Description
Technical field
The utility model relates to a kind of application hydraulic system of flow divider-combiner, specifically the oil hydraulic circuit of a kind of flow divider-combiner and stop valve united application.
Background technique
In hydraulic circuit, adopt flow divider-combiner, can reasonable distribution two rates of discharge, regulate the motion speed of two executive components, realize the synchronous requirement of load operation; Its working principle is: promote moving left and right of flow distributing and collecting valve core by the pressure difference of two outlet (combiner valve is filler opening) oil circuits, and then adjust the size of hydraulic fluid port (combiner valve is filler opening), control being synchronized with the movement of two executive components.
But after employing flow divider-combiner; if operating mode needs operation executive component; when regulating synchronization error; the executive component oil circuit pressure then do not run reaches the setting value of system; flow distributing and collecting valve core can be promoted on the contrary to the end motion needing to run, this oil circuit closed, make the action of this executive component slowly or slack; be not easy to like this realize the independent adjustment to executive component, affect working efficiency.Sometimes, also need temporary changes pipeline to connect to regulate separately, operation brings inconvenience.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the oil hydraulic circuit of a kind of flow divider-combiner and stop valve united application, by connecting a stop valve between the outlet of flow divider-combiner, realize the isolated operation of executive component in flow distributing and collecting valve system, expand the application area of flow divider-combiner, convenient on-the-spot debugging efforts.
The utility model is by the following technical programs: the oil hydraulic circuit of a kind of flow divider-combiner and stop valve united application, comprises flow divider-combiner; Two outlets of described flow divider-combiner are connected with executive component respectively; It is characterized in that: between described flow divider-combiner two outlet, be connected with stop valve.
It is further: described executive component comprises oil hydraulic cylinder I and oil hydraulic cylinder II; An oil outlet of described flow divider-combiner is by a selector valve I connecting fluid cylinder pressure I, and another oil outlet of flow divider-combiner is by a selector valve II connecting fluid cylinder pressure II.
Described oil hydraulic cylinder I rodless cavity oil circuit is provided with Pilot operated check valve I, and the control chamber of Pilot operated check valve I is communicated with oil hydraulic cylinder I rod chamber; Described oil hydraulic cylinder II rodless cavity oil circuit is provided with Pilot operated check valve II, and the control chamber of Pilot operated check valve II is communicated with oil hydraulic cylinder II rod chamber.
Described selector valve I and selector valve II are three position four-way directional control valves.
Described stop valve is Non-follow control or Electronic control.
The utility model be mainly used in by flow divider-combiner control two executive components motion speed, realize in the synchronous system of load operation, its effect is: operating mode needs operation executive component, when regulating synchronization error, open stop valve, at this moment two outlets of flow divider-combiner are connected to the executive component needing motion simultaneously, the pressure of two of flow divider-combiner outlets are equal, and flow distributing and collecting valve core there will not be and moves left and right phenomenon, ensures the isolated operation smoothly of single executive component.
The utility model structure is simple, and realize movement position some in the synchronous executive component of quick adjustment, working efficiency is high, simple to operate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, flow divider-combiner; 2, stop valve; 3.1, selector valve I; 3.2, selector valve II; 4.1, Pilot operated check valve I; 4.2, Pilot operated check valve II; 5.1, oil hydraulic cylinder I; 5.2, oil hydraulic cylinder II.
Embodiment
Be below a specific embodiment of the present utility model, existing the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, the oil hydraulic circuit of a kind of flow divider-combiner and stop valve united application, flow divider-combiner 1 connects oil pump, fuel tank provides high pressure oil for system; Flow divider-combiner 1 one oil outlets connect selector valve I 3.1, selector valve I 3.1 control connection oil hydraulic cylinder I 5.1; Another oil outlet of flow divider-combiner 1 connects selector valve II 3.2, selector valve II 3.2 control connection oil hydraulic cylinder II 5.2; Be connected with normally closed stop valve 2 between flow divider-combiner 1 two outlet, stop valve 2 can select Non-follow control or Electronic control; Oil hydraulic cylinder I 5.1 rodless cavity oil circuit is provided with Pilot operated check valve I 4.1, and the control chamber of Pilot operated check valve I 4.1 is communicated with oil hydraulic cylinder I 5.1 rod chamber; Oil hydraulic cylinder II 5.2 rodless cavity oil circuit is provided with Pilot operated check valve II 4.2, and the control chamber of Pilot operated check valve II 4.2 is communicated with oil hydraulic cylinder II 5.2 rod chamber; Three position four-way directional control valve selected by selector valve I 3.1 and selector valve II 3.2.
Under system normal operation, stop valve 2 is in normally off, flow divider-combiner 1 reasonable distribution two rates of discharge, regulates the motion speed of two executive components, realizes the synchronous requirement of load operation; When system debug or special operation condition demand, when needing oil hydraulic cylinder I 5.1 or oil hydraulic cylinder II 5.2 isolated operation, open stop valve 2, reversing valve operated I 3.1 or selector valve II 3.2, single cylinder action can be realized smoothly.The feature of the utility model compared with original technology: the application area widening flow divider-combiner, practical.Owing to adding stop valve in flow divider-combiner two outlets, the demand of executive component isolated operation in practical operation can be met.
