Abstract
The invention discloses a gas pressure stabilizing system, which comprises a high pressure gas source, at least one first-stage pressure reducing valve and a dehydrator, wherein a plurality of first-stage pressure reducing valves are connected in turn, and are provided with gas outlets. Compared with the common gas pressure stabilizing system, the gas pressure stabilizing system removes water in a gas source through the dehydrator, so that the water content in the gas source in the transmission process is greatly reduced, problems that the mechanical accuracy of metal mechanical structure equipment or molds is easily influenced, metal corrosion is easily caused and the sensing accuracy of a sensor in the gas pressure stabilizing system can be influenced due to droplet seepage of the equipment or the molds caused by water-containing gas transmission in the prior art are avoided, and the dryness and accuracy of the equipment or molds are ensured. In addition, when the gas source subjected to dehydration is applied to an extruder, because the gas source does not contain water, sponge foam cannot absorb moisture due to the water, and the pressure of the gas pressure stabilizing system is stably supplied; therefore, the sponge foam is uniformly distributed and uniformly molded.
Description
Technical field
The present invention relates to a kind of gas voltage-stabilizing system, belong to the gas transmission apparatus field.
Background technique
When real gas is manufactured; The modes of canned pressurized gas that adopt realize the encapsulation to gas more; Pressurized gas after encapsulation in use; Be not the gas that all occasions all need set canned pressure; Usually required pressure condition is less than canned pressure; At this moment corresponding gas stable-pressure device just need be set comes gas pressure is regulated; Make gas pressure reach necessary requirement through adjusting, exactly because also the demand makes gas voltage-stabilizing system and voltage stabilizing technique be widely adopted.
Said system and technology also are widely used in auto industry; Such as the widely used auto parts machinery of auto industry is rubber seal; Rubber seal is many on the automotive door limit and be equipped with in the case and use; When it uses; Single dependence rubber seal can't be realized its sealing property effectively; So the cellular rubber bubble need further be set; Thereby by be provided with cellular rubber bubble realized the rainy day get into the automotive door limit and be equipped with in the case rainwater by the cellular rubber bubble fully buffering absorb; And be unlikely to, thereby guaranteed that rubber seal can effectively seal because a large amount of infiltrations of rainwater make the seal sealing be affected.
When realizing the above-mentioned functions of cellular rubber bubble; Necessarily requiring the sponge bubble to have uniform sponge bubble as much as possible distributes; This has just proposed a requirement to the extruder of sponge bubble; Promptly must have sufficiently stable pressure, can guarantee in the internal stability pressure environment that so just sponge steeps even extruding and moulding.So extruder must dispose the even extruding and moulding that stable gas voltage-stabilizing system just can be realized the cellular rubber bubble.
In the prior art; The gas voltage stabilizing is normally installed pressure regulator valve between gas input and output pipeline; Reach the purpose of gas voltage stabilizing through the pressure of regulating input gas; Such as just disclosing a kind of decompression voltage-stabilizing system among the Chinese patent document CN2582036Y; This system comprises high-pressure air source; Reduction valve; Gas holder; Pressure gauge; Parts such as throttle valve; The gas that high-pressure air source discharges is realized the release to pressure behind reduction valve; Thereby obtain the gas of lower pressure; Afterwards with the gas storage of lower pressure in gas holder; Make to keep a constant gas pressure in the gas holder, thereby guaranteed the voltage stabilizing output state of gas system.
Prepare in the process at gas; In view of the preparation environment all is conventional environment; Do not carry out environment and remove water treatment; So all contain moisture in the gas for preparing to a certain extent; Above-mentioned pressurized gas after canned contain moisture too after decompression output; These moisture can ooze out through the outlet of each equipment in the process of gas delivery, thereby the globule occurs; In addition, also may ooze out the globule through the last mould part of supplying with of source of the gas; The said equipment or mould are metal mechanical structure, and oozing out for a long time of the globule is easy to cause corrosion of metal, influences the precision of mechanical structure, also can have influence on the sensing accuracy of sensor in the gas voltage-stabilizing system simultaneously.
The most key is that above-mentioned source of the gas with moisture is easy to owing to water function when being applied to extruder, makes that the sponge that causes extruding soaks the reduction of type quality owing to sponge is steeped moisture absorption and directly influences the even distribution that sponge is steeped.
Summary of the invention
Technical problem to be solved by this invention is a pressure-stabilized air source of the prior art owing to contain moisture in the pressurized gas, and moisture causes mechanical structure precision and sensor senses precision to be affected after decompression, oozing out through equipment easily; Because also making easily, the existence of moisture directly influences the even distribution of sponge bubble because sponge is steeped moisture absorption simultaneously; The sponge that causes extruding soaks the type quality and reduces, and then provides a kind of and have except that water function, can guarantee the gas voltage-stabilizing system that the sponge bubble is evenly extruded.
