Rubber o-rings is the simplest parts in the field of seals,

Although rubber O-rings is the simplest parts in the field of seals, it's the best and most efficient seals. The structure of sealing part is very simple, for this reason, it could be used even in limited spaces. Furthermore, it could be used reliably as movable and immovable seals in the circumstance of big pressure and high temperature. If reasonable design, o-rings have very long life. O-rings could not only be used for its good sealing performance,but also for its mechanical performaces, it is being used widely in drive strap, tyre, controlling equipment and vibration absorber. It could be made by many kinds of raw materials,such as NBR, SBR,Silicone,FPM, ACM.


Mechanical seals are used in pumps, blowers, agitators, compressors, and other rotary shaft equipment.

Common seal gasket performance summary:
When using the valve, often according to the specific situation, change the original belt washer.Common gasket are: flat washer, rubber o-ring, rubber plastic flat gasket, ptfe gasket, asbestos rubber gasket, metal flat washer, metal profile gasket, metal wrapping washers, wave washers, winding gasket, etc.
(1) rubber flat washer, easy deformation, compression without effort, but the pressure and temperature resistant ability is poor, only for low pressure and temperature is not high.Natural rubber is, to some extent, acid-proof alkaline can use temperature should not be more than 60 ℃;Neoprene also ability some acid and alkali, temperature 80 ℃;Nitrile rubber oil resistant, available to 80 ℃;Fluorine rubber corrosion resistant performance is good, heat resistance performance is better than general rubber, can be used in the 150 ℃ medium.
(2) the rubber o-ring gasket: cross section shape is round, there was a self-tightening effect, the sealing effect is better than flat washer, smaller compression force.
(3) plastic flat washer, the biggest characteristic of plastic is good corrosion resistance, most of the plastic heat resistance performance is not good.Ptfe as the crown of plastic, not only the excellent corrosion resistance, and heat resistance range is wide, can be in within 180 ℃ ~ + 200 ℃, use for a long time.
(4) ptfe package washer: in order to give full play to the advantages of teflon, make it less elastic up at the same time, made of rubber or ptfe package asbestos rubber gasket.In this way, both with ptfe flat washer as corrosion resistance, and good elasticity, enhance the sealing effect, reduce the compression force.The cross section shape as shown in figure 4-20.
(5) the asbestos rubber gasket: by asbestos rubber sheet cut into.Its composition is 60 to 80% of asbestos and 10 to 20% of the rubber, as well as the filling agent, vulcanizing agent, etc.It has good heat resistance, cold resistance, chemical stability, and rich supply of goods, the price is cheap.When using, compaction force don't have to be very big.Because it can adhesion of metal, so it's best to coating a layer of graphite powder, so as not to remove the trouble.
Asbestos rubber sheet have four color: grey, used for low pressure (brand XB - 200, pressure or less 16 kg/cm2, heat-resistant 200 ℃).Red, used in medium voltage (brand XB - 350, pressure can reach 40 kg/cm2, heat-resistant 350 ℃).Amaranth, used in high pressure (brand XB - 450, pressure of 100 kg/cm2 and heat-resistant 450 ℃).Green, used in oil, compression performance is very good also.
(6) metal flat hot laps: lead, 100 ℃ heat resistance;Aluminum 430 ℃;Copper 315 ℃;Low carbon steel 550 ℃;Silver 650 ℃;Nickel 810 ℃;Monel nickel copper alloy is 810 ℃, stainless steel 870 ℃.One lead compression ability is poorer, aluminium can be resistant to 64 kg/cm2, other materials resistant to high pressure.
(7) metal heterosexual washer:
Lens gasket: has self-tightening effect, used in high pressure valve.
Oval gasket, also belong to high pressure washer.
Cone double gasket: used for high pressure inside the tight closure.
In addition, there is a square, diamond, triangular, tooth, dovetail, B, C, etc., is generally used in high pressure valve.
Metal wrapping gaskets 

(8) : metal has good heat resistance pressure performance, and good elasticity.Wrapping materials are aluminum, copper, mild steel, stainless steel, monel alloy, etc.Filling materials with asbestos, ptfe, glass fiber, etc.
(9) waveform washer: with a small compression force, the sealing effect good characteristic.Often in the form of metal and non-metal materials.
(10) winding gasket is brought very thin metal and nonmetal clingy together, wrapped into multi-layer circular, cross section is wavy, has good elasticity and tightness.Metal band 1 cr13 steel, 0 cr13, available, 2 cr13, 1 cr18ni9ti, copper, aluminum, titanium, monel alloy, etc.Nonmetallic materials with asbestos, teflon, etc.
Above, was telling sealing gasket performance, some Numbers are listed.Should add that these Numbers with flange form and repair and installation technology of medium has a close relationship, sometimes more than, sometimes can not reach, and pressure and heat resistance performance, and mutual transformation, the temperature is high, for example, tend to reduce the compression capacity, these subtle problems, can only experience in practice.
