Description

Technical Field

[0002] Tee pipes are widely used in pipe networks for conveying materials. They are used at the confluence of three pipes. Their main function is to change the direction of material conveying. Commonly used tees include cast iron tees, plastic tees and stainless steel tees. Cast iron tees have higher strength but poorer corrosion resistance. Although plastic tees have strong corrosion resistance, they have lower strength. Stainless steel tees have been widely used due to their good corrosion resistance and mechanical strength. However, the stainless steel tees currently used still have defects such as poor soundproofing and weak impact resistance.

[0003] For example, a nickel-based alloy tee pipe with publication number CN205824444U includes a main pipe and a branch pipe, wherein the branch pipe is vertically connected to the middle of the main pipe, and a buffer block is provided on the inner wall of the main pipe corresponding to the lower side of the branch pipe, and both the main pipe and the branch pipe include an inner layer of a nickel-based alloy plate and an outer layer of a stainless steel substrate. A sound insulation layer is provided on the outer surface of the stainless steel substrate. The utility model strengthens the strength of the main pipe by means of a buffer block, reduces the impact force of the liquid medium on the main pipe, has a significant buffering effect, and effectively improves the service life of the entire tee pipe; in addition, a sound insulation layer is provided on the outer surface of the main pipe and the branch pipe, which can reduce the noise generated by the collision of the liquid medium when it circulates; and, the main pipe and the branch pipe use a nickel-based alloy plate as the inner layer, so they have good mechanical properties and corrosion resistance, and can save a large amount of precious metal nickel and nickel alloys, thereby reducing costs and saving materials.

[0004] The above technical solution uses nickel-based alloy materials to cast the three-way elbow, which can improve the mechanical properties and corrosion resistance of the elbow. However, the three-way elbow adopts an integrated structure, which is not convenient for clearing and maintenance when blockage occurs.

[0005] Therefore, it is necessary to invent a nickel-based alloy three-way elbow to solve the above problems. Utility Model Content
