Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention will be further described;

[0010] In the figure, a multi-way reversing valve (CDB2-F20 valve) is composed of an oil inlet valve body part 1, a lifting valve body part 2, an inclined self-locking valve body part 3, and an oil return valve body part 4. It is characterized in that: the left side of the entire valve body is provided with an oil inlet valve body part 1, and the right side of the oil inlet valve body part 1 is provided with a lifting valve body part 2, an inclined self-locking valve body part 3, and an oil return valve body part 4; In the oil inlet valve body part 1, a main overflow valve 12 is provided at the lower end of the right side, a diverter slide valve 9 is provided at the upper left part, and a diverter throttle plug 10 is provided at the right part of the inner cavity of the diverter slide valve 9, and a diverter throttle plug 10 is provided at the left part. The part is provid...

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.

Description

Technical field: [0001] The invention relates to a multi-way reversing valve, which is a hydraulic component and is mainly suitable for hydraulic systems such as forklifts and other hoisting and transporting machinery, walking machinery, agricultural machinery, etc., and implements centralized control of multiple actuators. Background technique: [0002] At present, the multi-way reversing valve in China has a large valve body, low degree of intensification, and difficult installation and maintenance; small oil passages are easy to block, large pressure loss, high energy consumption, easy heating of the system, and low service life. Affect the normal production of users and bring certain economic losses. Invention content: [0003] The purpose of the present invention is to provide a multi-way directional valve, which can well overcome the problems existing in the current domestic multi-way directional valve, the purpose of the present invention is achieved in this way, a ...
