Furthermore, an inner neck is arranged in the first pipe orifice, the gear bars are arranged in parallel along the communication direction of the first pipe orifice and the second pipe orifice, and one end of each gear bar in the length direction is connected with the inner neck.

Further, the gear bar includes a detent aligned in a linear direction with the third nozzle.

Furthermore, the valve core seat is provided with a plurality of through holes matched with the valve core.

The utility model provides a pair of tap's three-way valve structure inlays through the case seat with the cake form and establishes in the tee bend is intraductal, in the tee bend intraductal a large amount of spaces of having reserved to the equipment is convenient.

Compared with the prior art, the utility model discloses following beneficial effect has:

first, space is saved in the tee pipe, and other spare and accessory parts can be configured. The hose in a water tap such as a spring extension tap can pass through the space in the tee pipe and be connected into the water outlet pipe from the lower part of the valve core seat, so that the hose can be extended in the tee pipe.

And secondly, the assembly steps are more convenient. Traditional column copper core seat still need install the ring welding between in order with the inside cooperation of pipe fitting additional, and the copper core seat of this structure only need the joint in fender position strip department.

And thirdly, the water inlet pipe and the water outlet pipe are directly welded in the valve core seat, the whole body is inserted into the position of the gear strip, the sealing treatment of the water inlet pipe and the water outlet pipe is completed outside the three-way pipe, and the water inlet pipe and the water outlet pipe of the traditional columnar copper core seat need to be added with a raw material belt or a sealing ring at the joint for sealing treatment.
