Abstract
The utility model discloses a butterfly valve with an adjustable indicator. A worm wheel is connected with a valve driving shaft through connectors and keys, so the linkage of the worm wheel and the driving shaft is realized, a clamp groove is arranged on the worm wheel, the adjustable indicator is connected with the worm wheel, and the adjustable indicator comprises an special-shaped spring and an indication cover; the upper surface of the indication cover is provided with a pointer, the lower surface of the indication cover is provided with a clamp block, and both ends of a long shaft of the clamp block are respectively provided with a notch; the middle position of the special-shaped spring is provided with two pressure springs, and a bending part matched with the clamp block is arranged on each pressure spring; and the indication cover is inserted into the special-shaped spring and is fastened and connected with the special-shaped spring after rotation. The butterfly valve has a simple structure and uses few components, and the fastening effect can be reached only through the matched use of the two components: the special-shaped spring and the indication cover, so the production cost is greatly reduced, in addition, the special-shaped spring can be loosened or fastened only through rotating the indication cover when the indicator is installed or regulated, and the operation is more convenient and fast.
Description
Technical field
The utility model relates to a kind of valve, specifically is a kind of butterfly valve that has adjustable indicator.
Background technique
Butterfly valve is meant that closure member (flap or butterfly plate) is a disk, rotates a kind of valve that reaches open and close around valve shaft, and main rising cut off and throttling usefulness on pipeline.The butterfly valve open-shut device is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the purpose that opens and closes or regulate.
Existing reed valve dish plate indicator of opening complex structure generally includes chassis, spring, indication lid; In its installation process, at first spring is snapped in the groove in the indicating wheel, the chassis is set below spring again, the indication lid is located at the spring top, by fastening piece the three is fixed at last; After needs are adjusted, during the check and correction indicator, need first loosening fasteners, adjust the orientation of indication lid, securable fastener again.This indicator structure complexity, required part is more, so increased cost, and install, the dismounting trouble, be unfavorable for realizing quick adjustment or check and correction to pointer position.
The model utility content
The model utility purpose: the purpose of this utility model is in order to overcome the deficiency of existing product technology, to provide a kind of simple in structure, the easy to operate butterfly valve that has adjustable indicator.
Technological scheme: in order to solve the problems of the technologies described above, a kind of butterfly valve that has adjustable indicator that the utility model provides, worm gear is connected with the valve driving axle with key by connector, thereby realize the interlock of worm gear and live axle, worm gear is provided with draw-in groove, adjustable indicator is connected with worm gear, it is characterized in that: described adjustable indicator comprises heterotypic spring and indication lid; Indication covers the surface and is provided with pointer, and lower surface is provided with fixture block, and the major axis two ends of fixture block are respectively equipped with awkward-sounding; The heterotypic spring intermediate portion is provided with the twice stage clip, is provided with the bending part that matches with fixture block on stage clip; The indication lid inserts heterotypic spring, is fastenedly connected with it after rotation.
Distance between the described two bending part end points is greater than the distance between the twice stage clip.
The distance at described fixture block major axis two ends is greater than the distance between the two bending part end points.
Described fixture block minor axis two ends distance is less than the distance between the twice stage clip.
Described awkward-sounding and stage clip are complementary.
Beneficial effect: compared with prior art, a kind of butterfly valve that has adjustable indicator that the utility model provides, adjustable indicator and live axle interlock, the accurate indication that realization opens and closes the dish plate, and this adjustable indicator structure is simple, the use parts are few, only needing heterotypic spring and indication to cover two parts is used and can reaches fastening effect, this not only greatly reduces cost of production, and when installing or adjust indicator, only need rotation indication lid can unclamp or fastening heterotypic spring, make operation more convenient.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, should understand these embodiments only be used to the utility model is described and be not used in the restriction scope of the present utility model.
The utility model heterotypic spring 1 outer ring as shown in Figure 1 is circular arc, is complementary with draw-in groove 4 structures shown in Figure 7; Deformed spring 1 comprises twice stage clip 101,102, and to be parallel to twice stage clip 101,102 and to be the symmetry axis bilateral symmetry through the axle of the mid point of distance between them.Be provided with the bending part reverse with described symmetry axis at twice stage clip 101,102 middle parts, the distance between the two bending part end points is greater than the distance between the twice stage clip 101,102.
Extremely shown in Figure 8 as Fig. 5, because fixture block 202 minor axis two ends distance is less than the distance between the twice stage clip 101,102, so fixture block 202 can insert deformed spring 1 smoothly; The distance at major axis two ends is greater than the distance between the two bending part end points, cover 2 so only need rotate indication, fixture block 202 major axis two ends are aimed at two bending part end points, and drive bending part twice stage clip 101,102 is ejected, make the adjustable indicator of the utility model be anchored in draw-in groove shown in Figure 74 structures.
This adjustable indicator structure is simple, uses parts few, only needs heterotypic spring 1 to cover 2 two parts with indication and is used.When adjustable indicator is installed, only need compress stage clip 101,102, heterotypic spring 1 draw-in groove 4 of just packing into smoothly will indicate then and cover 2 and insert deformed springs 1 and also rotate, utilize fixture block 202 that stage clip is ejected, thus make adjustable indicator be fastenedly connected with draw-in groove 4.When needs are done position adjustment or check and correction to indicator, rotation indication earlier covers 2, make fixture block 202 major axis and stage clip 101,102 parallel and take out indication and cover 2, compress stage clip 101,102 then, stage clip 101,102 is tightened up, can in draw-in groove 4, slide, rotate with check and correction pointer direction or with deformed spring 1 and take out.
A kind of butterfly valve that has adjustable indicator of providing of the utility model as shown in Figure 9, worm gear 3 is provided with the draw-in groove 4 that cooperates with adjustable indicator, adjustable indicator is placed in the draw-in groove 4, thereby adjustable indicator is connected with worm gear 3; Worm gear 3 is connected with valve driving axle 8 with key 6,7 by connector 5, thereby realizes the interlock of worm gear 3 and live axle 8, realizes the indication of state that the dish plate is opened and closed.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
