The foot valve is a kind of energy-saving valve, which is generally installed at the bottom end of the underwater suction pipe of the water pump to restrict the liquid in the water pump pipe from returning to the water source, playing the function of only entering but not leaving. There are many water inlets and reinforcing ribs on the valve cover, which are not easy to be blocked, and are mainly used in pumping pipelines. The role of water channel and support. The caliber has single, double, and multi-lobe types, with flange connection and threaded connection. Other names: Internal thread lifting foot valve---foot valve, suction valve, filter valve, shower head; lifting foot valve--flange foot valve; swing foot valve--flange swing well foot valve.
The foot valve is welded to the bottom of the container to achieve the best emptying, cleaning and disinfection effects. In addition, the working medium can be mixed well according to the various technological requirements during the operation. The foot valve of the tank is as close as possible to the bottom wall of the tank, so as to achieve the effect of no dead angle.
1. The structure is ideal both in terms of flow rate and process requirements. In addition, there will be no turbulence when emptying.
2. It can provide all current international standard interfaces, such as welding type, clamp type or thread type, etc.
3. The valve body materials are US304.SUS316L. Of course, other alloy steels can also be used according to customer requirements.
4. The surface of the valve body can be mechanically polished or electro-polished according to customer requirements, and the accuracy can reach 0.25um.
5. The foot valve can be equipped with manual or pneumatic. Each water pump needs to install a foot valve. The foot valve is usually installed below the water surface, while the water-based foot valve is installed above the water surface. It is an updated product of the old foot valve. It is an ideal water diversion equipment and can also replace vacuum pumps and vacuum devices.
The foot valve has reasonable design, advanced manufacturing technology, and convenient installation, use and maintenance. It also has the advantages of low friction resistance, long service life, energy saving, etc., and is widely used in water pump supporting facilities in petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, drainage and irrigation industries.
