Abstract
The utility model discloses a reversing return circuit using a stroke valve to control a hydraulic change-over valve. The reversing return circuit using the stroke valve to control the hydraulic change-over valve comprises a hydraulic pump, the stroke valve and a reducing valve. The hydraulic pump is connected with the hydraulic change-over valve. The stroke valve, the hydraulic change-over valve and the reducing valve are connected in sequence. The reducing valve is connected on an oil way between the hydraulic pump and the hydraulic change-over valve. An overflow valve is connected on the left side of the oil way above the hydraulic pump, and an electromagnetic exchange valve is connected on the right side of the oil way above the hydraulic pump. The reversing return circuit using the stroke valve to control the hydraulic change-over valve is simple in structure, small in reversing impact force, high in direction change accuracy, stable in direction exchange and better in performance.
Description
Technical field
The utility model relates to a kind of commutation loop, relates in particular to a kind of commutation loop of utilizing stroke valve control hydraulicchange-over valve.
Background technique
Commutation loop is used for the oily flow path direction of controlled hydraulic system, thereby changes the moving direction of executive component, requires commutation loop should have higher commutation precision, sensitive reversing degree and commutation stationarity for this reason.Commonly used is the solenoid valve commutation loop at present, and medium taches such as sensitive switch, pressure relay need be passed through in this loop; Loop structure is provided with complexity, and reversing impact power is big; The commutation precision is low, and it is not too steady to commutate, and functional reliability is relatively poor.
The model utility content
In order to solve the existing deficiency of above-mentioned technology, the utility model provides a kind of commutation loop of utilizing stroke valve control hydraulicchange-over valve.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of commutation loop of utilizing stroke valve control hydraulicchange-over valve, comprise oil hydraulic pump, stroke valve, reduction valve, and oil hydraulic pump is connected with hydraulicchange-over valve; Stroke valve, hydraulicchange-over valve and reduction valve order are connected successively; Reduction valve is connected on the oil circuit between oil hydraulic pump and the hydraulicchange-over valve; The and arranged on left and right sides of oil hydraulic pump top oil circuit is connecting relief valve and solenoid directional control valve respectively.
The utility model is simple in structure, reversing impact power is little, commutation precision height, commutation steadily, performance is better.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, oil hydraulic pump; 2, relief valve; 3, solenoid directional control valve; 4, reduction valve; 5, stroke valve; 6, hydraulicchange-over valve.
Embodiment
As shown in Figure 1, the utility model mainly comprises oil hydraulic pump 1, relief valve 2, solenoid directional control valve 3, reduction valve 4, stroke valve 5 and hydraulicchange-over valve 6.
Oil hydraulic pump 1 is connected with hydraulicchange-over valve 6.Stroke valve 5, hydraulicchange-over valve 6 and reduction valve 4 orders are connected successively.Reduction valve 4 is connected on the oil circuit between oil hydraulic pump 1 and the hydraulicchange-over valve 6.The and arranged on left and right sides of oil hydraulic pump 1 top oil circuit is connecting relief valve 2 and solenoid directional control valve 3 respectively.
The utility model is with motor-driven, the hydraulic operated commutation loop of stroke valve as pilot valve control hydraulicchange-over valve.Utilize the collision block control run valve core on the piston to move, change the oily flow path direction of pilot pressure oil, thereby control hydraulicchange-over valve movement direction to realize the working connection commutation, moves positive and negative two directions of piston.Solenoid directional control valve is used for making system unloaded, when energising, and the pump off-load, the oil hydraulic cylinder stop motion, the commutation of this loop is reliable, stable performance.
