Abstract
The utility model relates to a simple oil sample valve for an oil-immersed distributing transformer. The utility model is arranged on a closing plate of an oil drain valve of an oil-immersed distributing transformer. The utility model comprises a valve seat, a screw bolt plug and an annular sealing gasket, wherein, the inner part of the valve seat is provided with a shaft hole, wherein, the front part of which is provided with a wide hole, and the back part of which is provided with a narrow hole. The shaft hole forms a staircase shape. An inner screw thread is arranged on the wall surface of the wide hole. An inclined hole is arranged on the lower wall surface at the depth of the wide hole. The end part of the screw bolt plug is provided with a neck shaft, and an outer screw thread is arranged on a screw post of the screw bolt plug. The annular sealing gasket is sheathed on the neck shaft of the screw bolt plug. Because the oil drain valve is closed in normal times, oil pressure in a transformer box can not act on the oil sample valve, and therefore, oil can not leak. When an oil sample is taken, an oil flow is injected into an oil sample bottle from the inclined hole at the lower part of the oil sample valve, which effectively controls the phenomenon that oil overflows. The utility model leads the oil drain valve to have the functions of the oil sample valve, a special oil sample valve on the transformer is cancelled, points of oil leakage are reduced, work hours and material consumption are reduced, and operation for taking an oil sample is simple and convenient.
Description
Technical field
The utility model relates to oil-immersed distributing transformer, relates in particular to the simple and easy oil sample valve that is used for oil-immersed distributing transformer.
Background technology
Oil-immersed distributing transformer will take oil sample termly in running, detect the performance of transformer oil, so the fuel tank bottom of oil-immersed distributing transformer also is equipped with oil sample valve except fuel outlet valve is housed, and this oil sample valve and oil tank of transformer communicate.Because processing and installation, oil sample valve often may become a leakage of oil point of transformer.For this reason, manufacturer has saved oil sample valve usually, directly draws oil sample from fuel outlet valve.
But the oil of fuel outlet valve flows not only slightly but also suddenly, and towards horizontal direction.When piling one bottle of oil sample in the oil sample bottle, oil spill completely, thereby cause environmental pollution, brought inconvenience to the user.
The utility model content
The purpose of this utility model is to provide a kind of simple and easy oil sample valve, and it can avoid the generation of leakage of oil point, can make the operation of drawing oil sample easier again.
A kind of simple and easy oil sample valve that is used for oil-immersed distributing transformer provided by the utility model is characterized in that: it is installed on the shrouding of fuel outlet valve of oil-immersed distributing transformer, comprises valve base, bolt plug and Gask-O-Seal; Wherein: being provided with a front portion in described valve base is step-like axis hole of being of narrow hole for wide hole, rear portion, and is provided with internal thread on the wall in described wide hole, and is provided with an inclined hole on the lower wall surface at wide hole depth place; Be provided with a neck axle that matches with the narrow hole of described valve base in the end of described bolt plug, and the double-screw bolt of described bolt plug is provided with the external screw thread that matches with the internal thread in the wide hole of valve base; Described Gask-O-Seal is enclosed within on the neck axle of described bolt plug.
The above-mentioned simple and easy oil sample valve that is used for oil-immersed distributing transformer, wherein, the end of the neck axle of bolt plug is provided with the step that extends out.
Adopted above-mentioned technical solution, the small-sized oil sample valve that promptly is welded on the shrouding of fuel outlet valve makes fuel outlet valve have the function of oil sample valve concurrently.Because fuel outlet valve cuts out at ordinary times, oil sample valve is not subjected to the effect of oil pressure in the transformer tank, has therefore avoided the worry of leakage of oil.And when drawing oil sample, open oil discharging valve, and unscrewing the bolt plug, oil stream i.e. inclined hole below oil sample valve injects the oil sample bottle, screws the bolt plug again by closing fuel outlet valve earlier after sampling finishes, and has effectively controlled the oil spill phenomenon.The utility model makes fuel outlet valve have the function of oil sample valve concurrently, has saved special-purpose oil sample valve on transformer, reduces the leakage of oil point, reduce work hours and material consumption, and it is easy and simple to handle to draw oil sample.
Description of drawings
Fig. 1 is that the utility model is installed in the structural representation on the fuel outlet valve of oil-immersed distributing transformer;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the simple and easy oil sample valve 1 of the utility model is installed on the shrouding 21 of fuel outlet valve 2, and fuel outlet valve 2 is connected on the oil tank wall 3 of oil-immersed distributing transformer.
As shown in Figure 2, the simple and easy oil sample valve 1 bolt plug 11 and the valve base 12 that comprise Gask-O-Seal 13, be processed into by steel.
In valve base 12, is provided with one and is step-like axis hole, and its front portion is wide hole 121 that the rear portion is narrow hole 122.On the wall in this wide hole 121, be provided with internal thread, and on the lower wall surface of 121 depths, wide hole, be provided with an inclined hole 123.
The end of bolt plug 11 is the neck axle 111 that is provided with step 113, and it matches with the narrow hole 122 of valve base, and Gask-O-Seal 13 is placed at neck axle 111 places.The double-screw bolt 112 of bolt plug 11 is provided with the external screw thread that matches with the internal thread in the wide hole 121 of valve base.
After the boring, valve base 12 is imbedded on shrouding 21 on the shrouding 21 of fuel outlet valve, make inclined hole 123 downward, all around with the electric welding welding, pore must not be arranged then.
The bolt plug 11 that Gask-O-Seal 13 is housed is tightened on the valve base 12 reaches sealing effectiveness, again shrouding 21 is encapsulated on the fuel outlet valve 2.
Open fuel outlet valve 2 when drawing oil sample, unscrew bolt plug 11, oil stream promptly flows out through inclined hole 123 places of valve base 12 bottoms and injects the oil sample bottle.Sampling should be closed fuel outlet valve 2 earlier when finishing, and treats in the inclined hole 123 that oil droplet is intact, wipes to screw bolt plug 11 again after doing and promptly finish.
