[0028] In some embodiments, the valve body 1 includes a large-diameter section and a small-diameter section, the large-diameter section being disposed near a first end of the valve body 1 and the small-diameter section being disposed near a second end of the valve body 1; the inner cavity of the valve body 1 includes a first cavity 100 and a second cavity 110 that are in communication with each other, the first cavity 100 being formed in the small-diameter section and the second cavity 110 being formed in the large-diameter section;
[0029] This swing valve also includes a first valve stem limiting sleeve 5 and a second valve stem limiting sleeve 6. The first valve stem limiting sleeve 5 is disposed in the first cavity 100, and a first limiting hole 51 is formed on the first valve stem limiting sleeve 5. The second valve stem limiting sleeve 6 is disposed at the connection between the first cavity 100 and the second cavity 110. The second valve stem limiting sleeve 6 is provided with a second limiting hole 61 corresponding to the first limiting hole 51. The first end of the valve stem 2 passes through the first limiting hole 51 and the second limiting hole 61 in sequence and is connected to the valve core 3.
[0030] In some embodiments, a spherical hinge portion 21 is provided on the stem segment of the valve stem 2 located in the first cavity 100, and a hinge shaft 22 is provided on the spherical hinge portion 21. The hinge shaft 22 extends radially along the valve body 1. A hinge hole corresponding to the hinge shaft 22 is provided on the inner wall of the first cavity 100. Both ends of the hinge shaft 22 are located in the hinge hole so that the valve stem 2 can rotate around the hinge shaft 22. The structure of the first limiting hole 51 is the same as the structure of the second limiting hole 61. The length direction of the first limiting hole 51 is greater than the width direction of the first limiting hole, and the length direction of the first limiting hole is perpendicular to the axial direction of the hinge shaft.
[0031] In some embodiments, the first valve stem limiting sleeve 5 includes a cylindrical body, the interior of which forms a first cavity 100, and a rotating groove adapted to the spherical hinge portion 21 is provided in the first cavity 100, the spherical hinge portion 21 being rotatably disposed in the rotating groove; the cylindrical body is open at one end facing the valve core 3, and closed at the other end facing away from the valve core 3; a first limiting hole 51 is formed on the end face of the cylindrical body facing away from the valve core 3.
[0032] In some embodiments, the second valve stem limiting sleeve 6 includes a frustum-shaped body, and a second limiting hole 61 is formed on the frustum-shaped body; a connecting part is provided on the cylindrical body, and a mating part matching the connecting part is provided on the frustum-shaped body; the connecting part and the mating part are engaged to fix the first valve stem limiting sleeve 5 and the second valve stem limiting sleeve 6 together.
[0033] In some embodiments, the connecting portion is a plurality of engaging protrusions 52 spaced apart on the periphery of the end of the cylindrical body facing the valve core 3, and the mating portion is an annular engaging groove 62 provided on the periphery of the end of the frustum-shaped body facing the cylindrical body.
[0034] In some embodiments, the valve core 3 includes an elliptical frustum-shaped body, with sealing surfaces 31 provided on both sides of the elliptical frustum-shaped body in the direction of its minor axis; the frustum-shaped body has a sealing portion 63 at one end facing the valve core 3, which fits against the corresponding sealing surface 31. The valve core 3 is pressed against the valve cover seat 7 and can swing with the valve stem 2 in the inner cavity of the valve body 2. The relative position of the valve core 3 and the valve cover seat 7 is fixed by friction. The valve stem 2 is driven by the handle to swing, thereby switching the position of the valve core 3, so that the valve core 3 moves between the closed position and the open position.
[0035] In some embodiments, the swing valve further includes a valve cover seat 7, which is disposed at the second end of the valve body 1. A valve inlet 12 is formed on the valve cover seat 7 and the valve inlet 12 is located on the swing path of the valve stem 2. There are two valve outlets 11, which are disposed on the wall surface of the valve body 1 near its first end.

[0037] In some embodiments, the valve stem 2, the first valve stem limiting sleeve 5, the second valve stem limiting sleeve 6, the valve core 3, and the valve cover seat 7 are all made of plastic, while the remaining components are made of metal. Using plastic for the valve stem 2, the first valve stem limiting sleeve 5, the second valve stem limiting sleeve 6, the valve core 3, and the valve cover seat 7 improves the overall corrosion resistance of the valve. Plastic itself does not absorb water and maintains stable performance even under long-term contact with water. Compared to metal, plastic faucets do not experience electrochemical corrosion due to dissolved oxygen and other electrolytes in the water, significantly extending their service life. The use of metal for the other components of the swing valve ensures the installation strength of the valve.
[0038] The swing valve provided in this embodiment has the following beneficial effects: when the user's hands are occupied and it is inconvenient to rotate the handle, but the user can still use their arms or other parts of the body to assist in the operation, the water flow can be controlled simply by pushing the handle 4 of the swing valve with the elbow.
[0039] The second aspect of this utility model provides a faucet, including a hexagonal cap 8 and a swing valve as described in the first aspect of this utility model. The hexagonal cap 8 is sleeved on the valve body and is used to fix the swing valve to an external pipe.
[0040] In some embodiments, sealing elements 13 are provided between the first valve stem limiting sleeve 5 and the inner wall of the valve body 1, between the outer wall of the valve body 1 and the hexagonal cap 8, and between the hexagonal cap 8 and the external pipe. This faucet has a good sealing effect and is easy to use, with a faster opening and closing speed compared to traditional rotary faucets.
[0041] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
