Description
Technical field
The technology belongs to cleaning plant field, and in particular to a kind of nuclear island electric gate valve stuffing-box cleaning device for inner wall.
Background technology
With the operation of unit, there is abrasion or aging phenomenon in the stuffing-box of part nuclear island electric gate valve, causes filler to be sent out
Raw leakage, corresponding stuffing-box inwall corrodes because being contacted with water, while valve is chronically in hot environment, action frequency
Rate is very low, and filler particles occur " viscous glutinous " phenomenon with stuffing-box inwall.
Valve is in back seal position, and valve cannot be removed or isolated from system, and the executing agency of valve and york piece cannot
Remove, but the gland stud and dished spring assembly of valve can be removed, and gland and gland can take out from stuffing-box
And york piece top is fixed on, the filler assembly in stuffing-box can all take out.
Due to the gap very little between stuffing-box and valve rod, conventional cleaning tool cannot be insinuated into, therefore need to design and make
Make specific purpose tool, polishing cleaning is carried out to stuffing-box inwall, to remove the corrosion on stuffing-box inwall and remaining filler.
The content of the invention
It is an object of the invention to：A kind of nuclear island electric gate valve stuffing-box cleaning device for inner wall is provided, electric gate valve is cleared up
Corrosion and remaining filler on stuffing-box inwall.
Technical scheme is as follows：A kind of nuclear island electric gate valve stuffing-box cleaning device for inner wall, including charging bottle opener,
Outer tube, flexible shaft component, wherein brush head assembly, charging bottle opener provide rotary power for brush head assembly；Flexible shaft component passes through overcoat
Pipe, one end is connected with charging bottle opener output shaft, and the other end is connected with brush head assembly；
The output shaft of charging bottle opener is connected by shaft coupling with flexible shaft component, flanged packing ring is passed through on flexible shaft component and is put down
Packing ring fixes spring, so that flexible shaft component is tensioned in outer tube；Shaft coupling is the internal pipe for being provided with hexagon groove, one
The output shaft of end insertion electric screw driver, the other end inserts outer six square toes of flexible shaft component；Charging bottle opener is by connecting swivel nut and turning
Joint is connected, and adapter is connected on outer tube；
Brush head assembly is fixed with flexible shaft component end, and wear ring separates outer tube with flexible shaft component end.
The charging bottle opener provides rotary power for brush head assembly, and its moment of torsion and rotating speed are adjustable.
The flexible shaft component passes through 90 degree of curved outer tubes.
The external threaded portion of the charging bottle opener is connected by connecting swivel nut with adapter, and adapter is welded on outer tube
On.
It is fixed in the internal thread for screwing into flexible shaft component end of the brush head assembly.
Remarkable result of the invention is：
1) charging bottle opener can communicate rotational motion to brush by flexible axle, using the brush of elongated rod-shape to narrow gap
In stuffing-box inwall cleared up；
2) in flexible axle being constrained in into 90 degree of bend pipe by outer tube, flexible axle is entered with outer tube contact site using copper backing
Row isolation, prevents heating；
3) flexible axle is tensioned by tensioning spring later in the incoming outer tube of flexible axle, flexible axle is shaken outside dynamic friction when preventing rotation
Internal surface of sleeve pipe.
