Abstract
The utility model discloses a tap that is wear resistant and is capable of self-repairing. The tap comprises a valve housing, a valve core, a valve seat and a valve rod. The valve core and the valve seat are made from wear-resistant rubber. The valve core is a protruding sphere. The inner hole of the valve seat is a recessed sphere. The protruding sphere of the valve core matches the recessed sphere of the valve seat. The tap has a finely flexible rubber sealing surface, allows operation pressure to be increased to press a groove for self-restoration once the groove is generated, is not liable to leak water, and has the long service life.
Description
Technical field
The utility model relates to a kind of household tap water tap, and a kind of water tap of wear-resisting ability self repair is especially arranged.
Background technique
At present existing water tap mainly is made up of valve casing, spool, valve seat, operating stem, and wherein spool and valve seat adopt metal or plastic production, and this material is harder; Do not have flexibility, easy to wear, sealing surface is prone to produce groove and leaks; Poor because of material softness property, be difficult to self repair, working life is just short.
Summary of the invention
Have short deficiency of self repair difference life-span easy to wear in order to overcome existing water tap, the purpose of the utility model provides a kind of a kind of water tap that the self repair of wear-resisting ability is arranged.
The utility model technological division that is adopted of dealing with problems is: it comprises valve casing, spool, valve seat, valve rod; Wherein spool and valve seat adopt abrasive rubber to process; Spool is protruding spheroid, and the valve seat endoporus is the concave ball shape body, and the convex-concave spheroid of spool and valve seat matches.Abrasive rubber is not easy to wear, also has ductility, and especially ball shape has better ductility, and all sealing surfaces produce has groove to leak, and increases operating stem pressure, and rubber seal face is squeezed and can flattens groove, keeps sealing, and leaking can self repair.Thereby reach the purpose that the utility model has the self repair of wear-resisting ability.
The beneficial effect of the utility model is, have wear-resisting can self repair, antileaking, the life-span is long.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Figure is the utility model embodiment's a drawing in side sectional elevation.
Among the figure 1, valve rod 2, spool 3, valve seat 4, valve casing
Embodiment
In the embodiment shown in the figure, the centre is provided with valve seat 3 in valve casing 4, and valve seat 3 usefulness abrasive rubbers are processed, and valve seat 3 endoporus are the concave ball shape body.Spool 2 usefulness abrasive rubbers are processed protruding spheroid, and spool 2 centers and valve rod 1 link together and pack in the valve casing 4, the concave ball shape endoporus of valve seat 3 and the protruding spheroid of the spool 2 composition sealing surface that matches.The ball shape of this rubber ball-shaped sealing surface has fine ductility, and self-healing properties is strong, antileaking, long service life.
Claims (1)
