Definitions

  • the invention relates to a valve for a fuel gas cylinder
  • the fuel gases existing at present in the market are supplied to the consumers under one of the two following physical states:
  • the distribution to the consumer is made through adequate pipe-lines.
  • the distribution to the consumer is made by using liquefied gas containers.
  • the above mentioned containers are, generally, cylindrical steel bottles, commonly named “gas cylinders” or “gas bottles”.
  • the fuel gas cylinders are fitted with a valve A (Fig. 1), 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 valve A (Fig. 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.
  • a pressure regulator B (Fig. 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 and the pressure regulator form together a necessary whole when it is required to use liquefied fuel gas from cylinders.
  • Fig. 2 it is shown a "self-closing" valve composed of the following parts:
  • Fig. 3 it is shown a schematized pressure regulator widely used all over the world. It is composed of the following main parts:
  • Fig. 4a to 4d it is shown the sequence of operations leading to the connection of the regulator to the valve.
  • Fig. 4a shows the two parts of the system in position before connection.
  • Fig. 4b 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 the clamping system has not yet reached the final security position.
  • Fig. 4c the regulator can be seen completely introduced in the valve and the security system (12 and 24) is already in the final position. However, the valve is still closed.
  • a valve for a fuel gas cylinder wherein an elastic sealing disc is lodged in a gas inlet and outlet canal of a valve body.
  • the sealing disc closes the canal.
  • the pressure regulator has a hollow needle by which the sealing disc is pierced for the consumption of the gas.
  • Fig. 2 Any of the valves known (Fig. 2) 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 is sized between 1.2 and 1.8 mm for cylinders internal pressures of 6,87 bar (7 kp/cm 2 ) and 0,49 bar (0.5 kp/cm 2 ) respectively.
  • valve can - stop guaranteeing a good gas sealing and cause danger situations and fuel gas losses.
  • Fig. 5 In Fig. 5 are shown three types of valves well known in the market. The areas subject to foreign matters are shown in vertical broken lines.
  • valves are self-closing 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 invention proceeds from a valve for a fuel gas cylinder known from FR-A-1074398, comprising a filling canal and an outlet canal closed by a perforatable sealing means which in use is perforated by a hollow needle through which the gas is delivered.
  • the object is accomplished in that a spring loaded check valve is provided in the canal and that the sealing means is provided with a cylindrical part having an axial bore, the cylindrical part being fitted within the canal, whereby on use the needle extends through the bore to open the check valve.
  • the valve is composed as shown in Fig. 6 and the components are as follows:
  • the regulator is composed as shown in Fig. 7 in gas closed position.
  • the components are as follows:
  • FIG. 9a ⁇ 9c it is shown the Valve-Regulator system in its sequential connecting positions.
  • valve is threaded in the cylinder upper part and it is submitted to filling operation without the parts 29 and 30 (Fig. 8a). In this stage the ball 28 is actuated by the spring 34 against the seat 33.
  • 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 part 30 being made in brass-sheet and having a central hole 56 and the part 29 (see Fig. 6 and 9a-9c) 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 in Fig. 9a-9c).
  • the cylinder is sent to the consumption place where the pressure regulator is adjusted to it (see Fig. 9a-9c).
  • Fig. 9a it is shown how the regulator is applied.
  • the needle-shaped gas inlet connection 36 with an outside diameter of 2,5 mm will be piercing (Fig. 9b) 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 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. 8a.
  • 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 (Fig. 10a-10c) 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. 10b).
  • 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.
