DEVICE FOR COMBINING DISCHARGE PORT AND WATER SUPPLY PORT IN DEEP WELL OF GROUNDWATER

摘要

PURPOSE: A combining device of a discharge port and a water supply port in a deep well of groundwater is provided to improve the quality and the reliability by combining without leakage while maintaining an inner diameter of an outer casing and by assembling and dismantling easily while a sealing structure. CONSTITUTION: A lower disk ring is combined with an outer casing by welding. A water supply port case is combined with the outer circumference of the lower disk ring by welding and provided with a water supply port. An upper disk is loaded on the upper part of the lower disk ring and provided with a sliding rail(17) to slide a pumping head(21). An advancing/tightening device(9) advances the pumping head by fixing in the upper disk. The pumping head contains a sliding plate(18).
