Technical field
The utility model relates to a kind of gas flow regulating valve rod and valve head dismantling device.
Background technology
The gas flow control valve plays the effect of regulating gas flow in the coal gas modular system, control generation load in power plant.In the CCPP generating set, the coal gas that the corex stove is produced enters the combustion gas unit, generates electricity, and coal gas can be utilized once more, can directly not be discharged in the atmosphere, has played the effect of environmental protection.The whole generating unit is when when light oil switches to gas to generate electricity, and any one standard-sized sheet almost of two gas flow control valves passes through coal gas in the coal gas module; Another gas flow valve is then mainly controlled gas flow by its aperture, thus the control generated energy.The gas flow control valve is worked owing to being in the special environment; be subjected to the impact of gas flow and the corrosion of gas for a long time, the gas flow regulating valve rod ruptures easily, causes whole compressor emergency shutdown; equipment can't move, and surrounding environment and economic interests are all produced very big loss.The valve rod of gas flow control valve and valve head gap are less; pipe vice can't use; so in the process of whole disintegration maintenance, must dismantle valve rod and valve head, but use chain tongs that many defectives are arranged with chain tongs; can't protect equipment with chain tongs; the moment size can't be grasped, and valve rod and valve head are crossed pine or tension when dress is multiple, all make valve rod place discontinuity; fracture once more easily; shortened the service time of valve rod, increase the maintenance number of times, waste maintenance resource; compressor emergency shutdown is frequent; and use chain tongs dismounting gas flow control valve consuming time longer, waste time and energy, increased the cost of overhaul; overhaul efficiency is lower, influences whole unit and normally moves.
Summary of the invention
Technical problem to be solved in the utility model provides the dismantling device of a kind of gas flow regulating valve rod and valve head, conveniently detachable gas flow regulating valve rod of this instrument of utilization and valve head, realize gas flow control valve fast assembling-disassembling, in place, shorten the replacing time greatly, improve overhaul efficiency, reduced the cost of overhaul, improved maintainer's operating environment, reduce labour intensity, guaranteed the normally operation on time of whole unit.
For solving the problems of the technologies described above, the utility model gas flow regulating valve rod and valve head dismantling device comprise a valve rod wrench for dismounting and valve head wrench for dismounting, described valve rod wrench for dismounting comprises first handle, the first U-shaped spanner and torque spanner interface, described first handle one end connects the U-shaped bottom of the described first U-shaped spanner, described torque spanner interface is located at the connecting portion of the described first handle and the first U-shaped spanner, the U-shaped aperture pitch of the described first U-shaped spanner and the pitch match of stem groove, described torque spanner interface is the projection that a center has endoporus, the shape of described endoporus and the form fit of torque spanner, described valve head wrench for dismounting comprises the second handle and the second U-shaped spanner, described second handle one end connects the U-shaped bottom of the described second U-shaped spanner, the U-shaped aperture pitch of the described second U-shaped spanner and the pitch match of valve head groove.
According to the torque spanner shape of routine, the interior hole shape of above-mentioned torque spanner interface is interior four jiaos or interior hexagonal.
Because the utility model gas flow regulating valve rod and valve head dismantling device have adopted technique scheme, promptly make valve rod wrench for dismounting and valve head wrench for dismounting, valve rod wrench for dismounting and valve head wrench for dismounting are formed by handle and U-shaped spanner, the U-shaped aperture pitch of its U-shaped spanner is mated with the flute pitch of valve rod and valve head respectively, the valve rod wrench for dismounting also is provided with the torque spanner interface at the connecting portion of handle and U-shaped spanner, is used for the socket torque spanner and turns valve rod.Conveniently detachable gas flow regulating valve rod of this instrument and valve head, realize gas flow control valve fast assembling-disassembling, in place, shorten the replacing time greatly, improved overhaul efficiency, reduced the cost of overhaul, improve maintainer's operating environment, reduce labour intensity, guaranteed the normally operation on time of whole unit.
