Abstract
The invention discloses a rotary valve switch signal output mechanism device which is characterized in that a switch hand wheel is matched with a valve rod nut through a key i; the valve rod nut is installed in a valve cover support hole and is positioned by a thrust bearing; a valve rod is screwed in a valve rod nut, is used for fixing an internal gear sleeve, and is fixed on the valve cover through a set screw; a small gear is fixed on an inner ring through a shaft; the inner ring is fixed on the valve rod nut through a key ii; a rotation inner gear sleeve passes through the valve rod nut, is installed and fixed on the inner gear sleeve, is meshed with the small gear, and is fixed with an elastic retainer ring for a shaft to prevent the meshed parts of the gears from separation; two stroke iron blocks are inserted in a T-shaped groove on the rotation inner gear sleeve and are fixed with a top thread; and a stroke switch is fixed on the inner gear sleeve through a fastening piece. According to the invention, a circle angle can be adjusted randomly by the stroke iron blocks to achieve the accuracy of valve switch signal output, and the problem that the stroke switch can not be installed by a valve is solved.
Description
Technical field
The present invention relates to valve, in particular, relate to a kind of rotary type valve switch signal output mechanism device.
Background technique
The present invention relates to valve.Existing valve mechanism chief component part has valve body, sealing seat, flashboard, valve rod, filler, filler pressing sleeve, valve gap, Stem Mut, thrust bearing, key, bolt, nut and switch handwheel etc.Two seal rings are welded on the body cavity passage, and tightly on seal ring, valve rod passes valve gap to valve rod connection flashboard ， Bing Wedged, and valve gap passes through bolt, fastening nuts on valve body.Stuffing box packing is contained in the Stuffing box, and under bolt, nut, hold-down grid, filler pressing sleeve effect, sealed valve stem is not revealed the interior medium of valve to the external world.Stem Mut screws on the valve rod, by thrust bearing and bearing gland Stem Mut is fixed on the valve gap upper end.The switch handwheel is installed on the valve rod.Handwheel drives the Stem Mut revolution, and under threaded function, valve rod drives flashboard and moves up and down, valve closing when flashboard moves to lower dead centre, flowing medium blocking-up.Valve opening when flashboard moves to upper dead center, the medium circulation.
The greatest drawback of valve is: the one, valve under the state of opening and closing, do not have switched electrical signal output and by cable with electrical signal transfer to the control room, can't judge unlatching or the closed condition of valve.The 2nd, can't the switched electrical signal output mechanism be installed at the valve gap support, be subjected to the valve design size restrictions.
Summary of the invention
The problem that exists in order to solve above-mentioned prior art the invention provides a kind of rotary type valve switch signal output mechanism device that is installed in the turnstile below.This device buting iron can adjustment stroke, the switched electrical signal accurate positioning, and working stability is reliable, dwindles the valve height dimension.
The present invention is that the technological scheme that the existing technical problem of solution adopts is: a kind of rotary type valve switch signal output mechanism device, be installed in valve gap support top, mainly comprise two range-adjustable buting iron, two limit switches, one group of differential gear rotary disk assembly.The switch handwheel matches with Stem Mut by key ⅰ, and Stem Mut is packed in the valve gap bracket holes, is located by thrust bearing.Valve rod screws in the Stem Mut, the fixed annulus cover, be fixed on the valve gap by Cock screw, small gear is fixed on the interior ring by axle, and interior ring is fixed on the Stem Mut by key ⅱ, the revolution inner gear housing, pass Stem Mut, be installed in above the fixed annulus cover, and and pinion, and fix with circlip for shaft, prevent that the gear mate from throwing off.Two stroke buting iron insert in the T-shaped groove that turns round on the inner gear housing, and fix with jackscrew.Position limit switch puts by the fastening piece fixed annulus.
Working principle of the present invention is: handwheel drives the rotation of Stem Mut clockwise direction by key ⅰ, and valve rod moves down, valve closing, and the handwheel counterclockwise rotation, this moment, valve rod moved up valve opening.During the Stem Mut revolution, the small gear that drives on the interior ring by key ⅱ turns round, small gear while and fixed annulus cover, the engagement of revolution inner gear housing, because the poor every public affairs of small gear that cause of the number of teeth of two internal gears circle, the revolution inner gear housing only turns the 1/n circle, the stroke buting iron that is fixed on the revolution inner gear housing also only turns the 1/n circle, calculate the handwheel revolution number of turns according to valve opening height and valve rod pitchometer, be turned back to the rotating angle of fully open position stroke buting iron by the poor handwheel that calculates of the number of teeth of two internal gears, the stroke buting iron is run on the contact of position limit switch, at this moment, cable by position limit switch passes on the remote signal lamp, shows the state that valve opens or closes.
The remarkable beneficial effect that the present invention has is: the stroke buting iron can arbitrarily be adjusted the accuracy that the circumference angle reaches valve switch signal output, solves the problem that valve can't be installed position limit switch.
Description of drawings
