Description
Technical field
The utility model belongs to valve technology field, specifically a kind of connection of butterfly valve and executing agency at cofferdam
Structure.
Background technique
Butterfly valve is due to being valve with fastest developing speed in recent ten years with good flow regulating function and closing sealing characteristics
One of door kind.The use scope of butterfly valve is very extensive.Its kind used and quantity still are continuing to expand, and to high temperature, height
Pressure, heavy caliber, high leakproofness, long-life, excellent control characteristic and the multi-functional development of a valve.Its reliability and other property
Energy index reaches higher level.Existing butterfly valve is generally adopted by valve rod and the connecting shaft of executing agency passes through connector sleeve or folder
The connection type of block, although this mounting means reserves biggish installation space around pipeline, when it is mounted on underground piping
In when these spaces and be unsatisfactory for construction demand.When valve body is integrally buried under the ground, in order to facilitate the operation of the switch of valve, need
Executing agency is placed on the place convenient for worker operation.And the connection of existing butterfly valve and executing agency, this special
Demand is unable to satisfy under occasion.
Summary of the invention
The purpose of the utility model is to provide a kind of connection structure of butterfly valve and executing agency at cofferdam, by extended
Connection type can satisfy to be used under the occasion for needing cofferdam, makes executing agency beyond well head, and facilitating worker operation
Place is connected with valve body.
According to the technical solution of the utility model, the connection structure of the butterfly valve and executing agency at cofferdam, including valve
Body, valve rod and executing agency, the valve rod are mounted in valve body using bearing, and valve plate is connected on valve rod, the body top
Bracket is installed in Flange Plane, extension frame is connected between bracket and executing agency, extends and is equipped with connecting shaft, the company in frame
The lower end of spindle is connected using fixture block with valve rod, and the upper end of connecting shaft connects executing agency.
Further, the diameter that the middle part of the connecting shaft is located at the part extended in frame is greater than the diameter of upper and lower ends.
Further, there are gaps between the connecting shaft and extension frame.
Further, the extension frame is formed using steel-pipe welding, and the both ends for extending frame are equipped with flange face.
Further, the connector is fixture block.
The utility model has the beneficial effects that: greatly prolonging the connection distance of executing agency and valve body, facilitate work
People's operation；Extend frame and uses steel-pipe welding, it is various functional；Connecting shaft using intermediate overstriking structure design, make it is capable
It will not excessively be concentrated in conduction at a distance, connecting shaft is prevented to be deformed；Extend between frame and connecting shaft that there are between suitable
Gap, it is ensured that the inclination on position will not occur during assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols: 1- valve rod, 2- valve body, 3- bracket, 4- connecting shaft, 5- extend frame, 6- executing agency, 7- connection
Part.
Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: the connection structure of butterfly valve and executing agency at cofferdam, including valve body 2, valve rod 1 and executing agency 6,
Valve rod 1 is mounted in valve body 2 using bearing, is connected by pin or key with valve plate on valve rod 1.Flange Plane at 2 top of valve body
Upper to be equipped with bracket 3 by bolt, the lower end of frame 5 is same is bolted for the upper end of bracket 3 and extension, extension frame 5 it is upper
End connection executing agency 6.It is equipped with connecting shaft 4 in the inside for extending frame 5, the lower end of connecting shaft 4, which is stretched out, extends frame 5 in bracket 3
Inner utilization connector 7 is connected with valve rod 1, and the upper end of connecting shaft 4, which is stretched out, extends the connection of frame 5 executing agency 6.Connector 7 can be with
Using fixture block.
It is formed specifically, extending frame 5 using steel-pipe welding, functional, the both ends for extending frame 5 are equipped with flange face, are convenient for
Connection.The diameter that the middle part of connecting shaft 4 is located at the part extended in frame 5 is greater than diameter of the upper and lower ends for the part of connection,
Make it is capable will not excessively be concentrated in remote conduction, prevent connecting shaft to be deformed.In connecting shaft 4 and extend between frame 5
There are suitable gaps, it is ensured that the inclination on position will not occur during assembly.
Working principle: butterfly valve drives valve plate rotation to open and close simultaneously by rotary valve rod, logical in butterfly valve body cylinder
In road, disk valve plate is rotated around axis；Executing agency 6 drives valve plate to open or close by connecting shaft 4 with ovable valve stem 1
Valve.Under this special occasion in cofferdam, which is enable by couple-extended shaft and the connecting bushing for extending frame formation
Normal use.
