Abstract
The utility model relates to an improved high-pressure integrated multidirectional reversing valve which comprises a reversing valve and an integrated valve body and is characterized in that: an oil inlet pipe and an oil outlet pipe, through which hydraulic oil can pass, are arranged in the integrated valve body; the reversing valve, a main overflow valve and a hydraulic lock are arranged between the oil inlet pipe and the oil outlet pipe in turn; a safety valve is arranged between the oil inlet pipe and the reversing valve; a bidirectional buffer reversing valve is arranged between the reversing valve and the main overflow valve; a bypass flow overload valve is arranged between the main overflow valve and the hydraulic lock; an elastic part is arranged between the reversing valve and the bidirectional buffer reversing valve; and a sealing device is arranged between the main overflow valve and the bypass flow overload valve. The improved high-pressure integrated multidirectional reversing valve has the advantages that the integrated structure is adopted; the sealing property is excellent; the hydraulic resistance is reduced; the pressure loss is reduced; the system heating is reduced; the structure is compact; the processing parts are reduced; the production cycle is shortened; the production cost is lowered; and the production efficiency is increased.
Description
Technical field
The utility model relates to a kind of multiple directional control valve, relates in particular to a kind of improved high pressure integral multi-way reversing valve.
Background technique
On the machinery such as engineering machinery, building machinery, adopted the hydraulic pressure withstand leg in a large number in modern times, wherein position control valve is crucial hydraulic element; The quality of its performance will directly have influence on the performance of whole main frame, and the tradition that on hydraulic hoist, the adopts selector valve of getting off is generally the split blade type machine and adds runner, exist oil impregnate between sheet, liquid resistance and the pressure loss is big, energy consumption is high, system is prone to problems such as heating; And present selector valve is many owing to component, and manufacturing procedure is complicated, and production management is loaded down with trivial details; Process-cycle is long, makes manufacturing enterprise's manufacture cost high, and quality of product can not get guaranteeing; For addressing the above problem, the spy provides a kind of new technological scheme.
The model utility content
The purpose of the utility model provides a kind of improved high pressure integral multi-way reversing valve.
The technological scheme that the utility model adopts is:
A kind of improved high pressure integral multi-way reversing valve; Comprise selector valve and integrated type valve body; Be provided with in-line and the vent line that hydraulic oil is passed through in the said integrated type valve body, be provided with selector valve, main relief valve and hydraulic lock between said in-line and the vent line successively, be provided with safety valve between said in-line and the selector valve; Be provided with the bidirectional buffering selector valve between said selector valve and the main relief valve; Be provided with the shunting overload valve between said main relief valve and the hydraulic lock, be provided with elastic member between said selector valve and the bidirectional buffering selector valve, be provided with seal arrangement between said main relief valve and the shunting overload valve.
Said seal arrangement is a seal ring.
Said elastic member is spacing back-up ring.
The utility model has the advantages that: adopted monolithic construction, had excellent sealing performance, reduced the liquid resistance, reduced the pressure loss; Reduce system's heating, compact structure, processing accessories reduces; Manufacture cycle shortens, and has reduced cost of production, has improved manufacturing efficiency.
