Claims

[Scope of Claim for Utility Model Registration] (1) A connector for connecting a liquid outlet hose to a through hole formed in the tank wall of an FRP liquid storage tank, which has a threaded portion formed on the outer surface. Further, the O-ring for sealing that contacts the inner surface of the through hole in the tank wall is connected to a cylindrical passage member that is positioned and attached via a receiving groove formed in the middle, and a pair or one fixing member. Then, each fixing member is screwed together from both sides of the passage member inserted into the passage hole in the tank wall, or one fixing member is screwed from one side, and the fixing members or one fixing member and the passage member are formed at one end of the passage member. A connecting device characterized in that a passage member is fixed to a through hole by pressing the inner and outer surfaces of a tank wall with a flange portion. (2) A connecting device for connecting a liquid outlet hose to a through hole formed in the tank wall of an FRP liquid storage tank, consisting of a passage member, a fixing member, and a connecting member, the passage member being It has a cylindrical shape with a fixing flange on one end and a threaded part on the outer surface of the other end, or threaded parts on the outer surface of both ends, and the threaded part when inserted into the through hole of the tank wall. It is fixed to the through hole by screwing the fixing member into the tank and pressing the inner and outer surfaces of the tank wall between the fixing flange and the fixing member or between the fixing member and the fixing member, The connecting member consists of a fitting part, a contact flange part following this fitting part, and a hose connection part following this contact flange part, and a sealing O-ring is inserted into the fitting part through a receiving groove. and is connected to the passage member by abutting and fixing the abutting flange part to the fixing member or the fixing flange part with this fitting part fitted to the passage member. A connecting device characterized by: (3) A claim characterized in that the abutting flange is pressed against and abutted against the fixing member or the fixing flange by an auxiliary member fixed to the fixing member or the fixing flange. 2) Connections listed.
