Q:What are the standards for sealing gaskets? Urgently, hope you sent me in the following or recommend this standard website to me, thank you.: Gasket standards are the following: to the left to the right, | gasket standard GB/T 4622.1 - 2003 GB/T 4622.2 - Classification of spiral wound gasket 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gasket size GB/T 9128 - 2003 steel preparation of metallic ring gasket for pipe flange size GB/T 9129 - 2003 non metallic flat gaskets for pipe flanges technical conditions of GB/T 9130 - 1988 steel pipe flange connection metallic ring gasket for technical conditions of GB/T 13403 - 1992 large diameter carbon steel pipe flanges with a gasket GB/T 13404 - 1992 pipe flanges polytetrafluoroethylene envelope gaskets for GB/T 14180 - 1993 winding the type of gasket testing method of GB/T 15601 - 1995 pipe flanges with metal cladding gasket GB/T 19066.1 - 2003 flexible graphite corrugated metal gasket branch GB/T 19066.2 - 2003 flexible graphite metal gaskets for pipe flange gasket size GB/T 19066.3 - 2003 flexible graphite metal gaskets specification GB/T 19675.1 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket size GB/T 19675.2 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket technology JB/T 87 - 1994 pipe flanges for asbestos rubber gaskets for JB/T 88 - 1994 pipeline flanges with metal serrated gasket JB/T 89 - 1994 pipe flange metallic ring gasket for JB/T 90 - 1994 pipe flange Spiralwound gasket for JB/T 6628 - 1993 flexible graphite composite (plate) pad JB/T 8559 - 1997 JB/T 4718 - 1992 metal gasket pipe shell type heat exchanger with metal gasket JB/T 4719 - 1992 for shell and tube heat exchangers gasket

Q:How do you get that washer in the lid of the beauty cooker?: The beauty of my rice cooker washer is off, the installation is as follows: the metal part is shared with several screws and electric rice pot cover layer together, the metal part alone cannot open,

Q:The engine cover, or valve cover, cylinder head cover, the cover is the engine.This is my graduation project... The NASTRAN is used, but the rest of the software is basically the same.Hope to have experienced master Zhidianmijin ah.At present, only 12 order free modal analysis is performed. The final is to do static strength, sealing. The details of the process are not clear. For example, how does the bolt hole bind? Does it hold all the points on the inside surface? What about the boundary conditions and loading? It has more than ten bolt holes, one ring gasket, and 120 0.7bar pressure inside. The material is engineering plastics.Or some people know the whole process from modeling to the results of the general steps to say, you can, thank you first. OK, add more. StopFrequency response and transient response are currently being done: What a big question you asked! I'll tell you a little about it. I hope it will help you.Let's first talk about frequency response analysis!1. study the specialized finite element mesh division soft (HyperMesh)If you have plenty of time, first learn about the finite element mesh, like Hypermesh. The mesh is pretty nice. And you'll probably use it later on,.2. establish the calculation modelGroup the mesh models into Patran, and then combine them with paste and other functions. As for the bolt hole, you can fix the inner surface. If someone asks you for a reason, you can say that the result is conservative, and that's how it works in Engineering3. detailed steps, you can find reference books.I haven't done it myself for tightness. I'm not sure about my point of view. First of all, the problem is thermal gas solid coupling. Ha ha, seems very complicated. I don't know. I understand, right?Suggest you change ABAQUS software, try it. I'm not sure. There are plenty of examples in each software that you can take a look at. The ABAQUS help file has examples of thermal coupling and fluid solid coupling. You combine these two examples to see. What might be like?

Q:Does the seal used in the pneumatic hydraulic industry contain fasteners, gaskets (stainless steel, copper, aluminum, nylon)?: Copper, aluminum, nylon, gaskets are generally used as gaskets, stainless steel gaskets can not be used as seals.

Q:What kind of material is rubber gasket?: Silicone rubber seals are excellent in heat resistance, cold resistance, aging resistance, and insulation. Silicone rubber gaskets are mainly used in water heaters, electric irons, microwave ovens and mechanical sealing industries, and do not apply to direct contact with the human body seal position. The gasket is similar to fluorine rubber seal characteristics and silicone rubber, but the high temperature resistance and cold resistance than silicon rubber and fluorine rubber seal has excellent weathering resistance, ozone resistance and chemical resistance. Most of them apply to diesel engines, fuel systems, and chemical plants. The hydrogenated nitrile rubber gasket has excellent corrosion resistance, tear resistance and compression resistance. It is suitable for washing machines, automotive engine systems and refrigeration systems using new environmentally friendly refrigerant R134a. Polyurethane rubber gasket mechanical performance is very good, wear-resistant, high pressure resistance performance is far superior to other rubber, suitable for high pressure, wear resistance, sealing links, such as hydraulic cylinders, cylinders, etc.. Chloroprene rubber sealing pad sunlight resistant, weather resistant performance is very good, not afraid of two chloro two methyl fluoride and ammonia refrigerant, sealed environment and various aspects of application in various contact air, sunlight, ozone resistant, chemical resistant.

Q:How about the valve gasket?: (4) when the thread sealed with teflon film with raw materials, the raw materials with the beginning at stretching and thinning, pasted on the thread surface, and then start with to get rid of excess raw material, to make the film close to the thread forms a wedge as the thread gap, generally one to two ring winding, the winding direction should be with the screw, the terminal will start at the coincidence, gradually breaking with raw material, make into wedge, so as to ensure the winding thickness, the screw thread ends before the film pressing, so that together with raw materials with thread is screwed in the screw, screw, hard to slow even appropriate, don't tighten loose, avoid the roundabout, otherwise easy to leak.

Q:What is the function of the belt gasket in the water heater?: This kind of sealing product has excellent lubricity and wear resistance. On the liquid mixing device with liquid and solid phases, the outstanding characteristics can be displayed

Q:The difference between asbestos free gaskets and non asbestos gaskets: Non asbestos gasket is according to the international use of the new products, namely, high temperature resistance, high pressure resistance, corrosion resistance, the product is, according to the requirements of specific conditions, the non asbestos sealing material (non asbestos non asbestos plate, compression plate, non asbestos non asbestos materials, mold or various) stamping tools, sealing products of various shapes and the shear.

Q:I would like to ask how that kind of sealing gasket is made and processed. That's the kind of gasket that is thin in the bottle lid. What kind of PE material can be worked out with a machine and a grinding tool? ~ thank you ~!: The mould calculates the size of the gasket according to the bottle cap, then opens the mold according to the size of the gasket, then puts the raw material of the gasket into the mold, applies the press to the pressure, and finally processes the gasket

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)
