Wherein: 1, safety valve valve gap two, 2, inserted valve one, 3, direction valve valve gap two, 4, inserted valve two, 5,3DT, 6,4DT, 7, direction valve valve gap one, 8, inserted valve three, 9, safety valve valve gap one, 10, inserted valve four, 11, overflow valve valve gap two, 12, check valve valve gap two, 13, check valve valve gap one, 14, overflow valve valve gap one, 15,2DT, 16,1DT, 17, inserted valve five, 18, inserted valve six, 19, inserted valve seven, 20, inserted valve eight.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Fig. 1 is a structural representation of the present invention, is made up of rodless cavity and rod chamber among the figure, and described rodless cavity is by valve valve gap 21 closure valve valve gaps 23 are installed, inserted valve 1 connects inserted valve 24, overflow valve valve gap 2 11, check valve valve gap 2 12, inserted valve 5 17 connects inserted valve 6 18 and forms; Described rod chamber connects safety valve valve gap 1 by direction valve valve gap 1, and inserted valve 38 connects inserted valve 4 10, check valve valve gap 1, and overflow valve valve gap 1, inserted valve 7 19 connects inserted valve 8 20 and forms.Described inserted valve 24 connects inserted valve 38, and inserted valve 6 18 connects inserted valve 7 19, and inserted valve 24 is connected inserted valve 6 18 and inserted valve 7 19 with inserted valve 38.Described direction valve valve gap 23 is provided with 3DT5, and direction valve valve gap 1 is provided with 3DT6.Described overflow valve valve gap 2 11 is provided with 1DT16, and overflow valve valve gap 1 is provided with 2DT15.
Inserted valve 6 18 and inserted valve 7 19 are realized non-return valve function among the present invention, inserted valve 5 17 and inserted valve 8 20 are realized the overflow valve function, inserted valve 1 and inserted valve 4 10 are realized the safety valve function, and inserted valve 24 and inserted valve 38 are realized the reversal valve function of two-bit triplet.
The present invention mainly move into 3DT, 4DT must not when electricity, all not oil-feeds of rod chamber rodless cavity; That 3DT gets is electric, when 4DT must not electricity, the rodless cavity oil-feed, rod chamber is fuel-displaced, oil cylinder stretches out, and carries out the worker and advances function; 3DT must not electricity, 4DT gets when electric, and rodless cavity is fuel-displaced, the rod chamber oil-feed, and the oil cylinder withdrawal is carried out to pull out and is moved back function; When all when electric, realize rod chamber, the differential action of rodless cavity.Wherein the safe pressure of rod chamber and rodless cavity is realized by the safety valve valve gap.
The voltage-regulating system that the present invention is made up of inserted valve is applicable to the hydraulic system of big flow: inserted valve is simple in structure, and through-current capability is big, and action response is fast, and sealing property is good, accomplishes not have to leak, and contamination resistance is strong.Generally speaking, big flow system is accompanied by serious leakage problem, in order to address this problem, has used inserted valve especially, and the valve core structure that has benefited from its cone valve reaches leak free requirement.Now with inserted valve, overflow valve, the reversal valve combination can realize overflow respectively, commutation function, but reduced the spill losses of overflow valve again, speed system response time.
