Conical regulating valve based on combined compensation of external springs, permanent magnets and electromagnets and monitoring method of conical regulating valve

Abstract

The invention discloses a conical regulating valve based on combined compensation of external springs, permanent magnets and electromagnets and a monitoring method of the conical regulating valve. The conical regulating valve mainly comprises a lower connector, a lower air pressure piston, an upper air pressure piston, a lower repulsion permanent magnet, an upper repulsion permanent magnet, a displacement monitoring system, an attraction permanent magnet, an upper spring, a lower spring, a lower repulsion electromagnet, an upper repulsion electromagnet, an outer protection shell, a valve element, a magnetic generation device, a magnetic induction belt and a valve seat. The attraction permanent magnet connected with a balancing weight slides up and down in a sliding way under the action of inertia force, the attraction permanent magnet generates attraction force on the valve element and drives the valve element to move up and down together, and the size of an outlet of a flow channel in the valve seat is changed, so that the rate of the outlet flow of the regulating valve is changed. The force generated by the springs, the electromagnets and the repulsion permanent magnets can control the moving distance of the attraction permanent magnet, so that the moving distance of the valve element is indirectly controlled, and the purpose of accurate control is achieved. The conical regulating valve based on combined compensation of the external springs, the permanent magnets and the electromagnets provided by the invention has the advantages of simple structure, high reliability, low cost, no influence by external atmospheric pressure and the like.

Description

technical field [0001] The invention relates to the technical field of regulating valve devices, in particular to a regulating valve for automatically controlling the flow rate for fluid delivery. [0002] technical background [0003] The regulating valve is also called self-operated balancing valve, flow control valve, flow controller, dynamic balancing valve, and flow balancing valve. Flow, under the action of fluid, the valve can automatically eliminate the flow deviation caused by the remaining pressure head of the pipeline and pressure fluctuations, and keep the set flow unchanged no matter how the system pressure changes. These functions of the valve make the flow adjustment of the pipe network complete at one time. Turn the network adjustment work into a simple flow distribution, and effectively solve the hydraulic imbalance of the pipe network. It is widely used in aerospace, national defense construction, industrial and agricultural production, municipal constructi...

Problems solved by technology

The traditional variable frequency pump can meet the fuel supply of the aircraft under different power, but the electromagnetic interference has a great interference with the electronic equipment, so there is an urgent need for a fully mechanical adaptive pressure regulating valve
