A gas canister and method of filling

 

(57) Abstract:

The invention relates and the production and filling gas gas cans. A gas canister includes a housing with an orifice, the orifice of which is inserted the tube, the flange of which is welded to the end cap and the membrane has a notch. Inside the body is placed prior to filling of the container with liquefied gas moving ball, the diameter of which is larger than the diameter of the holes in the neck, and the length of the tube is such that after sealing the tube, the ball may not completely close the opening of the neckline. The method of filling a gas container includes a closure cap gas canister tube, the injection tube and welded flange tube to the end cap. Before filling the inside of the casing of the cartridge is placed a movable valve, turn the bottle neck down and tuck under pressure liquefied gas, reduce the filling pressure with simultaneous closing pressure of the gas inside the spray hole of the neck of a movable valve with long-term storage of filled container prior to its closure stopper. The result is the ability to create structurally simple, easy to manufacture, convenient in the former the production and filling gas gas cylinders, used, for example, carbonated water in siphons, for airgun shooting, gas weapons, for inflating Bicycle tires.

The level of technology.

Known technical solutions design of the gas cans filled with gas such as carbon dioxide CO2with lid , hermetically closing the mouth of the container against leakage of gas.

As caps are used: cap, US patent N 2425448, CL 220-3, 1947, top, worn on the neck of a gas canister and welded to its front part; tube, US patent N 2630936, CL 220-3, 1953, with a cylindrical tubular skirt, which is located inside the neck of the gas bottle, and the cap has a horizontal annular flange, which is welded to the front part of the neck; the sealing plate, patent GB N 2045353, CL F 16 K 17/16, 1980, in the middle of which the upper and lower surfaces opposite to each other, there are recesses for facilitating the puncture plate and seam, welded to the end part of the neck of a gas canister, plate consists of one or two folds; two packing plates, patent EP N 0412773, CL F 17 C 13/06, 1994, the first of which seamed inside of the neck of a gas canister, and the second plate Shego gas, when the gas pressure inside the balloon increases sharply; the dome-shaped membrane, patent EP N 0258057, CL F 17 C 13/06, 1988, flange flange which is seamed at the mouth of the gas canister.

The closest analogue is the design of the gas canister, US patent N 2685383, CL 220-3, 1954, having a housing with an orifice in which is placed the body of the tube, the flanges of which are welded to the end cap.

The closest analogue of the method of filling a gas canister gas is the way, the US patent N 2685383, CL 220-3, 1954, including the placement of carbon dioxide in the form of dry ice inside the container, the closure cap of the spray tube, the injection tube and welded flange tube to the end cap.

For all of these devices and method of filling is characterized by the following common shortcomings. When charging, for example, CO2everywhere you use dry ice is carbon dioxide in the solid state. Get dry ice from liquid. Losses on the conversion of carbon dioxide from liquid to solid is ~30%. The operation of filling a gas canister, sealing spray tube and welding the tube to the neck of the bottle should be carried out for each other since the process requires the creation of complex and expensive equipment.

The essence of the invention.

The basis of the proposed technical solutions based on the idea of creating a gas canister with structurally simple, easy to manufacture, convenient in operation, a movable valve in the form of a spherical ball. Thanks a gas canister can be filled directly CO2in the liquid state, which eliminates the pre-conversion operation CO2from liquid to solid dry ice, i.e., when filling spray can reduce the loss of carbon dioxide is not less than 30%. The use of such a movable valve allows you to divide the process of making filled with a gas canister into two separate, extended in time manufacturing operations

- refill canister liquefied gas with long-term storage;

- capping the tube and welding it to the canister.

This allows to simplify the requirements for technological equipment and, consequently, reduce the production cost of gas cans.

This is achieved by a gas canister consisting of a body with a neck that has a tube that is inserted in the neck of the canister. The flanges of the tube is welded to the rivki liquefied gas is placed a movable valve the spherical ball, the diameter of which is larger than the diameter of the holes in the neck. Length is placed in the neck portion of the tube is such that after installation of the tube, the ball may not completely close the opening of the neck.

After puncture of the membrane tube, the ball could not block the access of gas from a gas canister into the tube placed in the mouth end of the tube is made with a bevel or zavalova, for example, in the form of "stars".

The ratio of average specific density of the material of the ball, and the ball diameter is selected such that after filling the gas container to the sealing stopper ball under the pressure of the gas, which is about 60 times higher than the ambient pressure, could not escape through the mouth.

The ball may be made of flexible, elastic material; made from stretchy, elastic material with a metal powder filler; all metal in elastic, elastic shell.

In the proposed method of filling a gas canister before filling into the housing of the cartridge is placed a movable valve, then turn the bottle neck down and tuck it under the pressure of the liquefied hazwaste neck so the spray can for a long time to be stored without leakage of gas from the canister, produce closure of the neck of the tube, the insertion tube and welded flange tube to the end cap.

The best embodiment of the invention.

A gas canister includes a housing 1 with the neck 2. Inside the housing 1 is placed ball 3 (Fig. 1). In grief, the recess 8 to facilitate puncture of the membrane 7. The tube end has a bevel 9 (Fig. 5) or zavalova, for example "star" 10 (Fig. 6). The ball 3 may be made of flexible, elastic material (Fig. 7), of flexible, elastic material with a metal powder filler, entirely of metal, elastic, elastic shell 11 (Fig. 8), for a snug fit to the walls of the hole 12 of the cap 2.

Refill a gas canister occur as follows.

A gas canister with a ball 3, previously accommodated in the housing 1 (Fig. 1), turn the neck 2 down and under pressure of over 10000 hPa through the neck 2 is filled with liquefied gas. Under the pressure of the gas in the canister ball 3 goes down and completely tightly closes the opening 11 of the cap 2, thus preventing the leakage of gas from the canister. The spray is turned to the normal position (Fig. 2). In this state, a gas canister can be stored for a long time. This practically eliminated the leakage of gas from the gas canister. Then there is a sealing tube 4 (Fig. 3), while the end of the tube 4 pushes the ball 3 from the hole 11 of the cap 2. Then there is the insertion tube 4 and welding its flange 5 to the end face 6 of the neck 2. Further, the ball 3 is lowered to the bottom of the gas Ballou welding of tube 4 to the neck 2 is constant (Fig. 4).

Industrial applicability.

The invention can be easily manufactured from modern materials on the basis of existing technologies and the most effective can be used for carbonated water in siphons, airgun shooting and pumping bike tires.
