Abstract
The utility model relates to valve technology fields.Using the butterfly valve of curved surface cavity, including valve body, butterfly plate and valve rod, butterfly plate is round butterfly plate, valve body includes an inner cavity, butterfly plate is rotatably installed in the lumen by valve rod, the longitudinal section of the wall of inner cavity is in arc-shaped, and diameter of a circle where circular arc is greater than the diameter of butterfly plate, and the wall of inner cavity is the central axis one week curved wall that is formed of the circular arc around inner cavity；The cross section of inner cavity is circle, and inner cavity intermediate cross-section diameter of a circle is maximum, and two end section diameter of a circles are minimum.The inner cavity of butterfly valve is optimized for curved by the utility model, is made the power for directly acting perpendicularly to butterfly plate originally, is changed direction, form vortex at butterfly plate, to reduce water to the active force of butterfly plate, facilitate opening and closing.The arc diameter of inner cavity longitudinal section is greater than the diameter of butterfly plate, makes butterfly plate will not be stuck in rotation.
Description
Technical field
The utility model relates to valve technology field more particularly to a kind of butterfly valves.
Background technique
Butterfly valve is a kind of simple regulating valve of structure, the switch control for low pressure pipeline medium.The inner cavity of general butterfly valve
It is tube bundle shape, the pressure of water flow acts directly on butterfly plate, and butterfly plate is made to be not easy to switch.
Utility model content
The purpose of this utility model is to provide a kind of butterfly valves using curved surface cavity, to solve the above problems.
Using the butterfly valve of curved surface cavity, including valve body, butterfly plate and valve rod, the butterfly plate is round butterfly plate, the valve body packet
An inner cavity is included, the butterfly plate is rotatably mounted in the inner cavity by the valve rod, which is characterized in that the wall of the inner cavity
Longitudinal section be in arc-shaped, diameter of a circle where circular arc is greater than the diameter of the butterfly plate, and the wall of the inner cavity is circular arc around institute
State the one week curved wall formed in central axes of inner cavity；
The cross section of the inner cavity is circle, and inner cavity intermediate cross-section diameter of a circle is maximum, and two end sections are justified straight
Diameter is minimum.
The inner cavity of butterfly valve is optimized for curved by the utility model, is made the power for directly acting perpendicularly to butterfly plate originally, is changed
Direction forms vortex at butterfly plate, to reduce water to the active force of butterfly plate, facilitates opening and closing.The arc diameter of inner cavity longitudinal section
Greater than the diameter of butterfly plate, make butterfly plate will not be stuck in rotation.
The butterfly plate sets radial drainage groove close to edge, and the drainage groove is got over closer to the edge of the butterfly plate
It is deep.Drainage groove can guide water flow, further decrease water to the active force of butterfly plate.
The inner cavity is equipped with ceramic-seal ring, and the edge of the butterfly plate is equipped with ceramic seal circle.Leakage when butterfly plate being prevented to be closed
Water.
As a preferred embodiment, the centre of the ceramic-seal ring is equipped with teflon seal ring.Polytetrafluoroethylene (PTFE)
Material lubricity is preferable, and butterfly plate is facilitated to open and close.
The both ends of the valve body are equipped with connector pipeline, and the internal diameter of connector pipeline is identical as the minimum diameter of the inner cavity.Make
Inner wall of the pipe is connected with inner cavity interior walls be smooth.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model；
Fig. 2 is another structural schematic diagram of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to Fig.1, using the butterfly valve of curved surface cavity, including valve body 1, butterfly plate 2 and valve rod 3, butterfly plate 2 is round butterfly plate, valve
Body 1 includes an inner cavity 4, and butterfly plate 2 is rotatably mounted in inner cavity 4 by valve rod 3, and the longitudinal section of the wall of inner cavity 4 is in arc-shaped,
And diameter of a circle where circular arc is greater than the diameter of butterfly plate, the wall of inner cavity 4 is circular arc being formed for central axis one week around inner cavity 4
Curved wall；The cross section of inner cavity 4 is circle, and 4 intermediate cross-section diameter of a circle of inner cavity is maximum, and two end section diameter of a circles are minimum.
The inner cavity 4 of butterfly valve is optimized for curved by the utility model, changes the power for directly acting perpendicularly to butterfly plate 2 originally
Direction forms vortex at butterfly plate 2, reduces water to the active force of butterfly plate 2, facilitates opening and closing.The arc diameter of 4 longitudinal section of inner cavity is big
In the diameter of butterfly plate 2, make butterfly plate 2 will not be stuck in rotation.
Butterfly plate 2 sets radial drainage groove 5 close to edge, and drainage groove 5 is deeper closer to the edge of butterfly plate 2.Draining
Groove 5 can guide water flow, further decrease water to the active force of butterfly plate 2.Inner cavity 4 is equipped with ceramic-seal ring 6, the side of butterfly plate 2
Edge is equipped with ceramic seal circle 7.Leak when butterfly plate 2 being prevented to be closed.As a preferred embodiment, the centre of ceramic-seal ring 6 is equipped with
Teflon seal ring.Polytetrafluoroethylene material lubricity is preferable, and butterfly plate 2 is facilitated to open and close.The both ends of valve body 1 are equipped with junction block
The internal diameter in road 8, connector pipeline 8 is identical as the minimum diameter of inner cavity 4.Connect inner wall of the pipe with inner cavity interior walls be smooth.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
