Electronic controlled throttle valve

Abstract

The invention discloses an electronic controlled throttle valve, and belongs to the technical field of valves. The electronic controlled throttle valve comprises a motor, a valve body and a shell barrel, a transmission rod is arranged between a driving output shaft of the motor and a valve rod of the valve body, a movable transmission torsion structure is arranged at a sectional joint of a transmission shaft, the movable transmission torsion structure divides the transmission shaft into upper and lower parts, a spring which sleeves the transmission shaft and is in a compressed state is furtherarranged on the movable transmission torsion structure, an indicating ring which sleeves the transmission shaft is arranged on the lower part of the spring, the bottom end of the spring abuts againstthe indicating ring and makes the indicating ring press a lower transmission shaft, the top end of the spring abuts against an upper transmission shaft, the two ends of the shell barrel are fixedly connected with the motor and the valve body correspondingly, the transmission rod, the spring and the indicating ring are all located in a barrel cavity of the shell barrel, an indicating window is formed in the shell barrel, and an indicating body penetrating though the indicating window to extending out of the shell barrel is arranged on the indicating ring. The electronic controlled throttle valve has simple structure, convenient and reliable use, high transmission torsion ability, and is suitable for adjusting pipelines with big pressure.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an electronically controlled throttle valve. Background technique [0002] Most of the electronically controlled throttle valves in the prior art are complex in structure and lack the stroke limit function, so they are difficult to be used in pipelines with high pressure such as large hydraulic systems, and cannot meet the needs of current large-scale engineering construction. Contents of the invention [0003] In view of this, the present invention proposes an electronically controlled throttle valve, which has a simple structure and strong torque transmission capability, and is suitable for adjusting high-pressure hydraulic pipelines. [0004] Based on the above-mentioned purpose, the technical scheme provided by the invention is: [0005] An electronically controlled throttle valve, which includes a motor, a valve body and a casing, a drive output shaft of the motor and a va...
