Description
Technical field
The present invention relates to combustion gas transportation art, relate in particular to combustion gas feedway.
Background technique
Combustion gas needs to keep high pressure in course of conveying, and in the time that user side uses, need to reduce gaseous-pressure.Current, in order to reduce gaseous-pressure at user side, reduction valve is set on gas supply pipe conventionally.Existing structure of relief pressure valve complexity, manufacture cost is high, and reduction valve volume is larger, cannot in small space, install.
Existing reduction valve, for example publication number is the disclosed a kind of high pressure gas reducing valve of the Chinese patent application of " 102052495A ", rock gas is flowing into from inlet end, after the mechanism of decompressor when entering from the direction under upper the cavity being communicated with outlet side, now rock gas can be ejected on cavity wall, the gas flow that causes entering outlet side is confused, very easily causes flowed fluctuation, and while causing user to use, flame status is unstable.
Meanwhile, existing reduction valve, adopts spring as force mechanism, and spring length is longer, causes existing reduction valve volume large, and adopts size less spring, and enough elastic force cannot be provided, and causes the gaseous-pressure cannot the available degree of the value of being attenuated.
Summary of the invention
Object of the present invention is to overcome the deficiencies in the prior art, provides the one can be simple in structure, and volume is little, combustion gas output flow stable and can be connected easily miniature relief pipe with gas supply pipe.
Object of the present invention is achieved through the following technical solutions:
Miniature relief pipe, comprises body, and body two ends are provided with connecting thread, and the space in body is made up of hyperbaric chamber and low-pressure cavity; The internal diameter of hyperbaric chamber is less than the internal diameter of low-pressure cavity; Sheet rubber, sheet rubber is arranged in low-pressure cavity and with the internal surface of low-pressure cavity and is connected, and sheet rubber contacts with the end of hyperbaric chamber, and the contacting point, end of sheet rubber and hyperbaric chamber evenly offers multiple air outlet holes, and the central position of sheet rubber offers arc groove; Receiving cavity, arranges and hyperbaric chamber one end near sheet rubber, ball sealer, and ball sealer is placed in arc groove, and ball sealer is pressed in receiving cavity by sheet rubber and is close to the transition position of receiving cavity.
Working principle of the present invention is as follows:
The two ends of body are connected with fuel gas transportation pipeline.In the time that user side need to use combustion gas, gas quantity in low-pressure cavity reduces, low-pressure cavity internal pressure reduces, the now combustion gas in hyperbaric chamber promotes ball sealer, ball sealer promotes sheet rubber, sheet rubber distortion, ball sealer departs from the transition position of receiving cavity, and the combustion gas in hyperbaric chamber is flowed out from the gap of the transition position of ball sealer and receiving cavity.Due to sheet rubber bending deflection, the end of air outlet hole departs from the end of hyperbaric chamber in open state, and the combustion gas of flowing out from the gap of the transition position of ball sealer and receiving cavity enters low-pressure cavity by air outlet hole.Now enter gaseous-pressure in low-pressure cavity lower, can normally use for user.Because air outlet hole is uniformly distributed, the combustion gas that enters low-pressure cavity from air outlet hole can be evenly distributed on low-pressure cavity, and combustion gas output flow is stable, has avoided the confused problem of fuel gas flow, can not cause the unsettled situation of flame status to occur.
In the time that user does not use combustion gas, gas quantity in low-pressure cavity increases, low-pressure cavity internal pressure increases, under the acting in conjunction of the internal pressure of low-pressure cavity and the elastic force of sheet rubber, sheet rubber return is also close to the end of hyperbaric chamber, air outlet hole is got back to closed state, and ball sealer is pressed in receiving cavity by sheet rubber and is close to the transition position of receiving cavity, stops the combustion gas in hyperbaric chamber to enter low-pressure cavity.
The present invention adopts sheet rubber to substitute spring, effectively reduces the volume of relief pipe.
Arc groove is set, can positions ball sealer, while preventing that the present invention is under level, ball sealer drops downwards under the effect of gravity.
Further, described transition position is conical surface.
Ball sealer coordinates with conical surface, can improve sealability, further prevents in the time that user does not use combustion gas, and the combustion gas in hyperbaric chamber enters in low-pressure cavity and causes user to start by the excessive problem of gas moment gaseous-pressure.
Further, the internal surface of described low-pressure cavity offers annular groove, and the edge of described sheet rubber is arranged in annular groove.
Annular groove is set, and sheet rubber can be arranged in annular groove easily, has improved packaging efficiency of the present invention.
Further, also comprise limited ring, limited ring is arranged at the internal surface of described low-pressure cavity, and limited ring and described sheet rubber are away from an end in contact of described hyperbaric chamber.
Limited ring is set, prevents that sheet rubber from, in BENDING PROCESS, departing from from annular groove.
Further, the surrounding arc transition of described limited ring.
The surrounding arc transition of limited ring, can prevent that sheet rubber limited ring in BENDING PROCESS from scratching.
Further, the joint arc transition of the internal surface of described annular groove and described low-pressure cavity.
Sheet rubber is in the time of bending, and sheet rubber is arranged in the position of annular groove can be stressed and be close to the cell wall of annular groove, therefore by the joint arc transition of the internal surface of annular groove and low-pressure cavity, can prevent that the joint of the internal surface of annular groove and low-pressure cavity from scratching sheet rubber.
In sum, advantage of the present invention and beneficial effect are:
1. the present invention adopts sheet rubber to substitute spring, effectively reduces the volume of relief pipe;
2. the present invention is simple in structure, and cost is low and can be connected with gas supply pipe easily;
3. it is confused that the present invention can not cause fuel gas flow, and combustion gas output flow is stable, avoided the unsettled situation of flame status to occur;
4. ball sealer coordinates with conical surface, can improve sealability, further prevents in the time that user does not use combustion gas, and the combustion gas in hyperbaric chamber enters in low-pressure cavity and causes user to start by the excessive problem of gas moment gaseous-pressure;
5. annular groove is set, and sheet rubber can be arranged in annular groove easily, has improved packaging efficiency of the present invention;
6. the surrounding arc transition of limited ring, can prevent that sheet rubber limited ring in BENDING PROCESS from scratching;
7. by the joint arc transition of the internal surface of annular groove and low-pressure cavity, can prevent that the joint of the internal surface of annular groove and low-pressure cavity from scratching sheet rubber.
