Abstract
A valve oil pressure detection leakage testing device for a transformer relates to the field of valve leakage testing devices. The valve leakage test device is mainly designed for solving the problem that the quality of the valve cannot be guaranteed due to the fact that no oil pressure leakage test is carried out on the valve at present. It includes the oil tank, the oiling that the oil tank is connected, return oil pipe way, even there are lateral pipeline A and lateral pipeline B on the oiling, there is first fuel outlet valve on the lateral pipeline A, there is first fuel inlet valve on the lateral pipeline B, lateral pipeline A and lateral pipeline B's the other end all are linked together with the pipeline, there is the gear oil pump on the pipeline, lateral pipeline C and lateral pipeline D, there is the second fuel inlet valve on the lateral pipeline C, there is the second fuel outlet valve on the lateral pipeline D, lateral pipeline C's the other end is linked together with lateral pipeline D, lateral pipeline D's the other end is connected with the valve, be connected with the hose on the valve, manometer and bleed valve are equipped with on the hose, be connected with a plurality of test branch oil pipe on the. The advantage can realize that multiple valve detects jointly, guarantees the quality of valve.
Description
The technical field is as follows:
the utility model relates to a valve infiltration leakage test device field specifically is an oil pressure that detects transformer valve and use detects leakage test device.
Background art:
in order to ensure the quality of transformer products, leakage test detection is needed for transformer accessories entering a factory, such as ball valves, steel plate valves and vacuum butterfly valves, and the leakage test is carried out in a common air pressure or water pressure mode when the valve manufacturer leaves a factory without carrying out an oil pressure leakage test, so that the operability and the tightness of the selected valve opening and closing shaft heads cannot be checked, and the quality of the valves cannot be ensured.
The invention content is as follows:
the utility model aims to solve the technical problem that a transformer is with plate valve oil pressure detection leakage test device that can carry out oil pressure leakage test to the valve is provided.
The above object is achieved by: it comprises an oil tank, an oil inlet of the oil tank is connected with a vacuum oil filter through a pipeline, an oil outlet of the oil tank is connected with an oil injection pipeline and an oil return pipeline for injecting oil, be connected with lateral pipeline A and lateral pipeline B on returning oil pipe way, install first fuel outlet valve on the lateral pipeline A, be connected with first oiling valve on the lateral pipeline B, lateral pipeline A and lateral pipeline B's the other end all is linked together with the pipeline, install the gear oil pump on the pipeline, still be connected with lateral pipeline C and lateral pipeline D on the pipeline, install second oiling valve on the lateral pipeline C, install second fuel outlet valve on the lateral pipeline D, lateral pipeline C's the other end is linked together with lateral pipeline D, lateral pipeline D's the other end is connected with the valve, still be connected with the hose on the valve, install manometer and bleed valve on the hose, still be connected with a plurality of test branch oil pipe on the hose, during the test, will be connected in test branch oil pipe's outer end by the test valve.
The test method comprises the following steps: the gear oil pump is a one-way motor, when oil is filled, the two oil discharge valves are closed, the two oil filling valves are opened, the power supply of the gear oil pump is started, the valves are opened, and slow pressurization is started. During pressurization, the condition of the pointer of the pressure gauge and the condition of each valve need to be carefully observed. And slowly opening the air release plug, closing the air release valve after stable oil outlet, closing the valve when the pressure value is increased to 0.4Mpa, stopping the gear oil pump, and starting a leakage test.
And after the leakage test is finished, starting the gear oil pump to start oil return, closing the two oil injection valves, opening the two oil discharge valves, continuing for 5 seconds after the pointer of the pressure gauge returns to zero, closing the valves and the power supply of the gear oil pump, and opening the exhaust valve to release pressure.
The one-way oil pump can realize two processes of oil injection and oil drainage by closing the valve without replacing a pipeline.
The utility model has the advantages that: the device has simple operation flow and low cost, can realize the common detection of various valves (ball valves, butterfly valves and the like), effectively examines and selects the operability and the sealing property of the opening and closing shaft heads of the valves and ensures the quality of the valves.
