For reaching above object, the technological scheme that the utility model is taked is: a kind of three-way diverter valve with quadrant tubular spool, comprises valve body, drive unit, quadrant tubular spool and sealing seat; Be provided with valve cavity in described valve body, the both sides of valve cavity are communicated with first discharge connection and an entrance sleeve respectively, and the front of valve cavity is communicated with second discharge connection, three T-shaped distributions of adapter; The bottom of valve body is provided with mounting hole; Described quadrant tubular spool is inserted in valve cavity by mounting hole, and the end face of quadrant tubular spool and bottom surface are fan-shaped, the drift angle place of end face connects a upper valve rod, and upper valve rod also connects the drive unit driving its axial rotation through valve body; Described sealing seat is provided with two, is shape of a saddle circle structure, is separately positioned between the outer side wall of quadrant tubular spool and the first discharge connection, the second discharge connection.
On the basis of technique scheme, one end that described sealing seat contacts with quadrant tubular spool is for seal curved surface, and its external frame is the shape of a saddle caved inward, and fits tightly with quadrant tubular spool outer surface; The annulus through hole of two sealing seats is communicated with the first discharge connection, the second discharge connection respectively.
On the basis of technique scheme, described mounting hole bottom 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, the drift angle place of described quadrant tubular spool bottom surface is by the bottom surface pivot joint of lower valve rod and valve body.
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 quadrant tubular spool, sealing seat all adopt stainless steel to make.
The beneficial effects of the utility model are:
1, in the utility model, adopt quadrant tubular spool, be easy to processing compared to ball valve core, reduce cost of production.
2, in the utility model, sealing seat is shape of a saddle circle structure, and can match with quadrant tubular spool formation sealing surface, adds sealing area; In addition, when quadrant tubular spool moves up and down, sealing seat still can keep sealing state with quadrant tubular spool, improves sealing effect.
3, in the utility model, the moment of torsion of quadrant tubular spool is less, therefore avoid valve rod twist off and sealing seat fatigue problem produce.
4, in the utility model, owing to adopting quadrant tubular spool and be provided with mounting hole, after quadrant tubular spool or sealing seat wearing and tearing, can quick-replaceable, improve manufacturing efficiency.
5, in the utility model, owing to adopting quadrant tubular spool, its materials are only 1/4th of cylindrical shape spool, and only need two sealing seats to be mated work, because this reducing cost of production.
