The bottom valve is an energy-saving valve, usually installed at the bottom of the suction pipe of the pump, restricts the liquid in the pipe of the pump from returning to the water source and functions as a no-gain function, and the valve cover has a large number of influent products and stiffeners, Played not easy to block, mainly used in the pumping of water pipes and supporting the role of caliber single valve, double valve, multi-valve type. Flanged and threaded connections. Other names: Internal thread lift bottom valve --- bottom hole valve, suction valve, filter valve, shower head; lift bottom valve - flange bottom valve; swing-type bottom valve - Bottom valve. The bottom valve is welded to the bottom of the container to achieve the best possible emptying, cleaning and disinfection effects. In addition, according to the process requirements of the process of working medium mixed well. Tank bottom valve as close to the tank bottom wall, so as to achieve no dead ends. Bottom valve Features: 1. The structure is ideal both in terms of flow rate and process requirements, and does not generate turbulence when it is emptied. 2. Can provide all the current international standard interface, such as welding, clamp or thread and so on. 3. The valve body material is US304.SUS316L Of course, other alloy steel can be used according to customer's requirements. 4 valve body surface can be based on customer requirements using mechanical polishing or polishing, the accuracy can reach 0.25um. 5. The bottom valve can be equipped with manual, pneumatic can also be equipped with each pump to install a bottom valve, the bottom valve is usually installed below the surface of the water, while the bottom valve mounted on the water above the water, it is the replacement of the old end of the valve , Is the ideal water diversion equipment but also can replace the vacuum pump and vacuum device. Water-based foot valve designed by the Ministry of Railways Design Institute, passed the ministerial-level appraisal in 1985, eighty-six years by the Ministry of Railways Science and Technology Progress Award and has been injected into the "Water Supply and Drainage Design Manual, Volume IX, 90" Energy Newsletter "magazine The second issue of the end of the valve entitled "energy efficient water at the end of the valve," the report. In 94 years in the country double five hundred activities and won the State Economic Commission, Planning Commission, Science and Technology Commission assessed outstanding energy-saving products. The bottom valve design is reasonable, advanced manufacturing technology, installation, use, easy maintenance. And has a small frictional resistance, long life, energy saving, etc., widely used in petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, irrigation and drainage pumps and other industries supporting facilities.
