Abstract
The utility model discloses a multifunctional oil valve of a main transformer oil pipe. The problem that due to structures, oil supplementing and oil sampling of an existing transformer on-load tap charger oil pipe oil valve, an existing main transformer oil conservator oil charging oil valve and an existing air discharging oil valve are difficult to conduct is mainly solved. The multifunctional oil valve is characterized in that a valve element (2) is connected in a valve body (1) through threads, the lower end of the valve element (2) is conical and is located on an inner bench hole of the valve body (1), a sealing cap (3) is connected to the upper end of the valve body (1) through threads, a blinded hole is formed in the valve element (2), oil holes are correspondingly formed in the two sides of the lower portion of the valve element (2), a sealing ring is arranged in the middle of the valve element (2), and a sealing ring is arranged on the upper end face of the valve body (1). The multifunctional oil valve of the main transformer oil pipe has the advantage that due to the structures, oil supplementing and oil sampling of a transformer on-load tap charger oil pipe oil valve, a main transformer oil conservator oil charging oil valve and an air discharging oil valve are convenient to conduct.
Description
Technical field
The utility model relates to throttle used on a kind of transformer, especially the multi-functional throttle of main transformer oil pipe.
Background technology
In power transmission and transformation field, on load tap changer oil fuel tube throttle, main transformer conservator repairing throttle, exhaust throttle on transformer.And existing on-load tap changers of transformers oil fuel tube throttle and main transformer conservator repairing throttle, exhaust throttle are because reasons in structure exists repairing and the difficult problem that draws oil sample, increase the operating time, also increase waste simultaneously and pollute.
Summary of the invention
In order to solve existing on-load tap changers of transformers oil fuel tube throttle and main transformer conservator repairing throttle, exhaust throttle because reasons in structure exists repairing and draws oil sample difficult problem.The utility model provides a kind of multi-functional throttle of main transformer oil pipe.The multi-functional throttle of this main transformer oil pipe has on-load tap changers of transformers oil fuel tube throttle and main transformer conservator repairing throttle, exhaust throttle because reasons in structure exists repairing and draws oil sample feature easily.
The technical solution of the utility model is: the multi-functional throttle of this main transformer oil pipe comprises valve body, spool and sealing cap.Spool is threaded connection in valve body, and spool lower end is conical, and is sitting on valve body inner step hole, sealing cap is threaded connection in valve body upper end, has blind hole in spool, and both sides, spool bottom are to there being oilhole, spool middle part is equipped with sealing ring, and valve body upper surface is equipped with sealing ring.
The utlity model has following beneficial effect: the multi-functional throttle of this main transformer oil pipe is owing to adopting spool to be threaded connection in valve body, spool lower end is conical, and be sitting on valve body inner step hole, sealing cap is threaded connection in valve body upper end, in spool, there is blind hole, both sides, spool bottom are to there being oilhole, spool middle part is equipped with sealing ring, valve body upper surface is equipped with ring structure, thereby facilitate on-load tap changers of transformers oil fuel tube throttle and main transformer conservator repairing throttle, exhaust throttle is because reasons in structure exists repairing and draws oil sample, and structure and simple to operate.The multi-functional throttle of this main transformer oil pipe has on-load tap changers of transformers oil fuel tube throttle and main transformer conservator repairing throttle, exhaust throttle because reasons in structure exists repairing and draws oil sample feature easily thus.
brief description of the drawings:
Accompanying drawing 1 is the utility model structural representation.
1-valve body in figure, 2-spool, 3-sealing cap.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, the multi-functional throttle of this main transformer oil pipe comprises valve body 1, spool 2 and sealing cap 3.Valve body 1 is tubulose, inside there is step hole, spool 2 lower ends are conical, and be sitting on valve body 1 inner step hole, spool 2 is threaded connection in valve body 1, and sealing cap 3 is threaded connection in valve body 1 upper end, in spool 2, there is blind hole, spool 2 both sides, bottom are to there being oilhole, and spool 2 middle parts are equipped with sealing ring, and valve body 1 upper surface is equipped with sealing ring.Solve the problem that main transformer on-load voltage regulating switch extracts transformer oil sampling difficulty and the repairing of main transformer conservator.
When actual use, when the multi-functional throttle of this main transformer oil pipe draws oil sample, first open the sealing cap 3 of multi-functional throttle, be rotated counterclockwise spool 2, transformer insulation oil will be discharged from the oilhole of spool 2.Complete the work of drawing oil sample.When repairing, first open the sealing cap 3 of multi-functional throttle, again repairing tube head is screwed into clockwise spool 2 in connect on turn buckle, when being screwed into a half, another mistake hour hands rotary spool 2 arrives second half, this is to start oiling, transformer insulation oil will, from the oilhole of spool flows into conservator, in the time that conservator is injected into rational position, start dextrorotation rotary plate 2 until close, unload counterclockwise again repairing tube head, complete repairing work.
