Check valve, also known as one-way valve, check valve, back pressure valve, this type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve. The function of the check valve is to prevent the backflow of the medium, the reverse rotation of the pump and its driving motor, and the discharge of the medium in the container. Double-plate check valve is a very common type of check valve. By choosing different materials, the wafer check valve can be applied to water, steam, oil in petrochemical, metallurgy, electric power, light industry, food and other industries. , nitric acid, acetic acid, strong oxidizing medium and urea and other media.
Rubber flap check valve The rubber flap is made of steel plate, negative rod and reinforced nylon cloth as the backing, and the outer layer is covered with rubber. The valve flap switch life can reach 1 million times. The valve adopts the design of full flow area, which has the characteristics of small head loss, not easy to pile up various debris, and easy maintenance. The valve is mainly suitable for water supply and drainage system and can be installed at the water outlet of the pump to prevent backflow and water hammer from damaging the pump. The valve can also be installed on the bypass pipe of the water inlet and outlet pipes of the reservoir to prevent the backflow of pool water into the water supply system.
