Above-mentioned flowline and main body and handle and main body are plunger matching parts, one end of flowline and handle is stretches out outside main body, connect siphunculus and the engagement of handle gear, during rotating handles, can, under the drive of meshing gear, interface channel be rotated like this, when the first vacancy section has been gone to intersect with the second hollow out, oil can remove to flow into flowline through the hollow out of intersecting, and then completes sampling, and flow during sampling can intersect the size of area by the first vacancy section and the second hollow out completely to be adjusted; When the first vacancy section does not intersect with the second vacancy section, the first seal area and the second seal area have formed complete seal pad, have stoped oil to flow to flowline, complete sampling.During use, above-mentioned connection siphunculus can be communicated with the conservator of transformer.
Said apparatus is simple in structure, easy to operate, easy to control.
The area of the second seal area is greater than the area of the first vacancy section, in the time of further guaranteeing not sample like this, and the impermeability of device.
Main body is cylindric.Like this can conserve space, guarantee completing smoothly of sampling simultaneously.
Connect siphunculus along the axial setting of main body, flowline one end be connected the bottom surface that siphunculus docks, the other end stretches out main body one end; Handle one end and the side that is connected siphunculus gear engagement, the other end and stretches out main body.So both conserve space, can guarantee again the convenience of use and the accuracy of control.
The concept reference circle cylinder bottom surface of the bottom surface of aforementioned body and side and the concept of side.
The first end cap is circular, and wherein half is the first seal area, and second half is the first vacancy section, and the second end cap is circular, and the area of the second seal area is greater than the area of the first vacancy section.Can guarantee like this leakproofness of sampling and the accuracy of flow control.
Flowline is concentric setting with being connected siphunculus, and the area of the second seal area is greater than the area of the second vacancy section.Can further guarantee like this leakproofness of sampling and the accuracy of flow control.
Above-mentioned flowline be connected siphunculus and be cylindrical pipe, preferably, the internal diameter of flowline is not more than the internal diameter that connects siphunculus.
The first end cap and the second end cap are all preferably circle, and the diameter of the first end cap is not less than the internal diameter of flowline, and the diameter of the second end cap is not less than the internal diameter that connects siphunculus, the first end cap and the second end cap can be respectively by flowline be connected siphunculus and block; First end covers, and preferably, wherein a semicircle is the first seal area, and another semicircle is the first vacancy section; On the second end cap, preferably, being greater than 1/2 circle is the second seal area, and residue is the second vacancy section.
The NM technology of the utility model is prior art.
The utility model is good for the fan-shaped sample valve obturation effect of corner of electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer, good reliability, be not easy to occur seepage, capable of regulating flow quantity is easy and simple to handle, safety, is suitable for electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer in electric system and extensively installs and uses.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the fan-shaped sample valve structural representation of corner of electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer.
In figure, 1 is flowline, and 2 is the first seal area, and 3 is the first vacancy section, and 4 is the second seal area, and 5 is the second vacancy section, and 6 for connecting siphunculus, and 7 is corner gear, and 8 is handle, and 9 is main body.
