Description

Technical Field

[0001] The utility model relates to the technical field of connecting flanges, in particular to a high-temperature and high-pressure corrosion-resistant pressing type connecting flange. Background Art

[0002] The compression flange is a reliable and economical way to connect pipes, which is widely used in industry and construction. This connection method is suitable for a variety of media and working conditions, and plays an important role in the pipeline system. The compression flange usually consists of two connecting parts: a clamp and a flange. The clamp is a part of the pipeline, usually made of metal, with high strength and corrosion resistance. The flange is a ring-shaped component made of reinforced materials, and common materials include carbon steel, stainless steel and plastic. There are usually bolt holes on the flange for fixing the connecting parts and sealing gaskets, so pipeline installers often need to use compression flanges in their daily work.

[0003] The existing compression type connection flange has the following disadvantages:

[0004] In the manufacturing process of the existing connection flange, the whole carbon steel is welded and the pre-processed steel pipe is overlapped and welded to the top surface of the base. This causes the welding part to be prone to cracks when it is used for too long, resulting in damage to the entire connection flange and affecting work efficiency.

[0005] During the use of some connecting flanges, when high-temperature materials are transported inside the connecting flanges, the internal sealing rings are prone to deformation, resulting in poor sealing between the connecting flanges and external pipe fittings, affecting the use of the connecting flanges. Utility Model Content

[0006] The technical problem solved by the utility model is to provide a high-practicality, high-temperature, high-pressure, corrosion-resistant, compressed connecting flange with a relatively simple structure and simple operation. The utility model solves the problem that the existing connecting flanges proposed in the above background technology are made of integral carbon steel for welding during the manufacturing process, and the pre-processed steel pipes are overlapped and welded to the top surface of the base, which causes cracks to easily form at the welding points when used for too long, causing damage to the entire connecting flange and affecting work efficiency. During the use of some connecting flanges, when high-temperature materials are transported inside the connecting flange, the internal sealing rings are easily deformed, resulting in poor sealing between the connecting flange and the external pipe fittings, affecting the use of the connecting flange.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a high-temperature, high-pressure, corrosion-resistant compression-type connecting flange, comprising a base, a reinforcement ring is fixedly connected to the inside of the base, a steel pipe is clamped to the inside of the reinforcement ring, a welding strip is fixedly connected to the edge of the top surface of the reinforcement ring, a groove is opened on one side of the inner wall of the steel pipe, a high-temperature resistant sealing ring is fixedly connected to the inside of the groove, a metal ring is sleeved on the inside of the high-temperature resistant sealing ring, and a high-temperature resistant cylinder is embedded in the steel pipe.

[0008] Optionally, the outer surface of the steel pipe is equidistantly fixedly connected with stabilizing blocks in a circular array, and the top surface of the base is equidistantly provided with circular grooves in a circular array. The stability between the steel pipe and the base is enhanced through the structural design of the stabilizing blocks.

[0009] Optionally, the outer surface of the steel pipe is provided with an anti-corrosion coating, the material of the anti-corrosion coating is epoxy resin, and the corrosion resistance of the steel pipe is improved by providing the anti-corrosion coating.

[0010] Optionally, reinforcing ribs are provided inside the base, and an arc ring is fixedly connected to one side of the surface of the steel pipe. The provision of the arc ring improves the firmness of the steel pipe.

[0011] Optionally, the steel pipe is made of titanium alloy, and a sealing ring is fixedly connected to the bottom of the reinforcement ring. The provision of the sealing ring improves the sealing performance of the connection between the base and the external device.

[0012] Optionally, an anti-oxidation coating is attached to the outer surface of the arc ring, and the arc ring is arranged in a conical shape. The anti-oxidation coating improves the oxidation resistance of the arc ring.

[0013] The utility model provides a high temperature and high pressure corrosion resistant clamping type connecting flange, which has the following beneficial effects:

[0014] 1. The high-temperature and high-pressure corrosion-resistant compression connection flange is provided with a reinforcement ring, a steel pipe, a welding strip and a base. When processing personnel process the connection flange, they can insert the steel pipe into the gap between the reinforcement ring and the base. The processing personnel can use external equipment to weld the welding strip to connect the reinforcement base and the steel pipe, thereby improving the stability of the connection flange.

[0015] 2. The high-temperature and high-pressure corrosion-resistant compression connecting flange, through the arrangement of metal rings, high-temperature resistant sealing rings and steel pipes, can allow staff to plug external equipment into the steel pipe when using the connecting flange, and the high-temperature resistant sealing ring fits tightly with the metal ring and the outer surface of the external pipe fitting, thereby improving the sealing performance of the connection between the steel pipe and the external pipe fitting, and increasing the service life of the high-temperature resistant sealing ring, making it difficult for the high-temperature resistant sealing ring to deform under the limitation of the metal ring.
