Embodiment Construction

[0018] The combined regulating valve for precise flow control proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that the drawings are all in a very simplified form and use imprecise ratios, which are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0019] The core idea of ​​the present invention is that the combined control valve for accurate flow control provided by the present invention can ensure that the pressure (volume) of the gas (liquid) in the container is stable within a certain range or according to a specified rate of change. The opening and closing of each pipeline is controlled by digital signals to realize sudden changes in pipeline flow and achieve the purpose of precise fl...

Abstract

The invention provides a combined regulating valve capable of realizing accurate control on flow. The combined regulating valve comprises a gas inlet pipeline, a gas outlet pipeline and multiple branch pipelines connected between the gas inlet pipeline and the gas outlet pipeline; and each branch pipeline comprises an on / off control valve and a flow control unit. According to the combined regulating valve capable of realizing accurate control on the flow, the condition that the pressure (volume) of the gas (liquid) in a container is stabilized in a certain range or is changed at a certain ratecan be guaranteed through accurate and quick change of the flow of the pipelines. Opening and closing of the pipelines are controlled through digital signals, sudden change of the flow of the pipelines is realized, and the purpose of accurate control on the flow is achieved. The combined regulating valve has the advantages of easiness in control, high precision, short response time and the like.

Description

technical field [0001] The invention relates to the technical field of flow control devices, in particular to a combined regulating valve for realizing accurate flow control. Background technique [0002] The flow controllers in the prior art include pneumatic membrane valves, electric control valves and electric proportional valves, etc., and their input and output are all analog. Coefficient to realize the control of pipeline flow. This method is simple and easy to use, but there is a problem of response delay. The opening of the valve body can only be changed continuously, so the flow control of the pipeline can only be controlled gradually. When the flow of the pipeline is required to change greatly, these All valves require a certain response time, and cannot achieve sudden flow changes in a short period of time. Contents of the invention [0003] The purpose of the present invention is to provide a combined regulating valve for precise flow control, so as to solve ...
