Abstract
The utility model discloses a butterfly valve filler compensation device which comprises a valve body, a valve shaft, filler, a filler gland, a bolt and a filler pressing plate. The butterfly valve filler compensation device is characterized in that an elastic device is arranged between the bolt and the filler pressing plate. According to the butterfly valve filler compensation device, in the case of filler loss, the filler and the valve shaft are in close contact under the effect of a butterfly spring, and a medium is prevented from leaking from a space between the filler and the valve shaft; and moreover, the device has a simple and practical structure and high replaceability, and avoids the trouble of manual operation.
Description
Technical field
The utility model belongs in a kind of industry valve and uses device, specifically is a kind of filler automatic compensator that the automation pipe-line system is gone up in industry that is used for.
Background technique
Use the many of automatic system in now a lot of industry, and the parts that the use right and wrong of valve are usually seen in this system, and be very crucial parts, in practice, play irreplaceable effect.But original valve mechanism is because reasons in structure in use for some time, because factors such as wearing and tearing have ducted medium and spill through the slit between valve shaft and the filler, causes the loss of filler.Thereby make filler follow the gap has been arranged between the valve shaft,, taked at the scene constantly to use artificial fastening nut, it has been exerted pressure, made Gland constantly compress filler in order to remedy the gap between them.Bring what consequence like this? Need manual work constantly it to be tightened exactly, cause the waste of manpower and the waste of filler.
Summary of the invention
The purpose of the utility model just provides a kind of butterfly valve filler compensation device; Solve because filler place dielectric leakage needs artificial problem of constantly nut being exerted pressure; The design's structure has between abundant maintenance filler and the valve shaft and closely contacts; The assurance medium can not avoided numerous and diverse thing of manpower fastening nut from the slot leakage between filler and the valve shaft.
A kind of butterfly valve filler compensation device of the utility model comprises valve shaft, filler, Gland, bolt and hold-down grid, it is characterized in that: between said bolt and hold-down grid, be provided with elastic device.Through elastic device directly being set at bolt and hold-down grid, to have avoided when filler and valve shaft are gapped, medium spills with the gap; Worried thing with artificial fastening nut; Elastic device is because its distinctive elasticity when the gap occurring, is understood the compressible filler gland automatically; Guaranteeing tight contact the between Gland and the filler, can not be that filler is loosening and spill.
Further, said bolt is provided with nut, is provided with T font lining between said nut and the elastic device.T font lining be set mainly be for convex shoulder one end that utilizes T font lining spacing to elastic device.
Further, said elastic device is a butterfly spring.Disk spring material is prone to look for, and changes easily, and commutativity is strong.
Further, said elastic device is a stiffness spring.Disk spring material is prone to look for, and changes easily, and commutativity is strong.
The beneficial effect of the utility model is between hold-down grid and nut, one group of butterfly spring has been installed, like this; When filler stream is missed the season; Because the effect of butterfly spring, make between filler and the valve shaft closely contact, guaranteed that medium can be from filler and valve shaft leakage; Simple in structure, practical, commutativity is strong; Avoided manually-operated worry.

Embodiment
As shown in the figure, the butterfly valve filler automatic compensator of the utility model is arranged on the valve shaft 1 on the valve, is provided with filler 3 at the cylindrical of valve shaft, and the upper end of filler 3 is Glands 2, and filler 3 is compressed; The upper end of Gland 2 nestles up hold-down grid 4; And bolt 7 passes through the bolt hole that is provided with on the hold-down grid 4 hold-down grid 4 and Gland 2; Filler 3 grades are fixed on the valve body, are arranged on nut 5 on the bolt 7 to its time pressure, are used for hold-down grid 4 is exerted pressure.Between nut 5 and hold-down grid 4, be provided with butterfly spring 6, also be provided with the lining 8 of T font between said butterfly spring 6 and the nut 5, butterfly spring 6 one ends are resisted against on the convex shoulder of T font lining 8, and the other end is resisted against on the hold-down grid.Under the situation of nut screwing clamping, hold-down grid is exerted pressure through lining and butterfly spring.When spilling because of the slit between filler and the valve shaft, because the disappearance of filler, filler can become flexible; In case it is loosening; Butterfly spring is given hold-down grid because the elastic force reason can apply power, thereby passes to Gland then with filling compaction, prevents that the slit between filler and the valve shaft from increasing.
Explanation is at last; Above instance only is used to explain the technological scheme of the utility model and is unrestricted; Although the utility model is specified with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that can to the technological scheme of the utility model make amendment or be equal to replacement; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
