Abstract
The utility model discloses a tool special for maintaining a valve sealing gasket of a transformer. The tool special for maintaining the valve sealing gasket of the transformer comprises a sleeve, wherein the outer diameter of the sleeve is matched with that of a valve gland, and the inner diameter of the sleeve is slightly larger than the diameter of a valve rod of a valve; two teeth matched with a groove of the valve gland are symmetrically arranged at one end of the sleeve, a handle perpendicular to the axial direction of the sleeve is connected to the other end of the sleeve, and one end of the handle is provided with a cone. In the maintaining process, the teeth at one end of the sleeve are inserted into the gland groove, a gland can be disassembled and assembled by rotating the handle and does not need to be hit, and safety is improved; the gland is stressed evenly, the gland or the tool will not be damaged, the cone at one end of the handle is used for picking up a sealing ring more conveniently, threads of installing holes can not be damaged easily, difficulty in maintaining work is greatly reduced, and working efficiency is improved.
Description
Technical field
The utility model relates to service kit, is specifically related to a kind of transformer sealing gasket for valve special tool for examination and repair.
Background technology
Transformer is to utilize electromagnetic induction principle to change the device of alternating voltage, transformer can produce heat in running, can affect efficiency and the service life of transformer, especially high-tension transformer, must configure cooling system, with liquid state or gaseous medium, transformer is carried out to heat exchange, current most of transformer adopting from the mineral type insulating oil of the natural hydrocarbon mixture of petroleum refining as heat transferring medium, insulating oil is sealed in transformer shell, transformer shell is by pipeline communication fuel tank, pipeline is provided with valve, while being convenient to Repair of Transformer, discharge insulating oil, according to the diameter of the size of transformer and pipeline, the general spool that adopts carries out ball valve or the butterfly valve of 90 ° of rotary opening and closings along valve rod, the valve seat of valve is provided with installing hole, valve rod is rotationally connected with in installing hole, between valve rod and installing hole inwall, be filled with sealing gasket, the opening part of installing hole has been threaded connection gland, valve rod runs through gland, sealing gasket is generally made by rubber or graphite, easily wearing and tearing after valve repeatedly opens and closes, lose sealing effectiveness, must change in time in case insulating oil leaks, affect the use of transformer, there is no at present a kind of instrument that is specifically designed to maintenance sealing gasket, when maintenance sealing gasket, first with straight screwdriver oblique cutting, enter in symmetrically arranged two grooves on gland, by knocking screwdriver afterbody, make gland rotate gradually disengaging valve seat, with screwdriver tip, choose again the sealing gasket of wearing and tearing, pack new sealing gasket into, and then oppositely insert in groove with screwdriver, by knocking, make gland fastening, easily hinder hand when knocking screwdriver dismounting gland, there is potential safety hazard, screwdriver is knocked easy damage simultaneously, and the one-sided stressed also easily damage of gland, the tip of screwdriver is wider, the easy screw thread of damage installing hole also while choosing the sealing gasket of wearing and tearing with screwdriver, the difficulty of visible sealing gasket service work is large, and efficiency is also very low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of transformer sealing gasket for valve special tool for examination and repair, and conveniently dismounting valve gland, replacing sealing gasket, reduce service work difficulty, increases work efficiency, and improves security simultaneously.
The utility model is achieved through the following technical solutions:
Transformer sealing gasket for valve special tool for examination and repair, comprises sleeve pipe, and the external diameter of described sleeve pipe and valve gland external diameter match, and the internal diameter of described sleeve pipe is slightly larger than the diameter of valve rod; Described sleeve pipe one end is arranged with the tooth that two grooves with valve gland match, and the other end of described sleeve pipe is connected with quill to vertical handle, and one end of described handle is circular cone.
The other end of described handle is plane.
The utility model has the advantage of:
One, the tooth of sleeve pipe one end being inserted to gland groove, is dismantled and assembled gland by turning handle, does not need to knock, and improves security;
Two, gland is stressed evenly, can not damage gland or instrument, and it is more convenient with the circular cone of handle one end, to choose sealing ring, is not easy to damage the screw thread of installing hole, greatly reduces the difficulty of service work, increases work efficiency;
Three, the other end of handle is plane, when Xinmi City's packing is put into installing hole and occurred, is convenient to Xinmi City's packing to press smooth, and there will not be with the conical end of screwdriver tip or handle and presses the situation that sealing gasket causes sealing gasket breakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Transformer sealing gasket for valve special tool for examination and repair as shown in Figure 1, comprises sleeve pipe 1, and the external diameter of described sleeve pipe 1 and valve gland external diameter match, and the internal diameter of described sleeve pipe 1 is slightly larger than the diameter of valve rod; Described sleeve pipe 1 one end is arranged with the tooth 2 that two grooves with valve gland match, and the other end of described sleeve pipe 1 is connected with and the axial vertical handle 3 of sleeve pipe 1, and one end of described handle 3 is circular cone, and the other end is plane.
