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:Why does Richell Richell plastic cups have a washer?

This is the unique double leak proof design of Richell. They have plastic drinking cups.

Q:What kind of gasket does flange have? What standard does it have?

Non metallic flat gaskets for HGT 20606-2009 steel pipe flanges (PN Series)

Q:How do you use them? One hundredAre there any expanded PTFE gaskets in China? How about with Joe?

Expanded PTFE gaskets are truly advanced and unique materials. The utility model has the advantages of creep resistance, cold resistance, ultra-low temperature resistance, pollution free, easy installation and disassembly and replacement. Under very small preload, even under pressure change, it can withstand considerable internal pressure. It is very suitable for rough or abrasion, uneven and fragile glass surface flange, alternating temperature sealing.PTFE gasket technical parameters:PTFE gasket pressure is less than 10MPaPTFE gasket temperature are less than 250PTFE gasket density 2.1-2.3g/cm3PTFE gasket pH value 0-14Filling PTFE gasket pressure 16MPaFilled PTFE gasket pressure is less than or equal to 260 DEG CThe bulk polytetrafluoroethylene temperature is -268 DEG C and ~315 DEG CExpanded polytetrafluoroethylene pressure 21MPa

Q:The outer ball tooth ring sensor mud suede cover gasket what use to send

In the light seal, as well as the use of rubber bellows as an auxiliary seal, rubber bellows elastic limited, generally need to be supplemented with spring to meet the loading elasticity. Mechanical seals are often referred to as "mechanical seals"".

Q:What is the difference between the sealing ring and the dust cap on the bearing?

Bearing belt, dust cover and sealing ring, two different performance. Refer toOne is dustproof and the other is sealed. Dust prevention is to prevent dust from entering the inside of the motor; the seal is not only not allowed by outside dust, but also not easy to flow out of the inner fat. Grease that is not clean is not easy to flow through. In practice, there is a difference between the two, but not too much. Bearings are generally internal and external oil cover, has played this role, only under certain conditions only need. Dust proof is indicated by Z and sealed by S. (felt ring seal is expressed by FS; rubber seal is expressed by LS).

Q:What is the function of the washer between the end cap and the case?

Buffer, the amount of thermal deformation reserved.

Q:What is the standard for ASME GASKET?

A gasket (washer) is a hole (usually in the middle) of a thin plate (usually round), usually used to distribute threads of load fasteners. Other uses are used as spacers, springs (Baer, gasket, wave washer), wear-resistant pads, pre display devices, and locking devices. Rubber gaskets are also used on taps (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets are also available to reduce vibration of the fan. Usually the outer diameter of the gasket is about two times the inside diameter.

Q:Why is copper gasket always leaking out of the sealing surface?

The sealing surface of two different material substances in contact is generally cast iron, cast iron due to the thermal expansion coefficient of copper with different period of time when the heating operation of the equipment, will not leak in a short time, but when the device stops again after operation will be oil leakage.

Q:Does the gasket have brass? What's the standard?

Therefore, generally used in the combination of the installation of groove, such as: male and female with the flange, valve cover, pressure gauge, live joints, etc.Standard thickness and diameter, thickness according to the sealing joint gap size to determine, size according to the size of the sealing groove needs to be processed
