Abstract
The utility model discloses a gas flow or pressure adjustment device. The device comprises a main pipeline and a gas backflow pipeline. An inlet valve, a gas compressor and an outlet valve are sequentially arranged in the main pipeline. The gas backflow pipeline is provided with an adjusting valve, and connected with the gas compressor in parallel on the main pipeline. According to the gas flow or pressure adjustment device provided by the utility model, the gas backflow pipeline is used for adjusting the air pressure of the main pipeline to keep the air pressure of the main pipeline to be uniform and stable, thereby preventing local overlarge air pressure of the pipeline, and ensuring the transmission safety of the pipeline; besides, the adjusting valve is adopted in the gas backflow pipeline to control the flow of gas, and compared with control valves with precise control components, such as gas flow controllers, gas flow adjusting valves, etc., the adjusting valve has higher adaptability for the gas flowing therethrough, being suitable for gas transmission applications in a wider range.
Description
Technical field
The utility model belongs to gas flow or pressure regulation technology field, and particularly one is applicable to quantity-produced gas flow or pressure conditioning equipment.
Background technology
In gas industry; often using diaphragm type compressor to obtain gases at high pressure carries toward subsequent technique; but; in actual production; it is required that molding machine top hole pressure is often greater than subsequent technique, if compressor shutdown is carried out to pressure adjusting, can mix the purity of air impact product; increase manual operation, and easily cause security incident.Therefore, often by regulating pipeline gas flow or pressure, guarantee that rear produces continuously at present.
At present common control flow or the technology of pressure have frequency converter, by parameter, control compressor rotary speed are set and can realize predetermined amount of flow; Also can adopt gas flow controller, gas flow regulating valve etc. to control gas flow, these class methods easily cause manifold pressure to increase, and because gas can be with the impurity such as particle, moisture, especially for some poisonous corrosive gass, easily cause the damage of frequency converter, controller and valve, more serious meeting causes obstruction, leaks, and has serious potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of gas flow or pressure adjustment assembly are provided, and the pressure that can realize the fixing gas of flow regulates, simple and reasonable, easy to operate, safe and reliable, the system that can realize is produced continuously, also can be used for poisonous corrosive gas.
In order to solve the problems of the technologies described above, the utility model provides a kind of gas flow or pressure adjustment assembly, comprise main pipeline and gas reflux line, on described main pipeline, be sequentially with admission valve, gas compressor and outlet valve, described gas backstreaming pipeline is provided with variable valve, and described gas backstreaming pipeline and described gas compressor are parallel on described main pipeline.
As the improvement of such scheme, described variable valve rear is in series with retaining valve.
As the improvement of such scheme, described retaining valve allows the gas that flows to described retaining valve direction from described variable valve to pass through, and forbids that the gas that flows to described variable valve direction from described retaining valve passes through.
As the improvement of such scheme, described gas compressor is diaphragm type compressor.
As the improvement of such scheme, between the above admission valve of described main pipeline and described gas compressor, be provided with air strainer.
As the improvement of such scheme, the described main pipeline pipeline section straight line in parallel with described gas backstreaming pipeline connects, and described gas backstreaming pipeline is inverted U structure.
Implement the utility model, there is following beneficial effect:
The utility model regulates the air pressure of main pipeline by gas backstreaming pipeline, and it is uniform and stable that the air pressure of main pipeline keeps, and there will not be the local excessive phenomenon of pipeline air pressure, guarantees the safety that pipeline is carried; Described gas backstreaming device for cleaning pipeline overregulates the flow of valve control gas simultaneously, the inner operation valve that has accurate control part such as gas flow controller, gas flow regulating valve relatively, the gas of flowing through is had to larger adaptability, meet gas widely and carry occasion.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of gas flow of the utility model or pressure adjustment assembly.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model embodiment provides a kind of gas flow or pressure adjustment assembly, comprise main pipeline 1 and gas reflux line 7, on described main pipeline 1, be sequentially with admission valve 2, gas compressor 3 and outlet valve 4, described gas backstreaming pipeline 7 is provided with variable valve 5, and described gas backstreaming pipeline 7 is parallel on described main pipeline 1 with described gas compressor 3.
It should be noted that, the utility model regulates the air pressure of main pipeline 1 by gas backstreaming pipeline 7, and it is uniform and stable that the air pressure of main pipeline 1 keeps, and there will not be the local excessive phenomenon of pipeline air pressure, guarantees the safety that pipeline is carried; Described gas backstreaming pipeline 7 is controlled the flow of gas by variable valve 5 simultaneously, the inner operation valve that has accurate control part such as gas flow controller, gas flow regulating valve relatively, the gas of flowing through is had to larger adaptability, meet gas widely and carry occasion.
Preferably, described variable valve 5 rears are in series with retaining valve 6.
It should be noted that, described gas compressor 3 job insecurities on main pipeline 1, may cause the front and back end air pressure of the described gas compressor 3 on described main pipeline 1 unstable, described retaining valve 6 can prevent that gas from directly flowing to outlet valve 4 from described gas backstreaming pipeline 7.
Preferably, described retaining valve 6 allows the gas that flows to described retaining valve 6 directions from described variable valve 5 to pass through, and forbids that the gas that flows to described variable valve 5 directions from described retaining valve 6 passes through.
Preferably, described gas compressor 3 is diaphragm type compressor.
It should be noted that, described diaphragm type compressor has good sealing, is especially applicable to the compression with impurity or poisonous corrosive gas.
Preferably, the utility model the second embodiment, is with the first embodiment difference, between described main pipeline 1 the above admission valve 2 and described gas compressor 3, is provided with air strainer (not shown in FIG.).
It should be noted that, described air strainer can fall the contaminant filter passing in gas, makes to pass into gas in described main pipeline 1 and described gas backstreaming pipeline 7 purer, protects ducted equipment.
Preferably, the described main pipeline 1 pipeline section straight line in parallel with described gas backstreaming pipeline 7 connects, and described gas backstreaming pipeline 7 is inverted U structure.
It should be noted that, described main pipeline 1 straight line connects, and makes the air pressure loss in pipeline reduce to minimum; The described gas backstreaming pipeline 7 in parallel with it is inverted U structure, forms the tributary of described main pipeline 1 in its structure, and structure is more roundabout, coordinates the effect that regulates described main pipeline 1 pressure of playing with described gas control valve 5.
