[0002] A valve is a device used to regulate fluid flow, enabling rapid opening and closing of fluid channels. Its primary functions include fluid control, flow direction switching, overload protection, sealing, and cleaning and draining. Valves are widely used in various industrial and civilian applications to control fluid flow rate, direction, and sealing, ensuring the proper operation of systems and the safe use of equipment.

[0003] In the existing technology, the valves used in the market are made of all-metal or all-plastic materials. The advantages of the two cannot be effectively combined. The advantages and disadvantages of a single material are obvious, and it is impossible to maximize the strengths and minimize the weaknesses. The metal material has complex processing and high cost, while the all-plastic material has insufficient thread pressure-bearing strength due to the strength of the material itself, and is prone to leakage after being compressed. When making the threads, the outer shape can only be enlarged and thickened, resulting in the overall larger shape of the entire product, which is inconvenient for later construction and needs to be improved.

[0006] Preferably, a waterproof groove is provided between the valve body and the plastic coating layer.

[0007] Preferably, the number of the O-rings is two groups, and the material of the O-rings is silicone rubber.

[0008] Preferably, a sealing gasket A is provided between the movable thread copper piece and the movable joint plate, and a sealing gasket B is provided between the plastic package cover and the plastic package body.

[0009] Preferably, the valve stem is rotatably connected to the plastic coating.

[0010] Preferably, the union cap and the union plate are threadedly connected.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, plastic is used to replace part of the metal in the valve, which not only meets the functional requirements of the product, but also reduces the consumables of expensive metal, thereby effectively reducing the production cost of the product. The waterproof groove between the valve body and the plastic coating can effectively prevent water leakage between the metal and the plastic when the product is under pressure. Two sets of O-rings are set on the surface of the valve stem, which can fit tightly with the surface of the valve stem and the surrounding components to prevent the internal medium from leaking from the valve stem. The sealing gasket A and the sealing gasket B can fill the tiny gaps between the components to prevent the internal medium from leaking. The anti-slip teeth on the inner side of the threaded copper fitting can increase the bite force between the metal and the plastic to prevent loosening during installation or use.
