Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1-3, a valve core comprises a valve sleeve 2 and a valve rod 1 made of copper.

The rotatable cup joint of valve rod 1 is in valve barrel 2, and valve rod 1 adopts the pole structure, compares in present complicated valve rod structure, and the volume production of being convenient for, and with low costs.

The valve sleeve 2 comprises a water passing sleeve 3 made of copper and a connecting sleeve 4 which is poured on the upper part of the water passing sleeve 3 and is integrated with the water passing sleeve.

The bottom end of the valve rod 1 is provided with a movable plate 11, and two circular water through holes 12 are arranged on the movable plate 11. Compare in current dysmorphism inlet opening, the processing of being convenient for, and with low costs.

The middle part of the valve rod 1 is provided with a sealing plate 13, the sealing plate 13 is rotatably connected in the water passing sleeve 4 to prevent liquid from entering the water passing sleeve 4, an annular first groove is arranged on the peripheral side wall of the sealing plate 13, and a first sealing ring 16 is embedded in the first groove.

In order to ensure that the valve rod 1 only rotates radially in the valve sleeve 2 and does not move axially, the anti-disengaging structure is designed, and comprises clamping blocks 31 arranged on two opposite sides of the top of the inner side wall of the connecting sleeve 3, an annular concave part arranged at the bottom of the inner side wall of the connecting sleeve 3, an annular clamping groove 15 arranged at the upper part of the valve rod 1 and a supporting plate 14; when the valve rod 1 is sleeved in the valve sleeve 2, the peripheral side of the top of the supporting plate 14 is abutted against the concave part, and the clamping block 31 is embedded in the clamping groove 15 to limit the axial movement of the valve rod 1 in the valve sleeve 2.
