Definitions

  • This invention relates to a method and an apparatus for the proportioned delivery of gas quantities, especially but not exclusively of smallest gas quantities.
  • the method accordinging to this invention is characterised in that the gas is intermittently supplied in proportioned quantities to a storage space by means of a valve, and that the gas i thereafter expanded in this storage space, while the expanded gas is taken out of this storage space in a proportion dependent on the proportioned supply to the storage space. Owing to the expansion in the storage space of the small gas quantities supplied and due to the dependence of the delivery on the supply to the storage space, a very fine proportioning is possible, allowing the novel method to be used in all cases where such fine proportioning is absolutely necessary.
  • the apparatus according to the invention is character ised by a storage space and a valve for proportioned gas supply to the storage space.
  • Fig. 1 is a section through the axis of the inlet valve to the storage space
  • Fig. 2 is a section along the line IIII of Fig. 1, and
  • Fig. 3 is a section along the line IIIIII of Fig. l. r
  • Fig. 4 is a section through another embodiment of the gas proportioning valve.
  • the storage 'housing 1 is welded to the injector casing 2 to form together with housing 1 a block-like set.
  • gas proportioning may, for instance, be carried out as follows for disinfecting water by means of chlorine, for instance:
  • the water meter 7 is connected with the electrical control circuit 6 in a manner not shown and in such a way that it closes the circuit 6 for a short moment after the passage'of the prescribed quantity of water.
  • knife-edge inlet valve 3 is screwed fast to the storage housing 1.
  • the valve spindle 4 is operable in a wellproportioning space for the gas supplied at each'valve,
  • .Valve 3 is connected throughthe'pipe connection 27 with aconduit (not shown) leading to a chlorine gas container (not shown).
  • the storage space is connected with an andownstroke taking place practically suddenly, this additional gas quantity is practically negligible; Therefore, on each working course of the electromagnet 5 practically the small gas quantity enters thespace 16, which before the downstroke of the valve spindle, was in the annular space between the parts 14 and 15.
  • the gas quantity leaving the space 16 and flowing through the duct 17 depends on the difference between the pressures in the space 16 and in the injector'19.
  • the chlorine having already been mixed with water in the injector 19, is still more intimately mixed in the second injector 25. Behind this second injector 25 the water may either be supplied to the main water stream to be disinfected or the main Water stream may itself flow through the boring 24.
  • the method may be used for any other purposes than water disinfecting, such as, for instance, for narcosis. It will not in all cases be necessary to control the inlet to the storage housing 1 automatically. This may also be done by hand or in dependence on any other quantity or entity than a rate of flow.
  • the latter may be subdivided in two or more compartments.
  • a valve such as shown in Fig. 4 may be substituted for the valve according to Fig. 1.
  • the remaining portions of the apparatus may either be built as in Figs. 1 to 3 or in any other manner.
  • a connecting piece 28 is screwed into the wall of the storage housing 1, while a support 29 for the knife'valve body 30 is screwed fast to the piece 28.
  • the supply pipe 31 for the gas is connected by means of a cap screw 32 to the channel 33 supplying gas to the valve body 30.
  • a pressure-reducing valve (not shown) may be connected in series (in the pipe 31, for instance) with the valve 30.
  • the valve disk 35 cooperating with the knife edge 34 of the valve body 30 is inserted into a head 36 of the valve spindle 37.
  • a diaphragm 38 is clamped fast in a gastight manner between a collar 39 of the connecting piece 23 and a shoulder of a sleeve 40 screwed to the piece 28.
  • the nut 41 is secured against rotation by means of a spring ring 43 and a counternut 44.
  • Sleeve 45 is screwed to sleeve 40 and a sealing 46a is inserted between these sleeves.
  • Sleeve 47 is screwed to the spindle 37 and serves the latter as a guide along the bore of the flange of the sleeve 45.
  • Spindle 37 is connected with a spindle 49 by means of a threaded sleeve 48.
  • Sleeve 48 serves the purpose of adjusting the length of stroke of the valve disk 35 andis secured against rotation by means of counternuts 50 and spring rings 51.
  • a plate 53 supported on sleeve 40 and held by a nut 52 screwed onto sleeve 40 carries tubes 54 traversed by bolts 55 serving to fix the electromagnet indicated in the drawing by its housing 56.
  • Spindle 49 is coupled with the core (not shown) of the electromagnet. The latter may either be controlled in the same manner as in the first example or in any other way.
  • the valve disk 35 is intermittently controlled in a prescribed rhythm by means of the electromagnet controlled by a water meter, for instance, and lifted off the edge 34 and brought back onto this edge by spring 46. Thereby, gas flows in proportioned quantities through the channel 33, the valve 30, the space 42 and the passage 57 into the storage space 16 where it expands. With this valve, too, the ga may be finely proportioned in smallest quantities.
  • an expansion chamber an expansion chamber, a valve housing with its space in uninterrupted connection with said expansion chamber, a gas supply line discharging into said valve housing, a periodically controllable valve in said valve housing for dosed delivery of gas from said supply line to said expansion chamber, control means for said valve, controllable independently from the pressure in said expansion chamber and a valveless outlet from said expansion chamber for the continuous withdrawal of expanded gas from said expansion chamber at a rate proportional to the pressure in said expansion chamber, said pressure varying with the number of strokes of said valve per unit of time.
  • an expansion chamber comprising a space in valveless connection with said expansion chamber, a knife-edged valve body fixed to said valve housing and projecting into said valve space, a gas supply line discharging into said valve body, a periodically controllable valve head projecting into said valve space to cooperate with said knife-edged valve body for dosed delivery of gas from said supply line to said expansion chamber, a diaphragm fixed to said valve head and to said valve housing closing said valve space from the outside, and means for the withdrawal of expanded gas from said expansion chamber in quantitie continuously depending on the number of strokes of said valve head.
  • a housing comprising a gas expansion chamber, an injector casing fixed to said expansion chamber housing forming a blockshaped set, two injectors mounted in said injector casing and connected in parallel with each other, a feed line fixed to said injector casing and connected with both said injectors, a fiowmeter in said feed line, a conduit extending through said injector casing and connecting said expansion chamber with one of said injectors, a valve housing fixed to said expansion chamber casing with its valve space in uninterrupted connection with said expansion chamber, a gas supply line discharging into said valve housing, a
  • valve in said valve housing for dosed delivery of gas flOIllsaidsupply line to said expansion chamber, a drive means mounted on said expansion chamber housing and coupled with the movable part of said valve to periodically control the latter, and control means in operable relation with said drive means and said flowmeter.
