Abstract
The utility model relates to a kind of handle tetrafluoro butterfly valves, including valve body, valve plate, valve rod and handle, the fluid channel of lateral direction penetrating is formed in valve body, longitudinal through-hole is formed on the corresponding valve body in portion in the fluid passage and valve rod is coated in through-hole, valve plate is installed in the fluid channel of valve rod lower end, valve rod upper end stretches out valve body and is equipped with handle, semiorbicular input retaining ring is formed in the valve interior wall side of fluid input, semiorbicular output retaining ring is formed in the valve interior wall other side of fluid exit, when fluid channel is truncated in valve plate, input the input terminal of retaining ring sealing cooperation valve plate two sides, export the output end of retaining ring sealing cooperation valve plate；Middle part is longitudinal in the valve body of input terminal is formed with an arc vertical plate, valve rod installation position periphery of the sealing cooperation in the middle part of valve plate.The utility model is using tetrafluoro as valve body material, and total quality is light, and most of components can be integrally formed, and reduces assembly, valve trafficability performance is good, and the installation of valve part is simple.
Description
Technical field
The utility model belongs to valve field, especially a kind of handle tetrafluoro butterfly valve.
Background technique
Butterfly valve is that valve application is relatively extensive a kind of, currently, the basic structure of butterfly valve is all in valve body inner seat, valve body
Upper radially installed valve rod installs valve plate on the intracorporal valve rod of valve, and valve rod drives valve plate rotation, to open and close the stream in valve seat
Road.Tetrafluoride material good flowing properties, and lighter weight can be used compression or squeeze out machine-shaping, are widely used as resistance to height
Temperature, resistant material, insulating materials, anti-stick coating etc..
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of design rationally, structure it is simple,
Handle tetrafluoro butterfly valve easy to operate, with long service life.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of handle tetrafluoro butterfly valve, including valve body, valve plate, valve rod and handle, are formed with the stream of lateral direction penetrating in valve body
Body channel is formed with longitudinal through-hole on the corresponding valve body in portion in the fluid passage and is coated with valve rod in through-hole, valve rod lower end
Fluid channel in valve plate is installed, valve rod upper end stretches out valve body and is simultaneously equipped with handle, it is characterised in that: in fluid input
Valve interior wall side is formed with semiorbicular input retaining ring, is formed with semiorbicular output in the valve interior wall other side of fluid exit
Retaining ring, when fluid channel is truncated in valve plate, the input terminal of input retaining ring sealing cooperation valve plate two sides, output retaining ring sealing cooperates valve
The output end of plate；Middle part is longitudinal in the valve body of input terminal is formed with an arc vertical plate, valve rod peace of the sealing cooperation in the middle part of valve plate
Fill position periphery.
It directly installs and is fixed in valve plate moreover, stem lower portion is made as regular hexagon prism.
Moreover, being set with metal outer outside valve body.
The advantages and positive effects of the utility model are as follows:
The utility model is using tetrafluoro as valve body material, and total quality is light, and most of components can be integrally formed,
Assembly is reduced, valve trafficability performance is good, and the installation of valve part is simple.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model；
Fig. 2 is A-A in Fig. 1 to sectional view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of handle tetrafluoro butterfly valve, including valve body 2, valve plate 4, valve rod 7 and handle 1, are formed with lateral direction penetrating in valve body
Fluid channel, be formed with longitudinal through-hole on the corresponding valve body in portion in the fluid passage and be coated with valve rod, valve rod in through-hole
Valve plate is installed, valve rod upper end stretches out valve body and is equipped with handle, and control handle being capable of driving stem in the fluid channel of lower end
Rotation, so that valve plate rotation be driven to open or close valve；
In order to guarantee structural strength, metal outer 3 is set with outside valve body.
Referring to shown in attached drawing 2, stem lower portion is made as regular hexagon prism and directly installs to be fixed in valve plate, without screw etc.
Fixing piece simplifies structure and guarantees sealing.
It is formed with semiorbicular input retaining ring 6 in the valve interior wall side of fluid input, in the valve body of fluid exit
The wall other side is formed with semiorbicular output retaining ring 8, when fluid channel is truncated in valve plate, input retaining ring sealing cooperation valve plate two sides
Input terminal, the output end of output retaining ring sealing cooperation valve plate, the present embodiment valve plate one-directional rotation；
In order to further ensure leakproofness, middle part is longitudinal in the valve body of input terminal is formed with an arc vertical plate 5, sealing cooperation
Valve rod installation position periphery in the middle part of valve plate, auxiliary input retaining ring.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
