Abstract
The utility model relates to a signal gate valve which comprises a valve body, a gate plate, a valve rod, a valve cover, a valve rod nut and an operating hand wheel, wherein the gate plate is arranged in the valve body; the valve rod is arranged above the gate plate; the valve cover is fixed on the valve body; and the valve rod nut and the operating hand wheel are arranged on the valve rod; the valve rod passes through the valve cover, the valve rod nut and the operating hand wheel and is exposed outside the operating hand wheel which is positioned above the valve cover, a frame-shaped portal frame is arranged between the operating hand wheel and the valve cover, and a signal box is arranged on the frame-shaped portal frame. The signal gate valve is characterized in that the valve rod nut is provided with an extension end extending to the signal box, the outer side of the extension end is sleeved with a rotary ring which is matched with the extension end by screw thread, the outer side of the rotary ring is fixedly provided with a trigger arm, and a rotation stopping device matched with the trigger arm and micro switches arranged above and below the trigger arm are arranged on the signal box. With the technical scheme, the signal gate valve has the effect of simpler structure that mechanical actions are converted to electric signals.
Description
Technical field
The utility model relates to a kind of Signal sluice valve.
Background technique
Traditional Signal sluice valve, generally include valve body, be installed in flashboard in the valve body, be installed in the flashboard top valve rod, be fixed on valve gap on the valve body, be installed in Stem Mut and operation handwheel on the valve rod, valve rod passes valve gap, Stem Mut and operation handwheel and exposes outside the operation handwheel, the operator wheel is positioned at the valve gap top, be provided with frame type portal frame between operation handwheel and the valve gap, described frame type portal frame is provided with the signal box, and it is by converting machinery action to electrical signal to detect the keying state of gate valve.Yet existing Signal sluice valve, its machinery action convert the structure more complicated of electrical signal to.
Summary of the invention
At the deficiency that prior art exists, the simple more Signal sluice valve of the structure that provides a kind of machinery action to convert electrical signal to is provided the purpose of this utility model.
For achieving the above object, the utility model provides following technological scheme: a kind of Signal sluice valve, comprise valve body, be installed in the flashboard in the valve body, be installed in the valve rod of flashboard top, be fixed on the valve gap on the valve body, be installed in Stem Mut and operation handwheel on the valve rod, valve rod passes valve gap, Stem Mut and operation handwheel also expose outside the operation handwheel, the operator wheel is positioned at the valve gap top, be provided with frame type portal frame between operation handwheel and the valve gap, described frame type portal frame is provided with the signal box, it is characterized in that: described Stem Mut is provided with the extending end that extends to the signal box, the described extending end outside is arranged with swivel becket, described swivel becket and extending end are by the screw-thread fit setting, the swivel becket outside is set with trigger arm, and described signal box is provided with the whirl-stop device that is equipped with trigger arm and is arranged on the trigger arm, following two sides' sensitive switch.
By adopting technique scheme, rotating handwheel rises valve rod or descends gate valve is opened or closing operation the time, Stem Mut rotates, because the whirl-stop device of trigger arm and swivel becket and extending end are by the effect of screw-thread fit, swivel becket drives trigger arm and with Stem Mut relative moving up and down is taken place, sensitive switch on or below the shake-up trigger arm, just can produce the keying state of electrical signal detection gate valve, therefore, technical solutions of the utility model have the simple more effect of structure that machinery action converts electrical signal to.
The utility model further is set to: described signal box is provided with and is the bar hole that vertical direction is provided with, and described trigger arm top is located in the bar hole, and described bar hole constitutes the whirl-stop device of trigger arm.
By adopting technique scheme, bar hole carries out to trigger arm that left and right directions is spacing can not to rotate it, and trigger arm can move up and down in bar hole.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model Signal sluice valve example structure figure;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, the disclosed Signal sluice valve of the utility model, comprise valve body 1, be installed in the flashboard 2 in the valve body 1, be installed in the valve rod 3 of flashboard 2 tops, be fixed on the valve gap 4 on the valve body 1, be installed in Stem Mut 5 and operation handwheel 6 on the valve rod 3, valve rod 3 passes valve gap 4, Stem Mut 5 and operation handwheel 6 also expose outside operation handwheel 6, operation handwheel 6 is positioned at valve gap 4 tops, be provided with frame type portal frame 7 between operation handwheel 6 and the valve gap 4, described frame type portal frame 7 is provided with signal box 8, described Stem Mut 5 is provided with the extending end that extends to signal box 8, the described extending end outside is arranged with swivel becket 9, described swivel becket 9 and extending end are by the screw-thread fit setting, swivel becket 9 outsides are set with trigger arm 10, and described signal box 8 is provided with the whirl-stop device that is equipped with trigger arm 10 and is arranged on the trigger arm 10, following two sides' sensitive switch 11.By adopting technique scheme, rotating operation handwheel 6 rises valve rod 3 or descends gate valve is opened or closing operation the time, Stem Mut 5 rotates, because the whirl-stop device of trigger arm 10 and swivel becket 9 and the effect of extending end by screw-thread fit, swivel becket 9 drives trigger arm 10 and with Stem Mut 5 relative moving up and down is taken place, sensitive switch 11 on or below the shake-up trigger arm 10, just can produce the keying state of electrical signal detection gate valve, therefore, technical solutions of the utility model have the simple more effect of structure that machinery action converts electrical signal to.
The whirl-stop device of technical solutions of the utility model trigger arm 10 can adopt various different modes settings, present embodiment preferably is set to: described signal box 8 is provided with and is the bar hole 81 that vertical direction is provided with, described trigger arm 10 tops are located in the bar hole 81, and described bar hole 81 constitutes the whirl-stop device of trigger arm 10.By adopting technique scheme, 81 pairs of trigger arms of bar hole 10 carry out that left and right directions is spacing can not to rotate it, and trigger arm 10 can move up and down in bar hole 81.
