Description

Technical Field

[0001] The utility model relates to a faucet, in particular to a conical water inlet faucet. Background Art

[0002] Water inlet faucets are used in the plumbing and sanitary ware industry. Water enters from the water inlet pipe and passes through the valve core cavity through the valve to control the switch of the fluid.

[0003] See also Figure 7 The conventional T-shaped faucet comprises a main pipe 1, a universal valve core 2 installed in the inner cavity of the main pipe 1, and a water inlet pipe 3 connected to the side of the main pipe 1. The water inlet pipe 3 is vertically connected to the main pipe 1. Since the water inlet pipe 3 is to be connected to a standard tap water pipe, the diameter of the water inlet pipe 3 is the same as that of the standard tap water pipe. However, the diameters of the two ends of the water inlet pipe 3 of the T-shaped faucet currently on the market are the same, so the diameter of the hole at the matching point between the main pipe 1 and the water inlet pipe 3 also needs to be the same as the diameter of the water inlet pipe 3. The aperture will occupy a part of the mounting surface 5 of the threaded assembly of the main tube 1 and the valve core 2. Since the standard universal valve core is threadedly connected with the internal thread provided on the inner wall of the upper end of the main tube 1 through the external thread provided in the middle thereof, the opening will occupy a part of the internal thread, so that a gap is formed at the position where the internal thread corresponds to the opening. After the valve core 2 is threadedly connected to the main tube 1 and the external thread of the valve core 2 corresponds to the gap of the internal thread, the external thread at the position corresponding to the gap cannot be completely matched with the main tube 1, resulting in a gap between the main tube 1 and the valve core 2, which is prone to leakage. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the purpose of the utility model is to provide a conical water inlet faucet, which can prevent leakage caused by gap between the main pipe and the valve core assembly while meeting the water flow rate and water flow velocity of the pipeline.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A conical water inlet faucet comprises a main body pipe, a valve core installed in the inner cavity of the main body pipe, and a water inlet tapered pipe connected to the main body pipe.

[0007] Furthermore, the water inlet tapered pipe comprises a straight pipe section I and a tapered pipe section I of an integrated structure, the water inlet tapered pipe is connected to the main pipe via the tapered pipe section I, and the water inlet tapered pipe pipeline is connected to the main pipe pipeline.

[0008] Furthermore, the taper of the conical pipe section I on the water inlet conical pipe is 12-16.

[0009] A conical water inlet faucet with multiple main pipes is also provided, which specifically includes a main pipe, a valve core, a water inlet tapered pipe and a tapered connecting pipe; wherein the tapered connecting pipe is connected between two main pipes, and the water inlet tapered pipe is connected to the tapered connecting pipe or the main pipe.

[0010] Furthermore, the tapered connecting pipe includes a straight pipe section II and a tapered pipe section II of an integrated structure. The tapered pipe section II is located at both ends of the straight pipe section II. The tapered connecting pipe is connected to the main pipe through the tapered pipe section II. The pipelines of the water inlet tapered pipe, the tapered connecting pipe, and the main pipe are interconnected.

[0011] Furthermore, the taper of the tapered pipe section II on the tapered connecting pipe is 12-16.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model redesigns the water inlet pipe to be a water inlet pipe with a tapered section, that is, the water inlet tapered pipe of the utility model, the water inlet tapered pipe comprises a straight pipe section I and a tapered pipe section I of an integral structure, and the narrow end of the tapered pipe section I is connected to the main pipe, the wide end is connected to one end of the straight pipe section I, the other end of the straight pipe section I is connected to the tap water pipe, the main pipe and the water inlet tapered pipe are integrally cast or connected by welding, the water inlet tapered pipe pipeline and the main pipe pipeline are connected, by designing the tapered pipe section I, the connection diameter of the water inlet pipe and the main pipe is reduced, and then the diameter of the opening of the main pipe and the water inlet pipe is reduced, so that the valve core installation surface of the main pipe will not be occupied, and the internal thread of the main pipe will not be notched, so that the external thread of the valve core and the internal thread of the main pipe can be fully matched, which solves the problem that the water inlet pipe in the prior art has a large diameter and occupies a part of the valve core installation surface, resulting in a gap between the main pipe and the valve core assembly, resulting in leakage.

[0014] 2. The utility model also designs a tapered connecting pipe, which is connected between two main pipes to form a water inlet faucet structure with multiple main pipes; the tapered connecting pipe includes a straight pipe section II and a tapered pipe section II of an integrated structure, and the tapered pipe section II is located at both ends of the straight pipe section II. By designing the tapered connecting pipe, the tapered pipe section II is connected to the main pipe, and by designing the tapered pipe section II in the tapered connecting pipe, the diameter of the tapered connecting pipe pipeline connected to the main pipe pipeline is reduced, so that the valve core installation surface will not be occupied, and while meeting the pipeline water flow and water flow rate, a gap between the main pipe and the valve core is prevented, which causes leakage.

[0025] The water inlet pipe is redesigned into a water inlet pipe with a tapered section. The water inlet tapered pipe 3 includes a straight pipe section Ⅰ30 and a tapered pipe section Ⅰ31 of an integral structure. The main pipe 1 and the water inlet tapered pipe 3 are cast as an integral whole. The water inlet tapered pipe 3 is connected to the main pipe 1. By designing the tapered pipe section Ⅰ31, the diameter of the water inlet tapered pipe 3 connected to the main pipe 1 is reduced, so that the valve core installation surface 5 will not be occupied. This solves the problem that the outer diameter of the water inlet pipe in the prior art is relatively large, occupying a part of the valve core installation surface 5, causing a gap between the main pipe 1 and the valve core 2, resulting in leakage.

[0026] Example 2: See attached Figure 3-4 This embodiment is basically the same as the embodiment 1, except that it further includes a tapered connecting pipe 4. The tapered water inlet faucet of this embodiment includes a main pipe 1, a valve core 2, a water inlet tapered pipe 3 and a tapered connecting pipe 4; the tapered connecting pipe 4 includes a straight pipe section II40 and a tapered pipe section II41 of an integrated structure, the tapered pipe section II41 is located at both ends of the straight pipe section II40, and the taper of the tapered pipe section II41 is 12-16.

[0027] This embodiment provides a water inlet faucet with double main pipes 1. The main pipe 1, the water inlet tapered pipe 3, and the tapered connecting pipe 4 are integrally cast or connected by welding. Two main pipes 1 are designed, and the tapered connecting pipe 4 is connected between the two main pipes 1. The water inlet tapered pipe 3 is connected to the tapered connecting pipe 4. The pipes of the water inlet tapered pipe 3, the tapered connecting pipe 4, and the main pipe 1 are connected. By designing the tapered connecting pipe 4, the tapered pipe section II41 is used to connect to the main pipe 1. By designing the tapered connecting pipe 4, the diameter of the pipe of the tapered connecting pipe 4 connected to the main pipe 1 is reduced, so that the valve core installation surface will not be occupied, and the gap between the main pipe 1 and the valve core 2 caused by occupying a part of the valve core surface is solved, resulting in leakage.

[0028] Example 3: See attached Figure 5-6 This embodiment is basically the same as the embodiment 1, except that it further comprises a tapered connecting pipe 4.

[0029] This embodiment provides a water inlet faucet with multiple main pipes 1. The main pipe 1 is integrally cast with the water inlet tapered pipe 3 and the tapered connecting pipe 4. Three main pipes 1 are designed. The tapered connecting pipe 4 is connected between two main pipes 1. The water inlet tapered pipe 3 is connected to the main pipe 1. The inner pipes of the water inlet tapered pipe 3, the tapered connecting pipe 4 and the main pipe 1 are connected.

In this way, the valve core installation surface will not be occupied, and the gap between the main pipe 1 and the valve core 2 caused by occupying a part of the valve core surface is solved, which leads to leakage.
