Abstract
The utility model discloses a novel low resistance butterfly valve, including valve body, sealing layer, pivot and valve plate, the aperture of valve body is located to expand towards the valve plate respectively from both sides kneck, forms expansion portion in valve plate department, the valve plate is the fusiformis structure. Compared with the prior art, the utility model, through the mode of enlarging the valve body latus rectum and changing the valve plate structure, can reduce the resistance of fluid in the valve body effectively, promoted the result of use of butterfly valve, possessed splendid application prospect.
Description
Technical Field
The utility model relates to a butterfly valve, concretely relates to novel low resistance butterfly valve.
Background
The valve body of the existing butterfly valve is a through structure, specifically as shown in fig. 1 and fig. 2, the butterfly valve comprises a valve body 1, a sealing layer 2, a rotating shaft 4, a valve plate 3 and a rotating handle 5, the inside of the valve body 1 is the through structure, the aperture of the valve body is unchanged, the thickness of the valve plate 3 is also unchanged, and the butterfly valve has the following disadvantages when in use:
1. because the valve plate 3 and the rotating shaft 4 can provide certain resistance to the flowing fluid, the flow rate of the fluid can be reduced, and the using effect of the butterfly valve is influenced.
2. Due to the existence of the rotating shaft 4, the valve plate 3 has to have larger thickness, and due to the thicker valve plate and the thickening deformation in the middle part, when fluid passes through, the thickness of the valve plate easily causes fluid vortex, so that the fluid has larger resistance, and the flow rate of the fluid is reduced.
Disclosure of Invention
The purpose of the invention is as follows: in order to overcome the defects in the prior art, a novel low-resistance butterfly valve is provided.
The technical scheme is as follows: in order to achieve the above object, the utility model provides a novel low resistance butterfly valve, including valve body, sealing layer, pivot and valve plate, the aperture of valve body is followed both sides kneck and is located the expansion towards the valve plate respectively, forms the expansion portion in valve plate department, the valve plate is the fusiformis structure.
Further, the length of the expansion part is equal to the diameter of the valve plate.
Furthermore, the front and back surfaces of the valve plate are uniformly thinned towards two sides respectively by taking the rotating shaft as a reference.
Furthermore, the front surface of the valve plate is uniformly thinned towards two sides by taking the rotating shaft as a reference, and the back surface of the valve plate is of a plane structure.
Further, the sealing layer is made of hard sealing materials, such as pressure-resistant asbestos rubber, annealed aluminum, mild steel and the like.
The interface and the expansion part of the valve body adopt smooth transition, thereby reducing the vortex generated by the fluid at the path change part of the valve body and further reducing the resistance of the fluid at the low-resistance butterfly valve.
The design principle of the utility model is that:
1. the valve body is designed into a structure which is enlarged from two ends to the middle, the drift diameter in the valve body, particularly the valve plate area is enlarged, so that the effective flow section of fluid passing through the valve plate is enlarged, the flow area of the valve body is larger than that of the interface, the flow speed of the fluid passing through the valve plate is not reduced, and the internal resistance of the valve body is reduced.
2. The valve plate is designed into a shuttle-shaped structure, the middle of the valve plate is thick, and the valve plate becomes thinner gradually towards the overflowing edge, and the edge of the valve plate is thin and is evenly transited to the thick part in the middle, so that the generation of vortex can be greatly reduced when fluid flows through the valve plate, and the resistance of the fluid in the valve body is also reduced.
Has the advantages that: compared with the prior art, the utility model, through the mode of enlarging the valve body latus rectum and changing the valve plate structure, can reduce the resistance of fluid in the valve body effectively, promoted the result of use of butterfly valve, possessed splendid application prospect.

Detailed Description
The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.
Example 1:
as shown in fig. 3 and 4, the utility model provides a novel low resistance butterfly valve, including valve body 1, sealing layer, pivot 4 and valve plate 3, the aperture of valve body 1 is from the even expansion of both sides kneck respectively towards middle valve plate 3 department, forms the expansion portion in valve plate 3 department, and the length of expansion portion equals or is greater than the diameter of valve plate 3, and valve plate 3 is the fusiformis structure, and the positive and negative of valve plate 3 all uses pivot 4 to do not face both sides uniform attenuation as the benchmark.
In the embodiment, when the butterfly valve is in an open state, when fluid passes through the expansion part, although a part of the flow area is occupied due to the existence of the valve plate 3 and the rotating shaft 4, the flow area of the expansion part is still larger than the interface of the valve body 1 as a whole, so that the flow velocity of the fluid is not reduced, that is, the resistance to the fluid in the valve body 1 is reduced; meanwhile, when the fluid passes through the valve plate 3 in the open state, because the edge of the valve plate 3 is thin and is uniformly transited to the middle thick part, the condition that the fluid generates vortex when passing through the valve plate 3 is greatly reduced, and the resistance to the fluid in the valve body 1 is further reduced.
Example 2:
as shown in fig. 3 and 5, the utility model provides a novel low resistance butterfly valve, including valve body 1, sealing layer, pivot 4 and valve plate 3, the aperture of valve body 1 is from the even expansion of both sides kneck respectively towards middle valve plate 3 department, forms the expansion portion in valve plate 3 department, and the length of expansion portion equals the diameter of valve plate 3, and valve plate 3 is the fusiformis structure, and the front of valve plate 3 uses pivot 4 as the benchmark towards the even attenuation of both sides.
In the embodiment, when the butterfly valve is in an open state, when fluid passes through the expansion part, although a part of the flow area is occupied due to the existence of the valve plate 3 and the rotating shaft 4, the flow area of the expansion part is still larger than the interface of the valve body 1 as a whole, so that the flow velocity of the fluid is not reduced, that is, the resistance to the fluid in the valve body 1 is reduced; meanwhile, when the fluid passes through the valve plate 3 in the open state, because the edge of the valve plate 3 is thin and is uniformly transited to the middle thick part, the condition that the fluid generates vortex when passing through the valve plate 3 is greatly reduced, and the resistance to the fluid in the valve body 1 is further reduced.
