Abstract
A needle-shaped sampling valve of a charged oil sampling device for the oil immersed bushing of a transformer comprises a valve body and a valve core. The valve body and the valve core are plunger andbarrel assemblies. The valve core is provided with threads capable of matching with the inner threads of a passage on the valve body. A screw cap on the valve core is screwed on the outer threads ofthe passage of the valve body. A polytetrafluoroethylene seal ring is arranged on the connection part of the screw cap and the valve core. An oil inlet is arranged on the valve body at the other end corresponding to the passage. An oil outlet is radially arranged on the middle part of the valve body along the passage of the valve body, and the screw cap is screwed on the outer threads of the oil outlet. The bottom of the valve core is provided with a polytetrafluoroethylene plug in the shape of a tapered step, and the plug fits into a tapered hole on the bottom of the passage of the valve. Theutility model has the advantages of reliable seal performance, capability of quantitatively regulating oil flow and simple and safe operation. The needle-shaped sampling valve is suitable for the broad installation use of oil charge appliances and equipment of electric power systems.
Description
Technical field
The utility model relates to a kind of electric system electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer that is used for, and is specifically related to a kind of aciculiform sample valve that is used for electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer.
Background technology
At present, in the system of State Grid, make every effort to progressively realize main-transformer is implemented repair based on condition of component (condition diagnosing under the no cut-off condition and maintenance), yet, when oil-immersed sleeve pipe of transformer carries out charged drawing oil sample, but be subjected to some restrictions of sample valve, this is that valve is airtight, reliability is relatively poor because great majority draw oil sample, seepage takes place easily, and the inconvenience that draws oil sample, be not easy Control Flow.
The utility model content
The purpose of this utility model is at above-mentioned weak point, provides that a kind of obturation effect is good, good reliability, is difficult for taking place the aciculiform sample valve that is used for electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer of seepage, scalable flow.
In order to achieve the above object, the utility model has been taked following technical scheme: a kind of aciculiform sample valve that is used for electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer, comprise valve body and spool composition, its valve body and spool are plunger matching parts, spool is provided with screw thread and can matches with the internal thread of valve channel, the operator can realize getting the adjusting of oily flow by tuning spool, the external thread of valve channel spins with the nut of being located on the spool, nut and spool joint portion are provided with teflin ring, make that whole sample valve obturation effect is good, good reliability is difficult for taking place seepage; An other end relative with valve channel is provided with oil-in, and oil-in also is provided with screw thread and the O-ring seal that matches with pipe under fuel-displaced drawing; The valve body middle part radially is provided with one along valve channel and gets hydraulic fluid port, and the external thread of getting hydraulic fluid port spins mutually with bonnet, and the spool end is equipped with the teflon plug of tapered shape, and the teflon plug matches with the terminal bellmouth of described valve channel.
The beneficial effects of the utility model are: the sample valve obturation effect is good, good reliability, be difficult for taking place seepage, easy and simple to handle, the safety of scalable flow, adopt the plug and the O-ring seal oil resistant effect of teflon material and seal new better, longer service life is suitable for electric system and fills electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer and extensively install and use.
