Abstract

The utility model discloses a household gas pressurizer used for increasing gas pressure, composed of an electromagnet, an air cylinder, a piston, a diffusion chamber and a circuit switch, wherein, the electromagnet provides dynamic force for driving the piston to move back and forth in the air cylinder. Thus, the gas is sucked in, the pressure is increased, and the gas is exhausted. The gas in uniform pressure is supplied to people for burning through two-stage diffusion buffer.

Description

Gas pressurizer

The utility model is to utilize piston to increase the machinery of gas pressure.

In people's life, coal gas is welcome fuel, and its economic cleaning has brought convenience for people's life.But owing to be subjected to the restriction of economy and technical force, coal gas in all parts of the country does not nearly all satisfy needs, particularly at noon, evening, the gas pressure wretched insufficiency influenced people's life during usefulness gas peak.And also do not have home-use coal gas pressure-increasing machine to solve this problem in the market.Though the coal gas pressure-increasing machine of utility model application special issue 88204119.3 can address this problem preferably.But also there are some shortcomings.The barrier film fatiguability damages.The air displacement that makes a round trip is few.The utility model can overcome above-mentioned shortcoming preferably, is comparatively ideal coal gas pressure-increasing machine.

The utility model is to utilize electromagnet to drive reciprocating motion of the pistons, discharging after the coal gas boost pressure in the cylinder, enough uses for people the back thereby can increase to pressure to low-pressure gas.

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

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

Fig. 2 is flexible contact disk schematic representation;

Fig. 3 is that circuit disconnects schematic representation;

With reference to Fig. 2.Flexible contact disk is a V-arrangement.The A face is a conductor.The B face is an insulator.With reference to Fig. 1, behind the connection power supply.Electric current is through contact disk (7), flexible contact disk (5) the A face of active contacting plate (8), cross bar (4), skate (3), fixed contact piece (2).Form the loop by electromagnet (1).Electromagnet energising back produces magnetic force.Transverse slat (21) is inhaled to oneself.At this moment cross bar (4) also is moved to the left.Driving active contacting plate (8) by flexible contact disk (5) simultaneously is moved to the left.At this moment circuit is unimpeded all the time.After active contacting plate (8) moves to the end.The plate (23) that is fixed blocks.At this moment circuit is still unimpeded.Transverse slat (21) continues to be moved to the left.Flexible contact disk (5) is subjected to the resistance of pulling force and active contacting plate (8).Active contacting plate (8) will force flexible contact disk (5) to move inwards along the slope of flexible contact disk (5) A face.Spring (6) is compressed.With reference to Fig. 3.After active contacting plate (8) slides into flexible contact disk (5) C point.Flexible contact disk (5) is outwards moved by the thrust of spring (6).The B that makes flexible contact disk (5) is facing to active contacting plate (8).Because flexible contact disk (5) B face is an insulator.At this moment circuit is cut off.Magnetic force disappears.Active contacting plate (8) is under the effect of spring (9) simultaneously.Move right and get back to initial position.At this moment transverse slat (21) also moves right under the effect of spring (22).When flexible contact disk (5) B face and active contacting plate (8) when contacting.Circuit is access failure still.At this moment transverse slat (21) continues to move right.Flexible contact disk (5) B face slope is under pressure.Force flexible contact disk (5) to move inwards.Pressure spring (6).After active contacting plate (8) is by the C point.Flexible contact disk (5) is under the effect of spring (6).Outwards move.The A face of flexible contact disk (5) is by active contacting plate (8).At this moment electric current is connected.Repeat said process.Electromagnet (1) will to-and-fro motion.Contact disk (7) all contacts with active contacting plate (8) all the time.Fixed contact piece (2) also contacts with skate (3) all the time.

With reference to Fig. 1.Piston rod (12) connects with transverse slat (21).When the electromagnet to-and-fro motion.Piston is to-and-fro motion also.The pressure of spring (14) is less than the coal gas normal pressure.When gas pressure just often.Coal gas enters cylinder through passage (11), (10), (16).Discharge by passage (17), (19) respectively.Use for people.When coal gas during less than normal pressure.Open switch.Connect power supply.The electromagnet to-and-fro motion.Piston is to-and-fro motion also.When piston is moved to the left.The pressure on piston the right reduces.Make the valve-closing of passage (17).Coal gas is by passage (16).Unseat the valve (15) enters the right cylinder.Piston left side pressure increases simultaneously.Make the valve-closing of passage (10).Back down the valve of passage (19).Coal gas enters explosion chamber (18) by passage (19).When piston moves right.The valve-closing of passage (19).The valve of passage (10) is opened.Coal gas enters chamber, a piston left side.The piston right ventricle closes valve (15) because pressure increases.The valve of passage (17) is opened.Carry out exhaust process.After coal gas enters explosion chamber (18).To use for the user with uniform pressure through two-stage diffusion buffering.

In cylinder port seal ring (20) sealing is arranged.Prevent that coal gas from leaking.

The utility model is safe and reliable.It is the effective tool that solves the gas pressure deficiency.
