Abstract
The utility model disclose a valve core of a water faucet, comprising an engineering plastics shell and a valve lever, wherein, a coaxial seal cover of the upper part of the shell is arranged on the valve lever and a start-stop ceramic chip, a water inlet ceramic chip are arranged in the inner of the lower part of the shell in turn. A water outlet which is corresponded to the exit of the start-stop ceramic chip is arranged on the shell. The start-stop ceramic chip is connected with the valve lever. The water inlet ceramic chip is fixedly connected with the shell. A ring seal plate is arranged at the lower end of the shell. The utility model is characterized in that: a retaining ring is arranged between the seal plate and the water inlet ceramic chip and an O-shaped circle is arranged between the retaining ring and the water inlet ceramic chip. The utility model has the advantages of low cost and good sealability. Due to the arrangement of the retaining ring with the O-shaped circle between the seal plate and the water inlet ceramic chip, when the water temperature is increased and the shell is softened, the water does not leak from the shell through the close contact of the O-shaped circle and the end face of the water inlet ceramic, therefore, the sealability of the valve core is ensured.
Description
Technical field
The utility model relates to a kind of water tap, especially relates to a kind of spool of water tap.
Background technique
The housing of the spool of a lot of in the market water taps all adopts the copper product manufacturing, is provided with sealing gasket in the lower end of housing, leaks when water tap is closed preventing; Because the cost of copper is higher, there are the human engineering plastics to come instead of copper to do the housing of spool, to reduce cost, but engineering plastics ratio when water temperature is higher is easier to deliquescing, cooperating between sealing gasket and the plastic casing is not tight, because the effect of hydraulic pressure, the water capacity easily spills between sealing gasket and plastic casing, thereby causes water tap to leak when closing; In addition, no matter be the housing of what made, because the aperture efficiency that forms between the outlet port of housing and the keying ceramics is bigger, water tap goes out water noise when opening bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of low cost and can guarantee to satisfy the spool of the water tap of seal request.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of spool of water tap, comprise engineering plastics housing and valve rod, the top co-axial seal of described housing is set on the described valve rod, be disposed with from top to bottom in the described lower part of frame and open and close ceramics and water inlet ceramics, described housing is provided with and the corresponding water outlet of the outlet of described keying ceramics, described keying ceramics is connected with described valve rod, described water inlet ceramics is fixedlyed connected with described housing, the lower end of described housing is provided with the sealing gasket of annular, be provided with retaining ring between described sealing gasket and the described water inlet ceramics, be provided with O type circle between described retaining ring and the described water inlet ceramics.
Described retaining ring is provided with circular groove, and described O type circle is arranged in the described circular groove.
Be provided with branch water comb between described keying ceramics and the described valve rod, be wholely set a plurality of minutes water teeth of symmetry on the end face of described minute water comb, the water comb was connected on the described keying ceramics in described minute, the water tooth was corresponding mutually with the outlet of described keying ceramics in described minute, and described valve rod and described minute water comb interconnect.
Be provided with the feel spacer between described valve rod and the described housing.
The both sides of described water inlet ceramics have been wholely set locating bump, and described housing is provided with locating slot, and described locating bump and described locating slot cooperatively interact.
Compared with prior art, the utility model has the advantages that lower, the good airproof performance of cost, owing between sealing gasket and water inlet ceramics, be provided with the retaining ring of band O type circle, guaranteed in the higher housing deliquescing of water temperature, by O type circle with the water inlet ceramics end face between tight the contact, make water can from housing, not spill, thereby guaranteed the sealing of spool; And on the keying ceramics, be connected with branch water comb, and make water branch water tooth shunting by dividing water to comb when flowing out water outlet, reduced the noise of current effectively; In addition, between valve rod and housing, be provided with the feel spacer, reduced the friction between valve rod and the housing, also make the rotation of valve rod more flexible simultaneously.
