Description

A kind of sealing drilled packing ring and its production method
Technical field
The present invention relates to a kind of sealing drilled packing ring, belong to the sealing ring technical field made with metal.
Background technology
In the prior art, the less axle class sealing drilled packing ring of static or linear velocity is generally used for, is with single flexibility Material is constituted, and the structural strength of material is relatively low, it is impossible to resist the operating mode of elevated pressures, easily in use material by medium Blowout is worn and torn, and also have increases metal backup shoe or complexed metal litzendraht wire to improve material strength problem in filler ring surface, but Metal backup shoe is that smooth steel pool and flexible sealing material adhesion are poor, easily comes off during installation and occurs leakage when using and asks Topic, while metal backup shoe only exists surface, improves very limited to intensity, and metal knitted line similarly has that intensity is not high to ask Topic, and when somewhere frock problem occurs and causes that frictional force is excessive between contact surface, can run out bearing, or even can be to packing ring in itself Structure brings influence.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art, proposing a kind of low-friction coefficient airtight and watertight padding Ring.The present invention is that the technical scheme for solving above-mentioned technical problem proposition is：A kind of low-friction coefficient sealing drilled packing ring includes：It is some Layer sheet metal and sheet low-friction coefficient flexible material, the top and the bottom of the sealing drilled packing ring are the metal foil One layer of sheet low-friction coefficient flexible material, the metal foil are provided between piece, sheet metal described in adjacent two layers Multiple projecting apertures and multiple shrinkage pools that spurt processing is formed are evenly distributed with piece.
The sheet low-friction coefficient flexible material is made up of following mass percent raw material：20%~40% plant is fine Dimension, 20%~30% inanimate matter, 5%~10% size, 5%~15% lubricant, 5%~15% thickener；Wherein, the string The mass percent of each component is 10%~60% castor-oil plant line, 15%~40% linen thread, 0~20% ramie and 0~20% jute；It is described The mass percent of inanimate matter each component is 35%~65% graphite, 0~35% molybdenum disulfide and 0~35% silica, and the nothing The particle diameter of machine matter is 2500 mesh；The size is trimethoxy silane, silmethylene or the ptfe emulsion of purity 99% In one kind；The lubricant is one kind in castor-based lubricating oil, mineral base oil or the poly- ɑ olefin oils of PAO；It is described to increase Thick dose be natural polymer and its derivative, including：Starch, gelatin, sodium alginate, casein, guar gum, chitosan, I One or more in uncle's natural gum, xanthans, soybean protein glue, natural rubber, lanolin, agar.
The sheet low-friction coefficient flexible material is prepared as follows according to said components：
（1）The string normal temperature is immersed in the size 24~48 hours；
（2）Take out step（1）The string of middle infiltration carries out chopping processing, and the plant fiber length after chopping is less than 5mm；
（3）Add the inanimate matter and the lubricant successively into the first Scattered Kettle, 800 revs/min of high-speed stirreds are mixed Close uniform 10~15min；
（4）String and step after into the second Scattered Kettle, addition is shredded successively（3）The mixture of middle acquisition, fully Mixing, after 800 revs/min of high-speed stirreds, then adds into the second Scattered Kettle thickener and with 50~150 revs/min of low speed Stirring is until between the two without obvious layering；
（5）By step（4）In obtained mixture be evaporated processing with 50~80 DEG C so that final mixture reclaimed water Mass percent is between 13%~25%.What the sheet metal and flexible material layer were connected is partially submerged into the projecting apertures and recessed Kong Zhong.
The foil material is one or more combination in stainless steel, galvanized sheet, copper.The shrinkage pool and projecting apertures interval Arrangement.
It is of the invention to be using the beneficial effect of above-mentioned technical proposal：This hair is by airtight and watertight padding by the common structure of multilayer ring structure Into, sheet low-friction coefficient flexible material internal layer and outer layer be provided for support rib act on and styling sheet metal Layer, makes low-friction coefficient material not deformed because of extruding or the influence of other active forces, and filled out relative to existing Ring, its coefficient of friction between filler is smaller does not influence the normal operation of pump.
Brief description of the drawings
Fig. 1 is the schematic cross-section of the present embodiment.
Embodiment
Embodiment
The low-friction coefficient sealing drilled packing ring of the present embodiment, as shown in figure 1, low by four layers of sheet metal 1 and three-layer tablet shape Coefficient of friction flexible material 2 is constituted, and the top and the bottom of sealing drilled packing ring are sheet metal 1, and adjacent double layer of metal is thin One layer of sheet low-friction coefficient flexible material 2 is provided between piece 1, it can be seen that the double layer of metal of inner side is thin The skeleton function that piece is 1,1 styling of sheet metal in outside limits whole low-friction coefficient flexible material 2 and constituted, gold It is evenly distributed with spurt multiple projecting apertures 3 for being formed of processing and multiple shrinkage pools 4 on category thin slice 1, projecting apertures 3 and shrinkage pool 4 are by metal foil Piece 1 is fitted close with low-friction coefficient flexible material 2.
