Description
Technical field
The present invention relates to control valve fields, in particular it relates to which a kind of valve rod of globe valve is connected with flap
Structure and globe valve configured with the connection structure.
Background technology
Globe valve(Include mainly shut-off valve, bellows stop valve, single-seat adjusting valve, sleeve adjusting valve etc.)It is a kind of use
Prodigious valve is measured, structure type is also very much, is adapted to the requirement of different operating modes.Globe valve can be used for controlling empty gas and water, steaming
The flowing of the various types fluids such as vapour, various Korrosionsmediums, 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 there are one sealing surfaces for generally spherical valve, thus anufacturability is relatively good, and just
In repair.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 is a small amount of free gap so that valve is more effectively sealed to make up cumulative errors simultaneously.Spherical shape in the prior art
Valve, the connection of generally use steel ball, anti-shear ability are poor.
Invention content
Technical problem to be solved by the invention is to provide a kind of valve rods of globe valve and flap connection structure, can carry
The anti-shear ability of high structure, to improve the reliability of globe valve.
In order to solve the above-mentioned technical problem, present invention employs following technical solutions:A kind of valve rod and flap of globe valve
Connection structure, including flap, valve rod, roller and plug open up blind hole on the flap, and the valve rod is connected to the blind hole
Interior, the flap has opposite periphery with the valve rod, and first annular slot and second are opened up respectively on each periphery
Annular groove is further opened with filling aperture on the flap, and multiple rollers are filling in described first annular by the filling aperture
In the cavity that slot is collectively formed with second annular groove, the plug is plugged in the filling aperture.
Preferably, the end of the blind hole is further opened with groove, and thrust pad is provided in the groove.
Preferably, the thickness of the first annular slot and the thickness of second annular groove are 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, invention additionally discloses a kind of globe valve, including valve body and valve deck, the globe valve further include as any one of aforementioned
The valve rod and flap connection structure of the globe valve.
Compared with prior art, the beneficial effects of the present invention are:It is filling between valve rod and flap using roller, it will show
There is the point contact in technology to be extended to line contact, improve the anti-shear ability of structure, to finally improve reliability of structure.

Specific implementation mode
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, but not as the limit to the present invention
It is fixed.
Referring to Fig.1 shown in-Fig. 3, the valve rod and flap connection structure of globe valve of the invention, including flap 1, valve rod 5, rolling
Column 3 and plug 4.
As shown in the figure, blind hole is opened up on flap 1(It is 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(It is not indicated in figure).Be further opened 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 and is configured for one week, 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 ease of adjusting the relative position of flap 1 and valve rod 5, formed so as to adjust first annular slot and the second annular groove
The end of the height of cavity, blind hole is further opened with groove(It is not indicated in figure), thrust pad 2 is provided 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, thereby using
The roller of low dimensional.
Cooperation for ease of the installation of roller 3 and 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 present invention, filling aperture 6 is rectangular opening, is arranged in the side of flap 1.Preferably, plug 4 is rectangle, plug 4
It is fixedly welded in filling aperture 6.
The globe valve of the present invention, including valve body, valve deck and valve rod above-mentioned 5 and 1 connection structure of flap.Valve body and valve deck
Deng, different selections can be carried out according to different valves, but the part is not the main improvement of the present invention, therefore no longer extension explanation.
A kind of stronger valve rod of bearing capacity of present invention offer and flap connection structure.Total processing technology is without spy
Different to require, cost will not dramatically increase.Main realization rate is to substitute steel ball by roller 3, and point contact is extended to line contact,
The anti-shear ability for improving structure, finally improves reliability of structure.
Above example is only exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can within the spirit and scope of the present invention make respectively the present invention
Kind modification or equivalent replacement, this modification or equivalent replacement also should be regarded as being within the scope of the present invention.
