Abstract
The invention relates to a multichannel conversion valve (CDB2-F20 valve) comprising an oil inlet valve body part, a lift valve body part, a tilted self-locking valve body part, and the like, wherein when hydraulic oil enters a threaded port of the oil inlet valve body part, a flow dividing slide valve, a flow dividing pressure spring and a flow dividing orifice plug are pushed to move left so that the hydraulic oil flows to a redirector connector assembly and also flows to a diversion safety valve; when hydraulic pressure inside the lift valve body part needs more, the diversion safety valve is downwards regulated so as to stop the hydraulic oil entering, and a similar way is on the contrary; and when the pressure of the hydraulic oil is overhigh, a main overflow valve is automatically opened, the hydraulic oil flows to the main overflow valve, thus the normal work and the service life of the multichannel conversion valve (CDB2-F20 valve) are ensured. The invention has small valve body volume, high intensification degree, convenient installation and maintenance and long service life.
