Problems solved by technology

[0002] The gas proportional valve includes an electromagnetic drive device, which includes a moving coil assembly and a valve plug. When energized, the moving coil assembly moves axially up and down through magnetic induction, and the moving coil assembly can drive the valve plug to move axially to adjust the gas flowing through the valve port. Due to the uncontrollable vibration of the moving coil assembly in the radial direction during the high-frequency actuation process, it may cause unreliable actuation of the product

Embodiment Construction

[0013] like figure 1 The shown gas proportional valve includes a main valve seat 1, the main valve seat 1 is provided with an inlet 1a and an outlet 1b, the gas flows in from the inlet 1a and flows out from the outlet 1b, the main valve seat 1 can be aluminum alloy die-casting, the main valve seat 1 The electromagnetic drive assembly 2, the servo drive assembly 3 and the electromagnetic drive device 4 are fixedly connected, the inner cavity of the main valve seat 1 is provided with a differential pressure adjusting device 5, and the main valve seat 1 is also provided with a first valve port corresponding to the above valve 11. The second valve port 12, the valve port 13 and the main valve port 14, the gas proportional valve can be used as the main gas safety switch by the electromagnetic drive assembly 2 and the servo drive assembly 3, when one of the two is powered off or two at the same time. When the power is off, the gas flow will be cut off. The electromagnetic drive devi...

Abstract

The gas proportional valve provided by the present invention includes an electromagnetic drive device, and the electromagnetic drive device includes a first reed assembly and a second reed assembly, the first reed assembly includes a first reed, and the first reed includes a first fixing member and a second reed assembly. an elastic part, the second reed assembly includes a second reed, the second reed includes a second fixing part and a second elastic part, and the first elastic part is fixedly connected with the end of the first reel of the reel and the second reed The elastic member is fixedly connected with the end of the second wire frame of the wire frame, and by arranging the first reed assembly and the second reed assembly, the shaking of the moving coil assembly in the radial direction can be reduced, and the operation reliability of the electromagnetic drive device is relatively improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic drive control and gas control, in particular to a gas proportional valve. Background technique [0002] The gas proportional valve includes an electromagnetic drive device, which includes a moving coil assembly and a valve plug. When powered on During the high-frequency operation, the moving coil assembly cannot control its shaking in the radial direction, which may cause unreliable operation of the product. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a gas proportional valve, in which the moving coil assembly can reduce the phenomenon of shaking in the radial direction when it is actuated, and relatively improve the actuation reliability of the gas proportional valve. [0004] The gas proportional valve provided by the present invention includes a main valve seat and an electromagnetic drive device. The main valve seat is provided with a va...
