Abstract

PROBLEM TO BE SOLVED: To simplify a work, such as maintenance and inspection, only through disassembly of only a vent pipe by a method wherein a valve casing is freely taken in and took out through an opening and communicated and connected to the vent pip and, a cover to close the opening is removably mounted on the housing. SOLUTION: All of valve elements are contained in a valve casing 3 and contained in the chamber 1d of a housing 1 and insulated from the outside by a cover 2. In a work to exchange, maintain, and inspect the parts of the valve element in the valve casing 3, a screw 2a is unscrewed and only by removing the cover 2 from the housing 1, the valve casing 3 can be taken out and exchanged with a new one as it is and contained in the chamber 1d. Thus, as against a conventional type wherein it is needed that a piping containing the vent pipe is disassembled, the above work is completely unnecessary to make, and maintenance and inspection are practicable in a short time.

The valve casing 3 can be put in and taken out of the housing 1 in a cartridge type in advance as a unit. In addition, when unloading from the tank truck 53 as shown in FIG. 5, the gas pressure from the tank truck 53 is used. The pressure in the underground tank also rises. As a result, at the time of unloading, the valve body 4 rises to the position where it closes the valve hole 6a, and the release of gas from the ventilation pipe 50b is blocked.
Further, when the internal pressure in the underground tank rises abnormally during unloading, the sub valve seat 6 also receives the internal pressure and rises, and the pressure in the underground tank can be released to the atmosphere.
