Abstract
An electric valve and a thermal management system. The electric valve comprises a pressure sensing unit. The pressure sensing unit is connected to a valve seat, and the pressure sensing unit can sense the pressure characteristics of a working medium in a detection flow channel) and form a piezoelectric signal. An electric control portion comprises an electric control board. The piezoelectric signal forms, by means of a conditioning circuit, an electrical signal corresponding to a pressure. The electrical signal is used as a part for generating a signal for controlling a driving portion.
Claims17
An electric valve, comprising a valve core, a valve seat, an electric control part and a driving part, wherein a first flow passage and a second flow passage are formed in the valve seat, and the electric valve is formed with a valve port, wherein the valve port is located between the first flow passage and the second flow passage, wherein the valve core is capable of moving relative to the valve port and changing the opening degree of the valve port, the electric control part is configured to control the driving part, and the driving part drives the valve core to move, wherein the electric valve further comprises a pressure sensing unit, the pressure sensing unit is connected with the valve seat, and the pressure sensing unit is capable of sensing a pressure characteristic of the working medium in a detection flow passage and form a piezoelectric signal, wherein the electric control part comprises an electric control board, the piezoelectric signal forms an electrical signal corresponding to the pressure characteristic by a conditioning circuit, and the electrical signal is used as a part of a signal for controlling the driving part.
