Description

Tee bend subassembly

Technical Field

The utility model relates to a technical field of pipeline branch spare especially relates to a tee bend subassembly.

Background

As the industry develops, tees are increasingly widely used, which are typically provided at main pipe pre-branches, primarily to change the flow direction of the fluid in order to converge or separate the fluid. The three-way pipe body is widely applied to water using occasions such as kitchens or toilets.

The existing three-way pipe body is usually made of metal material. The three-way pipe body made of metal material is widely applied because of the advantages of good strength, low price, easy forming, corrosion resistance and the like.

However, when the metal tee pipe is soaked in pure water or meets water, a large amount of substances are precipitated. Taking stainless steel as an example, since the nickel content in the stainless steel reaches 8%, the precipitation amount of nickel will exceed 0.002mg/L which meets the user safety after being soaked in pure water. Taking copper as an example, since the commercial copper three-way tube body usually contains impurity elements such as nickel and lead, although lead can be oxidized and forms a protective film when meeting air, when the copper three-way tube body meets water, the protective film can fall off, so that lead is melted into water to cause lead precipitation. Therefore, the tee pipe made of metal material may seriously infringe the water safety of the user.
