Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to angle valve products. Background Art

[0002] In order to meet product standard requirements, angle valves in the bathroom sector are usually made of metal, with copper, iron, and steel being the most common materials. Pure copper is of good quality and causes minimal water pollution, making it a relatively good production material. However, copper has a high material cost, which directly leads to a higher selling price. Other metal materials will release substances from the metal during use (such as lead, which is harmful to the body), which directly causes water pollution. This is detrimental to the safety of people's drinking water. Currently, some industry technicians have made structural improvements to angle valves to address the above issues, but some structures still cannot effectively solve the problem of water pollution caused by water flowing through the metal body of the angle valve. Some structures are difficult to produce and manufacture, which will increase production costs or even make them impossible to implement. Utility Model Content

[0003] The purpose of the utility model is to provide an angle valve which can completely avoid the contact between water flow and metal of the angle valve and has a structure that is easy to produce, manufacture and assemble, and does not pollute the water flow with metal.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: an angle valve for metal-free water flow, comprising an angle valve body having a connected water inlet, water outlet and main body cavity, and a valve core installed in the main body cavity, the valve core being provided with a water inlet and a water outlet, and also comprising a docking pipe fitting nested in the water inlet and / or water outlet, the docking pipe fitting being installed and connected to the water inlet and / or water outlet through a locking structure, the inner end of the docking pipe fitting being docked and connected to the water inlet and / or water outlet of the valve core in the main body cavity through a docking sealing structure, and the water outlet of the valve core being arranged in one or more ways.

[0005] The water inlet and / or water outlet of the valve core is provided with a positioning docking section or a positioning docking seat, and the inner end of the docking pipe is nested and connected with the positioning docking section or positioned docked with the positioning docking seat through the docking sealing structure.

[0006] A positioning and orientation structure for positioning and orientation installation of the valve core is provided between the valve core and the angle valve body.

[0007] The outer end of the butt joint pipe is provided with a sealing separation structure which can separate the water inlet and / or the water outlet from the water flow.

[0008] The outer end of the butt joint pipe extends vertically outward to form an outer end edge that blocks the end surface of the water inlet and / or the water outlet.

[0009] The docking pipe fitting is provided with an installation auxiliary structure for installation and connection operations.

[0010] The installation auxiliary structure is arranged such that the inner side wall of the outer end port of the docking pipe fitting has a structure that can be directionally matched with an assembly tool.

[0011] By adopting the above technical solution, the beneficial effects of the present utility model are as follows: The angle valve with the above structure is provided with a docking pipe fitting nested in the water inlet and / or outlet pipe orifice. The docking pipe fitting can be directly docked with the water inlet and / or outlet of the valve core. During the use of the angle valve, the water flow can be completely isolated from the angle valve body. Without contact, substances that may affect human health on the angle valve body will not precipitate. Thus, the docking pipe fitting can be made of materials such as plastics that meet the requirements for safe drinking water for human health. The requirements for the material of the angle valve body can be reduced. Therefore, it can not only achieve the purpose of no metal pollution of the water flow but also reduce the production cost of the angle valve product. In addition, in the above structure, the docking pipe fitting is directly docked with the water inlet and / or outlet of the valve core, rather than through another structure arranged in the main body cavity of the angle valve body for docking. This can simplify the product structure, reduce the production difficulty and the production and assembly processes, and thus better achieve the above-mentioned purpose and effect of the present utility model.
