The utility model is provided with a spiral lifting device, which can be matched with the upper end part of a separating cover (3) and lift with the rotating of a outer magnetic rotor (2), and the spiral lifting device is arranged in the center hole of the upper end of a driving wheel which is composed of the combined outer magnetic rotor and a handwheel (1). The utility model is applied to a wholly closed magnetically transmission valve.
Description
Technical field
The utility model relates to the method and the device of indication valve plate position in the Totally-enclosed magnetic force valve opening-closing process.
Background technique
Existing Totally-enclosed magnetic force valve be the magnetic drives valve structure as shown in Figure 1, by the interior magnet rotor 4 in valve body 6, blocking-up and the valve plate 7 of opening valve channel, lifting screw that valve plate connects 5, separation sleeve that valve body joins 3, the separation sleeve, separation sleeve outward outer magnet rotor 2 and the handwheel 1 that is coupled to outer magnet rotor constitute.Rotate handwheel 1 and drive outer magnet rotor 2 and rotate, outer magnet rotor magnetic force penetrates the interior magnet rotor 4 that separation sleeve 3 drives the tool internal threads and rotates, and the lifting screw 5 of magnet rotor is just done the ascending, descending campaign by screw drives in being matched with, the unlatching of realization valve or close.
The magnetic drives valve has been cancelled the filler at valve rod position, and the stationary seal position relies on separation sleeve to realize static seal with sealing gasket, does not therefore have leakage fully; Based on these characteristics, that this valve is specially adapted to is inflammable, explosive, in the pipeline of toxicity, radiating medium.
Yet the magnetic drives valve is owing to the existence of separation sleeve, and the lifting of inner valve rod externally can't be observed, and promptly can not observe open and-shut mode and the opening degree of knowing valve, and this brings hidden danger to normal running and safety in production; Just because so, present magnetic drives valve fails to be applied in a big way.
Summary of the invention
The utility model will solve the problem that existing magnetic drives valve can not externally be observed valve opening state and opening degree, Totally-enclosed magnetic force valve opening degree indicating device of the present utility model is provided for this reason, adopts this device can make the magnetic force movable valve externally observe valve open and-shut mode and opening degree.
For addressing the above problem, its special way of the technical solution adopted in the utility model is provided with described outside magnet rotor rotating and the spiral lift device of lifting of with separation sleeve upper end portion cooperating by outer magnet rotor and handwheel in the center hole in conjunction with the driving wheel upper end portion that constitutes at described Magnetic valves.
The described spiral lift device that cooperates with the separation sleeve upper end portion can be meant: the indication nut that is provided with the tool internal thread, the separation sleeve upper end is fixed with double-screw bolt and cooperates with described indication nut, described indication nut outer wall offers axial channel, and the upper end portion of described driving wheel center hole is fixed with the feather key position in described guide groove.
The described spiral lift device that cooperates with the separation sleeve upper end portion also can be meant: be provided with the externally threaded indication double-screw bolt of tool, this indication double-screw bolt outer wall offers axial channel, and the separation sleeve upper end is fixed with the antirotation keys position in described guide groove.
Driving wheel described in the utility model is made of the handwheel of outer magnet rotor and the combination of upper end portion institute thereof, and the two can adopt all multimode combinations such as comprising the weldering knot, and the magnet rotor upper end can extend upward outside the junction, also can not extend; Upwardly extending, the center hole of described driving wheel upper end portion then is an outer magnet rotor upper end portion center hole, does not extend, and the center hole of described driving wheel upper end portion then is the handwheel center hole.
The utility model is owing to be provided with the spiral lift device that cooperates with the separation sleeve upper end portion in the center hole of the driving wheel upper end portion that described Magnetic valves is made of outer magnet rotor and handwheel combination, when rotating handwheel, outer magnet rotor rotates, magnet rotor rotates in magnetic force penetrates drive, rise with the lifting screw of interior magnet rotor screw-thread fit, motion is fallen, be connected in the valve plate liter of lifting screw, motion is fallen, realize valve opening or close, indication piece liter in the while spiral lift device, motion is fallen, this indication piece can be described indication nut or indication double-screw bolt, so the utility model can be known the unlatching of valve or close and opening degree the acquisition opening of valves from visual observation, close, the information of opening degree.

Embodiment
Embodiment one
Totally-enclosed magnetic force valve open degree indicating device, as shown in Figure 2, by valve body 6, blocking-up and the valve plate 7 of opening valve channel, lifting screw that valve plate connects 5, separation sleeve that valve body joins 3, interior magnet rotor 4 in the separation sleeve, be provided with the indication nut 8 of tool internal thread in the outer magnet rotor 2 that separation sleeve is outer and the outer magnet rotor 2 of this valve of handwheel 1 formation that is coupled to outer magnet rotor and the center hole of handwheel 1 in conjunction with the driving wheel upper end portion that constitutes, indication nut 8 outer walls offer axial channel, be fixed with in separation sleeve 3 upper ends a double-screw bolt 9 with indication nut 8 cooperate, described center hole upper end portion is fixed with a feather key 10 positions in the guide groove of described indication nut.Adopt this device can realize the indication of Totally-enclosed magnetic force valve open degree,, obtain the information of valve closing or unlatching and opening degree promptly from the ascending, descending of visual observation indication nut 8.
During throttle down, clockwise direction rotates handwheel 1, and outer magnet rotor 2 rotates together, by magnetic force penetrate drive in the rotation of magnet rotor 4 clockwise directions, do not rotate with the lifting screw 5 of interior magnet rotor 4 left hand thread engagement thereby make the descending motion throttle down; Meanwhile, feather key 10 rotates with handwheel 1 and drives the rotation of 2 indication nuts, 9 clockwise directions, and indication nut 9 cooperates with double-screw bolt 8 right-handed threads, and double-screw bolt 9 is fixed on fixing separation sleeve 3 upper ends, and indication nut 8 is just done descending motion, the indication valve closing.
