The characteristic definition of the bottom valve

The bottom valve is an energy-saving valve, generally installed at the bottom end of the water pump underwater suction pipe. It restricts the liquid returning to the water source in the water pump pipe, and functions as an inaccessible one. The valve cover has a plurality of water inlets and reinforcing ribs. It is not easy to block, mainly used in the pipeline of pumping. The function of water channel and support. The caliber has single flap, double flap and multi-lobed shape. It has flange connection and threaded connection. Other names: internal thread lift bottom valve --- bottom valve, water suction valve, water filter valve, shower head; lift bottom valve -- flange bottom valve; swing open bottom valve -- flange swing well Bottom valve.
The bottom valve is welded to the bottom of the container, so that it can achieve the effect of emptying, cleaning and disinfecting. In addition, the working medium can be well mixed according to the various process requirements in the operation process. The bottom valve is as close as possible to the bottom wall of the tank to achieve a dead angle effect. Characteristics of the bottom valve product: 1. The structure is ideal both in terms of flow rate and process requirements, and there is no turbulence in the case of emptying. 2. Provides interfaces to all current international standards, such as welded, clamped or threaded. 3. The valve body materials are US304.SUS316L. Of course, other alloy steels can 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 precision can reach 0.25um. 5. The bottom valve can be equipped with manual or pneumatic. Each pump should be equipped with a bottom valve. The bottom valve is usually installed below the water surface, while the water-type bottom valve is installed above the water surface. It is an updated product of the old-style bottom valve. It is an ideal water diversion equipment and can also replace vacuum pumps and vacuuming devices. The water-based bottom valve was designed by the Ministry of Railways Professional Design Institute. It passed the ministerial appraisal in 1985 and won the Ministry of Railways Science and Technology Progress Award in 1986. It has been injected into the Water Supply and Drainage Design Manual, Volume IX, 90-year Energy Communication Magazine. In the second phase, the bottom valve was reported as “High-efficiency and energy-saving water bottom valve”. In 1994, in the National Double Five Hundred Activities, it was awarded the excellent energy-saving products assessed by the State Economic Commission, the Planning Commission and the Science and Technology Commission. The bottom valve has reasonable design, advanced manufacturing process, and convenient installation, use and maintenance. It has the advantages of small friction resistance, long service life and energy saving. It is widely used in pumping facilities in petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, irrigation and drainage industries.
