Description

Technical Field

[0001] The utility model relates to the technical field of pipe connectors, in particular to a U-shaped branch pipe fitting. Background Art

[0002] At present, the piping system of water heating, floor heating and air conditioning is relatively complicated. Many branches need to be divided from the two main water outlet and return water lines to install automatic exhaust valves, pressure differential bypass valves, pressure gauges, safety valves, water supply ball valves, water outlet ball valves and other components. Every time an additional instrument component is installed, the main line needs to be cut off, and a three-way pipe fitting is added to the main line. The added third port is used to install the required instrument component, which makes the on-site installation of the pipeline more cumbersome, and the more installation points, the more water leakage points there are.

[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the first pipe interface and the second pipe interface face the rear side, and the branch interfaces are divided into two groups, one group of interfaces faces upward, and the other group of interfaces faces forward.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the branch interface is an internal thread interface or an external thread interface, and the branch interfaces are perpendicular to the main body segment.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: a valve core and a valve stem for driving the valve core to rotate are arranged in the ball valve, and a handle is arranged on the top of the valve stem.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the bending angles of the first bending section and the second bending section are both 90 degrees.

If there is a branch interface without a ball valve, it is preferred to use this branch interface. The branch interface with a ball valve can be used as a spare interface. In daily use, close the ball valves on these spare branch interfaces without affecting the use of the overall pipe connector.

[0011] Compared with the prior art, the beneficial effects of the utility model are: various three-way pipe connectors are brought together to reduce the difficulty of on-site installation of the tee and improve installation efficiency; multiple branch interfaces are set, and a shut-off ball valve is provided on all or part of the branch interfaces, and the branch interface with the ball valve can be used as a spare interface, thereby improving the versatility of the overall pipe fittings, being suitable for the installation of pipelines with different branch numbers, and reducing the cost of pipe fitting manufacturing molds.
