Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a flow amplifying valve which is easy to regulate. Background Art

[0002] The working principle of the flow amplifier valve is to adjust the flow of the fluid by controlling the opening of the valve, and to amplify the small flow into a larger flow. In the automatic control of modern factories, the flow control valve plays a very important role. The production of these factories depends on the correct distribution and control of the flowing medium. These controls, whether it is the exchange of energy, the reduction of pressure or the simple addition of materials to the container, require some final control elements to complete.

[0003] In actual applications, when the existing regulating valve is in the open state, the medium channel is fully open; when the regulating valve is in the closed state, the medium channel is fully closed, so the medium channel has only two states: fully open and closed; the medium flow cannot be adjusted according to actual conditions, so it is not suitable for some occasions where the medium flow requirements are constantly changing.

[0004] To this end, we propose a flow amplification valve that is easy to regulate. Utility Model Content
