Description

A kind of gas Flowrate Control System
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:
1, structure is simple, easy to operate.
Stablizing 2, by pressure maintaining valve (4) Mass Control flowmeter (6) inlet pressure, pass through the constant of counterbalance valve (8) Mass Control flowmeter (6) outlet pressure simultaneously, thus realize being stablized by the gas flow of mass flowmenter (6), ensure that the accuracy of experimental result.
3, the outlet of counterbalance valve (8) is connected with check valve (9), effectively inhibits system pressure to raise suddenly and the blowback brought, thus ensure that the security of the element before check valve (9).
Accompanying drawing illustrates:
Fig. 1 is a kind of gas Flowrate Control System schematic diagram.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail;
A kind of gas Flowrate Control System as shown in Figure 1, 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), the outlet of intake valve (1) is connected by the entrance of pipeline with filter (2), the outlet of filter (2) is connected by 1 end of pipeline with threeway A (3), 3 ends of 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 pressure maintaining valve (4) is connected by 1 end of pipeline with threeway B (5), 3 ends of 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 mass flowmenter (6) is connected by 1 end of pipeline with threeway C (7), 3 ends of 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 counterbalance valve (8) is connected by the entrance of pipeline with check valve (9), the outlet of check valve (9) is connected with reaction system by pipeline.
During use, open intake valve (1), regulate pressure maintaining valve (4) and counterbalance valve (8) simultaneously, slowly increase the pressure before and after mass flowmenter (6), start to test when the pressure that load cell C (12) records is consistent with the pressure of reaction system.
Here description of the present utility model and application is illustrative; not want by scope restriction of the present utility model in the above-described embodiments; therefore, the utility model is not by the restriction of the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of the utility model protection.
