The utility model is to adopt following technological scheme to realize above-mentioned purpose: a kind of faucet valve core base, it is characterized in that, it comprises a plastic feet that is installed on the spool bottom and is interconnected with spool water intake, water outlet, and the outer periphery of this base is equipped with and the close-connected seal ring of tap main body.
As further specifying of such scheme, described base is a monolithic construction, comprises the following connection end face that go up to connect end face, is connected with tap main body that is connected with spool, and as the side of sealing surface, also is provided with the water outlet notch on the side.
Described base is a cylindrical structure, and its upper bottom surface is last connection end face, and bottom surface is for connecting end face down, and the side is the cylndrical surface.
The described end face that go up to connect is provided with and spool water intake, the corresponding water inlet that communicates of water outlet, osculum, and the positioning hole that is connected with the spool bottom, and this positioning hole is a blind hole.
Described water outlet notch upwards communicates with osculum at datum axle.
The described end face that connects down is provided with water inlet and angle, this water inlet be arranged on that the water inlet that is connected end face is coaxial to communicate, this angle and tap main body are connected.
Described water inlet comprises cold water inlet hole and hot water inlet hole.
Hexagon nut is equipped with in described water inlet, and the tapped hole in this hexagon nut is stepped.
It is three stepped that the tapped hole of described hexagon nut is, and minor diameter of thread is successively decreased to the upper end successively by the lower end.
Described hexagon nut is connected with intake pipe.
Described intake pipe comprises cold water inlet road and hot water inlet pipe road.
Described seal ring is contained on the base side along the base axial distribution.
Described seal ring external diameter is greater than last connection end face, connect the external diameter of end face down.
The beneficial effect that the utility model adopts above technological scheme to reach is:
1. the utility model adopts the integrated type spool base of plastic material, and not only shaping is easy, technological process is simple, and can adopt the punching block injection molded, and the recycling mould greatly reduces equipment cost.
2. base material of the present utility model is plastics, compares metal material, and not only cost of material reduces greatly, weight saving, and also easy than metal for the recycling of scrap, waste product, more can contaminated air.
3. the utility model adopts integrated type spool base, and component are few, reduced packing problem, installation, dismounting, easy to maintenance quick.
4. the utility model material is plastics, makes finished product that certain elasticity be arranged, and adaptivity is good, and is provided with multi-layer sealed circle, so sealability is better, stops seepy question.
5. after adopting plastic feet described in the utility model, tap main body simple in structure many, its mould, core manufacturing are also oversimplified thereupon, help the ball blast sand removal of foundry goods, and foundry goods is easy to cast, weight saving, has improved machining efficient, polishing efficiency and plating rate of good product.
