On the basis of technique scheme, described import comprises an arc-shaped edges, the two ends progressively limit formation V-type of arc-shaped edges, two V-shaped limits are arc-shaped side, the bisector of v-angle and the axes normal of cylindrical shape spool, and arc-shaped edges is corresponding with the part edge that exports overlapping, the distance between arc-shaped edges to v-angle and the equal diameters of this outlet.
On the basis of technique scheme, one end that described sealing seat contacts with cylindrical shape spool is for seal curved surface, and its external frame is the shape of a saddle caved inward, and fits tightly with cylindrical shape spool side surface; The annulus through hole of three sealing seats is taken over three respectively and is communicated with.
On the basis of technique scheme, the bottom of described cylindrical shape spool is provided with valve gap, and described valve gap is fixed on valve body by fastening piece.
On the basis of technique scheme, the top of described valve gap is provided with layer of metal pad.
On the basis of technique scheme, also comprise lower valve rod, described cylindrical shape spool is by lower valve rod and valve gap pivot joint.
On the basis of technique scheme, described drive unit is pneumatic actuator, electric actuator, hydraulic executer or manual turbine.
On the basis of technique scheme, described cylindrical shape spool, sealing seat all adopt stainless steel to make.
On the basis of technique scheme, described upper valve rod and cylindrical shape spool one-body molded.
The beneficial effects of the utility model are:
1, in the utility model, adopt cylindrical shape spool, be easy to processing compared to ball valve core, reduce cost of production, improve manufacturing efficiency.
2, in the utility model, sealing seat is shape of a saddle circle structure, and can match with cylindrical shape spool formation sealing surface, adds sealing area; In addition, when cylindrical shape spool moves up and down, sealing seat still can keep sealing state with cylindrical shape spool, improves sealing effect.
3, in the utility model, the moment of torsion of cylindrical shape spool is less, commutation, shunting, interflow and adjust flux time resistance little, avoid valve rod distortion or twist off and sealing seat fatigue problem produce, ensure that the working life of selector valve.
4, import of the present utility model is fan shaped borehole, can have precise control of flew function concurrently on the basis realizing traditional triplet commutation.The two ends progressively limit formation V-type of the arc-shaped edges of import, two V-shaped limits are arc-shaped side, and the middle separated time of v-angle is vertical with cylindrical shape valve core axis.In use, first import between v-angle is taken over one and is communicated with, when rotation angle slowly increases, the area of the import be communicated with this adapter slowly increases, by the area changed with take over the import be communicated with, namely can realize the accurate control of flow, and the regulating ratio controlled is comparatively large, flow control scope is large.
5, in the utility model, the bottom of cylindrical shape spool is provided with valve gap, this valve gap not only plays seal action, and when needing to change after cylindrical shape spool or sealing seat wearing and tearing, only need by dismounting valve gap, the quick-replaceable of cylindrical shape spool or sealing seat can be realized, not only save resource, and improve manufacturing efficiency.
