The cone feather edge of tapered land to upstream face formed one from waterexit end the platform 27 that meets water to feed-water end camber arch, described upstream face 25 is the arc shaped surface to valve head interior and the platform camber arch that meets water 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 and arranges with valve head axis parallel or the mode that tilts to axle center.
The described water outlet of water passage hole 23 on tapered land 26 is positioned at the vertex of a cone of tapered land.
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 the arc shaped surface with level and smooth radian, reduces the resistance of valve head to current, decrease turbulent flow, and drawn in by the water outlet of water passage hole, make water outlet more concentrated, scouring force is stronger.

Embodiment
As Fig. 1, a kind of throttle valve, be arranged in water pipe adapter and use, water pipe adapter forms primarily 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, and valve head is provided with the plural water passage hole 23 running through valve head, and valve rod is provided with the screw coaxial with valve rod; Screw 5, again through spring, is screwed in the screw on valve rod, is fixed on by spring between nut and support 3, then support is filled in body internal fixtion towards the direction of feed-water end from the feed-water end of body by screw cap by fixed hole valve rod being passed mid-stent.
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 limiting platform 24 outwardly.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, enables water flow to the upstream face 25 of valve head towards feed-water end by support.
Valve head is tapered land 26 towards the part of waterexit end, the vertex of a cone is towards waterexit end, the sidewall of tapered land forms negative and positive with the feed-water end wall of valve seat through-hole and coordinates, valve head is enable to enter through hole under the promotion of water and complete clogging through hole, when after the clogging through hole of valve head, water flows through from the water inlet valve head, to ensure suitable water-outlet quantity.
The cone feather edge of tapered land to upstream face formed one from waterexit end the platform 27 that meets water to feed-water end camber arch, described upstream face 25 is the arc shaped surface to valve head interior and the platform camber arch that meets water from platform edges; The wall of the described platform that meets water is positioned at the downstream of upstream face.Effectively can release the strength of a part of water impact because upstream face and the platform that meets water form one from water inlet direction to the arc shaped surface of water outlet directional smoothing transition, so just be 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 and arranges with valve head axis parallel or the mode that tilts to axle center.Make to merge into the stronger current of scouring force by the current of water passage hole in the waterexit end of water passage hole.
The described water outlet of water passage hole 23 on tapered land 26 is positioned at the vertex of a cone of tapered land.
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 used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
