Abstract
The utility model discloses a butterfly valve. The butterfly valve comprises a valve body, a tubular switch, a gear and an arc-shaped rack, wherein the valve body is an outer threaded pipe; the tubular switch is an internal threaded pipe; the valve body is matched with the tubular switch; the arc-shaped rack is arranged between the valve body and the tubular switch, and matched with the rear; the lower end of the gear penetrates through the valve body, and is fixedly connected with a blade plate. According to the butterfly valve disclosed by the utility model, an original switch which is vertical to the valve body is canceled, so that the butterfly valve is convenient to install and space-saving; moreover, an accident does not easily happen.
Description
Technical field
The utility model relates to valve field.
Background technique
The switch of current butterfly valve generally is designed to the part of hanging down as for valve body, not only takies larger space but also easily causes the accident.
The model utility content
The utility model provides a kind of butterfly valve, has removed the switch of past perpendicular to valve body, is convenient to install saved space, and is not prone to accident.
The purpose of this utility model is carried out specific implementation by the following technical programs:
A kind of butterfly valve, comprise valve body, tubular switch, gear and arc-shaped rack,
Described valve body is male-pipe, and described tubular switch is riffled tube, and described valve body coordinates with described tubular switch,
Described arc-shaped rack is arranged between described valve body and described tubular switch and coordinates with described gear,
Described gear lower end is fixedly connected with impeller through described valve body.
Further, the top in the middle of described valve body is provided with chute, and the circumferential width of described chute is corresponding with the circumferential width of described arc-shaped rack, and described chute and described arc-shaped rack are slidably matched.
Further, in the neutral position of described tubular switch, around inwall, be provided with slideway, the axial width of described slideway is corresponding with the axial width of described arc-shaped rack, and described slideway and described arc-shaped rack are slidably matched.
Further, the thickness of described arc-shaped rack is greater than the degree of depth of described slideway.
The utility model, by the design to tubular switch, has removed the switch of past perpendicular to valve body, is convenient to install saved space, and is not prone to accident.
The accompanying drawing explanation
Below according to drawings and embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the described a kind of butterfly valve of the utility model embodiment.
Fig. 2 is the structural representation of the described valve body of the utility model embodiment.
Fig. 3 is the structural representation that the described valve body of the utility model embodiment coordinates with described arc-shaped rack.
Fig. 4 is the structural representation of the described tubular switch of the utility model embodiment.
Embodiment
As Figure 1-4, the described a kind of butterfly valve of the utility model embodiment, comprise valve body 1, tubular switch 2, gear 3 and arc-shaped rack 4,
Arc-shaped rack 4 is arranged between valve body 1 and tubular switch 2 and coordinates with gear 3,
Gear 3 lower ends are fixedly connected with impeller 5 through valve body 1.
Top in the middle of valve body 1 is provided with chute 11, and the circumferential width of chute 11 is corresponding with the circumferential width of arc-shaped rack 4, and chute 11 is slidably matched with arc-shaped rack 4.
Neutral position at tubular switch 2 is provided with slideway 21 around inwall, and the axial width of slideway 21 is corresponding with the axial width of arc-shaped rack 4, and slideway 21 is slidably matched with arc-shaped rack 4.
The thickness of arc-shaped rack 4 is greater than the degree of depth of slideway 21.
During use, rotate tubular switch 2, tubular switch 2 drives arc-shaped rack 4 and then driven gear 3 and butterfly plate 5 and realizes switching function.
The utility model, by the design to tubular switch, has removed the switch of past perpendicular to valve body, is convenient to install saved space, and is not prone to accident.
