Abstract

Current valve protection cover had problem that the hight of cover cap and road level could not match when the road was repaired and overcovered. But new developed device can solve this problem by forming several grooves in the connecting pipe. This device is devided into col=netting pipe (down side) and cap part.(upper side) On the outside diameter of connecting pipe, several horizontal grooves and two vertical grooves are formed. Through the horizontal grooves, the hight of cap part ran be adjusted with ground level. Therefore, this device can help easy maintenence in running water pipe.
