Water tap
Technical field
The present invention relates to a kind of water tap, especially the improvement of the valve seat of water tap and valve core structure.
Background technique
The water tap of Xiao Shouing comprises leading main casing in the market, the tap main casing comprises valve seat, cold intake pipe, hot intake pipe and outlet pipe, valve seat is provided with cavity, be mounted with mangetic core assembly in the cavity, also be provided with regulating handle on the tap main casing, mangetic core assembly comprises fixed valve plate, moving valve plate, guide holder, retainer and rocking bar, fixed valve plate, moving valve plate, guide holder, retainer and rocking bar all are arranged at lower cover and loam cake surrounds in the cavity that forms, fixed valve plate is positioned at down and covers, under cover and offer the flowing water passage, water inlet and osculum on the flowing water channel alignment valve seat, also be provided with packing ring on the flowing water passage of lower cover, the loam cake and the lower cover that comprise mangetic core assembly are arranged in the valve seat cavity, and are pressed in the cavity with gland, the upper end of loam cake offers through hole, and rocking bar stretches out and is connected with regulating handle from the through hole of loam cake.The structure of the mangetic core assembly part of this water tap is too complicated, fixed valve plate wherein, moving valve plate, guide holder, retainer and rocking bar must at first be arranged in the cavity that loam cake and lower cover be combined into just can be placed into the valve seat cavity, and the water inlet of valve seat bottom and osculum need through lower cover could with the flowing water through hole UNICOM of fixed valve plate, in order to make the water seepage easily not by lower cover, also packing ring must be set on the flowing water passage of lower cover, the packing ring of this sealing usefulness wears out easily, leaks.
Summary of the invention
Technical problem to be solved by this invention provides a kind of water tap, and the parts that the mangetic core assembly of this water tap partly relates to lack than existing water tap, makes easylier, and cost is relatively low, and antileaking.
For this reason, water tap provided by the invention comprises leading main casing, the tap main casing comprises valve seat, intake pipe and outlet pipe, valve seat is provided with cavity, be mounted with mangetic core assembly in the cavity, also be provided with regulating handle on the leading main casing, described mangetic core assembly comprises fixed valve plate, moving valve plate, guide holder, retainer and rocking bar, fixed valve plate directly is fixed on the bottom of valve seat upper plenum, and the flowing water through hole on the fixed valve plate is aimed at water inlet and the osculum on the valve seat respectively.
Because the fixed valve plate of water tap of the present invention directly is fixed on the valve seat, therefore need not to be provided with lower cover with the location fixed valve plate, also not be used on the flowing water passage of lower cover packing ring is set, therefore making the related parts of mangetic core assembly reduces many, so just make the structure of water tap of the present invention simpler, make easylier, manufacturing efficiency is higher, can also reduce material and cost of labor, also can not exist simultaneously owing to the aging tap that causes of packing ring leaks.
