Description

Gas Combustion booster

The utility model relates to a kind of gas pipeline and carries supercharging device, and this pressurized machine is made up of suction tude, housing, steam outlet pipe, battery case etc.

A kind of " cutting off----balanced combination gas pressure regulating valve " disclosed in CN2126724Y, this pressure regulator valve comprises main valve, pressure governor, cut-off valve, the cut-out balanced component that is equipped with in the combination brake switch and proporting, connecting rod assembly and push-rod assembly, cut off in the balanced component and also comprise valve A, comprise valve B in the push-rod assembly, this combination brake switch and proporting has the cut-out equilibrium function, and improved the valve input and pressed influence and the valve precision of fluctuation the output pressure, can be widely used in gas pressure regulation occasions such as coal gas, but the pressurized effect of this valve is not obvious, be mainly used in and adjust the influence of fluctuations that the input pressure is pressed output, and structure is very complicated, and technological level is had relatively high expectations.

The utility model is made of turnover tracheae, housing, battery case and motor, impeller, garden awl guide, is characterized in that based on housing the turnover tracheae is linearly established at two; Also steam outlet pipe can be placed suction tude one side, the turnover tracheae is vertical configuration, and sealed electric-motor is set in the housing, and machine shaft is coaxial with the garden cylinder shell; Another kind of mode places motor outside the square housing, its rotating shaft is stretched in the housing facing to suction tude, impeller is installed on the machine shaft, when adopting aforementioned first kind of structure, the necessary strict seal of motor, the seal closure made from metal and plastic insulating layer double layer construction material seals, and ignites combustion gas to prevent electrical spark; When adopting second kind of structure, but the salable also blow-by of motor, but machine shaft stretches into the housing place, needs the double-layer seal circle to carry out strict seal.First kind of mode motor is fixed on the housing by fixed support, fixed support is three hollow posts, motor is stabilized in housing central authorities, and motor terminal then passes the fixed support hollow space and introduces the battery case wiring terminal, can avoid lead and contact directly to contact with combustion gas like this; Second way motor is fixed in outside the housing by fixed support, and its terminal is directly introduced in the battery case near motor one side.Impeller is arranged in housing air inlet pipe end, impeller is the pot body shape member of a plurality of curved surfaces of tool or spiral blade, garden awl guide and housing combine as a whole, place steam outlet pipe one end, awl mouth and steam outlet pipe conducting, the former mode is that guide is bored facing to impeller and suction tude in the garden, and latter's mode is guide to be bored in the garden place impeller one side, and above-mentioned member is all available engineering plastics injection moulding except that motor.When driven by motor impeller high speed rotating, blade stirs combustion gas and flows to steam outlet pipe one end fast, can reach the purpose of boosting, and simultaneously, its cross section of awl guide, garden is pre-large post-small, and airspeed is changed from small to big, and can further play the effect of boosting.The heat that swiftly flowing gas is sent in the time of also can be with the work of motor and impeller is taken away, and plays air-cooled effect, and power supply adopts common batteries or the Ac after the transformation rectification, and battery case is provided with the interchange jack.

Advantage of the present utility model is: adopt the direct supercharging of electric motor with vane wheel, avoided the unconspicuous defective of prior art pressurized effect and this apparatus structure simple, technological requirement is not high, and cost is low.Adopt simple knot members such as housing, garden awl guide, battery case, household gas range is processed in the injection moulding of available engineering plastics one, and the accessory utilization of water heater is convenient, flexible.
