The cylinder body is welded by three parts: the upper part of the cylinder body, the middle part of the cylinder body, and the lower part of the cylinder body. The upper part of the cylinder body includes a flat plate body and a valve core installation ring arranged at the lower part of the front end of the flat plate body. The inner side of the valve core installation ring is provided with a first internal thread; the middle part of the cylinder body includes a valve core housing and a water outlet cavity main body integrally connected and made. The water outlet cavity main body is a groove body surrounded by a side wall and a bottom wall, and a water outlet is arranged at the lower part of the front end of the water outlet cavity main body; the lower part of the cylinder body is an inlet seat processed and made of a solid metal material. Two water inlet channels are axially and parallelly processed from top to bottom on the inlet seat. The lower part of the inlet seat is provided with a second internal thread and an external thread; the flat plate body is welded to the upper parts of the valve core housing and the water outlet cavity main body, and the weld seam is polished. The upper part of the inlet seat is welded to the lower part of the valve core housing, and the weld seam is polished.

[0005] Further, the valve core installation ring and the flat plate body are integrally stamped and made.

[0006] Further, the upper part of the inlet seat is provided with a welding step, and the lower part of the valve core housing is adapted to and welded to the welding step.

[0007] Further, the flat plate body and the valve core installation ring are integrally hot processed by a mold.

[0008] Further, the cross-sectional shape of the cylinder body includes a circle and a square.

[0009] In order to improve the stability of the overall use of the faucet, the metal solid materials used for the water inlet seat include carbon steel materials and alloy steel materials to increase its weight.

[0010] The beneficial technical effects of the present utility model: The cylinder body is welded by three parts, namely the upper part of the cylinder body, the middle part of the cylinder body and the lower part of the cylinder body. The structure is simple, the connection is convenient, and the manufacturing is easy. There is no need to install a water outlet pipe in the water outlet cavity, and it can be directly used to hold water and drain water, improving the drainage capacity; there is no need to add a partition in the internal structure of the cylinder body, but directly connect to the two water inlet channels provided on the water inlet seat, simplifying the connection structure. The structure of the valve core does not need to be complex, reducing the number of parts and the need for complex mold opening, thus reducing the manufacturing cost. The water inlet seat is made of steel solid material, increasing the weight and improving the stability of the overall use of the faucet. BRIEF DESCRIPTION OF THE DRAWINGS
