Description
Technical field
The utility model relates to the hydraulics field, relates in particular to a kind of integrated type that is used for engineering machinery and farm machinery and joins selector valve more.
Background technique
The selector valves that join are widely used in the hydraulic control system of engineering machinery and farm machinery more.In the hydraulic control system of small engineering machinery, it is quite extensive that split blade type joins the selector valve application more at present, and its structure and work characteristics are: need sealing between the valve block, the junction plane of two groups of valve blocks needs fine finishing, and the requirement on machining accuracy of sealed groove is high; Sealing long-term work between the valve block was lost efficacy under the higher environment of temperature easily, caused hydraulic oil to leak outside, befouling environment; Combine by stay bolt between the valve block, factor such as fastening inhomogeneous, bolt creep also can cause seal failure; Each joins valve block function opposite independent, and two actuator ports share an one-way valve, and join valve assembly has severally more, just needs several one-way valves.Therefore split blade type joins selector valve more and exists: processing charges is high; Leak outside easily between valve block; Volume is big, and heaviness is not easy to defectives such as vehicle layout.
Summary of the invention
The utility model is exactly for the split blade type that solves existing technology joins the valve block processing charges height that selector valve exists more, leaks outside easily between valve block, and volume is big, heavy, is not easy to the problem that vehicle is arranged; Provide a kind of integrated type to join selector valve more; Have simple in structure, use sealing reliable, volume is little, in light weight, advantage easy to install and use.
To achieve these goals, the utility model adopts following technological scheme:
Integrated type joins selector valve more, comprises switching-over valve body, valve rod, the valve rod resetting-mechanisms of joining more; Join in the switching-over valve body is provided with oil suction chamber and one-way valve more; The valve rod resetting-mechanism connects with the valve rod tail end, is provided with the one-way valve oil duct that perforation respectively joins selector valve behind the homonymy one-way valve of many couplet switching-over valve bodies, and one-way valve is located between oil suction chamber and the one-way valve oil duct; Valve rod is provided with and the corresponding grooves of hydraulic pressure oil duct that join the switching-over valve body more, and the switching-over valve body both sides that join are provided with actuator port more.Oil duct communicates with actuator port through the groove on the valve rod when valve rod is in commutation position, to export hydraulic oil to operation mechanism.
Said one-way valve oil duct runs through and respectively joins selector valve, joins shared this oil duct of selector valve more.
The back oil roads that join switching-over valve body both sides are communicated with the annular back oil road of formation more.
The switching-over valve bodies that join are provided with safety valve more.
The switching-over valve bodies that join are provided with the overload Fill valve more.
The switching-over valve bodies that join are provided with the gap bridge joint more.
The working principle of the utility model: the oil duct of the utility model can communicate with actuator port through the groove on the valve rod when valve rod is in commutation position, to export hydraulic oil to operation mechanism.Valve rod has three positions with respect to the switching-over valve body, and the break-make of controlling the hydraulic pressure oil duct is come the Control work mechanism action thereby armrest is moving or guide's hydraulic pressure commutates; Spring reset mechanism guarantees that valve rod automatically replies meta after the external force cancellation.If each valve rod all mediates, then be down " Y " shape meta back oil road through the cross section in the middle of the valve body and directly flow to the return opening oil sump tank from the next hydraulic oil of the filler opening of oil suction chamber, perhaps flow to next hydraulic parts through the gap bridge joint.Make it be in commutation position (no matter push or pull out) if handle valve rod, then the meta back oil road in the middle of the valve body is cut off, and the groove on the valve rod is connected one-way valve oil duct and actuator port A, actuator port B simultaneously; This moment, hydraulic oil was opened one-way valve, got into the one-way valve oil duct, got into actuator port through the groove on the valve rod again; Finally flow to equipment; Then through the hydraulic fluid port of valve body opposite side, the groove on valve rod is got back to the annular back oil road of valve body in its oil return, final oil sump tank.The utility model; With the shared one-way valve of the homonymy hydraulic fluid port that joins selector valve more, one-way valve oil duct and work oil duct and oil return oil duct are all designed in a plane, how much no matter join number; Whole hydrovalve only needs two one-way valves; Simplified valve body structure, valve volume and weight saving, cost reduces.Prolong the oil duct behind the one-way valve, ally the communists more and use this oil duct, drainback passage prolongation in valve body both sides communicates, and forms ring shaped oil passage, has simplified the oil duct layered structure of valve body, and has improved casting manufacturability.
The beneficial effect of the utility model: shared one-way valve of the utility model homonymy hydraulic fluid port and one-way valve oil duct, whole hydrovalve only needs two one-way valves, and be simple in structure; And the hydraulic pressure oil duct that makes entire product is easy to arrange, and is structural and manufacturability is better, alleviated the volume and the weight of product greatly, reduced cost.
