  • REGULATOR FOR THE GAS SUPPLY is-Sheet 1 Filed Jan. 12, 1951 Il sa l l f 3 O i ,l 'l l/ 32N l l 8 oct. 25, 1932. F w, STOCKMEYER l l 41,884,349
  • This invention relates to the regulators for gas 'heated hot water arrangements whlch are operated by the drop ofv pressure occurl that the stroke or lift of the mam gas valve is completely dependent uponthe stroke ⁇ or lift of the hydraulic valve.
  • the h draulic valve usually consisting of a diaphrragm has to have a great liftso that it quickly becomes worn out. fi;
  • the present invention has been devised to the gas valve operated'by the hydraulic valve is arranged as a controlling valve in a controlling gas pi e which connects the hi h pressure side o the main gas valve with t e controlling pressure side of the same, which is adapted to be opened to atmosphere.
  • the invention consists further in that both sides of the controlling as valve are connected to the Ventilating pipe of the main gas valve by channels provided with throttle A thermostat-valve which automatically closes when the lighter llame is extinguished is arranged in the Ventilating pipe.
  • the gas pipe leading to the lighterburner is preferably used as av Ventilating pipe for the controlling-chamber of the main gas valve.
  • a further feature of the invention consists in that the throttle in the water pipe at which the differential-pressure serving for the op erationof the hydraulic valve isproduced is connected by a hollow shaft supporting the throttle element to the controlling chamber of the hydraulic valve, the diaphragm walls of which support and guide the hollowshaft.
  • Figure 1 is a section through a controlling gas valve which is integral with the hydraulic valve device.
  • Figure 2 shows the connection of this mechanism to a preure controlling main gas valve and to a lighting burner, supervised y a thermostat.
  • Figure 7 is a section through a gas valve and a hydraulic valve device arranged separately.
  • the hydraulic valve 'shown in Figure 1' comprises two water chambers 1 and 2 and a gas chamber 3 which is located therebetween and is provided with a controlling gas valve 9.
  • the water chamber 1 is connected by a connecting tubeV 4 to ,the water feeding pipe.
  • the water can flow out of the chamber 1 to a '75 hot water boiler through a Venturi restriction 5 and a tube 5a connected thereto.
  • the two water chambers 1 and 2 are separated from the gas chamber 3 by diaphragms 6 and 7.
  • the centres of the diaphragms are conv nected together-by a hollow shaft 8 which is guided by them and carries the plate valve 9.
  • Thisl plate valve is adapted to rest on a seating 10 in the gas chamber 3 and thereby divides this chamber into two compartments 11 and ⁇ 12.
  • the compartment 11 has a bore 13 for theV connection of the compartment to the main gas pipe, whilstk the compartment l12 has a bore 14 for the connection of the compartment to the controlling chamber nected through transverse channels 20 to the passage space ofthe Venturi restriction 5 at a point Where there is the greatest velocity of flow.
  • the opposite end of the bore 19 opens into the Water chamber 2. Springs 21 tend to lift the plate valve 9 from its seating l0.
  • the channel 13 of the gas chamber 3 is connected through a pipe 31 ( Figure 2) tothe high pressure chamber 32 within the casing 33 of the main gas valve into .which the main gas pipe 34 also opens. From the space 32 which serves as a controlling chamber for the main gas valve 38, a second space 35 of the casing 33 is separated by a diaphragm 36. This second space is connectedthrough a pipe 37 to the channel 14 of the controlling gas valve 3.
  • a plate valve 38 which is forced by a spring 39 on to its seating on a channel 40 leading to the gas consumer, for example to the main burner 51 of the geyser is mounted on the diaphragm 36.
  • a pilot lighter pipe 41 passes from the connection 17 of the controlling gas valve 3 to a pilot lighter burner 42.
  • This lighter burner consists of a casing 43, a valve 44 having a bore 45 and a liffhter nozzle 46, and a thermostat 47 the @mis of which are fixed to the burner casing by arms 48 and which is further connected to the valve 44 by arms 49.
  • the hot water generator is represented by a coiled tube 50 above a burner 51 and water is drawn oil' at the tap 52. *For the sake of simplicity, the lighter burner 42 is shown without a thermostat.
  • FIG 3 shows the arrangement when the tap 52 is closed.
  • the water pressure in both chambers 1 and 2 of the hydraulic valve is equalized by the bore 19 of the hollow shaft
  • the spring 21 forces the diaphragms 6 and 7 upwards and Ilifts the controlling gas'valve 9..
  • the high gas pressure is transmitted from the main4 pipe 34 through 32, 31', 11, 12 and 37 to the chamber 35 to equalize the pressure on each side of the diaphragm so that ⁇ the spring 39 con uently forces the main plate valve 38
  • the lighting burner 42 is o n to 1ts seating. closed, because .its valve 44 is pressed on to its seating by the cold thermostat. Gas canne' therefore, either escape from the lighting b rner 42 or from the heating burner 5l.
  • the gas hi' h pressure in the chamber 32 can consequent y force the diaphragm downwards according to the reduction 1n pressure in the controlhng lchamber 35.
  • the plate valve 38 is thereby lifted from its seating so that the main' burner 51 is provided with gas which is ignited by the lighter flame ( Figure 6).
  • the main burner of the heating arrangement for the liquid will therefore automatically be put into action as soon as water will be drawn from the apparatus when the lighter flame is burning.
  • the casing ot the controlling gas valve is closed by a diaphragm 26 in the middle of which is secured a plate valve 9 which closes a bore 27 in the artition 25.
  • a spring 29 tends to lift the plate valve 9 from its seat.
  • the plate valve 9 is provided with an edge 30 on its top which is engaged by the flattened end of the lever 23.
  • a tube 19 which projects into the water channel 5 and there forms a throttle passage for the low of water is inserted in the supporting member 8 between the diaphragms 6 and 7, the tube connecting the throttle point with the water chamber 2.
  • controlling gas valve 3 is combined with the hydraulic valve device by being arranged in the usual between the water chambers of the hydraulic valve device which are closed by diaphragms. 1t is, however, better to separate the controlling gas valve Jfrom the hydraulic valve device as shown in Figure 7 in order to ⁇ prevent water penetrating into the gas pipe in the event of one of the diaphragms being damaged.
