Detailed description

Carbon Kevlar packing

With aramid fiber as the main material, repeatedly dipping lubricants, lotions and other precision PTFE compiled. There is preferably a high resilience, chemical resistance, low cold flow and high line speed, and the comparison with other types of packing, the crystallization medium and the particles can resist higher temperatures. Can be used alone or combined with other packing. Mainly used for multi-media particles, easy to wear conditions.

Q:How do I remove the rubber sealing washer for the washer inlet valve?: When the dirty water filter valve plug, usually use the brush will be able to solve the problem (without dismantling), but if it is often blocked I advise you to learn I simply to filter down (with a screwdriver destructively removed), save a lot of trouble, there is not much significance for water filtration net valve washing machine, it is brought to us is the dirty block, personal opinions for reference only.

Q:The material column of some gaskets / gaskets indicates what "200HV" means Is that the hardness scale? What materials are usually used? Know the elders please advice, little brother is not very grateful!!! []: The material column of the gasket / gasket indicates that 200HV is material and the mechanical grade is steel 200HV.Examples of marking: standard series, nominal size d=8mm, performance rating 200HV, plain gasket without surface treatment: gasket GB97.1 - 858 200HVA part that is attached between a connecting piece and a nut. A generally flat metal ring used to protect the surface of a connecting piece from the scratch of the nut and to distribute the pressure of the nut on the connecting piece.

Q:What's the difference between the washer and the gasket?: The washer is divided into: -C, flat washer washer -A and grade C, grade -C large washers, washer, flat washer, flat washer, chamfered - - a grade steel structure with high strength washer, spherical washer, taper washers, square taper washers, steel I-beam, square taper washers standard type spring washers, spring washers, light heavy spring washers, lock washers internal teeth serrated lock washers, inner and outer teeth lock washers, serrated lock washers, single ear washers, ears washers, external tab washers, round nuts with washers.

Q:Treatment process of protective washer in sealed rubber ring: The cylinder ring sealing ring is divided into static and dynamic seals to bear the pressure. There will be O rings and U rings in the cylinder rings

Q:What is the basis for the classification of gaskets?: The standard of the gasket is different, and its temperature, pressure and use are different,In a word, the standard of the execution of the gasket is the basis of its classification.

Q:I found that the hydraulic joint can be used as a gasket with an aluminum pad or a copper pad, and the effect is good, but I don't know if there will be any other effect after repeated disassembly or long serviceImports of hydraulic equipment in the middle of some even no sealing ring, but spent more than ten years will not leak, but after opening and then installed on the failure, why?: The metal pad before using the best grinding, long time use is also good, but now the popular seal combination, inside is rubber, the outer ring is a metal skeleton, but also the price is disposable, and metal pad almost.Imported generally coated with sealant, so after opening and then installed on the die

Q:and it's OK to forget to put the sealing ring when changing!: It's bound to leak! Thank you. There's a problem with the car. Ask the car master. 4S shop professional technicians, 10 minutes to solve. ]

Q:The sealing principle of metal wound gasket?: Sealing gasket: metal winding principle of the sealing surface when the pressure load, to produce compressive stress, can improve the sealing contact surface, when the stress increases enough to cause the surface of the plastic deformation obviously, it can fill the gap seal cover, plug leakage channel. The purpose of using the gasket is to use the gasket material to produce plastic deformation characteristics under the action of compaction load so as to fill the small and uneven surface of the flange sealing surface so as to realize the sealing.Leakage is the phenomenon that the medium enters the limited space from the outside of the inner space of the limited space or from the outside. This is what people do not want to happen. The medium flows through the interface between the inside and outside spaces, i.e., leaks occur on the sealing surface. The root cause of the leakage is that there is a gap in the contact surface, and the pressure difference and the concentration difference on both sides of the contact surface are the driving force of the leakage. Because of the sealing surface form and processing accuracy and other factors, the sealing surface of the gap is unavoidable, which will cause the sealing surface is not completely consistent, resulting in leakage.In order to reduce the leakage, it is necessary to make the contact surface to be fitted to the maximum extent, that is to reduce the cross-sectional area of the leakage passage and to increase the leakage resistance, and to make it larger than the leakage force. In the bolt flange gasket connection, the force of the gasket causes deformation of the gasket material so as to fill the gap between the flange sealing surfaces. The magnitude of its pretension depends on the number of bolts, the torque of the tightening bolt, the lubrication state of the bolt system, and the compression area of the gasket.

Q:How much pressure can the aluminum gasket bear?: It is widely used in medicine, chemical and food industries, and is suitable for high pressure and demanding environment.

Q:What is the material of the metal ring? And the copper pad is better than that one: The combination sealing washer can be divided into A type and B type according to the structure form, and can be divided into the whole package and the half package according to the different rubber bags.Use a combination washer. It's cheap and convenient to buy.
