Abstract
The utility model relates to a transformer oil tank valve which comprises a valve body connected to an oil in/out pipe of a transformer oil tank, the valve body and the oil in/out pipe are welded to form an integrated structure, and a reinforcing rib is arranged at the joint of the valve body and the oil in/out pipe. The transformer oil tank valve has the advantages that sealing processing at the joint of the valve body and the pipe is omitted, sealing performance of the transformer oil tank is better, and the oil leakage phenomenon is reduced; the sealing structure of a butterfly valve can bear large pressure to avoid leakage.
Description
Technical field
The utility model relates to a kind of oil tank of transformer valve.
Background technique
Oil tank of transformer leakage of oil problem is the comparison distinct issues that Transformer exists always, in oil tank of transformer leakage of oil, having sizable ratio is the seepage of turnover fuel tap door, the normal pipe of the mouth of pipe of turnover oil pipe is provided with pipe coupling flange, by flange, be connected with valve, the conventional sealing gasket sealing in joint, sealing gasket that the quality of sealing gasket, installation question and long-time running cause is aging etc., and reasons all can cause oil tank of transformer leakage of oil.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of oil tank of transformer valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of oil tank of transformer valve, the valve that comprises the turnover oil pipe that is connected in oil tank of transformer, valve is welded as overall structure with turnover oil pipe, and valve is provided with stiffening rib with the joint of turnover oil pipe.
Further, valve is butterfly valve.
Further, the valve plate of valve has oil resistant rubber, oil resistant rubber and valve cavity interference fit from the outside mold pressing of valve skeleton.
The beneficial effects of the utility model are: reduced the encapsulation process of valve and pipeline junction, the better tightness of oil tank of transformer, reduces oil leakage phenomenon and occur; Butterfly valve sealing configuration, can bear larger pressure non-leakage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. pass in and out oil pipe, 2. valve.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of oil tank of transformer valve as shown in Figure 1, comprises the valve 2 of the turnover oil pipe 1 that is connected in oil tank of transformer, and valve 2 is welded as overall structure with turnover oil pipe 1, and valve 2 is provided with stiffening rib with the joint of turnover oil pipe 1.
Valve 2 is butterfly valve, and the valve plate of butterfly valve has oil resistant rubber from the outside mold pressing of its skeleton, and oil resistant rubber and butterfly valve inner chamber interference fit reach sealing.It is non-leakage that the sealing configuration of butterfly valve can bear 600～800kPa.
Butterfly valve bi-side limited location seal ring, seal ring keeps certain elasticity in valve body groove, can not be subject to ultraviolet irradiation, increases sealability, increases the service life.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
