Abstract
The utility model discloses an adjusting butterfly valve. The adjusting butterfly valve comprises an actuating mechanism I, wherein the actuating mechanism I comprises a controller I, a butterfly valve plate I and a butterfly valve plate shaft I, and the butterfly valve plate I is connected with the controller I through the butterfly valve plate shaft I. The adjusting butterfly valve is characterized by further comprising an actuating mechanism II which comprises a controller II, a butterfly valve plate II and a butterfly valve plate shaft II, and the butterfly valve plate II is connected with the controller II through the butterfly valve plate shaft II. The butterfly valve plate I is further fixedly provided with a butterfly valve plate shaft sleeve, and reinforced ribs are arranged between contact surfaces of the butterfly valve plate shaft sleeve and the butterfly valve plate I, between contact surfaces of the butterfly valve plate shaft I and the butterfly valve plate I, and between contact surfaces of the butterfly valve plate shaft II and the butterfly valve plate II. The adjusting butterfly valve has the advantages of being good in sealing properties, simple in structure, small in size, light in weight and low in cost, and prolonging service life. In addition, when a pipeline is used in small flow mode, a correct flow characteristic curve also can be obtained, and the adjusting butterfly valve mainly applies to an adjusting butterfly valve of a bivalve plate.
Description
Technical field
The utility model relates to the butterfly valve field, relates in particular to a kind of adjusting butterfly valve.
Background technique
At present, regulate butterfly valve, in many fields such as oil, chemical industry, metallurgy, water power, obtain using very widely as a kind of parts that are used for realizing pipe-line system break-make and flow control.In known butterfly valve technology, the use of butterfly valve only is fit to the pipeline of big flow, and butterfly valve can't obtain concrete traffic characteristic curve at flow hour, causes the gained data incorrect, influences efficient.Therefore being badly in need of a kind of improved technology solves existing this problem in the existing technology.
Summary of the invention
The purpose of the utility model provides a kind of adjusting butterfly valve.
The technological scheme that the utility model adopts is:
Regulate butterfly valve; Comprise actuator's I, said actuator I comprises controller I, butterfly valve plate I and butterfly valve shaft I, and said butterfly valve plate I is connected with the controller I through butterfly valve shaft I; Also comprise actuator's II; Said actuator II comprises controller II, butterfly valve plate II and butterfly valve shaft II, and said butterfly valve plate II is connected with the controller II through butterfly valve shaft II, also is fixed with butterfly valve plate axle sleeve on the said butterfly valve plate I.
Be provided with stiffening rib between said butterfly valve plate axle sleeve and the butterfly valve plate I surface of contact, be provided with stiffening rib between said butterfly valve shaft I and the butterfly valve plate I surface of contact, be provided with stiffening rib between said butterfly valve shaft II and the butterfly valve plate II surface of contact.
The utility model has the advantages that: good seal performance, increase the service life, simple in structure, volume is little in light weight, and cost is low, when the pipeline small flow uses, also can obtain correct traffic characteristic curve, is mainly used in the bivalve plate and regulates butterfly valve.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model.
Wherein: 1, controller I, 2, butterfly valve plate I, 3, butterfly valve shaft I, 4, the controller II, 5, butterfly valve plate II, 6, butterfly valve shaft II, 7, butterfly valve plate axle sleeve, 8, stiffening rib.
Embodiment
As shown in Figure 1, the adjusting butterfly valve of the utility model comprises actuator's I; Said actuator I comprises controller I 1, butterfly valve plate I 2 and butterfly valve shaft I 3, and said butterfly valve plate I 2 is connected with controller I 1 through butterfly valve shaft I 3, also comprises actuator's II; Said actuator II comprises controller II 4, butterfly valve plate II 5 and butterfly valve shaft II 6, and said butterfly valve plate II 5 is connected with controller II 4 through butterfly valve shaft II 6, also is fixed with butterfly valve plate axle sleeve 7 on the said butterfly valve plate I 2; Be provided with stiffening rib 8 between said butterfly valve plate axle sleeve 7 and butterfly valve plate I 2 surface of contact, be provided with stiffening rib 8 between said butterfly valve shaft I 3 and butterfly valve plate I 2 surface of contact, be provided with stiffening rib 8 between said butterfly valve shaft II 6 and butterfly valve plate II 5 surface of contact; Good seal performance increases the service life, and is simple in structure; Volume is little in light weight, and cost is low, when the pipeline small flow uses; Also can obtain correct traffic characteristic curve, be mainly used in the bivalve plate and regulate butterfly valve.
Working principle:
When gas flow hour, actuator's II action is regulated butterfly valve plate II 5 opening angles through butterfly valve shaft II 6; When gas flow was big, actuator's I was through butterfly valve shaft I 3 control butterfly valve plate I 2 opening angles.
This product is used to change the traffic characteristic curve (performance) of heavy caliber adjustment butterfly valve in little aperture (0-30 °), and actuator's I is regulated (corresponding corresponding discharge) to butterfly valve plate I 2 from the 0-100% aperture; Again by actuator's II to butterfly valve plate II 5 when the 0-30% aperture is regulated, just can use actuator's I to regulate butterfly valve plate I 2 simultaneously, change traffic characteristic curve.
