Abstract
The utility model discloses a stainless steel knitted net reinforced type flexible graphite sealing ring which is composed of a flexible graphite and a stainless steel metal knitted net which are interwoven with each other. The utility model has the advantages of favorable elastic property, high temperature resistance, corrosion resistance, good tightness, low manufacturing cost, etc. and is especially suitable for serving as a sealing material among unparallel flanges with high vibration frequency.
Description
The utility model relates to a kind of flexible graphite sealing material, particularly a kind of stainless steel mesh grid enhancement mode Expanded graphite seal ring.
The graphite packing of generally using at present, packing and stainless steel spirotallic gasket are made sealing material, because graphite self difference of hardness, very easily abrasion, so generally only be used in the sealing of Stuffing box, or make plain cushion between the parallel flange plate, can not be used to vibrate between the frequent not parallel flange plate, and need warm condition poor.
The purpose of this utility model will provide a kind of stainless steel mesh grid enhancement mode Expanded graphite seal ring exactly, it can be applicable between the not parallel flange plate that several angle is arranged between two flange plate makes sealing material, and the high temperature of ability more than 1000 ℃ also can play good seal action under highly frequent vibration condition.
The purpose of this utility model is achieved in that it is made up of Expanded graphite and reticulated, and Expanded graphite 1 and reticulated 2 are interweaved, and reticulated 2 adopts wire gazes to make, and wire gaze is the stainless steel mesh grid.
The utility model is because reticulated adopts the stainless steel mesh grid, and institute is so that the intensity of Expanded graphite increases abrasion degree reduction, and high temperature resistant.The utility model also has advantages such as simple in structure, corrosion-resistant, good springiness, good seal performance.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a sectional structure schematic representation of the present utility model.
Wherein, Fig. 1 double as Figure of abstract.
Among the figure, 1, Expanded graphite, 2, reticulated.
During making, after at first calculating the volume of moulding packing ring, be converted into Expanded graphite 1 and stainless (steel) wire 2 each accounting example again, and then blanking, Expanded graphite 1 and stainless (steel) wire 2 are bar-shape during blanking, and the 2.5-3 that width will approximate shaping cushion thickness doubly, is beneficial to like this along the thickness aspect and compresses, external diameter does not advance die cavity when being beneficial to the dress mould yet, and the length of stainless (steel) wire 2 must be shorter than the length of flexible graphite belt 1.Expanded graphite 1 tape leader is twined earlier the 2-3 circle on core rod, and then, twine the back dress mould that finishes, be compressed to desired thickness with hydraulic press behind the dress mould, form the blank of seal ring twining on the Expanded graphite 1 on flexible graphite belt 1 and the stainless (steel) wire 2 winding mold core together.
The last seal ring outer surface winding Expanded graphite 1 and stainless (steel) wire 2 one circles that will become blank more, and then by the hydraulic press packing compact forming, to the seal ring of required size.
Stainless (steel) wire 2 does not appear in the packing ring that comes out like this, internal surface, and stainless (steel) wire 2 all appears in remaining surface, whole seal ring outer surface Expanded graphite 1 and stainless (steel) wire 2 interweave, just as the fishing net shape, but hand to feel be level and smooth, such seal ring has just been made.
Claims (2)
1, a kind of stainless steel mesh grid enhancement mode Expanded graphite seal ring is made up of Expanded graphite and reticulated, and it is characterized in that: Expanded graphite (1) and reticulated (2) are interweaved, and reticulated (2) adopts wire gaze to make.
2, stainless steel mesh grid enhancement mode Expanded graphite seal ring according to claim 1, it is characterized in that: wire gaze is the stainless steel mesh grid.
