Abstract
The utility model discloses a kind of protecting against shock of one-way hydraulic motor and anti-reverse pressurized oil system, it is characterized in that: comprise for system the oil hydraulic pump of power is provided, the relief valve of safety protection is provided for system, two four-way electromagnetic reversing valves, one-way hydraulic motor and one-way valves; Wherein: an inlet opening of described two four-way electromagnetic reversing valves is connected with oil hydraulic pump, and another inlet opening is connected with fuel tank, two delivery outlets of described two four-way electromagnetic reversing valves are connected with return opening with the filler opening of one-way hydraulic motor respectively; Described relief valve is connected with oil hydraulic pump; Described one-way valve and one-way hydraulic motors connect.By adopting technique scheme, the utility model utilizes one-way valve oil circuit to avoid the hydraulic shock causing oil hydraulic motor when solenoid directional control valve cuts out, and can prevent the counterrotating of oil hydraulic motor, and therefore the utility model has better Security; There is the simple feature of structure simultaneously.
Description
Technical field
The utility model relates to hydraulic system technical field, particularly relates to a kind of protecting against shock of one-way hydraulic motor and anti-reverse pressurized oil system.
Background technique
One-way hydraulic motor in current most of hydraulic system, generally, oil hydraulic motor filler opening connects selector valve, the break-make of oil circuit control, and oil outlet directly connects fuel tank, when oil passage disconnects suddenly, can cause very large hydraulic shock to oil hydraulic motor; Or adopt the buffer loop of one-way valve and relief valve composition, but still there is certain hydraulic shock.
Model utility content
The technical problems to be solved in the utility model is: provide a kind of protecting against shock of one-way hydraulic motor and anti-reverse pressurized oil system; Utilize one-way valve oil circuit to avoid the hydraulic shock causing oil hydraulic motor when solenoid directional control valve cuts out, and the counterrotating of oil hydraulic motor can be prevented.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
The protecting against shock of one-way hydraulic motor and an anti-reverse pressurized oil system, is characterized in that: comprise for system the oil hydraulic pump of power (1) is provided, the relief valve (2) of safety protection is provided for system, two four-way electromagnetic reversing valves (3), one-way hydraulic motor (4) and one-way valves (5); Wherein: an inlet opening of described two four-way electromagnetic reversing valves (3) is connected with oil hydraulic pump, another inlet opening is connected with fuel tank, and two delivery outlets of described two four-way electromagnetic reversing valves (3) are connected with return opening with the filler opening of one-way hydraulic motor (4) respectively; Described relief valve (2) is connected with oil hydraulic pump (1); Described one-way valve (5) is connected with one-way hydraulic motor (4).
The advantage that the utility model has and good effect are: by adopting technique scheme, the utility model utilizes one-way valve oil circuit to avoid the hydraulic shock causing oil hydraulic motor when solenoid directional control valve cuts out, and the counterrotating of oil hydraulic motor can be prevented, therefore the utility model has better Security; There is the simple feature of structure simultaneously.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model;
Wherein 1, oil hydraulic pump; 2, relief valve 2; 3, two four-way electromagnetic reversing valves; 4, one-way hydraulic motor; 5, one-way valve.
Embodiment
For model utility content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the protecting against shock of one-way hydraulic motor and an anti-reverse pressurized oil system, comprise for system provides the oil hydraulic pump 1 of power, provides relief valve 2, two four-way electromagnetic reversing valves 3, one-way hydraulic motor 4 and one-way valves 5 of safety protection for system; Wherein: an inlet opening P of described two four-way electromagnetic reversing valves 3 is connected with oil hydraulic pump, another inlet opening T is connected with fuel tank, and two delivery outlets A, B of described two four-way electromagnetic reversing valves 3 are connected with return opening with the filler opening of one-way hydraulic motor 4 respectively; Described relief valve 2 is connected with oil hydraulic pump 1; Described one-way valve 5 is connected with one-way hydraulic motor 4.When one-way hydraulic motor 4 works, two four-way electromagnetic reversing valve 3 power-off suddenly, the oil feeding line of one-way hydraulic motor 4 disconnects, one-way hydraulic motor 4 into and out of hydraulic fluid port be enclosed space, due to load inertia, one-way hydraulic motor 4 is rotated further, the inlet pressure of one-way hydraulic motor 4 is caused to reduce, oil outlet pressure increase, now, the oil at one-way hydraulic motor 4 oil outlet place flows to the filler opening of one-way hydraulic motor 4 by one-way valve 5, only need overcome the cracking pressure of one-way valve 5, therefore prevent the hydraulic shock of one-way hydraulic motor 4.When the power-off of two four-way electromagnetic reversing valves 3, when one-way hydraulic motor 4 quits work, in the minor loop that one-way hydraulic motor 4 and one-way valve 5 are formed, one-way valve 5 prevents the reverse flow of fluid, thus prevent the counterrotating of one-way hydraulic motor 4, in order to avoid destroy some requirement of actual working condition.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
