Description

A kind of flushing valve
Technical field
The utility model relates to hydraulic transmission technology field, particularly relates to a kind of flushing valve that carries the Flow-rate adjustment formula of shuttle valve and pressure self balancing.
Background technique
Modern times are in the hydraulic element of high voltage and high power, for improving the working life of its hydraulic element, usually need increase washing capacity at its element, reduce its inside temperature, increase oil viscosity, reduce the friction factor between each friction pair, increase the working life of each element.Increase washing capacity at hydraulic element, must need the flushing oil of the certain flow under the certain pressure.Common flushing oil, generally the return opening from system inserts hydraulic element by pipeline.The flow of return opening, pressure like this, the design of pipeline directly influences the washing capacity of hydraulic element, and requires the user that the understanding of hydraulic pressure knowledge is wanted many.
The model utility content
Technical problem to be solved in the utility model provides a kind of flushing valve, can realize the Flow-rate adjustment of pressure self balancing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of flushing valve is provided, comprises entrance, shuttle valve, equilibrated valve and throttle valve, described entrance links to each other with shuttle valve, and described shuttle valve is used for selecting the low pressure oil of hydraulic element; The outlet of described shuttle valve links to each other with the entrance of equilibrated valve, and described equilibrated valve is used for regulating pressure; The outlet of described equilibrated valve links to each other with the entrance of throttle valve, and described throttle valve is used for regulating flow.
Described entrance links to each other with the oil inlet and outlet of hydraulic element.
Beneficial effect
Owing to adopted above-mentioned technological scheme, the utility model compared with prior art, have following advantage and good effect: entrance hydraulic oil of the present utility model is introduced from the oil inlet and outlet of element, select the low pressure oil of hydraulic element to introduce by carrying shuttle valve, and reach demand pressure by the pressure balance spool, again by Flow-rate adjustment, thereby reach under the condition of no external hydraulic oil, realization improves the working life of hydraulic element to the washing capacity of hydraulic element.
The utility model can be realized the integrated form setting with hydraulic element, simplifies user's installation difficulty, reduces wrong generation.Automatically select the low pressure oil sources by the shuttle valve that carries, solve the element clockwise and anticlockwise, do not influence the function of use of element.Can realize the pressure self balancing by the utility model, reduce compression shock to the damage of element, and stability of flow be adjustable, can be fit to the applying working condition of different elements.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Mode of execution of the present utility model relates to a kind of flushing valve, as depicted in figs. 1 and 2, comprises entrance, shuttle valve 1, equilibrated valve 2 and throttle valve 3, and described entrance links to each other with shuttle valve 1, and described shuttle valve 1 is used for selecting the low pressure oil of hydraulic element; The outlet of described shuttle valve 1 links to each other with the entrance of equilibrated valve 2, and described equilibrated valve 2 is used for regulating pressure; The outlet of described equilibrated valve 2 links to each other with the entrance of throttle valve 3, and described throttle valve 3 is used for regulating flow.Wherein, described entrance links to each other with the oil inlet and outlet of hydraulic element.
Working principle of the present utility model is as follows: introduce hydraulic oil from the oil inlet and outlet of hydraulic element, automatically (P is pressure to select the little hydraulic oil of PS value by shuttle valve, S is work area), enter the pressure balance spool and reach the requirement pressure range, flow into hydraulic element by flow control valve again, play washing capacity.
Be not difficult to find that the utility model can be realized the integrated form setting with hydraulic element, simplify user's installation difficulty, reduce wrong generation.Automatically select the low pressure oil sources by the shuttle valve that carries, solve the element clockwise and anticlockwise, do not influence the function of use of element.Can realize the pressure self balancing by the utility model, reduce compression shock to the damage of element, and stability of flow be adjustable, can be fit to the applying working condition of different elements.

Claims (2)

1. flushing valve comprises entrance, shuttle valve (1), equilibrated valve (2) and throttle valve (3), it is characterized in that, described entrance links to each other with shuttle valve (1), and described shuttle valve (1) is used for selecting the low pressure oil of hydraulic element; The outlet of described shuttle valve (1) links to each other with the entrance of equilibrated valve (2), and described equilibrated valve (2) is used for regulating pressure; The outlet of described equilibrated valve (2) links to each other with the entrance of throttle valve (3), and described throttle valve (3) is used for regulating flow.
