Abstract
The invention relates to an oil feeding and relieve valve of a high pressure electric appliance special device used for electrical equipment of power sector, which comprises a valve seat, a sealing ring I, an end face seal I, a sealing ring II, an inner shield clamp spring, an end face seal II, a valve plug, a sealing cap and a valve bonnet; the valve seat is thereon provided with the sealing ring I, an inner cavity of the valve seat is internally provided with the valve plug, the end face seal I is arranged between the end face of the valve plug and the valve seat, the sealing ring II is arranged on the outer diameter of the valve plug, the valve seat is thereon provided with the valve bonnet matching therewith, the end face seal II is arranged between the valve seat and the valve bonnet, and an oil outlet A is arranged on the valve seat; as the diameter of the oil outlet of the valve seat is less than the diameter of a solid filler of an insulating medium in an oil tank of a high pressure device connected therewith, the solid filler is prevented from flowing out; as a plurality of sealing rings are arranged, the sealing effect is good.
Description
Technical field
The present invention relates to a kind of device of using on the power industry electric equipment, be used to annotate the oil feeding and relieve valve of high pressure electric appliance special device of draining the oil on particularly a kind of high-tension apparatus.
Background technique
Relevant by retrieval patent documentation does not retrieve the oil feeding and relieve valve of high pressure electric appliance special device identical with structure of the present invention at present as yet.High-voltage electrical equipments such as existing high-voltage electrical equipment, particularly high-tension current inductor, voltage transformer and circuit breaker generally adopt insulating oil to insulate as medium.After High-Voltage Electrical Appliances carry out oiling to equipment, equipment will regularly change and drain the oil.Oil-filling and drainage valve on the existing high-voltage electrical equipment generally adopts the spool steel ball to combine with spring and carries out unilaterally connected owing to structural reason.Because the medium insulating oil is after using, particularly there is medium in the oil unavoidably, when medium during by the surface of contact between spool steel ball and the spool, often because the existence of impurity causes impurity to be trapped between spool steel ball and the spool, cause that sealing effect descends, thereby phenomenons such as oil impregnate occur leaking, affect the performance of product, so be necessary existing product is improved, to improve the quality of product, satisfy actual needs.
Summary of the invention
The objective of the invention is to provide a kind of, have good sealing effect, can adapt to a kind of oil feeding and relieve valve of high pressure electric appliance special device with solid filler user mode in the structural improvement of existing Oil-filling and drainage valve.
Technical characteristics of the present invention is: considering that adaptability is strong, be designed to comprise the oil feeding and relieve valve of high pressure electric appliance special device of valve seat, seal ring I, end face seal I, seal ring II, interior block card spring, end face seal II, spool, sealing cap, bonnet on the basis of good seal performance, on valve seat, be provided with seal ring I, in the inner chamber of valve seat, be provided with spool, between the end face of spool and valve seat, be provided with end face seal I, on the external diameter of spool, be provided with seal ring II, described spool is provided with radial direction oil hole, axial oilhole, and is provided with the zigzag fashion seal groove in the end of spool; Block card spring in the inner chamber of valve seat, being provided with, on valve seat, be provided with the bonnet that matches with it, be provided with end face seal II between valve seat and bonnet, be provided with oil outlet A on valve seat, its diameter of oil outlet A that described valve seat is provided with is less than the diameter of the solid filler in the fuel tank that is attached thereto.
During use, valve seat is installed or is welded on the high-voltage electrical equipment, and oil outlet is communicated with the oil circuit of high-voltage electrical equipment by connecting bolt; The end face of valve seat seals by seal ring I.When the needs oiling, unscrew the bonnet that is connected on the valve seat, sealing cap is thrown off, unscrew spool, spool axial end and end face seal I are unclamped, produce the end clearance, again external oil filler pipe is connected with the sawtooth pattern joint of spool, under the effect of ambient pressure, insulating oil injects by the axial oilhole of spool, and flows through the gap of spool and valve seat and enter in the high-voltage electrical equipment cavity by oil outlet by radial direction oil hole, reach the numerical value of regulation when oil filling amount, rotary spool makes spool push down end face seal I, thereby oil circuit is disconnected, again sealing cap is put, make its end face seal, screw bonnet, thereby form integral sealing.When needs are emitted insulating oil in the high-voltage electrical equipment, take bonnet apart, remove sealing cap, and unscrew spool, make the insulating oil in its high-voltage electrical equipment flow into radial clearance, radial direction oil hole, the axial oilhole of spool, and pass through sawtooth pattern connection port place outflow insulating oil by oil outlet.Diameter on the valve seat oil outlet its objective is to prevent what solid filler was provided with by the oil outlet outflow less than the diameter of the solid filler of the insulating medium on the high-tension apparatus that is attached thereto.
Advantage of the present invention is: because the diameter of the oil outlet of valve seat is less than the diameter of the solid filler of the insulating medium in the fuel tank on the high-tension apparatus that is attached thereto, thereby avoided the outflow of solid filler; Because be provided with a plurality of seal rings, and the mode that adopts axial seal to combine with radial seal, thereby make good sealing effect; Because rational in infrastructure, widely applicable, reliable performance, thus can be widely used in High-Voltage Electrical Appliances and other special device is annotated the control of draining the oil, so very big practical and popularizing value is arranged.
