaranteed during long-term operation. The combined effect of sealing performance and fixing structure prevents leakage and loosening at the connection, improving the overall system's reliability and safety. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figure 1-3The present invention provides an embodiment of a stainless steel flange, comprising a fixing ring 1, a fixing hole 2, a connecting tube 3, a sealing plug 4, and an external fixing component 5. The fixing hole 2 is disposed around the surface of the fixing ring 1. The connecting tube 3 is disposed on the inner side of the fixing ring 1. The sealing plug 4 is connected to the inner side of the outer side of the fixing ring 1. The external fixing component 5 is disposed on the outer side of the fixing ring 1.

[0018] The connecting tube 3 includes a sealing strip 301, a wear-resistant coating 302, and a filter plate 303. The sealing strip 301 is provided on the inner side of the fixing ring 1, and the front end of the sealing strip 301 is connected to the wear-resistant coating 302. The filter plate 303 is provided on the inner side of the wear-resistant coating 302. It stably connects the flange to the pipeline system, provides stronger sealing capability, and ensures that the gas or fluid at the connection does not leak.

[0019] The sealing strip 301 has two layers: the wear-resistant layer 302 is a zinc-plated coating, and the filter plate 303 has a filter element to form a tight sealing interface with the connecting pipe to prevent fluid or gas leakage.

[0020] The fixing component 5 includes a connecting ring 501, a plug rod 502, and a bolt 503. The connecting ring 501 is provided on the outside of the fixing ring 1, and the plug rod 502 is installed on the inside of the connecting ring 501. The bolt 503 is installed at the tail end of the plug rod 502 to ensure a firm connection between the connecting ring 501 and the fixing ring 1 and to prevent loosening or falling off during use.

[0021] The inner wall of the connecting ring 501 matches the outer wall of the plug rod 502. The connecting ring 501 forms a fixed structure with the bolt 503 through the plug rod 502. The function of the plug rod 502 is to connect the connecting ring 501 and the fixing ring 1, while ensuring the stability of the connection.

[0022] Working principle: First, before installation, the connecting pipes and flanges need to be cleaned to ensure that there is no oil, dust or other impurities, so as to ensure the sealing and connection stability. The function of the connecting pipe 3 is to connect the flange to the piping system. The sealing strip is set inside the fixing ring 1. Since the sealing strip has two layers, it can better adapt to temperature changes and provide more stable sealing performance. The wear-resistant coating is a zinc-plated coating that protects the connecting pipe from friction and corrosion and extends its service life. The function of the filter plate is to prevent impurities from passing through the connecting pipe and ensure that the flow of fluid or gas in the system is not contaminated. The sealing plug 4 is installed inside the outside of the fixing ring 1 to prevent any external substances or gases from entering the flange connection. The sealing plug helps ensure the system's tightness and prevents leakage. During installation, it is essential to ensure the sealing plug is properly installed to prevent external factors from affecting the seal and causing it to fail. The external fixing assembly 5 securely fixes the flange to the piping system. The connecting ring 501 is installed outside the fixing ring 1, and its inner wall matches the outer wall of the plug rod 502. Through the connection with the plug rod 502, a robust structure is formed. The tail end of the plug rod 502 is fitted with a bolt 503. The tightening action of the bolt ensures that the connecting ring and the flange are reliably fixed. The plug rod 502 is fixed to the connecting ring 501 by the bolt 503, providing the necessary connection force to ensure a secure connection between the flange and the pipeline and prevent loosening under high pressure or vibration.
