Abstract
The utility model relates to a sealing device used for leak testing operation of transformer oil tank. According to the prior art, a heat radiator orifice on the transformer is blocked through a pure artificial operation mode, therefore the following defects exist: troublesome operation, lower operation efficiency, inferior sealing performance and easily caused inaccurate test result. The sealing device used for leak testing operation of transformer oil tank according to the utility model is characterized in that the sealing device comprises a clamper; the middle part of the clamper is provided with a liftable cover plate; and the lower end of the cover plate is bonded with a sealing gasket. The sealing device used for leak testing operation has the following advantages: reduced labor intensity of worker, increased operation efficiency, good sealing performance, and ensured accurate test result.
Description
Technical field
The utility model belongs to the accessory that carries out the impermeability detection in the transformer production process, is specifically related to a kind of packoff that is used for leak test operation of transformer tank.
Background technology
In the manufacture process of oil tank of transformer, in order to check the sealing of welding weld seam on the oil tank of transformer that finishes, the impermeability that need carry out fuel tank detects.Common way is to utilize cover plate, glue rope, rubber cushion etc. that each heating radiator mouth of pipe on the oil tank of transformer is sealed, only keep an inflation inlet connect tensimeter fill the compression air detect.But because the heating radiator mouth of pipe of same specification is more on the fuel tank, seal with said method, troublesome poeration, work efficiency is lower, and this in addition pure manual mode of operation carries out shutoff to heating radiator, and sealing is not good, causes test result inaccurate easily.
Summary of the invention
The purpose of this utility model provides a kind of packoff that is used for leak test operation of transformer tank, effectively increases work efficiency, and sealing is good, and test result is accurate.
For this reason, the utility model is taked following technical scheme: a kind of packoff that is used for leak test operation of transformer tank, it is characterized in that comprising anchor clamps, and the middle part of described anchor clamps is provided with a liftable cover plate, the lower end of the described cover plate pad that is bonded and sealed.Utilize the firm clip of anchor clamps to live heating radiator mouth of pipe lower edge on the oil tank of transformer, the cover plate that descends again fits tightly itself and the mouth of pipe, and is easy and simple to handle, and good seal performance is applicable to that the heating radiator mouth of pipe of same specification on the fuel tank seals.
Described anchor clamps are
Shape, the bottom of its two vertical part symmetrical fixture block that extends internally out, two symmetrical fixture blocks can be lived the firm fixing in the lower edge of the heating radiator mouth of pipe.
The middle part of described anchor clamps has screw, wears a screw mandrel in the screw, and the bottom of screw mandrel connects cover plate.Screw mandrel is rotated, can drive cover plate and carry out the height lifting, guarantee to carry out fitted seal with the heating radiator mouth of pipe of differing heights.
Described sealing gasket is a seal gasket.
The beneficial effect that the utility model has is embodied in: changed traditional troublesome operation line up that manually carries out and sealed, the specific purpose tool line up that design makes new advances seals, and has reduced working strength of workers, increases work efficiency, good seal performance guarantees that test result is accurate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. the anchor clamps 2. cover plates 3. screw mandrels 4. sealing gaskets 5. fixture blocks 6. heating radiator mouths of pipe.
Embodiment
Below in conjunction with specification drawings and specific embodiments substantive distinguishing features of the present utility model is further described.
Embodiment 1: as shown in Figure 1, a kind of packoff that is used for leak test operation of transformer tank comprises one
The integrated metal fixture 1 of shape, the bottom of vertical part, the anchor clamps 1 both sides symmetrical fixture block 5 that extends internally out.The middle part of anchor clamps 1 has screw, wears a screw mandrel 3 in the screw, and the bottom of screw mandrel 3 connects cover plate 2, and the lower end of cover plate 2 is with the seccotine rubber cushion 4 that is bonded and sealed, and screw mandrel 3 is rotated and can drives cover plate 2 liftings.
When carrying out leak test operation, at first anchor clamps 1 are nested with on the heating radiator mouth of pipe 6, utilize two fixture blocks, the 5 firm clips of anchor clamps 1 bottom to live the lower edge of the mouth of pipe, rotary screw rod 3 decline cover plates 2 afterwards, itself and the mouth of pipe are fitted tightly, a plurality of heating radiator mouths of pipe 6 on the transformer are all used this packoff sealing, only keep an inflation inlet at last and connect tensimeter and fill the compression air and detect.Reduced working strength of workers, increased work efficiency, good seal performance, test result is accurate.
