Description

Quick open closures {QUICK OPEN CLOSER}

The present invention relates to a quick-open closure, and more particularly, to a quick-open closure capable of quickly and efficiently sealing an inlet of a pipe while simplifying its structure.

The pressure vessel is a fluid vessel that stores high pressure liquid or gas without changing volume such as a steam boiler, an air tank, a hydraulic device, an internal combustion engine, and the like. Various types such as Drum, Tower, Holder, Reactor, Storage Tank, . These pressure vessels are used for storage and exchange of high-pressure fluids in the fields of fine chemicals, petrochemicals, power plants, etc., and for thermal energy exchange and control of fluids. Since commercial operation is carried out under dangerous conditions such as high pressure, high temperature and ultra low temperature, It should be designed and manufactured with an emphasis on reliability.

On the other hand, the pressure vessel must be shielded from the outside in order to receive the fluid having a pressure higher than the atmospheric pressure in the inner space. Without such interception, the pressure of the fluid in the inner space is drastically reduced. A lid, or quick open closures, with a locking device is used to shut off the internal space of such a pressure vessel from the outside. Such quick open closures must be opened as needed and the release of the locking device is required for this. However, conventional locking devices, such as latching or bolting, are subject to limitations where rapid release of the pressure vessel is required, since release of the locking device is sequential. Therefore, a new type of locking device for rapid opening and closing of the pressure vessel is needed.

In addition to such pressure vessels, quick-open closures are widely used to open and close the inlet and outlet in various pipes and in-and-outs of hulls.
