Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment mono-:
As shown in Figure 1, Figure 2 and Figure 3, bushing shell for transformer fuel outlet valve special tool for examination and repair, comprises handle 1, and one end of handle 1 is provided with adjustable wrench 2, and the upper surface of handle 1 other end is provided with four jiaos of adjustable spanners of size, and lower surface is provided with the adjustable circular sleeve of a size; Described four jiaos of spanners comprise four of upper and lower, left and right jaw block 3.
In four described jaw blocks 3, have at least two to be circular-arc.
On described jaw block 3, be respectively equipped with screwed hole, in described screwed hole, be provided with and adjust screw rod 4, adjust screw rod 4 and match with screwed hole.
The circular sleeve that described size is adjustable comprises the sleeve 5 that multilayer is nested with mutually, and the side wall inner surfaces of outermost layer sleeve is provided with equally distributed longitudinal fin, and the inner surface of inner layer sleeve sidewall and outer surface are equipped with equally distributed longitudinal fin; Outermost layer sleeve is fixedly connected on described handle 1, and inner layer sleeve is meshed by longitudinal fin respectively.
The position coordinating with described inner layer sleeve on described handle 1 is provided with holddown groove 6, and the bottom surface of inner layer sleeve is provided with the protruding block matching with holddown groove 6.
The side wall inner surfaces of sleeve 5 is provided with longitudinal fin can increase frictional force, easy to use; The connection that is arranged so that sleeve and handle of holddown groove 6 is more firm, uses more reliably, also can any one deck inner layer sleeve be installed by holddown groove 6.
When use, for the different bushing shell for transformer fuel outlet valve of common size, use adjustable wrench 2 to be adjusted to corresponding size and drain the oil; For tetragonal fuel outlet valve, rotation is adjusted screw rod 4 and it is advanced or retreat, and makes its clamping fuel outlet valve, can drain the oil; For columned fuel outlet valve, select to install suitable sleeve according to the diameter of fuel outlet valve, by the outer wall of the inwall clamping fuel outlet valve of sleeve, can drain the oil.
