The electro-liquid commutation valve consists of electromagnetic commutation valve and a hydraulic replacement valve, wherein the electromagnetic commutation valve begins with the forefront of the electromagnetic replacement valve, that is, used to change the direction of the hydraulic replacement valve to control the pressure oil; the liquid exchange valve is used as the main valve, its work The position is determined accordingly by the working position of the electromagnetic commutation valve. The electro-hydraulic replacement valve is divided into control oil and oil-based, internal control, internal control, external control, external control, externally leaking. For the external control valve, since the control oil is introduced separately from the oil passage outside the electric metal, it is not in use, no matter whether there is any problem, no matter whether it is internal leakage or leakage. For the electro-hydraulic displacement valve for the in-line control mode, since the p-opening of the pilot valve and the P port of the main valve is communication, if the position is made in the middle position, such as M, h, k, etc. Base function, the main oil path cannot provide the main valve core to the control oil path to provide the main valve core to the control oil. Therefore, it is not advisable to take this internal control electro-hydraulic reigning valve having a median unloading function. If you want to take this form, you must pay a pre-control pressure valve at the time of the application, so that in the unloading state still has a certain control hydraulic pressure, it is sufficient to manipulate the main valve core, otherwise it will not work properly, that is, the pilot valve The main valve cannot be reversed.
