The utility model discloses a vertical pulling formula electric two way valve, the mountable is on the air conditioning equipment of heating ventilation air conditioning system end, its structure includes the valve body, a valve sea, the valve clack, the valve rod, valve gap and electric actuator etc, mainly with setting up the structural style that the valve clack adoption bipyramid facial features above the disk seat combines, constitute with lower taper surface by the integrative last taper surface that links to each other promptly, and it is lighter than taper surface tapering down to go up toper face cone degree, the port is equipped with sealed face of awl mouthful form and last taper surface sealing contact on the disk seat again, but with the lower contactless relation of taper surface, this kind of structural style is favorable to improving the control range value of the discharge coefficient and the flow of valve, the vertical pulling formula electric two way valve that avoids traditional structure the valve flow coefficient appears and less and arouse when valve exit end flow is not enough, must improve that the velocity of flow of medium remedies the defect that the flow is not enough among the pipe -line system through the output who improves the water pump, consequently better reduction system energy consumption, also reduce user's energy loss.
