Description
Technical field
The utility model relates to electric system oil immersion type mutual-inductor class oil sealed sampling device, and particularly a kind of oil immersion type mutual-inductor gets fuel tap.
Background technology
Mutual inductor is one of indispensable visual plant in electric system power transmission and distribution project, according to the difference of heat eliminating medium, is divided into oil immersion type mutual-inductor, dry type mutual inductor and sulfur hexafluoride (SF
6) gas is the gas-insulated transformer of major insulation.Oil immersion type mutual-inductor adopts oil-paper combination insulation, transformer oil is as insulating medium, need to carry out regular oil sample detection in equipment use process, the short form test of oil, water trace analysis, electrical test, oil dissolved gas stratographic analysis, as source book data.
Tradition is got fuel tap and is generally adopted singe screw connecting mode and equipment to be assembled together, and getting, easy generation in oily process is loosening, there is leakage of oil hidden danger; When valve body is connected with spool, excessively causes sealed ring deformation, damage because of stressed, reduce the reliability of hermetically-sealed construction, easily occur causing leaking oil condition.
Utility model content
The purpose of this utility model is the shortcoming for above-mentioned prior art, and provide a kind of sealing reliability higher, not easily there is seepage, and install and use oil immersion type mutual-inductor easily and get fuel tap.
The purpose of this utility model is realized by following technical scheme:
A kind of oil immersion type mutual-inductor gets fuel tap, comprises valve body and spool, unlike the prior art:
Valve body is provided with oil inlet passage, internal thread and round platform;
Spool is provided with external thread, gets oily passage and limited step;
The sealed internal chamber formed after the external thread of spool spins with valve body internal thread with get oily passage, oil inlet passage communicates, the joint portion of valve body oil inlet passage and inner chamber is provided with sealing gasket, when spool and valve body screw, sealing gasket cuts off inner chamber and oil inlet passage, and limited step holds out against valve body.
Also comprise bonnet, bonnet and valve body spin, and spool is positioned at bonnet.
Also comprise pressing plate, valve body is provided with round platform, and round platform is fastenedly connected by pressing plate bolt and set collar.
The described hydraulic fluid port of getting getting oily passage is provided with sealing cap.
By controlling the duty of the severity control spool end sealing pad that spool screws in, thus application valve body oil inlet passage and spool get the logical resistance of oily passage, play valve function.During sampling, oil sample enters by set collar, oil inlet passage the hydraulic fluid port of getting getting oily passage and flows out, be connected with outer sampler by connecing oil nozzle again, do not contact with air in the whole process that draws oil sample, ensure that the oil sample taken out is consistent with the inner oil sample of mutual inductor, carry out the major insulation situation of stratographic analysis energy actual response mutual inductor.When spool is tightened, the sealing gasket power that is squeezed cuts off oil inlet passage and inner chamber, and spool limited step is just spacing to sealing gasket, is unlikely to extrude sealing gasket transition.
Originally advantage or the beneficial effect of fuel tap is got:
1. change the structure of valve body and set collar, add pressing plate, by pressing plate more than one piece bolt clamp device, avoid loosening getting in oily process easily to produce;
2. spool adds limit sealing structure, slow down the wearing and tearing of O-ring seal, even if frequent operation also can not destroy sealing, drastically increases the sealing property of equipment.
Accompanying drawing explanation

Embodiment
Below in conjunction with drawings and Examples, the utility model content is further elaborated, but is not to restriction of the present utility model.
Embodiment:
With reference to Fig. 1-Fig. 3, a kind of oil immersion type mutual-inductor gets fuel tap, comprises valve body 3 and spool 2,
Valve body 3 is provided with oil inlet passage 3-2, internal thread 3-1 and round platform 3-3;
Spool 2 is provided with external thread 2-3, gets oily passage 2-4 and limited step 2-2;
The sealed internal chamber 12 formed after the external thread 2-3 of spool 2 spins with valve body 3 internal thread 3-1 with get oily passage 2-4, oil inlet passage 3-2 communicates, the joint portion of valve body oil inlet passage 3-2 and inner chamber 12 is provided with sealing gasket 9, when spool 2 and valve body 3 screw, sealing gasket 9 cuts off inner chamber 12 and oil inlet passage 3-2, and limited step 2-2 holds out against valve body 3.
Also comprise bonnet 1, bonnet 1 and valve body 3 spin, and spool 2 is positioned at bonnet 1, for the protection of spool 2.
