The utility model discloses valve rod and cylinder link nut fluting, belong to high-pressure water descaling valve apparatus field, including valve rod, the valve rod is connected with cylinder rod, the valve rod is connected with valve stem nut, the cylinder rod is connected with cylinder nut, is provided with adpting flange one and adpting flange two on the outside of the valve stem nut and the cylinder nut, the adpting flange one and the adpting flange two pass through tools for bolts ' pretension.The utility model can carry out pretension to screw thread, prevent its rotation, so as to improve the degree of stability of screw thread, avoid the valve rod and the cylinder rod from rocking, improve the service life of the valve rod and the cylinder rod, reduce production cost.
Description
Technical field
The utility model belongs to high-pressure water descaling valve apparatus field, and in particular to valve rod and cylinder link nut fluting.
Background technology
In the daily steel processing operation process of steel mill, steel surface can form one layer of oxide skin, must before billet rolling
The iron scale on surface must be removed, high-pressure water descaling valve is exactly that a kind of elimination for being commonly used in steel surface iron scale is set
Standby, in the presence of nozzle, water under high pressure forms a fan-shaped water beam with great impact power, billet surface is ejected into, at this
In the presence of individual high pressure sector Water projectile, iron scale experienced it is cut, chilling shrink, with matrix mother metal peel off, and by
The process for leaving billet surface is washed into, it is clean so as to which iron scale be removed.But the water under high pressure used at present in steel mill removes
Squama valve valve rod is connected with cylinder using direct-connected, and this connected mode is because the power that it is transmitted is bigger, not no good firmly beforehand meanses,
Therefore the loosening of screw thread is easily caused in use, and long-term use can damage to the screw thread of valve rod and cylinder.
Utility model content
The purpose of this utility model is that to solve the above problems and provides valve rod and cylinder link nut fluting.
The utility model is achieved through the following technical solutions above-mentioned purpose：
Valve rod and cylinder link nut fluting, including valve rod, the valve rod are connected with cylinder rod, the valve rod and valve rod
Nut is connected, and the cylinder rod is connected with cylinder nut, the company of being provided with the outside of the valve stem nut and the cylinder nut
Acting flange one and adpting flange two, the adpting flange one and the adpting flange two pass through tools for bolts ' pretension.
In said structure, compared with the direct-connected high-pressure water descaling valve equipment of tradition, the utility model increases the valve rod spiral shell
Female and described cylinder nut, an inclined-plane is processed in nut root, a 3mm or so opening is processed in the radial direction of nut, this
It is open as pass through openings, the fluting for making nut by the inclined-plane between nut carries out pretension to screw thread, so as to fix this practicality newly
Type.
In order to further improve performance of the present utility model, the valve stem nut connects with the valve rod, the gas
Cylinder rod connects with the cylinder nut.
In order to further improve performance of the present utility model, the adpting flange one and the adpting flange two pass through
The bolt carries out pretension.
In order to further improve performance of the present utility model, set between the valve stem nut and the cylinder nut
There are an openings.
In order to further improve performance of the present utility model, the valve rod is fixedly connected with the cylinder rod.
Beneficial effect is：The utility model can carry out pretension to screw thread, its rotation be prevented, so as to improve the steady of screw thread
Determine degree, avoid the valve rod and the cylinder rod from rocking, improve the service life of the valve rod and the cylinder rod, reduce life
Produce cost.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-Figure 2, valve rod and cylinder link nut fluting, including valve rod 1, valve rod 1 are connected with cylinder rod 2,
Valve rod 1 is connected with valve stem nut 3, and cylinder rod 2 is connected with cylinder nut 4, and valve stem nut 3 and the outside of cylinder nut 4 are installed
There are adpting flange 1 and adpting flange 26, adpting flange 1 and adpting flange 26 pass through the pretension of bolt 7.
In said structure, compared with the direct-connected high-pressure water descaling valve equipment of tradition, the utility model increase He of valve stem nut 3
Cylinder nut 4, an inclined-plane is processed in nut root, process a 3mm or so opening in the radial direction of nut, this opening is to pass through
Mouth is opened up, the fluting for making nut by the inclined-plane between nut carries out pretension to screw thread, so as to fixed the utility model.
In order to further improve performance of the present utility model, valve stem nut 3 and valve rod 1 connect, cylinder rod 2 and cylinder
Nut 4 connects, and valve stem nut 3 can be used for being fixedly connected with valve rod 1 and cylinder rod 2 with cylinder nut 4, and it is fixed, fixed to be provided for it
Bit function, adpting flange 1 and adpting flange 26 carry out pretension by bolt 7, and bolt 7 can be fixedly connected with flange 1 and connect
The position of acting flange 26, an openings are provided between valve stem nut 3 and cylinder nut 4, are easy to assemble, valve rod 1 and cylinder
Bar 2 is fixedly connected, and can be used for being driven.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
