Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
Referring to fig. 1, an embodiment of the present invention provides a gas filter removal tool, including:
a wrench part 1, one end of which is provided with an opening 11 for clamping a bolt or a nut 4; and
and the connecting part 2 comprises a connecting rod 21 and a screw rod 22, one end of the connecting rod 21 is connected to the middle part of the wrench part 1, and the other end of the connecting rod is fixedly connected with the screw rod 22.
Based on the gas filter disassembling tool with the structure, when the sealing cover 6 of the gas filter is disassembled, on one hand, the sealing cover can be disassembled by matching the bolt of the sealing cover 6 through the opening 11 at one end of the spanner part 1, and on the other hand, the sealing cover can be vertically lifted and disassembled from the flange 5 by a maintainer holding the two ends of the spanner part 1 through screwing the screw rod 22 into the threaded hole 8 arranged in the middle of the sealing cover 6, so that the sealing ring at the periphery of the sealing cover 6 is prevented from deforming; so, the dismantlement of the sealed lid 6 of filter of two kinds of different grade types can be realized to this application, and it is more convenient to use, reduces the instrument quantity that the maintainer carried in the maintenance process, reduces maintainer's intensity of labour.
Preferably, one end of the connecting rod 21 is rotatably connected with the wrench part 1, and the rotating axis of the connecting rod 21 is perpendicular to the length direction of the wrench part 1, so that the connecting rod 21 and the wrench part 1 can be folded when not in use, and the carrying is convenient.
