Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a cooling water tank flange. Background Art

[0002] Flange, also known as flange flange or flange; flange is a part that connects shafts to each other and is used to connect pipe ends; flanges are also used on equipment inlets and outlets to connect two devices, such as reducer flanges; flange connection or flange joint refers to a detachable connection in which flanges, gaskets and bolts are connected to each other as a combined sealing structure.

[0003] Pipe flange refers to the flange used for piping in pipeline installations. When used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal the flanges. Flanges are divided into threaded (threaded) flanges, welding flanges and clamp flanges. Flanges are used in pairs. Threaded flanges can be used for low-pressure pipelines, and welding flanges can be used for pressures above four kilograms. Sealing gaskets are added between the two flanges and then tightened with bolts. Flanges of different pressures have different thicknesses, and the bolts they use are also different. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes. , also known as flange connection; any connection parts that are bolted and closed around two planes are generally called "flanges", such as the connection of ventilation ducts, this type of parts can be called "flange parts"; but this connection is only a part of a device, such as the connection between a flange and a water pump, it is not appropriate to call the water pump a "flange part"; smaller ones such as valves can be called "flange parts", and flanges are often needed for connection in vacuum tube furnaces, but the temperature of the flange near the vacuum tube furnace is too high, which can easily cause the flange sealing ring to fail, and then cause the vacuum pipeline to leak, thus affecting its use;

[0004] Some fluid media flowing through pipelines often reach relatively high temperatures, and the high temperature resistance requirements for flanges are very high. In order to make the flanges work normally even under high temperature fluids, people often change the material of the flanges to meet the high temperature resistance effect, but this results in excessively high costs and cannot meet customer needs.

[0012] The flange body is provided with a water outlet pipe corresponding to the fourth annular water groove. The water outlet pipe enters the flange body radially from the outer periphery of the flange body, then extends axially from the flange body to the outside of the fourth annular water groove, and then is connected with the fourth annular water groove radially from the flange body.

[0013] In order to form a good sealing structure and make the coolant flow in a certain direction, a further preferred technical solution is that a circle of sealing grooves are respectively provided on the cooling water jackets on both sides of the first annular water groove, and sealing rings are provided in the sealing grooves;
