Pressure valve debugging system

Abstract

The invention provides a pressure valve debugging system which comprises an oil supply way, a pressure-regulating test oil way and a pressure limiting oil way, wherein the oil supply way comprises at least one oil pump, and a first output node is arranged on an output pipeline of the oil pump; the pressure-regulating test oil way is connected with the first output node and is used for installing a valve to be pressured-regulated, and the pressure-regulating test oil way comprises a flow meter and pressure detecting access point which are connected between the valve to be pressured-regulated and the first output node in series; the pressure limiting oil way is connected with the first output node and is used for limiting the pressure of the pressure-regulating test oil way. The valve to be pressured-regulated is connected onto the pressure-regulating test oil way, and the oil supply way regulates the pressure and flow of the pressure-regulating test oil way, namely the valve to be pressured-regulated adopts a unified connection mode. During regulation, the pipeline does not need to be refitted, so that the amount of operation of pressure regulation is effectively relieved, the limiting problem of an operating space is solved, and the influence of disassembling and assembling the pipeline on the cleanliness of a hydraulic system. In addition, pressure-regulating operating personnel do not need to understand a working principle of a loop, and the requirement on the operating personnel is reduced.

Description

technical field [0001] The invention relates to the field of pressure regulating test devices for pressure valves, in particular to a pressure valve debugging system. Background technique [0002] The functions of hydraulic systems such as large-tonnage cranes are becoming more and more perfect, and the flow and pressure of different circuits are different. Pressure valves such as relief valves and pressure reducing valves of different specifications are often used to limit pressure. Whether each overflow valve and pressure reducing valve can accurately adjust the pressure of each pressure valve according to the design has a great influence on the normal operation of the crane. In addition, the pressure drop of the pressure valve is different under different flow rates. In order to adjust the pressure valve accurately, an appropriate flow rate must be provided. [0003] Due to the relatively simple functions of earlier hydraulic systems such as cranes, there are relatively ...

AI Technical Summary

Problems solved by technology

However, as the functions of hydraulic systems such as cranes are becoming more and more perfect, the number of relief valves and pressure reducing valves that need to be adjusted is increasing, and the problem of continuing to use the method of adjusting the pressure of the pressure valve during the actual product debugging process has gradually become prominent.

[0004] First of all, in debugging products, different pressure valves are connected in different ways in different circuits, and the adjustment methods of each pressure valve are also different, so the operator is required to have a certain understanding of the principles of each pressure valve and the circuit it is connected to, otherwise Unable to complete pressure regulation

Secondly, in the commissioning of the product, limited by the installation position of the pressure valve, surrounding pipelines and other components, there is not enough space for the wrench, which is not easy to operate

Thirdly, some pressure valves can directly adjust the pressure through the corresponding action; some pressure valves need to modify the pipeline, and the disassembly and assembly of the pipeline will affect the cleanliness of the entire hydraulic system of the commissioning product
