Abstract
The utility model relates to an assembly structure of a valve plate and a valve rod for a butterfly valve. The assembly structure of the valve plate and the valve rod for the butterfly valve comprises a valve plate and a valve rod, and an installation hole matched with the valve rod is formed in the valve plate. And the assembly structure of the valve plate and the valve rod for the butterfly valve is characterized in that the valve plate is detachably connected with the valve rod through a spline. The valve plate and the valve rod adopt a spline connecting structure, and the connecting and the dismantling of the valve plate and the valve rod can be achieved through an inserting motion and a drawing action. Therefore, compared with an existing pin roll connecting structure, the assembly structure of the valve plate and the valve rod for the butterfly valve has the advantages of being convenient to assemble and disassemble, time-saving and labor-saving, and convenient to maintain. In addition, in a dismantling process, rigid knocking is not needed, and therefore parts cannot be damaged.
Description
Technical field
The utility model relates to the flow control valve technical field, particularly a kind of assembly structure for the valve plate on butterfly valve and valve rod.
Background technique
Butterfly valve claims again the reprint valve, is a kind of modulating valve simple in structure, and its switch that is used for the low pressure pipeline medium is controlled.Butterfly valve mainly by valve body, be arranged on valve seat on valve body, be movably arranged on the valve plate in valve seat and be arranged on the valve rod that is connected with valve plate on valve body.Drive valve plate by rotation valve rod and rotate to reach the purpose that opens and closes or regulate.At present, valve plate and valve rod adopt single or multiple bearing pins to be connected.This kind linkage structure exists installation, dismounting inconvenience when reality is used, the problem that wastes time and energy, particularly when dismounting is keeped in repair, need to be by the rigid mode such as knock, bearing pin could be unloaded, this kind dismounting mode can cause component to destroy, and in addition, valve plate is installed also more difficult with again coordinating of valve rod.
Summary of the invention
The utility model provides a kind of assembly structure for the valve plate on butterfly valve and valve rod for solving the technical problem that exists in known technology, this assembly structure has easy accessibility, time saving and energy saving, the characteristics being convenient to keep in repair, also can not cause the destruction of component simultaneously.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of assembly structure for the valve plate on butterfly valve and valve rod comprises valve plate and valve rod, and described valve plate is provided with the mounting hole that matches with valve rod, it is characterized in that: described valve plate is connected the detachable connection of spline with valve rod.
Advantage and the good effect that the utlity model has are:
Valve plate and valve rod adopt the spline joint structure, by a plug-in mounting action and an extraction action, just can realize both connection and fractionation.Therefore this linkage structure is than existing pin shaft connection structure, has easy accessibility, time saving and energy saving, the characteristics being convenient to keep in repair, in addition, due to when the dismounting, do not need to carry out rigid knocking, and therefore can not damage component.
Description of drawings
Fig. 1 is use state reference map of the present utility model.
In figure: 1, valve plate; 2, valve rod.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of assembly structure for the valve plate on butterfly valve and valve rod comprises valve plate 1 and valve rod 2, and described valve plate is provided with the mounting hole that matches with valve rod, and described valve plate is connected the detachable connection of spline with valve rod.Concrete, guaranteeing a section of the mounting hole on valve plate can be made splined hole under the prerequisite that both are fixedly connected with, like this, can reduce difficulty of processing and processing cost.
Valve plate and valve rod adopt the spline joint structure, when mounted, the spline on valve rod and the splined hole on valve plate are aligned, and insert to get final product; When dismounting, do not need hammer action, valve rod is extracted out from valve plate, just can easily achieve both and separate.
The above only is the better example of executing of the present utility model, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all fall into technical scope of the present utility model.
