Abstract
The invention discloses a method and device for preventing an irrigation electronic control valve from being out of operation. A water channel in a magnetic valve is isolated from an upper cavity body through an elastic packing cup which is placed between a valve element assembly and a valve cavity, the upper cavity body is connected with a control channel, and meanwhile a whole control mechanism is isolated from a water route through a pre-guiding film sheet to prevent sediment and other sundries from affecting the operation of the control mechanism and to improve the work reliability of the electronic control valve. Due to the fact that the pre-guiding film sheet is used for isolating the whole control mechanism from water, the sediment and other sundries can be prevented from affecting the normal work of the control mechanism. The bore diameter of an outer circulation channel is enlarged, so that the water containing the sediment and the sundries flows successfully, the process that the water flows in and out of the valve cavity is accelerated, and a switch of the electronic control valve is controlled fast and flexibly. The water inlet process and the water outlet process of the upper cavity body are respectively controlled through a double-direction micromotor, in each water draining process, the water inside the valve cavity can be drained thoroughly, the sediment and the sundries in the upper cavity body are brought away, the phenomenon that a large amount of sediment is deposited inside the valve cavity is avoided, and the working reliability and the working stability of the electronic control valve are improved.
