Embodiment
See accompanying drawing, a kind of V-type three-way regulating ball valve mixed for Flow-rate adjustment and flow proportional in present embodiment, comprise valve body 1, valve gap 5, spool 2, valve rod, described spool 2 is arranged in valve body 1, described valve body 1 and valve gap 5 are combined to form two MEDIA FLOW stand in channel A, a B and medium flows out channel C, the internal orifice of each MEDIA FLOW stand in channel is respectively equipped with valve seat 3, described spool 2 is semiglobe and spool has two v-notch, spool is by valve rod driven rotary, the sealed working face of spool 2 is spheres, the corresponding valve seat of sealing working surface seals, two v-notch are arranged on the both sides of sealed working face.Therefore valve core rotation can make sealed working face move between two valve seats, sealed working face all can close a MEDIA FLOW stand in channel, also can be between two MEDIA FLOW stand in channels, realize valve core rotation can switch current direction, interflow and shunting effect.Sealed working face moves between two valve seats simultaneously, and the v-notch of sealed working face both sides controls the circulation area of two MEDIA FLOW stand in channels respectively, and two circulation area changes in percentage respectively, the flow of two MEDIA FLOW stand in channels is adjusted.
Owing to spool 2 being offered two v-notch, Spool rotating, the shape of one of them opening surface tapers to circular arc from triangle, thus changes the circulation area of valve, the continuous change of spheroid opening area realizes the Flow-rate adjustment of valve, and its Flow characteristics is approximate equal percentage characteristics.Owing to spool having two v-notch, two v-notch correspondences of spool control the area of the flow passage openings of two MEDIA FLOW stand in channels, the aperture of the fluid passage of the relative valve body of two flow passage openings (i.e. circulation area) then on spool is just different, constantly change again in rotation process, thus reach the object that the fluid in proportions entered regulates mixing.The feature that threeway and spool have two v-notch coordinates and ensures that V-type three-way regulating ball valve can not only control UNICOM between valve port or cut-out, also plays to medium the effect controlling flow simultaneously, the size of accurate flow control can carry out ratio mixing.In the present embodiment, each v-notch is symmetrical arranged up and down by horizontal plane, and two v-notch are symmetrical arranged by before and after vertical plane.
