The invention discloses a multiple-directional reversing valve for forklifts. The multiple-directional control valve comprises an oil inlet valve plate, multiple reversing valve plates and an oil return valve plate; the reversing valve plates are arranged between the oil inlet plate and the oil return valve plate; the oil inlet valve plate, the reversing valve plates and the oil return valve plate are of an integral structure; an oil inlet P is arranged in the oil inlet valve plate, an oil return joint is arranged on the oil return valve plate, and an oil return port T is arranged in the oil return joint; each of the reversing valve plates is provided with one or two working oil ports; each of the reversing valve plates is inserted with a valve stem, and one end of each valve stem extends out of the corresponding reversing valve plate. The multiple-directional reversing valve has the advantages that risk of oil leakage can be lowered, operational reliability of the valve can be improved, convenience in maintenance is achieved, machining technique is simplified, machining cost is lowered, and the like.
Description
Technical field [0001] The invention relates to a multi-way valve, in particular to a multi-way reversing valve for forklifts. Background technique [0002] Multi-way reversing valves are widely used in forklifts and other mechanical equipment, mainly to meet the one-way lock of the actuator. The multi-way valve integrates the hydraulic control check valve into the working body, has a compact structure and a long working life, while reducing the layout of the hydraulic system pipeline. [0003] At present, the existing multi-way directional valve mostly adopts a split structure. Such as Figure 5 It is the outline drawing of the multi-way reversing valve in the prior art. Such as Figure 5 It can be seen that this existing multi-way reversing valve is composed of an oil inlet valve plate 1, a plurality of reversing valve plates 2 and an oil return valve plate 3. Between two adjacent valve plates, a plate In order to seal the intermediate gasket 4, multiple inter-plate gaskets are ...
