Wherein: 1, valve body; 2, go up interface; 3, lower interface; 4, left interface; 5, right interface.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, a kind of four-way of electrification oil sample acquisition device for oil-immersed sleeve pipe of transformer, four-way employing stainless steel material is processed on lathe and is made up of valve body and four interface structures, interface is located at valve body up and down, wherein go up interface and connect corrugated metal expander, lower interface connects a tube connector that is connected with sleeve pipe, and left interface is oil-filled interface and connects the additional check-valves of oil mass that right interface vacuumizes check-valves for vacuumizing interface and connecing one.The joint of described four-way adopts split-type structural, and wherein two interfaces connect sealing means and adopt the cutting ferrule sealing up and down, about two check valve seal adopt the oil resisting rubber jointings sealing.
This structure can keep the insulation property of inside pipe casing, and expander internal work pressure maintains 0.02MPa, and when the change in volume of inside pipe casing oil, the volume of expander changes thereupon, can reduce the oil mass that sleeve pipe causes because of drawing oil sample to compensate automatically.
It is No. 304 type of stainless steel processing of ASTM that operative norm is adopted in the design of cross valve, can vacuumize with oil-filled oil conservator by four-way, and require to test according to national JB/T9092-1999 " valve inspection and verification " and GB/T7747-1995 " check of needle valve and verification " rules, adhere to specification.
No. 304 type of stainless steel processing of ASTM are adopted in the design of through type screw rod, and require to test according to national JB/T9092-1999 " valve inspection and verification " and GB/T7747-1995 " check of needle valve and verification " rules, adhere to specification.This device connects good seal, and ne-leakage meets " DL-T572-95 power transformer operating standard " requirement.
