[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal, the full name of the mechanical seal, most people in the industry used to be called the mechanical seal. It is a method used to solve the seal between the rotating shaft and the body of the apparatus. By at least one axis of rotation perpendicular to the face of the fluid under pressure and the elastic compensating means (or magnetic) effects and secondary seal with the relative sliding holding stick combined to constitute the means to prevent fluid leakage, commonly used in pumps, compressors, the reaction stirred tank, etc. rotary fluid machinery, but also for a gear box, valves, rotary joint, stern shaft seal. So H75N-60 mechanical seal, mechanical seal is a universal seal device. [Three rain valve to recommend the star product - Mechanical seal] Description: metal flat hot laps: lead, temperature 100 ℃; aluminum 430 ℃; copper 315 ℃; low carbon steel 550 ℃; silver 650 ℃; nickel 810 ℃ ; Monel (nickel-copper) alloy 810 ℃, stainless steel 870 ℃. Which lead voltage capability is poor, aluminum can withstand 64 kg / cm, other materials can withstand high pressure. Metal heterosexual washers: Lens gasket: a self-tightening effect H75N-120 mechanical seal, for use in high-pressure valves. Oval washers: high pressure from the tight gasket also belongs. Double cone washers: for high-pressure self-tight seal. In addition, there is a square, diamond, triangle, tooth, dovetail, B type, C-shaped, generally used only in high pressure valves. H75N-100 machine seals, mechanical seals selected three rain (certified), Yichang mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd.
