The detection device comprises a feedback float, a leakage detection valve, a control circuit and an acousto-optic circuit, wherein the feedback float is arranged in the oil tank of the hydraulic system; the leakage detection valve comprises a solenoid valve, a stop valve and a valve-in hydraulic cylinder; the solenoid valve and the stop valve are respectively arranged at two sides of the valve-in hydraulic cylinder and are connected with the valve-in hydraulic cylinder; the valve-in hydraulic cylinder is connected with the control circuit; and the control circuit is connected with the acousto-optic circuit. Compared with the prior art, the oil leakage detecting device of the hydraulic system disclosed by the utility model has the advantages that 1) the device can quickly detect the leakage of an executive component of a hydraulic pipeline; 2) inner leakage of the hydraulic cylinder is detected; 3) a medium of the leaked pipeline is rapidly stopped; 4) the intensity and risk of manual check are reduced; and 5) the leakage loss of the hydraulic medium is reduced and the application is wide.
Description
Technical field
The utility model relates to the hydraulic system technical field, particularly a kind of hydraulic system Oil Leakage Detecting device.
Background technique
Hydraulic equipment is used widely in life, but causes the hydraulic equipment leakage of oil to have multiple reason to produce, and how judging, close the leakage of oil pipe valve at short notice is the key issue in the various manufacturing mechanisms.In case the intact termination of pumping of the hydraulic pressure oil leakage in the production in the hydraulic oil container is refueled and then needed the long period, production will be interrupted.Boats and ships, aircraft, metallurgical equipment, usually by an oil pump feed dozens of executive component, if any the leakage of oil of a point, judgement is got up very difficult, when leak source is difficult to accomplish corresponding inspection processing high temperature, high humidity, stenosis people.
Therefore, hydraulic system needs a kind of practical, reasonable in design, safe and reliable device in time to find the hydraulic leak problem.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic system Oil Leakage Detecting device; This device has effectively solved the problem that fast detecting goes out leakage of oil place in the hydraulic system and in time closes the leakage of oil pipeline; This device is simple and practical, reasonable in design, has saved the detection time of hydraulic system greatly.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of hydraulic system Oil Leakage Detecting device comprises feedback buoy, leak test valve, control circuit, acousto-optic circuit, and the feedback buoy is arranged in the fuel tank of hydraulic system; Leak test valve comprises oil hydraulic cylinder in the solenoid valve, stop valve, valve, solenoid valve and stop valve be arranged at respectively in the valve oil hydraulic cylinder both sides and with valve in oil hydraulic cylinder be connected; Oil hydraulic cylinder is connected with control circuit in the valve, and control circuit is connected with acousto-optic circuit.
Compared with prior art, the utility model has the advantages that: 1) this device can leak by fast detecting hydraulic pipe line executive component; 2) let out in the detection oil hydraulic cylinder; 3) fast leakage line is ended medium; 4) reduce hand inspection intensity and dangerous 5) reduce hydraulic medium leakage loss, use more extensive.
