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, the stuffing-box of part nuclear island electric gate valve occurs wearing and tearing or aging phenomenon, 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 with stuffing-box inwall " viscous glutinous " phenomenon occurs for filler particles.
Valve is in back seal position, and valve can not be removed or isolated from system, and the executing agency of valve and york piece can not
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 be fixed on above york piece, 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 can not be insinuated into, therefore need to be designed and be made
Make specific purpose tool, polishing cleaning is carried out to stuffing-box inwall, to remove corrosion and the remaining filler on stuffing-box inwall.
Utility model content
The purpose of this utility model is：A kind of nuclear island electric gate valve stuffing-box cleaning device for inner wall is provided, cleared up electronic
Corrosion and remaining filler on stuffing box for gate valve inwall.
The technical solution of the utility model 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, brush head assembly, wherein charging bottle opener provides rotary power for brush head assembly；Flexible shaft component is passed through
Outer tube, 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, by flanged packing ring with putting down on flexible shaft component
Packing ring fixes spring, so that flexible shaft component is tensioned in outer tube；Shaft coupling is provided with the pipe of hexagon groove, one for inside
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 with 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 present utility model 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 the bend pipe that flexible axle is constrained in 90 degree 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, prevents that flexible axle is shaken outside dynamic friction during rotation
Internal surface of sleeve pipe.
