The achievement of the objects, functional features and advantages of the present invention will be further described with reference to the accompanying drawings, in conjunction with the embodiments.
Detailed Description
Referring to fig. 1, the hydraulic system parallel connection device based on tesla valve of the present invention includes two liquid inlets 1, where the two liquid inlets 1 are used for respectively feeding liquid; i.e. the inlet oil.
The liquid inlet 1 is communicated with the Tesla valves 2 through pipelines, and the Tesla valves 2 communicated with the two liquid inlets 1 are arranged oppositely; the application of the Tesla valve 2 has special significance for the invention, wherein the main reason is that the Tesla valve 2 can dredge the unidirectional circulation of the pressure oil and can play a role in inhibiting the flow direction of the recoil pressure oil; because of the valve body characteristic, the flow direction inhibiting function can not cause destructive impact on components, and the service life of the device is greatly prolonged. Through experiments, for the concrete setting form of the invention, the one-way valve has no practical application function and value, and the Tesla valve 2 can well solve the problem of oil recoil.
The tail ends of the two Tesla valves 2 are connected with a tee joint through pipelines, and the tee joint is respectively communicated with the pressure regulating chamber 3 and the liquid discharge pipeline 6 through pipelines;
the pressure regulating chamber 3 is internally provided with two pressure supplementing pipelines 5, and the two pressure supplementing pipelines 5 are respectively arranged at two sides of the pressure regulating chamber 3 and are in cross connection with the two liquid discharge pipelines 6.
The pressure regulating chamber 3 is slidably provided with a sealing slide block 4, the sealing slide block 4 is in mechanical sealing sliding connection with the pressure regulating chamber 3, and the width of the sealing slide block 4 is corresponding to the pressure supplementing pipeline 5.
Further, the communication position of the tee joint and the pressure regulating chamber 3 is positioned at the upper part of the pressure regulating chamber 3;
the pressure supplementing pipelines 5 are respectively arranged at two sides of the bottom of the pressure regulating chamber 3.
That is, when the pressure of the one-end tesla valve 2 entering the pressure regulating chamber 3 is higher than that of the other side, the pressure oil pushes the seal slider 4 to leak out of the pressure supplementing pipe 5 on the same side and to block the pressure supplementing pipe 5 on the opposite side, and simultaneously, the pressure supplementing pipe 5 on the same side supplements the pressure of the liquid discharge pipe 6 on the opposite side.
Further, an assembling protrusion is arranged on the side edge of the sealing sliding block 4, an assembling groove is formed in the pressure adjusting cavity 3 corresponding to the assembling protrusion, and a spring is arranged between the assembling groove and the assembling protrusion.
While the fundamental and principal features of the invention and advantages of the invention have been shown and described, it will be apparent to those skilled in the art that the invention is not limited to the details of the foregoing exemplary embodiments, but may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
