Description
Technical field
It is used for the flow regulator of low flow rate liquid or gas the utility model relates to a kind of, was adjusted with realizing
Stability of flow changes in journey, will not occur zigzag bounce, be adjusted to certain flow point quick and precisely, and flow output is stable after regulation.
Background technology
The regulation of current micro-, low flow rate liquid or gas is to use small-bore needle-like stop valve, and as shown in Figure 1, it leads to
Overregulate the openings of sizes of valve port to adjust flow, although can play a part of adjusting flow, but during adjustment occur
Flowed fluctuation is larger, and flow can form zigzag fluctuation, it is difficult to accurately be adjusted to some flow point, adjusts time-consuming, laborious,
Flowed fluctuation situation, instability of flow also occurs when being adjusted to some flow point, it is impossible to fully meet use requirement.
Such as to flow 0.3L/H≤Q≤400L/H small flowmeter instrument carry out standard detection when, it is necessary to in pipeline
Low discharge be precisely controlled, it is desirable to adjust valve regulation flow in process steady change, fluctuation bounce should not occur, Flow-rate adjustment arrives
Should quick and precisely during certain required test point flow, the flow after adjustment should keep precise and stable flowing, otherwise influence detection essence
Degree.Meanwhile, adjust easy to operate, shortening regulating time as far as possible is short, to improve operating efficiency.
Utility model content
The purpose of this utility model is to provide a kind of manufacture simplicity, easy for operation, stable in regulation flow in process
Change, can quickly be adjusted to some flow point, output flow stable micro-, control valve for small flows device after adjustment.
The utility model includes influent stream tube of pressure-stabilizing 1, goes out to flow tube of pressure-stabilizing 2, is offered on influent stream tube of pressure-stabilizing 1 into flow tube
10, outflow tube 20 is offered on going out to flow tube of pressure-stabilizing 2, is connected in influent stream tube of pressure-stabilizing 1 with going out to flow between tube of pressure-stabilizing 2 provided with least one
Pipeline 3, is provided with valve 4 on connecting pipeline 3.
The utility model structure list, manufacture is easy.
Medium is entered in influent stream tube of pressure-stabilizing 1 by the influent stream mouth of pipe 10 when using, because the volume of influent stream tube of pressure-stabilizing 1 is big, can be with
Stable, pressure stabilization function is produced to entering the medium in influent stream tube of pressure-stabilizing 1, so that the medium of outflow influent stream tube of pressure-stabilizing 1 is also protected
Keep steady pressure, steady flow；Similarly, since go out to flow the volume of tube of pressure-stabilizing 2 greatly, can be to entering out the medium in miscarriage tube of pressure-stabilizing 2
Raw stable, pressure stabilization function；So that influent stream tube of pressure-stabilizing 1 and the media flow gone out to flow in the connecting pipeline 3 between tube of pressure-stabilizing 2 keep steady
Pressure, steady flow, the medium that same amount also makes outflow go out to flow in the outflow tube 20 of tube of pressure-stabilizing 2 keep voltage stabilizing, steady flow；Therefore,
The valve 4 for being arranged on influent stream tube of pressure-stabilizing 1 and going out to flow on the connecting pipeline 3 between tube of pressure-stabilizing 2 can fast and accurately carry out flow tune
Section is controlled, and the medium that outflow tube 20 flows out is not fluctuated, flow accurate stable.In rate-of flow 0.3L/H≤Q≤400L/
During H, it can be very good flow and be adjusted, and it is very loud small by pressure medium shadow.
Brief description of the drawings
Fig. 1 is the utility model example structure schematic diagram.
Fig. 2 is another example structure schematic diagram of the utility model.
Embodiment
The utility model includes influent stream tube of pressure-stabilizing 1, goes out to flow tube of pressure-stabilizing 2, is offered on influent stream tube of pressure-stabilizing 1 into flow tube
10, outflow tube 20 is offered on going out to flow tube of pressure-stabilizing 2, in influent stream tube of pressure-stabilizing 1 and is gone out to flow between tube of pressure-stabilizing 2 provided with 3 connecting pipelines
3a, 3b, 3c, 3 connecting pipelines 3a, 3b, 3c respectively on be provided with needle-like valve 4a, 4b, 4c.3 connecting pipelines 3a, 3b, 3c
On needle-like valve 4a, 4b, 4c it is respectively small, in, the needle-like valve of very much not same specification flow.It can be flowed when it is used according to output
The size of amount, selection one or combination unlatching are used, to meet Flow-rate adjustment needs.
Referring to shown in accompanying drawing 1,2 embodiments, influent stream tube of pressure-stabilizing 1 with going out to flow that tube of pressure-stabilizing 2 is side-by-side is mutually permanently connected,
Open up into flow tube 10, opened up going out to flow the upper lateral part of tube of pressure-stabilizing 2 into flow tube 20 in the following side of influent stream tube of pressure-stabilizing 1；
Or opened up on the side end face of cylindrical shape influent stream tube of pressure-stabilizing 1 into flow tube, go out to flow on the side end face of tube of pressure-stabilizing 2 in cylindrical shape
Open up outflow tube；
On going out to flow tube of pressure-stabilizing 2 be provided with pressure gauge 5, to show pressure, it is possible to sight find stream tube of pressure-stabilizing 2 in medium whether
There is pressure oscillation phenomenon.
