Nonmetal compensator is mainly composed of skin, stainless steel wire mesh, 6 part cotton insulation, insulation filler layer, frame, cylinder etc.:
1, skin skin is the main telescopic nonmetal compensator, is by the excellent performance of silicone rubber or PTFE high silica and alkali free glass silk floss layer compound and into, is a high strength sealing composite material. Its role is to absorb the expansion, prevent leakage, leakage and rain.
2, stainless steel wire mesh is nonmetal compensator lining, stop the circulation medium in the debris into the compensator and prevent thermal insulation material of the compensator is outward dissipation.
3, cotton insulation is both nonmetal compensator in thermal insulation and air tightness of the dual role, it is made of glass fiber cloth, high silica cloth and all kinds of insulation wool blanket, covering the width and length of the outer, has good extensibility and tensile strength.
4, thermal insulation filler layer is the main guarantee nonmetal compensator and heat insulation, which is composed of a multilayer ceramic fiber and high temperature resistant material, its thickness according to the circulation of medium temperature and high temperature resistant materials such as the thermal conductivity is determined by heat transfer calculation.
5, framework is profile bracket nonmetal compensator, ensure adequate strength and stiffness, frame materials should be compatible with the medium temperature. In 400 ℃ Q235-A600 ℃ or stainless steel heat-resistant steel. General with the mating flange plate connection.
6, draft tube is the guide and protect the role of insulation layer. The material should be consistent with the medium temperature. Material should be of corrosion and abrasion resistant. Draft tube should not influence the displacement compensator.
