Electric gas heater

Abstract: PURPOSE:To prevent a short circuit fault and also to miniaturize a heater entirely by connecting all heating tubes in a flux in parallel electrically in the heater device which posses a gas through the heating tubes and heat by an electrothermal action CONSTITUTION:Helium gas fed in a vessel 21 through an inlet 20 is heated by a heating tube 23 while passing through the heating tube 23 from an inlet chamber 22 and delivered outside from an outlet 25 by way of an outlet chamber 24 In this case, the heating tubes 23 are classified into a plural number of groups, the tube ends are welded to flanges 26, 27 to a heating tube flux at equal pitch intervals on the circumference, and each top flange 26 is hung on an end plate 28 fixed on the vessel 21 apart from the other heating tube flux 30 On the other hand, an electrode rod 29 is mounted at the center of the bottom flange 27 of each heating tube flux 30, which is connected to a three-phase AC power supply

Reduce frequent device that starts of gas heater

Abstract: The utility model discloses a reduce frequent device that starts of gas heater, including gas heater, little kitchen is precious, cold and hot water faucet and including by water flow switch A, water flow switch B, normally -closed solenoid valves, the normally open solenoid valve, the control circuit that time relay and auxiliary relay constitute, gas heater and little kitchen treasured are intake to hold and are connected with water pipe, gas heater goes out the water end (W. E. ) and connects little kitchen treasured, cold and hot water faucet is connected to the precious play water end (W. E. ) in little kitchen, water flow switch A and normally -closed solenoid valves set up respectively in the gas heater outlet pipe on the road, water flow switch B sets up respectively on the running water water intake pipe who is connected with little kitchen treasured with the normally open solenoid valve, water flow switch B inductive head and time relay electric connection, time relay and auxiliary relay electric connection, auxiliary relay again respectively with normally -closed solenoid valves, normally open solenoid valve and water flow switch A electric connection, the utility model discloses can reduce the number of times that gas heater frequently opened, protection water heater, water economy resource.

Automatic pressure boost hot water recycle device and application system thereof

Abstract: The utility model provides an automatic pressure boost hot water recycle device and application system thereof relates to the gas heater field. This automation pressure boost hot water recycle deviceis applied to automatic pressure boost hot water recycle device's application system. Automatic pressure boost hot water recycle device's application system includes water heater, total inlet tube, hot -water line, cold water pipe and a plurality of water consuming point. The water heater includes cold water inlet pipe and hot water exit tube. The controller is used for starting according to the start -up flow rate control booster pump of real -time flux and booster pump, and wherein, start -up flow rate is the hot water flow threshold values of booster pump after opening, the controller stillis used for cutting out with circulation pipeline's circulation pressure control booster pump according to real time pressure, and wherein, the circulating pressure is circulation pipeline's standardpressure.

Double-air-supply nozzle

Abstract: The invention discloses a double-source gas nozzle structure for gas heater, which is aimed at solving the problem that no appropriate nozzle can be chosen for the same gas heater using alternative gas in the prior rapid development of gas sources. The double-source gas nozzle structure is characterized in that: the gas nozzle structure is provided with a low calorific value gas inlet and a nozzle for calorific value gas and a high calorific value inlet and a nozzle for high calorific value gas; meanwhile, the invention discloses a related aperture ratio, thereby the market demand that one nozzle is used for two gases can be solved. The double-source gas nozzle structure for gas heater has the advantages of simple structure, convenient manufacture, installation and use.

Fireplace with 1/f fluctuation

Abstract: PURPOSE:To ensure that a heater such as a gas heater appears wavering similarly to a natural flame to make people feel comfortable as well as warm, by disposing an incandescent lamp for lighting, which is covered by ground glass on the face side, at an upper position on the front side of a burner, and forming a power supply for the lamp by superimposing a DC bias voltage on a 1/f fluctuation voltage. CONSTITUTION:A burner, e.g. a gas burner 3 is placed on the lower side in a firebox 5, and a plurality of incandescent lamps 2 are placed on the room side, with a partition wall 10 between the burner 3 and the lamps 2 and with a sheet of ground glass 11 disposed at an upper position on the front side of the lamps 2. A DC voltage is applied between both ends of solid carbon 14, and a minute fluctuating current with 1/f spectrum generated at the ends of the solid carbon 14 is passed through a capacitor 16 to extract the fluctuation as a 1/f fluctuation voltage 17. A power supply 19 for each of the lamps 2 is produced by superimposing the 1/f fluctuation voltage to a DC bias voltage. The lamps 2 are supplied individually with the 1/f fluctuation voltages, to show variations in illuminance, thereby producing an effect similar to a wavering flame of burning firewood, so that the people in the vicinity of the fireplace can peel comfortable and warm.
