Abstract

The utility model relates to a measuring device for displaying the turn-on degree of a valve. The present valve don't have a mark to display the turn-on degree of the valve and a user only judges according to experience. The utility model is composed of a driving wheel 1, a base 2 and a driven wheel, which is characterized in that the driving wheel is fixedly connected to a valve spindle; the base 2 is sheathed on a valve cap; the driven wheel has a definite proportion transmission relation with the driving wheel; the driven wheel has graduations which can display the situation where the driving wheel is driven by the valve spindle to rotate through an upper cover or other reference substances. The definite proportion transmission can be gear transmission, belt transmission, chain transmission, worm wheel and worm transmission and wheel train pull rope transmission. Because the turn-on degree of a valve port is displayed, flow quantity can be adjusted accurately and waste is reduced. The utility model can be arranged on the valves of various liquid pipelines.

Description

Valve opener by seight

The utility model is disclosed to be a kind of utensil that shows the valve opening degree.

The scale that does not show its opening degree on the existing valve, valves such as ball valve rule of thumb judge only according to valve rod rising degree, and the gate valve class is because of no valve rod rising phenomenon, so more difficultly conclude the situation of wherein opening.

The purpose of this utility model provides a kind of mechanical counter tool that shows the valve opening degree.

Content of the present utility model comprises loam cake 1, is enclosed within the base 2 on the valve upper press cover, and the driving wheel that connects firmly mutually with valve rod and fixed follower than transmission is arranged with driving wheel has scale on this follower, can show the follower rotation situation by objects of reference such as loam cakes.

Fixed than transmission between driving wheel and the follower has following implementation: 1, gear transmission, 2, the band transmission, 3, chain-driven, 4, the worm and gear transmission, 5, the transmission of train stay cord.

Effect of the present utility model is: rotate to drive by valve rod and look out device, show the valve opening degree, with accurate adjustment reasonable flow, cut the waste, thereby reach energy-saving and cost-reducing effect.

Fig. 1 is that three gear-driven valves are looked out the device structural representation.

Fig. 2 looks out the display mode of making scale on the device with numeral for valve.

Fig. 3 is that the A of base Fig. 1 when being connected with six side's valve gaps is to view.

Fig. 4 is that two gear-driven valves are looked out the device structural representation.

Valve when Fig. 5 is synchronous cog belt or chain-driven is looked out the device structural representation.

Fig. 6 looks out the device structural representation for the valve of worm and gear transmission.

Fig. 7 is the plan view of Fig. 6.

Fig. 8 looks out the device structural representation for the valve of train stay cord transmission.

Fig. 9 removes plan view behind loam cake and the base for Fig. 8.

Embodiment one

Form by loam cake 1, base 2, positioning screwn 3, breast wheel 4, driving wheel 5, follower 6, wherein driving wheel 5, breast wheel 4, follower 6 are gear, it between the three engagement driving, driving wheel 5 and valve rod are for connecting firmly, base 2 is affixed with valve gap, and follower 6 is marked with scale, can show that valve rod drives the angle that driving wheel turns over, (referring to Fig. 3) is the valve port opening degree, is applicable to that it is the bigger occasion of follower that valve rod rotates the number of turns more.

Embodiment two:

Form by loam cake 1, base 2, driving wheel 7, follower 8, wherein driving wheel 7, follower 8 is an engagement driving in the gear, driving wheel 7 connects firmly with valve rod, base 2 is affixed with valve gap, be carved with scale on the follower 8, can show that the angle that valve rod drive driving wheel 7 turns over is the valve port opening degree, this type is applicable to that it is the less occasion of follower that valve rod rotates the number of turns less.Follower 8 is hinged with valve seat.

Embodiment three: be made up of loam cake 1, base 2, positioning screwn 3, driving wheel 9, driving belt 10, follower 11.Wherein driving wheel 9 is affixed with valve rod, follower 11 is fixing by the positioning screwn between loam cake 1 and the base 23, when if driving wheel 9 followers 11 are the profile of tooth belt wheel, driving belt 10 is a synchronous cog belt, shows that by the scale on the follower 11 angle that palace gate bar drive driving wheel 9 turns over is the valve port opening degree.

Embodiment four:

Close with embodiment three, change driving wheel 9 and follower 11 into sprocket wheel, change driving belt 10 into chain, promptly become another embodiment of the present utility model.

Embodiment five:

Form by loam cake 1, base 2, worm screw 12, worm gear 13 and with the articulated elements of base 2, by driving wheel is worm screw 12, and it is worm gear 13 that follower is passed in the rotation of valve rod, and the follower high scale is in order to show the valve port opening degree, worm screw 12 is connected with valve rod, and base 2 is affixed with valve gap.

Embodiment six:

By loam cake 1, base 2, stationary axle 14(2) stay cord 15, friction wheel 16, central shaft 17, driving wheel 18, follower 19 is formed, stay cord 15 two ends are fixed on the follower 19, by the driving wheel 18 pivoting frictions wheel that is fixed on the valve rod, on driving wheel 18 and the friction wheel uniform projection is arranged, twining stay cord 15 on the central shaft 17 of friction wheel 16, the rotation of friction wheel makes two ends, one end of rope unclamp end tension, cause follower 18 to rotate, follower and base 2 are hinged, be carved with scale on the follower 18, to show that valve rod drives the angle that driving wheel turns over, i.e. valve port opening degree.
