Description

Technical Field

[0001] The utility model relates to the technical field of valve cores, in particular to an angle valve. Background Art

[0002] Angle valves are typically installed in waterways to open or close the flow of water to a water outlet. Currently used angle valves are typically made of brass alloys, which can rust over time, causing metal contamination, such as lead, in the water flowing out, potentially causing harm to the human body.

[0003] Some lead-free angle valves have appeared in the prior art, which usually provide a layer of plastic shell in a metal valve body to prevent water from flowing through the metal valve body and causing pollution. However, due to installation problems, the plastic shell usually separates the water outlet, which is subsequently installed on the metal valve body and sealed with the connecting port of the plastic shell. The sealing connection between the water outlet and the plastic shell usually adopts a conventional O-ring; it is known that the cross-section of the O-ring is circular and its sealing contact surface is small, and it needs to be subjected to greater pressure, which is prone to leakage under high water pressure conditions; at the same time, once the O-ring is damaged, even slightly, the seal may fail in a high water pressure environment.

[0007] The shell is provided with a connecting port connected to the water outlet cavity of the valve core; the water outlet nozzle is provided in the water outlet and connected to the connecting port; the outer end of the connecting port is provided with a groove that gradually expands outward along its axial direction; the water outlet nozzle has a connecting section that is adapted to the connecting port, and a sealing ring is sleeved on the connecting section, and one end of the sealing ring is provided with a sealing surface that is adapted to the inner surface of the groove.

[0008] Furthermore, the opening and the water inlet are respectively arranged at two ends of the metal valve body along a first axis, and the water outlet is arranged on a side surface of the metal valve body along a direction perpendicular to the first axis.
