Electronic control valve assembling method and system

Abstract

The invention discloses an electronic control valve assembling method. An electronic control valve comprises a body, a static iron core, an outer shell assembly, a corrugated pipe and a coil assembly.The assembling method is characterized by comprising the steps that the static iron core is mounted in a stepped hole of the body, so that a first assembly is formed; the outer shell assembly is mounted on the outer side wall of the first assembly, so that a second assembly is formed; the corrugated pipe is mounted on the side, back onto the static iron core, of the body in the second assembly, and the corrugated pipe is positioned and press fitted based on an inner hole and an inner hole plane in the side, facing the body, of the outer shell assembly in the second assembly, so that a third assembly is formed; and the third assembly and the coil assembly are assembled together to obtain the electronic control valve. The corrugated pipe is positioned and press fitted by adopting the outershell assembly inner hole and the inner hole plane, stress directions of a movable iron core during moving are effectively guaranteed to be concentric, and therefore, it is guaranteed that noise of the whole electronic control valve during using is lowered while the frequency per second of the electronic control valve is 400 HZ.

Description

technical field [0001] The present application relates to the technical field of electronics and electronic assembly, and in particular, the present application relates to an electronic control valve assembly method and system. Background technique [0002] The main assembly process in the assembly process of the existing electric control valve is divided into four steps; step 1: assembling the main body and the conduit to form the first assembly, step 2: assembling the first assembly and the outer shell assembly to form the second assembly, Step 3: Assemble the coil assembly with the second component to form the third component. Step 4: Assemble the bellows with the third component. In the process of assembling the bellows and the third component, the coil plane is used to position the bellows on the third component. However, after the electric control valve is assembled, due to the insufficient flatness of the coil plane, the dynamics in the electric control valve There i...

Problems solved by technology

In the process of assembling the bellows and the third component, the coil plane is used to position the bellows on the third component. However, after the assembly of the electric control valve is completed, due to the insufficient flatness of the coil plane There is an eccentric phenomenon of the force on the iron core. During the performance test of the electric control valve, the movable gap between the moving iron core and the magnetic isolation sleeve changes, and the moving iron core is stuck.

And when the vibration frequency of the electric control valve was tested at 400HZ for 1 second, it was found that the vibration of the moving iron core was too large, and the noise of the electric control valve assembly became louder.
