Description

Technical Field

[0001] This utility model belongs to the field of flow divider manufacturing technology, specifically relating to a flow divider manufactured by a welding process. Background Technology

[0002] The flow divider is a crucial component in fluid systems, widely used in industries such as petroleum, chemical, and power. Traditional flow divider connections mostly employ bolted connections, which, despite their mature manufacturing process, have certain limitations. First, bolted connections require multiple parts, such as bolts, nuts, and washers, increasing material costs and assembly steps, leading to lower production efficiency. Second, stress concentration can occur at bolted joints, especially under high pressure or high temperature conditions, making them prone to loosening and leakage, affecting the flow divider's sealing and stability. More seriously, with increasing usage time, bolted connections may suffer fatigue damage, impacting the overall performance and lifespan of the equipment.

[0003] The existing flow divider has the following drawbacks:

[0004] 1. Complex structure: Traditional bolted connection requires the use of multiple components, such as bolts, nuts, and washers. This makes the manufacturing process of the flow divider more complex, increases the number of components and assembly steps, leading to increased production costs and extended production cycles. Therefore, there is an urgent need for a flow divider manufactured using a welding process. Summary of the Invention

[0005] The main objective of this invention is to provide a flow divider cavity manufactured by welding process, which can effectively solve the problems in the background art.

The flow divider cavity side plate is provided at the lower end of the flow divider cavity upper cover plate, the flow divider cavity lower cover plate is provided at the lower end of the flow divider cavity side plate, and the flow divider corner rib plate is provided on the inner side of the flow divider cavity side plate.

[0007] The upper cover plate of the diversion cavity is welded to the side frame and the inner diversion corner rib plate of the diversion cavity side plate. The lower end of the diversion cavity side plate has a bottom surface. The lower cover plate of the diversion cavity is welded to the bottom surface of the lower end of the diversion cavity side plate. The perforated plate of the diversion cavity is welded to the square hole of the lower cover plate of the diversion cavity. Welding is not allowed at the top of the four corners of the lower cover plate of the diversion cavity.

[0008] Furthermore, the welding material for the weld seams of the upper cover plate of the diversion cavity, the diversion corner rib plate, the diversion cavity side plate, the lower cover plate of the diversion cavity, and the diversion cavity orifice plate is ERNiCr-3.

[0009] Furthermore, the upper cover plate, side plate, lower cover plate, and orifice plate of the diversion cavity are fully penetrated by welds, and the diversion rib plate and upper cover plate of the diversion cavity are welded by spot welding.

[0010] Furthermore, the upper cover plate of the diversion cavity is machined to 4 mm, and the lower cover plate of the diversion cavity is machined to 3 mm.

[0011] This utility model has the following beneficial effects:

[0012] 1. This device simplifies the production process, reduces the number of parts, and lowers manufacturing costs by welding the various components of the flow divider chamber, offering the following benefits: Simplified Production Process: By employing welding, the various components of the flow divider chamber can be directly welded together, avoiding the additional parts (bolts, nuts, washers, etc.) required for traditional bolted connections, thus simplifying the production process. Complex assembly and fastening operations are eliminated, reducing manual intervention and increasing the degree of automation in production. Reduced Number of Parts: The welding process allows the connection parts of the flow divider chamber to no longer rely on multiple parts, but rather form a single integrated structure through direct welding. This not only reduces the number of parts that need to be procured and managed, but also lowers inventory and transportation costs. Lower Manufacturing Costs: Since no additional accessories are required during the welding process, and assembly, fastening, and inspection steps are reduced, the overall manufacturing cost is significantly lowered. Furthermore, the welding process itself is more advantageous in terms of material and labor costs compared to bolted connections, further improving economic efficiency. Attached Figure Description

[0029] The top cover of the flow divider chamber is located at the top of the flow divider chamber and serves to seal the interior of the chamber. Its lower end connects to the side plate of the flow divider chamber, providing upper sealing and support for the entire flow divider chamber.

[0030] Diverter stiffener: Located on the inner side of the diverter cavity side plate, it strengthens the diverter cavity structure, prevents the diverter cavity side plate from deforming due to stress, and ensures the stability of the structure.

[0031] The side plate of the flow divider cavity serves as the main supporting component of the flow divider cavity, forming the cavity frame together with the upper and lower cover plates. The lower end of the side plate connects to the lower cover plate, forming a closed flow divider cavity structure.

[0038] Solution treatment: Solution treatment is applied to the welded flow divider cavity to eliminate internal stresses from the welding process and improve the mechanical properties and corrosion resistance of the material. Solution treatment helps improve the microstructure of the welded area and enhances its stability.

[0039] Welding (welded wire mesh): If there are additional requirements or to enhance the sealing, the wire mesh is welded to ensure the functionality of the overall structure, especially in areas requiring high strength or special protection.

[0040] Weld cleaning: Thoroughly clean the weld and welding area to remove oxides, oil, and other impurities from the welding process, ensuring that the welded parts are clean and free of contamination, thus providing a better guarantee for subsequent inspection.

[0041] Pressure resistance test: Use clean air or inert gas to conduct a pressure resistance test to ensure that the distribution chamber can withstand the predetermined pressure. During the test, the distribution chamber should maintain pressure for 10 minutes without any air leakage or seepage, ensuring the airtightness and safety of the equipment.

[0042] Full inspection: A comprehensive inspection of the flow divider cavity is conducted, including dimensions, welding quality, and sealing performance, to ensure that it meets design standards and usage requirements.
