Abstract
The utility model relates to a manual butterfly valve which comprises a valve body, a handle, a valve core, a valve rod and a transposition gear. The valve body is in a circular disc shape. A nylon ring is arranged in a middle hole in the valve. The valve core capable of rotating is arranged in the middle of the nylon ring and is connected with the valve rod vertically installed in the valve body. The transposition gear is fixedly arranged on an upper end face of the valve body through a screw. The valve rod penetrates through the transposition gear and is connected with the handle arranged above through a connecting rotary rod. A clutch hand rod is connected with the lower end of the handle through a rotary shaft. An abutting pin is vertically installed in the inner side of the middle of the clutch handle rod. The abutting pin is connected with the middle portion of the handle through a spring. A rack meshed with the transposition gear is arranged at the front end of the clutch hand rod. The manual butterfly valve is simple in structure, beautiful in appearance, light in weight, good in anti-corrosion performance and accurate in flow control.
Description
Technical field
The utility model relates to a kind of butterfly valve, particularly a kind of Hand-operated butterfly valve.
Background technique
Present general Hand-operated butterfly valve all is to adopt cast iron or cast steel to make valve body and spool, but the application of butterfly valve is more and more wider now, in fields such as plumbing drain system, salt solution and seawater pipe, soda acid and chemical solution systems application is arranged, in use the dielectric corrosion that betransported easily of the butterfly valve made of metallic material reduces working life.And the butterfly valve quality of cast iron or cast steel manufacturing is large, and installation and maintenance are got up also inconvenient.To rotate minimum angle be 15 ° to the spool of existing Hand-operated butterfly valve at every turn in addition, but often need in actual use to rotate the angle fine setting flow less than 15 °.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of Hand-operated butterfly valve, and is simple in structure, beautiful shape, and quality is light, and Corrosion Protection is good, and flow control is more accurate.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Hand-operated butterfly valve is provided, comprise valve body, handle, spool, valve rod and transposition gear, described valve body becomes discoid, in the circular hole in the middle of it nylon ring is installed, the centre of described nylon ring is equipped with rotating spool, described spool links to each other with the valve rod that vertically is installed in valve inner, be mounted by means of screws with the transposition gear on the upper-end surface of described valve body, described valve rod passes the transposition gear and links to each other with the handle of top by connecting bull stick, the lower end of described handle is connected with the clutch hand lever by rotating shaft, the middle inboard, upright of described clutch hand lever is equipped with ejector pin, described ejector pin links to each other with the middle part of handle by spring, and the front end of described clutch hand lever is furnished with the tooth bar that is meshed with the transposition gear.
The between cog minute of angle of described transposition gear is 5 °.
Described valve body and spool are made by UPVC plastics or CPVC plastics or PPH plastics or PVDF plastics or FRPP plastics.
Beneficial effect
The utility model relates to a kind of hand-operated pneumatic butterfly valve, simple in structure, utilize the PVC highstrenghtpiston to make valve body and spool, beautiful shape, lightweight, corrosion resistance is strong, wear-resistant, be convenient to installation and removal, can be applied in a plurality of fields such as plumbing drain system, salt solution and seawater pipe, soda acid and chemical solution system, the employing scale division value is 5 ° gear, makes butterfly valve finer and smoother in the control of flow, more accurate.
