Description
Technical field
The utility model belongs to the transformer technology field, especially relates to a kind of valve that draws oil sample that transformer is used that has.
Background technique
Be typically provided with transformer oil sample valve in the transformer bottom; Its structure is mostly for being provided with the sample tap of sampling hole; Be rotary with the pine tar plug screw of terminal band seal ring in the sample tap, pine tar plug screw is provided with stubborn head, and stubborn head is located at the outside of sample tap; Adjust with spanner etc. with convenient, outside whole sample cock, be provided with closed nut.During normal the use, pine tar plug screw-driving is because the seal action of the end seal circle of pine tar plug screw; Transformer oil can not flow out; In the time need chemically examining to the transformer oil of transformer body, screw off the closed nut on the transformer oil sample valve sampling hole, pine tar plug screw is slowly back-outed; Transformer oil will flow out to the sampling hole of sample tap, with the convenient sampling to transformer oil on the oil sample valve.Because the oil sample valve does not have anti-theft feature, transformer is provided with transformer oil sample valve, is engaged in stealthy activity for the obstinate lawless person of social upward only a few opportunity is provided.Antitheft is the method for lead sealing to transformer oil sample valve now, and this method can not realize the antitheft of transformer oil veritably.
The model utility content
The purpose of the utility model is the structure to existing transformer oil sample valve, and its transformer oil is stolen problem easily, and a kind of transformer oil sample valve with anti-theft feature of reliable performance is provided.
For realizing above-mentioned purpose, the utility model has adopted following technological scheme to be: a kind of transformer anti-theft oil sample valve comprises the oil outlet tube, seal ring and the pine tar plug screw that are provided with internal thread; It is characterized in that: end is provided with step in the oil outlet tube; Pine tar plug screw is provided with step, and the step place of pine tar plug screw is provided with above-mentioned seal ring, but in the pine tar plug screw precession oil outlet tube; After screwing; The seal ring of pine tar plug screw withstands on the step surface in the oil outlet tube, and pine tar plug screw is in oil outlet tube, and the front-end face of pine tar plug screw is provided with three apertures.The line of three apertures is generally equilateral triangle.
Under the situation of oil sample valve closing, because pine tar plug screw is positioned at oil outlet tube, if there is not special tool just to have no idea pine tar plug screw in oil outlet tube, to back-out.Usually its special tool comprise the pin that three apertures on the front-end face of band and pine tar plug screw are corresponding band instrument can pine tar plug screw and oil outlet tube be locked and back-out.Band inserts three apertures to three pins of instrument, and rotating band just can or screw out instrument pine tar plug screw and oil outlet tube locking.During use, screw in pine tar plug screw to instrument through band, after screwing, the seal ring of pine tar plug screw withstands on the step surface in the oil outlet tube, and sealing is accomplished.In the time will drawing oil sample, band inserts three apertures to three pins of instrument, and rotating band just can screw out instrument to pine tar plug screw, opens sealing, and the transformer oil of transformer body just can flow out from fuel-displaced tube wall mouth, realizes sampling.
During concrete the use, the screw thread place of pine tar plug screw is provided with and goes out oil groove longitudinally.Transformer oil during more convenient like this drawing oil sample can flow out.
During practical implementation, pine tar plug screw is provided with limited step, and the tube wall of oil outlet tube is provided with screw, and the screw on the tube wall is rotary with stop screw, and when pine tar plug screw is tightened in the oil outlet tube, stop screw is positioned at the front end of pine tar plug screw limited step.Because transformer oil is very big at the pressure at oil outlet tube place, if when drawing oil sample, it is too much that pine tar plug screw screws out oil outlet tube; The transformer oil pump capacity is very big, so, be provided with stop screw; It is too much to guarantee that pine tar plug screw can not screw out oil outlet tube; When getting the transformer oil sample with assurance, the transformer oil pump capacity is seldom conveniently taken a sample.
During practical implementation, be installed with the stopper of band rubber seal at the oil outlet tube front end.The stopper that the structure of usually above-mentioned stopper is used with the oiling of transformer oil conservater, oil meter breathe that stopper and the capsule chamber stopper of usefulness or the like structure is identical, and main effect is to guarantee that water can not get in the oil outlet tube, get rusty preventing.Adopt stopper, compare, significantly reduced cost with original closed nut.
Because the oil sample valve of this structure must just can be opened by the special-purpose anti-theft tool of adapted, has improved the theftproof performance of transformer oil widely.
The beneficial effect of the utility model is: the utility model is simple in structure, and is easy to process, safe and reliable, can prevent effectively that the lawless person from stealing transformer oil through the oil sample valve.
Description of drawings
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the utility model embodiment's the pine tar plug screw and the structural representation of seal ring combination.
Among the figure: 1, oil outlet tube 2, pine tar plug screw 3, stopper 11, step 21, hole 22, seal ring 23, go out oil groove 24, limited step 31, rubber seal.
Embodiment
Among Fig. 1 and Fig. 2, a kind of transformer anti-theft oil sample valve comprises the oil outlet tube 1, seal ring 22 and the pine tar plug screw 2 that are provided with internal thread; End is provided with step 11 in the oil outlet tube 1; Pine tar plug screw 2 is provided with step, and the step place of pine tar plug screw 2 is provided with above-mentioned seal ring 22, but in the pine tar plug screw 2 precession oil outlet tubes 1; After screwing; The seal ring 22 of pine tar plug screw 2 withstands on 11 on the step in the oil outlet tube 1, and pine tar plug screw 2 is in oil outlet tube 1, and the front-end face of pine tar plug screw 2 is provided with three apertures 21; The screw thread place of pine tar plug screw 2 is provided with and goes out oil groove 23 longitudinally; The tube wall of oil outlet tube 1 is provided with screw, and the screw on the tube wall 2 is rotary with stop screw 4, and when pine tar plug screw 2 was tightened in the oil outlet tube, stop screw 4 was positioned at the front end of the limited step 24 of pine tar plug screw 2; Be installed with the stopper 3 of band rubber seal 31 at oil outlet tube 1 front end.
