Definitions

  • the fuel gases existing at present in the market are supplied to the consumers under one of the two following physical states:
  • the above mentioned containers are, generally, cylindrical steel bottles, commonly named “gas cylinders” or “gas bottles”.
  • valve a component part 1 ( D wg. No. 1) named "valve”, which is generally threaded in the upper part of the cylinder.
  • This component part owing to its characteristics and through an adequate operation allows to establish a communication between inside and outside of the cylinder, allowing thus both the gas inlet into the cylinder (filling) and the gas outlet from the cylinder (consumption).
  • the part 1 (Dwg. No. 1) performs in full its function in the cylinder filling operation, but it is not enough to permit the normal consumption of the gas contained in the cylinder. This happens because the gas is not generally consumed at the pressure at which it is liquefied into the cylinder.
  • pressure regulator 2 (Dwg. No. 1) which is adjustable to the “valve” and receives through it the gas coming from the cylinder reducing its pressure to the values required by legal rules existing for the consumption of liquefied fuel gases.
  • valve it is convenient to emphasize that what will be exposed next is referring to “self-closing” valves and therefore it will not be of interest to refer here to “manual-closing” valves, as our invention is mainly useful in “self-closing” valves although it can be used too in “manual-closing” valves.
  • the fig. 1 shows the two parts of the system in position before connection.
  • the regulator was introduced in the upper part of the valve and the regulator inlet connection 11 can be seen introduced at the valve outlet canal 2 passing through the connection joint 6 but the clamping system has not yet reached the final security position.
  • valves known has a canal 2 allowing the passage between the interior and exterior of the cylinder. This canal allows the cylinder to be filled with gas and it is also suitable (in the inverse direction) for the gas outlet for consumption.
  • the referred canal diameter which varies according to the manufacturer, is usually of 6 to 8 mm.
  • This diameter has to be of this size so that the cylinder filling is made quickly (15 to 20 seconds) in order that the filling plants are profitable.
  • the discharge capacity of this canal is very excessive in respect of the normal consumption requirements, as the average consumer would consume a cylinder content within 15 to 20 days.
  • the relation between the filling speed and the normal consumption speed in the referred canal assuming that the useful time of utilization is 10% of total time to empty a cylinder (15 days) at the consumer home, will be:
  • valve outlet canal diameter to guarantee the normal consumption gas flow is sized between 1.2 and 1.8 mm for cylinders internal pressures of 7 k g/cm 2 and 0.5 kg/cm 2 respectively.
  • the inlet and outlet canal 2 (Dwg. No. 1) existing in the conventional valves has the suitable diameter for a quick filling, but it is very excessive for the consumption.
  • a gas leak can occur more easily during the consumption because larger diameters have to be used in the valve-regulator connection than those really necessary.
  • valve can stop guaranteeing a good gas sealing and cause danger situations and fuel gas losses.
  • valves are self-clos - ing type, these systems would be useless if it there would be smaller sections in the connecting area, what would reduce, as it can be seen in the Table I (Capsula System), the total ejection force exerted in the regulator to insufficient values to eject it.
  • the valve is composed as shown on Dwg. No. 6 and the components are as follows:
  • the regulator is composed as shown on Dwg. No. 7 in gas closed position.
  • the components are as follows:
  • valve is threaded in the cylinder upper part and it is submitted to filling operation without the parts 29 and 30 (fig. 1 - Dwg. No. 8). In this stage the ball 28 is actuated by the spring 34 against the seat 33.
  • a device 54 (Dwg. No. 8) specially studied for that purpose which is connected to the high pressure gas line.
  • the gas under pressure will pass into the canal 31 forcing the ball 28 to come down. Then the gas will pass between the seat 33 and the ball 28 to inside of the cylinder.
  • the parts 29 and 30 are introduced in the upper part of the valve by means of a special device 55 (Dwg. No. 8) which effects not only this introduction but also clips firmly part 30 in the groove 53 existing in part 27 guaranteeing thus the complete tightness and inviolability of the gas cylinder.
  • a special device 55 Dwg. No. 8 which effects not only this introduction but also clips firmly part 30 in the groove 53 existing in part 27 guaranteeing thus the complete tightness and inviolability of the gas cylinder.
  • the part 30 being made in brass-sheet and having a central hole 56 and the part 29 (see Dwg. Nos. 6 and 9) being designed with a special shape are allowing the introduction through them of the regulator gas inlet connection 36, which will be adjusted in the internal orifice of part 29 (2.5 mm diameter) as shown on Dwg. No. 9.
  • the cylinder is sent to the consumption place where the pressure regulator is adjusted to it (see Dwg. No. 9).
  • the needle-shaped gas inlet connection 36 with an outside diameter of 2,5 mm will be piercing (fig. 2) in the center of the part 29 through the hole 56 existing at the center of part 30 and it will be introduced in the referred part, jointing closely, in order to guarantee a good gas sealing between parts 29 and 36.
  • the gas will pass then up to the regulator chamber 51 but it will not reach the outlet canal 38 because the gas on-off system composed of parts 37, 46, 47, 48, 49, 50 and 52 is in the most advanced position, closing the chamber 51 owing to the action of spring 49 (fig. 2).
  • the on-off plunger 47 will be maintained at its most backward position by the gas pressure action in chamber 51 which actuates on the forward surface of on-off plunger.
  • the two O-Rings 48 are operating now as piston rings.
  • the consumer will remove the regulator from the valve and will send the cylinder with the valve to the filling plant.
  • the filling plant must remove the parts 29 and 30 from the valve so that the system comes back to the same position as indicated in 5.2.1 and according to fig. 1 (Dwg. No. 8).
  • the parts removal operation is named "decapsulation”.
  • the part 29 is made in synthetic rubber and its sizes studied in such a way that, when exerting a compression with a specially designed device 57 (Dwg. No. 10) at its top the volume of the rubber contained between the parts 27 and 30 flows hydraulically to the periphery exerting an adequate force in the interior surface of the "capsula” 30 to extract it from the groove 53 (fig. 2 - Dwg. No. 10).
  • a specially designed device 57 Dwg. No. 10
  • the parts 29 and 30 are then removed from the top of part 27 and they must be scraped.
  • the valve will be now in conditions to allow a new filling operation and then a new cycle can start.
