An oil pressure reducing device

Abstract

The invention discloses an oil liquid pressure reduction device, and relates to the technical field of oil liquid pressure reduction devices. The device comprises a tank body, oil ports are symmetrically formed in the two ends of the tank body, the oil ports are used for being connected to an oil conveying pipeline, a first pressure reducing mechanism is arranged in the middle of the tank body, and the first pressure reducing mechanism is used for symmetrically dividing the tank body into two containing cavities; and second pressure reducing mechanisms are symmetrically arranged inside the twocontaining cavities correspondingly. According to the device, the pressure between an inlet and an outlet can be reduced through the pressure reducing mechanisms, the two-way pressure reduction can be realized due to the fact that the mechanisms are symmetric, and the mechanisms can be connected in a loop of a pressure hydraulic actuator in series; vibration caused by load sudden change is reduced, the device is particularly suitable for shock absorbers, mechanical vibration is reduced, and therefore smooth and normal operation of the machine is guaranteed.

Description

technical field [0001] The invention relates to the technical field of an oil decompression device, in particular to an oil circuit stability adjustment and shock absorbing device during mechanical movement. Background technique [0002] Decompression devices are widely used and are used in many structures to reduce pressure shocks. General oil decompression devices are divided into various types from the perspective of materials and structures, but most of them use different types of decompression mechanisms to adjust The oil pressure between the oil inlet and outlet is used to achieve the decompression effect. Generally, the structure of the pressure reducer is relatively complicated, the oil seal requirements are high, the process is complicated, it is not easy to maintain, and oil leakage may occur.

[0002] Decompression devices are widely used and are used in many structures to reduce pressure shocks. General oil decompression devices are divided into various types from the perspective of materials and structures, but most of them use different types of decompression mechanisms to adjust The oil pressure between the oil inlet and outlet is used to achieve the decompression effect. Generally, the structure of the pressure reducer is relatively complicated, the oil seal requirements are high, the process is complicated, it is not easy to maintain, and oil leakage may occur

And the manufacturing of the pressure reducing valve requires high precision and is expensive

[0003] Although the general pressure reducer solves the decompression required by most institutions, and the response is not slow, but the price is relatively high, and some institutions need a more rapid response decompression device to adjust the oil pressure to decompress, sometimes according to the external The environment requires a variety of adjustment methods. At this time, the general pressure reducing device and pressure reducing valve will not meet the requirements.
