Description
Technical field
The utility model relates to a kind of control valve, specifically a kind of PVDF butterfly valve.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, can be used for the switch control of low pressure pipeline medium.Valve
It is various that door can be used for controlling empty gas and water, steam, various corrosive medias, mud, oil product, liquid metal and radiating medium etc.
The flowing of type of fluid.Cutting and throttling action are mainly played on pipeline.Butterfly valve opening and closing element (flap or butterfly plate) is a disk
The butterfly plate of shape rotates in valve body around the axis of its own, to achieve the purpose that opening and closing or adjusting.
Existing butterfly valve structure is all more complicated, ineffective so as to cause its sealing closing, and uses metal material system
It is bad at corrosion resistance.Therefore, those skilled in the art provide a kind of PVDF butterfly valve, to solve to mention in above-mentioned background technique
Out the problem of.
Summary of the invention
The purpose of this utility model is to provide a kind of PVDF butterfly valves, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of PVDF butterfly valve, including valve body and valve seat, the interior middle part of the valve body are provided with valve seat, are equipped in the valve seat
Dish plate, the dish intralamellar part are provided with valve rod, and the valve rod lower end is arranged in valve body, and valve body is run through in the valve rod upper end, and
O-ring is provided between the valve rod top and valve body.
As a further solution of the present invention: left and right sides side is provided with several connecting holes outside the valve body.
The valve body and dish plate are all made of PVDF material and are made as a further solution of the present invention,.
The valve seat and O-ring are all made of EPDM material and are made as a further solution of the present invention,.
It is rotatablely connected between the valve rod and valve body as a further solution of the present invention,.
The valve rod drives the rotation of dish plate as a further solution of the present invention, and dish plate rotates in valve seat.
Compared with prior art, the utility model has the beneficial effects that
The butterfly valve structure is simple, good leak tightness, and valve body and dish plate are all made of PVDF material and are made, and makes its very light in weight, also
With good corrosion resistance, while the butterfly valve driving moment is small, easy to operate, rapid, and there is good flow to adjust function
It can and close sealing characteristics.
Detailed description of the invention
Fig. 1 is a kind of the schematic diagram of the section structure of PVDF butterfly valve.
Fig. 2 is a kind of side schematic view of PVDF butterfly valve.
Fig. 3 is a kind of top view of PVDF butterfly valve.
In figure: 1- valve body, 2- valve seat, 3- dish plate, 4- valve rod, 5-O type circle.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1~3, in the utility model embodiment, a kind of PVDF butterfly valve, including valve body 1 and valve seat 2, the valve
Middle part is provided with valve seat 2 in body 1, dish plate 3 is equipped in the valve seat 2, the dish plate 3 is internally provided with valve rod 4, the valve rod
4 lower ends are arranged in valve body 1, and valve body 1 is run through in 4 upper end of valve rod, and is provided between 4 top of the valve rod and valve body 1 O-shaped
Circle 5.
The 1 outside left and right sides side of valve body is provided with several connecting holes.
The valve body 1 and dish plate 3 are all made of PVDF material and are made.
The valve seat 2 and O-ring 5 are all made of EPDM material and are made.
It is rotatablely connected between the valve rod 4 and valve body 1.
The valve rod 4 drives dish plate 3 to rotate, and dish plate 3 rotates in valve seat 2.
The working principle of the utility model is:
When the utility model is used, rotation valve rod 4, rotates it in valve body 1, it is arranged between valve rod 4 and valve body 1
O-ring 5 can play closed effect, prevent from leaking, and valve rod 4 connect with dish plate 3 and dish plate 3 is driven to rotate in valve seat 2, thus
Make to generate gap between dish plate 3 and valve seat 2, i.e., the butterfly valve is in channel status, and the size of 4 rotational angle of valve rod determines dish plate
The size of 3 rotation angles, i.e., in butterfly valve access medium flow field momentum number, when closing, valve rod 4 is rotated backward, by dish plate 3 and valve
Seat 2 fits, and closing can be realized；
The butterfly valve structure is simple, good leak tightness, and valve body 1 and dish plate 3 are all made of PVDF material and are made, and makes its very light in weight,
Also there is good corrosion resistance, while the butterfly valve driving moment is small, easy to operate, rapid, there is good flow to adjust
Function and closing sealing characteristics.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
