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.
Summary of the invention
Object of the present invention is to overcome the deficiencies in the prior art,, provide a kind of simple in structure, volume is little, can be connected with gas supply pipe easily, combustion gas output flow is stablized and gas pressure-reducing surge pipe that can regulation output pressure.
Object of the present invention is achieved through the following technical solutions:
Rotary type decompression surge pipe, body, 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; Fixed body, fixed body comprises center plectane, middle annulus and outer toroid, the internal surface of middle annulus is connected with the outer surface of center plectane, the middle outer surface of annulus and the internal surface of outer toroid are connected, the outer surface of outer toroid is threaded with the internal surface of low-pressure cavity, in outer toroid, offer multiple vents, the outer surface symmetry of middle annulus offers holding tank; Bearing, bearing is arranged between middle annulus and center plectane; Spring, one end of spring is connected with center plectane; Piston, piston is connected with the other end of spring, and spring promotes the end that piston is close to hyperbaric chamber; Vent, vent is opened on the tube wall of low-pressure cavity, and the two ends of vent are all communicated with the inner space of low-pressure cavity, and vent is between fixed body and the end of hyperbaric chamber.
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 overcomes the elastic force of spring and promotes piston moves to the direction of fixed body, when piston slips over behind the end of vent near hyperbaric chamber, combustion gas in hyperbaric chamber flows into vent, then enters low-pressure cavity by another end of vent.Now enter gaseous-pressure in low-pressure cavity lower, can normally use for user.Because vent is evenly distributed on the tube wall of low-pressure cavity, the combustion gas that enters low-pressure cavity can be evenly distributed in 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, the gas quantity in low-pressure cavity increases, and low-pressure cavity internal pressure increases, and under the internal pressure of low-pressure cavity and the acting in conjunction of spring force, piston is pushed back original position, is close to the end of hyperbaric chamber.
While needing regulation output gaseous-pressure size, pull down the present invention, utilize clamping device to clamp middle annulus by the holding tank on middle annulus, annulus in the middle of then rotating, the moving outer toroid of middle circle endless belt is rotated.Because outer toroid is threaded with low-pressure cavity internal surface, so can drive fixed body to move in the axial range of low-pressure cavity.When fixed body is during near hyperbaric chamber, spring is compressed, and combustion gas in hyperbaric chamber is more difficult to be overcome the elastic force of spring and promote piston and move to the direction of fixed body, and therefore the gaseous-pressure in low-pressure cavity is less.When fixed body is during away from hyperbaric chamber, spring is upheld, and the combustion gas in hyperbaric chamber more easily overcomes the elastic force of spring and promotes piston moves to the direction of fixed body, and therefore the gaseous-pressure in low-pressure cavity is larger.
Owing to being provided with bearing between middle annulus and center plectane, therefore, in the time adjusting fixed body position, center plectane can not rotate with middle annulus, and the position regulation of fixed body is more prone to.
Further, also comprise multiple rectangular thin slices, rectangular thin slice is connected with described center plectane and is positioned at described spring surrounding, rectangular thin slice and spring contact.
Spring, in telescopic process, may bend in the radial direction, for a long time, repeatedly several bending can cause spring to damage.For this reason, rectangular thin slice is set, rectangular thin slice is carrying out spacingly in the radial direction to spring, prevent spring bending, thereby prevents that spring from damaging because of bending.
Further, the outer surface of described piston is conical surface, and the end of described hyperbaric chamber is the conical surface corresponding with the outer surface of described piston.
Piston contacts by conical surface with the end of hyperbaric chamber, can improve sealability, 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, also comprise the rubber layer that is arranged at described hyperbaric chamber end tapered face.
Rubber layer is set, can further increases sealability.
In sum, advantage of the present invention and beneficial effect are:
1. the present invention is simple in structure, and cost is low, and volume is little and can be connected with gas supply pipe easily;
2. 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;
3. the pressure of the present invention's regulation output combustion gas easily;
4. rectangular thin slice is set, prevents spring bending, improved working life of the present invention;
5. the end of hyperbaric chamber contacts by conical surface, can improve sealability, 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;
6. rubber layer, can further increase sealability.
