Abstract
The invention relates to an anti-leakage energy-saving air release valve of a transformer, comprising a valve seat and an outer cover. An inner step hole is arranged at the inner end of the valve seat and is internally provided with a steel ball and a reset spring; an outer step hole is arranged at the outer end of the valve seat; the bottoms of the outer step hole and the inner step hole are communicated; the outer step hole is in threaded connection with a bolt thimble which comprises a bolt pillar at the outer end and a thimble at the inner end; the inner end of the thimble corresponds to the position of the steel ball; a vent hole nozzle communicated with the outer step hole/inner step hole is arranged on the lateral side of the valve seat; a sealing ring is arranged between the bolt pillar and the valve seat; the outer cover is in threaded connection with the inner end of the valve seat; and an external thread and an end surface sealing ring are arranged at the inner end of the valve seat. The invention has the advantages of simple and compact structure, practical function, convenient installation, no oil leakage for long-time operation and convenient oil recycling.
Description
Technical field
The present invention relates to a kind of anti-leakage energy-saving air release valve of transformer.
Background technique
The connecting tube and the radiator air relief cock seepage oil ratio of transformer are more now, and reason is that the air relief cock structure is not too reasonable, and air relief cock is made up of bolt column and seal washer, the bolt column repeated open, can damage seal washer, cause air relief cock seepage oil, long-term seepage oil influences the healthy operation of transformer.
In addition, because air relief cock and fixed wall thread gap are very little, venting work is difficult, and the transformer oil that overflows when exitting simultaneously can't reclaim, and also causes waste.
Summary of the invention
The object of the invention is to provide a kind of bleed valve of transformer anti-leakage energy-saving, and is easy for installation, and long-time running is oil-tight, is convenient to oil and reclaims.
To achieve these goals, the present invention adopts following technological scheme: anti-leakage energy-saving air release valve of transformer, comprise valve seat and outer cover, valve seat the inner is provided with interior step hole and steel ball and Returnning spring is set in the hole, the valve seat outer end is provided with outer step hole, outer step hole and interior step hole bottom are communicated with, outer step hole internal spiral is connected with the bolt thimble, the bolt thimble comprises the bolt column and the inner thimble of outer end, the inner of thimble is corresponding with the steel ball position, the outlet nozzle that the valve seat side is provided with outer step hole/interior step hole is communicated with.
Be provided with seal ring between described bolt column and the valve seat.
The inner bolt of described outer cover and valve seat.
Described valve seat the inner is provided with outside thread and end-face seal ring.
The present invention is simple in structure, function is practical, and compact structure, and is easy for installation, and long-time running is oil-tight, is convenient to oil and reclaims.
Description of drawings
Fig. 1 is a sectional structure schematic representation of the present invention.
Embodiment
Embodiment: as shown in Figure 1, anti-leakage energy-saving air release valve of transformer comprises valve seat 3 and outer cover 1, the inner bolt of outer cover 1 and valve seat 3.Valve seat 3 the inners are provided with interior step hole and steel ball 6 are set and Returnning spring 7 in the holes, valve seat 3 outer ends are provided with outer step hole, outer step hole and interior step hole bottom are communicated with, outer step hole internal spiral is connected with bolt thimble 2, bolt thimble 2 comprises the bolt column 10 and the inner thimble 5 of outer end, be provided with seal ring 9 between bolt column 10 and the valve seat 3, the inner of thimble 5 is corresponding with steel ball 6 positions, the outlet nozzle 4 that valve seat 3 sides are provided with outer step hole/interior step hole is communicated with.Valve seat 3 the inners are provided with outside thread and the end-face seal ring of fixing with outer wall 89.
During concrete enforcement, outer cover 1 is screwed connection with valve seat 3, and described valve seat 3 is screwed connection with outer wall 8, between be provided with seal washer 9.Be screwed connection between described bolt thimble 2 and the valve seat 3, described bolt thimble 2 is made up of bolt column 10 and thimble 5, and bolt column 10 is provided with seal ring 9.One end of steel ball 6 is provided with Returnning spring 7.Outlet nozzle 4 can connect the oil storage bottle.
When transformer need be exitted, take off outer cover 1 earlier, plastic tube one is terminated at outlet nozzle 4, the other end inserts in the oil storage bottle, the thimble 2 that slowly tights a bolt then, thimble 5 slowly backs down steel ball 6, and this moment, gas flowed out, because bolt column 10 is provided with seal ring 9, gas and oil can only flow out from outlet nozzle 4, wait for when having transformer oil to overflow, and gas emptying is described, at this moment the bolt thimble 2 of can slowly back-outing, after thimble 5 broke away from steel ball 6, steel ball 6 outlet in the effect lower seal of Returnning spring 7, takes off plastic tube then, load onto outer cover 1, the venting end-of-job.
