Abstract
This invention relates to the distribution, in free air, of the liquid phase of a cryogenic fluid which is stored under pressure. The apparatus consists of a phase-separator, a collecting tank for the liquid phase, an electrical system for controlling an electrical valve in order to hold the level in the tank constant, an adjusting member and distributor means. The invention is applicable to the inertizing of metallurgical furnaces or moulds, the protection of casting jets and molten metal, to the filling of containers, etc.
Claims14
Apparatus for delivering the liquid phase of a cryogenic fluid to a point open to free air at which it is to be used, said apparatus comprising in combination:
- a. a tank in which said cryogenic fluid is stored under pressure;
- b. a phase-separator having an infeed duct connected to said tank to allow said fluid, which is delivered in the form of a two-phase mixture, to pass to said separator, and discharge means to allow the liquid phase of said mixture to flow out by gravity, said infeed duct being provided with a member for regulating throughput which can be remotely actuated;
- c. a liquid-collecting container which is fed by said discharge means and having outlet means to allow the body of liquid collected in said container to flow out by gravity;
- d. a system to control said throughput regulating member which is sensitive to the level of liquid in said container and which is provided to maintain said level constant;
- e. adjustable-throughput withdrawal means which are connected to said outlet means from said containers;
- and
- f. distributor means connected to said withdrawal means which deliver the said liquid to said point at which it is to be used.
