Description

Tap valve core without water seepage and water dripping

Technical Field

The invention relates to a tap valve core, in particular to a tap valve core which is free of water seepage and water dripping and is suitable for the fields of household, commerce and public use.

Background

At present, valve cores of tap water faucets widely used in the society are light in rotation, comfortable in hand feeling and convenient to operate, but most tap water faucets begin to leak and drip water in a water closing state after being used for one, two or three years, and the longer the tap water faucet valve core is used, the more serious the tap water leaks and drips. Dissecting the valve core with leaking water, and finding that the ceramic stator plate and the ceramic rotor plate have good appearance and cannot see defects. Through long-term careful observation, after analysis and research, the main source of the water leakage problem is found to come from the fact that the ceramic valve core of the water tap is used for a long time, the ceramic stator plate and the rotor plate are attached to each other to rotate and rub through water erosion, the material thickness is subjected to wear elimination loss at the molecular level, fine thinning is generated, and water molecule leakage occurs; the water dripping can be stopped immediately if the rotating handle of the water faucet is pressed by hands, but the water dripping can be stopped immediately after the hands are loosened. The user is reluctant to replace the faucet with a new one or ask for a person to repair and replace the valve cartridge of the faucet. The common phenomenon that the service life and the efficiency of small equipment commonly used in the society are low and the loss rate is high causes huge waste when various resources including water, metal, ceramic, rubber, plastic and the like are accumulated in the whole society, and the situation needs to be changed as soon as possible and cannot be consumed any more.

Detailed Description

Fig. 1 is a reference schematic diagram of a conventional spool sleeve 1.

Fig. 2 is a reference schematic diagram of the spool sleeve 1.1 mounted with the tension spring. As shown in the figure, on the basis of the traditional spool sleeve 1, two small holes 10 are symmetrically arranged on a hexagon bolt platform.

Fig. 3 is a reference schematic diagram of the spool sleeve 1.2 with the permanent magnet ring installed. As shown in the figure, on the basis of the traditional valve core sleeve 1, an annular concave pit is arranged at the inlet 9 of the central shaft of the hexagon bolt of the valve core sleeve 1.2, and the diameter of the annular concave pit is the same as the outer diameter of the permanent magnet ring.
