Product Description
Product DescriptionFRP flap gate ,FRP fiberglass flap valve, FRP check-stop valve for drain water back FRP check-stop valve is mainly made of non-saturated polyester resin as a base, making to sheet and then molding into production.According to material , there are cast iron check-stop valve, steel check-stop valve, FRP check- stop valve. According to shape, there are square,round, pontoon flat,flat flap check-stop valve.FRP check-stop valve installed at the end of the drain pipe , prevent the external water flowing back. It is composed of a valve seat , a sealing ring and a hinge.SpecificationMaterial Fiberglass FRP/grpSize D300-D1000mmTemperature:-20°C-60°C (requirements under the maximum design 3.temperature 120 °C flap valve)Working pressure:1-1.6MPaOpening angle of the cover>75°Closed time<2sProduct detailsFRP check-stop valve is used in water conservancy engineering system, municipal sewage engineering, urban flood control and drainage, sewage treatment plant, hydropower station, water supply plant, fish pond and so on.Applicable medium: water, drinking water, reiver water, sea water , domestic and industrial sewage water.Packing & DeliveryProduct FeaturesGlass fiber and fabric reinforced polymer composites flap valve basic characteristic1. Excellent mechanical properties, physical properties This material density is usually 1.8-2.1g/cm which is about steel 1 / 4. Tensile strength is 160-320 MPa. Specific strengthachieves 100-168. (The physical properties shown in Table 1) Coefficient of thermal expansion similar to steel, thermalconductivity is only 0.5% of steel. It is a good thermal and electrical insulation material.2. Chemical resistance, long service life A polymer matrix composite material with special chemical resistance in the corrosive medium shows that other materials can not match the superiority of. No recycling value.3. Design flexibility, product mix performance It can be enhanced by changing the resin system or material to adjust the physical and chemical properties of the product to suit the needs of the media and working conditions. Through structural layer thickness, layer design and product design to adjust the carrying capacity of the product. Made the performance of different pressure and some special products, which are isotropic metal materials, can not be compared with.Related Products
