[Three rain valve to recommend the star product - Mechanical seal] Description: Asbestos rubber gasket: cut by asbestos rubber sheet. Its components are 60 to 80% asbestos and 10 to 20% of rubber, and filler, curing agents and the like. It has good heat resistance, cold resistance, chemical stability, and abundant supply, the price is cheap. When in use, do not have a great pressing force. Because it can adhere to metal M37G-38 mechanical seal, so it is best coated with a layer of graphite, in order to avoid the demolition strenuous. Asbestos rubber sheet in four colors: gray, for low (grades XB-200, pressure ≤16 kg / cm, temperature 200 ℃); red for medium voltage (grades XB-350, pressure up 40 kg / cm, temperature 350 ℃); purple, for high pressure (grades XB-450 mechanical seal, pressure 100 kg / cm temperature 450 ℃); green, used oil, pressure performance very well. [Three rain valve to recommend the star product - Mechanical seal] Description: Metal foreskin washers: metal both good pressure and temperature performance, and good flexibility. Wrapping materials are aluminum, copper, mild steel, stainless steel, Monel alloy. Inside filler asbestos, PTFE, glass fibers and the like. Wave washer: a clamping force is small M37G-48 mechanical seal, seal good effect. Often used in the form of a combination of metal and nonmetal. Wound gaskets: is the thin strip of metal and non-metal band close together, wrapped in layers of circular cross-section wavy, good elasticity and tightness. Available 08 steel metal band, 0Cr13,1Cr13,2Cr13,1Cr18Ni9Ti, copper, aluminum, titanium, Monel and other production. Non-metallic materials with asbestos, PTFE and so on. Above, tells the gasket performance when M37G-55 mechanical seal, cited some numbers. Must state that these figures with flange form, media, technology, installation and repair of the situation and are closely related, and sometimes more than, and sometimes can not reach, but the pressure and temperature resistance, also interchangeable, such as high temperature resistance Pressure capacity is often reduced, these subtle problems can only appreciate M37G-35 machine in practice _ Pingdingshan seal mechanical seal mechanical seal _M37G selected three rain provided by Valve Co., Ltd.
