The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
Referring to fig. 1, the hydraulic system parallel connection device based on tesla valves comprises two liquid inlets 1, wherein the two liquid inlets 1 are used for respectively feeding liquid; i.e. the inlet oil.
The liquid inlets 1 are 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 is of special significance for the invention, wherein the main reason is that the Tesla valve 2 can dredge the one-way circulation of the pressurized oil and can play a role in restraining the flow direction of the backflushed oil; due to the characteristics of the valve body, the flow direction inhibiting function of the valve body cannot cause destructive impact on components, and the service life of equipment is greatly prolonged. Through experiments, for the specific arrangement 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 adjusting chamber 3 and the liquid drainage pipeline 6 through pipelines;
and two pressure supplementing pipelines 5 are arranged in the pressure adjusting chamber 3, and the two pressure supplementing pipelines 5 are respectively arranged at two sides of the pressure adjusting chamber 3 and are in cross connection with the two liquid discharge pipelines 6.
The pressure adjusting chamber 3 is internally provided with a sealing slide block 4 in a sliding manner, the sealing slide block 4 is in mechanical sealing sliding connection with the pressure adjusting chamber 3, and the width of the sealing slide block 4 is arranged corresponding to the pressure supplementing pipeline 5.
Further, the communication position of the tee joint and the pressure adjusting chamber 3 is positioned at the upper part of the pressure adjusting chamber 3;
the pressure supplementing pipelines 5 are respectively arranged at two sides of the bottom of the pressure adjusting chamber 3.
That is, when the pressure of the tesla valve 2 entering the pressure adjusting chamber 3 at one end is higher than that at the other end, the pressure oil pushes the sliding block 4 to leak out of the pressure supplementing pipeline 5 at the same side, and blocks the pressure supplementing pipeline 5 at the opposite side, and the pressure supplementing pipeline 5 at the same side supplements pressure to the liquid discharging pipeline 6 at the opposite side.
Furthermore, the side of the sliding block 4 is provided with an assembling bulge, an assembling groove is formed in the pressure adjusting chamber 3 corresponding to the assembling bulge, and a spring is arranged between the assembling groove and the assembling bulge.
While there have been shown and described what are at present considered the fundamental principles and essential features of the invention and its advantages, 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 is capable of 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 description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
