Technical Field

The utility model relates to the technical field of fluid tee joints, in particular to a tee joint.

Background

The three-way joint is a key accessory in a pipeline system and is mainly used for realizing the diversion, combination or flow direction change of fluid, improving the flexibility of the system and facilitating the maintenance and the adjustment of flow pressure.

In the fluid mixing flow path, in order to prevent one fluid from entering the other fluid through the three-way joint, a one-way valve is arranged at one joint end of the three-way joint in the prior art, and the one-way valve is used for preventing the fluid from flowing back, but the one-way valve is independently arranged at one end of the three-way valve, so that when the flow path is cleaned, one flow path with the one-way valve is difficult to clean;

For example, if the back pressure in the mixing line is greater than the bypass line when the two fluids are mixed, this may result in a condition where one fluid or mixed fluid enters the bypass line, typically by adding a one-way valve to prevent back flow of the fluid, but in this way the bypass line is increased, which tends to increase the dead zone area when the line is sanitary.
