[0027] Reference Figures 1 to 4A three-way valve includes: a valve body 1, a pipe body 2 is provided on the valve body 1, a pipe cover 3 is threadedly installed at the pipe mouth of the pipe body 2, the pipe cover 3 is connected to the pipe body 2 through a connector 4, the connector 4 is made of a flexible material, the connector 4 includes a first connecting ring 41, the first connecting ring 41 is rotatably sleeved on the pipe body 2, a connecting belt 42 is fixedly installed on the first connecting ring 41, a second connecting ring 43 is fixedly installed on one end of the connecting belt 42, a connecting column 32 is fixedly installed on the top of the pipe cover 3, and the second connecting ring 43 is rotatably sleeved on the connecting column 32. The pipe body 2 is blocked by the pipe cover 3, and after the pipe cover 3 is removed, the pipe body 2 can be used normally, and the pipe cover 3 can be hung on the pipe body 2 through the connector 4 to prevent it from being lost.

[0028] As a preferred embodiment, the connecting member 4 is made of rubber.

[0029] As a preferred embodiment, a sealing gasket 31 is provided at the bottom of the tube cover 3. When the tube cover 3 is threadedly mounted on the tube body 2, the sealing gasket 31 is in sealing contact with the top of the tube body 2, thereby ensuring that the tube cover 3 and the tube body 2 are sealed.

[0030] As a preferred embodiment, a water stop valve 5 is provided on the pipe body 2. When the pipe cover 3 needs to be removed, the water stop valve 5 is closed first to prevent water from overflowing when the pipe cover 3 is removed.

[0031] As a preferred embodiment, in order to ensure that the water stop valve 5 is in a closed state when the pipe cover 3 is removed, the present application also includes a limit rod 6, and a limit block 33 is provided on the pipe cover 3. When the water stop valve 5 is closed, the limit rod 6 and the limit block 33 are staggered. When the water stop valve 5 is opened, the limit rod 6 and the limit block 33 correspond. By cooperating with the limit rod 6 and the limit block 33, the rotation of the pipe cover 3 can be restricted when the water stop valve 5 is not closed.

[0032] As a preferred embodiment, the limit rod 6 is fixedly installed on the valve stem of the water stop valve 5, and the limit rod 6 can rotate with the valve stem, and when the water stop valve 5 is opened, the limit rod 6 is in a vertical state and corresponds to the limit block 33. At this time, when the pipe cover 3 is rotated, the limit rod 6 will block the limit block 33, thereby limiting the rotation of the pipe cover 3 and preventing water from overflowing; however, this embodiment has certain disadvantages. If the pipe cover 3 is rotated vigorously, the valve stem will be pushed to rotate in the opposite direction, and thus the pipe cover 3 cannot be effectively limited when the water stop valve 5 is opened.

[0033] As a preferred embodiment, a mounting seat 21 is fixedly installed on the tube body 2, and a limit rod 6 is slidably installed on the mounting seat 21. A protrusion 51 is provided on the valve stem of the water stop valve 5. When the water stop valve 5 is opened, the protrusion 51 rotates upward and pushes the limit rod 6 to move upward, so that the limit rod 6 corresponds to the limit block 33, thereby limiting the rotation of the pipe cover 3. Conversely, when the water stop valve 5 is closed, under the action of gravity, the limit rod 6 moves downward and is offset from the limit block 33.

[0034] As a preferred embodiment, a spring 7 is provided on the sliding sleeve of the limit rod 6, and the two ends of the spring 7 are respectively fixedly connected to the mounting seat 21 and the limit rod 6, which is conducive to the limit rod 6 moving downward and retracting.
