Abstract
The utility model relates to a slurry valve rod mechanism of an abrasive slurry valve, and aims to solve the problems that a provided valve should have the effect of simply removing internal scabs and have the characteristics of simple structure and convenience in operation. The technical scheme is that: the slurry valve rod mechanism with a disassembly-free repairable sealing surface comprises a valve shell, a cylindrical valve rod which is inserted in the middle of the shell and is matched with a valve rod nut for vertical movement, a valve clack which is arranged on the bottom of the valve rod and is used for closing the valve, a guide plate which is fixed in middle of the valve rod and is provided with an axial guide groove, and a guide rib which is matched with the guide groove so as to limit the rotation of the valve rod. The mechanism is characterized in that: a valve support is provided with a guide rib mounting hole, a shell plate for closing the hole is rotatablely hinged on the valve support, and the guide rib is arranged on one surface, which faces the valve rod, of the shell plate; and the top of the valve rod is also provided with a locking handle for locking the valve rod nut. The locking handle is matched with the valve rod through a thread structure.
Description
Technical field
The utility model relates to a kind of valve, but particularly relates to the slurry valve valve rod mechanism that is used for the mill base slurry valve.
Background technique
But the mill base slurry valve is a kind of valve in the alumina technology system, because the highly basic effect of valve medium, the sealing surface of valve forms easily and scabs, and influences the sealability of valve.Common solution is to unload and the valve that disintegrates, and the sealing surface of valve is gone the scar reparation, to recover the sealability of valve.This mode is operated comparatively complicated, and dismantles easy damage threshold door part repeatedly, is badly in need of improving.
Summary of the invention
But the purpose of the utility model provides a kind of improvement of mill base slurry valve, and this valve should have can simply remove the function that scabs in inside, and has simple in structure and convenience operation.
The technological scheme that the utility model provides is:
Need not to dismantle the slurry valve valve rod mechanism that to repair sealing surface; Comprise valve housing, intert in the middle of the valve housing and cooperate the cylindric valve rod that is in vertical motion with Stem Mut, be formed on flap that valve rod bottom throttle down uses, be fixed in the valve rod middle part and be shaped on the guide plate of axially directed groove, match with guiding groove with the guiding rib of restriction valve rod rotation; It is characterized in that described valve rack is shaped on a guiding rib mounting hole; The coverboard that other has this hole of sealing to use is hinged on the valve rack rotationally, and said guiding rib is installed in the one side towards valve rod of this coverboard; The top of said valve rod also dispose one be used for the lock-up valve stem nut set lever.
Said set lever cooperates with valve rod through worm structure.
The convertible adjustable guiding rib that the utility model provides has been done simple improvement to the guiding rib in original slurry valve valve rod mechanism, and it can be flipped an angle on vertical plane; Under normal situation about using, this guiding rib plays the leading role to valve rod; Going scar when operation, guiding rib is outwards routed up in company with coverboard, set lever again with Stem Mut locked after, valve rod and flap just can freely rotate around axis; Through rotation valve rod flap and valve seat are formed and grind motion, scab, reach the purpose of repairing sealing surface thereby remove; And quick and convenient, simplified operation, reduced rehabilitation cost.

Embodiment
As shown in the figure; This slurry valve valve rod mechanism mainly comprises valve housing, extends perpendicularly in the valve housing and cooperate the cylindric valve rod 3 that is in vertical motion with Stem Mut, be formed on flap 2 that valve rod 3 bottom end closure valve ports use, be fixed at valve rod 3 middle parts and be shaped on the guide plate 4, parallel with valve rod 3 and match with the guiding rib 5 of restriction valve rod 3 rotations (valve rod can only move axially) with guiding groove 20 of axially directed groove 20.
When opening/shutting valve, rotation earlier is positioned at the handwheel 9 on the valve housing, and the gear-box 8 that is positioned on the support 7 is given Stem Mut 11 with transmission of power; Because guiding rib 5 and guide plate 4 effect of working in coordination make valve rod be restricted around the rotation of axial direction, therefore the drive lower valve rod 3 at Stem Mut 11 moves on axial direction; When the flap 2 on valve rod 3 arrived specified position, the keying of valve was accomplished.
The structure of above structure and existing valve roughly the same.
The improvement of the utility model is: described valve housing is shaped on a guiding rib mounting hole; The coverboard 6 that other has this hole of sealing to use is hinged on (visible set screw 4-1 and hinge 21 among the figure) on the valve housing rotationally, and said guiding rib 5 is fixedly mounted on the one side towards valve rod of this coverboard; The top of said valve rod also dispose one be used for the lock-up valve stem nut set lever 10, this set lever cooperates with valve rod through worm structure (internal thread of making on the handle matches with the outside thread of valve rod external peripheral surface).
When going the scar operation, rotate handwheel 9 earlier and make flap 2 close port (this moment, the sealing surface of flap 2 closely contacted with the sealing surface of valve seat 1); Unclamp set screw 6 then, guiding rib 5 is overturn left, guiding rib 5 is separated with guide plate 4, removed of the restriction of 5 pairs of valve rods 3 of guiding rib around rotational; Then tighten set lever 10, valve rod 3, set lever 10 and Stem Mut 11 are tightened be integral, valve rod has been realized the qualification on the axial direction; Rotate handwheel 9 again; Drive valve rod and flap rotation through the umbrella gear group in the gear-box 8 (Stem Mut is being fixed by umbrella gear central authorities wherein); The sealing surface of the sealing surface of flap 2 and valve seat 1 grinds with regard to forming friction relatively each other; Sealing surface obtains reparation through after grinding, and has recovered the sealability of valve.
Claims (2)
1. need not to dismantle the slurry valve valve rod mechanism that to repair sealing surface; Comprise valve housing, intert in the middle of the valve housing and cooperate the cylindric valve rod (3) that is in vertical motion with Stem Mut (11), be formed on flap (2) that valve rod bottom throttle down uses, be fixed in the valve rod middle part and be shaped on the guide plate (4) of axially directed groove (20), match with guiding groove with the guiding rib (5) of restriction valve rod rotation; It is characterized in that described valve rack is shaped on a guiding rib mounting hole; The coverboard (6) that other has this hole of sealing to use is hinged on the valve rack rotationally, and said guiding rib is installed in the one side towards valve rod of this coverboard; The top of said valve rod also dispose one be used for the lock-up valve stem nut set lever (10).
2. according to claim 1ly need not to dismantle the slurry valve valve rod mechanism that to repair sealing surface, it is characterized in that said set lever cooperates with valve rod through worm structure.
