The bottom valve can be divided into plastic bottom valve and metal bottom valve according to the material, and can also be divided into ordinary bottom valve and bottom valve with backwashing water flow.
Bottom valves are mainly used in mechanical equipment for slurry treatment, such as pumps. Usually, bottom valves are installed at the bottom of the pump's underwater suction pipe to prevent slurry backflow.
At present, the quality of domestic brand bottom valves is generally poor, such as improper sealing, water leakage problems, etc. It is difficult for the system to achieve automatic control, and it is very troublesome to pour water into the suction pipe every time.
Main technical parameters
Plastic bottom valve has light weight, strong corrosion resistance, light body weight, easy to install material, sanitary, non-toxic, wear-resistant, easy to disassemble, suitable for fluids: water, air, oil, corrosive chemical liquids such as: pure water and raw drinking water pipeline system, drainage and sewage pipeline system, brine and sea water pipeline system, acid and alkali and chemical solvents.
