Description
Technical field
The utility model relates to a kind of valve, specifically a kind of valve rod anti-rotational structure.
Background technique
High pressure, big flow are the development trends of hydraulic system and hydraulic components；But high pressure, the liquid stream of big flow are generated
Hydraulic power unfavorable factor is generated to the stability of valve rod state.When hydraulic power refers to that liquid stream flows through valve port, due to flow direction
The change of liquid momentum is caused with the variation of flow velocity, valve rod will receive additional forces.Therefore, in high pressure, big flow hydraulic power
Under the influence of, valve rod state labile in spool bore, so as to cause the unstable of the liquid stream for crossing pasta product by throttling channel.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of anti-rotational knot of valve rod for being adapted to high pressure, big flow
Structure.
The utility model is achieved through the following technical solutions: a kind of valve rod anti-rotational structure, including valve body and is mounted on valve
Valve rod on body；The valve rod outer end is covered with an end cap；2 are provided on the periphery of valve rod outer end with valve rod axle center in center
Symmetrical deep gouge, deep gouge direction are axially parallel in valve rod；It is equipped on the end cap and deep gouge opposite plug cock one by one, oil
The inner end of plug is slidably mounted in corresponding deep gouge.
It is further: the end cap includes a cylindrical section, and the right end of cylinder is fixedly connected with ring flange, the left end of cylinder
It is fixedly connected with hemispherical shell；It is provided on the cylinder and is centrosymmetric the threaded hole of distribution with cylinder axle center, threaded hole
Number is consistent with plug cock number, and the plug cock is mounted in cylinder threaded hole；The ring flange is fixedly connected on valve body.
The left end of the deep gouge is connected to the left side of valve rod.
The inner end of the plug cock is equipped with cylindrical boss；Boss is located in the deep gouge.
The deep gouge number is consistent with plug cock number.
There are gaps between the valve rod and cylinder.
When work, plug cock is mounted on end cap, and end cap cover is then guaranteed the boss sliding of plug cock inner end in valve rod outer end
It is mounted in the deep gouge of valve stem end；Then, end cap is fixedly connected on valve by ring flange；Finally, plug cock is adjusted, so that oily
The boss of plug inner end is against deep gouge bottom, guarantees that the stress of each plug cock is essentially identical.
Compared with prior art, the utility model has the beneficial effects that structure is simple, it is convenient to process and mount, it is at low cost；Oil
Plug can easily be accommodated, easy to operate, and valve rod uniform force, anti-rotational effect is good, and not influence the axial movement of valve rod, can be applied to
High pressure, high-volume hydraulic valve.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
In figure: 1, valve rod；1-1, deep gouge；2, end cap；2-1, hemispherical shell；2-2, cylinder；2-3, ring flange；3, oily
Plug；3-1, boss.
Specific embodiment
It is a specific embodiment of the utility model below, the utility model is described further now in conjunction with attached drawing.
As shown in connection with fig. 1, a kind of valve rod anti-rotational structure, including valve body and the valve rod 1 being mounted on valve body.End cap 2 covers
In 1 left end of valve rod；End cap 2 includes a cylindrical section 2-2, and the right end of cylinder 2-2 is fixedly connected with ring flange 2-3, a left side of cylinder 2-2
End is fixedly connected with hemispherical shell 2-1.There are gaps between valve rod 1 and cylinder 2-2；It is provided on cylinder 2-2 with cylinder 2-2 axis
The heart is centrosymmetric 2 or more threaded holes of distribution, and selection opens up 3 threaded holes in the present embodiment.Ring flange 2-3 is fixed to be connected
It connects on valve body.
It is provided with 3 on the periphery of 1 outer end of valve rod and is centrosymmetric with 1 axle center of valve rod and is distributed deep gouge 1-1, the deep gouge side 1-1
To in 1 axial direction of valve rod, in parallel, the left end of deep gouge 1-1 is connected to the left side of valve rod 1.Plug cock 3 is mounted on cylinder 2-2 threaded hole
In, the inner end of plug cock 3 is equipped with cylindrical boss 3-1；Boss 3-1 is located in deep gouge 1-1.
When assembly:
Plug cock is mounted on end cap, then by end cap cover in valve rod outer end, guarantees that the boss of plug cock inner end is located at valve rod
In the deep gouge of end；The cooperation of plug cock and valve rod deep gouge limits the rotation of valve rod, plays the role of stable valve rod, to make liquid
Pressure valve stability of flow；
Then, end cap is fixedly connected on valve by ring flange；
Guarantee the basic phase of the stress of each plug cock so that the boss of plug cock inner end is against deep gouge bottom finally, adjusting plug cock
Together；Plug cock limits the rotation of valve rod, while not interfering the axial movement of valve rod, and symmetric design makes valve rod stress equalization.
It is simple that above-described embodiment can be seen that the utility model structure, is convenient to process and mount, at low cost；Plug cock is easy to adjust
Section, easy to operate, valve rod uniform force, anti-rotational effect is good, and does not influence the axial movement of valve rod, can be applied to high pressure, big
Flow hydraulic valve.
