Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

[0019] Such as figure 1 and figure 2 As shown, an intelligent electric valve 1 includes a valve 1, an electric actuator 2 and a positioner 3. The valve 1 is provided with an opening and closing member that can rotate to open or close the valve port, and the electric actuator 2 precisely drives the opening and closing member to rotate. The positioner 3 is installed on the side of the electric actuator 2, and the positioner 3 controls the action of the electric actuator 2.

[0020] Specifically, the locator 3 is provided with a signal acquisition module, a signal conversion module, a data storage module, a display module, and a central control module. The signal acquisition module accurately detects the rotation angle of the opening and closing member and transmits the signal to the data storage module for preservation. The conversion module converts...

Abstract

The invention relates to an intelligent electric valve which comprises a valve body and an electric actuator. The valve body is provided with an opening and closing part capable of being rotated to open or close a valve port. The electric actuator precisely drives the opening and closing part to rotate. The intelligent electric valve further comprises a locating device which is installed on the side of the electric actuator. The locating device is provided with a signal collecting module, a signal converting module, a data storage module, a display module and a central control module. The signal collecting module precisely detects a rotating angle of the opening and closing part and transmits signals to the data storage module to be stored. The signal converting module converts physical signals into electric signals and transmits the electric signals to the display module. The display module displays a position value of the opening and closing part visually. The central control module controls the electric actuator to work to precisely control the rotating angle of the opening and closing part.

Description

technical field [0001] The invention relates to the field of valves, in particular to an intelligent electric valve capable of precisely controlling the opening and closing of the valve. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system. It is a device that makes or stops the medium (liquid, gas, powder) in the piping and equipment and controls its flow. It has the functions of diversion, cut-off , throttling, check, shunt or overflow pressure relief and other functions. Valves are distinguished according to the transmission mode, including manual, electric, hydraulic, pneumatic, electromagnetic, electromagnetic hydraulic, and electrohydraulic. Among them, electric valves are widely used because of their relatively simple structure and low cost. The electric valves usually use the servo motor to directly drive the opening and closing parts to rotate to complete the opening and closing. The openin...
