Liquid tank venting system comprising a chamber that is inside the tank and that is equipped with a drainage device that comprises at least one opening made in the chamber and an elastomer-based non-return valve capable of sealing/freeing this opening, according to which this non-return valve is forced into a position for leaktight closure of the opening via a specific device starting from a certain liquid level in the tank.

Liquid tank venting system

Safety valve for the venting circuit of a liquid tank Safety valve for the venting circuit of a liquid tank, comprising: a) a chamber () provided with a cover (), which extends at least partly into the tank and is connected via an aperture () to the venting circuit; b) a float (), which can slide vertically inside the chamber () and close off the venting aperture () in a high position; and c) a moveable wall (), which divides the chamber () into a lower portion (') in which the float () slides and an upper portion (&#x2033;) which connects with the venting circuit, this wall () being a moveable wall and having the venting aperture (), said valve further including an aperture stop () integral either with the moveable wall () or with the cover ().

Safety valve for the venting circuit of a liquid tank

Valve for the venting circuit of a liquid tank, the valve comprising a chamber which includes openings that allow liquid to penetrate into the chamber above a certain level in the tank and/or in the event of waves in the tank or the tank being turned upside down, a cover for the chamber including an aperture that is susceptible to open into the venting circuit of the tank, and a float comprising a body and a needle that close off the aperture, the float being able to slide vertically inside the chamber depending on the level of liquid therein, the needle of the float being frustoconical-shaped and based on an elastomeric material.
