Gas heater with pipeline emptying device

Abstract: The utility model discloses a gas heater with pipeline emptying device, including the heat exchanger who has inlet tube and outlet pipe, be provided with pipeline emptying device on the outlet pipe, pipeline emptying device includes the control unit, air pump, first stop valve and second stop valve, the blast pipe of air pump with the outlet pipe intercommunication, the second stop valve sets up in the blast pipe, first stop valve setting is in in the outlet pipe, and be located the gas vent of blast pipe with between the heat exchanger, outlet pipe and shower head intercommunication The utility model discloses a gas heater, through setting up pipeline emptying device, the water in heat exchanger's delivery port to the shower head section pipeline is blown out from the shower head under gas pressure's effect, retains so much cold water when having avoided next uses in the pipeline and leads to the fact resource and energy waste, has avoided water waste, prevent with the hot water blowback among the heat exchanger to the water pipe in, protect water pipe

Catalytic start-up preheater for cars

Abstract: The utility model relates to a catalyzing and starting pre-heater used for an automobile, which relates to a starting pre-heater used for an automobile. The catalyzing and starting pre-heater solves the problems of complex assembly and tedious use in the prior automobile warming apparatus, and overcomes the defects that the electrical heating pre-heater used for automobiles can not be used under a condition of unavailable power or a circumstance of inconvenient power supply. A circulating waterway is formed by a vehicle water tank, a water pump and a heating chamber of a catalytic gas heater; three temperature signal acquisition terminals of a controller are connected with the temperature signal output end of a first temperature sensor, a second temperature sensor and the third temperature sensor respectively, the heating and the controlling terminal of the controller is connected with the controlled terminal of the igniter of the catalytic gas heater, the water source controlling terminal of the controller is connected with the power supply controlled terminal of a water pump, and the air supply controlling terminal of the controller is connected with the controlled terminal of an electromagnetic valve; and the air outlet of an air supply component is connected to a burner air inlet of the catalytic gas heater. The utility model has the advantages that no external power is required, dismantling is not required after installation, the stability is high, and long term use can be performed.

Outdoor gas heater

Abstract: The invention relates to an outdoor gas heater which is characterized in that an infrared mesh enclosure is arranged in a glass tube above a gas chamber, and an infrared generator is arranged above the glass tube; further, the infrared generator is a connecting piece consisting of a cylinder-shaped stainless steel mesh enclosure and a stainless steel fire seal plate transversally arranged in the mesh enclosure, wherein the bottom end of the stainless steel mesh enclosure is provided with a circular ring, the top end is provided with a concave seal plate and the peripheric circular wall is provided with mesh openings; further, the infrared mesh enclosure is a column-shaped stainless steel mesh enclosure. The invention has the advantages that two principles of air heat convection and infrared radiation is adopted to design the outdoor gas heater, thus the heat exchange rate of the outdoor gas heater is improved.

Gas supply system and adopt its gas -cooker and gas heater

Abstract: The utility model relates to a gas equipment technical field especially relates to a gas supply system and adopt its gas -cooker and gas heater. Gas supply system includes gas pipeline, air piping and air feed controlling means, and this air feed controlling means sets up on gas pipeline and/or on the air piping for the control gas of correspondence and/or the supply volume of air. The gas -cooker and the gas heater that adopt above -mentioned gas supply system are still provided simultaneously. The utility model discloses an air feed controlling means controls the supply volume of gas and/or air, has realized the regulation to gas and air ratio, and then has satisfied the normal combustion operating mode of different air supplies.
