Specific embodiment
As shown in Fig. 1,2,4, teletransmission valve position indicator, including the follow-up unit 2 being fixedly connected with valve rod 1, steel wire
One end of rope 3 is fixedly connected with follow-up unit 2, and when the valve rod 1 of valve makees angle stroke motion, the other end card of steel wire rope 3 sets
Fix with disk 4 in the gathering sill 11 of disk 4 and by knot, the central shaft 5 of disk 4 is arranged on base plate 8, central shaft 5
Can rotate around base plate 8, the perisporium of steel wire rope 3 abuts cooperation with the inwall of gathering sill 11, steel wire rope 3 drives disk 4 together
Rotate, pointer 6 is installed with the center of disk 4, direction board 7 is installed on base plate 8, in the process that disk 4 is rotated
In, pointer 6 is swung in the range of direction board 7, and the end of steel wire rope 3 is fixedly connected with elastic device 10, and elastic device 10 is fixed
On building, the interlude of steel wire rope 3 changes transmission direction by fixed pulley 9；
When the valve rod 1 of valve makees Direct Travel to move, the other end of steel wire rope 3 is fixedly connected with guide pad 13, on base plate 8
Guide rail 12 is fixed with, guide pad 13 is for linear motion along guide rail 12, on guide pad 13, is installed with pointer 6, installed on base plate 8
There is direction board 7, during guide pad 13 is moved, pointer 6 is moved in the range of direction board 7, guide pad 13 and elastic device
10 are fixedly connected, and elastic device 10 is fixed on building, and the interlude of steel wire rope 3 changes transmission direction by fixed pulley 9.
As shown in figure 5, follow-up unit 2 is by being sleeved on valve rod 1 and semicircular ring A16 that fastened by bolt 14 and semicircular ring
B15 is constituted, and the trapezoidal hole 18 of vertical direction is offered in semicircular ring A16, and 18 times mouths of trapezoidal hole are wide suitable for reading little, wide in trapezoidal hole 18
Through hole 17 is provided with mouth section horizontal direction, when the valve rod 1 of valve makees Direct Travel to move, wide opening of the steel wire rope 3 from trapezoidal hole 18
Penetrate, pass from the osculum of trapezoidal hole 18, steel cord ends are equipped with the wide opening section that knot is stuck in trapezoidal hole 18, also can be in trapezoidal hole
In 18 wide opening sections, injection glue is fixed；When the valve rod 1 of valve makees angle stroke motion, width of the steel wire rope 3 from trapezoidal hole 18
Mouth is penetrated, and is passed from through hole 17, and the knot that steel cord ends are equipped with is stuck in the wide opening section of trapezoidal hole 18, when valve rod 1 rotates,
The steel wire rope 3 for passing through hole 17 is wound in the circumferential recess 20 of semicircular ring A16 and semicircular ring B15, steel wire rope（3）Week
Wall abuts cooperation with the inwall of groove 20, and the gathering sill 11 is identical with the diameter of groove 20.
One embodiment of the present invention is, when valve rod 1 makees angle stroke motion, follow-up unit 2 is driven when valve rod 1 rotates
Rotate together, follow-up unit 2 pull steel wire rope 3 around disk 4 11 scrolling of gathering sill, due to gathering sill 11 it is straight with groove 20
Footpath is identical, and the angle that now pointer 6 on disk 4 is turned over is exactly the angle that valve rod 1 is turned over.Elastic device 10 in the process
Accumulation of energy is tightened up, when 1 adverse movement of valve rod, steel wire rope 3 is relaxed, now elastic device 10 starts the energy stored before discharging
Amount, reverse tense wire rope 3, it is ensured that as the angle that the angle that pointer 6 is turned over still is turned over valve rod 1, the quantity of fixed pulley 9 according to
Depending on needs when being embodied as.
When valve rod makees Direct Travel to move, valve rod 1 drives follow-up unit 2 to be lifted together, and follow-up unit 2 pulls steel wire rope 3,
The drive guide pad 13 of steel wire rope 3 is for linear motion along guide rail 12, and the pointer 6 on guide pad 13 is also moved therewith together, pointer 6
The displacement moved on direction board 7 is the displacement that valve rod is lifted, and elastic device 10 is tightened up accumulation of energy in the process, works as valve rod
During 1 adverse movement, steel wire rope 3 is relaxed, and now elastic device 10 starts the energy stored before discharging, reverse tense wire rope
3, it is ensured that still as the displacement of the movement of valve rod 1, the quantity of fixed pulley 9 is according to need when being embodied as the displacement of the movement of pointer 6
Depending on wanting.
As shown in figure 3, another embodiment of the invention is, simply fixed pulley 9 is substituted with flexible sleeve 19, other
As the first embodiment, flexible sleeve 19 flexibly can bend to avoid the barrier in tight quarters structure, from
And transmitting movement, flexible sleeve 19 rolls close winding spring pipe for metal.
