The cone feather edge of taper platform forms one from waterexit end to the platform 27 that meets water of feed-water end camber arch to upstream face, and described upstream face 25 is for starting the arc shaped surface of and meet water platform camber arch inner to valve head from platform edges; The wall of the described platform that meets water is positioned at the downstream of upstream face.
Described water passage hole is evenly distributed on valve head, and water passage hole, from feed-water end to waterexit end, adopts the mode tilting with valve head axis parallel or to axle center to arrange.
The water outlet of described water passage hole 23 on taper platform 26 is positioned at the vertex of a cone of taper platform.
the entrance of described water passage hole is positioned on upstream face 25.
beneficial effect:
1, the feed-water end of valve head is designed to have the arc shaped surface of level and smooth radian, has reduced the resistance of valve head to current, reduced turbulent flow, and the water outlet of water passage hole is drawn in, make water outlet more concentrated, scouring force is stronger.

Embodiment
As the throttle valve of Fig. 1, water pipe adapter, be arranged in water pipe adapter and use, water pipe adapter is mainly made up of body 1, throttle valve 2, support 3, spring 4 and screw 5 and valve seat 6.
Throttle valve comprises again valve head 21 and valve rod 22, is provided with the plural water passage hole 23 that runs through valve head on valve head, and valve rod is provided with the screw coaxial with valve rod; Valve rod is passed to spring again through the fixed hole of mid-stent, screw 5 is screwed in the screw on valve rod, spring is fixed between nut and support 3, then support is filled in body in fixing towards the direction of feed-water end from the feed-water end of body by screw cap.
Described valve seat is arranged on the downstream of throttle valve in body, and valve seat is provided with through hole, and through hole forms negative and positive towards the wall of throttle valve one end with valve head and coordinates, and valve head root is provided with the limiting platform 24 to outer process.The external diameter of limiting platform is greater than the fixed hole endoporus of mid-stent, but is less than the maximum diameter of valve head, makes to leave space between the main body of valve head and support, makes water flow to the upstream face 25 of valve head towards feed-water end by support.
Valve head is taper platform 26 towards the part of waterexit end, the vertex of a cone is towards waterexit end, the sidewall of taper platform forms negative and positive with the feed-water end wall of valve seat through-hole and coordinates, make valve head can under the promotion of water, enter through hole complete clogging through hole, when after the clogging through hole of valve head, the water inlet of water from valve head flow through, to guarantee suitable water-outlet quantity.
The cone feather edge of taper platform forms one from waterexit end to the platform 27 that meets water of feed-water end camber arch to upstream face, and described upstream face 25 is for starting the arc shaped surface of and meet water platform camber arch inner to valve head from platform edges; The wall of the described platform that meets water is positioned at the downstream of upstream face.Because upstream face and the platform that meets water form an arc shaped surface from water inlet direction to the transition of water outlet directional smoothing, can effectively release the strength of a part of water impact, be so just not easy to form turbulent flow at the feed-water end of valve head.
Described water passage hole is evenly distributed on valve head, and water passage hole, from feed-water end to waterexit end, adopts the mode tilting with valve head axis parallel or to axle center to arrange.Make to merge in the waterexit end of water passage hole the current that scouring force is stronger by the current of water passage hole.
The water outlet of described water passage hole 23 on taper platform 26 is positioned at the vertex of a cone of taper platform.
the entrance of described water passage hole is positioned on upstream face 25.
Described platform and the upstream face of meeting water forms level and smooth arc shaped surface, can reduce the resistance of valve head to current, and reduce turbulent flow.
Above-described embodiment is only for interpretation purposes of the present utility model; and be not to restriction of the present utility model, those skilled in the art, in essential scope of the present utility model; make a variety of changes or substitute, also should belong to protection category of the present utility model.
