Abstract
The utility model discloses a hydraulic steering control valve unit which is arranged in a hydraulic circuit and comprises a plurality of ball valve units which are connected together. Each ball valve unit comprises a plurality of ball valves which are connected with a hydraulic cylinder, wherein the two ends of the hydraulic cylinder are respectively connected with the ball valve units. Four-way ball valves are arranged in an upper oil circuit and a lower oil circuit. By adopting the technical scheme, since the steering control valve unit formed by the ball valves and the four-way ball valves is used for increasing and decreasing hydraulic steering elements and changing the direction of the hydraulic circuit, hydraulic elements in the hydraulic circuit can be increased and decreased and the direction of the hydraulic circuit can be changed without disassembling a pipeline. Thereby, the labor intensity of operators can be greatly reduced.
Description
Technical field
The utility model relates to a kind of fluid-link steering control valve group, and this valve group is particularly useful for being used for being assemblied in the novel hydraulic trailer.
Background technique
Hydraulic system is easy to transmit and configuration because its transmission force is big, and is extensive in industry, civilian sector application.In each parts is made, sealing, durability there are very high technical requirements, in hydraulic unit is made, extensively adopt at present---rolling technology has well solved the problem of circularity, roughness.Extensive use during particularly oil hydraulic cylinder is made.Hydraulic power tools can solve hydraulic pressure and make variety of issue.
In general, it is made up of two identical fluid cylinders of size, is full of water or oil in fluid cylinder.A piston that can slide is respectively arranged in two fluid cylinders, and piston connection piston rod slides and transmits strength.If add the hydraulic coupling of certain value in hydraulic pressure cavity, according to Pascal's law, piston is pushed up up by the pressure of liquid.Very big power be can obtain on the conversion piston by hydraulic coupling and power, wood veneer, oil expression, extraction weight, forging and pressing steel etc. suppressed with hydraulic press for this reason.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, proposes a kind of fluid-link steering control valve group of new structure, and it can detaching pipelines reaches and increases and decreases hydraulic element in the oil hydraulic circuit, changes the purpose of oil hydraulic circuit direction.
For achieving the above object, its concrete technological scheme is as following description:
A kind of fluid-link steering control valve group, be arranged among the oil hydraulic circuit, described control valve group comprises a plurality of ball valve group that link together, and described ball valve group comprises a plurality of ball valves that link together with oil hydraulic cylinder, and the two ends of described oil hydraulic cylinder are connected with described ball valve group respectively.
Further, preferred construction is, also is provided with four way ball valve, and described four way ball valve is arranged on up and down among two oil circuits.
Further, preferred construction is that the two ends of described ball valve group are connected with the big chamber of oil circuit and the oil circuit loculus of two oil circuits up and down.
The utility model is after having taked technique scheme, because the direction that the steering control valve group that ball valve and four way ball valve are formed is used to increase and decrease the fluid-link steering element and changes oil hydraulic circuit, increase and decrease hydraulic element in the oil hydraulic circuit thereby needn't detaching pipelines reach, change the purpose of oil hydraulic circuit direction.Alleviated labor intensity of operating personnel greatly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in detail, so that above-mentioned advantage of the present utility model is clearer and more definite.
Fig. 1 is the structural representation of the utility model fluid-link steering control valve group.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the structural representation of the utility model fluid-link steering control valve group, as shown in the figure, the utility model hydraulic control valve group is arranged among the oil hydraulic circuit, and, described control valve group comprises a plurality of ball valve group that link together, described ball valve group comprises a plurality of ball valves that link together with oil hydraulic cylinder, and the two ends of described oil hydraulic cylinder are connected with described ball valve group respectively.
Taked after the technique scheme, because ball valve is used to increase and decrease hydraulic element, thereby, can produce control action to hydraulic circuit.
As figure, oil hydraulic circuit loculus 21 and 23 and the big chamber 20 of oil hydraulic circuit and 22 between be connected with the ball valve group of forming by ball valve 1 and ball valve 2, and, similarly ball valve group also is provided with one, by the effect of this ball valve group, can regulate oil hydraulic circuit, from the increase and decrease hydraulic element.
In addition, we also are provided with four way ball valve 3 in this oil hydraulic circuit the inside, and described four way ball valve can be controlled the direction of oil hydraulic circuit, needn't detaching pipelines reach the technique effect that increases and decreases hydraulic element in the oil hydraulic circuit thereby reach.
The utility model is after having taked technique scheme, because the direction that the steering control valve group that ball valve and four way ball valve are formed is used to increase and decrease the fluid-link steering element and changes oil hydraulic circuit, increase and decrease hydraulic element in the oil hydraulic circuit thereby needn't detaching pipelines reach, change the purpose of oil hydraulic circuit direction.Alleviated labor intensity of operating personnel greatly.
Above-mentioned specific embodiment only is exemplary, and under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion drop in the protection domain of the present utility model.It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, are not to be used to limit the utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.
