Technical Field

The invention relates to the technical field of pipeline flow control devices, in particular to a high-pressure filling pipeline flow control device for coal mining.

Background

A Flow control system (Flow control system) is a feedback control system that uses a Flow rate, which is an amount of fluid passing through a pipe per unit time, as a controlled amount, and is an important industrial control system, and is widely used in various industrial sectors, for example, in production processes of chemical industry, petroleum industry, steel industry, coal mine industry, light industry, and the like, and requires control of the Flow rate. The flow control system consists of a flow meter (see a flow sensor) for measuring the controlled flow and converting it into a physical quantity (generally a voltage) which can be directly compared with a given quantity, a regulator and a flow regulating device, wherein when the output of the flow meter deviates from the given quantity, the regulator processes the deviation signal and transmits the deviation signal to the flow regulating device; the flow regulating device adjusts the opening degree of the valve according to the flow rate, so as to change the flow rate in the pipeline to a desired value and keep the flow rate close to the desired value, and the flow regulating device has various forms according to the transmission mode of the fluid.

The flow controller is a linkage device of a perforated plate combination and is a relatively reliable element for solving dynamic hydraulic balance in China at present; it is a dynamic regulating device composed of a flow setting regulating valve, namely a manual adjustable orifice plate (equivalent to a static balance element), two valve clacks, a spring and a diaphragm; the manual adjustable orifice plate is formed by that a user rotates a flow setting adjusting valve by using a special tool according to a circulating flow value of a design load, and the required flow value is adjusted to be aligned with an index value of a flow scale mark; once the flow is set, the value is permanent and is not influenced by the changes of the pressure difference, the load and the like of a heating system, an automatic orifice plate in a self-operated flow control valve automatically adjusts the resistance by taking the pressure difference in the system as power until the residual pressure head in the system is completely eliminated, so that the flow value adjusted by a flow setting adjusting valve is ensured to be constant and permanently kept constant, and the flow adjusting range is limited and sometimes exceeds the control range in the process of controlling the flow of a pipeline, so that the actual flow adjusting and controlling requirement cannot be met under many conditions.
