The invention relates to a throttle pipe for a household air-conditioner, which comprises a tubular valve body, wherein a left static valve core, a right static valve core and a movable valve core arearranged in the valve body. The throttle pipe is characterized in that the movable valve core is provided with a first pore and a second pore which are both inclined pores; a left end outlet of the first pore is arranged on the axes of the movable valve core, while a right end outlet of the second pore is arranged on the axes of the movable valve core; the left static valve core is only providedwith a left pore channel passing through the axes; and the right static valve core is only provided with a right pore channel passing through the axes. Paths of fluid flowing from two ends of the valve body are staggered, and are not in the same axial line, thereby changing the situation that paths of a refrigerating fluid of the prior throttle pipe flowing through the two ends of the valve body are overlapped; moreover, under the condition that the movable valve core moves in the middle, the refrigerating fluid can pass through the two pores on the movable valve core, so that the refrigerating fluid passing through the movable valve core has larger flow rate, and the throttle pipe has large variation in flow rate during the moving process of the movable valve core.
