Description
Technical field:
The utility model relates to a kind of fluid delivery system, specifically a kind of gas Flowrate Control System.
Background technology:
Mass flow controller is used for carrying out accurate measurement and control to the mass flow of gas, is widely used in the industries such as petrochemical industry, metallurgy, pharmacy, environment, gas distribution processed.Stable pressure reduction is needed during mass flow controller work, the i.e. pressure of the flow controller entrance pressure height certain value of wanting specific discharge controller to export, and the pressure of the pressure of flow controller entrance and outlet will be stablized, can not fluctuate, such guarantee mass flow controller work normal, flow-control stable.
Summary of the invention:
The purpose of this utility model be to provide a kind of structure simple, be easy to the gas Flowrate Control System that operates, flow-control is stable.
A kind of gas Flowrate Control System described in the utility model, comprise intake valve (1), filter (2), threeway A (3), pressure maintaining valve (4), threeway B (5), mass flowmenter (6), threeway C (7), counterbalance valve (8), check valve (9), load cell A (10), load cell B (11) and load cell C (12), it is characterized in that: the outlet of described intake valve (1) is connected by the entrance of pipeline with filter (2), the outlet of described filter (2) is connected by 1 end of pipeline with threeway A (3), 3 ends of described threeway A (3) are connected with load cell A (10) by pipeline, 2 ends of threeway A (3) are connected by the entrance of pipeline with pressure maintaining valve (4), the outlet of described pressure maintaining valve (4) is connected by 1 end of pipeline with threeway B (5), 3 ends of described threeway B (5) are connected with load cell B (11) by pipeline, 2 ends of threeway B (5) are connected by the entrance of pipeline with mass flowmenter (6), the outlet of described mass flowmenter (6) is connected by 1 end of pipeline with threeway C (7), 3 ends of described threeway C (7) are connected with load cell C (12) by pipeline, 2 ends of threeway C (7) are connected by the entrance of pipeline with counterbalance valve (8), the outlet of described counterbalance valve (8) is connected by the entrance of pipeline with check valve (9), the outlet of described check valve (9) is connected with reaction system by pipeline.
Advantage of the present utility model and good effect:
