Programmable control valve

Abstract

The invention belongs to the technical field of valve control, and discloses a programmable control valve. The programmable control valve is flexible in operation, stable, reliable, simple to maintain, good in expansion and low in cost. According to the technical scheme, the programmable control valve comprises a valve body, a power supply input end, a main processing unit, an executing mechanism, an opening degree detection unit, a work state detection unit, a control converting unit and a power supply transformation unit, wherein the valve body is respectively connected with the executing mechanism and the opening degree detection unit, the power supply input end is respectively connected with the executing mechanism, the work state detection unit and the power supply transformation unit, the main processing unit is respectively connected with the opening degree detection unit, the work state detection unit, the control converting unit and the power supply transformation unit, and the executing mechanism is connected with the control converting unit.

Description

technical field [0001] The programmable control valve of the invention belongs to the technical field of valve control. Background technique [0002] At present, the functions of the valves used in fluid or hydraulic control are relatively single, and the valves and their controls that meet the design requirements of conventional or special functions usually require multiple signal devices and another control box to jointly realize, which makes the existing valves and their control systems exist under The above defects: complex functional design, many modules used, many and messy signal and control loop wiring, poor system reliability, large installation space requirements on site, messy layout, high manufacturing cost, difficult maintenance, and cannot be interconnected through the network A series of shortcomings such as realizing autonomous operation or controlled operation of the valve, inflexible modification of the operation mode, etc., generally manifest in that the f...
