The technical scheme of the utility model is that: the utility model provides a visual oil change-over valve of getting for on oil-filled electrical equipment, it includes the valve body, case and handle, the valve body seals the other end for one end and is open cylindric structure, there is the cavity in the middle of the valve body, be equipped with connecting thread on the inside wall of valve body, be equipped with the through-hole in the middle of the blind end of valve body, be equipped with two annular recesses of circle on the through-hole inside wall, the case passes in the through-hole, the handle has been cup jointed on the outside end of case, the medial extremity of case is equipped with the end cover, the cover has the spring on the case between end cover and the valve body inside wall, the end cover outside is equipped with and gets hexagonal end cap matched with in the oil-filled electrical equipment and take over.
The connecting thread is matched with the external thread on the oil taking connecting pipe of the oil-filled electrical equipment.
A sealing ring is arranged in the groove, and the sealing end of the valve body and the valve core are sealed through the sealing ring.
And a locking nut is arranged at the outer side end of the valve core, and the handle is fixed on the valve core through the locking nut.
The oil inlet and the oil outlet are communicated through an oil taking channel.
The valve body is made of transparent organic glass material.
The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, get oil through the change-over valve, can easily take out transformer oil from oil charge electrical equipment alone, thereby avoided behind the oil spout staff to need the safety risk of recovering the in-process with the shutoff screw under the very big condition of oil injection pressure, the factor of safety of getting oil in-process has been increased, still avoided recovering a large amount of splash of transformer oil in the shutoff screw in-process on equipment shell and staff, the safe handling coefficient of oil charge electrical equipment getting oil has been improved greatly, the life of equipment oil valve is got to the extension, the time of staff getting oil has been shortened greatly, the safety of workman has been ensured, fine result of use has been gained.
