Abstract
The utility model relates to a transformer valve which is capable of sampling and draining oil and particularly relates to a dual-purpose anti-theft transformer oil-drain valve. The oil-drain valve comprises a valve body and a valve spool, wherein an oil-drain hole with an inner thread is arranged inside the valve body, the wall of the valve body is provided with a sampling hole, a sealing ring is arranged at the tail end of the valve spool, steps are arranged at the tail end of the oil-drain hole inside the valve body, the valve spool can penetrate through the sampling hole in a rotating mode, the front end of the valve spool is provided with a cylindrical end head, and the outer ring of the end head is provided with a groove. Accordingly, a front end of an existing valve spool is modified, an existing hexangular screw cap is modified into the cylindrical end head with the groove, and the oil-drain valve is simple in structure, convenient to process, reliable, safe and capable of preventing lawbreakers from stealing transformer oil through oil-drain valves.
Description
Technical field
The utility model belongs to the transformer technology field, especially relates to a kind of valve that draws oil sample and drain the oil that transformer is used that has.
Background technique
Common large oil immersed formula transformer bottom is typically provided with the transformer oil discharging valve, has the two kinds of functions that draw oil sample and drain the oil.Its structure is made up of valve body, spool and sheath etc. mostly.The wall portion of valve body is provided with sampling hole; Valve body is provided with drain oil; The spool cylindrical is provided with in the drain oil of the valve body that screw thread is spun on, and the step that the end of spool is provided with in the drain oil of seal ring and valve body forms sealing configuration, and the spool front end is provided with hexagon nut; Sheath is spun on the cylindrical of valve body, adopts screw thread to fix between sheath and valve body.During use; Screw out earlier and unloads lower jacket, slowly screw out spool, spool and valve body blow-by with the hexagon nut of instruments such as spanner through the spool front end; Transformer oil will be lentamente the sampling hole that is provided with of wall portion through valve body slowly flow out, realize sampling to transformer oil; When needs are drained the oil, unload spool from whole back-out of the drain oil of valve body, transformer oil will flow out from the drain oil of valve body, realizes draining the oil.The dual-purpose fuel outlet valve of the transformer of this structure adopts conventional spanner just can operate, and does not have anti-theft feature, is engaged in stealthy activity for the obstinate lawless person of social upward only a few opportunity
is provided.
The model utility content
The purpose of the utility model is the structure to existing transformer fuel outlet valve, and its transformer oil is stolen problem easily, and a kind of transformer fuel outlet 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: transformer two-purpose theft fuel outlet valve comprises valve body and spool; Be provided with tapped drain oil in the valve body, the wall portion of valve body is provided with sampling hole, and the end of spool is provided with seal ring; Drain oil end in the valve body is provided with step; But in the spool precession sampling hole, after screwing, the seal ring of the end of spool withstands on the drain oil end and is provided with on the step surface; It is characterized in that: the spool front end is the cylindrical body termination, and the cylindrical of termination is provided with groove.The transformer fuel outlet valve of this structure, instruments such as employing common wrench can not be realized drawing oil sample and draining the oil, and when needs draw oil sample or drain the oil, adopt special tool to realize.Usually its special tool is the sleeve that has outer-hexagonal, and the diameter of bore of sleeve is greater than the cylindrical body termination, and the wall portion of sleeve is provided with the tapped hole of band screw, and tapped hole is corresponding with the groove on the cylindrical of termination.Special-purpose sleeve is inserted in the termination, and screw screws in the tapped hole on the sleeve, and tip of screw withstands on the groove on the cylindrical of termination, and sleeve and termination are fixed, and spanner just can be back-outed through the outer-hexagonal of sleeve, realizes drawing oil sample or draining the oil.The utility model improves through the spool front end to existing technology, is provided with the cylindrical body termination of groove to original hexagon nut instead, has improved the theftproof performance of transformer oil widely.
During practical implementation, above-mentioned groove is three, is evenly distributed on the cylindrical of termination.
During practical implementation, the spool front end is provided with step surface, is provided with conical retaining edge between the termination of step surface and spool, and when the oil outlet of spool and valve body sealed, the step surface of spool front end was close on the end face of valve body.
During practical implementation, valve body is provided with outside thread, is provided with tapped sheath and is spun on the valve body.Sheath can prevent that spool and valve body from getting rusty, and plays a protective role.
The beneficial effect of the utility model is: the utility model improves through the spool front end to existing technology; Be provided with original hexagon nut the cylindrical body termination of groove instead; Simple in structure; Easy to process, safe and reliable, can prevent effectively that the lawless person from stealing transformer oil through oil discharging 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 a valve core structure schematic representation.
Among the figure: 1, valve body 2, spool 3, sheath 4, seal ring 11, sampling hole 12, sealed step 21, termination 22, retaining edge 23, groove.
Embodiment
Among Fig. 1 and Fig. 2, transformer two-purpose theft fuel outlet valve comprises valve body 1, spool 2 and sheath 3; Use tapped drain oil in the valve body 1, the wall portion of valve body 1 is provided with sampling hole 11, and the end of spool 2 is provided with seal ring 4; Drain oil end in the valve body 1 is provided with sealed step 12, but in the spool 2 precession sampling holes, after screwing; The seal ring 4 of the end of spool 2 withstands on the drain oil end and is provided with on 12 of the sealed step, and spool 2 front ends are cylindrical body termination 21, are provided with three grooves 23; Be evenly distributed on the cylindrical of termination 21, spool 2 front ends are provided with step surface, and 21 of the terminations of step surface and spool are provided with conical retaining along 22; When the oil outlet of spool 2 and valve body 1 sealed, the step surface of spool 2 front ends was close on the end face of valve body 1.Valve body 1 is provided with outside thread, is provided with tapped sheath 3 and is spun on the valve body 1.
