Abstract

The utility model discloses a household gas pressurizer for increasing gas pressure, composed of an electric magnet, a push rod, a diaphragm and a closed chamber. With the driving of the electrical magnet, the diaphragm makes reciprocal motion to make the volume of the closed chamber increase and decrease, so as to make the gas inhaled from the air inlet, exhausted out vie the air outlet after pressurizing, and enter a gas cooker in uniform pressure after cushioning in a two-stage diffusion chamber. The gas pressurizer solves the problem of lack of gas pressure, and makes people's life convenient.

Description

The coal gas pressure-increasing machine

The utility model is a kind of pressure-increasing machine that utilizes mechanical means to increase gas pressure.

Current China is all greatly developing domestic gas in various places, it is as a kind of convenience, economic, as to clean New-type fuel has been subjected to people's popular welcome, but owing to be subjected to the restriction of economy and technical force, the situation that supply falls short of demand has appearred in coal gas, nearly all do not satisfy needs at various places coal gas, particularly at noon, evening is during usefulness gas peak, the gas pressure wretched insufficiency, even can't cook, influenced people's life.And also do not have home-use coal gas pressure-increasing machine to solve this problem at present.The utility model designs for addressing this problem.This pressure-increasing machine power consumption is few, and volume is little, in light weight, and is effective, is comparatively ideal town gas pressure-increasing machine.

The utility model is to utilize electromagnet to drive barrier film to move reciprocatingly.Barrier film makes the volume of confined chamber repeat to take place increase and decrease, and volume increases inspiration coal gas, and volume reduces to increase gas pressure, enough uses for people the back thereby can increase to pressure to low-pressure gas.

Below in conjunction with figure pressure-increasing machine is described in further detail.

Fig. 1 is a coal gas pressure-increasing machine schematic diagram.

With reference to Fig. 1, the pressure of spring (14) is less than coal gas pressure just often.Coal gas is when normal pressure, and coal gas through one-way valve (3) and (8), enters confined chamber (4) and (7) from suction tude (6), enters explosion chamber (11) and (10) through one-way valve (13) and (15), enters gas ring through outlet pipe (9).When gas pressure during less than normal pressure, one-way valve (3) and (8) are closed.At this moment, open switch, connect power supply, electromagnet (1) is started working, and produces to-and-fro motion.Barrier film (5) is made C shape with flexible materials such as ox-hide, rubber plates, is fixed on the confined chamber all around.Barrier film (5) links by push rod (2) and electromagnet (1).Under electromagnet (1) drives, also to-and-fro motion of barrier film (5).When barrier film (5) when confined chamber (4) moves, become C shape at confined chamber (4).Confined chamber (4) volume reduces, and pressure increases.Coal gas in the confined chamber (4) enters explosion chamber (11) through one-way valve (15), and after explosion chamber (11) and (10) twice buffering, coal gas is with uniform pressure inflow gas ring.At this moment, confined chamber (7) volume increases, and pressure reduces, and coal gas enters confined chamber (7) through one-way valve (8).When barrier film (5) when confined chamber (7) moves, barrier film (5) becomes O shape, confined chamber (4) volume increases, and carries out breathing process, confined chamber (7) volume is little, carries out exhaust process.Coal gas enters explosion chamber after supercharging.Explosion chamber (10) plays buffer function with (11).Has pulsating pressure after the coal gas supercharging.After entering explosion chamber, because volume increases, pressure reduces thereupon, has relaxed the impact force when confined chamber is discharged, and after two-stage explosion chamber buffering, coal gas is just to enter gas ring than uniform pressure.Push rod (2) seals with seal ring in the outlet port of confined chamber (4), and coal gas can not leaked outside, and is comparison safety therefore.

The to-and-fro motion of barrier film (5) can be provided by an electromagnet, also can make the confined chamber both sides, and an electromagnet is respectively arranged, and cooperatively interacts, and to-and-fro motion is provided.

The pressure size of coal gas pressure-increasing machine is to be regulated by the switch on the rough gas pipeline, and promptly switch leaves greatly, and pressure is big, and switch leaves little, and pressure is little.

The utility model is safe and reliable, and the life that can be convenient for people to is the effective tool that solves current gas pressure deficiency.
