Abstract
The utility model discloses an oil drain valve structure for transformer accidents. The oil drain valve structure comprises a ball valve, wherein a valve opening at one end of the ball valve is communicated with an oil tank, a valve opening at the other end of the ball valve is communicated with a bend connection pipe, a flange disc is welded at one end of the bend connection pipe, a central through hole is formed in the middle of the flange disc, a metal cover plate is connected to the bottom face of the flange disc, and a glass sealing plate is arranged in the central through hole of the flange disc. The oil drain valve structure replaces a common butterfly valve structure in the process of oil drainage of transformer accidents, the problems that the common butterfly valve structure is not convenient to operate, affects cleanliness and leaks oil are solved, and the transformer accidental oil drain valve structure has the advantages of being good in sealing performance, convenient to operate, clean and friendly to the environment, and the like, and the oil flow direction in oil drainage is controlled.
Description
Technical field
The utility model relates to Accident of Transformer fuel outlet valve field, is specially a kind of Accident of Transformer fuel outlet valve structure.
Background technology
Accident of Transformer fuel outlet valve is the important component part of power transformer, is the important guarantee of transformer safe operation.Traditional accident fuel outlet valve structure is at a pipe joint of fuel tank bottom weldering, and then pipe joint is connected by bolt with butterfly valve.Because butterfly valve structure exists seal defect under large pressure, easily cause transformer oil leak, and transformer is having an accident need to drain the oil time, operating personnel need first all bolts are unclamped, and the time is longer; In the process of draining the oil, transformer oil is splash forward, and oily splash position is wayward, easily affects the environment of periphery.
Utility model content
The purpose of this utility model is to provide a kind of Accident of Transformer fuel outlet valve structure, the problem existing to solve prior art.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of Accident of Transformer fuel outlet valve structure, it is characterized in that: comprise ball valve, ball valve one end valve port is communicated to fuel tank, a pipe end of elbow union is installed and be communicated with to ball valve other end valve port, another pipe end of elbow union is welded with ring flange, in the middle of described ring flange, have the central through hole being communicated with another pipe end of elbow union, described ring flange bottom faces is connected with metal cover board, and in the central through hole of ring flange, is provided with the glass shrouding that is supported and covered another pipe end of elbow union by metal cover board.
Described a kind of Accident of Transformer fuel outlet valve structure, is characterized in that: between described glass cover-plate and ring flange, be respectively arranged with sealing ring between glass cover-plate and metal cover board.
The utility model good effect is as follows:
The utility model adopts ball valve and elbow union, and elbow union one end is connected with fuel tank by ball valve, other end welding flange, and ring flange bottom faces connection metal cover plate arranges glass shrouding between ring flange and metal cover board.This structure has ensured the sealing effectiveness of transformer, avoids oil seepage phenomena.Once transformer has an accident, need promptly drain the oil time, only need shattered glass shrouding, simple to operation, and oil flows to controlledly while draining the oil, avoids the pollution of oil to transformer surrounding enviroment, has improved product appearance quality.
Brief description of the drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model ball valve schematic diagram.
Fig. 3 is syndeton phantom between the utility model elbow union and ring flange, metal cover board.
Embodiment
As shown in Figure 1-Figure 3.A kind of Accident of Transformer fuel outlet valve structure, comprise ball valve 1, ball valve 1 one end valve port is communicated to fuel tank 6, a pipe end of elbow union 2 is installed and be communicated with to ball valve 1 other end valve port, another pipe end of elbow union 2 is welded with ring flange 7, in the middle of ring flange 7, have the central through hole being communicated with elbow union 2 another pipe ends, ring flange 7 bottom faces are connected with metal cover board 3, and in the central through hole of ring flange 7, are provided with the glass shrouding 4 that is supported and covered elbow union 2 another pipe ends by metal cover board 3.Between glass cover-plate 4 and ring flange 7, be respectively arranged with sealing ring 5 between glass cover-plate 4 and metal cover board 3.
Claims (2)
1. an Accident of Transformer fuel outlet valve structure, it is characterized in that: comprise ball valve, ball valve one end valve port is communicated to fuel tank, a pipe end of elbow union is installed and be communicated with to ball valve other end valve port, another pipe end of elbow union is welded with ring flange, in the middle of described ring flange, have the central through hole being communicated with another pipe end of elbow union, described ring flange bottom faces is connected with metal cover board, and in the central through hole of ring flange, is provided with the glass shrouding that is supported and covered another pipe end of elbow union by metal cover board.
