Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technological scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, traditional faucet valve core mainly comprises that coordinating the flap 7 and the valve seat 8 that open and close, flap 7 upper ends to be provided with controls the valve rod 6 that flap 7 moves up and down, and valve rod 6 is connected with valve gap 9 by screw thread.After in current enter valve body chamber, can contact with flap 7, valve rod 6 and part screw thread, then flow out.Flap 7, valve rod 6 and part screw thread are metal parts, use a period of time oxidizable getting rusty afterwards, and such design easily pollutes water body.Simultaneously the pad Reusability between flap 7 and valve seat 8 is very easily damaged, and easily causes the problem such as leak.
As Figure 2-Figure 5 in order to overcome the above problems, the technological scheme of invention has been to provide a kind of water tap, comprise water-inlet cavity 1, water chamber 2 and be arranged on water-inlet cavity 1 and water chamber 2 between valve body 3, described water-inlet cavity 1 and water chamber 2 are by soft pipe connection, and described flexible pipe is provided with the valve body 3 of controlling body connected sum closure.
Described flexible pipe is fluorine flexible pipe or silica gel hose.
Described flexible pipe is teflon hose 4.
Described valve body 3 comprises valve body chamber 5, valve rod 6, flap 7, valve seat 8 and valve gap 9,5 two ends, described valve body chamber are communicated with water-inlet cavity 1 and water chamber 2 respectively, described valve gap 9 is positioned at 5 upper ends, valve body chamber, described valve rod 6 is connected with valve gap 9 by screw thread, described valve rod 6 bottoms are provided with flap 7 and valve seat 8, and described valve rod 6 drives flap 7 to move up and down with respect to valve seat 8, and described valve seat 8 coordinates flap 7 to control the connected sum closure of teflon hose 4; Described valve rod 6 upper ends are provided with rotatable handle 10.
Combine closely with water-inlet cavity 1 and water chamber 2 inwalls respectively in described teflon hose 4 two ends.
Described teflon hose 4 middle part lower surfaces and valve seat 8 are combined closely; Described valve seat 8 upper surfaces and flap 7 lower surfaces are the plane cooperatively interacting, and described flap 7 is fixedly connected with valve rod 6, and described flap 7 is rounded.
