Abstract

The utility model relates to a gaseous fuel pressurizer which is used for pressurizing household gaseous fuel. A pressurizing pump with a gas entering and a gas discharging one-way valves pumps gaseous fuel into a gas storage barrel, when a pipeline system is short of pressure or a canned gas source has little residual gas, the gaseous fuel can be pressurized in the gas storage barrel, and then a gaseous fuel apparatus is supplied with gas through a pressure reducing valve.

Description

Gaseous fuel pressurizer

The utility model relates to the supercharging device that family uses combustion gas.

Use combustion gas to act as a fuel universal day by day.Pipe gas can produce pressure oscillation or insufficient pressure once in a while using the peak period, causes the flame instability of kitchen range or flame too little, and gas heater can stop working because of pressure transient.Use canned combustion gas, in jar residual air not for a long time, its insufficient pressure causes kitchen range flame too little or basic point is missing of ignition, residual air can't be utilized in jar, can only waste.

The purpose of the utility model is the pressurizer of gas that provides a kind of family expenses, to guarantee still can normally to use gas appliance when bleed pressure deficiency or the pressure transient fluctuation.

Described pressurizer of gas has a force (forcing) pump, and its air inlet is communicated with source of the gas by breather check valve, and its exhaust outlet is communicated with gas receiver by exhaust check valve, and gas receiver can connect pressure-reducing valve and be communicated with gas appliance.

The utility model is communicated with between source of the gas and gas appliance, and is stable and when being in normal pressure value when bleed pressure, combustion gas can be smoothly inlet and outlet check valve by force (forcing) pump enter gas receiver, and to the gas appliance air feed.When pipeline source of the gas hypotony or canned source of the gas residual air not for a long time, with force (forcing) pump combustion gas is squeezed in the gas receiver and can guarantee with pressure stable to the gas appliance air feed.

Fig. 1, the described device cutaway view of employing manual pump;

Fig. 2, the described installation drawing of employing foot pump (or electrodynamic pump);

Embodiment one, referring to Fig. 1,

Force (forcing) pump 2 is contained in the gas receiver 1, and piston 8 and piston rod 3 are arranged in the pump barrel 5, and the epicoele of force (forcing) pump 2 is communicated with air inlet 4, and this air inlet connects source of the gas, and the cavity of resorption of force (forcing) pump 2 is communicated with gas receiver 1 by exhaust check valve 7.On the piston 8 different diameter hole is arranged, the mid-ball in hole constitutes breather check valve 6.Also there is different diameter hole pump barrel 5 bottoms, and the mid-ball in hole constitutes exhaust check valve 7.Back and forth promote piston rod 3 with hand, the combustion gas of source of the gas is pumped in the gas receiver 1, gas receiver 1 has air discharge cook 9, and it is communicated with gas appliance after connecing pressure-reducing valve again.

Embodiment two, referring to Fig. 2,

Force (forcing) pump 2 has spill housing 10, its bottom is driven into, exhaust outlet, be furnished with breather check valve 6 and exhaust check valve 7 on the inlet and outlet pipeline respectively, hinged pedal 14 on the housing 10, it has boss to stretch in the housing 10, and the periphery of diaphragm 11 is fixed on housing 10 concave bottom portions, and diaphragm 11 middle parts are fixed on pedal 14 middle parts, the non-hinged end of pedal 14 has stage clip 13 to be contained between pedal 14 and the housing 10, and pedal 14 can be finished suction repeatedly, exhaust process pumps into combustion gas in the gas receiver 1 with pin.Pedal 14 is an irony, dress electromagnet 12 on the housing 10 of its non-hinged end, and its make pulse power supply can make irony pedal 14 move back and forth, and finishes suction, exhaust process.

Claims
