Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a straight-through concealed angle valve. Background Technology

[0002] Angle valves are mainly used in conjunction with washbasins or kitchen faucets, and are usually installed in small spaces such as bathroom cabinets / cabinets. Conventional angle valve installation involves pre-burying the internal bend and then installing the angle valve on the internal bend, which is a relatively complicated operation. At the same time, the existing angle valves and internal bends are mostly connected by PTFE tape, which poses a risk of leakage after prolonged use. Utility Model Content

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A straight-through concealed angle valve includes a valve body, a valve core, a handwheel, a wear-resistant pad, a sealing gasket, a water outlet connector, a pressure cap, and an O-ring. The valve core is fixed on the valve body, and the water inlet hole on the valve core is connected to the water outlet hole on the valve body. The handwheel is sleeved on the valve core, and the handwheel and the valve core are connected by a toothed engagement. A water outlet connector is provided at the upper end of the valve core. The pressure cap is fixedly connected to the upper end of the valve core, and the pressure cap fixes the water outlet connector between the pressure cap and the valve core. A sealing gasket is provided between the pressure cap and the valve core. A wear-resistant pad is provided between the water outlet connector and the handwheel. An O-ring is provided between the pressure cap and the water outlet connector.

[0005] The valve body is integrally injection molded from a PPR component and a metal insert. The PPR component of the valve body has a water inlet end for welding a PPR pipe fitting. After welding, the pipe fitting and valve body form a single integrated structure, eliminating the need for Teflon tape wrapping and reducing the risk of future leaks. The metal insert of the valve body has a water outlet end for installing the valve core. The tail of the metal insert has several dovetail grooves, which are embedded within the PPR component.

[0006] The metal insert is provided with a mounting base, and the valve core is fixedly connected to the mounting base.

[0007] The metal insert is covered with a decorative cap.

[0008] The centerlines of the pressure cap, water outlet connector, sealing gasket, and valve core are on the same vertical line.

[0009] The handwheel is provided with handwheel teeth, and the valve core is provided with valve core teeth. The handwheel teeth and valve core teeth are connected in a cooperative manner, and the handwheel rotation drives the valve core to close.

[0010] The inner cavity of the pressure cap is a threaded hole surface, which is threadedly connected to the threaded shaft surface on the valve core. The bottom surface of the pressure cap presses against the inner stepped surface of the water outlet connector, fixing the water outlet connector between the pressure cap and the valve core.

[0011] The outer surface of the pressure cap has a groove, and an O-ring is placed in the groove. The top of the pressure cap is provided with an internal hex wrench position.

[0012] The water outlet connector is equipped with a wrench position.

[0013] The water outlet connector is connected to an adapter via a thread, and the adapter is connected to a flexible hose, which is parallel to the wall.

[0014] Compared with the prior art, this utility model has the following advantages: The concealed angle valve of this utility model requires no secondary installation after pre-embedding; the connection between the concealed angle valve and the pipeline is achieved through hot-melt welding, resulting in a single integrated structure between the pipe fitting and the valve body after welding, eliminating the need for Teflon tape wrapping and reducing the risk of future leakage. This utility model also features a detachable design, allowing for easy replacement of the valve core by removing the pressure cap, facilitating maintenance. Attached Figure Description
