Embodiment Construction

[0039] The present invention will be described in detail below with reference to the examples, but the present invention is not limited to these examples.

[0040] An embodiment of the present invention provides a pressure controller, including a control unit 1 and a pressure coarse adjustment unit 2 , a pressure fine adjustment unit 3 and a pressure measurement unit 4 all connected to the control unit 1 .

[0041] The pressure coarse adjustment unit 2 and the pressure fine adjustment unit 3 are arranged in parallel and connected to the gas pipeline. Wherein, the pressure adjustment rate of the coarse pressure adjustment unit 2 is greater than the pressure adjustment rate of the pressure fine adjustment unit 3 .

[0042] In this embodiment, the pressure adjustment rate of the pressure fine adjustment unit 3 is half of the pressure adjustment rate of the pressure coarse adjustment unit 2 . The pressure coarse adjustment unit 2 and the pressure fine adjustment unit 3 are both s...

Abstract

The invention discloses a pressure controller and a control method thereof, belongs to the technical field of pneumatic control, and can effectively shorten the pressure regulation time while ensuring the pressure regulation precision. The pressure controller comprises a control unit, and a pressure coarse adjustment unit, a pressure fine adjustment unit and a pressure measurement unit which are connected with the control unit; the pressure coarse adjustment unit and the pressure fine adjustment unit are arranged in parallel and are connected in a gas pipeline; the pressure measuring unit is arranged at the outlet end of the gas pipeline and is used for measuring the pressure of the outlet end of the gas pipeline in real time; the control unit is used for controlling the pressure coarse adjustment unit and the pressure fine adjustment unit to work at the same time or controlling the pressure fine adjustment unit to work independently according to the difference degree between the outlet end pressure and the target pressure.

Description

technical field [0001] The invention relates to a pressure controller and a control method thereof, belonging to the technical field of pneumatic control. Background technique [0002] A pressure controller is a special instrument for controlling pressure in an industrial process measurement and control system, and is usually called a pressure switch in engineering. It is an electrical switch that uses pressure as a control signal. A pressure controller is an electronic controller that automatically and quickly adjusts the output based on the supply pressure. Due to its high accuracy and control stability, the pressure controller is suitable for use as a pressure reference in production lines and laboratories for automatic testing and / or calibration of various sensors. [0003] When the existing pressure controller works, it is necessary to select a solenoid valve of suitable size according to the target pressure value. If you want to achieve precise pressure control, you...
