Problems solved by technology

[0007] 2. The magnetic force used as the driving force for opening and closing the faucet is insufficient because it is produced by the suction force between the permanent magnet and the strong magnetic material.
[0008] Due to the existence of the above deficiencies in this patent, it brings great difficulties to the implementation

Embodiment Construction

[0021] The specific structure and manufacturing process of the fully enclosed faucet according to the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] The valve body (1) and the valve stem (2) are all made of OCr18Ni9 stainless steel precision castings. Outer magnetic ring (5) adopts 1Cr13 stainless steel precision casting. The permanent magnet is made of NdFeB material.

[0023] First, the ceramic fixed piece (4) is bonded on the water outlet of the valve body (1), and the ceramic moving piece (3) is placed thereon. The four magnets in the valve stem (2) are inlaid therein with alternate polarities. The spring (6) is loaded into the valve stem (2) and placed in the valve body (1) together with the valve stem (2), and the foot of the valve stem (2) is inserted into the groove of the ceramic moving piece (3). Then the upper and lower parts of the valve body (1) are welded together to make it a fully enc...

Abstract

This invention relates to a totally enclosed water tap in water pipe. It includes totally enclosed valve body, valve stem, ceramic spool and external magnet ring. The external magnet ring and valve stem are respectively assembling the permanent magnets with the same number. The polarities of permanent magnets are alternately arranged. The external magnet ring and valve stem form one-to-one corresponded magnetic relation. This invention solves the problem in the prior patents that has little magnet force.

Description

(1) Technical field: [0001] The invention relates to a fully enclosed faucet, which is used for building water supply pipelines. (two) background technology: [0002] The faucet used in the water supply pipeline now has a structure that the valve stem passes out of the body through a through hole on the valve body, and a rubber sealing ring is used to seal between the valve stem and the valve body. Due to the aging of the rubber seal ring and the wear between the rotating valve stem, it is easy to leak water here. In this regard, in the ZL02108292.8 patent, a technical solution of a durable faucet is disclosed. The valve body is completely closed to the outside world except for the water inlet and outlet, and the water will never leak out. Ceramic fixed pieces are installed in the valve body from bottom to top, and the ceramic moving piece floats on the ceramic fixed piece to form a flat seal. The ceramic moving piece is equipped with a valve stem made of strong magnetic m...
