Abstract
The present invention relates to a kind of power station high pressure turbine by valve base lapping device, including handle, head rod, the second connecting rod and grinding carcass, described head rod one end and second connecting rod one end is connected with handle respectively, and the described head rod other end and the second connecting rod other end are connected with grinding carcass respectively.Compared with prior art, the present invention solves the problems, such as that high pressure turbine by valve body is repaired, while having the advantages that saving cost of overhaul use, raising operating efficiency, processing and fabricating cost are low, easy to operate.
Description
Technical field
The present invention relates to a kind of power station valve maintenance tool, more particularly, to a kind of power station high pressure turbine by valve base
Lapping device.
Background technology
At present, most of power station high pressure bypass valves are caused due to the aspect such as long-play or executing agency
Valve seat location is washed away, and the valve element and valve base sealing for washing away rear high pressure bypass valve do not cause leakage in high pressure bypass valve sternly, high
The steam of quality is directly discharged into condenser, influences unit efficiency.High pressure turbine by valve base is generally welded with jet chimney
It is connected, if sending high pressure turbine by valve base outside producer overhaul, it is necessary to cut high temperature and high pressure steam pipeline during maintenance,
Also need to weld, be heat-treated and detect a flaw after reparation, its workload very big and high cost.Valve is carried out in Overhaul site
The grinding reparation of seat is time saving, laborsaving can also to save expense, but the on-site grinding needs of high pressure turbine by valve base are a set of specially
The instrument of door.
The content of the invention
The purpose of the present invention is exactly that a kind of saving cost of overhaul is provided for the defect for overcoming above-mentioned prior art to exist
With, improve low, the easy to operate power station high pressure turbine by valve base of operating efficiency, processing and fabricating cost and grind dress
Put.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of power station high pressure turbine by valve base lapping device, it is characterised in that including handle, head rod,
Two connecting rods and grinding carcass, described head rod one end and second connecting rod one end are connected with handle respectively,
The described head rod other end and the second connecting rod other end are connected with grinding carcass respectively.
Described handle is provided with two and is respectively used to the through hole that head rod and the second connecting rod are passed through.
Also include that fastening nut, described head rod and the second connecting rod are consolidated after passing through through hole by fastening nut
It is fixed.
Described head rod and the second connecting rod is connected with grinding carcass respectively by silk tooth mode.
Described grinding carcass is circular configuration, and it is raised that its circumference is provided with bound edge.
Described grinding carcass is provided with two screwed holes being connected with head rod and the second connecting rod respectively.
The home position of described grinding carcass is provided with manhole.
Described grinding carcass is made a living the part that iron is made.
Described connecting rod is the part that #20 steel is made.
Described handle elects a diameter of φ 25mm, the carbon steel pipe of 180mm long as.
Compared with prior art, the present invention has advantages below：
1) cost of overhaul is saved to use：High pressure turbine by valve base need not cut and return factory's maintenance, and people has been saved in grinding on the spot
Expenses of labour and high price for repairing.
2) operating efficiency is improved：Using the present invention, grinding simplifies job step compared to factory's maintenance is returned on the spot, reduces
The workload of personnel.
3) processing and fabricating cost is low：Material requested of the present invention is cheap, and it is simple to make processing technology, and can be with
Reuse.
4) it is easy to operate：Simple structure of the present invention, small volume, it is lightweight, can quickly install and use,
It is easy to carry.
Brief description of the drawings
Fig. 1 is sectional view of the invention.
