[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] refer to Figures 1 to 5 The present embodiment is a universal concealed angle valve, which is composed of a PPR valve body 1, a valve core 2, a hand wheel 3, a pressure cap 4, an O-ring 5, a water outlet joint 6, a wear-resistant sheet 7, a decorative buckle 8, a dust cover 9 and a decorative cover 10 and other parts.

[0023] The PPR valve body 1 is formed by integrally molding a metal insert and PPR by injection molding; the water inlet end 101 of the PPR valve body 1 is made of PPR material and is used for welding PPR pipes; the water outlet end 102 of the PPR valve body is a metal insert and is used for installing a valve core 2.

[0024] The water inlet hole 201 of the valve core 2 is communicated with the water inlet port 103 of the PPR valve body 1 .

[0025] The PPR valve body 1 and the valve core 2 are installed in a threaded connection.

[0026] The handwheel teeth 301 of the handwheel 3 cooperate with the valve core teeth 202 of the valve core 2, and when the handwheel 3 rotates, the valve core 2 is driven to close.

[0027] The inner cavity of the pressure cap 4 has a threaded surface 401, which cooperates with the valve core threaded surface 203 of the valve core 2, and fixes the water outlet connector 6 to the upper end surface 302 of the hand wheel through the step surface 402 of the pressure cap 4. The pressure cap 4 is also provided with a groove 403 for placing the O-ring 5 to achieve sealing.

[0028] There is a wear-resistant sheet 7 between the lower end surface of the water outlet joint 6 and the upper end surface 302 of the hand wheel, and between the step surface 402 and the inner step surface of the water outlet joint 6 .

[0029] The water outlet connector 6 and the decorative buckle assembly 8 are threadedly matched.

[0030] The upper outer end surface of the decorative buckle 8 is provided with an arc groove 801, which cooperates with a one-yuan coin. The decorative buckle 8 can be unscrewed with a one-yuan coin, which is convenient for repairing and replacing the valve core 2.

[0031] The decorative buckle 8 can be replaced with a decorative buckle with or without a filter according to needs.

[0032] The concealed angle valve is embedded in the wall during decoration. After decoration, the dust cover 9 is removed and the decorative cover 10 is installed.

[0033] After the concealed angle valve is pre-buried and the decoration is completed, the dust cover 9 can be removed and used directly without the need to install the angle valve. The water inlet end can adjust the direction 360 degrees according to customer needs, and will not compress or bend the hose to cause damage and generate safety hazards.

[0034] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present utility model are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly. In the present utility model, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0035] The above is only a preferred implementation case of the utility model, and does not limit the utility model in any form.
