Abstract
The utility model discloses a pressure release valve which is used with oil-immersed or gas-insulated mutual inductors. The pressure release valve which comprises a flange bottom seat, an upper seat, and an outer cover is characterized in that the bottom seat is orderly sheathed with a membranous disc, a spring and a pressure regulating plate. When the inner part of a mutual inductor has fault, and the inner pressure of the mutual inductor rises to a release pressure, the pressure release valve can release pressure in direction instantly within 2 ms, and the oil spraying quantity is little; when the pressure drops to a closed value, the utility model automatically closes; upper and lower screw threads of the pressure regulating plate are regulated to release pressure, and thus the operation of the utility model is safe.
Description
The utility model relates to the auxiliary equipment of a kind of oil immersion or gas-insulated mutual inductor, particularly a kind of pressure relief valve.
At present, the pressure relief valve that supporting mutual inductor uses is the glass pressure relief valve, when mutual inductor breaks down, when its internal pressure sharply is elevated to release pressure, the glass plate of pressure relief valve bursts, and the transformer oil in the mutual inductor sprays everywhere to be let out and use up, and transportation, installation are very inconvenient.
The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of orientable oil spout is provided, and fuel injection quantity is few, and pressure can be closed release pressure can regulate, safe and reliable pressure relief valve after descending automatically.
The purpose of this utility model is achieved in that pressure relief valve comprises flange base, the seat of honour, and outer cover is characterized in that being set with successively above the base membranous disc, spring, regulator board.
Fig. 1 is the utility model structural representation.
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
There was the flange base 1 of annular nib at the middle part above pressure relief valve comprised, the seat of honour 2, connect by screw rod 3 between two, base 1 bottom surface is embedded with seal ring 4, outer cover 5 middle part sides have directed jet 6, there is standing screw 7 at the inner top surface center, base 1 top chimb outer circumferential face and the vertical side cutting ferrule in membranous disc 8 bottoms, between be embedded with seal ring 9, membranous disc 8 bottom sides have oil through, middle part chimb outer circumferential face cutting ferrule spring 10 above the membranous disc 8, regulator board 11 is arranged above the spring 10, have oil through on the regulator board 11, the center has tapping hole, be threaded with the screw rod 7 of outer cover 5 end faces, the vertical side in bottom is threaded with the seat of honour 2 vertical side inner faces.
During supporting use, the base 1 of this pressure relief valve is discharged flange plate with the pressure of mutual inductor be connected, screwing outer cover 5 can use.When breaking down in mutual inductor inside, when its internal pressure is increased to release pressure, this valve can be in 2ms moment directed release, fuel injection quantity is few, closes automatically when pressure drops to close value, and is by regulator board 11 upper and lower threaded adjusting release pressures, safe and reliable to operation.
