[0002] Stainless steel flange is a common pipe connector, widely used in pipeline systems in the petroleum, chemical, electric power, shipbuilding, pharmaceutical, food and other industries. It is mainly used to connect two pipe sections, or to connect pipelines to valves, pumps and other equipment for easy installation, disassembly and maintenance. The material of stainless steel flange is usually stainless steel, such as 304, 316, 321 and other stainless steel grades. These materials have good corrosion resistance, high temperature resistance and mechanical strength, and can adapt to various harsh working environments. Stainless steel flanges have various structural forms, including flat welding flanges, butt welding flanges, blind flanges, threaded flanges, loose flanges, etc. Each type has its specific application occasions and connection methods. As an important pipeline connector, the performance and quality of stainless steel flanges directly affect the safe operation and service life of the entire pipeline system. Therefore, when selecting and using stainless steel flanges, it is necessary to fully consider factors such as its material, structure, manufacturing process and application environment;

[0003] At present, the sealing components inside the flange are prone to aging after long-term use during use, which can easily cause leakage in the flange. Currently, there is no direct emergency treatment for flange leakage, and the leaked liquid directly falls to the ground. Utility Model Content

[0004] The purpose of the utility model is to provide a stainless steel flange with good sealing performance, so as to solve the problem raised in the above-mentioned background technology that the sealing components inside the flange are prone to aging during long-term use during use, which easily causes the flange to leak. At present, emergency treatment cannot be directly made for flange leakage, and the leaked liquid directly falls to the ground.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stainless steel flange with good sealing performance, comprising a first flange and a second flange, the second flange being arranged on the right side of the first flange, characterized in that a first buckle plate is fitted on the outer wall of the second flange, a second buckle plate is fitted on the outer wall of the first flange, and the inner sides of the first buckle plate and the second buckle plate are fitted together, a rubber sleeve is arranged inside the fitting part of the first buckle plate and the second buckle plate, an observation window is arranged inside the left side of the second buckle plate, the inner parts of the first buckle plate and the second buckle plate are both threadedly arranged on the outer wall of the bolt, and a drainage assembly is arranged at the bottom end of the second buckle plate.

[0006] Preferably, a plurality of groups of threaded holes are equidistantly provided inside the first gusset plate and the second gusset plate.

[0007] Preferably, the observation window is made of transparent acrylic material.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model is arranged that when the stainless steel flange with good sealing performance is put into use, the first buckle plate, the second buckle plate and the rubber sleeve are used in combination to achieve emergency treatment when the flange leaks. By using the observation window, it is possible to observe whether the flange is leaking through the observation window during daily maintenance. By using the plug block and the rubber ring in combination, it is possible to discharge the liquid after the flange leaks. The coordinated use of the above-mentioned structure solves the problem that the flange cannot be treated on the left side in an emergency when leaking, causing the leaked liquid to fall directly on the ground.
