The foot valve is an energy-saving valve and a type of check valve. Generally installed at the bottom of the underwater suction pipe of the water pump. It restricts the return of liquid in the water pump tube to the water source, and has the function of only entering but not exiting. There are many water inlets and reinforcing ribs on the valve cover to prevent clogging. It is mainly used in water pumping pipelines. The role of water channels and supports. The calibers include single-valve, double-valve, and multi-valve types. There are flange connections and threaded connections. Other names: Internal thread lifting bottom valve—well bottom valve, water suction valve, water filter valve, shower head; lift-type bottom valve–flange well bottom valve; swing-type bottom valve–flange swing well Bottom valve. The bottom 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 well mixed according to various process requirements during the operation. The tank bottom valve is as close as possible to the tank bottom wall to achieve the effect of no dead ends.
Bottom valve product features:
1. The structure is ideal in terms of flow rate and process requirements. In addition, there will be no turbulence during emptying.
2. All current international standard interfaces can be provided, such as welding type, clamp type or thread type, etc.
3. The valve body materials are US304 and 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 electropolished according to customer requirements, and the accuracy can reach 0.25um.
5. The bottom valve can be equipped with manual or pneumatic.
Each water pump must be equipped with a bottom valve. The bottom valve is usually installed below the water surface, while the above-water bottom valve is installed above the water surface. It is an updated product of the old-fashioned bottom valve. It is an ideal water diversion equipment and can also replace vacuum pumps and Vacuuming device. The water-type bottom valve was designed by the Professional Design Institute of the Ministry of Railways. It passed the ministerial appraisal in 1985 and won the Scientific and Technological Progress Award of the Ministry of Railways in 1986. It has been included in the ninth volume of the “Water Supply and Drainage Design Manual” and the second volume of the “Energy Communication” magazine in 1990. In this issue, a report titled “Energy-Efficient and Energy-Saving Water Bottom Valve” was published on this bottom valve. In 1994, it won the title of Excellent Energy-Saving Product rated by the State Economic Commission, Planning Commission and Science and Technology Commission in the National Double Five Hundred event. The bottom valve has reasonable design, advanced manufacturing technology, and is easy to install, use and maintain. It has the advantages of small 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 and other industries.
