Description
Technical field
The utility model relates to control valve fields, specifically, the utility model relates to a kind of valve rod of globe valve and
Flap connection structure and globe valve configured with the connection structure.
Background technique
Globe valve (mainly including shut-off valve, bellows stop valve, single-seat adjusting valve, sleeve adjusting valve etc.) is a kind of use
Very big valve is measured, structure type is also very much, is adapted to the requirement of different operating conditions.Globe valve can be used for controlling empty gas and water, steaming
The flowing of the various types fluids such as vapour, various corrosive medias, mud, oil product, liquid metal and radiating medium.Globe valve
Valve rod opening travel is relatively short, and Lift is typically only the 1/4 of valve base channel diameter.Frictional force between spherical valve sealing surface
It is small, there is very reliable cutting function.Only one sealing surface of generally spherical valve, thus anufacturability is relatively good, and just
In maintenance.So globe valve has very universal use in industrial system.
General globe valve stem diameter be much smaller than flap diameter, substantially all can separately manufacturing, to save material into
This.But valve rod must drive flap to move together when valve use, so there is the connectivity problem of valve rod and flap.Connection
Preferably there are also a small amount of free gaps simultaneously seals valve more effectively to make up cumulative errors.Spherical shape in the prior art
Valve, generallys use steel ball connection, and anti-shear ability is poor.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of valve rod of globe valve and flap connection structure, energy
The anti-shear ability for enough improving structure, to improve the reliability of globe valve.
In order to solve the above-mentioned technical problem, the utility model adopt the technical scheme that a kind of globe valve valve rod and
Flap connection structure, including flap, valve rod, roller and plug, blind hole is opened up on the flap, and the valve rod is connected to described
In blind hole, the flap and the valve rod have opposite periphery, opened up respectively on each periphery first annular slot with
Second annular groove is also provided with filling aperture on the flap, and multiple rollers are filling in described first by the filling aperture
In the cavity that annular groove and second annular groove are collectively formed, the plug is plugged in the filling aperture.
Preferably, the end of the blind hole is also provided with groove, is provided with thrust pad in the groove.
Preferably, the thickness of the thickness of the first annular slot and second annular groove is the roller
Radius.
Preferably, the filling aperture is rectangular opening.
Preferably, the plug is rectangle.
Preferably, the plug is fixedly welded in the filling aperture.
In addition, a kind of globe valve, including valve body and valve deck is also disclosed in the utility model, which further includes such as aforementioned
The valve rod and flap connection structure of globe valve described in one.
It is compared with prior art, the utility model has the beneficial effects that: filling between valve rod and flap using roller,
Point contact in the prior art is extended to line contact, improves the anti-shear ability of structure, to finally improve the reliable of structure
Property.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as practical to this
Novel restriction.
Referring to Fig.1 shown in-Fig. 3, the valve rod and flap connection structure of the globe valve of the utility model, including flap 1, valve rod
5, roller 3 and plug 4.
As shown in the figure, it is opened up on flap 1 blind hole (not indicated in figure), valve rod 5 is connected in blind hole.Flap 1 and valve rod 5
With opposite periphery, the i.e. lateral surface of the medial surface of flap 1 and valve rod 5, opened up respectively on each periphery first annular
Slot and the second annular groove (not indicated in figure).Be also provided with filling aperture 6 on flap 1, multiple rollers 3 by filling aperture 6 it is filling in
In the cavity that first annular slot and the second annular groove are collectively formed, roller 3 is surrounded on cavity one week and is configured, and plug 4 blocks
In in filling aperture 6.In this way, existing point contact can be extended to line contact, the anti-shear ability of structure is improved, it is final to improve
Reliability of structure.
For the relative position for being conveniently adjusted flap 1 Yu valve rod 5, formed so as to adjust first annular slot and the second annular groove
The height of cavity, the end of blind hole are also provided with groove (not indicating in figure), are provided with thrust pad 2 in groove.In this way, can lead to
The thickness for overregulating thrust pad 2 adjusts the relative position of first annular slot and the second annular groove, so as to optionally change rolling
The height dimension etc. of column 3, such as by the dislocation of first annular slot and the second annular groove, to reduce cavity height, to use
The roller of low dimensional.
For the installation convenient for roller 3 and the cooperation with flap 1 and valve rod 5, the thickness of first annular slot and the second annular
The thickness of slot is the radius of roller 3.
In the utility model, filling aperture 6 is rectangular opening, and the side of flap 1 is arranged in.Preferably, plug 4 is rectangle,
Plug 4 is fixedly welded in filling aperture 6.
The globe valve of the utility model, including valve body, valve deck and valve rod above-mentioned 5 and 1 connection structure of flap.Valve body with
Valve deck etc. can carry out different selections according to different valves, but the part is not the main improvement of the utility model, therefore no longer expand
Open up explanation.
The utility model provides a kind of stronger valve rod of bearing capacity and flap connection structure.Total processing technology does not have
There is particular/special requirement, cost will not dramatically increase.Main realization rate is to substitute steel ball by roller 3, and point contact is extended to line
Contact, improves the anti-shear ability of structure, finally improves reliability of structure.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new
The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new
In the protection scope of type.
